INTRODUCTION BACKGROUND In response to the requirements of the Disaster Mitigation Act of 2000 (DMA 2000), Suffolk County (SC), New York has developed this All-Hazard Mitigation Plan (HMP or Plan). DMA 2000 amends the Stafford Act and is designed to improve planning for, response to, and recovery from~ disasters by requiring state and local entities to implement pre-disaster mitigation planning and develop HMPs. The Federal Emergency Management Agency (FEMA) has issued guidelines for HMPs. The New York State Emergency Management Office (NYSEMO) also supports plan development for jurisdictions in New York State. Specifically, DMA 2000 requires that States with support from local governmental agencies develop HMPs to prepare for and reduce the potential impacts of natural hazards. DMA 2000 is intended to facilitate cooperation between state and local authorities, prompting them to work together. This enhanced planning will better enable local and State governments to articulate accurate needs for mitigation, resulting in faster allocation of funding and more effective risk reduction projects. Hazard Mitigation is any sustained action taken to reduce or eliminate the long term risk and effects that can result from specific hazards. FEMA defines a Hazard Mitigation Plan as the documentation of a state or local government evaluation of natural hazards and the strategies to mitigate such hazards. DMA 2000 Origins -The Robert T. Stattbrd Disaster Relief aad Emergency Assistance Act In the early 1990s a new federal policy regarding disasters began to evolve. Rather than simply reacting whenever disasters strike communities, the federal government would encourage communities to first assess their vulnerability to various disasters and then take actions to reduce or eliminate potential risks. The logic is simply that a disaster-resistant community can rebound from a natural disaster with less loss of property or human injury, at much lower cost, and, consequently, more quickly. Moreover, other costs associated with disasters, such as the time lost from productive activity by business and industries, are minimized. DMA 2000 provides an opportunity for States, tribes and local governments to take a new and revitalized approach to mitigation planning. DMA 2000 The Federal Emergency Management Agency (FEMA) estimates that for . every dollar spent on damage prevention (mitigation), twice that amount is saved through avoided post-disaster damage repair. amended the Robert T. Stafford Disaster Relief and Emergency Assistance Act by.repealing the previous mitigation planning provisions (Section 409) and replacing them with a new set of requirements (Section 322). This section sets forth the requirements that communities evaluate natural hazards within their respective jurisdictions and develop an appropriate plan of action to mitigate those hazards, while emphasizing the need for State, tribal and local governments to closely coordinate mitigation planning and implementation efforts. The amended Stafford Act requires that each local jurisdiction identify potential natural hazards to the health, safety and well being of its residents and identify and prioritize actions that can be taken by the community to mitigate those hazards--before disaster strikes. For communities to remain eligible for hazard mitigation assistance from the federal government, they must first prepare a HMP (this plan). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 1-1 DRAFT - September 2007 SECTION 1: INTRODUCTION Responsibility for fulfilling the requirelnents of Section 322 of the Stafford Act and administering the FEMA Hazard Mitigation Program has been delegated to the State of New York. specifically to NYSEMO. FEMA also provides support through guidance, resources, and plan reviews. Copies of the applicable federal and state regulations are found in Appendix A. Organizations Involved in the Mitigation Pla;ming Eflbrt SC intends to implement this plan with the participation of its various departments, organizations and governing body, as well as by coordinating with relevant State, and federal entities. Coordination helps to ensure that stakeholders have established connnunication channels and relationships necessary to support mitigation planning and mitigation actions included in Section 6. In addition to SC, the following jurisdictions have participated in the planning process: Town of Babylon Village of Amityville Town of Huntington Village of Asharoken Town of Riverhead Village of Babylon Town of Shelter Island Village of Bellport Town of Smithtown Village of Head of Harbor Town of Southold Village of Huntington Bay Village of Nissequoque Village of Nodhport Village of The Branch Multiple Ageacy Support for Hazard Mitigation Primary responsibility for the development and implementation of mitigation strategies and policies lies with local governments. However, local governments are not alone; various parmers and resources at the regional, state and federal levels are available to assist communities in the development and implementation of mitigation strategies. Within New York State (NYS), NYSEMO is the lead agency providing hazard mitigation planning assistance to local jurisdictions. NYSEMO provides guidance to support mitigation planning. In addition, FEMA provides grants, tools, and training to support mitigation planning. Additional input and support for this planning effort was obtained from a range of agencies and through public involvement (as discussed in Section 3). Oversight for the preparation of this plan was provided by the SC Hazard Mitigation Planning Committee (Planning Committee), which includes representatives fl'oml · SC Fire Rescue and Emergency Services · SC Planning Department · Town of Babylon Fire Marshall's Office and Department of Planning and Development · Town of Huntington Supervisor's Office · Town of Riverhead Police · Town of Shelter Island Police · Town of Smithtown Public Safety, Fire Marshall and Engineer's Office · Town of Southold Code Enforcement DM~ 20~0 R~ Miiigatin~ Piah, ~Uff~l~ ~e~ni~i I%~ 90rk i-2 DRAFT - September 2007 SECTION t: INTRODUCTION · Village of Ashroken Mayor's Office · Village of Bellport Code Enforcement · Village of Huntington Bay Police · Village of Northport Police This HMP was prepared in accordance with the following regulations and guidance: · DMA 2000 (Public Law 106-390, October 30. 2000). · 44 Code of Federal Regulations (CFR) Parts 201 and 206 (including: Feb. 26, 2002, Oct. 1, 2002, Oct. 28, 2003, and Sept. 13, 2004 Interim Final Rules). · FEMA. 2004.

To support the planning process to develop this HMP, SC and the participating jurisdictions have accomplished the following: · Developed a MPC · Identified hazards of concern and hazards of interest · Profiled these hazards · Estimated the inventory at risk and potential losses associated with these hazards · Developed mitigation actions and goals that address the various hazards that impact the area · Developed mitigation plan maintenance procedures to be executed after obtaining approval of the plan from NYSEMO and FEMA To address the requirements of DMA 2000 and better understand their potential vulnerability to and losses associated with hazards of concern, SC used the Hazards U.S. - Multi-Hazard (HAZUS-MH) soft:ware package (discussed in greater detail later in this Plan) supplemented by local data, as feasible, to support the risk assessment and vulnerability evaluation. HAZUS-~MH assesses risk and estimates potential losses for natural hazards. It produces outputs that will assist state and local governments, communities, and the private sector in implementing emergency response, recovery, and mitigation programs, including the development of HMPs. As required by DMA 2000, the planning process has informed the public and provided opportunities for public comment and input. In addition, numerous agencies and stakeholders have participated as core 9r s6pport members, providing input and expertise throughout the planning process. This Multi-Jurisdictional Hazard Mitigation Plan documents the process and outcomes of the County and jurisdictions' efforts. Additional information on the planning process is included in Section 3, Planning Process. Documentation that the prerequisites for plan approval have been met is included in Section 2, Plan Adoption. Benefits of Mitigation Planning The planning process will help prepare citizens and government agencies to better respond when disasters occur. Also, mitigation planning allows SC and participating jurisdictions to remain eligible for mitigation grant funding for mitigation projects that will reduce the impact of future disaster events. The long-term benefits of mitigation planning include: · An increased understanding of hazards faced by SC · A more sustainable and disaster-resistant community · Financial savings through partnerships that support planning and mitigation efforts · Focused use of limited resources on hazards that have the biggest impact on the community · Reduced long-term impacts and damages to human health and structm'es and reduced repair costs Organization of this Mitigation Plan This Plan was organized in accordance with FEMA and NYSEMO guidance, and its structure follows the four-phase planning process recommended by FEMA and summarized in Figure 1-2. The Plan is DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 1-4 DRAFT- September 2007 SECTION 1: INTRODUCTION organized into two volumes: Volume I includes all information that applies to the entire planning area (SC); and Volume 2 includes participating jurisdiction-specific information.

DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 1-5 DRAFT - September 2007 SECTION 1: INTRODUCTION Figure 1-1. SC Multi-Jurisdictional Hazard Mitigation Plmmiug Process Phase 1: Orqanize Resources The Planning Committee is developed; resources are identified and obtained; public involvement is initiated. Technical, regulatory, and planning experts are identified to support the planning process. Phase 2: Assess Risks The Planning Committee, with appropriate input, identifies potential hazards, collects data, and evaluates the characteristics and potential consequences of natural hazards on the community. Phase 3: Develop a Mitiqation Plan The Planning Committee uses the risk assessment process and stakeholder input to understand the risks posed by natural hazards, determine what its mitigation priorities should be, and identify options to avoid or minimize undesired effects. The results are a hazard mitigation plan, including mitigation strategies and a plan for implementation. HAZUS-MH was applied to assist SC: · Identify Hazards (Phase 2) · Profile Hazards (Phase 2) · Perform a Vulnerability Assessment (Phase 2) including: - Inventory Assets - Estimate Losses - Evaluate Development Trends - Present Results of Risk Assessment These results provide an input to Phase 3. Phase 4: Implement the Plan and Monitor ProRress The Planning committee brings the plan to life in a variety of ways including: implementing specific mitigation projects; changing the day-to-day operation of SC and participating jurisdictions, as necessary, to support mitigation goals; and monitoring progress and updating the plan over time.

DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 1-7 DRAFT - September 2007 SECTION 2: PLAN ADOPTION SECTION 2: PLAN ADOPTION OVERVIEW This section contains information regarding adoption of the Plan by SC and each pmticipating jurisdiction. Plan Adoption by Local Governing Bodies Adoption by the local governing bodies demonstrates the commitment of SC and each participating jurisdiction to fulfill the mitigation goals and objectives outlined in the Plan. Adoption legitimizes the Plan and authorizes responsible agencies to exectite their responsibilities. In order for the multi-jurisdictional plan to be approved, each jurisdiction included in the Plan must have its governing body adopt the Plan before its submission to NYSEMO and FEMA, even when a cross- jurisdiction agency has the authority to prepare such plans in the name of the respective jurisdictions. Each participating jurisdiction will proceed with formal adoption proceedings when FEMA provides conditional approval of this Plan. Each participating jurisdiction understands that a conditional approval of the Plan will be provided for those municipalities that meet the planning requirements with the exception of the adoption requirement . as stated above. Following adoption or formal action on the Plan, each participating jurisdiction must submit a copy of the resolution or other legal instrument showing formal adoption (acceptance) of the Plan to NYSEMO. These will then be submitted to FEMA with the resolution in Appendix B of this Plan. Each participating jurisdiction understands that FEMA will transmit acknowledgement of verification of formal plan adoption and the official approval of the plan to the mitigation plan coordinator. In addition to being required by DMA 2000, adoption of the plan is necessary because: It lends authority to the plan to serve as a guiding document for all local and state government officials; It gives legal status to the plan in the event it is challenged in court; It certifies the program and grant administrators that the plan's recommendations have been properly considered and approved by the governing authority and jurisdictions' citizens; and It helps to ensure the continuity of mitigation programs ~nd policies over time because elected officials, staff, and other community decision- makers can refer to the official document when making decisions about the community's futura.

The resolutions issued to support adoption of the plan by each jurisdiction are included as Appendix B, Resolutions of Plan Adoption. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 2-1 DRAFT- September 2007 SECTION 3: PLANNING PROCESS SECTION 3: PLANNING PROCESS INTRODUCTION This section includes a description of the planning process used to develop the Plan, including how it was prepared, who was involved in the process, and how the public was involved. To ensure that the Plan met the requirements of the DMA 2000, an approach to the planning process and plan documentation was developed to achieve the following goals: The plan will be multi-jurisdictional and consider all natural hazards facing the area, thereby satisfying the natural hazards mitigation planning requirements specified in DMA 2000. In addition to SC, the following jurisdictions have participated in the planning process. Please note, on February 2, 2007 the Village of Lake Grove decided not to participate further in the planning process. Town cf Babylon Village cf Amityville Town cf Huntington Village cf Asharoken Town of Riverhead Village of Baby~on Town of Shelter Island Village of Bellport Town cf Smithtown- Village cf Head of Harbor Town of Southold Village of Huntington Bay Village cf Nissequoque Village cf Northport Viltage of The Branch The Plan will be developed following the process outlined by DMA 2000, FEMA regulations, and FEMA and NYSEMO guidance. Following this process will ensure all the requirements are met and support Plan review. In addition, this Plan will meet criteria for CRS and the Flood Mitiation Assistance (FMA) programs. Thc SC Multi-Jurisdictional HMP was written using the best available information obtained from a wide variety of sources. Throughout plan development, a concerted effort was made to gather information from participating municipal and county agencies and staff as well as stakeholders, federal and state agencies, and the residents of the County. The Planning Committee solicited information from local agencies and individuals with specific knowledge of certain natural hazards and past historical events, as x~cll as considering planning and zoning codes, ordinances, and other recent planning decisions. The natural hazard mitigation strategies identified in this plan have been developed through an extensive planning process involving county and local agencies, municipal officials and staff, and SC residents. This section of the Plan describes the mitigation planning process, including (1) Planning Committee inxolx ement and efforts; (2) County and local involvement; (3) stakeholder and public involvemept; and 14} integration of existing data, plans, and information. PLANNING COMMITTEE AND OTHER STAKEHOLDER SUPPORT Many parties supported preparation of this plan; the Planning Committee and other stakeholders involved m the process are presented below. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 3-1 DRAFT- September 2007 SECTION 3: PLANNING PROCESS Plamling Committee h~volve[nent and Eltbrts On February 15 2005, SC applied for funding under the Pre-Disaster Mitigation Competitive FY05 Grafit Program to aid in the development of an HMP. FEMA awarded SC a Pre-Disaster Mitigation Grant on October 3, 2005. A Planning Committee was assembled to oversee the development of the Plan, consisting of representatives from SC FRES, SC Planning Department and the six {6) participating towns and nine (9) participating villages. As stated earlier, in February 2007 the Village of Lake Grove decided not to participate further in the planning process. Therefore, the Planning Committee presented in this section represents the current participating jurisdictions and members at the time of publication of the draft Plan (i.e., six participating towns and eight participating villages). The Planning Committee was charged with the following: · Establish Plan development goals; · Establish a timeline for completion of the Plan; · Ensure that the Plan meets the requirements of DMA 2000 and FEMA and NYSEMO guidance; · Solicit and encourage the participation of regional agencies, a range of stakeholders, and citizens in the Plan development process; · Assist in gathering information for inclusion in the Plan, including the use of previously developed reports and data; · Organize and oversee the public involvement process; · Develop, revise, adopt, and maintain the Plan. In addition to a Planning Committee, a GIS sub-committee was formed consisting of technical respresentatives to discuss the gathering and sharing of available spaital data througout the planning process. On October 27, 2005, the SC Planning Connnittee met for the first time and continued to meet regularly throughout the year. Table 3-1 shows the current members of the Planning Committee, at the time of this draft Plan's publication. On September 14, 2006, a kick-off meeting was held with the consultant to begin Plan development. Thereafter, members of the Planning Committee, as well as key stakeholders, convened monthly to share information and participate in workshops to identify hazards; assess risks; identify critical facilities; assist in developing mitigation goals, objectives and actions; and provide continuity through the plan development process to ensure that natural hazards vulnerability information and mitigation strategies were also incorporated into the Plan. In addition, County-wide training on the use of HAZUS-MH for risk assessment was run parallel to one of the regular committee meetings (see Table 3-2). Each member of the Planning Committee reviewed the Plan and supported interaction with other stakeholders and assisted with public involvement efforts. Table 3-1.

Representatives of SC, Planning Committee members and the consultant supported local g6vemment meetings in each of the six participating towns during the data collection phase of the project. These meetings allowed an opportunity to explain the requirements for and benefits of DMA 2000 planning, detailed the planning process and need for local input, and helped to identify specific needs, concerns and issues in each jurisdiction. Further, these meetings provided an opportunity to make local government . officials aware of the project and the need for them to eventually adopt the Plan by resolution (see Table 3-2). Representatives of SC and/or their consultant facilitated or attended meetings with stakeholders, including local governments within SC. The Towns of Islip, Southampton and East Hampton are engaging in DMA 2000 planning programs, and SC actively supports these efforts throughout their planning process. In addition to the exchange of information and data, SC FRES serves as a Planning Committee member for the Town of lslip's Plan, attends meetings in both the Towns of East Hampton and Islip regarding the development of their Plans, and the Town of Southampton has attended SC Planning Committee meetings (see Table 3-2). Additionally, the Supervisors of Brookhaven, and lslip have also been regularly informed of the SC Plan's planning efforts. NYS Senator John J. Flanagan and SC Legislature John Kennedy have also been regularly updated on the planning progress. SC FRES has communicated with Nassau County's Office of Emergency Management on numerous occasions regarding the preparation of both Counties' HMPs. Additionally, SC has been monitoring the preparation of Nassau's Plan via their public website (http://www.nassaucountynv.eov/agencies/OEM/hazmit/hazmitDP.html). SC and Nassau County OEM also attended a meeting at LIPA/Keyspan regarding priority critical facilities that need power returned after a natural hazard event. In addition to monthly Planning Committee meetings, there was a great deal of communication between Planning Committee members through electronic mail (email), by phone, and via a secure collaborative web site. The consultant established the.secure, collaborative website for the sharing of information and data amongst the Planning Committee. The County and local planning participants, NYSEMO, and stakeholders have been provided with access. This site was designed to facilitate the sharing of data and information, post notices, and helped maintain communication between meetings. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 3-3 DRAFT- September 2007 SECTION 3: PLANNING PROCESS Stakeholders, non-participating Towns and members of local government were invited to pertinent Planning Committee meetings. Attendees included the Long Island Chapter of The Nature Conservancy, NYS Department of Transportation (Long Island Region), representatives from Legislature Kennedy's office, and representative from the non-participating Town of Southampton. In addition, the local electric and gas utilities, LIPA and Keyspan, have been invited to actively participate in the Planning Coimnittee meetings. Individual meetings with certain key stakeholders were conducted, including the Long Island Chapter of The Nature Conservancy, NYS Department of Transportation (Long Island Region), and U.S. Geologic Survey. Other stakeholders and SC Departments that have been contacted and information requested from include: SC Health Department; SC Water Authority; SC Real Property; SC Treasurer's Office; New York Sea Grant (SUNY Stonybrook); USACE (NY Division); NYS DEC; NYS DOS; SEMO; and FEMA Region 2. After completion of the Plan, implementation and ongoing maintenance will become a function of the Planning Committee. The Planning Committee will review the Plan and accept public comment as part of an annual review and as part of 5 year mitigation plan updates.

Stakeholders Involved iu Mitigation Planniug This section presents ( 1 ) County and participating jurisdiction involvement, (2) State and regional agency involvement, and (3) public participation - citizen involvement. Municipal and Local Involvement The Planning Conunittee and/or its members met and connnunicated with NYSEMO and other SC departments regularly to obtain mitigation planning information and general guidance on HMP preparation. The SC Departments that the Planning Committee met and/or communicated with include: · Suffolk County Department of Health Services · Suffolk County Department of Parks · Suffolk County Department of Public Works · Suffolk County Fire Rescue and Emergency Services · Suffolk County GIS Department · Suffolk County Office of Emergency Preparedness · Suffolk County Office of Real Property Services · Suffolk County Planning Department · Suffolk County Legistature John Kennedy's Office · Suffolk County Treasurer's Office · Suffolk County IT Department SC FRES has also communicated with Nassau County's Office of Emergency Management regarding the progress and status of SC's Plan and Nassau County's progress on their hazard mitigation plan. Addilionally, SC FRES and Nassau OEM .have attended meetings with mutual stakeholders ILI PA:Keyspan) to discuss critical facilities. Thc Towns of Brookhaven, East Hampton, Islip and Southampton are not participating in the SC Plan. ttowexer, SC FRES has kept these towns apprised of SC's planning efforts, met with each town indix idually to discuss Plan progress and distribute materials for their review and comment, and invited all non-participating towns to pertinent MPC meetings. Additionally, the Town of lslip is preparing a separate single-jurisdiction plan. SC FRES serves as a member on their Plan's committee and regularly atlcnds their scheduled planning meetings. State and Regional Agency Involvement hdbrmation regarding hazard identification, risk assessment, and mitigation strategies for this Plan was also requested and received from the following agencies and organizations: · American Red Cross (ARC) ~ ~ DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 3-11 [ '1~:;I DRAFT- September 2007 SECTION 3: PLANNING PROCESS · FEMA · Long Island Power Authority (LIPA)/Keyspan · National Weather Service(NWS) · National Oceanic and Atmospheric Agency (NOAA) · New York State Department of Environmental Conservation (NYSDEC) · NYSEMO · New York State Department of State · New York State Department of Transportation · New York Sea Grant (SUNY Stonybrook) · Suffolk County Water Authority · The Nature Conservancy - Long Island Chapter · U.S. Army Corp of Engineers (NY Division) · U.S. Geological Survey (USGS) Public Participation - Citizen Involvement In order to facilitate coordination and communication between the Planning Committee and citizens, numerous methods of public outreach were conducted to inform the public of the Plan and encourage participation in the planning process. The Planning Committee has made the following efforts toward public participation in the development and review of the Plan: A public website (x~ x~ w.su ffulkcountvn¥.gox.:RESPOND) was launched to inform SC residents of the project. The website contains information on the project, members of the Planning Committee, methods the public can participate in the planning process, and links to SC resources regarding natural hazard preparedness and mitigation. Public notices and advertisements were posted to invite residents to public of meetings held in each of the six participating Town during May and June 2006 (see Table 2-2 for meeting dates). The public meeting dates and agendas were also made available on the public website. These meetings provided the County and Towns an opportunity to present the planning project, present and discuss the hazards of concern and related hazard profiles and vulnerability assessments, and elicit public input to the planning process. A second round of public meetings is scheduled to take place during the Fall 2007. The purpose of these meetings is to update the public on the status of the plan, and continue to elicit their input. A natural hazards preparedness questionnaire was developed and distributed at each of the public meetings to gauge household preparedness for hazards that may impact the County and to assess the level of knowledge of tools and techniques to assist in reducing risk and loss from those hazards. The questionnaire was also available on the public website for residents to complete in electronic format. Additionally, each of the participating towns mailed the questionnaires to households within their jurisdiction. The questionnaire asked 24 quantifiable questions about citizen perception of risk, knowledge of mitigation, and support of community programs. The questionnaire also asked several demographic questions to help analyze trends. The survey was completed online and/or returned to the municipalities, and all results were compiled. The Planning Committee used the survey results as a DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 3-12 DRAFT - September 2007 SECTION 3: PLANNING PROCESS guide when establishing goals, objectives and ~nitigation strategies for the Plan. Appendix C provides a summary of the survey and survey findings. The Draft Plan will be posted to the public website. Availablility of the Draft Plan at additional venues will be discussed at the next MPC meeting on September 27, 2007. A second opportunity for public cotmnent will be provided for the Final Plan that will be submitted to NYSEMO/FEMA. At that time, the Plan will be provided for public comment in the same manner and format as the Draft Plan. · Several articles have also been published in local newspaper (i.e., Newsday and The Long Islander), describing the Plan and discussihg the na .rural hazards Long Island faces. COORDINATION WITH EXISTING PLANNING EFFORTS AND PROGRAMS Local municipalities are charged with the development of local HMPs required under Section 322 of the Stafford Act by New York. Therefore, the Planning Committee coordinated the development of this HMP. In New York, Article 2B Section 23 of State Executive Law authorizes-local communities to prepare local disaster plans based on the contention that local municipalities are best equipped ~ro assess their strengths and weaknesses, opportunities, and constraints. Local governments have intimate knowledge of the local geography, and in a disaster, local government personnel are on the front lines providing personnel and equipment to support the community. Examples of other hazard mitigation programs in which SC is involved with are the National Flood ' Insurance Program (NFIP) and the Hazard Mitigation Grant Program (HMGP). These programs assist the County in receiving funding for flood mitigation projects and flood insurance (this Plan can also provide funds to mitigate other natural hazards). Data from the County, based on participation in these programs, was incorporated in the risk assessment in Section 5 and used to identify mitigation options in Section Continued involvement in these flood-related programs will help to administer funds and resources to support this HMP. Hazard Mitigation Grant Program Participation in FEMA 404 HMGP may cover mitigation activities including raising, removing, relocating or replacing structures within flood hazard areas. SC has applied for assistance through FEMA 404 HMGP for several projects in the past. INSERT PROJECTS HERE National Fhlod Insurance Prograln Established in 1968, the NFIP provides federally-backed flood insurance to residents of communities that enact and enforce regulations that more carefully regulate development within floodplain areas. For individual property owners to be eligible to buy the federally-backed flood insurance, their property must be located within a community that participates in NFIP. For a community to be eligible in NFIP, it must adopt and enforce a floodplain management ordinance to regulate proposed development in floodplains and officially designate a local floodplain coordinator/administrator. The intent of the program is to ensure that new construction does not exacerbate existing flood hazards and is designed to better withstand flooding. SC has enacted and enforced floodplain management ordinances as required. The community also has Flood Insurance Rate Maps (FIRM) that at a minimum show floodways, 100-year flood zones, and 500-year flood zones. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 3-13 DRAFT- September 2007 SECTION 3: PLANNING PROCESS Mitigation activities related to this program are included in Section 6 and data from FEMA Region II regarding NFIP Insurance Reports was used in the risk assessment for the flood hazard included in Section 5. All participating Towns and Villages of this Plan participate in NFIP. Table 3-3 summarizes the local floodplain managers in SC and participating Towns and Villages. Table 3-3.

All other participating Villages indicated they do not have a floodplain manager. Comnmnity Rating System (CRS) The NFIP has been successful in protecting property owners who acquire flood insurance through the. program from catastrophic financial losses due to flooding, and in requiring that new buildings constructed within 100-year flood plains are better protected from flood damage. In thc 1990s, the Flood Insurance Administration (FIA) established the CRS to encourage local governments to increase their standards for floodplain development. The goal of this program is to encourage communities, through flood insurance rate adjustments, to implement standards above and beyond the minimum required in order to: · Reduce losses from floods · Facilitate accurate insurance ratings · Promote public awareness of the availability of Bood insurance CRS is a xrotuntary program designed to reward participating jurisdictions for their efforts to create more disaster-resistant communities using the principles of sustainable development and management. The Town of Babylon and the Village of Northport in the Town of Huntington already participate in CRS (date classified October 1, 1993). This Plan will also meet CRS criteria. Active involvement in this program is included as a mitigation activity in Section 6. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 3-14 DRAFT - September 2007 SECTION 3: PLANNING PROCESS Integration of Existing Data and Plans into Mitigation Plan The mitigation plan integrates local and federal data as discussed below. i,ocal Data The Planning Committee reviewed and incorporated existing data and plans to support the mitigation plan. A number of electronic and hard copy documents were made available to support the planning process. These documents are too numerous to list below; therefore, a summary is provided. A complete listing is included in the references section of this document. · SC and Town Geographic Information System (GIS) data · Documentation of past mitigation actions and grant applications · Historic maps · County and Town Comprehensive and Emergency Plans · Natural Hazard Emergency Response Plans · Published documents provided SC Department of Planning, USACE, NYS Governor's Coastal Erosion Task Force, LIPA Cross-referencing this Plan with docmnents like those above are updated will need to occur and has been included in Section 6 as mitigation activities. Federal and State Data Federal and State data was collected and used throughout the mitigation process including: · US Census data · HAZUS-MH provided data · FEMA"How To" Series (386-1 to 386-4, and 386-7) · Data from the National Oceanic and Atmospheric Administration (NOAA) · NYS DEC Coastal Erosion Hazard Area (CEHA) data · Public laws and other programs such as the NF1P were examined to complete this Plan. A complete list of the existing data and plans used to support this HMP is included in the references section of this document. By incorporating data from existing programs into this mitigation plan, the County also was able to identify the relevance of mitigation planning to these existing programs. Implementation of this Plan through these existing plans is identified as a specific mitigation action in several areas in Section 6 of this Plan. CONTINUED PUBLIC INVOLVEMENT - WE NEED TO DISCUSS WITH MPC SC is committed to the continued involvement of the public. Therefore, copies of the Plan will be made available for review on their public website. A notice regarding annual updates of the Plan and the location of Plan copies will be publicized annually after the Planning Committee's annual evaluation and posted on the public web site. Additionally, updates will be provided at XXXXXX meetings, as appropriate. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 3-15 DRAFT - September 2007 SECTION 3: PLANNING PROCESS INSERT NAME AND TITLE is responsible for receiving, tracking, and filing public comlnents regarding this Plan. Contact information is: XXXXX, XXXX, NY XXXX; Phone: XXX-XXX-XXXX. The public will have an opportunity to comment on the Plan as a part of the annual mitigation planning evaluation process and the 5-year mitigation plan update. The INSERT TITLE is responsible for coordinating the plan evaluation portion of the meeting, soliciting feedback, collecting and reviewing the comments, and ensuring their incorporation in the 5-year plan update as appropriate; however, members of the Planning Committee will assist the INSERT TITLE. Additional meetings may also be held as deemed necessary by the Planning Committee. The purpose of these meetings would be to provide the public an opportunity to express concerns, opinions, and ideas about the Plan. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 3-16 DRAFT - September 2007 SECTION 4: COUNTY PROFILE SECTION 4: COUNTY PROFILE Profile information is presented and analyzed to develop an understanding of a study area, including the economic, structural, and population assets at risk and the particular concerns that may be present related to hazards to be analyzed later in this plan (for example, significant coastal areas or low lying areas prone to flooding or a high percentage of elderly, vulnerable persons in an area). This section provides a profile of Suffolk County (SC), including: ( 1 ) general information (physical setting, location, topography, hydrography ad hydrology, geology, climate, land use and cover, and land use trends, agricultural land use trends), (2) population and demographics (year-round population and seasonal population, and year round and seasonal population trends), (3) general building stock, (4) critical facilities (essential, emergency, hospital and medical, and shelters), (5) transportation systems (including highways and highway bridges, railroads, airports, lifeline utility systems (potable water supply, wastewater, utilities), (6) high potential loss facilities (dams, military, and hazardous material, and communications, and user-defined facilities). GENERAL INFORMATION SC was established on November 1, 1683, as one of the ten original counties in NYS. SC was named after the county of Suffolk in England, from where many of its earliest settlers originated (SC Planning Department, 2005). SC's western border is approximately 15 miles from the eastern border of New York City. According to the 2006 U.S. Census data, the SC estimated population is 1,469,715. The population of SC is larger than twelve states and ranks as the 21st most populated county in the country (U.S. Census, 2006). SC is bordered by Nassau County to the west and major water bodies to the north, south, and east. SC includes rural landscape, residential areas, business districts, commercial/industrial areas, various transportation systems (local and state roadways, railway, airport, etc.), various terrains and natural features, approximately 1,000 miles of shoreline, 70,000 acres of parkland, and educational facilities. In 2002, SC had 34,127 acres of farmland and was the leading county in NYS in the production of many crops. SC continues to experience labor force growth and the number of available jobs has increased within the County since 2005 (SC Planning Department, 2005). This combination of natural and developed features lays the foundation for SC's vulnerability to natural hazards, both in terms of exposure to hazard events and the potential impact of hazard events. SC leads all other NYS counties in the market value of agricultural products sold. In 2002, SC had 34,127 acres of farmland and was the leading county in NYS in the production of many crops. The North Shore Health System is the largest employer in both Suffolk and Nassau Counties. Fifteen colleges and universities are located throughout SC. SC is home to 84 golf courses, including Shinnecock Country Club in Southampton, where the 2004 U.S. Open was held. Tourism is an important part of SC's economy, especially in the eastern portion of the County (SC Department of Planning, 2005). With miles of shoreline, acres of parkland, and many seasonal homes, SC is found by many to be an attractive place to live or visit. Ph3 sical Setting This section presents location, topography, hydrology and hydrography, geology, climate, land use and land cover, land use trends, and agricultural trends. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-1 DRAFT- September 2007 SECTION 4: COUNTY PROFILE Location SC is part of the Long Island Region. located at the southern tip of NYS and east of New York City. SC's land area is approximately 911 square miles. The County is 86 miles long and approximately 15 miles wide. The County is bordered by Nassau County to the west, by the Long Island Sound to the north, the south shore bays and the Atlantic Ocean to the south, and the Peconic Bay System and Gardiner's Bay to the east. The eastern end of SC is divided into two peninsulas, the North Fork and the South Fork, and contains large bays. The County itself is divided into ten towns, which contain many villages and hamlets (Figure 4-1). Figure 4-1. SC, New York SUFFOLK COUNTY~ NEW YORK Source: SC P arming Department Topography The topography of SC and Long Island is relatively flat. Elevations in SC range from 0 feet above sea level along the south shore coast of the Atlantic Ocean to 200 feet above sea level in the central and northern parts of SC. The coast provides approximately 1,000 miles of shoreline. The north shore is characterized by headlands that have been steeply eroded into nearly vertical bluffs that reach almost 100 feet high in certain locations. Along the south shore, waves and ocean currents reworked the deposits to form barrier beaches (Bennington, 2005). Hydrography and Hydrology Numerous ponds, lakes, creeks, extensive bays, and frontages on the Long Island Soulad and Atlantic Ocean make up the waterscape of SC. The major waterways within SC include: the Peconic River, Nissequogue River, Carlls River, Patchogue River, Swan River, Wading River, Carmans River, Great Peconic Bay, Little Peconic Bay, Napeague Bay, Gardiners Bay, Shinnecock Bay, Narrow Bay, Great South Bay, Smithtown Bay, Shelter Island Sound, Long Island Sound, Block Island Sound, and the Atlantic Ocean. All of these water bodies are a part of the Long Island Watershed, which SC is a part of. The Long island Watershed covers more than 16,000 square miles in six different states and a small portion of Quebec, Canada. An estimated 8 million people live within this watershed (Green-CT, 2002). In SC, the Long Island Sound Watershed is broken into the North and South. The South Long Island Watershed consists of 625 miles of streams and has a drainage area of 1,961 square miles. Eighteen major water bodies comprise this watershed in both Nassau and Suffolk Counties. The North Long Island Watershed consists of 52 miles of streams and has a drainage area of 912 square miles (NYS-DEC, 1998). DMA 2000 HaZard Mitigation Plan L Suffolk county, New ~0rk 4-2 DRAFT - September 2007 SECTION 4: COUNTY PROFILE Precipitation is the source of all naturally occurring fresh groundwater and surface water in SC. All drinking water on Long Island comes from underground sources. The groundwater reservoir of SC is made up of aquifers and there are three major aquifers found beneath SC. The three main water-bearing units on Long Island, New York the upper glacial aquifer (water table) and the underlying Magothy and Lloyd aquifers--are the sole source of water supply for more than 3 million people. The deepest aquifer is the Lloyd Aquifer, and it contains water that is up to several thousand years old. The middle aquifer is called the Magothy Aquifer, and it contains water that is up to 1,000 years old in its deepest layers underlying the south shore. This is the largest aquifer and the primary source of public water supply for SC. The shallowest aquifer is called the Upper Glacial Aquifer (SCWA, 2002). The relative abundance of fresh ground water on Long Island has allowed extensive growth and development. About 3.1 million people on Long island rely on water pumped from about 1,000 public supply wells that withdraw about 400 million gallons per day (Mgal/d) from the ground-water reservoir (Nemickas and others, 1989). Geology Long Island is located within the Atlantic Coastal Plain, one of the eight major physiographic regions of NYS. The region is underlain by poorly consolidated sedimentary formations of Cretaceous, Tertiary, and Quaternary age formations that gently dip seaward. SC is underlain by predominantly by Quaternary age sedimentary rocks. Wisconsin Glacial Till is apparent everywhere on Long Island. This type of glacial till consists of an unstratified mix of clay, silt, and sand within a mix of rock material ranging from pebbles to giant boulders (USGS, 2003). The present landscape of SC was formed relatively recently, beginning approximately 11,000 years ago. As the glaciers receded, deposits of moraine were left behind on the island. The terminal moraine is represented by two ridges that extend the length of Long Island. The southern portion of Long Island consists of an older moraine, the Ronkonkoma moraine. The northern portion of Long Island consists of a younger moraine, Harbor Hill moraine, found along Long Island Sound. Outwash sand and gravel deposits cover much of southern Long lsland. Varved lake clays and swamp peat cover areas flooded by lakes that formed in lowland regions shortly after the glaciers receded (Newsday.com, Date Unknown). Climate The climate of NYS is very similar to most of the Northeast United States and is classified as Humid Continental. Long Island's climate is similar to other coastal areas of the Northeast. Summers are typically warm, with an occasional thunderstorm. Sea breezes off the Atlantic Ocean temper the heat and limit the frequency and severity of thunderstorms. During the winter, temperatures are usually warmer than inland areas, sometimes bringing rain instead of snow. Measurable snow falls every winter, including Nor'easters which produce blizzard conditions. These Nor'easters can bring one to two feet of snow with near-hurricane force winds (Longlsland. com, Date Unknown). Mean annual precipitation ranges from 41 to 45 inches in western parts of Long Island, from 42 to 50 inches in the central part, and from 42 to 46 inches in the eastern part (Miller and Frederick, 1969). The winter average temperature in SC is 32.4 degrees Fahrenheit with a summer average of 71.9 degrees Fahrenheit (Longlsland. com, Date Unknown). Differences in latitude, character of topography, and proximity to large bodies of water all have an effect on the climate across NYS. Precipitation during the warm, growing season (April through September) is characterized by convective storms that generally form in advance of an eastward moving cold fronts or during periods of local atmospheric instability. Occasionally, tropical cyclones will move up from DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-3 DRAFT- September 2007 SECTION 4: COUNTY PROFILE southern coastal areas and produce large quantities of rain. Both types of storms typically are characterized by relatively short periods of intense precipitation that produce large amounts of surface runoff and little recharge (Cornell, Date Unknown). The cool season (October through March) is characterized by large, low-pressure systems that move northeastward along the Atlantic coast or the western side of ]the Appalachian Mountains. Storms that form in these systems are characterized by long periods of steady precipitation in the form of rain, snow, or ice, and tend to produce less surface runoff and more recharge than the sumner storms because they have a longer duration and occasionally result in snowmelt (Cornell, Date Unknown). Land Use and Land Cover Land uses in SC include: agriculture, commercial, community services, industrial, open space, public services, recreation and entertainment, residential and vacant land. In 2007, 77.1 percent of the land in SC was used for residential purposes; 12.1 percent was vacant land; 6.2 percent for commercial; 1.4 percent for public services; I percent for conununity services; 0.8 percent for open space; 0.6 percent for industrial use; 0.5 percent for agricultural use; and 0.3 percent for recreation and entertainment use (Figure 4-2). ;i~ure 4-2.

The ten towns that make up SC vary in population size and density. Huntinbrton, Babylon, Smithtown, lslip, and Brookhaven, located in western SC, contain 91 percent of the County's populatiofi; yet only cover 62 percent of SC. The population density for western SC, in 2004, was 2,362 persons per square mile. In eastern SC, the population density is only 387 persons per square mile. Between 2004 and 2030, the population for SC is expected to increase by 19 percent (SC Planning Department, 2005). With the predicted population increase, residential land use will increase, while other land uses, such as vacant land and agriculture land, may decrease over time. Per the SC Planning Department, open space includes forests and agricultural land, undeveloped shorelines, undeveloped scenic lands, public and private parks, and preserves. It also includes water bodies, such as bays, lakes, and streams (SC Planning Department, 2005). In 2000, open space covered 23.4 percent of SC land (Long Island Index, 2004). With a rapid population growth, there is a demand for open space preservation, which will continue to support the tourist industry and water quality in SC (Newsday.com, 2007). In 1999, 83,000 acres of land in the five eastern SC towns was available for developm,ent. In western SC, there was far less land available for open space acquisitions, which makes it critical to acquire any such land before SC is completely built-out. With present funding levels, SC has the ability to purchase thousands of acres for open space preservation. But with the rapid population growth in SC, the ability to purchase and preserve open space will be diminished (SC Planning Department, 2005). Fi~cmre 4-3. Farmland and Open in SC SUFFOLK/..COUNTY NEW YORK FARMLAND I OPEN SPACE INVENTORY Source: }~ ip x~.~ ~.r ~fl-csearch.omrpDRdat N sest flblk.pdf In 2006, vacant, undeveloped land comprised 12 percent (69,740 acres) of land use in SC (SC Fire, Rescue and Emergency Services, 2006). Vacant land includes any undeveloped residential lots and land. It also includes abandoned agricultural land and rural land, vacant land in commercial areas, vacant land in industrial areas, urban renewal or slum clearance, and private and wild forest lands (SC Planning Department, 2004). Commercial properties comprise approximately 6.2 percent (36,013 acres) of SC in 2006 (SC Fire, Rescue and Emergency Services, 2006). These commercial properties include hotels and motels; camps, cottages, and bungalows; inns, lodges, rooming houses, etc.; dining establishments; motor vehicle DMA 2000 Hazard M~tigation Plan - Suffolk County, New York 4-6 DRAFT- September 2007 SECTION 4: COUNTY PROFILE services; retail services; retail services; bank and office buildings; entertainment businesses; sports assemblies; amusement facilities; indoor and out sports facilities; marinas; resort complexes; and professional associations (SC Planning Department, 2004). SC contains more than 22 million square feet of private office buildings, with a proposed 2.4 million of additional square feet to be added in the future. With such an extensive industrial, office, and tourist markets, a large number of hotels, motels, and bed and breakfast inns can be found throughout SC. Currently, SC has 304 hotels and motels, which contain over 11,600 roo~ns. In 2001, Long Island had a total of $42 billion in retail sales, which ranked third among the nation's 20 largest metropolitan areas. Due to SC's relatively high income, high retail sales levels, and population density, many retailers are drawn to the area. Shopping centers total 37 million square feet, with 8 million square feet of retail space in downtown centers. In 2006, industrial properties comprised only 0.6 percent (3,209 acres) of land use in SC (SC Fire, Rescue and Emergency Services, 2006). Industrial properties include storage, warehouse and distribution facilities; gasoline, fuel, oil, liquid petroleum storage and/or distribution; bottled gas, natural gas facilities; grain and feed elevators, mixers, sales, outlets; lumber yards, sawmills; coal yards, bins; cold storage facilities; trucking terminals; piers, wharves, docks, and related facilities; junkyards; manufacturing and processing; mining and quarrying; and industrial product pipelines. The largest industrial park in SC is the Hauppauge Industrial park in Happauge. It encompasses 1,400 acres and 14 million square feet in size (SC Economic Development and Workforce Housing, 2000). This industrial park is home to 1,300 businesses and 55,000 employees, making it the largest such complex east of the Mississippi River and the second largest in the United States (Canavor, 2003). In 2006, agricultural land currently made up 0.5 percent (2,870 acres) of SC's land use (SC Fire, Rescue and Emergency Services, 2006). This percentage includes any productive agricultural vacant land, livestock and products, field crops, truck crops, orchard crops, nursery and greenhouses, and specialty ' farms (SC Planning Department, 2004). In 2002, SC was the leading agriculture-producing county in NYS, with total sales of $201 million, which is a 9.7 percent increase since 1997. The leading products sold included nursery and greenhouse, vegetables, poultry and eggs, fruits and nuts, and aquaculture (Figure 4-4) (NY Agricultural Statistics Service, 2003). :igure 4-4. Leading Agricultural Products in SC for 2002 Leading Agricultural Products Percent of Total Aquaculture 3.8% Nursery & greenhouse 71.1% Source: NY Agricultural Statistics Service, 2003 Even though SC's agriculture sales have increased, SC has experienced a decrease in total farm acreage. In 2002, 651 farms (with 34,127 acres) were identified by the USDA, compared to 725 farms (with 35,858 acres) in 1997 (Office of the State Comptroller, 2006). Farmland acreage in SC is decreasing by DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-7 DRAFT - September 2007 SECTION 4: COUNTY PROFILE 1,400 acres each year, due to population growth and demands for residential space (SC Planning Department, 2005). Land Use Trends In NYS, land use regulatory authority is vested in towns,, villages, and cities. However, many development and preservation issues transcend local political boundaries. DMA 2000 requires that communities consider land use trends, which can impact the need for, and priority of, mitigation options over time. Land use trends can significantly impact exposure and vulnerability to various hazards. For example, significant new development in a hazard area increases the building stock and population exposed to that hazard. This mitigation plan provides a general overview of population and land uses and types of development occurring within the study area. An understanding of these development trends can assist in p'lanning for further development and ensuring that appropriate mitigation, planning and preparedness measures are in place to protect human health and community infrastructure. According to the Draft Generic Environmental Impact Statement (DGEIS) NYS for the Statewide Wireless Network (SWN), the largest communities in SC are Huntington Station, West Babylon, Centereach, Brentwood and Central Islip. Most commercial and industrial development is concentrated near North Amityville, Deer Park, and Ronkonkoma with considerable development along the Long Island Expressway in communities such as Melville and Hauppauge. There are a number of wetland areas and significant water bodies include the Atlantic Ocean, Long Island Sound, Great South Bay, and Great Peconic Bay. The largest wetland areas are in the Connetquot River State Park Preserve, along the Camans River, in Makamah County Nature Preserve and in Conscience Point WvVR. According to the DGEIS, the "Town of Hempstead and the Village of Southampton have assumed jurisdiction over local freshwater wetlands....Tidal wetlands such as salt marshes can be found across Long Island in the north and south shore embayments and in the Peconic Estuary at Bayshore, Long Island to 2 feet at Montauk Point and Plum Gut in eastern Long Island. Tidal ranges differ among these areas, ranging form 0.5 feet at Montauk Point and Plum Gut in eastern Long Island, to approximately 6 feet at Port Jefferson on Long Island's North shore. Because of these variations in tidal regime, salt marsh communities in this area differ, particularly in terms of vegetation." The highest density forest area is located in the Town of Southampton and east of Sag Harbor. Agricultural land use is greatest in the Town of Riverhead and around Bridgehampton. Barren land is found on thc barrier island on the southern shore and near Middle Island which is a community within the town of Brookhaven. In 1993. NYS legislature created the Long Island South Shore Estuary Reserve Council which adopted the Long Island South Shore Estuary Reserve Comprehensive Management Plan. This plan provides a blueprint for the long-term health of the Reserve's bays and tributaries, tidal wetlands, and wildlife, tourism and economy. Similarly, the legislature created the Long Island Sound Coastal Advisory Commission which prepared the Long Island Sound Coastal Management Program in 1999. Land usc is indicated for industrial and commercial, residential, co]mnercial, institutional, transportation, and agricuhural uses as well as vacant land. According to the December 1982 publication of the Quantification and Analysis of Land Use for Nassau and Suffolk Counties, the amount of vacant land at that time was a major element in the projection of future development. In SC, the town with the greatest amount of land used for low density housing was the Town of Huntington. The greatest amount of medium density residential development (one half to quarter acre lots) was in the towns of Brookhaven DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-8 DRAFT - September 2007 SECTION 4: COUNTY PROFILE and lslip. With respect to commercial development, the town with the largest area, Brookhaven, had almost 4,000 acres of land used for commercial purposes, although this represented only 2.5% of the total area. Shelter Island, the smallest town, had less than 100 acres of cmmnercial property which accounted for 1.1% of the total area. Industrial land included mining and low intensity development and was most prevalent in the town of Brookhaven followed by Huntington which had over 1,600 acres in industrial use. Riverhead, Shelter Islan& Southampton, and S0uthold each had less than 1.0% of land used for industrial purposes. The towns with the largest institutional land uses included Brookhaven, lslip, and Huntington. Four towns had over 5~000 acres of agricultural land use. These are Riverhead, Southampton, Brookhaven, and Southold. Towns with the most available vacant land were Brookhaven, Southampton (each exceeding 60,000 acres), East Hampton, and Southampton (Long Island Regional Planning Board, 1982). SC has more than 22 million square feet of private office buildings and 85 million square feet of industrial buildings. The tourist industry supports over 11,000 rooms in the lodging industry. Shopping centers account for approximately 37 million square feet with the downtown centers having 8 million square feet of retail space (SC Planning Department, 2005). The County has over 70,000 acres of parkland and approximately 1,000 miles of shoreline which supports tourism and recreation. There are more than 80 golf courses located in SC. In the past decade three major stadiums were constructed in SC including a 6,000 seat baseball stadium, a $25 million sports arena at Stony Brook campus, and a new 87~000 student activity center at Dowling College. In addition a 42,000 square foot aquarium is located in Riverhead. Other major development activity includes a proposed aquarium for Brentwood, a 200,000 square foot astronomy museum, new multiplex theatres, and a new mixed use community on a 460 acre portion of the Pilgrim State Psychiatric Center (SC Department of Planning, 2005). Figures 4-5 and 4-6 show the trend toward increased residential and industrial land use and a decrease in vacant land. :i~*ure 4-5.

Agricultural Land Trends According to the New York Agricultural Statistics Service, SC Farm Statistics, (01-05) there were 34,000 acres in farms in SC in 2003, which represents six percent of the county's total acreage. This was comprised of 645 farms averaging 53 acres per farm and resulted in a ranking for SC of 50th in NYS for land in farms and 27th in the state for land in farms. Agricultural land use over time is summarized in Table 4-2 and Figure 4-7.

Leadin~ Al~ricultural Products in SC for Land in Farms Source: NY Agricultural Statistics Service, 2003 2002 The trend during the past forty years is towards diminishing amounts of farmland in SC. This change in land use can be seen in the above pie charts that indicate that during the period of 1981 to 2000, residential land use has increased and the amount of land designated as farmland has decreased. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-11 DRAFT- September 2007 SECTION 4: COUNTY PROFILE POPULATION AND DEMOGRAPHICS According to the 2000 U.S. Census, SC had a population of 1,419,369 people. This is in exact agreement with the data included in HAZUS-MH which is based on the 2000 Census data. Table 4-3 presents the population statistics for the County based on the 2000 Census data. While it is recognized that the population of SC has increased significantly, and that this growth is not geographically uniform throughout the County, it is believed that the default population data within HAZUS-MH is sufficient and appropriate to support the risk assessment and mitigation planning efforts of this project. Further, considerations of long-term growth and seasonal population fluctuations have been addressed, as detailed in later parts of this subsection. DMA 2000 requires that HMPs consider socially vulnerable populations. These populations can be more susceptible to hazard events, based on a number of factors including their physical and financial ability to react or respond during a hazard and the location and construction quality of their housing. This HMP considers two socially vulnerable population groups, (1) the elderly (persons. over the age of 65) and (2) low-income (household annual income below $20,000 per year). Table 4-3.

Since data regarding the seasonal population increase is difficult to obtain, the SC Planning Depa~nent has estimated peak seasonal population based on available data. The SC Planning Department has calculated these estimates for all eastern SC communities and other selected communities. Eastern SC is comprised of the towns of Riverhead, Southold, Shelter Island, Southampton, and East Hampton. It is estimated that the population in eastern SC more than doubles during the summer season, increasing the year-round figure of 129,000 to 337,000 during the peak season (July-August) (an increase of 208,000 or 161.2%). The five eastern towns of SC together have approximately 30,000 seasonal homes, which add approximately 136,000 seasonal residents to the year-round population. In addition, seasonal guests in year round homes are estimated to total 44,000; campers total 4,800; and lodging occupants total 21,000 at peak. The overall seasonal population adds more than 207,000 to the year round population of eastern SC. The seasonal increases differ dramatically among the five eastern towns. In East Hampton, the peak seasonal population is estimated to be 4.5 times as large as the year-round population. East Hampton's population increases 351% from 20,000 to 91,000. This percentage increase is the largest of the five eastern SC towns. The increase is the most dramatic in Montauk, which has more seasonal homes and vastly more lodging rooms than any other single cormnunity. Shelter Island's seasonal percentage increase is the second largest, at 23.6%. The Town of East Hampton, with its large number of seasonal homes, increases in population by an estimated 351% from 20,347 to 91,768. The North Fork (which includes the towns of Southhold and Riverhead) has relatively fewer seasonal homes, so the estimated increases are not as dramatic. In Southold Town, the population increases by 133% from 21,015 to 49,052. In Riverhead, which is becoming somewhat more of a year- round community, the population increased 45% from 28,862 to 41,951 during peak seasonal times. Seasonal population estimates were also prepared for Fire Island and selected other Nassau-Suffolk communities. The most dramatic increase of any up-island area occurs in Fire Island, which has 323 year- round residents and an estimated 17,000 people at peak seasonal times. Other significant increases occur in the Fire Island incorporated villages of Ocean Beach and Saltaire. Other Nassau-Suffolk communities, such as Long Beach, Mastic Beach, and Rocky Point contain some seasonal homes. However, since these communities are primarily year-round in nature, some of the additional seasonal population in those communities is offset by year round residents vacationing elsewhere during those same peak times. In most communities, seasonal population results primarily from seasonal homes. This is particularly true in such communities as Bridgehampton, North Sea, Sagaponack, Fishers Island, and Fire Island. In Montauk, however, motels account for much of the seasonal population. In other conununities, seasonal guests in year-round homes comprise much of the seasonal population. Long Island's seasonal home concentrations continue to move eastward, as former seasonal homes in the western portions of Long Island have converted to year-round use. The proportion of Long Island's seasonal homes located in the five eastern towns continues to increase, and the number of seasonal homes in eastern SC has risen dramatically during the past 30 years. In addition, most of the original seasonal DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-35 DRAFT - September 2007 SECTION 4: COUNTY PROFILE homes in Nassau County and western SC have converted to year-round use. As recently as 1970, significant seasonal home concentrations existed in Long Beach, Atlantic Beach, Ronkonkoma, Sound Beach, Rocky Point, Wading River, Shirley, and Mastic Beach. By 1990, the seasonal home concentrations in these cormnunities had become much less significant.

Year Round and Seasonal Population Trends This section discusses the year round and seasonal population trends as a basis for estimating future changes impact the study area and its exposure to various hazards. This information provides a basis for making decisions on the type of mitigation approaches to consider and the locations in which these approaches should be applied. This information can also be used to support planning decisions regarding future development in vulnerable areas. Planning outcomes (for example, hazard analyses and proposed mitigation activities) should be incorporated into the individual town master plans, the County Comprehensive Emergency Management Plan, and a future SC Comprehensive Plan if possible. (According to the report entitled, "A Review of Selected Growth and Development Areas, SC, New York", the development of a county comprehensive plan is encouraged.) This section presents the current and projected population data for the SC Multi-Jurisdictional Study Area and housing trends from 1970 to 2000. Trend data available from the SC Planning Department has been summarized for eastern SC and western SC; however, western SC data was only available for 2000. This data has been supplemented by the Long Island Power Authority (LIPA) estimated data for the years of 2004 and 2005 (Figures 4-29 through 4-34). This information is provided graphically in Figures 4-29 through 4-34 with supplemental trend estimates for 2004 and 2005 from the LIPA 2005 Long Island Population Survey (which includes western SC jurisdictions).LIPA estimates the population for SC on January 1, 2005, at 1,483,396 persons. This total is 15,971 above that reported in the 2004 Population Survey. All of the County's ten towns experienced population gains during this 1-year period. The Town of Brookhaven accounted for 7,153 of the County's increase to lead all towns in numerical growth and remain SC's most populous town with an estimated 479,578 residents. Huntington, with an estimated population of 201,496 grew by 2,128 persons, lslip, SC's second most populous town added 1,745 persons and now totals 331,002. Fourth in DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-36 DRAFT - September 2007 SECTION 4: COUNTY PROFILE growth is Babylon which added 1,383 residents. The Town of Riverhead's population of 32,028 is l,119 above 2004 estimate. Southmnpton increased by 905 and Smithtown increased by 822n. Next are Southold's increase of 350 and East Hampton's 323 person increase. Lastly, Shelter Island, SC's smallest town, added 43 residents to total 2,439. The five western SC municipalities, which include .Huntington, Babylon, Islip, Smithtown, and Brookhaven, experienced a net increase of 13,231 persons (from 2004 to 2005). These municipalities are now estimated to have a combined population of 1,346,753 persons. The County's five eastern municipalities, which include Riverhead, Southampton, Southold, East Hampton, and Shelter Island, added 2,740 persons. The combined population of the five eastern towns is estimated to be 136,643 persons as of January 1, 2005.

LIPA estimated SC's 2004 population to be 1,467,000 persons, which is a 3.4% increase from the 2000 Census population of 1,419,369. From 1990 to 2000, SC experienced a 7.4% (97,505 persons) population increase. Between 1980 and 1990, the population of SC increased by 2.9% (36,000 persons), according to the U.S. Census. SC's population is projected to continue to increase moderately over the next twenty years. Between 2004 and 2030, the County's population is projected to increase by 19%. Of SC's ten towns, Riverhead is expected to increase by the largest percentage, followed in order by the Southampton, Southold, East Halnpton. Shelter Island, and Brookhaven. The largest numerical increase is expected in the Brookhaven ( I 13,000). Saturation population is the population which can be expected if all available land were to be developed according to existing zoning. The SC Planning Department uses this to determine the future population for the County. It is estimated that SC's saturation population is 1.75 million persons, and may be approached starting around the year 2030. The saturation population figure represents a 19% increase over thc 21104 population figure for the County. According to the SC Planning Department, in recent decades, the County's projected saturation population has declined significantly. In 1962, the saturation population was projected to be 3.4 million people iu SC. Due to zoning changes, land preservation efforts, and lower average household sizes, a much Ioxx er saturation population is now expected. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-40 DRAFT- September 2007 SECTION 4: COUNTY PROFILE GENERAL BUILDING STOCK The 2000 Census data identifies 469,299 households in SC. The Census data identifies 522,323 housing units in SC in 2000, an increase of 10.5% from 1990. Census defines household as all the persons who occupy a housing unit, and a housing unit as a house, an apartment, a mobile home, a group of rooms, or a single room that is occupied (or if vacant, is intended for occupancy) as separate living quarters. Therefore, you may have more than one household per housing unit. The median price ora single family home in SC was estimated at $185,200 by the 2000 U.S. Census. The data in HAZUS-MH estimates that there are 461,871 structures in SC, with a total building replacement value (structure and content) of greater than $210 billion. Approximately 99% of the buildings and 84% of the building stock structural value are associated with residential housing. Table 4-6 presents Building Stock Statistics by Occupancy Class for SC, based on HAZUS-MH provided data. Table 4-6.

Exposure value reflects the replacement cost for building structure and contents. Generally, contents for residential structures are valued at about 50 percent of the building's value. For conunercial facilities, the value of the content is generally about equal to the building's structural value. *Shelter Island indicated they have 50-60 commercial buildings in their town. The 2000 Census data identified that the majority of housing units (85.8%) in SC are single family detached or attached units. The 2002 U.S. Census Bureau's County Business Patterns data identified 45,532 business establishments employing 536,790 people in SC. The majority (62%) of these establishments employed between one and four employees. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-41 DRAFT - September 2007 SECTION 4: COUNTY PROFILE Figure 4-35 through Figure 4-55 show the distribution and exposure density of residential, commercial and industrial buildings in SC organized by participating municipality. Exposure density is the dollar value of structures per unit area, including building content value. Generally, contents for residential structures are valued at about 50 percent of the building's value. For commercial facilities, the value of the content is generally about equal to the building's structural value. The densities are shown in units of $1,000,000 (SM) per square mile. HAZUS-MH indicates there are 5,001 mobile homes located in SC, which compares relatively closely with 2000 U.S. Census data that indicates 5,374 mobile homes in SC. Manufactured homes include trailer homes and trailer homes can be more susceptible to hazard event damages. Limited County-wide information was received regarding the location of mobile homes in all jurisdictions. Therefore, Figure 4- 56 illustrates the distribution of mobile homes in SC, a subset of the residential building class in HAZUS- MH. Viewing exposure distribution maps suclx as Figures 4-35 through 4-55 can assist communities in visualizing areas of high exposure and in evaluating aspects of the study area in relation to the specific hazard risks.

According to the Shelter Island Comprehensive Plan, its two private air strips do not accommodate commercial service and only a small amount of the population accesses the island via air. The North and South Ferries provide the main transportation link to Shelter Island. North Ferry runs from Shelter Island Heights to Greenport in the Town of Southold and South Ferry runs from Shelter lsland to North Haven in the Town of Southampton. These are private ferries that are publicly regulated; these firms transport both passengers and automobiles. Ferry traffic increased 40% from 1982 to 1992, transporting nearly one million automobiles on/off the island in 1992 (Shelter Island, 1994). Because Shelter Island relies so heavily on marine transportation, anchorages and dockage were also identified as crucial to their transportation inventory (Table 4-22). lable 4-22. and Docka .~ for Shelter Island Coecles Harbor Anchorage Shelter Island West Neck Anchorage Shelter Island Congon's Creek Town Dock Shelter Island Dering Harbor Town Dock Shelter Island Source: Planning Committee; HAZUS-MH (2005) NA $1,286,200 NA NA $1,286,200 NA NA $1,286,200 NA NA $1,286,200 NA l,ifeline UtiliD~ Systems Lifelines include utility services and infrastructure that provide water, power, and other necessary services to residents. Due to heightened security concerns, some location information for lifelines is not provided in the plan, although the number of facilities and their general location is considered (as data are available). Additionally, because the majority of power supply lines are privately held, this information is generally difficult to obtain and is not for public release. However, consideration of the utilities in the area is presented below to support the risk assessment in Section 5. Potable Water Supply Long Island's groundwater system is a federally-designated "sole source" aquifer. Additionally, the area is also identified as a Primary Water Supply Aquifer by NYS Department of Health (1981) and NYS Department of Environmental Conservation (1987) (EPA, 2007). EPA defines a sole-source aquifer as an aquifer that supplies 50-percent or more of the drinking water for an area. The recharge in the area is 990 million gallons per day (MGD). The total capacity of the aquifers underlying SC is about 70 trillion gallons. Most of this water is returned to the aquifer with consumptive loss estimated at 95 MGD. The consumptive loss is through pumping, personal use, sewage systems, marine discharges and cxapotranspiration associated with irrigation and lawn sprinkling (Earth Science Educational Resource ('enter. Date Unknown). Thc SC Water Authority (SCWA) services a majority of SC's population. According to the 2007 Annual Drinking Water Quality Report, SCWA serves over l.l million customers in the County. SCWA maintains 621 wells that pump water from the Long Island Aquifer (SCWA, 2007). In addition to SWCA~ a portion of the Town of Babylon (7,500 people) is serviced by the East Farmingdale Water District (Feitner and Hanse, 2006; LI Water Conference, accessed online 2007). The Riverhead Water District services the Town of Riverhead. The Riverhead Water District maintains thirteen (13) wells that arc drilled into the Glacial and Magothy aquifers (Riverhead Water District, 2006). The Town of Huntington is served by SCWA, Dix Hills Water District, Greenlawn Water District, and South Huntington Water District. The Town of Smithtown is served by SCWA, Brentwood Water District, St. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-111 DRAFT- September 2007 SECTION 4: COUNTY PROFILE James Water District, and Smithtown Water District (L1 Water Conference, accessed online 2007). There are three public water supply systems on Shelter Island: Shelter Island Heights, West Neck (approximately 60 home) and Dering Harbor (approximately 20 homes). The remainder of the populati6n relies upon "on-site facilities" (Shelter lsland, 1994: Card, 2007). There are approximately 77,000 individual private wells serving over 200,000 people in SC. The SC Department of Health Services operates an extensive water testing program to help residents with private wells determine the quality of their drinking (SC Department of Health Services, accessed online 2007). Wastewater Facilities According to SC GIS data, there are 25 sewer districts in SC. Table 4-23 lists the wastewater treatment facilities in the County and Table 4-24 lists the wastewater pumps or lift stations in the County. The wastewater treatment facilities' replacement value is the default value provided in HAZUS-MH. This default value may be overestimating the replacement cost for several of the smaller plants listed. Please note seve,ral of the pump/lift stations have identical names (e.g., there are ftve Pump Station #1 's in the Town of Brookhaven). Although they are assigned the same name, each station has a different physical address. In Sewer District 3, in southwestern SC, the SC Department of Public Works maintains a 72-inch ocean outfall that disposes treated sewage from the Towns of Babylon and Islip 2.5 miles into the Atlantic Ocean. The outfall route is from Bergen Point (Fleet Point) through Cedar Island to the ocean and its construction is vulnerable to storm activity and coastal erosion (Wright, 2007). The original construction of the outfall had cover over the pope at the shoreline approximately 17 feet. Storms have reduced that cover to 8 feet at the shoreline and less to the south. In 1992, a project was implemented ($3.5 million) to install 700 feet of sheeting with a rehabilitated cathodic protection system at the shoreline. Table 4-23.

DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 4-131 DRAFT- September 2007 SECTION 5: RISK ASSESSMENT SECTION 5: RISK ASSESSMENT 5.1 METHODOLOGY AND TOOLS This section describes the methodology and tools used to support the risk assessment process. Melhodolugy The risk assessment process used for this Plan is consistent with the process and steps presented in FEMA 386-2, State and Local Mitigation Planning How-to-Guide, Understanding Your Risks - Identifying Hazards and Estimating Losses (FEMA 2001 ). This process identifies and profiles the hazards of concern and assesses the vulnerability of assets (population, structures, critical facilities and the economy) at risk in the community. A risk assessment provides a foundation for the community's decision makers to evaluate ,mitigation measures that can help reduce the impacts ora hazard when one occurs (Section 6 of this plan). Step 1: The first step of the risk assessment process is to identify the hazards of concern. FEMA's current regulations only require an evaluation of natural hazards. Natural hazards are natural events that threaten lives, property, and many other assets. Often, natural hazards can be predicted, where they tend to occur repeatedly in the same geographical locations because they are related to weather patterns or physical characteristics of an area. Step 2: The next step of the risk assessment is to prepare a profile for each hazard of concern. These profiles assist communities in evaluating and comparing the hazards that can impact their area. Each type of hazard has unique characteristics that vary from event to event. That is, the impacts associated with a specific hazard can vary depending on the magnitude and location of each event (a hazard event is a specific, uninterrupted occurrence of a particular type of hazard). Further, the probability of occurrence of a hazard in a given location impacts the priority assigned to that hazard. Finally, each hazard will impact different communities in different ways, based on geography, local development, population distribution, age of buildings, and mitigation measures already implemented. Steps 3 and 4: To understand risk, a community must evaluate what assets it possesses and which assets are exposed or vulnerable to the identified hazards of concern. Hazard profile information combined with data regarding population, demographics, general building stock, and critical facilities at risk, located in Section 4, prepares the community to develop risk scenarios and estimate potential damages and losses for each hazard. Tools To address the requirements of DMA 2000 and better understand potential vulnerability and losses associated with hazards of concern, SC used standardized tools, combined with local, state, and federal data and expertise to conduct the risk assessment. Two standardized tools used to support the risk assessment are introduced below. Hazard Identification and Risk Assessment (HIRA) HIRA-NY is an interactive spreadsheet application designed to support communities in evaluating hazards that could be a concern. This tool was developed by NYSEMO to support consistent DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.1-1 DRAFT - September 2007 SECTION 5.1: RISK ASSESSMENT - METHODOLOGY AND TOOLS identification and ranking of hazards across the State. The program leads the user through a series of four steps: ( 1 ) Identify the Hazards, (2) Profile Hazard Events~ (3) Inventory Assets, and (4) Estimate Losses. On October 11, 2006, NYSEMO led a demonstration and training session on use of HIRA-NY to the Planning Committee. The planning process for this effort used Step I of HIRA-NY to identify and determine the prevalent hazards of concern pertaining to the County as a whole, and each participating jurisdiction. Hazards U.S.- Multi-Hazard (HAZUS-MH) In 1997, FEMA developed a standardized model for estimating losses caused by earthquakes, known as Hazards U.S. or HAZUS. HAZUS'was developed in response to the need for more effective national-, state-, and community-level planning and the need to identify areas that face the highest risk and potential for loss. HAZUS was expanded into a multi-hazard methodology, HAZUS-MH with new models for estimating potential losses from wind.(hurricanes) and flood (riverine and coastal) hazards. HAZUS-MH is a Geographic Information System (GIS)-based software tool that applies engineering and scientific risk calculations that have been developed by hazard and information technology experts to provide defensible damage and loss estimates. These methodologies are accepted by FEMA and provide a consistent framework for assessing risk across a variety of hazards. The G1S framework also supports the evaluation of hazards and assessment of inventory and loss estimates for these hazards. HAZUS-MH uses GIS technology to produce detailed maps and analytical reports that estimate a community's direct physical damage to building stock, critical facilities, transportation systems and utility systems. To generate this information, HAZUS-MH uses default HAZUS-MH provided data for inventory, vulnerability, and hazards; this default data can be supplemented with local data to provide a more refined analysis. Damage reports can include induced damage (inundation, fire, threats posed by hazardous materials and debris) and direct economic and social losses (casualties, shelter requirements, and economic impact) depending on the hazard and available local data. HAZUS-MH's open data architecture can be used to manage community GIS data in a central location. The use of this software also promotes consistency of data output now and in the future and standardization of data collection and storage. The guidance Using HAZUS-MH for Risk Assessment: How-to Guide (FEMA 433) was used to support the application of HAZUS-MH for this risk assessment and plan. More information on HAZUS- MH is available at h~p:'r/www.fema.gox/plau/pre~ent/hazus/iudex.shtm. Two methodologies were used to assess potential exposure and losses associated with hazards of concern for SC. Both approaches used HAZUS-MH to some extent and are summarized below: HAZUS-MH was customized and applied using HAZUS-MH software and associated tools to estimate losses associated with the flood and hurricane hazards. For the flood hazard, the damage functions in HAZUS-MH Flood Wizard were replaced with the coastal damage functions from HAZUS-MH MR1 to model the coastal flooding hazard. For hurricanes, currently HAZUS-MH only analyzes the flood and wind models separately, producing independent results. However, it is recognized that hurricanes cause both wind and storm surge related damage. An attempt was made to combine these hazards to produce wind and storm surge loss estimates for the hurricane hazard using HAZUS-MH. Further detail on this methodology is located in Section 5 in the hurricane profile. In addition, potential losses calculated using the HAZUS-MH hurricane model (wind only) are integrated and presented for other high wind events such as Nor'Easters and severe storms.) DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.1-2 DRAFT- September 2007 SECTION 5.1: RISK ASSESSMENT - METHODOLOGY AND TOOLS HAZUS-MH support was used to evaluate other hazards, as feasible. For many of the hazards evaluated in this risk assessment, historic data are not adequate to model future losses at this time. However, HAZUS-MH can map hazard areas and calculate exposures if geographic information on the locations of the hazards and inventory data are available. For some of the other hazards of concern, areas and inventory susceptible to specific hazards were mapped and exposure was evaluated to help guide mitigation efforts discussed in Section 6. For other hazards, a qualitative analysis was conducted using the best available data and professional judgment. For this risk assessment, the loss estimates, exposure assessments, and hazard-specific vulnerability evaluations rely on the best available data and methodologies. Uncertainties are inherent in any loss estimation methodology and arise in part from incomplete scientific knowledge concerning natural hazards and their affects on the built environment. Uncertainties also result from the following: 1 ) Approximations and simplifications necessary to conduct such a study 2) Incomplete or dated inventory, demographic, or economic parameter data 3) The unique nature, geographic extent, and severity of each hazard 4) Mitigation measures already employed by SC and the amount of advance notice residents have to prepare for a specific hazard event These factors can result in a range of uncertainty in loss estimates, possibly by a factor of two or more. Therefore, potential exposure and loss estimates are approximate. These results do not predict precise results and should be used to understand relative risk. Over the long term, SC will collect additional data to assist in developing refined estimates of vulnera6ilities to natural hazards. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.1-3 DRAFT - September 2007 SECTION 5.2: RISK ASSESSMENT - IDENTIFICATION OF HAZARDS OF CONCERN 5.2 IDENTIFICATION OF HAZARDS OF CONCERN To provide a strong foundation for mitigation actions considered in Section 6, Suffolk County (SC) focused on considering a full range of hazards that could impact the area, and then identified and ranked those hazards that presented the greatest concern. The hazard of concern identification process incorporated input from the County and participating jurisdictions; review of the New York State (NYS) Basic HMP; research and local, state, and federal information on the frequency, magnitude, and costs associated with the various hazards that Hazards of Concern are those hazards that are considered most likely to impact a community. These are identified using available data and Intel knnwl~dn~ have previously, or could feasibly, impact the region; and qualitative or anecdotal information regarding natural hazards and the perceived vulnerability of the study area's assets to them. Table 5-1 documents the process of identifying the natural hazards of concern for further profiling and evaluation. For the purposes of this planning effort, the Planning Committee chose to group some hazards together, based on the similarity of hazard events, their typical concurrence or their impacts, consideration of how hazards have been grouped in FEMA guidance documents (FEMA 386-2, "Understanding Your Risks, Identifying Hazards and Estimating Losses; FEMA's "Multi-Hazard Identification and Risk Assessment - The Cornerstone of the National Mitigation'Strategy"), and consideration of hazard grouping in the NYS Basic HMP. Tropical cyclones (hurricanes, tropical storms and tropical depressions) shall be grouped under the "Hurricane" hazard. Due to the great amount of post-Katrina media attention on the exposure and risk of Long Island to hurricanes, the planning committee felt that having hurricanes identified separately from extra-tropical storms and other severe storm events was prudent. Extra-tropical cyclones (Nor'Easters and severe winter low-pressure systems) shall be grouped under the "Nor'Easter" hazard. The "Severe Storm" hazard includes windstorms that often entail a variety of other influencing weather conditions including thunderstorms~ hail, and tornados. Tropical and extra-tropical cyclones, sometimes grouped together under a coastal storms hazard (FEMA 386-2), are being grouped in separate hazard categories as explained above. The "Flooding" hazard includes riverine flooding, flash flooding, urban flooding (local drainage problems), and coastal flooding (including storm surges). Inclusion of the various forms of flooding under a general "Flood" hazard is consistent with that used in FEMA's "Multi-Hazard Identification and Risk Assessment" guidance. The "Severe Winter Storm" hazard includes heavy snowfall, blizzards, and ice storms. This grouping is consistent with that used in the NYS Basic HMP.

DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.2-10 DRAFT- September 2007 SECTION 5.3: RISK ASSESSMENT - HAZARD RANKING METHODOLOGY 5.3 HAZARD RANKING METHODOLOGY The hazards of concern are ranked for SC as a whole to describe their probability of occurrence and their impact on population, property (general building stock including critical facilities) and the economy. Each participating Town or Village may have differing degrees of risk exposure and vulnerability compared to the County as a whole: therefore each Town/Village ranked the degree of risk to each hazard as it pertains to their community using the same methodology as applied to the County-wide ranking. This assures consistency in the overall ranking of risk process. The hazard ranking for each participating Town or Village can be found in their jurisdictional annex in Volume 11 of this Plan. This section describes factors that influence the ranking including the probability of occurrence and impact; it also presents the ranking process and outcome. Estimates of risk for Suffolk County were developed using methodologies promoted by FEMA's hazard mitigation planning guidance and generated by FEMA's HAZUS-MH risk assessment tool. Probability of Occurrence The probability of occurrence is an estimate-of how often or frequent a hazard event occurs. A review of historic events assists with this determination. Each hazard of concern is rated in accordance with the numerical ratings and definitions in Table 5-2. These definitions are consistent with FEMA's Multi- Hazard Identification and Risk Assessment report (FEMA, 1997). Table 5-2. Probabilit, of Occurrence Rankin Factors Hazard event that occurs less frequently than once in 1,000 years. 0 None (>10'3/yr) / Hazard event is not likely to occur Hazard event that occurs from once in 100 years to once in 1,000 years 1 Rare ( lO-2/yr to 10'3/yr) Hazard event that occurs from once in 10 years to once in 100 years 2 Occasional (10'~/yr to 10-2/yr) 3 Frequent Hazard event that occurs more frequently than once in 10 years (>10'~/yr) Impact The impact of each hazard is considered in three categories: impact on population, impact on property (general building stock including critical facilities), and impact on the economy..Based on documented historic losses and a subjective assessment by the Planning Committee, an impact rating of high, medium, or low is assigned with a corresponding numeric value for each hazard of concern, in addition, a weighting factor is assigned to each impact category: three (3) for population, two (2) for property, and one (1) for economy. This gives the impact on population the greatest weight in evaluating the impact of a hazard. Table 5-3 presents the numerical rating, weighted factor and description for each impact category: people, property and the economy. Please refer to Appendix F for a more detailed description of how the values were assigned.

Risk Ranking Value The risk ranking for each hazard is then calculated by multiplying the numerical value for probability of occurrence by the sum of the numerical values for impact. The equation is as follows: Impact Value (1, 2, or 3) X Impact Value (6 to 18) = Hazard Ranking Value. Based on the total for each hazard, a priority ranking is assigned to each hazard of concern (high, medium, or low). HAZARD RANKING RESULTS Using the process described above, the risk ranking for the identified hazards of concern was determined for the County. Based on the combined risk values for probability of occurrence and impact to the County, a priority ranking of "high", "medium" or "low" risk was assigned. The hazard ranking for the County, from high to low risk, is summarized below: The following tables present the step-wise process for the ranking. Table 5-4 shows the probability ranking assigned for likelihood of occurrence for each hazard.

ItAZARD PROFII,E This section provides profile information including description, location and extent, previous occurrences and losses, and the probability of future occurrences. Description Coastal storms that affect Long Island fall into two general categories: hurricanes (tropical cyclones) and extratropical storms (midatlantic cycloneg, northeasters or Nor'Easters). Although both types of storms can cause a similar level of devastation to developed coastlines, they are vastly different with respect to origin and progression (Cashin Associates, 1994). Therefore, these tw¢o types of coastal storms are addressed as separate hazards within this HMP. Nor'Easters, named for the strong northeasterly winds that blow in ahead of these storms, are also categorized as a type of extratropical cyclone (mid-latitude storm, or Great Lake storm). A description of both Extatropical Cyclones and Nor'Easter is provided below. Extra-Tropical Cyclone: Extratropical cyclones, sometimes called mid-latitude cyclones, are a group of cyclones defined as synoptic scale, low pressure, weather systems that occur in the middle latitudes of the Earth. These storms have neither tropical nor polar characteristics and are connected with fronts and horizontal gradients in temperature and dew point otherwise known as "baroclinic zones". Extratropical cyclones are everyday weather phenomena which, along with anticyclones, drive the weather over much of the Earth. These cyclones produce impacts ranging from cloudiness and mild showers to heavy gales and thunderstorms. Tropical cyclones often transform into extratropical cyclones at the end of their tropical existence, usually between 30° and 40° latitude, where there is sufficient force from upper-level shortwave troughs riding the westerlies (weather systems moving west to east) for the process of extratropical transition to begin. A shortwave trough is a disturbance in the mid or upper part of the atmosphere which induces upward motion ahead of it. During an extratropical transition, a cyclone begins to tilt back into the colder air mass with height, and the cyclone's primary energy source converts from the release of latent heat from condensation (from thunderstorms near the center) to baroclinic processes (Canadian Hurricane Centre, 2003). Nor'Easter (abbreviated for Northeaster): A Nor'Easter is a macro-scale Extratropical storm whose winds come from the northeast, especially in the coastal areas of the Northeastern United States and Atlantic Canada. More specifically, it describes a low pressure area whose center of rotation is just off the coast and whose leading winds in the left forward quadrant rotate onto land from the northeast. Wind gusts associated with these storms can exceed hurricane forces in intensity. Unlike tropical cyclones that form in the tropics and have warm cores (including tropical depressions, tropical storms and hurricanes), Nor'Easters contain a cold core of low barometric pressure that forms in the mid-latitudes. Their strongest winds are close to the earth's surface and they often measure several hundred miles across. Nor'Easters may occur at any time of the year but are most common during the fall and winter months (September through April) (NYOEM, 2007). Nor'Easters can cause heavy snow, rain, gale force winds, and oversized waves (storm surge) that can cause beach erosion, coastal flooding, structural damage, power outages and unsafe human conditions. If a Nor'Easter cyclone stays just offshore, the results are much more devastating than if the cyclone meanders up the coast on an inland track. Nor'Easters that stay inland are generally weaker and only DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.1-1 DRAFT- September 2007 SECTION 5.4.1: RISK ASSESSMENT- NOR'EASTER cause strong wind and rain. Those that stay offshore can bring heavy snow, blizzards, ice, strong winds, high waves, and severe beach erosion. In these storms, the warmer air is aloft. Precipitation falling from this warm air moves into the colder air at the surface, causing crippling sleet or freezing rain. Ifa significant pressure drop occurs within a Nor'Easter, this change can turn a simple extratropical storm into what is known as a "bomb". ~'Bombs" are characterized by a pressure drop of at least 24 millibars within 24 hours (similar to a rapidly-intensifying hurricane). Even though "bombs" occasionally share some characteristics with hurricanes, the two storms have several differences. "Bombs" (being a type of Nor'Easter) are extratropical, and therefore, are associated with fronts, higher latitudes, and cold cores. They require strong upper-level winds, which would destroy a hurricane [Multi-Community Environmental Storm Observatory (MESO), 2002]. For the purpose of this HMP, only Nor'Easter events are being further discussed within this hazard profile, due to their significant historical impact on SC. Location and Extent Because SC is primarily surrounded by coastal waters, Nor'Easters affect the entire mitigation study area, particularly communities along the north and south shores of the County. Multiple sources document that SC has been impacted by many Nor'Easters. The county has felt the direct and indirect landward effects, including high winds, heavy rains, flash and coastal flooding, and beach erosion associated with several Nor'Easters. Though the occurrence of a Nor'Easter can be forecasted with some accuracy, predicting their impact is more complex. The extent (that is, magnitude, severity, or intensity) of a Nor'Easter can be categorized by the Dolan-Davis Nor'Easter Intensity Scale. In 1993, researchers Robert Davis and Robert Dolan created this Nor'Easter intensity scale, but it deals primarily with beach and coastal deterioration. This scale, presented as Table 5-8, categorizes or rates the intensity of Nor'Easters from 1 (weak) to 5 (extreme) based on a storm class rating that is based on an estimate of the potential beach erosion, dune erosion, overwash, and property damage expected from a Nor'Easter (MESO, 2002). Tuble 5-8.

In an article posted in the January 2002 issue of the Bulletin of the American Meteorological Society (BAMS), Dr. Zielinski explains: "My classification scheme allows forecasters and meteorologists to easil'y summarize the intensity of a winter storm by giving it an intensity index and placing it into its appropriate category on a I-5 scale. The potential impact of the storm can then be passed on to public service officials so they may make plans for precipitation amounts, particularly snow, snowfall rates, wind speeds, drifting potential, and the overall impact on schools, businesses, travelers, and coastal communities." In Zietinski's classification system, a second number reflecting forward speed is used together with a number that is based on intensity. The second number ranges between I and 5. A 5 would be the slowest moving and thus longest duration storm. For example, a storm's category might be 2.4, reflecting an intensity of 2 with the first digit and duration of 4 with the second (MESO, 2002). Zielinski has used his scale in a historical investigation of New England's climate. He has classified more than 70 storms of the past, including the Great Arctic Outbreak of 1899, the Blizzard of 1888, and other storms that are part of U.S. weather lore. A December 2000 storm was the most intense found in his study (Zielinski, 2003). Previous .Occurrences and Losses Nor'Easters frequently impact the County, because SC is surrounded by coastal waters to the north, east and south. Data provided by FEMA, NYSEMO and the NYS HMP on Presidential Declared Disasters identify six Presidential (DR)/Emergency (EM) Declarations associated with Nor'Easter events (with some of these event also listed as other types of hazards from different sources) (Table 5-9).

Long Island communities, such as Fire Island were decimated with over 100 homes destroyed from this event (Watson, 2006). The USACE indicated that this flooding event caused a total of 50 washovers and formed one new inlet at Westhampton Beach. On Fire Island, a total of 47 homes were destroyed and 75 were damaged resulting in property losses estimated in the millions. Twelve square miles of the mainland were inundated; under current development conditions, a recurrence of these flood stages would mean that approximately 4,500 structures would be inundated up to 6 feet in depth. As a result of this storm, the New York District of the USACE constructed emergency protective works throughout the study area ("Operation Five-High"). Assistance was provided to the local communities to in the removal of debris, and in the rebuilding of beaches and dunes. One of the first response actions of the Corps was to assist in the closure of the breach at Westhampton. In total, over 2 million cubic yards of material were used to rebuild over 23 miles of beaches and dunes in the study area (USACE, Date Unknown). According to SHELDUS, this event resulted in approximately $714,000 in property damages to the County. Another source indicates that the storm resulted in over 75 breaks (washovers) between Fire Island Inlet and Southampton. The largest breach was about 400 meters wide and occurred at Westhampton Beach. In the Moriches to Shinnecock Reach, large stretches of Dune Road and 46 houses were destroyed. A notable occurred at Shinnecock Inlet: the west side eroded and accretion occurred along the east side. President Eisenhower declared the south shore a disaster area eligible for Federal aid. Under authority of DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5,4.1-6 DRAFT - September 2007 SECTION 5.4.1: RISK ASSESSMENT - NOR'EASTER Public Law 875, the USACE performed engineering and construction of emergency shore protection and rehabilitation. Some 2,210,000 cubic yards of sand was pumped onto beaches, mostly from back bays (). Figure 5-1. March 8, 1962 Aerial Photos of SC South Shore Note: Aerial view of Moriches Inlet and Saltaire on March 8.1962 Source: (Historical Aerial Photos, Date Unknown) October 30-31, 1991 ("The Perfect Storm" or "Halloween Storm of 1991"): This storm was an unusual Nor'Easter which was extratropical. This storm also absorbed one hurricane, before it ultimately evolved into a small hurricane late in its life cycle. The unnamed hurricane of 1991 was the last tropical cyclone of the 1991 Atlantic hurricane season, and its fourth hurricane. By November 2, Atlantic Canada experienced the effects of this land-falling tropical storm. Damage totals neared $1 billion (1991 USD) and deaths climbed to 12 people. Most of the damage occurred while the storm was extratropical. The hurricane was the second costliest storm of the season, behind only Hurricane Bob, which caused $1.5 billion in damages (1991 USD, $2.1 billion 2005 USD) (Wikipedia, 2007). Damages totaled over $10 million throughout NYS and northern New Jersey as a result of this storm and the two states received the most damage to coastal sections since the Great Atlantic Hurricane of 1944. Homes, boats, roads, beaches and seawalls were destroyed; numerous boats were damaged or destroyed at their berths; and three boats sunk on Long Island Sound (all on board rescued). As provided by NOAA-NCDC, Figure 5-2 depicts the monster storm off the Eastern Seaboard (NCDC, 2004).

In this image, the storm was at its peak intensity. The storm became subtropical thifly hours later,just before the inner core of the storm developed into a topical storm and later an unnamed hurricane. The worst hit areas in SC included Westhampton, Ocean Beach, Southampton, Montauk, Smith Point, Southold, Fire Island, Babylon, East Hampton, Shelter Island and Orient Beach. This storm caused heavy flooding and severe erosion across Long island. A tidal surge with waves as high as 15 feet occurred in some places, engulfed the shores, sheered off sweeping stretches of beach from Montauk to Freeport, and punched holes in environmentally sensitive barrier beaches. This event appeared to be one of the top three erosion events in the area's history (Figure 5-3). It caused more beach erosion then other recent hurricanes at the time (such as Hurricanes Bob and Gloria). Restoration of the SC beaches was expected to cost considerable money. Senator Alfonse D'Amato estimated the damage at tens of millions of dollars (including damage to houses and barrier beaches) (Long Island Hurricane History, 2007). Damage to Townships, Villages and Hamlets in SC included, but were not limited to, the following: · Babylon: Gilgo Beach in Babylon scoured away. On the south shore of Babylon the water was so high at Gilgo Beach that it almost the covered tops of picnic tables. A layer of sand five-feet deep disappeared from Babylon Beaches. · Shelter Island: Tides 5 to 8 feet above normal flooded Ram Island causeways on Shelter Island causing an eroded Crescent Beach. Southold: Significant flooding in St. Jamesport at Peconic Bay. Orient Beach experienced significant damage, causing it to close for an extended period of time. The roadway to the beach was undermined and caved in and the park was completely flooded. The access road to Orient Beach State Park was severed in 10 places. This was on of the hardest hit beaches in Long Island. East Hampton: 150 feet of beach was lost at Napeague State Park. On the north side of Montauk, at mouth of Lake Montauk, water washed over Gosman's Dock. A 20-foot section of West Lake Drive collapsed from flood waters. In addition, 10 feet of bluff on each side of Montauk Lighthouse was carved out. At the Ocean Beach ferry terminal, the point where the dock ended DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4,1-8 DRAFT- September 2007 SECTION 5.4.1: RISK ASSESSMENT - NOR'EASTER and land began could not be identified due to the flood waters. A dozen propane tanks and an electric dryer floated among the debris. · Islip: Ocean Beach was found underwater. Islip was issued an evacuation order for Fire Island. · Southampton: Southampton was found underwater. In Westhamptom an Air National Guard helicopter from Westhampton, with 5 crew aboard, went missing after it went down in rough waters. The storm washed away several houses on Dune Road in Westhampton Beach. One of the hardest hit areas was Dune Road (Figure 5-4); the barrier beach was breached in two places, dozens of homes were destroyed, and thousands of feet of roadway were ruined. One house was turned 180 degrees on its foundation by a powerful wave. More than two dozen ocean front homes in Westhampton were destroyed and left as debris after 10 to 15 foot waves crashed over Dune Road along more then a mile long section. Many houses were buried in sand and debris. Between 1,500 and 2,000 feet of Dune Road were clearly washed away. · Fire Island: Four people in boats that were capsized by waves fell into the icy water and were admitted to hospitals to address hypothermia. Several 40-foot dunes on Fire Island were leveled. Multiple homes were destroyed (Figure 5-5). Raw sewage was reported leaching from cesspools and septic tanks in some areas of the Island and residents who use well water were urged to boil water (Long Island Hurricane History, 2007). ; Island, NY Caption: "Rider On The Storm: Winds Whip Ll.'s Coastal Areas, Flooding Roads, Homes and Beaches" (Photo taken in Babylon).

This winter storm, along ~vith a series of other less damaging storms between 1992 and 1993 (e.g. March 12-14, 1993 Nor'Easter), caused widespread physical problems, including extensive beach erosion, dune scarping and overwash, bluff erosion, flooding, significant structural damage, and the disruption of transportation, utilities, and essential services. This storm caused torrential rains, gusting winds, massive flooding, power outages, and property damage. Basements were flooded, trees and utility poles were downed, and traffic was snarled. This storm caused about $1 to $2 million in damages and other costs and caused 19 deaths throughout the northeastern U.S., which included Long Island, NY (Patchogue Village, 2006). It was identified as one of the worst Nor'Easters in four decades and one of worst coastal storms to hit Long Island. More than 100 homes on Long Island were destroyed and thousands more were damaged. Over $10 million in damages were reported to SC South Shore beaches, town'properties, and homes. The worst hit areas in SC included Babylon, Riverhead, Port Jefferson, L~ndenhurst, Sag Harbor, Shelter Island, Asharoken-Eatons Neck, Orient, Fire Island, Lloyd's Neck, Montauk, Lake Ronkonkoma, Westhampton, Mastic Beach, Amityville, Saltaire, Copiague, Wading River, Brookhaven, Setauket, Smithtown, and Southampton. This two-day Nor'Easter tore vast amounts of sand from the South Shore beaches, ravaged the North Shore, and carved a new inlet through Dune Road in Westhampton (Mintz, 2004). Many state parks were closed including Captree, Jones Beach, Robert Moses, Orient Beach, and the Planting Fields Arboretum. About 448,000 Long Island homes lost power at one time or another during the storm (40% of LILCO customers) (Figure 5-6). From Lloyd Harbor to Wading River, cars were submerged on flooded roadways and high voltage wires snapped. As tides averaged 5 to 15 feet above normal, some areas remained inaccessible, 60,000 homes were still without power on the second . day of the storm and many had no heat. Specific damage to Townships, Villages, and Hamlets in SC include, but are not limited to, the following: · Babylon: Natural gas service shut offto about 2,400 homes in most in danger of flooding, such as Babylon, Lindenhurst, Amityville and Copiague. Flooding forced evacuations in Babylon where water swept over Montauk Highway. A half mile of beach on Cedar and Gilgo Beaches was submerged, water had breached bulkheads and flooded homes, and picnic tables were underwater. At Gilgo Beach, thousands of tons of sand that had been backfilled during the past several weeks as part of an Army Corp dredging project, was gone. LILCO gas service was shut off to flood prone areas south of Montauk highway in Babylon and Lindenhurst, which would affect 4,000 homes. Street flooding in Amityville is identified in Figure 5-7. · Brookhaven: Worst damage along SC's north shore appeared to be in Port Jefferson. Officials estimated that at least one mile of beach was lost and the boardwalk was swept out to sea with $400,000 in damage. Merchants in Port Jefferson averaged that tens of thousands of dollars in damage would cripple holiday businesses along Main Street. The village was inundated with more then 6 feet of water, causing many cars to be submerged. Mastic Beach was underwater. In Brookhaven, large trees fell across Brookhaven roadways, including an aged maple measuring more then 30 inches in diameter which blocked traffic along Main Street in Setauket. Cedar Beach near Sound Beach absorbed its worst pounding from storm damage since at least WWlI. · East Hampton: People were found stranded on Lazy Point near Amagansett. In Sag Harbor, there was waterfront erosion along Bluff Point and the Redwood section. · Fire Island: The storm breached Fire Island in five places in Atlantique, Ocean Bay, Dunewood, and Cornell Estates. Eleven homes were destroyed and many were damaged. A dune was breached and the water was 150 feet away from the road. Fire Island lost about 16 homes. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.1-11 DRAFT- September 2007 SECTION 5.4.1: RISK ASSESSMENT - NOR'EASTER Western stretches of Fire Island beach and adjacent parts of Robert Moses were covered with lumber, shingles, household appliances, and possible dangerous propane tanks. A hull of a wooden ship~ possibly dating to the turn of the century, poke through the sand. Because of the many dangers on the Fire Island, it was closed to the public. · Huntington: Eaton Neck and Asharoken were cut off from the mainland by 5 feet of water. Wires were down and homes were flooded. On Eaton's Neck, there was no heat, electricity and access to mainland as a result of storm. Over 1,500 residents were cut off from the mainland and four homes were washed into the water. In Lloyd Neck, water inundated the main road and ripped up docks and beach steps. In Northport Harbor, the rising water covered the village dock and crept into the harborside park. In Centerport, Mill Dam Bridge was closed and flooding of Halesite and Huntington Bay. First time in 30 years that the causeways to Lloyd's Neck and Asharoken were both under water. Parts of Asharoken remained under water deep enough to prevent the NYS Army National Guard from getting to Eaton's Neck residents. - · Islip: Homes and surrounding properties in Saltaire were worth at least $350 K, which many were lost or damaged. Beach erosion and movement of water caused the shoreline to almost be instantly redrawn. One house was lost in Saltaire, all of the dunes and 18 feet of boardwalk were swept away. · Riverhead: In Riverhead, a kayaker paddled down Peconic Bay Blvd. The sea surged into Peconic Bay, pushing a wall of water into the Peconic River, flooding parts of downtown Riverhead. · Shelter Island: There was extreme flooding and a lot of damage. One house was lost to a fire and many houses had their roofs blown off. · Smithtown: Finger slips and docks stored at the town's harbor facility were ripped from their concrete moorings. Callahans Beach in Kings Park suffered some erosion. Nissequogue River was flooded near the Landing Avenue Bridge, and for the first time, Jericho Turnpike flooded near the Smithtown Bull statue. · Southampton: Worst damage along SC's south shore appeared to be in Westhampton, with 25 homes swept into the sea. According to a Governor Pataki news release, the Shinnecock Inlet has experienced increasing erosion (a problem that culminated as a result of a washout and breach that followed the December 1992 Nor'Easter). This event forced the commercial fishing fleet to temporarily abandon its home port, which generates an annual catch valued at more the $15 million (Long island Hurricane History, 2007). Additional town specific damage information is identified in a June 1994 Final Report-Environmental Study of the Barrier and Bay Island Communities in the Town of Babylon, produced by Cashin Associates, P.C. (Cashin, 1995). This report documents that the storm caused severe coastal flooding and erosion damage throughout various sections of the Town of Babylon. The Town of Babylon's Outer Beach communities experienced relatively minor flood damage; however, damage in other communities along coastal Long Island were much more severe, including Bayville and Asharoken on the north shore and Fire Island and Westhampton Beach on the south shore. The magnitude of storm damage within this area included the following: Fire Island Inlet: A dredging/beach nourishment project which entailed widening Gilgo Beach with dredge spoil (0.8 million cubic yards) was underway when the Nor'Easter hit. This storm washed away most of the sand that was placed along the Gilgo Beach during this project. Dune erosion also was severe at the West Gilgo Beach ocean shoreline. The loss of dune material at DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.1-12 DRAFT - September 2007 SECTION 5.4,1: RISK ASSESSMENT - NOR'EASTER this location resulted from toe erosion (when storm waves wash materials from the base of the dunes, causing the overlying dune sediments to slide down to the beach). · Complete dune washout occurred along most of the 3,000-foot long segment of shoreline extending westward from the Gilgo Beach community. Flooding occurred at a number of locations within the residential comlnunities of the Outer Beach (particularly at Gilgo Beach and Oak and Captree Islands). Flood waters penetrated the first floor of a number of houses at these locations. · The boardwalk that extended along the entire length of Oak Island was severely damaged with large sections of walkway obliterated (Cashin 1994). A September 1994 Governor's Coastal Erosion Task Force (Final Report Volume One - Emergency Response to Coastal Storms), indicates that this Nor'Easter event resulted in a significant amount of coastal erosion along a majority of SC's shorelines. The December Nor'Easter of 1992 and other less damaging 1993 winter storms (e.g., March 12 to 14, 1993 Nor'Easter), caused widespread physical problems, including extensive beach erosion, dune scarping, and overwash, bluff erosion, flooding, significant structural damage, and disruption of transportation, utilities and essential services. FEMA reported that direct federal disaster assistance through July 1993, which includes disaster funds for the December 1992 storm and the March 1993 storm, totaled $233.6 million. This storm proved highly destructive to transportation, utilities and essential services. Dune Road was severed by the breaches at Westhampton and broken by the washover west of Shinnecock Inlet. Ocean Parkway was in jeopardy of breaching. Babylon, Mastic Beach, and Shirley all reported problems with street flooding. In the Town of Smithtown, the sole access roads to the Short Beach and Long Beoch peninsulas were flooded. Residents of Eaton's Neck were isolated by flooding at Asharoken Avenue. After the storm, beaches, dune washovers, and developed areas that experienced flooding or wave damage were littered with pieces of building materials from broken decks, boardwalks, docks, and shorefront homes. Jones Beach and Robert Moses State Park reportedly had between 4~000 and 5,000 cubic yards of stockpiled debris after cleanup efforts. Other impacts from the storms include; · Serious flooding of streets and houses occurred in Mastic and Shirley Beaches in Town of Brookhaven. · Serious flooding resulted along the lower Browns River Road and access to the Bay Shore Marina in the Town of Islip. · Extensive flooding in the Village of Remsenburg in the Town of Southampton (Cuomo, 1994). Details regarding coastal erosion impacts from this storm are presented later in this section (Section 5.4 - Coastal Erosion).

It resulted in a FEMA Emergency Declaration (EM), including SC, identified as EM 3107. It was a massive storm complex, affecting at least 26 U.S. states and much of eastern Canada (Figure 5-11 ). According to the NCDC Technical report 93-01: "A Review Of The March 12-14, 1993 "Storm of the Century," this storm reportedly caused over $6 billion in damages along the eastern coast of the U.S and resulted in over 270 fatalities (23 fatalities in NYS) (Lott, 1993). According to NYSEMO, the 1993 blizzard resulted in total eligible damages of approximately $8.5 million across NYS. Damage on Fire Island was extensive. The New York Times reported that 12,000 homes sustained storm damages, including on Fire Island. The storms were so powerful, they scoured from 70 to 100 feet of beach away, along almost the entire length of the island. Dunes were reduced to 0 to 8 feet in most places from their previous 15 to 25 feet (Ocean Beach and Fire Island, 2002). According to a Patchogue Village HMP, hundreds of roof collapses occurred in the northeast due to the weight of heavy wet snow during this storm. Over 3 million customers were without electrical power in the region due to fallen trees and high winds, which damaged power utility infrastructure. At least 18 homes fell into the sea on Long Island due to the pounding surf. This storm was the 4th costliest storm in U.S. history (Patchogue Village, 2006). Specific monetary losses for SC are not documented. Figure 5-11. "Storm of the Century" - March 12-15, 1993 Note: METEOSAT Infrared Satellite Photo of the March 1993 "Storm of the Century" (March I3, 1993) Source: (NOAA, Date Unknown) October 19-20, 1996 (FEMA DR-1146): The October 19-20, 1996 Nor'Easter delivered a devastating blow that was felt in Long Island and New York City. According to Mayor Rudolph Giuliani, the storm, which dumped nearly 4.8 inches of rain on the city and surrounding areas, caused significant damage to more than 1,000 homes, some of which remain uninhabitable to this day. All five boroughs of New York City and the counties of Nassau and Suffolk were declared major federal disaster areas as a result of damage to homes and businesses from the October Nor'Easter. President Clinton issued a major disaster declaration on November 19 at the request of Governor George Pataki, identified as DR-1146 (FEMA, 1996). Public assistance funding was provided for infrastructure repairs, including: damage to roads, bridges and other county and local facilities. Preliminary damage assessments for the two counties totaled DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.1-16 DRAFT - September 2007 SECTION 5.4.1: RISK ASSESSMENT- NOR'EASTER more than $3.5 million. This was the 1st Nor'Easter to strike the region in years, causing widespread flooding and causing the first game of the World Series to be canceled. Governor Pataki announced additional flood aid for this Nor'Easter on May 14. 1997, for SC totaling $285,775. April 14-16, 2007 ("The Beast from the East") (FEMA DR-1692): The Spring Nor'Easter of 2007, affected mainly the northeastern parts of the U.S, from 14 to April 16, 2007 (Figure 5-12). The combined effects of high winds, heavy rainfall, and high tides led to significant coastal erosion, flooding, storm damages, power outages, and evacuations, and disrupted traffic and commerce. The storm caused several fatalities. It hit the NYS area before dawn with pounding wind and rain, causing tides to surge against coastal beaches and riverfront communities, forcing the cancellation of more than 500 flights at the three major airports, closing 20 roads in New Jersey and others in NYS, cutting off power to 18,500 customers in three states, and tearing off a roof at an-apartment complex on Long Island. In Patchogue, high winds ripped the roof off a building in the Fairfield Apartments, and eight families were moved to another building in the complex. On Fire Island, where winds up to 50 miles an hour came in from the ocean, more than 1,000 people voluntarily evacuated (McFadden, 2007)_. Some of the impacts of this Nor'Easter within Long Island included: flooding in low-hying areas such as Freeport, and along Dune Road in Southampton and Asharoken Avenue in Asharoken. Route 25 in East Marion -- the only road to the Orient Ferry -- was closed and impassible There were reports of fallen trees, downed power lines, flooding, and threats of erosion across the region. For one night, Sunrise Highway in Water Mill was closed both ways because of downed power lines and trees. More than 500 flights were canceled at the region's major airports, though Long Island MacArthur Airport in Islip reported only scattered delays on some flights (Freedman, 2007)._ On April 30, 2007, U.S. Senator Charles E. Schumer, SC Executive Steve Levy, and Babylon Town Supervisor Steve Bellone toured storm-hammered areas in Gilgo Beach in the Town of Babylon to assess the damage and discuss the recovery efforts from the destructive April 2007 Nor'Easter. This storm caused over $26 million in damage in SC, including significant erosion, flooding, and damage to homes, businesses, and infrastructure. Cupsogue Beach County Park in Westhampton was hit with over $5 million in damage while millions more in damage affected Smith Point County Park in Shirley. Major erosion and flooding also occurred at places like Captree State Park, Heckscher State Park, Caumsett State Park, Orient Beach, and Montauk Point. The storm led to the partial collapse of a road at Orient Point State Park. According to the Town of Babylon, homes and businesses south of Montauk Highway encountered significant damage. On the East End, towns like Southold heard from homeowners with flooded basements. Long Island was also plagued by flooding, especially in communities like Copiague, Amityville, Lindenhurst, Lake Ronkonkoma, and Babylon. Rain totals ranged from 1.5 inches to close to 4 inches. Across Long island, almost 18,500 LIPA customers experienced power outages (Schumer, 2007)_. As of May 3, 2007, FEMA announced that SC, along with other counties, was declared a disaster area eligible for Public Assistance, identified as DR-1692. Disaster assistance was approved for state and local government and certain non-profit organizations in 12 NYS counties, including SC (Figure 5-15). Disaster aid for SC has not been reported (FEMA, 2007). Details regarding coastal erosion impacts from this storm are presented later in this section (Section 5.4 - Coastal Erosion).

The NYS HMP conducts a similar ranking process for hazards that affect the State. The probability of occurrence, or likelihood of the event, is one parameter used for ranking hazards. Based on historical records and input from the Planning Committee, the probability of occurrence for Nor'Easters in SC is considered frequent [hazard event that occurs more frequently than once in 10 years (>10-~/yr), as presented in Table 5-4]. It is estimated that SC and all of its jurisdictions will continue to experience the direct and indirect impacts of Nor'Easters/extratropical storms annually that will induce direct impacts and may induce secondary hazards such as coastal erosion, coastal flooding~ utility failure, and transportation accidents. 6~A ~006 i-ta~aid ~iiigaii~h Plan 2 SUffolk CountYl N~w Y~rk 5A.}1:i9 DRAFT- September 2007 SECTION 5.4.t: RISK ASSESSMENT- NOR'EASTER VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. For Nor'Easter events, all of SC has been identified as the hazard area. Therefore, all assets in SC (population, structures, critical facilities and lifelines), as described in the County Profile section (Section 4), are vulnerable. The following text evaluates and estimates the potential impact of Nor'Easter events on SC including: Overview of vulnerability · Data and methodology used for the evaluation · Impact, including: (1) impact on life, safety and health of County residents, (2) general building stock, (3) critical facilities, ~nd (4) economy · Further data collections that will assist understanding of this hazard over time · Overall vulnerability conclusion Overview of Vulnerability As described earlier, Nor'Easters are one of two types of coastal storms that affect Long Island (the other being a hurricane). These two types of storms can cause a similar level of devastation (Cashin, 1994). The entire inventory of the County is at risk of being damaged or lost due to impacts of Nor'Easters. Certain areas, infrastructure, and types of building are at greater risk than others due to proximity to falling hazards and their type of construction. The specific impacts on population, existing structures, critical facilities and the economy are presented in the hurricane, flooding, coas;ral erosion and severe winter storm hazard profiles. Data and Methodology Nor'Easters can cause heavy snow, rain, gale force winds, and oversized waves (storm surge) that can cause beach erosion, coastal flooding, structural damage, power outages and unsafe human conditions. Step 4 in FEMA's How To 386-2 describes the factors to consider when assessing the vulnerability of buildings in coastal storms; these include: (1) storm surge flooding; (2) erosion or scour; and (3) strong winds. Potential losses associated with high wind events were calculated for SC using HAZUS-MH for two probabilistic wind/hurricane events, the 100-year and 500-year MRP events (see the Hurricane hazard profile). To assess SC's vulnerability to coastal flooding and coastal erosion, potential losses were calculated for SC using HAZUS-MH for 100- and a 500-year MRP flood events and the CEHA data provided by NYSDEC to determine what assets are exposed to coastal erosion (see the Coastal Erosion hazard profile). To estimate losses due to heavy snow, historic data and current modeling tools are not considered adequate to estimate specific losses that are a potential for this hazard. As an alternate approach, this plan considers percentage damages that could result from severe winter storm conditions (see the Severe Winter Storm hazard profile). Impact on Life, Health and SafeU, The entire County is identified as the hazard area vulnerable to Nor'Easters. According to the 2000 U.S. Census, SC had a population of 1,419,369 people. Vulnerable populations, including the elderly and low income populations, are considered most susceptible to the Nor'Easter hazard. Socially vulnerable populations are most susceptible, based on a number of factors including their physical and financial ability to react or respond during a hazard and the location and construction quality of their housing. Low DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.1-20 DRAFT- September 2007 SECTION 5.4.1: RISK ASSESSMENT- NOR'EASTER income residents may not have adequate housing able to withstand high winds, rain and snow associated with Nor'Easter events. The 2000 U.S. Census indicates that there are 5,374 mobile homes in SC. Impact on General Building Stock The entire general building stock inventory in the County is vulnerable to Nor'Easters. The data in HAZUS-MH estimates that there are 461,871 structures in SC, with a total building replacement value (structure and content) of greater than $210 billion. Approximately 99% of the buildings and 84% of the building stock structural value are associated with residential housing. Because of differences in building construction, residential structures are generally more susceptible to coastal storms than commercial and industrial structures. Please refer to Table 4-2 in Section 4 (County Profile) which presents building stock statistics by occupancy class for the County. HAZUS-MH was used to estimate potential losses to structures due to high wind events. Please refer to the Hurricane profile later in this section for a detailed look at potential estimated building values (structure and content) damaged by 100-year and 500-year MRP wind events (hurricane). In addition, a specific area that may be vulnerable to the Nor'Easter hazard is the floodplain, especially low-lying coastal zones. Infrastructure at risk due to coastal flooding is presented in the Flood hazard profile. · In the past, hundreds of homes have been destroyed and thousands damaged due to the wind, precipitation ahd/or flooding associated with Nor'Easter events. More specifically, Nor'Easters have also caused roofs to collapse due to the weight of heavy snow. Coastal communities are particularly vulnerable, especially structures on the protective barrier beaches. Impact on Critical Facilities All critical facilities are considered vulnerable to the Nor'Easter hazard. Section 4 of this Plan (County Profile) discusses the critical facilities in SC and the estimated replacement value for critical facilities and infrastructure. Estimated potential impact on these facilities is outlined in the hurricane, flood and severe winter storm hazard profiles. Because power interruption can occur, backup power is recommended for all critical facilities. Impact on Economy The 'pigh winds and heavy precipitation associated with Nor'Easter events often cause power outages, disruptions to transportation corridors and equipment, and loss of workplace access, all of which impact the local economy. Additionally, damage can also be inflicted by trees, branches, and other objects that fall onto power lines, buildings, roads, and vehicles. Sufficient information was not available to perform a detailed assessment of estimated losses to the economy. It is estimated that the impact to the economy, as a result of a Nor'Easter event, would be considered "high" in accordance with the risk ranking shown in Table 5-5. Additional Data and Next Steps In summary, Nor'Easters can cause heavy precipitation, gale-force winds, and oversized waves (storm surge) that can cause beach erosion, coastal flooding, structural damage, power outages and unsafe human conditions. This level of devastation is similar to that of a hurricane. Over time, the County will obtain additional data to support the analysis of this hazard. The County will continue to work together with local, state, and federal entities to learn more about the hazards associated with a Nor'Easter, and support further mitigation efforts as discussed in Section 6 to reduce the losses when future Nor'Easter events occur. Data that will support future analysis would include additional detail on past hazard events and DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.1-21 DRAFT- September 2007 SECTION 5.4.t: RISK ASSESSMENT- NOR'EASTER impacts, specific building information such as first floor elevation, type of construction, foundation type and details on protective features (e.g, hurricane straps). In addition, information on particular buildings or infrastructure age or year built would be helpful in future analysis of this hazard. As will be described later in the hurricane hazard profile, HAZUS-MH was customized to analyze the combined wind and flood hazards for SC. In time, HAZUS-MH will be released with modules that address wind and flooding as one model. As this version of HAZUS-MH is released, SC can run analyses for an overall picture of the associated wind and flood damages caused by hurricanes and use these results to also estimate damages caused by Nor'Easters. Additionally, refinement of floodplain maps and improvement of local inventory data will support refined analyses using HAZUS-MH over time. Overall Vulnerabili~, Assessment Historically, Nor'Easters have devastated the study area, causing impacts and losses' to the County's structures, facilities, utilities, and population. Existing and future mitigation efforts should continue to be developed and employed that will enable the study area to be prepared for these events when they occur. The overall hazard ranking determined by the Planning Committee for this hazard is high (see Tables 5-6 and 5-7). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.1-22 ORAFT-September 2007 SECTION 5.4.2: RISK ASSESSMENT - SEVERE WINTER STORM 5.4.2 SEVERE WINTER STORM This section provides a profile and vulnerability assessment for the severe winter storm hazard. HAZARD PROFILE This section provides profile information including: description, location and extent, previous occurrences and losses and the probability of future occurrences. Description Winter storms deposit precipitation (e.g., snow, sleet, freezing rain or ice) and can have a significant impact on transportation systems and public safety. "Nor'easters" are a common severe winter storm for the eastern portion of NYS and produce gale force winds and deposit over nine (9) inches of snow; given the frequ.ency of Nor'easters in the study area and their severe potential impact, Nor'easter storms are considered by the SC planning committee as a separate hazard and are further discussed in a separate section within this HMP. According to the NYS Plan, winter storms are frequent events for the State and occur from late October until mid-April. Snowstorms are complex phenomena whose impact can be affected by a great many factors, including a region's climatologically susceptibility to snowstorms, snowfall amounts, snowfall rates, wind speeds, temperatures, visibility, storm duration, topography, and time of occurrence during the day (e.g., weekday versus weekend), and time of season. The most severe categories of winter storms include the following: Heavy Snow: This includes significant accumulations of snow in a short period of time. Heavy snow generally means snow accumulating four or more inches in less than 12 hours. Snow squalls or brief intense snow showers accompanied by gusting winds can deposit significant amounts of snow (NOAA, 2001). Blizzard: Blizzards are characterized by low temperatures, wind gusts of 35 miles per hour (mph) or more and falling and/or blowing snow that reduces visibility to 0.25 miles or less for an extended period of time {three or more hours) (NWS, 2005). Sleet or Freezing Rain: Sleet is rain that freezes into pellets before reaching the ground. Freezing rain is rain that falls onto a surface with a temperature that is below the freezing point; the rain then freezes on the ground surface. Both types of precipitation, even in small accumulations, can cause significant hazards to a community (NOAA, 2001). Ice storm: During an ice storm, freezing rain produces significant and damaging accumulations of ice (0.25 inches or greater). When rain falls and freezes immediately on impact; communications and power can be disrupted for days; even small accumulations of ice may cause extreme hazards to motorists and pedestrians (NOAA, 2005). Location and Extent All of SC is susceptible to severe winter storms. Figure 5-16 indicates the mean annual snowfall for the U.S., including NYS. The mean annual snowfall for SC is 24.1 to 36.0 inches. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2-1 DRAFT- September 2007 SECTION 5.4.2: RISK ASSESSMENT - SEVERE WINTER STORM Figure 5-16. Annual Mean Snowfall within the Eastem United States and New York State Mid -Atlantic to New England Extreme cold Source: "Winter Storms The Deceptive Killers" Winter Storm Hazards in U.S. Annual Mean Snowfall - U.S. Department of Commerce, NOAA, NWS. December, 2001. (NOAA, 2006). Note: The red circle within NYS indicates the approximate location of SC. Annual mean snow fall within SC ranges between 24.1 to 36.0 inches. The magnitude or severity of a severe winter storm depends on several factors including a region's climatologically susceptibility to snowstorms, snowfall amounts, snowfall rates, wind speeds, temperatures, visibility, storm duration, topography, and time of occurrence during the day (e.g., weekday versus weekend), and time of season. The extent of a severe winter storm can be classified by meteorological measurements, such as those above, and by evaluating its societal impacts. The Northeast Snowfall Impact Scale (NESIS) categorizes snowstorms in this manner. Unlike the Fujita and Saffir-Simpson Scales that characterize tornados and hurricanes, respectively, there is no widely used scale to classify snowstorms. NESIS was developed by Paul Kocin of The Weather Channel and Louis Uccellini of the NWS to characterize and rank high- impact, Northeast snowstorms. The rating can range from a numerical value of 1 to 10 or greater. This numerical ranking is then used to categorize storms that have large areas of 10-inch or greater snowfall accumulations, using the following five NESIS categories: Notable (1), Significant (2), Major (3), Crippling (4), and Extreme (5) (Table 5-11 ). The index differs from other meteorological indices in that it uses population information in addition to meteorological measurements; therefore, NESIS gives an indication of a storm's societal impacts. This scale was developed because of the impact Northeast snowstorms can have on the rest of the country in terms of transportation and economic impact (Kocin & Uccellini, 2004). These storms are notable for their large areas of 4-inches (in.) (10- 1 Notable 1.0 - 2.49 cenimeter (cm)) accumulations and small areas of 10-in. (25-cm) snowfall. Includes storms that produce significant areas of greater than 10-in. (25-cm) snow accumulation, while some include small areas of 20-in. 2 Significant 2.5 - 3.99 (50-cm) snow accumulation. A few cases may even include relatively small areas of very heavy snowfall accumulations [greater than 30 in. (75 cm)]. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2-2 DRAFT- September 2007 SECTION 5.4.2: RISK ASSESSMENT - SEVERE WINTER STORM This category encompasses the typical major Northeast snowstorm, with large areas of lO-in, snow accumulation (generally between 50 3 Major 4.0-5.99 and 150 x 103 square miles ~oughly 1 to 3 times the size of NYS-- with significant areas of 20-in. (50-cm) accumulations. These storms consist of some of the most widespread, heavy snows and can be best described as crippling to the northeast, with the impact to transportation and the economy felt throughout the United States. 4 Crippling 6.0 - 9.99 These storms encompass huge areas of lO-in. (25-cm) snowfalls, and each case is marked by large areas of 20-in. (50-cm) and greater snowfall accumulations. The storms represent those with the most extreme snowfall distributions, blanketing large areas and populations with sn .owfalls 5 Extreme 10 + greater than 10, 20, and 30 in. (25, 50, and 75 cra). These are the only storms in which the lO-in. (25-cm) accumulations impact an area of over 200 x 103 square miles and affect more than 60 million people. Source: (Kocin & UccellinL 2003) NESIS scores are a function of the area affected by the snowstorm, the amount of snow, and the number of people living in the path of the storm. These numbers are calculated into a raw data number ranking from '~ 1' for an insignificant fall to over "10" for a massive snowstorm. Based on these raw numbers, the storm is placed into its decided category (Enloe, 2007). The largest NESIS values result from storms producing heavy snowfall over large areas that inclt~de major metropolitan centers (Enloe, 2007). As indicated in Table 5-12, 34 high impact snowstorms were ranked that affected the Northeast urban . corridor, with most of those storms creating an impact on SC, as indicated in further detail later in this hazard profile.

These events also cause lost productivity and work time, school cancellations, transportation delays, increased road maintenance, and higher demands on community services. Snow and ice-covered surfaces result in significant damage to trees, building and infrastructure inventory, such as power lines, bridges, and substations. The freeze/thaw cycle, salts, sand, and heavy use of plows and trucks that often accompanies winter storms result in the formation of potholes, damaged roads and bridges, and increased maintenance costs to a community. Snow Patterns on Long Island, NY The terrain over much of southern half of Long Island is a low lying gently sloping glacial outwash plain. The Harbor Hill moraine and the Ronkonkoma moraine (See Figure 5-17), both hilly deposits of debris left behind by retreating glaciers run nearly the length of Long Island across the north shore and over the center of the island, respectively. While the elevations in these hilly areas are not great, they range up to 300 to 400 feet above sea level at a number of locations. Generally speaking, these elevations are not high enough to result in significant amounts of precipitation, although it is likely that there is some minor enhancement from added lift near Long Island's morainal hills. Although the contribution of orographic lift to snowfall on Long Island is relatively minor, differences in elevation can sometimes produce noticeable effects during individual snowfalls. Small differences in temperature resulting from a combination of higher elevation and relative isolation from the warmer layer of marine air over the Long Island Sound can make a difference in snowfall amounts. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2~4 DRAFT- September 2007 SECTION 5.4.2: RISK ASSESSMENT - SEVERE WINTER STORM are 5-1 7. Harbor Hill and Ronkonkoma Terminal Moraine Ronkonkoma Terminal Moraine Source: (North Shore Wx, Date Unknown) Long Island can be divided into several different zones which average differing amounts of snow during the winter season. Thg snowiest pacts of the north shore may average as much as 50% more annual snowfall than the least snowy parts of the island. Limited data available suggest that average annual snowfall at the snowiest location on Long Island may approach 35-in. Anecdotal evidence suggests that parts of the West Hills area of Huntington town may one of the most snow-impacted places on Long lsland. The barrier islands offthe south shore of Long Island are almost certainly among the least snowiest parts of the island. (Northshore Wx, htlp://www.northshorewx.coln/Climate.asp). According to the NYS HMP, SC is the No. 22 County in NYS in temps of areas most threatened by snow and vulnerable to snow-related losses (NYS HMP, 2004). Previous Occurrences and Losses According to FEMA, NYS and SC has received one Disaster Declaration (DR) and two Emergency Declarations (EMs) for snow events between 1993 and 2003 (FEMA, 2006). EM 3107 was declared as a result of a state-wide blizzard in March 1993. According to NYSEMO, the 1993 blizzard resulted in total eligible damages of approximately $8.5 million. Specific losses for SC are not documented. DR 1083 was issued following a state-wide blizzard that took place in January 1996 known as the "Blizzard of '96," which resulted in $4.2 million in federal and state disaster funds being issued to 150 municipalities in seven counties of NYS (part of the ongoing recovery from the Blizzard of '96). EM 3184 was issued as a result ora snowstorm that occurred in February 2003. Information regarding disaster funding for SC was not made available in the sources reviewed.

D~A ~OOO I-{~-~;d ~iii~aiion Pi~ ~ Suffolk county, New York DRAFT- September 2007 SECTION 5.4.2: RISK ASSESSMENT - SEVERE WINTER STORM Notable winter storm events to impact the overall NYS area, including SC, are those that took place in March 1888 (Blizzard of '88), December 1947 (Big Snow), January 1978, February 1978 (Blizzard of 1978), March 1993~ January 1996 (Blizzard of '96), January 1997, January 2002, February 2003 (President's Day Storm), December 2003, January 2004, January 2005 and February 2006. It has been reported that the snowiest winter within SC was between 1995 and 1996; this winter created average snowfalls ofg0+ inches throughout the County. Details regarding winter storm events that have directly or indirectly impacted SC include the following: March 11-14, 1888 ("Blizzard of '88" or "Great White Hurricane"): The "Blizzard of '88," remains perhaps the most infamous and unpredictable of all Northeast snowstorms. This event paralyzed the east coast of the United States and Atlantic Canada from the Chesapeake Bay to Maine, and including the Maritime provinces of Eastern Canada (Figures 5-18 and 5-19). Telegraph infrastructure was disabled, isolating NY City, Boston, Philadelphia, Baltimore, and Washington, D.C. for days. Two hundred ships were grounded and at least one hundred seamen died. Fire stations were immobilized; property losses~ from fire alone were estimated at $25 million. It was identified that' over 3 feet of snow had accumulated within various locations of SC. Specific monetary losses were not documented in the materials available for review for SC; however, individual experiences are documented as follows by a 2000 Long Island Genealogy source: John Tooker of Islip, indicated that "Some small buildings were completely covered by drifts. The wind swept the ground bare in front of our kitchen door, and piled up the snow in a drift that reached so high it closed offthe view from two of our front room windows~" Margie Crossman of Huntington indicated that "Main Street in Huntington was filled up with ten or fifteen feet. It was so piled up that all the principal stores on the north side of Main Street moved all their goods to the second floor at the least sign of rain. When Main Street was dug out only narrow roads just wide enough for one way were dug. All the roads had to be dug out before they could be used. In some places they had to turn into the lots and make the road run through them for a ways. The trains are all blocked up. The one that started for New York from here last Monday has not got there yet and the one that left New York for here is a little more than half way here. The telegraph wires were all broken so that since one week ago yesterday only thirteen teen telegrams have been received in Huntington."

Source: (Long Island Library, 2006) December 26, 1947 ("Big Snow"): A post-Christmas storm caught New York residents by surprise, dropping two feet of snow in 24 hours (NSIDC, http://nsidc.org/snow/blizzard/storms.html). The storm would eventually become the worst blizzard in NY City and surrounding areas since 1888. Beginning the day after Christmas, 25.8 inches (nearly 100 million tons) of snow were dropped on city streets. Thousands of commuters were trapped in the city, stranded on trains and subways. Over 30,000 men worked for an entire week at a cost of $6 million to remove the snow. Seventy-seven people died in eight northeastern states (Thinkquest, Date Unknown). January 13-14, 1978 Ice Storm: After several minor snowfalls, this was the first major storm to hit Long Island during the winter of 1977-78. This was part of a storm that caused wide spread wintry DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2-9 DRAFT- September 2007 SECTION 5.4.2: RISK ASSESSMENT - SEVERE WINTER STORM weather along the east coast. Downed tree limbs and electrical lines caused major power outages from southern New England all the way down to central Georgia and Alabama. As ice accumulated, power outages began to occur widespread across large parts of the island, especially along the north shbre. The governor of NYS activated the National Guard to assist with the cleanup on Long Island and utility crews were brought in from hundreds of miles away to help with the repair of power lines (North Shore Wx,, Date Unknown). January 19-20 1978 (Near-Blizzard): The near-blizzard of January 19 - 20, 1978, was a surprise storm, creating a significant impact over a wide area of the northeast. Specific losses or impacts for SC are not documented; however, it was recorded that lslip received 17.0 inches of snow and Patchogue received 16.0 inches of snow (North Shore Wx,, Date Unknown). February 5-7, 1978 ("Blizzard of '78"): This event generated blizzard conditions across the Northeast. Long Island and New England were the hardest hit with near hurricane strength winds, thunder snow, and 36-hour storm duration (Weather2000, 2007). By' February 7, the storm had tracked north and taken on the cyclonic counter-clockwise flow characteristic of Nor'easters. At its peak, storm winds reached speeds of 86 mph with gusts of 111 mph. Along the New England Coast, more than 1,700 homes suffered major damage or were destroyed and 39,000 people took refuge in emergency shelters. Federal disaster assistance totaled $202 million. A 1978 news article written by Walter Kelly estimated that over $4 million in losses to SC resulted from the 1978 Blizzard, particularly in Brookhaven. Brookhaven received over 25 inches of snow during this event, which resulted in over $1 million in cleanup costs to residents. The cost to private businesses and individual in terms of storm damages, cleanup costs, snow removal, lost wages, and sales was roughly estimated at another $2.6 million. Medford and Farmingville were also hit hard by the storm. The event resulted in one death and the destruction of 16 vacation homes along Fire Island. At Davis Park, Fire lsland, four homes were washed down sand dues, and an additional 12 houses on Dune Road, Westhampton Beach remained perched precariously on stilts, surrounded by the ocean. Countywide, more than 80 beach front homes were toppled. The eight mile stretch of Fire Island suffered serious erosion. Many vehicles throughout Long lsland were abandoned in place during the storm, particularly along major highways, including Sunrise Highway (Figure 5°20). The worst hit areas in SC include Patchogue (Figure 5-21), Bellport, Brookhaven, Fire Island, Davis Park, Mastic Beach, Moriches and the Hampton Bays (Long Island Storm History, 2006) DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2-10 DRAFT- September 2007 SECTION 5.4,2: RISK ASSESSMENT - SEVERE WINTER STORM Figure 5-20.

It resulted in a FEMA EM, including SC, identified as EM 3107. It was a massive ~torm complex, affecting at least 26 states and much of eastern Canada (Figure 5-23). Overall, this storm reportedly caused a total of $6.6 billion in damages along the eastern coast of the United States and resulted in over 270 fatalities (23 fatalities in NYS) (Lott, 1993). According to NYSEMO, the 1993 blizzard resulted in total eligible damages of approximately $8.5 million through NYS. Damage on Fire Island was extensive. The NY Times reported that 12,000 homes sustained storm damages, including houses on Fire lsland. The storms were so powerful that they scoured from 70 to 100 feet of beach away, almost the entire length of the island. Dunes were reduced to 0 to 8 feet in height in most places (from a previous 15 to 25-foot height) (Ocean Beach and Fire Island, 2002). According to a Patchogue Village HMP, hundre~ls of roof collapses occurred in the northeast due to the weight of the heavy wet snow during this storm. Over 3 million customers were without electrical power ill Ibc region due to fallen trees and high winds. At least 18 homes fell into the sea on Long Island due to thc pounding surf. Through 2005, this storm was the 4th costliest storm in United States history I Patchouge Village, 2006). Mooctary losses were not documented in the materials available for review for SC. Achieving a NESIS rating of 12.52, the "Storm Of The Century" ranks as an Extreme snow event. With a total area impacting, at peak, from Maine to Florida, a final total 5 to 50 inches of snowfall, and hurricane force winds, this storm ground most of the Eastern seaboard to a halt for days (Figure 5-24) (Kocin & Uccellini, 2003).

This event was responsible for over 100 deaths and brought much of the east- northeastern United States to a complete halt. Schools, offices, and airports were closed for several days in some areas as roads were impassable. This event resulted in $4.2 million in federal and state disaster funds being issued to 150 municipalities in seven counties of NYS, including SC. Monetary losses were not documented in the materials available for review for SC; however, on Long Island it was the worst snowstorm since the Blizzard of 1978 in terms of snow, wind, and disruption of travel. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2-13 DRAFT - September 2007 SECTION 5.4.2: RISK ASSESSMENT - SEVERE WINTER STORM In SC, three men died from heart attacks while shoveling snow during this event. Eighteen people in the tri-state area suffered from "partial" carbon monoxide poisoning in their stranded cars. A State of Emergency was declared for southeastern NYS during the height o£the storm. Minor to moderate coastal flooding and beach erosion occurred along the south and north shores of Long Island. Along the south shore, a 50-year-old casino bar and restaurant in Davis Park (on Fire Island) was swept into the sea. In addition, three homes in the Fire Island Pines were destroyed, and Gilgo Beach lost 50 to 75 feet of sand. Just after high tide, up to 2 feet of water flooded downtown Ocean Beach where 150 families live. Extensive flooding was also reported in Atlantique, making driving down the main Fire Island (NWS, 1996). According to a NY Times News Article, the Blizzard of '96 brought Long Island to a standstill. The passenger airports were shut and all schools on Long Island were closed. Post offices were closed and mail was not delivered for a short period of time. Most bus routes were canceled and the Long Island Rail Road service suspended. Several days after the storm, the railroad had restored extremely limited service. In some low-lying coastal areas of SC, the water rose three to five feet above normal levels. Hard-hit areas included West Hampton Dunes, which lost 700 feet of roadways; Gilgo Beach, where 50 to 75 feet of sand washed away, and Fire Island, where a restaurant and several houses washed out to sea (Saslow, 1996).

The Sound does contribute to the amount of snowfall on Long Island, with the effect being most pronounced along thc north shore (North Shore Wx.). During the evening of January 7, 2002, a significant local enhancement of snowfall near the Long Island Sound occurred, created by a Long Island "Sound Effect". That evening, an upper level disturbance DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4,2-16 DRAFT - September 2007 SECTION 5.4,2: RISK ASSESSMENT - SEVERE WINTER STORM caused some very light snows over Long Island, with most accumulations being a half inch or less.

This event was the biggest on record for early December in NYS. Snow accumulations during this event on central Long Island reached over 18 inches. Two hundred customers of the Long Island Power Authority lost power during this event with most of them in the R iverhead area of SC (McFadden, 2003). January 27-28, 2004: This storm left from 10 to 15 inches of snow on the north shore of Long Island, including 13.5 inches measured in Smithtown (Figure 5-32). Widespread snowfall of a foot or more on top of approximately 4 inches of existing icy snowpack led to some of the greatest snow depths of the 2004 season (Northshore Wx, 2004). Figure 5-32.

February 1, 2004: An unusual amount of sea ice was found lining the edges of Long Island Sound in the Smithtown Bay area. Sea Ice is formed from ocean water that freezes. Because the ocean consists of saltwater, the freezing temperature of ocean water is lower than that for fresh water, which is 0 degrees Celsius (°C). Seawater freezes at about minus 1.8 °C.

January 22-23, 2005: According to the Upton NWS forecast office, snow amounts from this event ranged from 10.4 to 21 inches in SC (Figure 5-34). Baiting Hollow, Lake Ronkonkoma, Bridgehampton and Mount Sinai received the most. Maximum wind speeds ranged between 36 and 64 mph. Shinnecock Inlet and Orient Point received the most powerful wind speeds. During the storm, a coastal front formed and oscillated over Long lsland for a time. Temperatures steadily rose from the lower or middle teens at the beginning of the storm to near freezing for a time Saturday evening. Over the south shore of SC, temperatures rose to just above freezing for a few hours as heavy snow was falling, causing the snow to become wet and cling to trees and power lines. The weight of the snow combined with increasing winds caused numerous trees and power lines to be downed and resulted in scattered power outages. As the developing coastal low rapidly intensified, the colder air which had retreated only a few miles to the north was quickly drawn back over the island and temperatures plummeted back into the teens, turning the snowfall back into a fine powder (North Shore Wx, 2005). :igure 5-34.

According to the Upton NWS forecast office, snow amounts ranging from 9.0 to 20.0 inches in SC. Islip, Me,ford, Babylon (Figure 5-35) and Wading River reportedly received the most. Maximum wind speeds ranged between 36 and 64 mph (NWS, Date Unknown). This February 2006 snowstorm (see above) inundated the Northeast, closing regional airports, canceling hundreds of flights, and paralyzing normal traffic for city residents who took to the snow-caked streets in snowshoes and skis. The winter storm's high winds, icy snow, thunder and lightning hit much of the mid-Atlantic and New England region. A fairly large area was impacted, with snow accumulations of more than 20 inches in New Jersey, New York, and Connecticut. About 16 to 24 inches were expected throughout the NYS region, according to weather forecasters. The NWS described the weather conditions as "a major snowstorm" with winds up to 50 mph (The NY Times, 2006).

The NYS HMP includes a similar ranking process for hazards that affect the State. The probability of occurrence, or likelihood of the event, is one parameter used in this ranking process. Based on historical records and input from the Planning Committee, the probability of occurrence for severe winter storms in the County is considered high [hazard event that occurs more frequently than once in 10 years (>10-t/yr)]. It is estimated that SC and all of its jurisdictions will continue to experience severe winter storms annually that may induce secondary hazards such as utility failure, transportation accidents, and erosion along the north and south shorelines. VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. For severe winter storms, the entire County has been identified as the hazard area. Therefore, all assets in SC (population, structures, critical facilities and lifelines), as described in the County Profile section, are vulnerable to a severe winter storm. The following text evaluates and cst imates the potential impact of severe storms on SC including: · Overview of vulnerability Data and methodology used for the evaluation · hnpact, including: (1) impact on life, safety and health of SC residents, (2) general building stock, (3) critical facilities, and (4) economy · Further data collections that will assist understanding of this hazard over time · Overall vulnerability conclusion DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2-22 DRAFT- September 2007 SECTION 5.4.2: RISK ASSESSMENT - SEVERE WINTER STORM Overview of Vulnerabili~ Severe winter storms are of significant concern to SC because of the frequency and lnagnitude of thes'e events in the region, the direct and indirect costs associated with these events, delays caused by the storms, impacts on the people and facilities of the region related to snow and ice removal, health problems, cascade effects such as utility failure (power outages), traffic accidents, and stress on community resources. Data and Methodology FEMA, national weather databases and local resources were used to collect and analyze severe winter storm impacts on the County. Default HAZUS-MH data was used to support an evaluation of assets exposed to this hazard and the potential impacts associated with this hazard. Impact on Life, Health and SafeD' For severe winter storms, the entire County population is considered exposed to this hazard. Vulnerable populations, including the elderly and low income populations, are considered most susceptible to the severe winter storm hazard. Also, the high cost of fuel to heat residential homes can create a financial strain on populations with low or fixed incomes. In addition, low income residents may not have access to housing or their housing may be less able to withstand cold temperatures (for example, mobile homes and homes with poor insulation and heating supply). The elderly population has an increased risk of injuries and death due to falls and fi.om overexertion and/or hypothermia from attempts to clear snow. In addition, severe winter storm events can reduce the ability of these populations to access emergency services. Table 5-15 summarizes the population over the age of 65 and families with an income below $20,000 per year.

Pop. = Population Snow accumulation and frozen/slippery road surfaces also increase the frequency and impact of traffic accidents for the general population, resulting'in personal injuries. SC recognizes it has a large special.needs population and is committed to providing the best possible assistance to these citizens when an emergency is imminent. The SC Comprehensive Emergency Management Plan outlines the SC Joint Emergency Evacuation Program (JEEP). JEEP provides emergency evacuation assistance (shelter and transportation) to citizens that are particularly at risk during emergency situations. Impact on General Building Stock The entire inventory in SC is vulnerable to a severe winter storm. However, historic data and current modeling tools are not considered adequate to estimate specific losses that are a potential for this hazard. As an alternate approach, this plan considers percentage damages that could result from severe winter storm conditions. Table 5-16 identifies the exposed buildings and value in SC and losses that would result from 1, 5, and 10 percent damage to this inventory as a result of a severe winter storm· Given professional knowledge and information available, these are considered conservative estimates of potential losses for this hazard· Table 5-16.

The replacement building values shown are building structure only. For the severe storm hazard, damage will generally impact structures such as the roof and building frame (rather than building content). SM = One million. Manufactured (mobile) homes are particularly vulnerable to severe winter storms. The 2000 U.S. Census indicates that there are 5,374 mobile homes in Suffolk County. Table 5-17 estimates losses to this building stock estimate if5% and 10% damage accrues to these homes. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2-24 DRAFT- September 2007 SECTION 5.4~2: RISK ASSESSMENT - SEVERE WINTER STORM Table 5-17. Manufactured (Mobile) Homes Exposed in Suffolk County and Potential Severe Winter Storm Losses Source: US Census Bureau (2000): HAZUS-MH (2005) Notes: ( l ) US Census. (2) Total number of manufactured homes multiplied by the average value of a mobile home. According to HAZUS-MH, for Suffolk County, the average value ora manufactured home is estimated to be $37,000. $ M Million dollars. The replacement building values shown do not include building contents. Generally, for the severe xvinter storm hazard, the structural components of buildings are anticipated to be most impacted; therefore, contents were not evaluated for this hazard category. A specific area that is vulnerable to the severe winter storm hazard is the floodplain. Severe winter storms can cause flooding through blockage of streams or through snow melt. At risk residential infrastructure are presented in the presentation for the flood hazard. Generally, losses resulting from flooding associated with severe winter storms should be less than that associated with a 100-year flood. Please refer to the flood profile, in addition, coastal areas are at high risk during winter storm events that involve high winds. Please refer to the severe storm and/or Nor'easter profiles for losses resulting from wind. Impact on Critical Facilities HAZUS-MH estimates the replacement value for each police station is $1,652,000 and fire/EMS facility as $708,000. Additionally, HAZUS-MH estimates the replacement value for hospitals in the County is $8 - $16 Million each. These structures are largely'constructed of concrete; therefore, they should only suffer minimal structural damage from severe winter storm events. Because power interruption can occur, backup power is recommended for critical facilities and infrastructure; although this information is ' still being compiled, it appears that many such facilities have back-up power supplies. Infrastructure at risk for this hazard includes roadways that could be damaged due to the application of salt and intermittent freezing and warming conditions that can damage roads over time. Severe snowfall requires infrastructure to clear roadways, alert citizens to dangerous conditions, and following the winter requires resources for road maintenance and repair. Impacl ou Economy The cost of snow and ice removal and repair of roads from the fi'eeze/thaw process can drain local financial resources. The SC Department of Public Work. s clears County roads of snow and ice, while the State Highway Department is responsible for State highways and Town Highway Departments are responsible for local roads (SC Public Works, 2007). Severe x~intcr storms that impact SC generally impact Nassau County and New York City as well. The loss of power and closure of roads and/or mass transportation across the region due to the severe weather prevents the large Suffolk County commuter population from traveling to work or school. According to the U.S. Census, nearly 600,000 SC residents drive and more than 45,000 SC residents rely on public transporlalion to commute to work. Greater than 26 percent of SC work outside of the County, with a majority comnmting to Nassau County and NY City (Hevesi and Bleiwas, 2006). Additional Data and Next Steps Based on currently available data, modeling of future losses would only be possible for total losses and would haxc a large margin of uncertainty given the currently available data. However, the exposure assessmcm discussed above identifies vulnerable populations and infrastructure of particular concern for DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2-25 DRAFT - September 2007 SECTION 5,4,2: RISK ASSESSMENT - SEVERE WINTER STORM this hazard. Conservative estimates of potential losses based on "percent of damage" assumptions also are provided in the tables in this section as a guide for planning mitigation options. In addition, past events indicate that significant damages may occur in the future including: damage to structures~ impacts on human health, and costs in terms of service disruptions, accidents, and damage to infrastructure. Additional information regarding localized concerns, past impacts and dollar losses specific to the County can collected and analyzed to help estimate future losses to inventory. This methodology is based on FEMA's How to Series (FEMA 386-2), Understanding Your Risks, Identifying and Estimating Losses (FEMA, 2001 ) and FEMA's Using HAZUS-MH for Risk Assessment (FEMA 433) (FEMA, 2004). Overall VulnerabiliB' Assessment Severe winter storms are common in the study area, often causing significant impacts and losses to the County and roads, structures, facilities, utilities, and population. The overall hazard ranking determined for this Plan for the severe winter storm hazard is high, with a frequent, probability occurrence [hazard event that occurs more frequently than once in 10 years (>104/yr)]. Because the area is frequently exposed to this event, it is prepared to respond. Existing and future mitigation efforts should continue to be developed and employed that will enable the study area to be prepared for these events when they occur. The cascade effects of severe winter storms include utility losses and transportation accidents and flooding. Losses associated with the flood hazard are discussed earlier in this section; damages associated with high winds that can occur concurrently with snow storms are discussed in the Severe Storm Hazard profile. Particular areas of vulnerability include low-income and elderly populations, mobile homes, and infrastructure such as roadways and utilities that can be damaged by such storms and the low-lying areas that can be impacted by flooding related to rapid snow mblt. Coastal areas also have significant risk if snow storms are associated with strong winds and seas. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.2-26 DRAFT - September 2007 SECTION 5.4.3: RISK ASSESSMENT - SEVERE STORM 5.4.3 SEVERE STORM This section provides a profile and vulnerability assessment for tile severe storm hazard. HAZARI) PROFILE This section provides profile information including: description, location and extent, previous occurrences and losses and the probability of future occurrences. Description The severe storm hazard includes hail, wind, lightning, thunderstorms, and tornados. Other severe storms include hurricanes/tropical cyclones and Nor'easters, which are discussed further in this section (Section 5.4). Due to the increased susceptibility of these hazards upon SC, they were considered major hazards that should be discussed individually within'this HMP; therefore, this section will not include information regarding historical hurricanes/tropical cyclones and Nor'easters. A description of hazards categorized as Severe Storms are provided below. Hail: Showery precipitation in the form of irregular pellets or balls of ice more than 5 millimeters (mm) in diameter, falling from a cumulonimbus cloud (NWS, 2005). Lightning: An electrical discharge that results from the buildup of positive and negative charges within a thunderstorm (NWS, 2006). Thunderstorm: A combination of moisture, rapidly rising warm air and a force capable of lifting air such as a warm and cold from, a sea breeze, or a mountain. All thunderstorms contain lightning and can produce hail (NWS, 2005). A thunderstorm produces wind gusts less than 50 knots (25 meter/seconds) and hail, if any, of less than 3/4-inch diameter (20 mm) at the surface. Wind or hail damage may be used to infer the occurrence/existence of a severe thunderstorm. Tornado: A violent windstorm characterized by a twisting, funnel-shaped cloud. It is spawned by a thunderstorm (or sometimes as a result of a hurricane) and produced when cool air overrides a layer of warm air, forcing the warm air to rise rapidly. The damage from a tornado is a result of the high wind velocity and wind-blown debris. Tornado season is generally March through August, although tornados can occur at any time of year (FEMA, 2004). Windstorm: Wind is air moving from high to low pressure. It is a rough horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface. It occurs at all scales, from local breezes generated by heating of land surfaces and lasting tens of minutes to global winds resulting from solar heating of the Earth. The two major influences on atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet. Windstorm events are associated with cyclonic storms (e.g., hurricanes), thunderstorms, and tornados (FEMA, 1997). Location and Extent Severe storms may affect the entire mitigation study area. The extent (that is, magnitude or severity) of a severe storm is largely dependent upon sustained wind speed. Figures 5-40 and 5-41 show designated wind zones that impact the United States and NYS, respectively. SC is located in Wind Zone II with speeds up to 160 miles per hour (mph) and is also located in the Hurricane-Susceptibility Region which extends along the southern and eastern coastlines. The NYS HMP indicates that SC is the No. 1 County DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.3-1 DRAFT- September 2007 SECTION 5.4.3: RISK ASSESSMENT - SEVERE STORM in NYS most threatened by extreme wind and vulnerable to extreme wind losses. Hurricanes are discussed later in this section (Section 5.4). Figure 5-40. Wind Zones in the United States WIND ZONES IN THE UNITED STATES* Source: FEMA Fil~ure 541. Wind Zones in New York State Wind Zones Source: New York State Hazard Mitigation Plan, 2005. The magnitude or severity of a tornado was originally categorized using the Fujita Scale or Pearson Fujita Scale (introduced in 1971). Other scales have been developed to measure wind and tornado intensity including the Beaufort Wind Scales (B-Scales) and Britain's Tornado Storm and Research Organization DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.3-2 DRAFT - September 2007 SECTION 5.4.3: RISK ASSESSMENT - SEVERE STORM (TORRO) Scale (T-Scale); however generally they are not used to identify the severity or intensity of a tornado or wind event in the United States. The Fujita Scale categorizes tornadoes from FO (Gale) to F5 (Inconceivable) based on wind speed (Table 5-18) (NOAA, Date Unknown). It is used to rate the intensity of a tornado by examining the damage caused by the tornado after it has passed over a man- made structure. Table 5-18. Fu e Scale Light damage. Some damage to chimneys; FO < 73 branches broken off trees; shallow-rooted trees pushed over; sign boards damaged. Moderate damage, Peels surface off roofs; F1 73-112 mobile homes pushed off foundations or overturned; moving autos blown off roads. Considerable damage.

Strong frame houses leveled off foundations and swept away; automobile- F5 261-318 sized missiles fly through the air in excess of 100 meters (109 yards); trees debarked; incredible phenomena will occur. Source: (NOAA. Date Unknown) However, this scale recently become obsolete, due to many weaknesses in the system that have resulted is misuse and/or misunderstanding of the scale. It was replaced on February 1, 2007, by the Enhanced Fujita Scale, or EF Scale (Table 5-19). This new scale continues to rate the strength of tornadoes in the Uniied States based on the damage caused. The scale has the same basic design as the original Fujita Scale (six categories from 0 to 5 representing increasing degrees of damage). It was revised to reflect better examinations of tornado damage surveys, to align wind speeds more closely with associated storm damage. As with the Fujita Scale, though each damage level is associated with a wind speed, the Enhanced Fujita Scale is a damage scale and the wind speeds associated with the damage listed remain unverified and little more than educated guesses. The EF Scale improved on the old scale on many counts--it accounts for different degrees of damage that occur with different types of structures based on how they are designed, both man-made and natural. It also provides much better estimates for wind speeds and sets no upper limit on the wind speeds for the strongest level, EF5 (NOAA-SPC, 2007).

Source: (Wikipedia. 2007) When using the EF-Scale to determine the tornado's EF-rating, one begins with a set of 28 Damage Indicators (Table 5-20). Each one of these indicators has a description of the typical construction for that category of indicator. The next step is to find the Degree of Damage (DOD). The DOD in each category is given, along with the expected estimate of wind speed, a lower bound of wind speed and an upper bound of wind speed. Table 5-20.

Previous Occurrences and Losses Severe storms are frequent events for SC. Data provided by FEMA on Presidential Declared Disasters identifies that no Presidential or Emergency Declarations specifically associated with severe storm events, excluding hurricanes or nor'easters, were reported for the SC.

DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.3-7 DRAFT - September 2007 SECTION 5,4.3: RISK ASSESSMENT - SEVERE STORM July 23, 1995 (Tornado): A tornado touched down in South Farmingdale, NY (eastern Nassau County) and North Babylon, NY (western SC). The twister touched down in three separate locations: the first two touch-downs in South Fanningdale cut a path 1/4 mile in length and 300 to 400 feet in width, while the third touched-down in North Babylon ( 100 yards in length and 100 feet in width. The majority of damage was to trees, which fell on houses, cars, pools~ and fences. Many sheds were lifted and smashed to the ground and there were reports of some houses receiving roof damage. One house had a porch ripped away. No injuries were reported (NRCC, 1995). According to NOAA-NCDC, this FO tornado caused $500,000 in damages in N. Babylon, due to downed trees and power lines and damaged homes and cars. July 18, 1997 (Thunderstorm): According to NOAA-NCDC, two "waves" of severe thunderstorms moved southeast across the area on this date. The first line of thunderstorms moved across Nassau and Western Suffolk Counties during the early afternoon. The second line of thunderstorms moved over the area during the evening. For the day, these thunderstorms caused two deaths and 24 injuries. Both lines of severe thunderstorms produced high winds. In addition, the first line produced large hail. Selected wind gusts from Western SC that were documented with the passage of the first line include: 60 mph at both Babylon and Farmingdale Airport; and 58 mph at Bohemia. Significant structural damage (several roofs were blown off businesses) resulted in five injuries in Deer Park. A NWS Meteorologist investigated this damage and concluded that it was caused by a microburst. At least 3 roofs were blown off (the K- Lombardi Repair Shop and 2 businesses on Price Parkway). In addition to the 1 inch diameter hail observed at Babylon, 3/4-inch diameter hail occurred at Deer Park. Monetary losses were not provided. February 12, 1998 (Lightning): According to NOAA-NCDC, a lighting event resulted in $100,000 in structural damages to a house in Ridge (Brookhaven) and Southold. Lightning caused significant structural damage to a house at 59 Giant Oak Road in Ridge. According to the Ridge Fire Department, ' lightning struck the house. Two-by-fours in the roof exploded and struck and punctured the house next to the one that caught fire. The second floor of this two-story Cape Cod was totally destroyed. Lightning also struck a house on Bay Haven Road in Southold. It gouged a hole at the base of a tree and carved a furrow across the lawn. Lightning struck the sprinkler system, hit the septic tank, ran along the pip~s, blew the cap from the waste pipe into the basement stairs (cracking them), and struck the clothes dryer which ignited a basement fire. February 18, 1998 (Lightning): According to NOAA-NCDC, as a warm front between two Iow pressure systems moved north, it produced heavy showers and thunderstorms. Lightning struck a house at 1445 Bay Shore Road in Greenport and set it ablaze. The house was totally destroyed. Two other houses in the Greenport area were also struck: minimal damage occurred to one house and no apparent damage occurred to the other house. Lightning also struck a propane tank next to a house in East Hampton. It ignited a fire that totally destroyed this house. Monetary losses were not documented in the materials available for review. June 2, 1998 (Lightning): According to NOAA-NCDC, as thunderstorms moved east across SC, they produced frequent lightning. Lightning struck a barn in East Hampton (at the Oakdale Farms property on Three Mile Harbor Road) and sent electricity through four volunteer firemen. All four men required hospital treatment. Lightning also struck a brick chimney in a Setauket home, causing bricks to fall into the backyard as well as into the structure itself. Monetary losses were not documented in the materials available for review. September 7, 1998 (Thunderstorm): According to NOAA-NCDC, an intense line of severe thunderstorms oriented from north to south developed during Labor Day afternoon ahead of a strong approaching cold front. As the storms moved east at 40 to 50 mph, they produced high winds, large hail, and an isolated tornado. Wind gusts from 60 to 80 mph downed many trees and power lines throughout DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.3-8 DRAFT- September 2007 SECTION 5.4.3: RISK ASSESSMENT - SEVERE STORM the area. In SC, high winds overturned many boats in the Great South Bay, downed large trees in West Babylon and Rocky Point, and downed large tree limbs in Wading River. One person died when a thunderstorm wind gust capsized a 19-foot sail boat in Great South Bay near Copiague. A Centerport woman, 36, and her daughter, 3, were injured when a tree fell on them in the parking lot of the Ground Round Restaurant and CVS on Fort Salonga Road. The following peak wind gusts were reported: 72 mph in Babylon and 65 mph in Fire Island. Monetary losses were not documented in the materials available for review. August 8, 1999 (Tornado): According to NOAA-NCDC and City-Data.com, an F2 tornado caused $1 million in damages and I injury in Mattituck to New Suffolk. A cluster of severe thunderstorms formed north of an approaching strong warm front and moved east-southeast, just north of the front. A severe thunderstorm produced a tornado along the south shore of the North Fork of SC on Long Island. The tornado touched down and lifted several times along a 4 mile path as it moved east-southeast from just southeast of Mattituck Air Base, across Marratooka Pt., Kimogener Pt. (of New Suffolk), 'Cutchogue Harbor, Central Nassau Pt., then lifted as it crossed Hog Neck Bay. NSW data indicate that the tornado touched down first in southern sections of Mattituck. This was in the backyard area bounded to the west by Marratooka Road, to the north by Center Street, and to the south by Park Ave. Most damage at this location was to trees, where many tops were twisted off and several snapped off at 5 to 15 feet above the ground. This was estimated as F1 damage. The tornado "bounced" and continued east to the dirt road extension of Park Avenue, ~vhere it lifted the roof off a cottage. The roof of the building detached from the house and was carried about 115 feet to the northeast. The tornado continued east for about 1/2 mile, then touched down again at 10 Kimogenor Point. It ripped off the porch and part of the main roof of the house at this address. It apparently developed a few separate vortices at this location. One twisted a 100 year old metal windmill over high tension power lines and did some significant damage to large trees. Another vortex slammed into the front porch at 2 Kimogenor Point and ripped off the porch and a large · section of the roof of the house. The lone inhabitant said he saw a "wall of water" heading toward his house and instinctively dove into the stone fireplace to protect himself as the storm hit. Winds were estimated over 100 mph over this part of the tornado's path. The tornado continued east along Jackson Avenue. impacting many mature trees in the area. The most significant damage occurred in the vicinity of Jackson Avenue and Fifth Street, where winds were estimated from 110 to 120 mph, based on the to the devastation of many large trees. This was the area where F2 damage was observed. This was also the widest path width, estimated at 300 yards. The tornado continued east along Jackson Avenue, creating Fl damage then went over Cutchogue Harbor. Eyewitnesses from Nassau Point (Little Hog Neck) said they saw the lornado over the water just east of New Suffolk. They saw several suction vortices rotating aroand the main funnel. The tornado moved across Nassau Point, in the vicinity of Wunnaweta Pond, where it twisted and sheared off many trees that fell (rn and damaged houses. It bounced again and hit close to the ground near #6225 and #6325 Nassau Point Road. Many trees fell onto, and damaged, homes. These backyards were on top of a cliff overlooking Hogs Neck Bay. The tornado lifted before hitting these homes. This was the last indication of tornado-related damage. The latest cost estimates of damage from the Southold Supervisor's Office are in excess of $1 million dollars. One injury occurred as a person was struck by flying debris. Jul3' 5, 2006 (Lightning): According to NOAA-NCDC, this event resulted in a 34-year-old man being struck by lightning while erecting a fence at Frank P. Long Intermediate School. No additional information was provided. August 25, 2006 (Tornado): According to Mr. Jack Boris of WCBSTV.com, an FO Tornado with winds of 60 to 70 mph occurred in SC on this date. There were reports of damage to trees and cars and Con Edison reported 14,000 customers without power (Boris, 2006). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.3-9 DRAFT - September 2007 SECTION 5.4.3: RISK ASSESSMENT - SEVERE STORM NOAA-NCDC indicated that a severe thunderstorm produced a weak FO tornado as it moved across extreme southeast Nassau County and extreme southwest SC on this date. The tnrnado's path length was only about ~¼ mile long and it's maximum path width was around 150 yards. There was significant tree damage along it's path. Rotation was evident based on impacts to the tops of many trees. The most damage occurred in East Massapequa between Merrick Road and Route 27A, Old Sunrise Highway. It was concentrated around Clocks Boulevard. southeast across Melrose Avenue and County Line Road, then across Amityville's Old Fields and Homestead Avenues. The tornado lifted into the parent cloud before reaching South Ketcham Avenue. This severe thunderstorm produced damaging winds, large hail, and torrential rain along it's path. Large tree branches were downed in Wantagh. Quarter size hail was reported in Farmingdale. Flash flooding also occurred along it's path. Monetary losses were not documented in the materials available for review. October 28, 2006 (Windstorm): As identified by (Long Island Hurricane History, 2007) a windstorm impacted sections of Babylon, NY (Figure 5-42). lmpacts and monetary losses were not documented in the materials available for review. :i~ure 5-42. October 28, 2006 Windstorm in Babylon, NY Source: (Long Island Hurricane History, 2007) Probability of Future Events In Section 5.3, the identified hazards of concern for SC were ranked. The NYS Hazard Mitigation Plan conducts a similar ranking process for hazards that affect the State. The probability of occurrence, or likelihood of the event, is one parameter used for ranking hazards. Based on historical records and input from the Planning Committee, the probability of occurrence for severe storms in SC is considered frequent [hazard event that occurs more frequently than once in 10 years (>104/yr), as presented in Table 5-4]; however, impacts only related to severe storms, excluding those associated with hurricanes, tropical storms and flooding, and Nor'easters are expected to be minimal. It is estimated that SC and ali of its jurisdictions, will continue to experience severe storms annually that may induce secondary hazards such as utility failure and transportation accidents. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.3-10 DRAFT- September 2007 SECTION 5,4.3: RISK ASSESSMENT - SEVERE STORM VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. For severe storms, the entire County has been identified as the hazard area. Therefore, all assets in SC (population, structures, critical facilities and lifelines), as described in the County Profile section, are vulnerable to a severe storm. The following text evaluates and estimates the potential impact of severe storms on SC including: Overview of vulnerability · Data and methodology used for the evaluation · Impact, including: ( 1 ) impact on llfe, safety.and health of county residents, (2) general building stock, (3) critical facilities, and (4) economy · Further data collections that will ass!st understanding of this hazard over time · Overall vulnerability conclusion Overview of Vulnerability As defined for this HMP, severe storms include hail, lightning, thunderstorms, tornadoes and windstornSs. The high winds and air speeds associated with these storm events often result in power outages, disruptions to transportation corridors and equipment, loss of workplace access, significant property damage, injuries and loss of life, and the need to shelter and care for individuals impacted by the events. A large amount of damage can be inflicted by trees, branches, and other objects that fall onto power lines, buildings, roads, vehicles, and, in some cases, people. The risk assessment for severe storm evaluates available data for a range of storms included in this hazard category. The entire inventory of the County is at risk of being damaged or lost due to impacts of severe storms. Certain areas, infrastructure, and types of building are at greater risk than others due to proximity to falling hazards and their type of construction. Potential losses associated with high wind events were calculated for SC using HAZUS-MH for two probabilistic wind/hurricane events, the 100-year and 500-year MRP events. The impacts on population, existing structures, critical facilities and the economy are presented in the hurricane profile. Data and Methodology FEMA's How-To //-2 (FEMA //386-2) states there are no standard loss estimation models and tables available to estimate losses from tornado events. FEMA does not describe methods to estimate losses from lightning, hail, or thunderstorm events. As advised by FEMA for estimating losses for tornadoes, national weather databases and local resources were used to collect and analyze severe storm impacts on the County. As discussed above, HAZUS-MH was used to calculate potential losses associated with high wind events (see the hurricane hazard profile). Impact on Life, Health and SafeD' The entire County is identified as the hazard area vulnerable to severe storms. According to the 2000 U.S. Census, SC had a population of 1,419,369 people. This number excludes the incoming commuter population and the seasonal population that increases in the summer months, when these hazard events typically occur. Per the planning department, it is estimated that the eastern SC population (Towns of Riverhead, Southold, Shelter Island, Southampton, and East Hampton) more than doubles during the DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.3-11 DRAFT- September 2007 SECTION 5.4.3: RISK ASSESSMENT - SEVERE STORM summer. Daytime in-commuting and seasonal changes in population (the summer) affect the total population vulnerable to this hazard and the number of residents that may evacuate, be displaced or require temporary to long-term sheltering. SC's current evacuation plans take temporal changes in population into account --Planning Committee please ver~, this statement. Vulnerable populations, including the elderly and 10w income populations, are considered most susceptible to the severe storm hazard. Socially vulnerable populations are most susceptible, based on a number of factors including their physical and financial ability to react or respond during a hazard and the location and construction quality of their housing. Low income residents may not have adequate housing able to withstand high winds associated with tornadoes (i.e., mobile homes). According to FEMA, the safest place for people during a tornado is in a safe-room or storm shelter designed to specific performance criteria. The 2000 U.S. Census indicates that there are 5,374 mobile homes in SC. Based on past occurrences of severe storm events in SC, injuries and loss of life resulted from fallen trees, flying debris and electrocution from a lightning strike. SC recognizes it has a large special needs population and is committed to providing the best possible assistance to these citizens when an emergency is imminent. The SC Comprehensive Emergency Management Plan outlines the SC Joint Emergency Evacuation Program (JEEP). JEEP provides emergency evacuation assistance (shelter and transportation) to citizens that are particularly at risk during emergency situations. Impact on General Building Stock The entire inventory in the County is vulnerable to severe storms. The data in HAZUS-MH estimates that there are 461,871 structures in SC, with a total building replacement value (structure and content) of greater than $210 billion. Approximately 99% of the buildings and 84% of the building stock structural value are associated with residential housing. Because of differences in building construction, residential structures are generally more susceptible to wind damage than commercial and industrial structures. Please refer to Table 4-2 in Section 4 (County Profile) which presents building stock statistics by occupancy class for the County. Current modeling tools are not available to estimate specific losses for this hazard, with the exception of windstorms. Please refer to the hurricane profile for a detailed look at potential estimated building values (structure and content) damaged by 100-year and 500-year MRP wind events (hurricane). According to FEMA's How-To #2 (FEMA #386-2), the most important factor in assessing vulnerability to tornadoes is to examine how likely structures will fail when exposed to winds that exceed their design or to flying debris that may penetrate the structure. "Structural damages from tornadoes are a function of the building's relative location to the tornado vortex, which cannot be predicted or mapped. In general, building damages can range from cosmetic to complete structural failure, depending upon the wind speed and location of the building with respect to the tornado path. Only a qualified architect or structural engineer can do more than the most rudimentary analysis of a building's capacity to resist the effects of a tornado." Page 4-27 of the guidance continues to state there are no building structure and content "...standard loss estimation models and tables for tornadoes..." The guidance advises to estimate structure and content vulnerability and content losses based on past occurrences of tornadoes. Available historic loss information indicates damages ranging from $50,000 to $500 Million per FO to F2 tornado event. A similar approach using historic structure and content losses to estimate damages to general building stock due to hail, lightning and thunderstorm events was used. In the past, buildings struck by lightning in SC have experienced minimal structural impact to total destruction (due to fire). For thunderstorms, DMA 2000 Hazard Mitigation Plan - Sulfolk County, New York 5.4.3-12 DRAFT - September 2007 SECTION 5.4.3: RISK ASSESSMENT - SEVERE STORM the only documented historic loss was three roofs blown off homes caused by a microburst. Monetary losses documenting structural damage as a result of hail, lightning and thunderstorm events was not found in available resources. A specific area that may be vulnerable to the severe storm hazard is the flood plain, including Iow-lying coastal zones. Thunderstorms are often accompanied by heavy rain causing flooding. Generally, losses resulting from flooding associated with thunderstorms should be less than that associated with a 100-year or 500-year flood. Infrastructure at risk due to flooding is presented in the flood hazard profile. Impact on Critical Facilities All critical facilities are considered vulnerable to the severe storm hazard. HAZUS-MH estimates the replacement value for critical facilities and infrastructure in SC (see Section 4 - County Profile). Because power interruption can occur, backup power is recommended. Severe storm events may require short-term sheltering of residents. FEMA recommends that communities assess the number, location, capacity and strength of shelters to ensure they can adequately house displaced residents and withstand design wind spend, especially for tornado events). Currently, SC has 127 designated shelters. The default replacement value for these shelters is $590,000 each with masonry construction. Table 4-11 lists the designated shelters in SC. Impact on Economy The high winds associated with severe storm events often cause power outages, disruptions to transportation corridors and equipment, and loss of workplace access, all of which impact the local economy. Additionally, damage can also be inflicted by trees, branches, and other objects that fall ont6 power lines, buildings, roads, and vehicles. Sufficient information was not available to perform a detailed assessment of estimated losses to the economy. It is estimated that the impact to the economy, as a result of severe storm event, would be considered '~low" in accordance with the risk ranking shown in Table 5- 5. Additional Data and Next Steps As defined for this plan, the severe storm event cannot currently be modeled in HAZUS-MH (tornado, thunderstorm, etc.). However, additional detailed loss data from past and future events will assist in assessing potential future losses. Based on these values and a sufficient number of data points, future losses could be modeled in some fashing. Alternately, percent of damage estimates could be made and multiplied by the inventory value to estimate potential losses. This methodology is based on FEMA's How To Series (FEMA 386-2), Understanding Your Risks, Identifying and Estimating'Losses (FEMA 2001) and FEMA's Using HAZUS-MH for Risk Assessment (FEMA 433) (FEMA 2004). SC will continue to compile data and track modeling tools to identify means to refine current loss estimates in the future. In addition, it will continue mitigation planning to be prepared for such events and minimize their impact on humans and structures in the future. Overall Vulnerability. Assessment Severe storms are common in the study area, often causing impacts and losses to the County's structures, facilities, utilities, and population. Existing and future mitigation efforts should continue to be developed and employed that will enable the study area to be prepared for these events when they occur. The overall hazard ranking determined by the Planning Cotmnittee for this hazard is high (see Tables 5-6 and 5-7). D~ ~000 ~id Miti~'~tion Plan 2 suffolk c0untyl New Yore DRAFT- September 2007 SECTION 5,4.4: RISK ASSESSMENT - HURRICANE 5.4.4 HURRICANE This section provides a profile and vulnerability assessment for the hurricane hazard. HAZARD PROFILE This section provides profile information, including: hazard description, hazard location and extent, previous occurrences and losses, and the probability of future occurrences. Description Coastal storms that affect Long Island fall into two general categories: hurricanes (tropical cyclones) and extratropical storms (midatlantic cyclones locally known as northeasters or nor'easters). Although these two types of storms can cause a similar level of devastation to developed coastlines, they are vastly- different with respect to origin and progression (Cashin Associates,' 1994). Therefore, these two types of coastal storms are divided into two separate hazards within this HMP. The hurricane hazard is the most intense type of tropical cyclone resulting in significant damages and loss of life. A description of Tropical Cyclone hazards is provided below. Tropical Cyclone: "Tropical cyclone" is a generic term for a cyclonic, low-pressure system over tropical or sub-tropical waters. A tropical cyclone is a warm storm system fueled by thunderstorms near its center. It feeds on the heat released when moist air rises and the water vapor in it condenses. The adjective "tropical" refers to both the geographic origin of these systems, which form almost exclusively in tropical regions of the globe, and their formation in Maritime Tropical air masses. The noun "cyclone" refers to such storms' cyclonic nature, with counterclockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Various terms are applied to tropical cyclones, depending on their location and strength (or speed), including: tropical depression, tropical storm, hurricane, typhoon, and cyclonic storm. Typhoon and cyclonic storms are not a concern for SC, therefore, further discussion of these terms are not presented in the HMP. While tropical cyclones begin as a tropical depression, meaning the storm has sustained winds below 38 mph, they may develop into a tropical storm (with sustained winds of 39 to 73 mph) or a hurricane (with winds of 74 mph and higher). Tropical cyclones contain a warm core of low barometric pressure and can produce heavy rainfall, powerful winds and storm surge. Tropical Depression: A tropical depression is an organized system of clouds and thunderstorms with a defined surface circulation and maximum sustained winds of less than 38 mph. A tropical depression has no eye and does not typically have the organization or the spiral shape of more powerful storms. Tropical Storm: A tropical storm is an organized system of strong thunderstorms with a defined surface circulation and maximum sustained winds between 39 and 73 mph. A tropical storm includes a distinctive cyclonic shape starts to develop, although an eye is not usually present. Hurricane: Hurricanes are caused by the atmospheric instability created by the collision of warm air with cooler air. They form in the warm waters of tropical and sub-tropical oceans, seas, or Gulf of Mexico. Most hurricanes evolve from tropical disturbances. A tropical disturbance is a discrete system of organized convection (showers or thunderstorms), that originate in the tropics or subtropics, does not migrate along a frontal boundary, and maintains its identity for 24 hours or more. Hurricanes are DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5,4.4-1 DRAFT- September 2007 SECTION 5.4.4: RISK ASSESSMENT - HURRICANE accompanied by torrential rains and one major cause of hurricane damage is storm surge. Hurricanes are intense, with wind speeds reaching a constant speed of 74 mph or more (FEMA, 2004). This category of tropical cyclone is characterized by thunderstorms and a defined surface wind circulation. Hurricanes begin when areas of loxv aUnospheric pressure move offthe western coast of Africa and into the Atlantic, where they grow and intensify in the moisture-laden air above the warm tropical ocean. Air moves toward these atmospheric lows from all directions and curves to the right under the influence of the Coriolis effect, thereby initiating rotation in the converging windfields. When these hot, moist air masses meet~ they rise up into the atmosphere above the low pressure area, potentially establishing a self-reinforcing feedback system that produces weather systems known to meteorologists as tropical disturbances, tropical depressions, tropical storms, and hurricanes (Frankenberg, 1999). Ahnost all tropical storms and hurricanes in the Atlantic basin (which includes the Gulf of Mexico and Caribbean Sea) form between June 1 and November 30, known as hurricane season (NWS, 2000). August and September are the peak months for Hurricane development. The threats caused by an approaching hurricane can be divided into three main categories: storm surge, wind damage, and rainfall/flooding: · Storm Surge - the storm surge is water that is pushed toward the shore as a result of rising sea levels due to the low pressure, high winds, and high waves associated with a storm as it makes landfall. This advancing surge combines with the normal tides to create a hurricane storm tide, which can increase the mean water level 15 feet or more. In addition, wind waves are superimposed on the storm tide. This rise in water level can cause severe flooding in coastal areas, particularly when the storm tide coincides with the normal high tides (NHC, Unknown). A storm surge creates a dome of water 40 to 60 miles long that moves onto the shoreline near the landfall point of the eye of the hurricane. A cubic yard of sea water weighs approximately 1,700 pounds. As this water slams into shoreline structures, even well-built structures quickly get demolished. As the waters move inland, debris floats along with the storm surge causing further damage. It is estimated that the storm surge is responsible for nearly 90% of all hurricane-related deaths and injuries. · Wind Damage - the force of wind associated with a hurricane causes wind damage. This wind damage can decimate the tree population, down power lines and utility poles, knock over signs, and may be significant enough to destroy some homes and buildings. Flying debris can also cause damage and in cases where people are caught outdoors, injuries and death. When hurricanes first make landfall, it is common for tornadoes to form; these tornadoes can cause severe localized wind damage. In most cases, however, wind is a secondary cause of damage. · Rainfall / Flooding the torrential rains that normally accompany a hurricane can cause serious flooding. While the storm surge and wind damage impacts are concentrated near the eye of the hurricane, rain and associated flooding may extend for hundreds of miles and may last for several days, affecting areas well after the hurricane itself has diminished (Mandia, Date Unknown). Location and Extent Because SC is primarily surrounded by coastal waters, hurricanes and other tropical cyclones can affect the entire mitigation study area, particularly impacting communities along the north and south shores of the County. Figures 5-43 and 5-44 show designated wind zones that impact the U.S. and NYS, respectively. SC is located in Wind Zone II with speeds that can reach up to 160 mph and identified in the Hurricane Susceptibility Region which extends along the eastern and southern coastline of the U.S. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-2 DRAFT- September 2007 SECTION 5,4,4: RISK ASSESSMENT - HURRICANE Multiple sources document that SC has been impacted by many hurricanes, tropical storms, and tropical depressions. The County has felt direct and indirect landward effects, including high winds, heavy rains, and major flooding associated with several hurricanes and tropical storms in recent history.

Historical Hurricane Tracks ( 1851-2002) Source: Tropical Prediction Center~qHC, 2003 The extent (that is, magnitude or severity) of a hurricane is categorized by the Saffir-Simpson Hurricane Scale. This scale categorizes or rates hurricanes from I (Minimal) to 5 (Catastrophic) based on their intensity. This scale is used to estimate the potential property damage and flooding expected in association with a hurricane landfall. Wind speed is the determining factor in the scale, as storm surge values are highly dependent on the slope of the continental shelf and the shape of the coastline, in the landfall region. Table 5-22 presents this scale, which is used to estimate the potential property damage and flooding expected when a hurricane makes land fall (NWS, 2006). Table 5-22.

Notes: mph=Miles per hour; >=Greater than; NA~aot applicable or not available In evaluating the potential for hazard events of a given magnitude, a mean return period (MRP) is often used. The MRP provides an estimate of the magnitude of an event that may occur within any given year based on past recorded events. In HAZUS-MH, a wind study was conducted for the County as a whole and for each participating jurisdiction for 100- and 500- year MRP events. This was necessary because no single storm can cause damage throughout a large study region such as SC. For example, a 100-year MRP event run for the County as a whole, may only cross the eastern side of SC and have little impact on a western SC (i.e., Town of Babylon). Therefore, each participating jurisdiction was set up as a separate study region in HAZUS-MH and a probabilistic 100- and 500-year MRP event was modeled for each jurisdiction. This methodology provided a more realistic probabilistic analysis and more accurate return period results for each participating Mean Return Period is the average pedod of time, in years, between occurrences of a particular hazard event (equal to the inverse of the annual frequency of exceedance). For example, a flood that has a l-percent chance of being equaled or exceeded ip any given year. This flood event is also referred to as the base tlood and has a MRP of 100. The term "100-year flood" can be misleading; it is not the flood that will occur once every 100 years. Rather, it is the flood elevation that has a 1- percent chance of being equaled or exceeded each year. Therefore, the lO0-year flood could occur more than once in a relatively short period of time. jurisdiction. Loss estimates and peak wind speeds are reported for each participating jurisdiction's model run and should not be added together to obtain a total for the County. A separate probabilistic 100- and 500-year MRP event was also modeled for the County as a whole, and these loss estimates and wind speeds should be used to assess County total estimates. Figures 5-46 through 5-68 show the estimated maximum 3-second gust wind speeds that can be anticipated in the study area associated with the 100- and 500-year MRP hurricane event model run for each participating jurisdiction. The estimated hurricane track for the 100- and 500-year event is also shown. The associated impacts and losses from these 100-year and 500-year MRP hurricane event model runs are reported in the Vulnerability Assessment later in this section.

The 1993 inundation maps were based on surge height projections calculated by the National Weather Service's "Sea - Lake Overland Surge from Hurricanes SLOSH Model." The surge heights were calculated for a number of category 1-4 hurricanes. This data was developed to delineate hazard zones and assess risk from hurricane-related storm surges and to support hurricane evacuation planning (NYSEMO, 2007). The bands of color in Figure 5-69 indicate areas at risk from progressively stronger categories of storms. According to computer projections based on SLOSH, large areas of coastal Long Island could be inundated by a storm surge from a major hurricane striking the island at high tide. The southem shore of SC is most at risk of inundation during a coastal storm, particularly in Babylon, Islip, Patchogue and Fire Island. Fire Island and its summer communities would be overrun by waves in the event of a major hurricane and direct land fall. The surging waters would cut off the eastern end of the South Fork at Napeague, making an island out of Montauk, and would swamp much of the North Fork. Ocean surf would cause major erosion (Rather, 2005). According to research by Scott Mandia, Professor of Physical Sciences at SUNY Suffolk, the following observations were made regarding the anticipated affects of a storm surge on Long Island. Category I hurricanes inundate just about all of the immediate south shore of the Island, including the north side of Great South Bay locations and both sides of the north and south forks. Montauk Highway (Rt. 27A) is completely covered by flood waters during a Category 3 hurricane. Therefore, this road would be considered impassable during the storm. The highest storm surges (Category 4) would occur in the following regions: Amityville Harbor - 29 feet Atlantic Beach & Long Beach areas - 24 to 28 feet South Oyster Bay, Middle Bay, & East Bay areas - 24 to 28 feet Montauk Point is completely cut off from rest of south fork during a category I storm. Much of the north and south forks are entirely under water during a category 3 hurricane. A category 4 hurricane inundates the entire towns of: Amityville, Lindenhurst, Babylon, West Islip, East Islip, Bayshore, Gilgo Beach, Cedar Beach, Great South Beach, Fair Harbor, Cherry Grove, Cupsogue, Westhampton Beach, Watermill Beach, Wainscott Beach, Plum Island, Gardiner's Island, Orient, Shelter Island (except for a few high points), Greenport, North Haven, Amagansett Beach, Napeague Beach, Montauk, Woodmere, Valley Stream, Linbrook, Long Beach, Atlantic Beach, Freeport, Merrick, Wantagh, Lido Beach, Jones Beach, and Tobay Beach (Mandia, Date Unknown).

The Historical Hurricane Information Tool (HHIT) served as a primary source to identify impacts to the SC area. The HHIT is based on ESRI's ArcView GIS, and was prepared by Brian Bossak and James Eisner of the Hurricane Climate Institute of Florida State University, to collate evidence of past hurricanes for the period 1800 to 1850. This period represents the years prior to NOAA's best-track dataset. HHIT brings together various historical archives into a single electronic reference source and adds value to historic archives by mapping available data. The HHIT includes a series of maps containing tropical cyclone information transcribed from historical source documents. The primary source is David DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-34 DRAFT- September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE Ludlum's 1963 AMS Monograph.

This Category 3 Hurricane was also one of the largest hurricanes to significantly impact the east coast, including the SC area. Although all of SC was directly impacted, the worst hit areas throughout SC included Westhampton, Southampton, Easthampton, Saltaire, Point' O Woods, Ocean Beach, Center Moriches, Sag Harbor, Fire Island, Smithtown, East Quogue, Bayshore, Merrick, Port Jefferson, Northport, Oak Beach (Babylon), Patchogue, Cormack, Stony Brook, St James, Hecksher Park. This hurricane made landfall near Bellport, NY (also, Westhampton and Southampton). The storm produced winds that reached 200 mph, generated 5-meter-high breakers, overwashed 1/3 to 1/2 of the island, and created about 12 new inlets (including the Shinnecock Inlet). Tom Morris and Bill Bleyer of Newsday indicated that it was one of the worst storm in recorded history for Long Island, in terms of fatalities (50+ people) and property damage (hundreds of homes were completely destroyed or suffered extensive damage); estimated damages of $6.2 million were incurred (in 1938 U.S. Dollars) for Long Island and nearly $ 6.0 billion in damages to the entire northeast. The Hurricane Research Division of the Atlantic Oceanographic and Meteorological Laboratory estimated that if an identical hurricane struck today it would cause nearly $23.5 billion in damage. Sources indicate that this hurricane resulted in a significant amount of damage throughout SC including, but not limited to, the following: One of the greatest impacts of the hurricane was creation of Shinnecock Inlet and widening of Moriches Inlet, which to this day, are changing the landscape of the south shore due to their influence on natural littoral sand transport. Ten additional inlets were created within Long Island, DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-37 DRAFT- September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE NY as a result of the storm.

The photographs were probably taken by the U.S. Army Air Corps~ Mitchel Field~ Long Island. · The hurricane resulted in 50 deaths on Long Island, with over 29 of those deaths in Westhampton. There were 21 other deaths within the eastern end of Long Island; however, actual location of these deaths was not documented. · Westhampton, was the worst hit of all the Long Island communities (a month after the storm, 4 persons were still missing, 29 deaths had occurred, and with 29 dead and 4 missing a month later, at least 150 houses were destroyed with a property loss of $2 million). A mile inland, the storm surge caused over 6 feet of water to flood Main Street. · Southampton suffered heavily along the shore front. From the bathing house to the municipal beach, only two cottages remained standing after the sea swept Dune Road. Among the shattered ruins was St. Andrew's Church of the Dunes. · The storm toppled the landmark steeple of the tallest building in Sag Harbor (the Whalers Church). The steeple still has not been rebuilt. · At Montauk, the hurricane rendered'150 fisherman homeless, destroyed or badly damaged more than 80 good-sized fishing craft, ruined scores of dragnets and fish traps (valued in some cases at $10,000 each), and nearly wiped out the sole year-round fishing industry at Montauk. About 100 houses were seriously damaged, six ending in the pond near the center of town; all power and lights were lost; the storm tore up miles of track along the Long Island Railroad - near Montauk Point. Even the roadbed was obliterated and the community was virtually isolated from the time the hurricane struck until two days later. Twenty-nine vessels used for various purposes, some worth as much as $25,000, had been blown ashore and lay from 100 to 300 feet up the beach, costing a fortune to repair (Allen, 1976). The oyster and clam industry also was wiped out as tons of sand smothered the entire harvest. · In East Hampton, the Atlantic Ocean split the town in two at Napeague during the storm. It also washed up sand so that the Cedar Point Lighthouse, which had been on an island, was connected to mainland. · At Bridgehampton, farmers were heavy losers; nearly 50 barns went down from Water Mill to Wainscott and north to the line of the Scuttle Hole Road. Potato farmers near the ocean found many acres washed out, washed away, or buried deep beneath sand fi.om the beach. On other fields that had been flooded with sea water, the potatoes rotted soon after being dug. Farmers lost garages, chicken houses, and outbuildings, as well as barns; more than 80 places suffered major losses. · Lieutenant Theodore Harris of the Coast Guard flew the length of Long .Island for eight hours trying to spot bodies and their locations. He saw 300 crushed and scattered houses at Ocean Beach, 100 demolished houses at Fair Harbor, and another 100 at Saltaire. There were about 40 houses largely inundated at Little Cap Tree Island. Approaching Westhampton, he stated that the land had the appearance of a child's room on New Year's Day, with all his toy houses and automobiles broken and warped. At least 100 automobiles were washed inland. · An estimated 3,500 trees were lost in the Bridgehampton-Sagaponack-Hayground area alone. Trees were down everywhere but there was a particularly heart-breaking story in East Hampton. The elms and locusts that formed an arch a half-mile long over Main Street had been planted before the American Revolution; they can still be seen in the canvases of many important painters. The trees were among the town's most cherished historical landmarks, but when the storm was over, 42 percent of the Main Street elms were gone. Sixty-eight trees fell in the middle of the road, torn to pieces. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-39 DRAFT - September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE Salt spray from wind-blown sea water and mixed rain water had the effect of browning the trees that did survive. Weeks later, these trees were dead. One can still find many downed trees throughout eastern Long Island's forest that are a direct result of this hurricane. In 1938, Long lsland salt marshes were inundated with tons of over wash (sand brought over the dune into marshland areas) that prevented the marsh grasses from growing back. This effectively decreased the area of the salt marsh for years (Mandia, 2006). In the June 1994 Final Report-Environmental Study of the Barrier and Bay Island Communities in the Town of Babylon, produced by Cashin Associates, P.C. (Cashin), the study notes that damage from the 1938 storm was intense on an Island-wide scale. Flood waters inundated approximately 35,000 acres between Fire Island Inlet and Montauk Point. The Oak Beach community of Babylon experienced major devastation. Houses were lifted off their foundations and carried inland for distances df 200 feet or more. It was estimated that over 50 house were either destroyed in-place, washed away, or moved from their foundations. The boardwalks of Oak Beach were completely washed away and large slabs of concrete were undermined and tossed about. Due to the tremendous volume of surge water that rushed through the underpass of Gilgo Beach, the Gilgo Inn was washed from its foundation and carried to the eastern end of the boat basin, a distance of about 700 feet. The marginal road of Oak Beach was reportedly under 8 feet of water. Only one fatality occurred in Oak Beach and few bodily injuries were sustained. On Fire Island, 1,000 homes were damaged or destroyed. Structural damage was ex/en more severe along the stretch of barrier in Westhampton Beach with only about 15% of the original 1;70 summer homes remained standing, of which only 7% were deemed to be salvageable (Cashin Assocaites, 1994).

It moved west-northwest through the 12th, then turned northward on a tract that brought the center near Cape Hatteras, North Carolina on the 14th. The cyclone accelerated north-northeastward, moving across eastern New England and into Canada by September 15th. The storm became extratropical over Canada and merged with a larger extratropical low on the 16th south of Greenland. This hurricane was of Category 3 intensity at landfall at Cape Hatteras, Long Island, and Point Judith, Rhode Island, and Category 2 as far north as the coast of Maine (McKay. Date Unknown). The NYS HMP indicates that damage from this event was estimated at $800,000 in Long Island. Weather 2000 indicates that 2 Coast Guard Cutters and I Navy Destroyer sunk in or near SC during this event. August 25 - September 1, 1954 (Hurricane Carol): Hurricane Carol impacted SC between August 25 and September 1, 1954, with the worst hit areas being Montauk Point, Riverhead, Westhampton and Amagansett (Figure 5-86). On September 2, 1954, Long lsland, including SC, was declared a disaster area after 275,000 homes were left without power (FEMA DR-26). Property loss was estimated at $3 million and as a result of winds of 125 mph and waves as high as 14 feet. Eastern SC bore the full brunt of the hurricane. Average wind speeds at the Westhampton Air Force Base reached 66 mph with gusts hitting 90 mph ("Long Island Hurricane History", Date Unknown). Damage to Townships and Villages in SC include, but were not limited to, the following: · Amagansett: A 300 foot tower of the Mackay radio station was blown over and crashed into the roof of a four car garage. · Montauk Point: The Montauk Point area was closed off for hours by high tide rolling acro§s the neck of Napeague. Water four feet deep and a mile wide poured across Montauk Highway, making Montauk Point a temporary island. About 25 of Montauk's cottages and motels had their roofs ripped off and the sea broke through the dunes and flooded the main road. Approximately 30 boats, mostly private pleasure craft, were blown ashore at Lake Montauk. Forty cabanas at Montauk Surf Club were blown away. Winds as high as 125 mph were recorded at the Montauk Lighthouse. · Riverhead: In the path of the storm's center, in Riverhead, about 40 trees were blown down near the Long Island Station in the right of way, causing railroad service to be temporarily suspended. Riverhead experienced gusts of wind of over 98 mph. · Westhampton: Half a dozen homes were destroyed when the high tide rolled inshore at five or six feet higher then normal.

Hurricane Carol Track in Northeastern U.S. - Maximum Wiud Map Source: Long Island Hurricane History, Date Unknoxvn August 7-19, 1955 (Hurricane Diane): When Hurricane Diane brought heavy rain throughout the northeast, flooding was immediate and devastating. Hurricane Diane was, and still remains, the wettest tropical cyclone on record for the Northeast, causing significant flood and rain damage. Many small rivers rose above their banks from mountain mn-off and flooded towns throughout New England. Flood records were numerous throughout the northeast and damage was high. This even/resulted in a FEMA Disaster Declaration (FEMA DR-45), declared on August 12-19, 1955. According to NYS HMP, this event resulted in millions in damages (not quantified) to property and roads and caused four deaths within southeastern NYS. Monetary losses or damages to SC were not indicated in the documents reviewed. September 9-12, 1960 (Hurricane Donna): Donna holds the record for retaining "major hurricane" status (Category 3 or greater on the Saffir-Simpson Hurricane Scale) in the Atlantic Basin for the longest period of time on record. For nine days, September 2 to September 11, Donna consistently had sustained winds of at least 115 mph. From the moment it became a tropical depression in the Caribbean to when it dissipated after becoming an extratropical storm in Maine, Donna roamed the Atlantic from August 29 to September 14, a total of 17 days. Hurricane Donna made landfall across Long Island, New York on September 12, 1960, as a Category 2 Hurricane. Several stations on Long Island reported sustained winds over 100 mph, and wind gusts of 125 to 130 mph were recorded at the eastern end of the island (Barnes, 1999). Some 10,000 residents of Nassau County's and SC's South Shore were evacuated before the storm hit. Winds averaged 40 to 50 mph, but reached 125 mph off the East End. High tide at Jones Beach swelled to a record 11.7 feet, seven feet above normal. Two Long Islanders were killed in hurricane-related traffic accidents and over 220,000 homes lost electricity before the storm moved northward. Fallen trees, electric wires, and telephone poles were strewn across streets. Approximately 8,500 telephones went out of service. Property damage was estimated in the millions (Blair, 2007). Hurricane Donna was one of the few hurricanes to affect every state along the East Coast; it is one of few storms to produce hurricane-force winds along the east coast from South Carolina to Maine. Fifty people were reported dead in the United States, with damages totaling to $3.04 billion (2004 USD) (Blake et. al., DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.446 DRAFT- September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE 2005). The NYS HMP indicated that damage from this event was estimated at $1.9 million within Long Island. Specific monetary losses or damages to SC were not indicated in the ~naterials reviewed.

Minimal damages were sustained from this event in the Long Island area. Specific monetary losses or dantagcs to SC were not indicated in the information reviewed. August 10~ 1976 (Hurricane Belle): Hurricane Belle threatened much of the east coast of the U.S: Hinderer. the storm weakened before landfall and struck Long Island, New York as a Category 1 hurricane. Although a Category I hurricane, it was the most damaging hurricane to hit Long Island since Hurricane Carol in 1954. Even those damage from this event were less than anticipated, winds of 80 mph were docuntcnted. Combined with heavy rains, the storm resulted in one death and over $100 million in damage I 1976 USD) ($354 million (2006 USD) and received a FEMA Disaster Declaration (FEMA DR- DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-48 DRAFT - September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE 520) on September 3, 1976, which included SC. The greatest impact from Belle was associated with.its rainfall. Four to six inches of rain were recorded throughout New England and the Mid-Atlantic regions. SC experienced approximately six inches of rain. There was considerable small stream flooding and moderate crop damage C'Long Island Hurricane History", Date Unknown). According to LIPA, this event affected over 533,000 customers for a duration of 112 hours for 4.7 days (LIPA, 2004). Figure 5-90.!, Hurricane Belle Sn'uctural Damages~ Note: Westhampton Racquet Club in Westhampton Beach on Dune Road during Hurricane Belle. September 27, 1985 (Hurricane Gloria): Hurricane Gloria affected Long Island as a Category 2 hurricane, with the worst hit areas within eastern Long Island (including Cutchogue (North Fork), Greenport, Westhampton Beach, Lindenhurst, Riverhead, Northport, Babylon, Brookhaven, East Hampton, Huntington, lslip, Shelter Island, Smithtown, Southampton, Southold, Montauk, Fire Island and Shinnecock Bay). Severe power outages resulted for Long Island Lighting Co. (LILCO), with two third of its customers losing power. This was identified as one of worst disasters in utility history taking 11 days to fully restore service. According to LIPA, this event resulted in over 750,000 customers being affected for 11.6 days (LIPA, 2004). The event left more than a million people without power as winds gusted to 100 mph; the hurricane also felled thousands of trees, flooded hundreds of streets, and damaged dozens of shorefront homes. The storm center passed over Fire Island with heavy rain and winds of over 80 mph. Property damages of $285 million were sustained and 48 homes were destroyed on Fire Island. Eleven deaths were reported in Long Island (Long Island Hurricane History, Date Unknown). The strongest winds occurred on eastern Long Island and this was the only location that experienced structural damage (lim!ted and spotty damage occurred). Post-storm analysis of building damage near Westhampton Beach and Fire Island support estimates of peak winds over 110 mph. Figure 5-94 identifies homes with roofs ripped off by the storm. A few locations on eastern Long Island reported modest storm surge damage. Near Babylon, Long Island, tides were measured at 6 feet above mean tide, with flood waters 4-feet deep in living areas. The NWS indicated that Willets Point recorded tides 4.3-feet above normal. Many beach communities on eastern Long Island reported modest beach erosion with several piers and docks swept away. The worst damage during Hurricane Gloria occurred across central and eastern Long Island. This region was located in the area of maximum winds just to the east of Gloria's eye. Most of the spotty structural damage occurred across eastern Long Island, with thousands of trees blown into buildings and across shoreline roads, some roofs ripped off, and modest storm surge flooding. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-49 DRAFT- September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE This event resulted in a FEMA Disaster Declaration (FEMA DR-750), declared on October 18, 2005. According to the NYS HMP, this event resulted in approximately $48.5 million in damages to property within Long lsland; however, additional sources have indicated that recorded monetary losses throughout Long lsland substantially exceeded that amount due to potentially tracking different types of damages and losses. Steve Wick of Newsday indicates that one third of the $300 million in damages throughout the east coast occurred on Long Island; however, this source does not indicate the actual losses accrued in SC. Therefore, these other sources may not be considered reliable for the purpose of this HMP. Specific damage to Townships and Villages in SC included but were not limited to, the following: · Babylon: Damage was heaviest along the town's south shore (Copiague, Lindenhurst, Babylon and W. Babylon). Flooding south of Montauk Highway caused an estimated $2 million in damage to homes along canals that lead to/he Great South Bay. Hundreds of trees fell, bringing down power lines. · Brookhaven: Scattered flooding o&urred along the north and south shores. Several trees and power lines were downed. Eight airplanes from Brookhaven Airport were significantly damaged. The roofs of 2 apartments in Coram were damaged. High winds ripped loose an antenna tower at the County fire coordination's center in Yaphank. · East Hampton: The wind ripped the roofs from several buildings and fanned a fire at a house in Amagansett, which burned to the ground. The roof of Gumey's Inn ripped off, resulting in the destruction of several cars in the parking lot. · Huntington: Dangling wires ignited small fires and fallen trees blocked roads. Five foot waves were reported at Crab Meadow Beach and some Asharoken residents left home as water flooded onto Asharoken Avenue. Several boats were swamped in Huntington and Centerport Harbor. · Islip: Heavy damage occurred south of Montauk highway, including several wires and utility poles and transformer units which were felled. It was estimated that it would take 2-3 days to address the impacts. In Islip Terrace, wind gusts of over 100omph ripped the roof off the lslip Police Station and the large hangers at Long Island MacArthur Airport (Figure 5-94). · Lindenhurst: LILCO shut off gas service to 500 customers in Lindenhurst south of Montauk Highway because of flooding related to the storm. · Riverhead: A local man died during the cleanup of a fallen tree. · Shelter Island: Many trees were downed and fallen power lines ignited several minor brush fires (no major damage occurred). · Southampton: Many trees and wires were downed. Erosion occurred. The Ponguogue Bridge in Hampton Bays was submerged by flood waters. Dune Road was under six to eight feet of water. There was significant building damage in the Westhampton Beach area, with many structures flattened. · Southold: Many trees and wires were downed. Orient was separated from the mainland for most of the storm. At Fisher Island, 40 persons fled their homes, taking shelter in a World War II bunker. · Smithtown: Many trees and wires were downed, leaving many streets impassable. Broken windows were reported and at least one building lost a portion of its roof (www. Hurricanes- Blizzards-noreasters.com).

August 16-29, 1991 (Hurricane Bob): Hurricane Bob impacted SC on August 16-29, 1991, with the worst hit areas being Montauk, Riverhead, Northfork/Southfork, E. Moriches, Sag Harbor to Bayville (North Shore), Port Jefferson, Northport, Centerport, Dering Harbor, Huntington, Greenport, Shinnecock Hills, East Hampton, East Quogue, Southampton, Fire Island, Babylon, Bellport, Medford, Center Moriches and Islip. Agricultural lands within SC were significantly compromised. Hurricane Bob caused an estimated $780 million in damage to the region, with $11.8 million damages to Long Island. It knocked out nearly l/3rd of LILCO customers, with 75% of the outages being in the five East End towns of SC. According to LIPA, this event resulted in over 477,765 customers affected for a duration of 112 hours for 4.7 days (LIPA, 2004). The storm knocked out 21 high voltage transmission lines, 14 substations, and 72 lower voltage distribution lines. Hundreds of smaller wires were downed by trees and electric poles. Boats across the island suffered. Road and bridges were closed including Meadowbrook, Wantagh Parkways and the Robert Moses Bridge (Long Island Hurricane History, Date Unknown). This event resulted in a FEMA Disaster Declaration (FEMA DR-918), declared on September 16, 1991. According to NYS HMP, this event resulted in approximately $11.7 million in damages to property within Long Island. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-52 DRAFT - September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE This event created erosion on Dune Road and the barrier beaches. A least l/6th of SC's total annual agricultural output (valued at approximately $120 million), appeared to be wiped out or severely damaged by the storm (including cornfields, peach and apple trees). Allstate Insurance, the largest insurer of cars and homes on the Island, expected 7,000 to 10,000 claims to be filed and projected claims of $6 to $7 million. Police overtime during and afer the storm cost an estimated $80,000. Officials expected millions in damages to wrecked boats in East End towns. The North Shore proved to be the worst impacted, with boaters as far west as Bayville deal experiencing damaged crafts and docks. Trees were downed virtually every few yards for miles throughout Southampton, East Hampton, and Amagansett. The Long Island Rail Road suspended services to the East End (Long Island Hurricane History, Date Unknown). Damage to Townships and Villages in SC included, but were not limited to, the following: · Center Moriches: One person went missing (presumed drowned) off coast by Great Gun Beach, between Smith Point and Moriches Inlet at the Fire Island National Seashore. · East Hampton: Up to 4,000 people sought shelter in East Hampton. Three Mile Harbor had a. large number of beached vessels. More than a dozen sailboats were beached. One tree struck the historic windmill, tearing part of it down. East Hampton high school was used as a refuge for residents. · Fire lsland: Along the bay side of Fire Island, about 15 boats were beached from Davis Park and to the west. · Huntington: In the Northport area, Coast Guard Seaplane VI70 was forced down on Northport Bay, which was damaged from take-off from Floyd Bennet Field. Boats bobbed like beer cans on the water. At least 100 boats were damaged, including 12 that were severely damaged. In Huntington Bay, many boats were destroyed and/or sank. · Medford: Two car accidents caused a death when traffic signals were out at the corner of Granny Road and County Road 83 in Medford. · Montauk: The highest gusts of wind were 88 mph and occurred 10 miles west of Montauk Lighthouse. Waves were reported as high as 25 feet in the ocean and 6 inches of rain fell in East Hampton. · Port Jefferson: At the Port Jefferson Marina, more than half of the 110 boats were damaged by collision and four sank. · Sag Harbor: Every marina suffered damages to docks and boats and the village municipal building was flooded when the windows blew out. As many as 50 boats were damaged, and the village lost a new $50,000 floating dock. · Shelter lsland: Dering Harbor had a large number of beached vessels, including more than 10 sailboats were beached. With Hurricane Bob's winds striking from the north, Dering Harbor was directly hit. About 80 boats were blown off their moorings, into each other and onto the beach. · Southampton: A 150oyear old, 60-foot oak tree smashed down across a resident's fence, and South Main Street in Southampton. · Southold: In Greenport, firefighters filled the Regina Marls in Greenport in an attempt to save the vessel. The Regina Marls was one of the last remaining tall ships brought to the harbor to be restored. While all of North Fork was without power, Greenport had the only gas pumps working at Mr. Robert's Convenience Store. These pumps were the only ones working from Greenport to Orient Point (Long Island Hurricane History, Date Unknown).

July 19, 1996 (Tropical Storm Bertha): As Bertha snaked up the eastern seaboard over land, she weakened before reaching Long Island Coastline. This event affected Long Island as a tropical storm DRAFT - September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE with average wind speeds of 60 mph. It left 89,000 LILCO customers without power and knocked down hundreds of trees. The highest wind gusts were reported by spotters in Western SC, ranging from 49 mph at West lslip to 74 mph at Babylon Village (Long Island Hurricane History, Date Unknown). September 16, 1999 (Hurricane/Tropical Storm Floyd): Hurricane Floyd was the third major hurricane in the 1999 Atlantic hurricane season. There is debate amongst climatologists as to whether Hurricane Floyd made landfall as a Category I or as a very strong "ahnost hurricane strength" tropical storm, the official records note it as the latter. By the time this hurricane made landfall, it was significantly weaker than it was at sea, creating little inland damage. However, Floyd produced torrential rains and high winds throughout the Mid-Atlantic, as far north as NY City and Long Island. Some 1,260,000 citizens across the Mid-Atlantic States lost power because of the storm. According to LIPA, this event affected over 149,000 for a duration of 1.5 days (LIPA, 2004). The storm also was one of the costliest in the nation's history, amounting to $4.5 billion across the U.S. ( 1999 USD; $5.7 billion in 2004 U.S. dollars). Most of the deaths and damage were from inland, freshwater flooding in eastern North Carolina (NWS NHC, 2005). This event resulted in a FEMA Disaster Declaration (FEMA DR-1296), which included SC. According to FEMA and the NYS HMP, approximately $62.2 million in damages to property were reported for 12 counties in eastern NYS from this event. Governor Pataki indicated that more than $1.5 million in recovery aid was issued to 34 NY municipalities. Approximately $169,000 in disaster aid was issued to Huntington, Asharoken, and Patchogue.

Bands of torrential rain produced widespread and significant flash flooding of low lying and poorly drained areas, including streets, basements, roofs, and ceilings, as well as small creeks throughout Nassau and Suffolk Counties. Several trees and power poles were leaning due to soggy ground. Preliminary damage estimates were $22 million for Long Island. A SC News Release on October 27, 2005, indicated that early and mid-October severe storms and · flooding from the remnants of Hurricane Wilma created $43 million in damages to the County. Over 6,000 residents reporting damages totaling nearly $23 million; $6.5 million in losses to agriculture and $14 million in losses to municipalities were recorded. Over 6,300 SC residents reported structural damage, primarily including: basement flooding and damage to heating and hot water systems (Levy, 2005). According to NY Congressman Tim Bishop (November 30, 2005), this event caused the south shore of Long Island, particularly large portions of SC, to experience massive flooding and significant storm damage (including erosion). Tim Bishop requested assistance in response to the torrential rains and wind storms that wreaked havoc across Long Island in October, especially SC. Bishop's letter followed emergency declarations to SC and NYS. Nearly two feet of rain fell over the course of fifteen days in SC, ending with a spectacularly devastating impact from the combined force of the season's first nor'easter DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-56 DRAFT - September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE and remnants of Hurricane Wihna. An estimated 6,000 homes in SC were reported damaged, while the County's infrastructure estimated nearly $8 million in damages (Farber, 2005). September 2, 2006 (Tropical Storm Ernesto): On September 2, 2006, more than 30,000 customers on Long Island lost power due to impacts associated with the remnants of Tropical Storm Ernesto. This storm hammered the SC region, also causing flooding and beach erosion. Most damages and power losses were reported in Hempstead and Babylon (Gardner, 2006). ProbabiliD, of Future Eveuts NOAA's National Hurricane Center Risk Analysis Program has calculated hurricane MRPs for the northeastern U.S. for the five hurricane categories (see Figure 5-100 for a Category 3 hurricane). Table 5- 10 documents the estimated return periods for Categories I through 5 that may impact SC. Figure 5-100. Retum Period for Category 3 Hurricanes Figure 5-101.

DRAFT- September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE Hurricane return periods reflect the probability that various categories of hurricanes can be expected within 75 nm (86 statute miles) of a given location. In simpler terms, a return period of 20 years for a Category 3 or greater hurricane means that on average during the previous 100 years, a Category 3 Or greater hurricane passed within 75 nm (86 miles) of that location about five times. Therefore, it can be expected, on average, that an additional five Category 3 or greater hurricanes within that radius over the next 100 years. The data used for the return period maps above is produced by the National Hurricane Center Risk Analysis Program (HURISK) by Charles Neumann. Table 5-25.

Map not to scale. Earlier in this section, the identified hazards of concern for the SC were ranked. The NYS HMP conducts a similar ranking process for hazards that affect the State. The probability of occurrence, or likelihood of the event, is one parameter used for ranking hazards. Based on historical records and input from the Planning Committee, the probability of occurrence for hurricanes in SC is considered occasional [hazard event that occurs from once in 10 years to once in 100 years (104/yr to 10-2/yr), as presented in Table 5-4]. It is estimated that SC and all of its jurisdictions will continue to experience the direct and indirect impacts of hurricanes/tropical storms annually that may induce secondary hazards such as utility failure and transportation accidents. In addition, given the location of the study area, impacts can be expected to be significant when major events occur (see vulnerability assessment below). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-59 DRAFT - September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. For hurricanes, SC has been identified as the hazard area. Therefore, all assets in SC (population, structures, critical facilities and lifelines), as described in the County Profile section, are vulnerable. The following text evaluates and estimates the potential impact of severe storms on SC including: · Overview of vulnerability · Data and methodology used for the evaluation · Impact, including: ( 1 ) impact on'life, safety and health of county residents, (2) general building stock, (3) critical facilities, and (4) economy · Further data collections that will assist understanding of this hazard over time · Overall vulnerability conclusion Over,, ;ew of ~r uh~erabthty The high winds and air speeds of a hurricane often result in power outages, disruptions to transportation corridors and equipment, loss of workplace access, significant property damage, injuries and loss of life, and the need to shelter and care for individuals impacted by the events. A large amount of damage can be inflicted by trees, branches, and other objects that fall onto power lines, buildings, roads, vehicles, and, in some cases, people. Additionally, hurricanes can cause storm surge related damages along the coast. Due to SC's coastal location, the loss associated with hurricanes is primarily associated with hurricane- related rains (see flooding discussion), storm surge and severe winds. The County has experienced flooding in association with hurricanes and tropical storms in the past. Please refer to the flood hazard profile for more information on the County's vulnerability to this hazard. The entire inventory of the County is at risk of being damaged or lost due to impacts of severe wind. Certain areas, infrastructure, and types of building are at greater risk than others due to proximity to falling hazards, their manner of construction. Potential losses associated with high wind events were calculated for SC as a whole and each participating jurisdiction for two probabilistic hurricane events, the 100-year and 500-year MRP hurricane events. The impacts on population, existing structures and critical facilities are presented below, following a summary of the data and methodology used. Data aud Methodology After reviewing historic data, the HAZUS-MH methodology and model were used to analyze the hurricane hazard for SC. Data used to assess this hazard include data available in the HAZUS-MH hurricane and flood model, professional knowledge, information provided by the County's Planning Committee, and input from public citizens. In HAZUS-MH, a wind study was conducted for the County as a whole as well as for each participating jurisdiction for 100o and 500-year MRP events. This was necessary because no single storm can cause damage throughout a large study region such as SC. For example, a 100-year MRP event run for the County as a whole, may only cross the eastern side of SC and have little impact on a western SC (i.e., DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-60 DRAFT- September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE Town of Babylon). Therefore, each participating jurisdiction was set up as a separate study region in HAZUS-MH and a probabilistic 100- and 500-year MRP event model was run. This methodology provides a more realistic probabilistic analysis and accurate return period results for each participating jurisdiction. Loss estimates and peak wind speeds are reported for each participating jurisdiction's model run and should not be added together to obtain a total for the County. A separate probabilistic 100- and 500-year MRP event was also modeled for the County as a whole, and these loss estimates and wind speeds should be used to assess total County estimates. Figures 5-46 through 5-68, earlier in this section, show the maximum peak wind speeds that can be anticipated in the study area associated with the 100o and 500-year MRP hurricane event for each participating jurisdiction and the County as a whole. The estimated hurricane track for the 100- and 500- year event is also shown. HAZUS-MH contains data on historic hurricane events and wind speeds. It also includes surface roughness and vegetation (tree coverage) maps for the area. Surface roughness and vegetation data support the modeling of wind force across various types of land surfaces. Hurricane and inventory data available in HAZUS-MH were used to evaluate potential losses from the 100- and 500-year MRP hurricane event (severe wind impacts). Locally available inventory data were reviewed to dctermine their appropriateness for inclusion. Other than data for critical facilities, the default data in HAZUS-MH was the best available for use in this evaluation. The 11 residential and 10 commercial occupancy classes available in HAZUS-MH were condensed into the following occupancy classes (residential, commercial, industrial, agricultural, religious, government, and educational) to facilitate the analysis and the presentation of results. Residential loss estimates address both multi-family and single family dwellings. In addition, impacts to critical facilities were evaluated for the 100-year and 500-ycar MRP events. Hurricanes cause both wind and storm surge related damages; however, currently HAZUS-MH only analyzes the flood and wind models separately, producing independent results. In addition to analyzing and reporting wind-only loss estimates for each participating jurisdiction and the County as a whole, an attempt was also made to combine these hazards and produce wind and storm surge loss estimates for a probabilistic hurricane using HAZUS-MH. This methodology involved both running a probabilistic hurricane analysis and setting up a coastal flood probabilistic scenario using the surge height(s) as the Stillwater Elevation (SWEL). For each Census block, the storm surge and wind damages were compared and the larger damage value for building structure and contents is estimated as the minimum damage sustained for each general occupancy type. The storm surge damage was added to the wind damage and compared to the total inventory value. If the damage total is greater than the inventory total, the inventory total is the maximum damage sustained. If the damage total is smaller than the inventory total, the damage total is the maximum value. Therefore, the combined hurricane wind and storm surge damage results are presented as minimum and maximum value range. Impact on Life, ltealth and Safet) The impact of a hurricane on life, health and safety is dependent upon several factors including the severity of the event and whether or not adequate warning time was provided to residents. It is assumed that the entire County population is exposed to the hurricane hazard. Please refer to Table 4-3 in the County profile section for the total SC population vulnerable to this hazard. SC is densely populated along its coastal shores. SEMO has published a digital version of the U.S. Army Corps of Engineers "New York State Hurricane Evacuation Study - Inundation Maps" (1993) of the hurricane storm surge inundation zones for SC. The 1993 inundation maps were based on surge height projections calculated by the National Weather Service's "Sea - Lake Overland Surge from Hurricanes - SLOSH Model." The surge heights were calculated for a number of category 1-4 hurricanes. This data was DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-61 DRAFT- September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE developed to delineate hazard zones and assess risk from hurricane-related storm surges and to support hurricane evacuation planning. Table 5-26 sulnmarizes the population located in the hurricane inundation zones based on 2000 Census data. See the Flood profile for the population located in the coastal flood zones (V-zones).

Residents may be displaced or require temporary to long-term sheltering in the event of a hurricane. In addition, downed trees, damaged buildings and debris carried by high winds can lead to injury or loss of life. Socially vulnerable populations are most susceptible, based on a number of factors including their physical and financial ability to react or respond during a hazard and the location and construction quality of their housing. According to the 2000 Census, greater than 11% of the County's total population is 65 years of age and above. Table 5-27 estimates the number of households that may be displaced and/or require temporary shelter due to a 100-year and 500-year MRP event. Table 5-28 estimates the debris produced for 100- and 500- year MRP events. These estimates are based on a wind-only HAZUS analysis. Because the estimated debris production does not include storm surge or flooding, this is likely a conservative estimate and may be higher if multiple impacts occur.

Potential damage is the modeled loss that could occur to the exposed inventory, including damage to structural and content value based on the wind-only impacts associated with a hurricane, followed by a consideration of wind and storm surge impacts (using the methodology described earlier). Wind Only Hurricane Impacts The entire study area is considered at risk to the hurricane wind hazard. Please refer to Table 4-7 in the County Profile which presents the total exposure value for general building stock by occupancy class for SC.

There are an estimated 9,352 buildings across all occupancy classes that will be completely destroyed, of which 99% are residential buildings. A 100- year event, as described earlier in this profile equates to a Category 3 hurricane. For the 500-year MRP wind-only event, HAZUS-MH estimates over 65% of the total number of buildings in SC (302,231 buildings) will be at least moderately damaged. In addition, HAZUS-MH estimates 91,345 buildings will be completed destroyed. Of the buildings estimated to be completely destroyed, 91,210 are residential or 20% of the residential building stock. The 500-year MRP wind speeds equate to a Category 4 hurricane. Residential buildings comprise the majority of the building inventory and are estimated to experience the majority of building damage. Tables 5-31 and 5-32 summarize the building value (structure and contents) damage estimated for the 100- and 500-year MRP hurricane wind-only events.

The majority of these losses are to the residential building category. Because of differences in building construction, residential structures are generally more susceptible to wind damage than commercial and industrial structures. The damage counts include buildings damaged at all severity levels from minor damage to total destruction. Total dollar damage reflects the overall impact to buildings at an aggregate level. Of the $164.6 billion in total residential replacement value (structure and contents) for the County (refer to Table 4-6 in the County Profile), an estimated nearly $10 billion in residential building damage can be anticipated for the 100-year event and nearly $59 billion in residential building damage can be anticipated for the 500-year event. In other words, residential building damage accounts for approximately 90% and 87.5% of total damages for the 100- and 500-year wind-only events, respectively. These results are estimates from the County HAZUS-MH run. Similarly, residential buildings also account for the majority of estimated damages for 100o and 500-year events run for each participating jurisdiction in HAZUS-MH. For specific dollar losses estimated for each jurisdiction, please refer to Tables 5-31 and 5-32. This illustrates that losses can be significant, especially to residential structures. Figures 5-103 through 5-106 show the density of damage estimated for residential and commercial structures for the 100-year and 500-year MRP wind events run for the County as a whole. As can be seen from the figures, the density of loss to residential buildings is significant for the hurricane-related wind impact.

Table 5-33 smmnarizes the damage estimated for the 100- and 500-year MRP hurricane related winds and storm surge for all occupancy classes (total), residential and commercial occupancy classes. A minimum and maximum damage value range is reported. Damage estimates are reported for each jurisdiction's HAZUS-MH model run. To assess total County damages, refer to the estimates listed in the row labeled "Suffolk County." Similar to the wind-only results, expected building damage was evaluated by HAZUS across the following wind damage categories: no damage/very minor damage, minor damage, moderate damage, severe damage, and total destruction. Table 5-30 summarizes the definition of the damage categories. As described in the methodology section, a coastal flood probabilistic scenario using the surge height(s) as the Stillxvater Elevation (SWEL) was also set up. For each Census block, the storm surge and wind damages were compared and the larger damage value for building structure and contents is estimated as the minimum damage sustained for each general occupancy type. The storm surge damage was added to the wind damage and compared to the total inventory value. If the damage total is greater than the inventory total, the inventory total is the maximum damage sustained. If the damage total is smaller than the inventory total, the damage total is the maximum value. Therefore, the combined hurricane wind and -storm surge damage results are presented as minimum and maximum value range. Table 5-33 summarizes the estimated minimum and maximum building value (structure and contents) damaged by the. 100-Yr. and 500-Yr. MRP hurricane-related winds and storm surge.

The majority of these losses are to the residential building category. Of the $164.6 billion in total residential replacement value (structure and contents) for the County, an estimated $10 billion to nearly $12 billion in residential building damage (structure and contents) can be anticipated for the 100-year event. These results are estimates from the County HAZUS-MH run. Using the maximum damage value estimate, this is nearly $2 billion more than estimated damages for the wind- only analysis for the 100-year event. Nearly $59 billion to $63 billion in residential building damage (structure and contents) is estimated for the 500-year event. Using the maximum damage value estimate, this is approximately $4 billion more than estimated damages for wind-only analysis for the 500-year event. Similar to the wind-only analysis, residential buildings comprise the majority of the building inventory and total building value loss for the 100- and 500-year MRP combined wind and storm surge events. One type of residential building particularly vulnerable to the hurricane hazard is manufactured homes (trailer homes). HAZUS-MH indicates there are 5,001 mobile homes located in Suffolk County. The 2000 U.S. Census indicates that there are 5,374 mobile homes in Suffolk County. Figure 4-56 in the County Profile illustrates the distribution of mobile homes in SC. Impact on Critical Facilities HAZUS-MH estimates the probability that critical facilities may sustain damage as a result of a 100-year and 500-year MRP wind-only event. Additionally, HAZUS-MH estimates the loss of use for each facility in number of days. The complete list of critical facilities impacted by the 100-year and 500-year MRP events identified by HAZUS-MH was submitted to the County and participating jurisdictions. Table 5-34 summarizes the number of critical facilities HAZUS-MH identifies that may sustain wind-only damage and/or loss of use due to a 100-year and/or 500-year MRP event. This count includes facilities damaged at all severity levels from minor damage to total destruction. The flood hazard profile discusses the number of critical facilities HAZUS-MH identifies that may sustain damage and/or loss of use due to the 100-year and/or 500-year MRP flood events and indicates whether the facility is located in the coastal (V) zone.

OMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.4-214 SECTION 5: RISK ASSESSMENT - HURRICANE As listed in Table 5-34, there are numerous critical fiacilities impacted by the wind hazard. Specific findings are considered sensitive at this time and will be used by County and Town personnel to identify appropriate mitigation actions. At this time, HAZUS-MH does not estimated losses to transportation lifelines and utilities as part of the hurricane model. Transportation lifelines are not considered particularly vulnerable to the wind hazard; they are more vulnerable to cascading effects such as flooding, storm surge, falling debris etc. hnpacts to transportation lifelines affect both short-term (e.g., evacuation activities) and long-term (e.g., day-to-day commuting) transportation needs. The SC Hurricane/Coastal Storm Emergency Response Plan (revised 2002) outlines evacuation levels, agency roles, and addresses sheltering and special needs populations. This Emergency Response Plan and the Comprehensive All-Hazards Emergency Management Plan for SC (March 2005) identify areas of greatest concern (Fire Island) and critical transportation routes for evacuating areas of greatest risk to a hurricane's impact. These routes are: (1) Route 25 and Cross River Drive intersection, east of Riverhead; (2) Sunrise Highway (Route 27) and North Sea Road intersection, Southampton; (3) Route 111 (lslip Avenue) and Southern State Parkway interchange; (4) Nugent Road and West. Main Street interchanges with Long Island Expressway, west of Riverhead; (5) Montauk Highway (Route 27), east of Southampton; (6) Wellwood Avenue and Sunrise Highway (Route 27), north of Lindenhurst; and (7) ferry service out of/to Fire Island. Utility structures could suffer damage associated with falling tree limbs or other debris. Such impacts can result in the loss of power, which can impact business operations and can impact heating or cooling provision to citizens (including the young and elderly, who are particularly vulnerable to temperature- related health impacts). impact on Economy Sufficient information was not available to perform a detailed assessment of estimated losses to the economy. Instead, economic loss as summarized in the HAZUS-MH Hurricane Event Summary Report for the 100- and 500-year MRP wind-only events is described below. It is estimated that the impact to the economy, as a result of a hurricane event, would be considered "high" in accordance with the risk ranking shown in Table 5-5. Hurricane events can impact the economy, including: loss of business function, damage to inventory, relocation costs, wage loss and rental loss due to the repair/replacement of buildings. HAZUS-MH estimates the total economic loss associated with each hurricane MRP event which includes building- related losses (direct building losses and business interruption losses) based on the available inventory. Direct building losses are the estimated costs to repair or replace the damage caused to the building. This is reported in the Impact on General Building Stock section discussed earlier. Business interruption losses are the losses associated with the inability to operate a business because of the damage sustained during the hurricane event. For the 100-year MRP hurricane event, HAZUS-MH estimates a loss of over $12 billion; a majority of which is associated with direct building losses (mainly residential loss). Only one percent of the estimated losses were related to the business interruption of the region. For the 500-year MRP hurricane event, HAZUS-MH estimates a loss of $74 billion. Similar to the 100-year event, only 1% of the estimated losses were related to the business interruption of the region and the largest loss was sustained by the residential occupancies which made up over 86% of the total loss. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-215 DRAFT- September 2007 SECTION 5: RISK ASSESSMENT - HURRICANE Additional Data and Next Steps Over time, the County will obtain additional data to support the analysis of this hazard. Data that will support the analysis would include additional detail on past hazard events and impacts, specific building information such as first floor elevation, type of construction, foundation type and details on protective features (e.g., hurricane straps). In addition, information on particular buildings or infrastructure age or year built would be helpful in future analysis of this hazard. In time, HAZUS-MH will be released with modules that address hurricane wind and associated flooding as one model. As this version of HAZUS-MH is released, SC can run analyses for an overall picture of the hurricane-associated wind and flood damages. Overall Vulnerability Assessment SC is highly vulnerable to hurricane events which can cause significant impacts and losses to the County's structures, facilities, utilities, and population. Existing and future mitigation efforts should continue to be developed and employed that will enable the study area to be prepared for these events when they occur. The overall hazard ranking determined by the Planning Con'unittee for this hazard is high (see Tables 5-6 and 5-7). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.4-216 DRAFT- September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION 5.4.5 COASTAL EROSION This section provides a profile and vulnerability assessment for the coastal erosion hazard. IIAZARD PROFILE This section provides profile information including description, location and extent, previous occurrences and losses and the probability of future occurrences. Description According to the NYS Department of Environmental Conservation (NYS DEC) Rules and Regulations (6 NYCRR Part 505.2 - Coastal Erosion Management), coastal erosion means the loss or displacement of land along the coastline due to the action of waves, currents, tides, wind-driven water, waterbome ice, or other impacts associated with storms. It also means the loss or displacement of land due to the action of wind, runoff of surface waters, or groundwater seepage. The principal natural causes of erosion are wave action, wind action, and overland runoff groundwater seepage through intense precipitation and natural sorting of beach sediment through loss of fines. Other contributing factors that can significantly increase erosion of a natural protective feature include length of fetch (length of water over which a given wind has blown), wind direction and speed, wave length, height and period, nearshore water depth, tidal influence, increased lake or sea levels, overall strength and duration of storm events and variability in sediment supply to the littoral zone. Combinations.of these factors and events can exacerbate the effects of these processes by increasing water levels, storm rise, wave run up and wind setup, producing damaging waves, driving ice "plates" along the shore scouring beaches and bluff areas, reducing sand . from beaches, and allowing water and wave action further inland that intensifies erosion of dunes and bluffs tNYS DEC). In addition, erosion can be exacerbated by man-made influences, such shoreline hardening, seawalls, groins, jetties, navigation inlets, boat wakes, dredging and other interruptions of physical coastal processes which reduce or interrupt longshore sediment transport. Primal' forms of coastal erosion include beach erosion, dune scarping/dune erosiom overwash, and bluff erosiom as described below: · Beach Erosion: A beach is the accumulation of sand, gravel, silt or clay located at the transition zone between land and water. Beach erosion occurs through the removal of beach sediment caused by wind, wave action and longshore cut'rents, causing offshore movement of sand from the sub-aerial beach during storms. Beach erosion is a recurring, long-term problem and it is a precursor of dune erosion, dune overwash, bluff erosion, failure of shoreline protection structures and destruction of shoreline development. Examples of beach erosion have been recently found in Smith Point County Park, and just west of Shinnecock lnlet. Former beach erosion, which has since improved, was found at Robert Moses State Park and along Westhampton Beach within the past. · Dune Erosion/ScarpinA: A dane is a hill of sand built by wind-related or man-made processes found in deserts or near lakes and oceans. Dune erosion is caused by wave-attack during a storm or a large swell or by wind action. This process, generally known as scarping, releases sand thaf was stored in the dune to the active beach or to the zone just landward of the dune. The influx of this dune sand to the active beach is often carried offshore to build temporary sand bars, which he[p attenuate incoming wave energy and can assist in post storm low profile beach recovery. Dune erosion is common along segments of the southern shoreline of SC where fronting beaches have been depleted, e.g. sections of Fire Island. DMA 2000 H~'z~rd Miiigation Pia~ £ SUff°i~ 6g~h~y, New York 5.4.5-1 DRAFT - September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION Overwash/Washover: Overwash/washover are terms related to the transport of sediment landward of the active beach, which occurs from coastal flooding during a tsunami, hurricane, nor'easter or other event with extreme waves. Overwash occurs where the flow of water (from wave and storm surge) over the upper part of the beach profile causes beach sediment, to advance over the crest of the beach, dune or berm and where this beach sediment does not directly return to the generating water body such as ocean, sea, bay or lake after water level fluctuations return to normal. There are two kinds of overwash: overwash by run up and overwash by inundation. Overwash begins when the run up level of waves, usually coinciding with a storm surge, exceeds the local beach or dune crest height. As the water level in the ocean rises such that the beach or dune crest is inundated, a steady sheet of water (called sheetwash) and sediment runs over (overwashes) the barrier. Washover is the sediment deposited inland of a beach by overwash. Washover can be deposited onto the berm crest or as far as the back barrier bay, estuary, or lagoon (USACE, 2004). Dune erosion is common along segments of the southern shoreline of SC where fronting beaches have been depleted (e.g., sections of Fire Island). Bluff Erosion: A bluff is a cliff with a broad face, or a relatively long strip of land rising abruptly above surrounding land or water. Typically, it rises at least 25 feet above the water body at an average slope of 30 percent or greafer. Bluff erosion is the erosion of these cliffsides or broad faces as a result of high waves, wind, groundwater or surface runoff and can lead to significant loss of land to the sea. Bluff erosion takes place from the top of the bluff down to the sea. Several processes can lead to erosion on bluffs. Groundwater can leak out the face of a bluff to create wet areas that wash sediments down the bluff face. Surface water may flow directly over the face of a bluff or down a gully on a bluff and carry soil and sediment to the sea. Seasonal freeze-thaw cycles can loosen sediment in a bluff that slumps downhill in the spring. At the base of the bluff, high tides, coastal flooding and wave action can scour the bluff toe to remove sedimqnt and undercut the slope. Oversteepened slopes can move downward under the pull of gravity. Coastal bluffs can be affected by all of these processes to some extent. The rate of bluff erosion may vary from one location to the next. Over time, erosion is often episodic with significant land loss one year and less the next. Bluff erosion leads to net land loss and the landward migration of the shoreline as well as the top of the bluff. Actively eroding bluffs are unstable and potentia!ly unsafe for development near the bluff top (Maine Geological Survey, 2005). Bluff Erosion is a long term problem along the stretches of the North Shore of SC, particularly in Asharoken, Rocky Point to Wading River, along Smithtown Bay, Bayville, Sands Point, Kings Point and east of Mattituck Inlet. Where bluffs were unprotected, they were undercut more quickly by wave action where fronting beaches had been washed away. Erosion can impact beaches, dunes, bluffs, barriers, bays, cliffsides, wetlands, marshes, parks, and other natural landforms and can lead to destructive forces upon nearby manmade structures. One of the major impacts of erosion processes is the permanent breaching or creation of inlets along barrier beaches and islands. An example of this is the creation of the Shinnecock and Moriches Inlets along SC's South Shore. Impacts associated with new inlets could include (1) increased flooding and erosion on the mainland shoreline due to increased water levels and wave action in the bays, (2) changes in shoaling patterns, water circulation, temperature and salinity that could significantly alter existing bay ecosystems, and (3) disruption of the longshore transport of sand along the ocean shoreline that would result in increased downdrift erosion. It is noted that these stabilized inlets do provide benefits for recreational and commercial navigation, which is the trade-off. There are a variety of natural- and human-induced factors that influence the erosion process. For example, shoreline orientation and exposure to prevailing winds, open ocean swells and storm surges, and waves all influence erosion rates. Beach composition influences erosion rates as well. For example, a DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.5-2 DRAFT- September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION beach composed of a finer sand and silt is easily eroded compared to beaches primarily consisting of course sand, boulders, gravel or large rocks, which are more resistant to erosion. Other factors may include: · Shoreline type · Geomorphology of the coast · Structure types along the shoreline · Density of development · Amount of encroachment into the high hazard zone · Proximity to erosion inducing coastal structures · Nature of the coastal topography · Elevation of coastal dunes and bluffs · Shoreline exposure to wind and wavks The causes of erosion are often difficult to determine and usually require a skilled interpretation of the processes and activities affecting a particular area. However, common contributing factors to coastal erosion include, but are not limited to, the following: Coastal Storms (Tropical and Extra-tropical) · Human Influence / Intervention (Poor land use practices, failed erosion control methods) · Reduction in Sand/Sediment Supply (through littoral sand transport, sand mining, weather patterns) · Rising Sea Levels (potentially exacerbated by global warming) These contributing factors to erosion are described below. Coastal Storms Coastal erosion is often attributed to major storm events, and in particular to those storm events where high wave energy, strong on-shore winds, and heavy rainfall coincide with a high tide. Large storm- generated waves from hurricanes, nor'easters, or other storms often expedite coastal erosion processes, when wave action is high and water levels and coastal currents rapidly increase. Coastal erosion may change the shoreline over time through the long-term losses of sediment and rocks, or in other cases, may temporarily redistribute coastal sediments; erosion in one location may result in accretion (deposition of sediments) nearby. Deposition is the placement of sediment transported by wind, water, or ice. The impact that waves have along the coastline is dependent upon storm surge. Storm surge is an elevation of water levels, including tides due to lower barometric pressure associated with a hurricane or extra-tropical storm, and wind stress in front of such strong storms which pushes water toward the shoreline. Storm surges contribute substantially to the coastal erosion process, which is further discussed earlier in this section (Section 5.4.4 Hurricanes). The three most important factors contributing to beach and dune erosion during storms are (1) storm surge heights, (2) storm surge duration, and (3) wave steepness (ratio of wave height to length) (Aquilino et. al., 1990). The fast moving nature of a hun'icane in northern latitudes means that the storm surge can be short lived, usually lasting less than a complete tidal cycle. DMA ~000 Hazard Miiigatio~ Pian- Suffolk county, New York DRAFT- September 2007 5.4,5}3 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION The impacts of storm surge are most severe if the storm surge coincides with high tide. Fortunately, the marine shoreline of most of New York has not had significant erosion and flooding damage from recent hurricanes that impacted the NY area as it has had in the past because the time of maximum storm surge coincided with lower tides or hurricane strength was not as great. Extratropical storms (nor'easters) are less intense but can have localized wind velocities that reach hurricane strength. These are slow moving stunts and the effects of these storms are generally present in an area for several days (unlike hurricanes) impacting landscapes much like hurricanes. The primary reason for their ability to alter a shoreline is their duration within an area. Unlike hurricanes that many times have a general duration of 6 hours, nor'easters may remain for a much longer period of time, thus allowing the high waves and storm surges to modify coastal morphology over several complete tidal cycles. Waves and high water generated during the March 1962 Nor'easter effectively altered the shoreline for 5 to 8 tidal cycles resulting in numerous washovers and the formation of a new inlet through Westhampton Beach. Other examples of such storms include the Nor'easter of 1992 and the recent April 2007 Nor'easter which are further discussed in this hazard profile (Cuomo, 1994). Human Influence / Intervention Another contributing factor to erosion-related problems is human intervention. Even though natural events play a major role in the erosion process, human actions can intensify or exacerbate the effects of these processes speeding the erosion process through poor land use methods, dredging operations, vegetation removal, construction of shoreline structures (for example, homes, boardwalks, piers, recreational structures), and misguided erosion control efforts. The mid-atlantic coast, which extends from New York to Virginia, is the most urbanized shore in the country, with millions of people using the shore for recreational or residential purposes. Significant coastal growth in these areas includes the desire to build along the coast line. As a result, there has been a coastal building boom of all types of structures; construction in these areas can increase the potential for coastal erosion by disturbing the natural coastline and also increases the inventory exposed to the coastal erosion hazard (Aquilino, 1990). Humans contribute to the erosion process by removing vegetation which then allows wind and precipitation to directly erode the soil, directing runoff from streets, parking lots, roofs, and other locations (e.g., over a bluff and causing erosion). Humans also alter the coastline by constructing "hardened" structures on the shore, which blocks littoral processes and can reflect wave energy onto adjacent shoreline areas or cause deepening of the nearshore area. Many development activities damage or alter natural protective features and the protection that these features afford the upland area from erosion and storm damage. These problems are contributed by: · Building without considering the potential for damage to properly, · Activities which destroy natural protective features such as dunes or bluffs, and their vegetation are undertaken, · Building structures intended for erosion prevention actually serve to exacerbate erosion conditions on adjacent or nearby properties, and · Wakes from boats producing erosive action on the shoreline (NYS DEC, 2007) Engineered structures can halt, retard, mitigate or accelerate shoreline erosion. Erosion and accretion of beaches, inlet opening and closing, alterations in bay environments, bluff slumping, dune loss, wetland loss and other changes to coastal environments have been occurring naturally on a routine basis since the glacial retreat. These events, whether occurring incrementally or in a single storm event, are part of a natural system. The placement of hard structures (e.g., groins, jetties, bulkheads, revetments, seawalls) or soft structures (e.g., beach nourishment, vegetation, beach scraping, dune building) on dynamic landforms D~A ~000 Hazaid Mitigaiion Plan ~ §Uffoik ~ouniyl i%~ Yoi~ DRAFT- September 2007 5.4,5-5 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION and in flood plains adjacent to coastal waters may not always comply with the dynamic nature of tile landforln to produce the desired results of erosion control. Through human intervention of these natural coastal processes, coastal erosion in some areas has been mitigated while in other areas it has accelerated (Cuomo, 1994). On the South Shore, especially~ the east-to-west flow of sand has been significantly or partially disrupted by the 69 major groins and jetties built to protect significantly eroded stretches of beach and keep six inlets navigable for boats. Shoreline erosion problems are severe immediately west of some of these inlets (e.g., Shinnecock Inlet) because the natural sand transport process has been interrupted by inlet stabilization (Cuomo, 1994). The most dramatic example where groins have contributed to downdrifi erosion is in Westhampton, where construction during the 1960s of 11 rocky groins projecting into the ocean had led to devastating erosion along Dune Road, just west of the sand-grabbing groins. Mr. Jay Tanski of the New York Sea Grant Institute at the State University at Stony Brook, indicated that "The interruption of the natural sand flow has caused very severe problems and the most spectacular erosion that we see.'" It is noted that the subject groin field was intended to extend all the way to Moriches Inlet to avoid this problem, but lack of funding precluded the remaining groins to be built, .leaving the area east of Moriches Inlet very vulnerable to erosion. The USACE, which built many of those groins and jetties, now favors "soft'" erosion-control methods, where applicable, such as building up vulnerable beaches and protective dunes. Pumping sand across inlets to avoid interruption of the natural sand flow has been used at Shinnecock and Moriches Inlets. Reduction in Sand/Sediment Supply Beaches and barrier landforms are created by sediment (predominantly sand) that is constantly in motiofi as a result of coastal processes. General landform conditions are dependent on the amount of sediment entering or leaving an area. Sediment supply is critical in determining whether a beach or barrier landform erodes, remains stable, or accretes. A large portion of SC's coastline consists of barrier beaches and islands, which are perhaps the most dynamic coastal land masses along the open ocean coast. According to the Committee on Coastal Erosion Zone Management, Water Science and Technology Board, Marine Board, and National Research Council, barrier beaches can extend continuously for 10 to 100 miles, interrupted only by tidal inlets. Physically separated barrier islands often are linked by the longshore sediment transport system, so that an engineering action taken in any one beach area can have major impacts on adjacent downdrifi beaches. For example, the south shore of Long Island is considered a littoral system, where the eroding headlands and mainland beaches of Montauk Point to the east and beaches along the eastern regions of SC supply sand that moves westward along the barrier beach chain (Southampton/Westhampton beaches, Fire Island, Jones Beach and the Rockaways). Barrier islands are typically low lying, flood prone and underlain by easily erodible, unconsolidated sediments (Aquilino, 1990). The volume of sediment supply to any beach or barrier landform depends upon sediment source (for example, glacial bluffs) and the transport pathway from source to landform (Cuomo, 1994). Reduction in the sand/sediment supply, either from landward or seaward (primarily reef) sources, can have a myriad of causes. Obvious causes such as beach sand mining and structures that prevent natural access to beach deposits remove sediment from the active littoral system. An example of this includes the Port Jefferson harbor where large amounts of sand and gravel were excavated for use as fill and cement binder for construction (USEPA, 2003) Alongshore sediment transport occurs in the nearshore and surf zone. Pathways can be blocked by natural and man-made structures built perpendicular to the shore. Interference with sediment transport DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.5-6 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION can result in excess sediment, (beach accretion), on the side from which sediment is coming (updrifi), and sediment starvation, (increased erosion), along the downdrift side of the structure. Examples of this can be seen along the eastera and western shorelines adjacent to the many inlets along the south shore of SC as seen at the Shinnecock Inlet in Figure 5-107. Fi 31e of Sand Transport Source: (AeroGraphic Corp, 1988) Rising Sea Levels Rising sea levels result in the landward migration of the shoreline (OCDA, Date Unknown). Along much of New York's coast, sea level already is rising 10 inches per century, and can rise up to another 22 inches (as a potential on the higher end of the range of possible sea level rise predictions) by 2100 Sea levels rise due to a variety of causes, which occur over different temporal intervals and vary in magnitude. Such causes include, but are not limited to, changes in sea floor spreading rates, changes in areas of ocean and land, changes in direction of movement of plates, thermal effects, and climate effects (i.e., global warming) (Cuomo, 1994). Sea level rise can lead to the flooding of low-lying coastal areas; extension of flood zone areas inland; loss and/or displacement of coastal wetlands and other types of coastal habitats; accelerated erosion of beaches; dune line recession; saltwater contamination of drinking water; decreased longevity of low-lying roads, causeways, and bridges; displacement of coastal habitats; and decreases in the ability of the natural barrier, bay, and wetland systems to maintain themselves, especially in light of present human shoreline DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT- September 2007 5.4.5-7 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION alterations. According to th~ Governor's Coastal Erosion Task Force Final Report, hardened shorelines prevent the natural migration and response of wetlands and barriers to climatic forces and as a consequence, cause the destruction of these natural protective features and a loss of the benefits they provide for wildlife habitats, storm protection and recreation (Cuomo, 1994). However, soft solutions such as beach renourishment, ]nay in certain circumstances prolong the life of these existing features, where desirable. In addition, sea level rise could increase the vulnerability of coastal areas to storms and associated flooding. NYS has one of the most urbanized coastlines in the United States. Over 20 million people use NYS beaches and coastal regions for recreation each year. NYS has been successful at preventing major permanent losses of its beaches and urban coastline, but sites such as Long Island continue to suffer from chronic beach erosion in isolated sections of the coastline. Long Island's south shore, comprised of barrier islands, barrier spits, ponds, and sand beaches, could suffer extensive damage from significantly higher than conservatively predicted sea level rise. According to a projection by the National Environmental Trust (NET), a Washington, DC-based advocacy group, much of Long Island's extensive barrier beach, would be submerged if sea levels rise by three feet. Figure 5-108 shows the current conditions of Southampton, NY and Figure 5-109 shows the potential change in land if the sea rises one meter (WhyFiles, 1999). Figure 5-110 identifies how the shorelines of the Town of Islip might change over the next 50 to 100 years in response to potential changes in the sea level increases.

These mapping efforts are a part of an ongoing project by Jay Tanski, who is working on the use of computer-based tools of a Geographic Information System to provide decision makers with information about coastal conditions and processes at a scale they can use.

EROSION extensive damage to publicly and privately owned property and to natural resources as well as endangering human lives. When this erosion occurs, individuals and private businesses are prone to suffer significant economic losses, as does the state's economy. Location and Extent Long Island is particularly vulnerable to erosion because of fine-groined sand and its location facing the ocean in various degrees of orientation opposing the dominant wind and water currents moving up the Atlantic Coast). SC is surrounded by the Long Island Sound to the north and the Atlantic Ocean to the south; therefore, coastal erosion is an ongoing process along the northern and southern shoreline communities and natural ecosystems (including barrier islands, bays, inlets, beaches and tidal wetlands). Long Island consists of over 1,180 miles of coastline, with SC consisting of over 980 miles of coastline, some of which have experienced coastal erosion at one time or another, primarily exacerbated by major coastal storms that have directly or indirectly impacted the area. Although there are many contributing factors to coastal erosion, the historical occurrence of coastal storms has been the major contributing factor, permanently changing the landscape of SC's shorelines, with the 'creation of inlets (Shinnecock and Moriches Inlets) as an overall minor to moderate contributor to coastal erosion. According to a 20-year study conducted on a stretch of beach on the east end of Long Island by SUNY Stony Brook Marine Sciences Division, the average coastal erosion rate along the south and north shore of Long Island, NY has been calculated as 1 to 2 feet/year although isolated areas suffer more significant erosion up to about 5 feet/year. This erosion rate is relatively small compared to most of the rest of the east coast (Feitner, 2007; Surfrider Foundation, 2007). According to Gil Hanse of the Town of Babylon, this study is not typical of Jones lsland (Gilgo Beach), where erosion losses may be 5 feet per minor coastal event, including Nor'Easters. The actual annual erosion rate for Jones Island is n6t consistent due · to the extreme erosion experienced during storm events. The USGS coastal erosion maps presented later in this section support this. Along the South Shore of SC susceptibility to coastal erosion is influenced by the continuous transport of sand along the shoreline from the east to the west. This sediment transport is affected overall by natural processes to a major degree and man-made structures to a minor degree. The North Shore does not appear to be as vulnerable to coastal erosion from the natural drift of sand along the shoreline. With calmer seas, lower storm characteristics and the segmented shore's many harbors serve to keep more sand in place, the sand transport rate anywhere along the northern shoreline is never greater than 100,000 cubic yards per year (Fagin, 2006) compared with as much as 300,000 to about 500,000 cubic yards per year along the southern shoreline. However, evidence has shown that the North Shore has lost an average of 1 to 2 feet of shoreline each year, which is caused by storm activity to a major degree rising sea levels and inept erosion-control efforts by humans to a minor, localized degree. Please reference that the source for this rate is a 20-year study conducted by SUNY Stony Brook Marine Sciences Division. This study occurred on a stretch of beach on the East End of Long Island. This study is not typical of Jones Island (Gilgo Beach), where we may suffer erosion losses of 5 feet per minor coastal event, including nor'easters. Refer to documentation in USACE projects from 1987 to present. The actual annual erosion rate for Jones Island is not consistent due to the extreme erosion experienced during storm events According to Dan Fagin of Newsday, the relentless surf has not only chewed up cliffs and thinned beaches, it has also drastically reshaped Long Island over the centuries. The missing ridge south of Montauk is perhaps the most dramatic example of erosion's power on Long Island. It is probably part of the terminal moraine, the line that marks the place where, 22,000 years ago, a glacier finally stopped expanding southward. No section of Long Island's 1,180-mile coastline is immune from erosion's effects, D~ ~000 HaZard Miiigaiion Pia~ ~ Suffolk county, New York' DRAFT- September 2007 5.4.5-10 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION but the Montauk peninsula has been hardest hit because it is unprotected by barrier islands and ties squarely on the historic pathway of numerous nor'easters and hurricanes. Over thousands of years, the area has been narrowed so severely that Long Island's axis has shifted like a weathervane from east-west to northeast-southwest. Massive amounts of sand have been taken from the vanished moraine and from the cliffs at Montauk and pushed west, blown by the prevailing northeast winds (Fagin, 2006). Due to the ongoing coastal erosion problems along the NYS Coastline, the State Legislature passed the Coastal Erosion Hazard Areas {CEHA) Act (Article 34 of the Environmental Conservation Law (ECL)), establishing the State's coastal policy in August 1981. Under this act: · Areas prone to coastal erosion are identified. · Activities in areas subject to coastal erosion are undertaken in such a way that damage to property is minimized, increases in coastal erosion are prevented, and natural protective features are protected. Public actions likely to encourage new development in CEHA should not be undertaken unless the areas are protected by structural or other erosion control projects which could prevent erosion damage during the life of the proposed action. · Erosion control projects are publicly financed only where needed to protect human life for existing or new development, which absolutely requires a location within a given hazard area. · Public and private erosion control projects should minimize damage to other human-made property, natural protective features, and other natural resources. Pursuant to Article 34, the NYS DEC has identified and mapped CEHA experiencing greater than one foot/year of long-term, average erosion-related recession and areas which function as natural erosion protective features along the state's marine and Great Lake coasts. The CEHA maps show the boundaries of such areas, annual rates of shoreline recession, and the boundaries of natural protective features (O'Neill, 1989), As a part of this Act, NYS DEC has developed minimum standards and criteria, 6 NYCRR Part 505 - Coastal Erosion Management, for the statewide regulation of development and other activities within CEHA. Part 505 defines when the Department will administer a regulatory program within identified CEHA and establishes standards for the issuance of coastal erosion management permits by the Depamnent. Procedural requirements are also established for local governments that wish to implement a local program, although local implementation is not required until after the Department has filed CEHA maps for a municipality (NYS DEC, 1988). Part 505 establishes two categories of CEHA: (l) Structural ttazard Areas and (2) Natural Protective Features.' Strttctural Hazard Areas: areas where the long term average annual rate of recession is at least I foot per year and which are likely to be subject to erosion within a 40-year period. The inland boundary of a structural hazard area is a line parallel to the landward edge of the fronting natural protective feature at a distance of 40 times the long-term average annual recession rate at that site, measured perpendicular to that landward edge. Natural Protective Feature Area (NPFA)s: areas such as beaches, dunes, bluffs, nearshore areas and wetlands, the alterations of which might reduce or destroy the protection against coastal erosion that the feature afford to other lands, or lower the reserves of sand or other natural materials available to replenish storm losses through natural processes (O'Neill, 1989). Both types of areas are depicted on CEHA maps, which depict the landward limit of the Surface Hazard Areas and Natural Protective Features and indicate the recession rate in feet per year where applicable. DMA 2000 HaZard Mitigation Plan ' Suffolk couniy, New York DRAFT- September 2007 5.415:ii SECTION 5,4.5: RISK ASSESSMENT - COASTAL EROSION The NYS DEC commissioner is tasked to review the boundaries of these hazard areas every 10 years and after major coastal storms and revise the maps if the CEHA boundary changed by 25 feet or more (NYSDEC Article 34, Chapter 841). According to Mr. Jay Tanski, Outreach Specialist for Coastal Hazards (SUNY Stonybrook) with the NY Sea Grant, such updates have not been implemented in recent years. Therefore, the 1988 maps are still the most recent regulatory delineations of the CEHA. The digitized CEHA line and 1,000-foot buffer zone for SC was provided regional and local erosion rates by Mr. Robert McDonough of the NYS DEC, Division of Water, Coastal Erosion Management Unit in June 2007. Figures 5-111 through 5-117 illustrate the digitized line and the average rate at which the eroding shoreline moves landward, expressed in feet per year, for SC and participating jurisdictions. Although NYS DEC's digitized CEHA line included a rate of recession attribute (as show in the figure legends), it appears the rate for the SC coastline is undefined (illustrated as a blue line in Figures 5-111 through 5-117). There is no figure for the Village of Bellport because there is no mapped CEHA line along its coastline. CEHA jurisdiction extends 1,000 feet seaward of the mean Iow water level or to a depth of 15 feet, whichever is greater. The 1,000 foot buffer on the seaward side of the CEHA or NPFA landward,limit line has been placed as a reminder of the seaward limit of the nearshore area which is regulated as a Natural Protective Feature. As explained by Mr. McDonough, the CEHA maps filed with the municipality are the official documents containing the legally defined NPFA and SHA boundary lines and should be referred to when considering areas subject to the coastal erosion hazard.

RISK ASSESSMENT - COASTAL EROSION According to the Long Island Regional Planning Board (LIRPB), NYS has one of the most densely developed and heavily used coastlines in the U.S. The growing population in the New York City/Long Island metropolitan area increases the demand for recreational, residential, and commercial development. In 1990, SC ranked as one of the top ten counties in the country in terms of residential construction growth. Area beaches are a prime recreational resource attracting more than 20 million visitors annually (LIRPB, 1989) and serve as the foundation of a muhibillion-dollar regional tourism industry. Highly desirable for a variety of uses, these coastal areas are also extremely dynamic and subject to significant changes due to both natural processes associated with wind, waves and tides, and human activities. The dynamic nature of Long Island's south shore coupled with a large population's desire to live, work, and play along this coast present unique challenges for decision makers, residents and coastal resource users who are concerned with balancing use, conservation, and development along this urban and suburban coastal area. To achieve this balance, these stakeholders need timely, factual, information that allows them to better understand the natural and human-influenced processes shaping and impacting the coast and the relative role of each. This increased understanding will assist stakeholders to anticipate shoreline changes and impacts and to evaluate regional and local mitigation strategies for dealing with coastal erosion. The Atlantic Coast of New York Monitoring Program (ACNYMP), a cooperative effort of the NYS Department of State (DOS), USACE New York District and New York Sea Grant was initiated to help meet these informational needs (Tanski-Pendergrass, Date Unknown). Since 1995, the ACNYMP has been collecting information and data on beach changes and coastal processes for the 135-mile (210 kilometers) stretch of shoreline between Coney Island and Montauk Point. The goal of the ACNYMP is to provide coastal managers, regulators, government officials and the public with information that will allow them to make better decisions regarding coastal erosion hazard management and resource use. Data collected under the program includes semi-annual beach profile surveys taken at over 348 locations along the shoreline and semi-annual aerial photograi~hs of the entire · coast. Historical data and information from other coastal projects (including historical shorelines, topography, locations of structures, flood zone delineations, etc.) are also being compiled as part of this effort. This data was compiled in the ACNYMP Data Viewer which contains a range of information types, including: beach profile surveys, seasonal aerial photographs, historical shorelines, and cultural and physical data. Additionally, a general CEHA line was established. This data is continually being updated as new information becomes available. The USEPA identifies that SC consists of over 155 beaches and parks; however, some are more susceptible to coastal erosion then others (USEPA, 2004). According to ACNYMP, particular south shore beaches, parks, and residential and natural communities located within the southern CEHA zone that are moderately or highly susceptible to coastal erosion include the following (from west to east): Jones Island Reach: · West Gilgo Beach Gilgo Beach Gilgo State Park Cedar Beach Oak Beach Captree State Park / Island Fire Island Reach: Democrat Point Great South Beach Robert Moses State Park Kismet Saltaire Fair Harbor Lonelyville Atlantique Robbins Rest Dunewood Ocean Beach Ocean Bay Park Point o'Woods Cherry Grove Fire Island Beach/Fire Island Pines Fire Island National Seashore D~A ~DO0 Haz~id Mitigation plan ~ §~ffoik County, New York' DRAFT- September 2007 5.4.5-20 SECTION 5,4.5: RISK ASSESSMENT - COASTAL EROSION Davis Park Bayberry Dunes Westhampton Reach: Cupsoque Beach Westhampton Dunes Potunk Point Westhampton Beach Ponds Reach: Southampton Beach Watermill Beach Mecox Beach Sagoponack Inlet Wainscott Beach Montauk Reach (South Fork or "The Hamptons"): East Hampton Beach Atlantic Double Dunes Amagansett Beach Napeague Beach Moriches Inlet Slnith Point County Park Hampton Beach Quogue Beach Tiana Beach Shinnecock lnlet Montauk Beach Montauk Point Montauk Park ACNYMP only identifies those locations within the CEHA line along the South Shore, therefore, this soarce does not identify the CEHA line along the North Shore or East End of the Island.

The barrier island is also home to private residences, natural and cultural resources (i.e., tidal wetlands, beaches and parks) and wildlife; prevent flooding on the mainland; and serve as a support structure for Ocean Parkway (a NYS commuter highway) and the SC Sewer District 3 outfall pipe. According to the Town of Babylon, Jones Island, the main barrier island within the Town, has experienced significan~ erosion in the past and continues to be extremely vulnerable to coastal erosion, increasing the mainland's exposure and vulnerability to more severe coastal flooding.

One of the main goals of this massive project was the construction of Ocean Parkway, a commuter highway now under the jurisdiction of NYSDOT. Much of Ocean Parkway was completed by 1929, and the roadway was extended to Babylon during the mid-1930s, with accompanying structural engineering and extension of Jones Island (Feitner, 2007). Oak Beach has had a long history of inlet openings and has experienced significant erosion during the years between 1930 and 1960. In 1834, an inlet existed between Captree Island and Oak lsland. The inlet later filled in; however, breaches and overwash continued to occur in this area. A 1959 sand dike, or "sore thumb", was built by USACE to reduce the scour of Oak Beach. However, storms have caused substantial erosion to the tip of "sore thumb." Littoral drift for Oak Beach is now predominantly to the east (McCormick et. al., 1984; Cashin Associates, 1994). Also within the Town of Babylon, Fire Island Inlet is an inlet located between Jones Island and the western end of Fire Island (south of the "sore thumb" and Oak Beach). The accretion of sand by longshore drift has extended the western end of Fire Island a distance of more than five miles (at a rate of about 50 meters per year) since 1825. In 1941, a 1,525 meter jetty was constructed by the Federal Government on the eastern shoulder of the western end of Fire lsland, known as Democrat Point, and modified in 1948 to increase the inlet width and depth (Figure 5-119).

Figure 5-119. Aerial Photograph of Fire Island Inlet Source: USGS, 2003 The following is an excerpt from "The Coastal Geomorphology of Fire Island: A Portrait of Continuity and Change" describing the result of the Federal project in 1948: 'The shoaling that occurred resulted in a tendency for the inlet channel to relocate to the north and . increasing erosion to Oak Beach and Gilgo Beach, located to the west of the inlet. These conditions led to the modification of the Federal project at Fire Island Inlet to include shore stabilization of the area extending from Fire Island Inlet to Jones Inlet. The area within the inlet to produce a southward shift of the navigation channel and to provide fill material for the feeder beach located about 3.2 kilometers west of Democrat Point/Oak Beach (the area was dredged to a mean low water depth of 5.5 meters for a length of 2,100 meters with a width varying from 180 to 365 meters); and 3) construction of an 800-meter sand dike across the inlet gorge extending southeast from Oak Beach. This attempt to stabilize the navigation channel and to reduce erosion on the north and west shores of the inlet, was completed in 1959. Thc sand dike was successful in maintaining channel position and minimizing erosion on the northwestern shore. However, the inlet continues to experience shoaling, in high enough amounts that require frequent dredging. As a result, modification of the Federal project to incorporate sand bypassing at Fire Island inlet was authorized in 1971. Since 1971. the maintenance of Fire Island Inlet has consisted of periodic dredging of the navigation channel, sporadic dredging of the littoral reservoir immediately adjacent to the jetty, land reclamation, and feeder beach nourishment. Dredging of the inlet has been performed almost annually since 1954, totaling nearly 16 million cubic meters from 1954 to 1994 or about 400,000 m3/year. The present cost of dredging at Fire Island Inlet is about $6 million per year. Most of the dredged materials have been. placed x~est of the inlet between Fire Island and Jones Inlet (the sand was bypassed to the down-drift si&IF Numerous structural and non-structural measures have been taken, and millions of dollars spent to create and preserve Jones Island in the Town of Babylon.

According to the "Environmental Study of the Barrier and Bay Island Communities" for the Town of Babylon, sections of Gilgo and West Gilgo Beaches, that adjoin the southward extensions of the Great Bay, are likely sites of future inlet formation. These segments are vulnerable to coastal erosion due to their narrow width and the continued deterioration of the dunes (Cashin Associates, 1994). Ocean Parkway, located on Jones Island, connects with the Robert Moses Causeway, Wantagh, Meadowbrook and Loop parkways and provides residents and, vehicular access for tourists to the south shore beaches. Commuters also utilize this parkway as an alternate route to more congested State parkways such as Southern State Parkway. Local and state agencies have spent millions of dollars on emergency measures to ensure the integrity of Ocean Parkway (LIRPB, 1989). Figure 5-118 illustrates Ocean Parkway along Jones Island. The SC Department of Public Works Sewer District 3 maintains a sewer outfall pipe that runs from the main island, traverses Cedar Island and continues 2.5 miles into the Atlantic Ocean. This outfall serves the Towns of Babylon and Islip, and the barrier islands. According to "The Proposed Long Island South Shore Hazard Management Program" by the Long Island Regional Planning Board, it is essential that the continuity of this barrier island [Jones Island] be maintained to prevent its retreat and protect the integrity of these outfall pipes." SCDPW recognizes the outfall pipe's vulnerability to storms and coastal erosion. The cover for the pipe was approximately 17 feet at the barrier beach shoreline and typical cover in the ocean was 10 feet. However, 1981 and later assessments indicated that storms reduced cover to 8 feet at the shoreline. Additionally, anode beds and an electrode cable installed five feet below the ocean floor; were exposed by 1990. In 1992, an estimated $3.5 million project was implemented to install 700-feet of sheet piling on the pipe with a rehabilitated cathodic protection system at the shoreline. SC DPW is currently having the life expectancy of the outfall system evaluated. Preliminary assessments indicate that '~he system does not have the 100-year life as projected in 1980 (Wright, 2007). Fire Island: Since Moriches Inlet first opened in 1931, Fire Island Barrier Beach has experienced increased beach and dune erosion, which is likely due primarily to storm activity exacerbated to some extent by both offshore bathymetry and a sharper angled orientation that allows for increased erosive forces, and to a lesser extent due to sand trapping at Moriches Inlet. Over the past 25 years, an estimated sand loss of 8 to 10 million cubic yards has occurred along the 32 miles of Fire Island. That volume of sand represents a loss of 100 feet of beach and a depth of 12-16 feet along the entire Fire Island beach zone (Mandia, 1992). The west end of Fire Island, Fire Island Inlet, is routinely dredged so that upwards of 500,000 cubic yards of sand spoil is placed in an average year on a down drifl beach such as Gilgo. Three communities on Fire Island dredged some 400,000 cubic yards in 1959 following severe storms during 1957. Apparently, the first stabilization of Moriches Inlet was beginning to affect the sand flow to Fire lsland along with the significant erosional impacts of the hurricanes and storms in the mid 1950's and early 1960's, because approximately 1,650,000 cubic yards of sand were placed on Fire Island in the 1960 to 1964 time period. About 60% of this sand was placed near the Moriches inlet in 1963 after the disastrous northeaster storm of March 1962. By this time, it was evident that there could be trouble ahead for the area around the inlet. Another 715,000 cubic yards was authorized under an emergency program for Fire Island, called Operation Five High (named after the 1962 storm that held for five high tides). Small quantities of sand were placed in the spots with the most severe erosion from Kismet east to Bellport Beach (about 20 miles). These additions of sand to the littoral system likely mitigated the initial impact of the sand trapping caused by Moriches Inlet and storm activity over the same period. The next five year period, 1964 to 1969, showed about the same amount of sand placed in the littoral drift on Fire Island (nearly 1.8 million cubic yards in that 5 year period) with more than half of it placed just to the west of Moriches DU~ ~ooo ~-~aid Mitigation Plan - Suffolk County, New York DRAFT- September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION Inlet in the area which had begun to erode. In 1970, the nourishment program was essentially stopped. (Spencer & Terehunian, Date Unknown). Mattituck Creek/Inlet (Town of Southold): An April 2006 USACE Evaluation of Downdrift Shore Erosion, Mattituck Inlet, New York: Section I11 Study, was conducted to investigate shore erosion downdrift of Mattituck Inlet, NY. This evaluated the degree to which jetties stabilizing the Federal navigation project and channel operation and maintenance activities are responsible for erosion downdrift of the Mattituck Inlet. The downdrift barrier beach at Matticuck Creek has narrowed and, in the past, was subject to breaching. Two rabble-mound jetties were constructed at Mattituck Inlet in 1906 to stabilize a Federal navigation channel and support local commercial and recreational use. Littoral transport of sediments/sand was disrupted as a response to construction of the jetties and maintenance of the channel. Sediment impoundment updrift of the inlet deprived downdrift beaches of material, causing increased rates of shoreline recession east of the inlet. The 2006 Study indicated that regional shoreline change rates from Mt. Sinai to Horton Point were determined from three surveys of shorelines performed between 1885 and 2001 (spanning 116 year. s). Long-term regional background shoreline recession rates were calculated to determine the response of adjacent shorelines to the Federal navigation project at Mattituck Inlet. These rates were established to better understand coastal processes and to provide comparative background erosion rates to evaluate shoreline change adjacent to Mattituck Inlet. A 1969 USACE study for the northern shore of SC, for the years 1836-1838, 1885-1886 and 1965, indicated erosion as the dominant process (approximately 2 feet/year) with localized areas of accretion. A 1971 USACE study indicated that severe recession was noted in the Mattituck Hills area (approximately I mile updrift of the Mattituck Inlet) with rates reaching 3.5 feet/year. The entire shoreline east of Mt. Sinai Harbor to Orient Point was classified as a "critical" erosion area. Areas of shoreline recession were reclassified following a review of the 1971 Study by Bartholomew and McGuiness in 1972, and it was the north shore of SC was classified as "areas where continued critical erosion is likely to endanger property, scarce wildlife habitats, or landmarks of historical or natural significance within 5 years." A 1975 Long Island Sound Regional Study, completed by the New England River Basins Commission, interpreted data compiled from previous studies to identify areas of high erosion damage and develop long-term mitigation plans. Coastal losses in the study area were estimated at 15 acres/year, with annual damages in response to shore erosion estimated at 1.3 million dollars (1970 USD). Annual damages for 1990 and 2000 were estimated at $2 and $4 million, respectively. Fields et al. (1999) prepared the most comprehensive study of regional and localized shoreline change available within the Town of Southold at that time, encompassing 217 miles of coastline from Mt. Sinai Harbor to Orient Point. This study indicated that the regional shoreline from Mt. Sinai Harbor to Horton Point demonstrated that the eastern north shore of Long Island has a long-term trend of shoreline recession at a rate of approximately 1 foot/year in the last 116 years. The shoreline directly downdrift of the Matlituck Inlet had the highest value of shoreline recession for the 1885 to 1965 interval. This recession area downdrffi of the inlet is also apparent between 1965 and 2001. During this study, on a localized scale, it was determined that downdrift of the inlet, two zones of shoreline recession were apparent, extending for a total distance of approximately 9,600 ft east. The first zone, or primary recession area, consists of the 4,000 ft of shoreline directly to the east of the inlet. Along the next 5,600 ft, the east shoreline recession rates decrease; this area is defined as the secondary recession area (Figure 5-120) (Batten & Kraus 2006).

Between 1933 and 1938, Moriches Inlet widened and deepened as tidal currents deposited sand in large deltas on the ocean and bay sides of the inlet. The Great Hurricane of 1938 further widened the Inlet to over 4,000 feet. It also created 12 more inlets to the east, including Shinnecock Inlet. Once Shinnecock Inlet opened, Moriches began to shoal up as there was less tidal pressure to scour the channels twice a day. Between 1938 and 1980, a series of dredging projects took place within Moriches Inlet, which created a series of channel shoalings and water quality changes that created numerous shoreline changes to the Inlet and Bay. These changes to the Inlet and Bay system provided a significant sand trap for the littoral transport from east of Moriches lnlet.. The USACE estimates that Moriches Inlet has annually trapped 178,000 cubic yards of sand in the ebb and flood tidal shoals since 1953. However, sand bypassing to mitigate the sand trapping at the Inlet has occurred since the early 1990's. Shinnecock Bay (Shinnecock Inlet): Shinnecock Inlet, when opened in 1938 by the Long Island Express, immediately began trapping sand. The amount of sand trapped annually inside Shinnecock Bay was calculated to be approximately 60,000 cubic yards per year between the years 1955 and 1969. The USACE confirmed that Shinnecock Inlet is trapping between 55,000 and 120,000 cubic yards of sand annually and the shoreline to the west of the lnlet has been eroding as a result of the sand trapping. According to a study in 1961, the natural rate of beach erosion (due to the littoral transport) of the area west of the future Shinnecock Inlet location was 1.2 feet per year. After the inlet was created by the hurricane and stabilized by jetties and dredging in the 1950's, the rate of erosion to the west of the inlet increased to 8.2 feet per year. Other studies published by the USACE both confirm that Shinnecock Inlet is trapping between 55,000 and 120,000 cubic yards of sand annually and that the shoreline west of the Inlet has been eroding as a result of the sand trapping. Since the late 1990's sand dredged from the Inlet has been bypassed downdrift to mitigate against the sand trapping at the Inlet. This met with little success to reduce the erosion just west of the Inlet until the last several years when a large beach renourishment operation was accomplished from a nearby offshore borrow area (with better sand quality than dredged from the Inlet) that has reduced erosion there significantly, at least for the time being. Westhampton Groin Field: The Westhampton Groin Fields (a series of 15 stone structures protruding from the shoreline and encompassing a 3.2 mile stretch of the South Shore of Westhampton) were constructed in the mid-1960s and the eafly-1970s to stop the erosion of sand induced mainly from the impacts of significant hu~cane and storm activity in the mid 1950's and early 1960's. The result of these structures was that a massive new sand trap had been constructed. The east side of the groin field experienced massive beach widening and the downdrift (west) side experienced major new erosion DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.5-27 DRAFT- September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION problems. According to the 'Long Island Regional Planning Board in 1989, downdrift from these groins averaged of 55,000 cubic yards of sand per year (net loss). The known total volume trapped by 1991 was 2.4 million cubic yards (Mandia, 1992). The groins formed a littoral barrier. The barrier island west of the groin field was weakened and subsequent inlet broaching occurred. Increased erosion just to the east of Moriches Inlet and some bayside narrowing resulted in a breach during January 1980 in the same location as the 1933 inlet breach. The new inlet widened to a half mile by summer and was subsequently filled at a cost of $12 million. Unfortunately, the factors that caused the breach, blockage of sand at the Westhampton groin field were not addressed at the time. By 1992, the three mile stretch of beach from the last groin to Moriches Inlet had degraded so badly that the island overwashed during spring tides. On December 11, 1992, a severe Northeast storm ripped two breaches through the barrier island. By the time action was taken to close the breaches (started in August, 1993), one breach had widened from 200 feet to over 3,600 feet; the breach cost $8.8 million to close (Spencer & Terchunian, Date Unknown). However, in the late 1990's a beach restoration project was constructed to the west of the groin field which continues to be renourished, providing a relatively stable stretch of shoreline compared with the previous 30+ years. Asharoken Beach, Village of Asharoken (Town of Huntington): Asharoken Beach is a narrow section of land in the Town of Huntington on the north shore of Long Island, connecting Eaton's Neck and the Village of Asharoken with the Village of Northport. The length of Asharoken Beach is approximately 2.5 miles, while its width varies from 100 feet at the northwestern section near Eaton's Neck to 1,000 feet at the southeastern limit near the Long lsland Lighting Company (LILCO) (Keyspan) facility. The roadway along Asharoken Beach, Asharoken Avenue, provides the only vehicular access to Eaton's neck. Recent coastal storms have accelerated shoreline erosion and inundated highly developed areas. Asharoken has incurred major losses due to coastal erosion and flooding (Gmbb, Date Unknown). In addition, according to the USEPA, the loss of beachfront in some areas surrounding Asharoken now leaves the beaches of Asharoken increasingly vulnerable to severe coastal damages even from moderate storms (Ortiz, 2002). Coastal storms are not the only cause of erosion of the Asharoken Beach. A Sediment Transport Analysis (North Shore of Long Island, New York-Combined Erosion Control and Storm Damage Protection Feasibility Study) was completed in August 2004 by USACE, which includes information regarding the shoreline changes of the Asharoken Beach. According to this study, the Metropolitan Sand and Gravel Co. (MSG) constructed two jetties between 1931 and 1932, into Long Island Sound at the western comer ofit~ property (east of the Village border). Shortly after the construction of the jetties, additional projects took place including the dredging ora lagoon, known as Northport Basin, and an inlet channel. In 1935, MSG requested and received a 3-year extension for the use and maintenance of the facility until March 1968 when LILCO requested a change in the permit to construct a power plant adjacent to the Northport Basin. As a part of LILCO's plant construction, the existing jetties were rehabilitated into permanent quarrystone and concrete riprap jetties. Also, a watercooling pond was constructed to the east of the power plant with cooling water effluent discharging directly into the Sound via a weir structure of the beach (Figure 5-121 ). Since the construction of the jetties and navigation channel, the shoreline east of the Northport Basin has accreted while the shoreline west of the jetties recessed from its natural position. Approximately 6,000 feet of shoreline west of the jetties has experienced increased beach erosion as a combined effect of disrupted upstream sediment supply and storm erosion activities. Construction of groins and seawalls along the upstream Crab Meadow shoreline in the 1950s and 1960s further reduced the natural sediment source. To counter the erosion, various structures (timber bulkheads, interlocking groins and a concrete and stone groin) were constructed by homeowners and the NYS Department of Public Works, along the eroded stretch of the beach to avoid additional erosion. In the 1960s, approximately 840,000 cubic yards of sand nourishment was placed on the beach from a borrow area located approximately 1,000 feet directly offshore. Since the construction of the power plant facility, D~ 2000 Ha~-~id ~iii~ati~n Pi~n -suffoi~ ~o~nty, New YOr~ DRAFT- September 2007 5.4.5-28 sEcTIoN 5.4.5: RISK ASSESSMENT - COASTAL EROSION LILCO (now known as Keyspan) continuously bypassed shoaling material dredged from the boat channel and basin and deposited it on the beach west of the jetties. Keyspan indicated that the average bypass rate between 1962 and 2001 has been approximately 10,000 cubic yards/year. Even after receiving p~riodical bypassing at an average rate of 10,000 cubic yards/year between the 1962 and 2001 and a one-time beachfill of 840,000 cubic yards in the middle portion of Asharoken Beach, the western shoreline experienced continued beach erosion on the order of 2 feet/year. A 2004 USACE study presents a description of sediment transport patterns and processes for the shoreline of Asharoken. Through the use ora variety of different models, the study conducted a sediment budget analysis to quantify baseline and existing transport rates, the establishment of historical shoreline changes, simulations of sediment transport pattern vicinity of the Keyspan cooling water outfalls, and an investigation of the extent of jetties influence on the Asharoken shoreline through the simulation of a hypothetical future condition with the Keyspan plant jetties removed. This study revealed the following information: Overall shoreline change trends between 1962 and 2001 document a general increase in erosion rates from Asharoken Beach (west of Northport Basin and Keyspan jetty) to Eaton's Neck Point. East of the Keyspan facility, change patterns remained relatively consistent through time. A comparison of beach erosion rates prior to and after jetty construction suggests that, accounting for a beach nourishment and sand bypassing volume of 1,252,200 cubic yards (18,000 c~bic yards/year), the actual erosion rate would increase from the pre-construction rate of 14,000 cubic yards/year to a post-construction rate of 33,000 cubic yards/year, an increase of 19,000 cubic yards/year of erosion due to jetty construction, however this is partially mitigated with approximately 10,000 cubic yards per year of sand bypassing to the downdrift side of the jetties.

Since mapping of the current flood hazards in 1987, storm activity and natural coastal geologic processes have caused further flooding and erosion of Saltaire's Atlantic Ocean and Great South Bay coastlines. Since 1987, over 50 new structures have been added. There are approximately 50 potential buildable parcels within the Village. The Village of Saltaire, located on a barrier island, is entirely situated within mapped flood zones and CEHA. Much of the Village is also situated within mapped freshwater and tidal wetlands. The Village is denorainated a Community Development within the Fire Island National Seashore (Saltaire, Date Unknown). Town of East Hampton: The biggest problem facing East Hampton is beach erosion. The town for the most part has severely restricted development on ocean front property thus limiting the impact. The Montauk Lighthouse, which used to be almost 300 feet from the cliffs is now 56 feet from the cliffs. The most threatened areas are in the hamlet of Montauk, which is the only community in 'the town with its business district next to the ocean as well as with houses near Georgica Pond in East Hampton. The Montauk peninsula has been hardest hit because it is unprotected by barrier islands and lies squarely on the historic pathways of nor'easters and hurricanes. Over thousands of years, the area has been narrowed so severely that Long Island's axis has shifted like a weathervane from east-west to northeast-southwest. Massive amounts of sand have been taken from the vanished moraine and from the cliffs at Montauk and pushed west, blown by the prevailing northeast winds (Fagin, 2007). Town of Shelter Island: Shelter Island is continuously impacted by coastal erosion. Figure 5-122 illustrates the areas along the coast of the island that have been identified as high CEHA (Card, 2007). Figm'e 5-122.

Many houses bordering Moriches Bay lie buried up to their roofs in sand, or have been reduced to rubble. The village survived recent storms, but not without a scare. After Hurricane Felix roared through in August 1995 the combined forces of NYS, SC, and the village~s highway department were needed to supply massive loads of sand and build a berm south of the road. Most of what is now the village was designated a CEHA by the state in 1984. This stretch of barrier beach, which includes the 300-acre Cupsogue Beach County Park before ending at Moriches Inlet, began suffering severe erosion problems after a 22-groin project was started in 1964. Only 15 groins were built and the beach to the west of the last groin, deprived of replenishing sand, began washing away (Shaman, 1996) This ama is no longer subject to significant erosion since the construction of the Westhampton Beach Restoration Project and subsequent renourishment operations beginning in the late 1990's. Previous Occurrences and Losses Although many factors contribute to the natural coastal erosion of SC shorelines; historical hurricanes, tropical storms and nor'easter events have significantly increased coastal erosion processes throughout SC. Because SC is primarily surrounded by coastal waters, most tropical and extratropical events that commonly occur within the area result in significant losses and temporary or permanent changes to the County's shorelines. The Long Island shorelines have historically experienced coastal erosion and related storm damage, most recently from the multiple storms of 1996 and from previous storms including the Christmas Eve 1994 storm, March 1993 Blizzard of the Century, the December 1992 northeaster, Halloween Storm of 1991 ("The Perfect Storm"), Ashe Wednesday Storm of 1962, and the Long Island Express in September 1938. These Storms caused evacuations in several north shore and south shore communities as well as damage from flooding and loss of structures from erosion. Details regarding reported hurricane and nor'easter events that have directly' or indirectly impacted SC are presented in earlier in this section (Section 5.4 o Hurricane and Nor'easter). Although erosion is a common result of most coastal storms that have affected SC, those events that resulted in significant coastal erosion to the northern and southern shorelines are identified in Table 5-35 and discussed further in this section.

One of the most damaging results was the creation of Moriches Inlet. This inlet has created a chain reaction of coastal erosion events to SC's shoreline, particularly along Fire Island Barrier Beaches. September 21-22, 1938 ("The Long Island Express" or "The Great Hurricane of '38"): This Category 3 Hurricane was one of the largest hmricanes to impact the east coast significantly, including the SC area. The storm produced winds that reached 200 miles per hour (mph), generated 5-meter-high breakers, overwashed 1/3 to 1/2 of the island, and created approximately 12 new inlets. It was the worst storm in recorded history for Long Island in terms of fatalities (over 50 people) and property damage (hundreds of homes were completely destroyed or suffered extensive damage), resulting in losses estimated at $6.2 million (in 1938 U.S. Dollars). Perhaps the greatest long-term impact on Long Island from the Great Hurricane of 1938 was the creation of the Shinnecock Inlet and the widening of the Moriches Inlet (over 4,000 feet) to the west (Figure 5-123 and Figure 5-124). To this day, these inlets are changing the landscape of the south shore based on their influence and interruption of the natural littoral sand transport from east to west. Ten additional inlets were created within Long Island, New York as a result of the storm. Over the past 25 years, an estimated sand loss of 8 to 10 million cubic yards has occurred in the 32 miles of Fire Island. That volume of sand represents a loss of 100 feet of beach and a depth of 12 to 16 feet along the entire Fire Island beach zone. Additionally, Southampton suffered DMA 2000 Hazard Mitigation Plan - Suffolk C0untyl New York 5.4.545 DRAFT - September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION heavily along the shore front. From the bathing house to the municipal beach, only two cottages remained standing after the sea swept Dune Road. Among the shattered ruins was St. Andrew's Church of the Dunes. Overall, this 1938 Hurricane has had a significant impact on the coastline that altered natural coastline erosion responses from future storms (Mandia, 1992). 30, 1938 Pre- Shinnecock Inlet Soume: (Off Shore Coastal, Date Unknown) Note: This photograph was taken before the Great New England Hurricane of 21 September 1938 cut Shinnecock Inlet. During the storm, the barrier broached where a channel crosses from the bay to the road. Another identifier of the inlet's location is the left-tight jog in the road, which disappeared when the storm ~vashed away this part of the barrier. This image is part of a mosaic prepared by the Beach Erosion Board, the predecessor organization of the U.S. Army Corps of Engineers' Coastal Engineering Research Center. Fi 1938 Post- Shinnecock Inlet Source: (Off Shore Coastal, Date Unknown) Note: Taken 3 days after Great New England Hurricane, this image shows the new Shinnecock Inlet and many over,gash fans along the adjacent shore. These fans and inlets attest to the tremendous power of this storm, the most devastating hurricane on record to strike the Northeast coast of the United States. All the inlets along this stretch of the coast trended lefi of shore- perpendicular. The overwash fans demonstrate a mechanism by which sand is carried from the open coast into the back bays. This image is part of a mosaic prepared by the Beach Erosion Board, a series of 157 photographs coveting Fire lsland Inlet to Southampton. The photographs were probably taken by the U.S. Army Air Corps, Mitchel Field, Long Island. September 14, 1944 ("Great Atlantic Hurricane'): In the evening of September 14, 1944 the "Great Atlantic Hurricane" storm center crossed the eastern portion of Long Island during a falling tide. Wind gust velocities were reported up to 99 mph with a 5-minute average wind velocity of 82 mph recorded at Block Island. According to the Governor's Coastal Erosion Task Force Final Report Volume II (September 1994), bluffs along the north shore of Long Island were eroded at their base and summer D~A ?000 H'~id Mitigation plan 1 Suffolk County, New York DRAFT- September 2007 5.4. 36 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION homes were "undermined." The U.S. ACE estimated the north shore and the Peconic shorelines suffered $733,000 of total damages from this storm and Westhampton Beach suffered $100,000 of damages (Governor's Coastal Erosion Task Force Final Report, 1994). August 25 - September I, 1954 (Hurricane Carol): Hurricane Carol impacted SC between August 25 and September 1~ 1954, with the worst hit areas being Montauk Point, Riverhead, Westhampton and Amagansett. On September 2, 1954, Long Island, including SC, was declared a disaster area after 275,000 homes were without power, identified by FEMA as Disaster DR~26. Properly loss to both Nassau and Suffolk Counties was estimated at $3 Million from winds of up to 125 mph and waves as high as 14 feet. According to the Governor's Coastal Erosion Task Force Final Report Volume 2, damage to the north shore was in excess of $700,000 (measured in 1954 dollars). Eastern SC bore the full brunt of the hurricane. The average wind speeds at Westhampton Air Force Base were 66 mph with gusts hitting 90 mph (Long lsland Hurricane History, 2007). Montauk Point was closed off for hours by high tide rolling across the neck of Napeague. Water four feet deep and a mile wide poured across Montauk Highway, making Montauk Point a temporary island. The sea broke through the dunes and flooded the main road of the area. In Westhampton, beaches and six homes were destroyed from the high tide, which rolled inshore five or six feet higher then normal. September 9-12, 1960 (Hurricane Donna): Hurricane Donna affected Long Island as a Category 2 Hurricane. Donna holds the record for retaining "major hurricane" status (Category 3 or-greater on the Saffir-Simpson Hurricane Scale) in the Atlantic Basin for the longest period of time on record. Some 10,000 residents of Nassau and Suffolk Counties' South Shore were evacuated before Hurricane Donna hit Long Island. Winds averaged 40 to 50 mph, but reached up to 125 mph off the East End. High tide at Jones Beach swelled to a record 11.7 feet, seven feet above normal. Although with a weaker impact in other areas, this storm caused considerable and widespread damage in New York including coastal erosion. The NYS HMP indicates that damage from this event was estimated at $1.9 million within Long Island. According to the Governor's Coastal Erosion Task Force Final Report Volume 2, the $1.9 million (measured in 1960 dollars) was incurred in areas from Jones Inlet to Montauk Point March 6-8, 1962 (FEMA DR 129) ("Ash Wednesday Storm" - "Five Tide Storm"): According to FEMA, SHELDUS and the 2004 NYS HMP, Long Island communities, such as Fire Island, were decimated by this storm - -with over 100 homes destroyed. The USACE indicates that as a result of this flooding event, a total of 50 washovers occurred and one new inlet at Westhampton Beach (the largest breach over 400 meters wide) was formed. On Fire Island, a total of 47 homes were destroyed and 75 were damaged resulting in property losses estimated in the millions. As a result of this storm, the New York District of the USACE constructed emergency protective works throughout the study area (known as "Operation Five-High" for the five high tides of the storm's duration) (USACE, Date Unknown). On Fire Island, I. 1 million cubic yards of sand was placed along 8.5 miles of shoreline, raising beaches to an elevation of 12 feet above mean low water. Some 9,500 feet of dune and 37,000 feet of eroded beach were quickly restored (Fire Island Association, 2002). According to another source, the storm was responsible for over 75 breaks (washovers) between Fire Island Inlet and Southampton. In the Moriches to Shinnecock Reach, large stretches of Dune Road and 46 houses were destroyed. The west side of Shinnecock Inlet was eroded, and accretion occurred along the east side. President Eisenhower declared the south shore a disaster area eligible for Federal aid. Assistance was provided to the local communities in the removal of debris and in the rebuilding of beaches and dunes. Under authority of Public Law 875, the USACE performed engineering and construction of emergency shore protection and rehabilitation of over 23 miles of beaches and dunes, including the breach of Westhampton Beach. Some 2.21 Million cubic yards of sand was pumped onto beaches, mostly from back bays (Historical Aerial Photos, Date Unknown). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.5-37 DRAFT - September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION This storm is a well documented historic event that caused widespread overwash throughout its path: The Westhampton Beach field of 15 groins was constructed in 1966 and t970 in response to weaknesses of the Long Island, New York, barrier chain (Figure 5-125) created by overwash and breaching during the storms of 1938, 1944, and the Ash Wednesday storm of 1962 (USACE, 2004). Figure 5-125. Overwash on Fire Island Source: (Donnelly, et. al., 2004) Caption: Overwash (white sand fans) on eastem Fire Island, 8 March 1962, in waning stage of March 1962 Ash Wednesday storm (north is at top) September 27, 1985 (Hurricane Gloria): Hurricane Gloria affected Long Island as a Category 2 hurricane, with the worst hit areas within eastern Long Island, including Cutchogue (North Fork), Greenport, Westhampton Beach, Lindenhurst, Riverhead, Northport, Babylon, Brookhaven, East Hampton, Huntington, Islip, Shelter Island, Smithtown, Southampton, Southold, Montauk, Fire Island and Shinnecock Bay. The storm center passed over Fire Island with heavy rain and winds of over 80 mph. $285 million in property damages were sustained and 48 homes were destroyed on Fire Island. Eleven deaths were reported in Long Island (Long Island Hurricane History, 2007). Many beach communities on eastern Long Island reported modest beach erosion with several piers and docks swept away. August 16-29, 1991 (Hurricane Bob): Hurricane Bob impacted SC on August 16-29, 1991, with the worst hit areas being Montauk, Riverhead, Northfork/Southfork, E. Moriches, Sag Harbor to Bayville (North Shore), Port Jefferson, Northport, Centerport, Dering Harbor, Huntington, Greenport, Shinnecock Hills, East Hampton, East Quogue, Southampton, Fire Island, Babylon, Bellport, Medford, Center Moriches and Islip. This event resulted in a FEMA Disaster Declaration (FEMA DR-918), declared on September 16, 1991. According to NYS HMP, this event resulted in approximately $11.7 million in damages to property within Long lsland. This event created significant erosion on Dune Road in Westhampton and along the barrier beaches of the South Shore. DMA 2000 Hazard Mitigation Plan - Suffolk County, New ~ork DRAFT - September 2007 5.4.5-38 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION October 30-31, 1991 ("The Perfect Storm" or "Halloween Storm of 1991"): This storm was an unusual nor'easter which was extratropical, and absorbed one hurricane~ before it ultimately evolved into a small hurricane late in its life cycle. Damages totaled over $10 million throughout NYS and northern New Jersey and it was reported that these two states received the most damage to coastal sections since the Great Atlantic Hurricane of 1944. Homes, boats, roads, beaches and seawalls were destroyed (NCDC, 2004). The worst hit areas in SC included Westhampton, Ocean Beach, Southamptom Montauk, Smith Point, Southold, Fire Island, Babylon, East Hampton, Shelter Island and Orient Beach. This storm caused heavy flooding and severe erosion across Long Island. A tidal surge with waves as high as 15 feet occurred in some places, engulfing the shores and sheering off sweeping stretches of beach from Montauk to Freeport and punching holes in environmentally sensitive barrier beaches. This event appeared to be the worst coastal erosion event at that time and one of the top three erosion events in the area (Figure 5-126). It caused more beach erosion then 'Hurricanes Bob and Gloria. Damage to beaches and bluffs was exacerbated because winds blowing out of the Northeast at up to 62 miles per hour increased water levels as much as 8 feet above normal high tide levels around Long Island~ These water levels did not relent as the normal lunar tides dropped. Damage included the loss of 2.5 miles of dune 20 feet wide and five feet high between Jones Beach and Fire Island Inlet. Restoration of the SC beaches cost considerable money; however, actual U.S. dollar (USD) amounts are unknown. Senator Alfonse D'Amato put the toll of damage at tens of millions of dollars related to houses and barrier beaches (Long Island Hurricane History, 2007). Damage to Townships, Villages and Hamlets in SC include, but are not limited to, the following: · Babylon: Gilgo Beach in Babylon scoured away. A layer of sand five-feet, deep disappeared from Babylon Beaches. · East Hampton: 150 feet of beach was lost at Napeague State Park. On the north side of Montauk, at mouth of Lake Montauk, water washed over Gosman's Dock. A portion of West Lake Drive collapsed and 10 feet of bluff on each side of Montauk Lighthouse was carved out. The flood waters at the Ocean Beach ferry terminal obscured the boundary where the dock ended and land began. Fire Island: 40-foot dunes on Fire Island were leveled. · Islip: Ocean Beach was found underwater, lslip was issued an evacuation order for Fire Island. · Shelter Island: Tides 5 to 8 feet above normal flooded Ram Island causeways on Shelter Island caused Crescent Beach erosion. · Southold: Orient Beach experienced significant damage, causing it to close for an extended period of time. The roadway to the beach was undermined and caved in and the park was completely flooded. The access road to Orient Beach State Park was severed in 10 places. This was one of the hardest hit beaches in Long Island. · Southampton: One of hardest hit areas was Dune Road (Figure 5-127); the barrier beach was breached in two places, dozens of homes were destroyed and thousands of feet of roadway were mined. More than two dozen ocean front homes in Westhampton were smashed into shapeless piles of debris by 10 to 15 foot waves that crashed over Dune Road - more then a mile long section. Many houses were buried in sand and debris. Between 1,500 and 2,000 feet of Dune Road were clearly washed away (Long Island Hurricane History, 2007) DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.5-39 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION Figure 5-126.

DMA 2000 Hazard Mitigation Plan -Suffoik countyl Ne~ York DRAFT - September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION December 11-13 1992: This December 1992 storm inundated hundreds of residential and business properties and caused damages estimated at $12 million. This event resulted in a FEMA Disaster Declaration (FEMA DR-974) for multiple states along the eastern coast (Ortiz~ 2002). As identified in Governor Marlo Cuomo's Coastal Erosion Task Force Final Report (1994), this storm, coupled with other less damaging storms through March 1993. created significant coastal erosion along all shores of SC. The December Nor'easter of 1992 and other 1993 winter storms (for example, March 12 to 14, 1993 Nor'easter), caused widespread physical problems, including extensive beach erosion, dune scarping and overwash, bluff erosion, flooding, significant structural damage and disruption of transportation, utilities and essential services. FEMA reported that direct federal disaster assistance through July 1993, which included disaster funds for the December 1992 storm and the March 1993 storm, totaled $233.6 Million. Such funds include a $5.7 Million contract approved by the USACE to close the breach of Westhampton. This Coastal Erosion Task Force Report idenfifi~s the impacts of various winter storms between 1992 and 1993; therefore, specifics in relation to the December 1992 Nor'easter are not always identified. However, the December 1992 Nor'easter was the largest storm considered in the Coastal Erosion Task Force Report. Jones Island Beach, Fire Island, and Westhampton Beach from Moriches Inlet to Shinnecock Inlet lost significant amounts of beach width. Other areas where localized beach erosion problems were reported are several parks along the shorelines of Gardiner's Bay, the causeway of Orient Point, Callahan's Beach and Schubert Beach in Smithtown, Asharoken, and Bayville. A variety of sources were used to develop an inventory of problems caused by the December 1992 Nor'easter and the lesser storms that followed, ending with the late winter blizzard/nor'easter of March 1993. The inventory of coastal erosion problems within SC, between the identified time periods, is outlined below: South Shore Barrier Islands · Jones Beach Island: Severe erosion occurred on Tobay and Gilgo Beaches, and extensive dune scarping occurred. Flooding damaged mechanical and electrical equipment at the Jones Beach Theater. · Fire lsland: Extensive beach erosion at Robert Moses State Park rendered swimming areas virtually useless. Approximately 1,000 feet of the park's primary dune was damaged. The basin was damaged extensively and embankments and roads were washed out. Severe beach erosion occurred from Kismet to Davis Park, at Long Cove and at Old Inlet. Smith Point County Park also had severe erosion and dune scarping. Most Fire Island communities suffered widespread dune scarping and washovers. Kismet, Fair Harbor, Dunewood, Old Lonelyville, Robins Rest and Atlantique were particularly hard hit. As of early June 1993, 44 houses were reportedly destroyed and another 42 were seriously damaged, including homes in the Villages of Saltaire and Ocean Beach. Other damages occurred to the Ocean Village Marina, Fire Island Ferry Dock and Bayside Marina in Altantique (Town oflslip). Washovers in Atlantique, within the Fire Island National Seashore Wilderness Area, and in Smith Point County Park have rendered these locations highly susceptible to breaching. Several barrier island communities in the Town of Brookhaven experienced beach and dune erosion and destruction of oceanfront homes, particularly in Ocean Bay Park. · Moriches lnlet to South Shore Mainland Atlantic Shoreline: More than half of the beach area eroded at a 1.5 mile stretch of Westhampton barrier in the Town of Southampton, which led to two breaches through the barrier island west of the Westhampton Groin Field. More then 85 residences were destroyed in this Westhampton barrier. The December 1992 Nor'easter reportedly caused 16 major dune washovers and bayside road flooding. Quogue and Tiana Beaches were extensively damaged and subject to widespread dune scarping and a number of DMA 2000 Hazard Mitigation Plan ' Suffolk County, New York [T~1 DRAFT- September 2007 5.4.5-41 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION washovers. Overwash destroyed a section of Dunes Road, blocking access to facilities of the Shinnecock Fishermen's Cooperative. South Shore Mainland Atlantic Shoreline East Hampton: In East Hampton, Sagg Main Beach, Indian Wells Beach, Main Beach, and Hither Hills State Park Beach eroded. Two coastal ponds were observed to have reopened inlets after the December 1992 Nor'easter. Also, moderately severe to severe dune erosion, major washovers, and 17 bluff slumps were observed as a result of the 1992 storm. Peconic Bays to Gardiners Bay Gardiner's Bay/Napeague Bay Complex: Ditch Plains Beach lost 25 feet of beach width. Shagwong Beach and Sammy's Beach lost approximately 50 feet and 60 feet of beach width. S. ammy's Beach also was subject to severe bluff erosion. North Shore East of Mount Sinai: Beach erosion caused a washout in the Orient Beach Causeway. Severe beach erosion between Rocky Point and Wading River allowed significant wave attack causing damage to seawalls and undercutting the bluffs. The extensive bluff erosion damaged a few homes and left over 100 homes with a limited setback from the new edge of the receded bluff. The Town of Smithtown reported that numerous erosion and .storm damage problems had occurred along Smithtown Bay, including: - Damage to dunes and the pedestrian accessway in Long Beach; - Beach loss/erosion; Bluff erosion; - Damage to staircase/parking area retaining wall; - Damage to parts of the stormwater drainage system of Callahan's Beach; - Bluff slumping and undermining of a parking lot at King's Park Bluff (Old Dock); - Dune loss and staircase damage at Schubert Beach; - General damage to marinas, floats, mooring areas, boat launches, parking lots, roadways and navigation channels. West of Mount Sinai: Severe erosion of the Asharoken Strip occurred downdrift of the LILCO Northport power station discharge canal and jetties. When overwash occurred during the December 1992 storm, the low-lying section of Asharoken Avenue was heavily damaged and utility lines were destroyed, isolating Eaton's Neck. Approximately 20 to 30 feet of blufferosion in Asharoken was reported. (Cuomo, 1994).

Source: Mandia, 1992 Note: In Saltaire and much of Fire Island, the 1992 Nor'easter washed away much of the beach, leaving the shoreline severely eroded and houses toppled into the sea. March 12-15, 1993 ("Superstorm of 1993," "Storm of the Century," or "Great Storm of 1993"): This storm was identified as a Nor'easter and a blizzard. It resulted in a FEMA Emergency Declaration (EM), including SC, identified as FEMA EM-3107. This storm reportedly caused a total of $6.6 billion in damages along the eastern coast of the U.S and resulted in over 270 fatalities (23 fatalities in NYS) (Lott, 1993). According to NYSEMO, the 1993 blizzard resulted in total eligible damages of approximately $8.5 million throughout NYS. Damage on Fire Island was extensive. The New York Times reported that the storm was so powerful that it scoured from 70 to 100 feet of beach away from Fire Island, almost the entire length of the island. Dunes were reduced to 0 to 8 feet in most places from their previous 15 to 25 feet (Ocean Beach of Fire Island, 2002). According to a Patchogoe Village HMP, at least 18 homes fell into the sea on Long Island due to the pounding surf. This storm was the 4th costliest storm in U.S. history (Patchogue Village, Date Unknown). Many impacts associated with this event are represented under the December 1992 details identified above. Specific monetary losses for SC are not documented. October 14, 2005 (Remnants of Hurricane Wilma): According to the NOAA-NCDC storm query for SC, this event resulted in $11 million in property damages and significant coastal erosion. According to New York Congressman Tim Bishop in a November 30, 2005, news release, this event resulted in the south shore of Long Island, particularly large portions of SC, to experience massive flooding and significant storm damage including erosion. According to the 2006 State of the Beach report by Surfrider DMA 2000 Hazard Mitigation Plan - SuffOlk County, New York 5.4.543 DRAFT - September 2007 SECTION 5.4,5: RISK ASSESSMENT - COASTAL EROSION Foundation, in the winter of 2005 to 2006, beaches and dunes on .the South Shore of Long Island and bluffs on the island's north shore sustained significant erosion from this storm. April 14-16, 2007 ("The Beast From the East"): The Spring Nor'easter of 2007 was a nor'easter that affected mainly the northeastern parts of the U.S. during its three day course from April 14 to April 16, 2007. The combined effects of high winds, heavy rainfall, and high tides led to coastal erosion, flooding, storm damages, power outages and evacuations, and disrupted traffic and commeme. The storm impacted the New York area before dawn with pounding wind and rain. The storm sent tides surging against coastal beaches and riverfront communities. On Fire Island, where winds up to 50 mph moved in from the ocean, more than 1,000 people voluntarily evacuated (McFadden, 2007). Coastal erosion was also identified in Shirley at the Smith Point County Park, as can be seen in Figures 5-128 through 5-130. In Davis Park, high tides chewed through 30 feet of protective dune -- destroying decks, mangling staircases~ and shattering cesspools at half a dozen houses. Waves scooped significant amoufits of sand from beneath approximately twelve homes along the beach, leaving some to wont the worst was still to come. The storm stole away ground that had been precious to this small community of beach-goers for decades. Fire Island National Seashore officials said the sands' disappearance has been a long time coming. "In some ways it's not a surprise, because it's been a narrow beach and the ocean's been right there," said park superintendent Mike Reynolds. "The beach conditions in that spot were bad to begin with." Elsewhere on Fire Island the damage was less severe. To the west, in Atlantique Beach, high waves had washed over the dunes in several locations and bits of snow fencing tom out of the dunes were scattered on the beach as dark gray waves 10 to 15 feet tall and topped with breaking crests thundered ashore. Piles of sand were deposited on the walkways leading from the beach. And in Ocean Beach, Fire Island's largest community, water stood in the streets of the business ama and adjacent residential blocks, sometimes calf-deep as emergency vehicles moved through the ama (Madison & Smith, 2007). According to Jennifer Smith from Newsday, this April 2007 nor'easter produced erosion-related destruction throughout SC. Impacts were identified at the last edge of Captree State Park's picnic grounds, along a swath of beach at Smith Point County Park, and for some of the dunes that guard Ocean Parkway from the pounding surf of the Atlantic. SC officials conducting a damage assessment found that about 1/3 of the sand placed at Smith Point County Park 10 days earlier was washed away. County Executive Steve Lex,3, stated that there were no plans to replenish the lost sand. The total project cost to replenish the sand is estimated at $4.7 million. Figures 5-128 through 5-130, identify erosion of Smith Point County Park during the storm. On April 17, 2007, at high tide the Great South Bay engulfed 20 feet of beach that. betbre the storm, had bordered the pool at Hecksher State Park. Only a lip of turf, damaged trees, and a sliver of sand remained. Robert Moses State Park lost about 75 feet of usable beach during the storm. Farther west at Gilgo State Park, debris and tidewater breached the dunes during the storm up to 15 feet from Ocean Parkway. Down on the beach, the remnants of a former Coast Guard station protruded from the sand tSmith, 2007). On April 30. 2007, U.S. Senator Charles E. Schumer, SC Executive Steve Levy and Babylon Town Superx isor Steve Bellone toured storm-hammered areas in Gilgo Beach in the Town of Babylon to assess the damage and discuss the recovery efforts from the destructive April 2007 Nor'easter. This storm caused over $26 Million in damage in SC, including significant erosion, flooding, and harm to homes, businesses, and infrastructure. In an effort to ensure that Long Islanders received help, Schumer called on. the President to immediately issue a disaster declaration to release all available assistance to residents and communities. Babylon officials said many town beaches have lost up to 100 feet annually in the last five years because of erosion, and this storm made the situation even worse. Some of the dunes that guard nearby Ocean Parkway from the surf of the Atlantic Ocean were lost. Debris and tidewater that breached the dunes during the storm sat a mere 15 feet from Ocean Parkway. Without immediate remediation, another major storm could threaten the integrity of Ocean Parkway and destroy Gilgo Beach, a major DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.544 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION commuter highway with sewer pipes running through it. Cupsogue Beach County Park in Westhampton was hit with over $5 million in damage while millions more in damage affected Smith Point County Park in Shirley. Major erosion and flooding also occurred at places like Captree State Park (Figure 5-131), Heckscher State Park, Caumsett State Park, Orient Beach, and Montauk Point. The storm led to the partial collapse of a road at Orient Point State Park. Homes in Davis Park in Fire lsland were left wobbling over the sea after high tides consumed the sand beneath them (Figure 5-132). High storm tides battered away 30 feet of protective dune that once guarded wooden pilings beneath a dozen homes in the small community, leaving some at risk of collapse. The waves decimated decks, stairways, and cesspools (Schumer, 2007) As of May 3, 2007, FEMA announced that SC, along with other counties, were declared a disaster area, eligible for Public Assistance (PA) (FEMA DR-1692). Disaster assistance was approved for state and local government [termed PA] and certain private non-profits in 12 counties, including SC, for this Nor'easter event (Figure 5-133). Disaster aid totals for SC has not been reported (FEMA, 2007). Figure 5-128.

FEMA-1692-DR April 2007 Nor'easter Source: (FEMA, 2007) Probability of Future Events As indicated in the FEMA Multi-Hazard Identification and Risk Assessment Report, coastal erosion is measured as the rate of change in the position or horizontal displacement of a shoreline over a specific period of record, measured in units of feet or meters per year. Erosion rates vary as a function of shoreline type and are influenced primarily by episodic events. Monitoring of shoreline change based on a relatively short period of record does not always reflect actual conditions and can misrepresent long term erosion rates. Shorelines that are accreting, stable, or experiencing mild rates of erosion over a long- term period are generally considered as not subject to erosion hazard. However, short-term and daily erosion can expose a segment of coast to an episodic storm event and associated erosion 'damages at any given time. Detailed methods of determining return periods and frequencies of occurrence of coastal erosion are very difficult to determine due to limited information and the relatively short period of recorded data in most areas. The long-term pattems of coastal erosion are also difficult to detect because of substantial and rapid changes in coastlines in the short-term (that is, over days or weeks from storms and natural tidal processes). It is usually severe short-term erosion events, occurring either singly or cumulatively over a few years, that cause concern and lead to attempts to influence the natural processes. Analysis of both long- and short-term shoreline changes are required to determine which is more reflective of the potential future shoreline configuration. DMA 2000 HaZard Mitigation Plan - Su.olk County, New Yoik DRAFT - September 2007 5.4.5-48 SECTION 5,4.5: RISK ASSESSMENT - COASTAL EROSION Long Term Erosion Coastal erosion may be a result of multi-year impacts and long-term climatic change such as sea-level rise, lack of sediment supply, subsidence, or long-term human factors such as the construction of shore protection structures and dams or aquifer depletion. These trends have caused the shoreline to shift landward across the present-day continental shelf during the last 15,000 years. SC is predominantly surrounded by coastal waters from the Atlantic Ocean and the Long Island Sound; therefore, long term erosion is an ongoing process for most areas along the coast of SC. Short term Erosion Coastal erosion can occur from rapid, short-term daily, seasonal, or annual natural events such as waves, storm surge, wind, coastal storms, and flooding or from human activities including boat wakes and dredging. The most dramatic erosion often occurs during storms, p.articularly because the highest energy waves are generated under storm conditions. Short term erosion can be seen in the photographs taken along the shore of Smith Point County Beach during the April 2007 storm (Figures 5-128 and 5-130). As presented in an abstract by Keqi Zhang, Bruce Douglas, and Stephen Leatherman in The Journal of Geology of the University of Chicago in 2002, in a few hours or days, scores of meters of beach width can be lost due to a severe storm. However, newly available shoreline data from the U.S. East Coast show that beaches recover after storms to positions consistent with their long-term (100+ yearr) trend. Even the largest storms, such as the Ash Wednesday Storm of 1962, considered to be the most damaging in the twentieth century, appear to have had little effect on long-term trends. The gradual recession of beaches along the U.S. East Coast is mainly controlled by other factors such as sea-level' rise and variations of sediment supply. Therefore, it follows that barrier beaches in a coastal plain setting would not experience long-term erosion in response to storm impacts if the sea were to stop rising and sediment supply did not change (Zhang, Douglas, Leatherman, 2002). Based on the 1999 National Assessment of Coastal Vulnerability to Sea-Level Rise: Preliminary Results for the U.S. Atlantic Coast, USGS Open-File Report 99-593 prepared by E. Robert Thieler and Erika S. Hammar-Klose of USGS, increasing sea level rise appears to be the main problem affecting U.S. coastlines, resulting in increased erosion, flooding, and storm damage. This study focuses on determining the physical response of the coastline to sea-level rise, which has been identified as one of the most important applied problems in coastal geology. Prediction of shoreline retreat and land loss rates is critical to the planning of future coastal zone management strategies, and to assessing the biological impacts of habitat changes or destruction. Presently, long-term (greater than 50 years) coastal planning and decision-making has been done piecemeal, if at all, for the nation's shoreline (National Research Council, 1990; 1995). Consequently, facilities and at times entire communities are being developed without adequate consideration of the potential costs of protecting or relocating them from sea level rise- related erosion, flooding and storm damage. Although a viable, quantitative, predictive approach is not available, the relative vulnerability of different coastal environments to sea-level rise may be quantified at a regional to national scale using basic information on coastal geomorphology, rate of sea-level rise, past shoreline evolution, and other factors. The overall goal of this study is to develop and utilize a relatively simple, objective method to identify those portions of the U.S. coastal regions at risk and the nature of that risk (e.g., inundation, erosion, etc.). The long-term goal of the 1999 USGS study was to predict furore coastal changes with a degree of certainty useful for coastal management, following an approach similar to that used to map national seismic and volcanic hazards. DMA 2000 Hazard Mitigation Plan 2 Suffoik c0uniyl N;W ~ork 5A15:49 DRAFT- September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION In this study, the relative vulnerability of different coastal environments to sea-level rise is quantified for the U.S. East Coast. This initial classification is based upon variables such as coastal geolnorphology, regional coastal slope, and shoreline erosion and accretion rates. The combination of these variables and the association of these variables to each other furnish a broad overview of regions where physical changes will occur due to sea-level rise. Coastal erosion and accretion rates are grouped as one of six risk variables used to create the Coastal Vulnerability Index (cvI), which was created as a means to determine coastal vulnerability to sea level rise in the U.S. The index allows the six physical variables to be related in a quantifiable manner. Iris method yields numerical data that cannot be directly equated with particular physical effects. It does, however, highlight those regions where the various effects of sea- level rise may be the greatest. For the purpose of this HMP, the erosion/accretion variable is the only one that applies to this hazard profile; therefore, all other variables are not discussed. Shoreline erosion and accretion rates for the U.S. were compiled into the Coastal Erosion Information System (CEIS), which is a computerized database of a data collected by Dolan and Kimball of the University of Virginia. The data presents shoreline rates of change for various geography regions of the U.S. The data is drawn from a wide variety of sources, including published reports, historical shoreline change maps (for example, CEHA maps), field surveys, and aerial photo analyses. However, the lack of a standard method among coastal scientists for analyzing shoreline changes has resulted in the inclusion of data utilizing a variety of reference features, · measurement techniques, and rate-of-change calculations. Thus, while CEIS represents the best available data for the U.S. as a whole, much work is needed to accurately document regional and local erosion rates. The CEIS data are being augmented by, and updated with, shoreline change data obtained from states and local agencies, in addition to new analyses being conducted to determine regional and local erosion rates. Risk rankings of erosion and accretion rates for Long Island were identified as presented in Figure 5-134. The risk rankings of erosion/accretion along the Long Island shorelines range between a moderate to very high risk (USGS, 2001 ).

DMA 2000 Hazard Mitigation Plan - suffolk countyl New York DRAFT- September 2007 5.4.5-51 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. While coastal erosion is not generally considered an imminent threat to public safety, its impact to property, infrastructure, environmental resources and local economies is clear. The following text evaluates and estimates the potential impact of coastal erosion on SC including: · Overview of vulnerability · Data and methodology used for the evaluation · Impact on ( 1 ) life, health and safety; (2) general building stock; (3) critical facilities; and (4) economy. · Further data collection that will assist understanding of this hazard over time · Overall vulnerability conclusion Overview of Vulnerability Coastal erosion is a significant concern to SC because of large number of communities and cultural resources (beaches, parks, etc.) located along the coast. As described in detail earlier in this profile, principal natural causes of erosion are wave action, wind action, and overland rtmoff through intense precipitation. Other contributing factors that can significantly increase erosion of a natural protective feature include length of fetch, wind direction and speed, wave length, height and period, near-shore water depth, tidal influence, increased lake levels, and overall strength and duration of storm events. 'Additionally, sea-level rise will exacerbate coastal erosion. As identified in USGS Open-File Report 99- 593, through using all the variables identified in Table 5-36 of the CVI, Figure 5-135 identifies the coastal vulnerability to sea-level rise along the shorelines of Long Island, NY. Those areas most at risk within SC, are located along the south shore, primarily along the barrier beaches and islands and are vulnerable to coastal erosion. Fire Island appears to be most at risk of coastal losses in the future. Table 5-36.

EXPLANA1 ION COASTAL VULNERABILITY INDEX :~ourcc: USGS, 2001 Data and Methodology Step 4 in FEMA's How-To 386-2 discusses the loss estimation process. For erosion damage, FEMA states "Unfortunately, current standard loss estimation models and tables for erosion damages are not ax ailable. As a result, you may wish to simplify your consideration of structure damage so that buildings arc assumed to be either undamaged or severely damaged due to erosion. Although slight or moderate dalnage can occur due to erosion, the likelihood of this level of damage is considered small. Your csmnated structure loss from erosion should be based on past experience, the location of the structure within the hazard area, rate of erosion, and the structure replacement value." itt:;} DMADRAFT2000_ SeptemberHazard Mitigation2007 Plan - Suffolk County, New York 5.4.5-53 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION Available data was used to assess SC's vulnerability to coastal erosion. For the purposes of this risk assessment, the CEHA data provided by NYSDEC (CEHA line and the l~000~foot seaward buffer) was used as the hazard area. However, the average rate of recession is not defined for the entire SC hazard area (Figures 5-111 through 5-117). The asset data (population, building stock and critical facilities) presented in the County Profile section (Section 4) was used to support an evaluation of assets exposed and the potential impacts and losses associated with this hazard. To determine what assets are exposed to coastal erosion, available and appropriate GIS data was overlaid upon the hazard area. Impact on Life, Health and SafeR, Coastal erosion is not generally considered an imminent threat to public safety (FEMA Multi-Hazard ID and RA). Impact on General Building Stock The SC Real Property provided parcel centroids for land pamels located in SC by tax map number. To estimate the number of parcels exposed to coastal erosion, the parcel centroids were overlaid upon the coastal erosion hazard ama (CEHA line and 1,000-foot seaward buffer). Of the 728,401 parcel centroids provided by SC Real Property, 6,729 parcels (or 0.92% of the pamels in SC) are located within the coastal hazard area. Table 5-37 lists the estimated number of parcels exposed to coastal erosion in SC. Table 5-37. Estimated Number of Parcels in the CEHA Jurisdiction Babylon 180 Brookhaven 1,106 East Hampton 879 Huntington 570 Islip 703 Riverhead 369 Shelter Island 77 Smithtown 95 Southampton 1,684 Southold 1,066 TOTAL 6,729 Source: Real Property Database; NYSDEC. Building assessed value data by pamel was provided from the SC Treasurer's Office. However, only 49% (3,298 parcels) of the Real Property parcel centroids could be joined to the Treasure's Office assessed value data by tax map number. Of the 3,298 parcels with buildings, the total building assessed value is $75.1 Million. If one assumes the remaining 51% ofpamels contain roughly the same building assessed value, this figure can be doubled. Therefore, the estimated total assessed value of buildings located in the costal erosion hazard area is $150 million. Sufficient data was not available to estimate coastal erosion damages to the general building stock. In general, estimated damages due to coastal erosion could be severe to communities located within the coastal erosion hazard area. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT- September 2007 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION Impact on Critical Facilities There are no police stations, fire/EMS facilities, schools, EOCs, medical facilities or shelters located with in the coastal erosion hazard area. Impact on Economy According to the SC Planning Department "The population of eastern SC increases substantially during the summer months because of tourism and the presence of seasonal homes." The beaches, parks and coastal communities in SC are a huge draw for tourists in the summer months which substantially contribute to the County's economy. According to SC Legislature's Budget Review Office report entitled Impact on the Atlantic Ocean Beaches to the Economy of SC (2003), an estimated 9.1 million tourists visit Long Island annually, with 5.5 million visiting SC. An estimated 11.3 million people are estimated to visit SC's south shore beaches each year, and of these, 500,000 (or 4.6%) are estimated to be tourists. Table 5-38 lists the beaches, parks and residential and natural communities located within the CEHA jurisdiction that are could be impacted by coastal erosion. Table 5-38.

It is estimated that direct spending .or output from SC's south shore beaches contributes approximately $255.7 million annually to the County's economy (measured in 1999 dollars), supporting 3,855 jobs and $99 million in labor income. Information was not found regarding the north shore beaches' contribution to the SC economy. It is clear that impact to SC beaches, from coastal erosion or other natural hazards, would impact the local economy. Coastal erosion can also severely impact SC's roads and infrastructure. There are 6.9 miles of parkway and State roads that lie within the CEHA jurisdiction and therefore, exposed to coastal erosion. These include: Robert Moses State Parkway, Ocean Parkway (State Route 909), and State Routes 25, 27 and 48. Additionally, there are 383.7 miles of secondary (local) roads that lie within the CEHA. There are two bridges, located at the intersection of Main Street and Gardiners in the Town of Southold, located within the CEHA. There are no railroad stations, railway lines, or airports vulnerable to coastal erosion. Of the electrical power facilities, substations, and potable water facilities, none are located within the CEHA; · however, there are four substations located on the barrier islands in the Town of Islip and one substation located on Fire Island in the Town of Brookhaven. One military installation, the U.S. Neck Coast Guard Station in the Village of Asharoken, has property located in the CEHA jurisdiction that could be impacted by coastal erosion. As described earlier, Sewer District 3's sewer outfall is highly vulnerable to coastal erosion. Traversing through the barrier island and 2.5 miles into the Atlantic Ocean, the outfall disposes treated sewage for the Towns of Babylon and lslip. The original construction of the outfall had cover over the pipe at the shoreline approximately 17 feet. Storms have reduced that cover to 8 feet at the shoreline and less to the south. In 1992, a project was implemented ($3.5 million) to install 700 feet of sheeting with a rehabilitated cathodic protection system at the shoreline. According to SC DPW, preliminary assessments indicate that the system does not have the 100oyear life, as projected in 1980 (Wright, 2007). DMA 2000 Hazard Mitigation Plan 2 §~ffoik o~nty, New York DRAFT- September 2007 5.4.5-57 SECTION 5.4.5: RISK ASSESSMENT - COASTAL EROSION Additional Data and Next Steps When the CEHA maps are updated, this section of the plan will be updated to reflect new areas and/or assets located in the coastal erosion hazard area. Additional data on historic costs incurred to reconstruct buildings and/or infrastructure due to coastal erosion impacts would assist in estimating future losses. Expanding upon the SC Real Property database to include data regarding whether a building is present on a parcel, building square footage, the type of construction, year built, and building replacement cost/value would enable a more accurate assessment of exposure and loss estimates over time. Overall Vulnerability Assessment SC is highly vulnerable to coastal erosion events which can cause significant impacts and losses to natural resources (i.e., beaches, parks, barrier islands), buildings and infrastructure. Existing and future mitigation efforts should continue to be developed and employed that will enable the study area to be prepared for these events when they occur. The overall hazard ranking determined by the Planning Committee for this hazard is high (see Tables 5-6 and 5-7). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.5-58 DRAFT- September 2007 SECTION 5.4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION 5.4.6 NATURAL GROUNDWATER CONTAMINATION This section provides a profile and vulnerability assessment for the Natural Groundwater Contamination hazard. Although groundwater contamination is caused by natural and manmade origins, this HMP only fbcuscs on natural hazards affecting thc SC area; therefore, this HMP only focuses on natural groundwater contamination. ItAZARD PROFILE This section provides profile information including: description, location and extent, previous occurrences and losses and the probability of future occurrences. Description Groundwater is a natural resource that is used for drinking water, ~recreation, industry, and crops. It is water found underground in the cracks and spaces in soil, sand, and rock. Groundwater is stored in-and moves slowly through-layers of soil, san& and rocks called aquifers. Aquifers typically consist of gravel, sand, sandstone~ or fractured rock, like limestone. These materials are permeable because they have large connected spaces that allow water to flow through. The speed of groundwater flow depends on the size of the spaces in the soil or rock and how well the spaces are connected. The area where water fills the aquifer is called the saturated zone (or saturation zone). Thc top of this zone is called the water table. The water table may be located only a foot below the ground's surface or it can be hundreds of feet down. Groundwater can be found almost everywhere. The water table may be deep or sh~.llow; and may rise or fall depending on many factors. Heavy rains or melting snow may cause the water table to rise. Heavy pumping of groundwater supplies may cause the water table to fall. Water in aquifers is brought to the surface naturally through a spring or can be discharged into lakes and streams. Groundwater can also be extracted through a well drilled into the aquifer. A well is a pipe in the ground, which generally includes a permeable screen that allows groundwater to flow into the well. This water can be brought to the surface by a pump. Shallow wells may go dry if the water table falls below the bottom of the well. Some wells, called artesian wells, do not need a pump because natural pressure is sufficient to force the water up and out of the well. Groundwater supplies are replenished, or recharged, by rain and snow melt. Much of the United States depends on groundwater supply for freshwater withdrawals, agricultural use (mostly for irrigation), public water supply withdrawals, and primarily for drinking water (particularly in rural populations). In some areas of the world, people face serious water shortages because groundwater is used faster than it is naturally replenished or because groundwater has been polluted by human activities. In areas where material above the aquifer is permeable, pollutants can readily sink into groundwater supplies (Groundwater Foundation, 2007). Groundwater contamination is defined as the addition of elements, compounds, and/or pathogens to groundwater that alter its composition. In general, shallow, permeable water table aquifers are the most susceptible to contamination, but susceptibility of all aquifers to contamination is determined largely by such site-specific characteristics as: · distance from the contamination source to the aquifer and residence time of the water in the unsaturated zone; · presence of clay and organic matter in the unsaturated zone materials; · potential of a particular contaminant to biodegrade and decompose; · amount of precipitation, which affects recharge and the rate at which contaminants move downward; DMA 2000 Hazard Mitigation Plan - Suffolk County, Ne, w York 5.4.6-1 DRAFT- September 2007 SECTION 5.4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION cvapotranspiration, 'which in recharge areas may decrease thc amount of watcr that moves downward to thc aquifer. Groundwater can be contaminated in many ways and through varicty of compounds, both of natural origin and man-made. Contamination sources can bc grouped into five main categories: natural, municipal, agricultural, industrial and residential. Most concern over groundwater contaminatioo has centered on pollution associated with human activities~ including municipal, agricultural, industrial and residential uses. Human groundwater contamination can be related to waste disposal [private sewage disposal systems (septic systems), land disposal of solid waste (landfills), municipal wastewater, wastewater impoundments, land spreading of sludge, brine disposal from the petroleum industry, mine wastes, deep-well disposal of liquid wastes, animal feedlot wastes, radioactive wastes] or not directly related to waste disposal (accidents, certain agricultural activities, mining, highway deicing, acid rain, improper well construction and maintenance, road salt). It can be caused by the improper handling, transporting, stockpiling and storage of hazardous materials (e.g. underground or aboveground storage tanks) resulting in leaks or spills or poor housecleaning practices. Since groundwater contamination associated with human influence is not considered a natural hazard; only natural groundwater contamination is being assessed within this hazard profile for the purpose of this HMP. Natural groundwater contamination is contamination of groundwater that is not associated with human 'gctivities. Groundwater contains some natural impurities. The types and concentrations of' natural impurities depend on the nature of the geological material through which the groundwater moves and the quality of the recharge water. Natural sources of groundwater contamination refer to an assortment of water quality pioblems, including: natural deposits of salts, gypsum, nutrients, and metals in soils that leach into surface and ground waters; warm weather and dry conditions that raise water temperatures, depress dissolved oxygen concentrations, and dry up shallow water bodies; and low-flow conditions and tannic acids from decaying leaves that lower pH and dissolved oxygen concentrations in swamps draining into streams. Groundwater moving through sedimentary rocks and soils may pick up a wide range of inorganic compounds such as magnesium, calcium, and chlorides. Some aquifers have high hatural concentrations of dissolved constituents such as arsenic, boron, and selenium. The effect of these natural sources of contamination on groundwater quality depends on the type of contaminant and its concentrations. Most inorganic compounds are harmless at the concentrations commonly found in unpolluted groundwater, and some are even beneficial to human health. Naturally occurring pollutants of groundwater include, but are not limited to, the following: · Microorganisms: Bacteria, viruses, parasites and other microorganisms are sometimes found in water. Shallow wells, with water close to ground level, are at most risk. Runoff, or water flowing over the land surface, may pick up these pollutants from wildlife and soils. This is often the case after flooding. Some of these organisms can cause a variety of illnesses. Symptoms include nausea and diarrhea. These can occur shortly after drinking contaminated water. The effects could be short-term yet severe (similar to food poisoning) or might recur frequently or develop slowly over a long time. A common type of microorganism in groundwater is Coliform Bacteria. Coliform Bacteria occurs naturally in the environment and is associated with soils and plants and in the intestines of humans and other warm-blooded animals. This bacterium is used as an indicator for the presence of pathogenic bacteria, viruses, and parasites from domestic sewage, animal waste, or plant or soil material. · Dissolved Solids and Chlorides: One of the most common water quality concerns is the presence of dissolved solids and chloride in concentrations that exceed the recommended maximum limits OMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.6-2 DRAFT- September 2007 SECTION 5.4,6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION in federal secondary drinking water standards. The recommended limit are 500 mg/L (milligrams per liter or approximately equivalent to parts per million) for dissolved solids and 250 mg/L for chloride. Such concentrations are found at thc seaward ends of all coastal aquifers and tire quite common in aquifers at depths greater than a few hundred feet below the land surface in many parts of the United States. · Radionuclides: Radionuclides are radioactive clements such as Gross Alpha particles, Beta particles and photon emitters, Radium 226 and Radium 228 (combined), and Uranium. They may be present in underlying rock and ground water and through erosion or decay of these natural deposits, groundwater contamination can occur. Most drinking water soumes have very low levels of radioactive contaminants ("radionuclides"), which am not considered to be a public health concern. Of the small percentage of drinking water systems with radioactive contaminant levels high enough to be of concern, most of the radioactivity is naturally occurring. · Radon: Radon is a gas that is a natural product of the breakdown of uranium in the soil -- can also pose a threat. Radon is most dangerous when inhaled and contributes to lung cancer. Although soil is the primary source, using household water containing Radon contributes to elevated indoor Radon levels. Radon is less dangerous when consumed in water, but remains a risk to health. · Nitrates and Nitrites: Although high nitrate levels are usually due to human activities (see below), they may be found naturally in ground water. They come from the breakdown of nitrogen compounds in the soil. Flowing ground water picks them up from the soil. Drinking large amounts of nitrates and nitrites is particularly threatening to infants (for example, when mixed in formula). Most groundwater not affected by human activity contains less than 10 mg/L nitrate- nitrogen, the maximum concentration allowed by federal primary drinking water standards. Nationwide, nitrate-nitrogen concentrations of less than 0.2 mg/L generally represent natural conditions, whereas values greater than 3 mg/L may indicate the effects of human activities. · Heavy Metals: Underground rocks and soils may contain inorganic chemicals, including arsenic, asbestos, barium, cadmium, chromium, copper, iron, lead, manganese, mercury and selenium. Erosion of these natural deposits can lead to the contamination of groundwater sources. However, these contaminants are not often found in household wells at dangerous levels from natural sources. - Arsenic: Arsenic occurs naturally in sedimentary and hard rocks and soil, water, air, and plants and animals. Natural arsenic is also found in thermal and mineral waters, which reach the earth's surface either by natural discharge in springs or by geothermal exploitation, which may affect thc environment if not treated or not reinjected. It can be further released into the environment through natural activities such as volcanic action, erosion of rocks and forest fires. Cadmium: Cadmium occurs naturally in zinc, lead, copper and other ores which can serve as sources to ground and surface waters, especially when in contact with soft, acidic waters. - Iron and Manganese: Although not particularly toxic, iron and manganese in concentrations greater than the limits for federal secondary drinking water standards (0.3 mg/L for iron and 0.05 mg/L for manganese) can impair the taste of water; stain plumbing fixtures, glassware and laundry; and form encmstations on well screens, thereby reducing well-pumping efficiency · Fluoride: Fluoride is helpful in dental health, so many water systems add small amounts to drinking water. However, excessive consumption of naturally occurring fluoride can damage bone tissue. High levels of fluoride occur naturally in some areas. It may discolor teeth, but generally levels are not high enough to present a health risk (USEPA, 2006). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.6-3 DRAFT - September 2007 SECTION 5.4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION Saltwater Intrusion Coastal zones contain some of thc most densely populated areas in tile world, including those coastal zones that comprise Long Island, NY. However, these regions face many hydrological problems like flooding duc to cyclones and wave surge, and drinking water scarcity duc to salt water intrusion into coastal aquifers. Features which affect coastal aquifers arc summarized in Figure 5-136. Fi tire 5-136. Features that affec! Coaslal Aquifers Relative sea level rise Coastal zone Human activities Changes in hyclrological regime Coastal aquifers 1 - Rivers & estuaries backwate~ effect Countermeasures j Source: (Kumar~ Date Unknown) When dealing with exploitation, restoration and management of fresh groundwater in coastal aquifers, the key issue is saltwater intrusion. Saltwater intrusion is a type of natural groundwater contamination, where the natural balance between freshwater and saltwater in coastal aquifers is disturbed by groundwater withdrawals and other human activities that lower groundwater levels, reduce fresh groundwater flow to coastal waters, and ultimately cause saltwater to intrude into the coastal aquifers making those aquifers no longer available for usc. Although groundwater pumping is the primary cause of saltwater intrusion along the coasts, lowering of the water table by drainage canals also can lead to saltwater intrusion. Other hydraulic stresses that reduce freshwater flow in coastal aquifers, such as lowered rates of groundwater recharge in sewered or urbanized areas, also can lead to saltwater intrusion, but the impact of such stresses on saltwater intrusion, at least currently, likely is small in comparison to pumping and land drainage (Kumar, Date Unknown). Under natural conditions, the seaward movement of freshwater prevents saltwater from encroaching into coastal aquifers, and the interface between freshwater and saltwater is maintained near the coast or far below land surface. This interface is actually a diffuse zone in which freshwater and saltwater mix, and is referred to as the zone of dispersion (or transition zone). However, this natural balancing process can be disrupted. Saltwater intrusion refers the replacement of fresh water in coastal aquifers by saltwater due to the motion of a saltwater body into the freshwater aquifer (Figure 5-137). Because saltwater has high concentrations of total dissolved solids and certain inorganic constituents, it is unfit for human consumption and many other anthropogenic uses. Saltwater intrusion reduces fresh ground-water storage and, in extreme cases, leads to the abandonment of supply wells when concentrations of dissolved ions, such as chlorides, exceed drinking-water standards. The problem of saltwater intrusion was recognized as early as 1854 on Long Island, NY, predating many other types of drinking-water contamination issues DMA 2000 Hazard Mitigation Plan - Suffolk County, New York, 5.4.6-4 DRAFT- September 2007 SECTION 5,4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION addressed in current news rcports (Barlow, 2005). Saltwater can contaminate a freshwater aquifer through several pathways, including: lateral intrusion from thc ocean (also identified by some as saltwater encroachment); upward intrusion from deeper, more saline zones of a ground-water system (also known as saltwater upconing); and by downward intrusion from coastal waters (vertical movement of saltwater). At present, many coastal aquifers in the world, especially shallow ones, experience an intensive saltwater intrusion caused by both natural and human-induced processes. Fi tire 5-137. Schematic Representation of Saltwaler Intrusion ~ge Groundwater flow Stmrce: (Ranjan, 2007) In nature, the freshwater-saltwatcr interface (Figure 5-138) seldom remains stationary. Large scale recharge into the aquifer as well as withdrawals from it, result in the movement of the freshwater- saltwater interface from one position to another. The movement will advance or retreat, dependifig on whether the freshwater flow through the aquifer is decreased or increased. Therefore, change in groundwater recharge directly affects the saltwater intrusion. Subsequently, saltwater intrusion of coastal aquifers will accelerate due to thc reduction of groundwater recharge. This could mean a reduction of fi'csh groundwater resources in coastal aquifers. Changes in climatic variables, such as precipitation and tc,npcrature, and the land-use change can significantly alter groundwater recharge rates for major aquifer systems and thus affect the saltwater intrusion (Ranjan, 2007). Sahwatcr intrusion is a natural process, but it becomes an environmental problem when excessive pmnpmg of fresh water from an aquifer changes the water pressure and intensifies the effect, drawing salt x~atcr into new areas. When freshwater levels drop, the intrusion can proceed further inland until reaching ;t pumped well. Then you may get saltwater out of the pump, which becomes no longer available for drinking or irrigation (Ranjan, 2007). When you pump out fresh water rapidly, you lower the height of the I¥cslmatcr in the aquifer forming a cone of depression. The salt water rises 40 feet for every I foot of fi'cshwater depression and forms a cone of ascension (see Figure 5-138). Intrusion can affect the quality or' xxmcr not only at the pumping well sites, but also at other well sites, and in undeveloped portions of an aquifer (Lenntech, 2005). To prevent this, more and more countries adopt extensive monitoring schemes aad numerical models to assess how much groundwater can be pumped without causing such effects.

Sall Water Intrusion Process Source: (Lenntech, 2005) Sea revel The degrqe of saltwater intrusion varies widely among localities and hydrogeologic settings. In many instances, the ama contaminated by saltwater is limited to small parts of the aquifer and has little or no effect on wells pumped for groundwater supply. In other instances, contamination is of regional extent and has substantially affected groundwater supplies (Kumar, Date Unknown). The extent of saltwater intrusion depends, among other factors, on the rate of freshwater discharge to the sea. Other factors include the total rate of groundwater that is withdrawn compared to the total freshwater recharge to the aquifer, the distance of the stresses (wells and drainage canals) from the source (or sources) of saltwater, the geologic s[ructure and distribution of hydraulic properties of the aquifer, and the presence of confining units that may prevent saltwater from moving veitically toward or within the aquifer. Moreover, the time required for saltwater to move through an aquifer and reach a pumping well can be quite long. The depth of the aquifer at the seaside, through which the saltwater intrudes the aquifer, also has a major effect on the degree of intrusion. Depending on the location and lateral width of the transition zone, many years may pass before a well that is unaffected by saltwater intrusion suddenly becomes contaminated (Barlow, 2003). This makes saltwater intrusion a management problem, since the freshwater discharge to thc sea is the sum of the natural and the artificial recharge minus pumping. However, controlling saltwater intrusion is costly and/or management intensive. Extensive studies have been carried out in many parts of thc world to clarify the mechanism of saltwater intrusion and to control it from better exploitation of coastal aquifers (Amer, 1999). Location and Extent The aquifer system of Long Island is part of the Northern Atlantic Coastal Plain aquifer system that extends from Long lsland, New York, through North Carolina. This is a thick, multi-layered aquifer system that underlie thousands of square miles (Barlow, 2003).. Long Island's groundwater system is one of the largest and most important groundwater systems in NYS supporting over 3 million people. Its groundwater system has been designated by the USEPA as a sole-soume aquifer (SSA), which is defined as an aquifer that supplies at least 50 percent of the drinking water consumed in the overlying area and that, if contaminated, would create a significant hazard to public health (Cartwright, 2004). The aquifer system beneath SC consists of a sequence of unconsolidated deposits comprising three aquifers that overlie a southeastward-dipping bedrock surface. Sediment thickness ranges from about 500 feet in the northwest to almost 2,000 feet beneath the barrier beaches in southwestern SC. The uppermost aquifer is the Pleistocene-aged upper glacial aquifer, which is about 700 feet thick in the northern half of the island and generally thins to about 100 feet thick in the south. It is found within the upper Pleistocene dePOSits, which consist primarily of two terminal moraines, outwash, glaciolacustrine deposits, and DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.6-6 DRAFT- September 2007 SECTION 5,4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION marine clay on thc extreme south shore. Till, an unsorted mixture of clay, sand, gravel and boulders, is found mostly along thc north shore and in thc moraines. Outwash deposits that consist of fine to very coarse quartzosc sand and gravel are found between and south of thc moraines. Glaciolacustrine deposits that consist of silt, clay, aud some sand and gravel arc found mostly in central and eastern SC. Most private wells in thc county arc completed in thc upper glacial aquifer: Below the upper glacial aquifer is the Cretaceous-aged Magothy aquifer, which ranges in thickness fi'om 0 in extreme northwestern SC to more than 1,000 feet in thc south and extends as deep as 1,200 feet below land sur/hcc. The Magothy aquifer is within the Magothy Formation and Matawan Group, undifferentiated, and it consists of fluviodeltaic sediments deposited in a coastal plain environment. Sediments in the Magothy aquifer include fine to medium sand, clayey in part, with interbedded lenses and layers of coarse sand and sandy and solid clay. Gravel is common in the basal 50 to 200 feet. The Magothy aquifer is generally less affected by surface contamination than the upper glacial aquifer and is more commonly tapped by public- water suppliers. The deepest aquifer (Lloyd aquifer) is part of the Cretaceous-aged Raritan Formation and is separated from the Magothy aquifer by the Raritan confining unit. There are very few public-supply wells that penetrate the Lloyd aquifer (Cartwright, 2004). The water table is highest along the center of the island. This is also where the greatest rainfall occurs. Groundwater tends to flow from recharge areas in the center of the island to discharge areas along the north and south shores. The total depth of the Long Island Aquifer System is smallest on the north shore (approximately 600 feet) and deepest along the south shore (approximately 2,000 feet) (SCWA, 2007). SC, with nearly 1.5 million people and covering an area of 884 square miles (2006 U.S. Census estimate), is completely dependent on groundwater for all of its freshwater needs. Recharge comes solely from precipitation. The recharge in the area is 990 million gallons per day (MGD). The total capacity of the aquifers underlying SC is about 70 trillion gallons. There are more than 600 public supply wells in SC. ' About 210 MGD are withdrawn by pumping with equal amounts coming from the Magothy and Upper Glacial. Most of this water is returned to the aquifer with consumptive loss estimated to be 95 MGD. The loss is through pumping, sewage systems, marine discharges and evapotranspiration associated with irrigation and lawn sprinkling. The Pine Barrens in SC is the last large nearly-undeveloped ama on Lo. ng Island, consisting of some 100,000 acres and lies within the deep recharge zone of the Magothy aquifer. Due to limited development in the Pine Barrens, the ground water in this area is particularly pure (degradation of groundwater quality is inevitable wherever there are humans.) While the water is pure, extensive pumping would potentially harm the ecosystem by lowering the water table. Also, the high cost of pumping to developed areas would make use of this groundwater infeasible for the foreseeable future (ESERC, Date Unknown). The aquifer system of SC is highly vulnerable to contamination. A variety of soumes have indicated that groundwater contamination is present throughout SC; however, most documented contamination is primarily associated with human influences (e.g., pesticides, nitrates, heavy metals, hazardous releases and/or wastes) and not with natural contamination sources. Although there are many natural contaminants; those contaminants of natural origin that have been well documented for SC include radon, arsenic, and saltwater (through salt water intrusion). Other natural pollutants do impact the County; however, resources and documented cases regarding the location of natural contamination impacts is limited. The 1974 Safe Drinking Water Act and its 1986 amendments require the USEPA set standards for contaminants in drinking water that may pose health risks to humans. Drinking water standards apply to public water systems, which provide water for human consumption through at least 15 service connections, or regularly serve at least 25 individuals. Public water systems include municipal water companies, homeowner associations, schools, businesses, campgrounds and shopping malls. The USEPA standard for lifetime exposures in drinking water, the maximum contaminant level (MCL), isthe highest DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.6-7 DRAFT- September 2007 SECTION 5,4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION amount of a contaminant allowed in drinking water supplied by municipal water systems. Rcgulators usc thc reference dose to establish a MCI_ fora contaminant, assuming that thc exposure comes fi'om drinking 2 liters of contaminated water per day roi' 70 years (USEPA, 2006). Radon As required by the Safe Drinking Water Act, USEPA has developed a proposed regulation to reduce radon in drinking water. The proposed radon in drinking water role applies to all community water systems (CWSs) that use groundwater or mixed ground and surface water (e.g., systems serving homes, apartments, and trailer parks). The proposed rule would not apply to CWSs that use solely surface water, nor to non-transient non-community public water supplies and transient public water supplies (e.g., systems serving schools, office buildings, campgrounds, restaurants, and highway rest stops). Thc proposed regulation provides two options for the MCL of radon that is allowable in community water supplies. Thc proposed MCL is 300 picoCuries per liter (pCi/L) and the proposed alternate MCL is 4,000 pCi/L (USEPA, 2007). While most radon-related deaths are due to radon gas accumulated in houses from seepage through cracks in the lbundation, 30 to 1,800 deaths per year are attributed to radon from household water. Showering, washing dishes, and laundering can disturb the water and release radon gas into the air you breathe. Drinking water that has high levels of radon may be a health risk, but breathing air high in radon concentration is more harmful to your health. Breathing in radon gas over a long period of time can increase your risk of getting lung cancer. Drinking water contaminated by radon may increase your chances of developing stomach cancer. Virtually everyone has some level of radon in their water. The national average is 200 to 600 picocuries ' per liter. At these levels, scientists estimate the risk of developing cancer from radon ingestion is greater than thc risk of cancer from most other regulated contaminants found in drinking water at the maximum levels allowed by the USEPA. According to a groundwater study of 429 community water systems in NYS, SC was identified as having a Iox~ average of radon levels in its groundwater supply [less than 200 picocuries per liter between 1989 and l t>90 (Figure 5-139)]; however, this study is significantly outdated, does not represent all water systems, and may not represent the present day radon conditions.

Average Radon Levels of 429 Commtmity Water Syslems (1989-1990) Average radon levels in 429 community water systems (New York State Bureau of Public Water Supply Protection, <200 or no data 200-500 800,1100 1100,1400 1400,2700 270O-5400 >5400 Source: (NYSRP, Date Unknown) According to the SCWA 2006 Annual Drinking Water Quality Report, for the period of January 1, 2005 through December 31, 2005, 80 representative locations were tested for radon, for a total of 113 samples. The test results ranged from Non-Detect (no radon was detected) to 300 picocuries per liter (pCi/L). Those locations within SC that had detected levels of radon ranging between 200 and 300 picocuries include the Villages of Huntington and Huntington Bay, Amagansett, Bridgehampton, Montauk, Southampton/North Sea, Wainscott~ Watermill, Camp Hero Water District (CHWD) in Montauk and Riverhead Water District (SCWA, 2007). If indoor radon gas levels are high and groundwater is consumed in a household, it is advised that groundwater should be tested. If the radon level is low in the air, there is generally no need to test the groundwater. In general, 10,000 pCi/I of radon in water contributes roughly I pCi/l of airborne radon throughout thc house. The USEPA currently advises consumers to take action if the total household air level is above 4 pCi/1 (DPD, 2003). In regards to radon gas, according to the USEPA, all of Long Island has a low radon potential, with a predicted average radon screening level of less than 2 pCi/L (Zone 3). Figure 5-140 was developed using five factors to determine radon potential: indoor radon measurements; geology; aerial radioactivity; soil permeability; and, foundation type. Radon potential assessment is based on geologic provinces. Radon lndex Matrix is the quantitative assessment of radon potential. Confidence Index Matrix shows the quantity and quality of the data used to assess radon potential. Geologic Provinces were adapted to county boundaries for thc Map of Radon Zones within NYS. Thc USEPA recommends that actions be taken to reduce indoor radon concentrations if thc primary living areas of a home have radon concentrations above 4 pCi/L.

Arsenic On January 22, 2001 the USEPA adopted a new standard for arsenic in drinking water at 10 parts per billion (ppb), replacing the old standard of 50 ppb. The rule became effective on February 22, 2002. The date by which systems must comply with the new 10 ppb standard is January 23, 21)06. This standard for drinking water was establised to protect consumers served by public water systems from the effects of long-term, chronic exposure to arsenic (USEPA, 2006). Since May 2000, the U.S. Geological Survey (USGS) has published three maps summarizing a national data set on arsenic in groundwater. These maps were intended as a big-picture view of patterns in naturally occurring arsenic across the United States (Ryker, 2001). According to the May 2000 map (Figure 5-141), counties with arsenic concentrations exceeding possible new MCLs in 10 percent or more of groundwater samples between 1973 and 1997 were identified. This county map is based on 18,850 groundwater samples and shows arsenic concentrations in at least 10% of samples per county. SC had arsenic concentrations exceeding 3 parts per billion in 10 percent or more of samples. An update of this map was completed with 31,350 groundwater samples collected between 1973 and 2001 (Figure 5-142). This map indicated arsenic concentrations were identified in at least 25% of groundwater samples in each county, with arsenic concentrations ranging between 1 and 50 parts per billion. One location along the southern shoreline of SC appeared to have identified arsenic concentrations ranging between 10 and 50 parts per billion.

The databases of the SCWA and thc Suffolk County Department of Health Services (SCDHS) included 14 wells at which arsenic concentrations approached or exceeded the 2002 USEPA drinking-water guideline of l0 parts per billion (Cartwright, 2004). As a follow-up, I9 wells were sampled from June through August 2002; 7 were wells previously reported to have had high arsenic concentrations; 7 wells were located near other wells reported to have high concentrations of arsenic, and thc remaining 5 wells were located in areas where detectable concentrations of arsenic were suspected. Arsenic concentratioos near 10 parts per billion were detected at only 2 of the 19 wells sampled; arsenic concentrations in samples from the remaining 17 wells were reported as less than the USGS Central Laboratory reporting limits of 2 or 4 parts per billion. On the basis of limited sampling data available for this study, the concentrations of arsenic above drinking-water standards (10 parts per billion) do not appear to indicate a County-wide problem with regards to arsenic concentrations in groundwater. :igure 5-143.

This study concluded that a bedrock soume of arsenic is unlikely because the depth to bedrock in thc area of thc 19 wells sampled in 2002 ranges from about 600 to 1,700 feet below sca level, and most of these wells arc screened far above thc bedrock. Other naturally occurring rock sources of arsenic arc unlikely because most wells are screened in deposits of reworked fiuviodeltaic sediments and outwash, where most reactive minerals have been removed by geochemical processes. Industrial sources are unlikely because past and current land-use practices tend toward residential, farming, and open space. The most likely sources of arsenic in SC is from the geochemical reactions involving arsenic-bearing minerals within the unconsolidated deposits, and agricultural products (Cartwright, 2004). Salt Water Intrusion Freshwater aquifers along the Atlantic coast of the United States are 'vulnerable to the intmsion of saltwater from saline waters that bound the aquifers along their seaward margins. Incidences of saltwater intrusion have been documented along thc Atlantic coast for more than 100 years. The degree of saltwater intrusion along the coast varies widely and is affected by the hydrogeologic setting, history of ground-water development, and sources of saline water within a particular area.

Because freshwater is lighter than saltwater, fresh groundwater forms a barrier to saltwater 2000 Hazard Mitigation Plan - Suffolk County, New York. 5.4.6~i4 DRAFT - September 2007 SECTION 5.4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION flow, lying between thc land surface and deeper infiltrating saltwater. However, excessive removal of freshwater from tbc aquifer pulls thc saltwater farther inland and closer to the surface, where it can find its way into wells. Long Island pumps (discharges) more water from thc aquifers than they can naturally recharge. If this is done for a long period of time, the aquifer shrinks and is replaced by salt water (Bcnnington, Date Unknown). In many locations throughout Long Island, water supply wells have been shut down or abandoned as a result of salt water intrusion.. Currently, over 138 billion gallons of groundwater is pumped each year from beneath Nassau and Suffolk Counties. In coastal areas, as water is drawn up for use, less groundwater is available to be discharged into the estuaries (CCFE, Date Unknown). Areas were salt water intrusion have been specifically documented in SC include, but arc not limited to the following: · The North Shore of Long Island, New York, is characterized by numerous, bays and inlets separated by peninsulas that jut out into the Long Island Sound. These peninsulas, often called "necks", are surrounded on three sides by salt water, and have always been considered vulnerable to salt water intrusion of the fresh water aquifers that serve as their only supply of water (Maimone, 2001 ). · According to the USEPA, the North Fork of SC has experienced intrusion due to its highly consumptive use, mainly because of agricultural use (USEPA, 2007). According to the New York Times in 198'1, Ms. Betty Schloss of Southold Township indicated that "saltwater intrusion in private wells along Cedar Beach and in surrounding private communities such as Paradise Point, where she lives, was common" (NY. Times-Rather, 1981). According to SC officials, saltwater intrusion into the lens-like and shallow North Fork groundwater supply has reached critical proportions along both the Long Island Sound and Peconic Bay shorelines (NY Times-Ra. ther, 1981). · While the state of knowledge pertaining to local barrier island hydrogeology is limited, the close proximity of the aquifers underlying Fire Island National Seashore (FIIS) (which is located along Fire Island in SC) to the saltwater interface indicates that barrier islands may be particularly sensitive to saltwater intrusion which may, in mm, be influenced by periodic drought, groundwater pumping rates, and reduced infiltration, brought about by development in the surface recharge zone (USD1, 1992). · The problem of "saltwater upconing" (the upward movement of the saltwater - freshwater interface due to well pumping) is common among private wells in many coastal areas of the South Fork due to the thin layer of fresh groundwater in those locations. It is a major problem for private and public wells in the Montauk ~.rea, and has also been experienced at two deep public wells (Long Springs Road in Southampton and Oak View Highway in East Hampton) which are pumping from the Magothy aquifer (Group for the South Fork, 2007). Assessment of the extent or severity of groundwater contamination is difficult to determine, due to such Ihctors as limited and inconsistent access to the water (usually dependent on wells and springs); the polcmial for bias in existing data (if originally collected to explore a particular water quality problem); incomplete information about the wells and inconsistent methods of sampling and analysis (Moody, I t}96}. Additionally, severity can depend on a combination of the following parameters: concentration, persislcnce, and toxicity of the contaminants; the number of people affected if the contaminated aquifer is a suurcc of drinking water; and the percentage of the available groundwater (both locally and regionally) all~.'ctcd by such contamination. Interwoven with each of these factors would be the economic cost of finding an alternative source of water if thc contamination renders the groundwater unfit for its previous DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.6-15 DRAFT- September 2007 SECTION 5.4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION or future uses or if trcatment of the water before use is not possible. Many of the data required for these methods of assessing severity of contalnination ill quantitative terms are not available (Alcwinc, ct. al., 1984) Previous Occurrences and Losses Due to natural and/or manmadc groundwater contalnination being an ongoing issuc affecting Long Island's population directly or indirectly, former occurrences and losses/impacts itl association with specific natural contamination incidences within SC are difficult to quantify. The primary impact or loss associated with natural groundwater contamination is that the groundwater source becomes no longer available for any type of use. Once pollutants enter an aquifer, the environmental damage can be severe and long-lasting, partly because of the very long time needed to flush pollutants out of the aquifer. Probability of Future Events Groundwater quality will naturally continue to be disrupted from a variety of natural and human factors. In reference to future salt water intrusion, in recent years, water use/pumpage in SC appears to have exceeded the anticipated amount projected by the SCWA. In 2002, the SCWA reported a 45% increase in water use over the previous 10 years. This is more than double the increase projected in the SC comprehensive management plan at that time. An increase in groundwater consumption is one factor that can impact the equilibrium of fresh water and fresh groundwater, causing the freshwater-groundwater interface to move inland and exacerbate the problem of salt water intrusion. As more people develop and reside within SC's coastal communities, it is anticipated that water demands will continue to increase, creating a high probability of occurrence of salt water intrusion in SC. Earlier in this section, the identified hazards of concern for Suffolk County were ranked. The probability of occurrence, or likelihood of the event, is one parameter used in this ranking process. Based on historical records and input from the Planning Committee, the probability of occurrence for natural groundwater contamination events in the County is considered frequent [hazard event that occurs more frequently than once in 10 years (>10-~/yr)]. VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. For natural groundwater contamination, all of SC has been identified as the hazard area. Therefore, all assets, particularly the County's population, as described in the County Profile section, are vulnerable to this hazard. The following text evaluates and estimates the potential impact of severe storms on SC including: · Overview of vulnerability · Data and methodology used for the evaluation · Impact, including: (1) impact on life, safety and health of county residents, (2) general building stock, (3) critical facilities, and (4) economy · Further data collections that will assist understanding of this hazard over time · Overall vulnerability conclusion DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.6-16 DRAFT- September 2007 SECTION 5.4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION Overview of Vulnerability Natural contamination to Long Island's groundwater system, a federally-designated "sole source" aquifer, is a significant concern. This aquifer supplies drinking water to al} public and private water supply systems in SC. Additionally, this natural resource is used for recreation, industry and to support the agricultural community. Estimated losses arc difficult to quantify, however natural groundwater contamination will severely impact SC's population and economy. Data and Methodology Due to a lack of historic loss information, a qualitative assessment was conducted to evaluate the assets exposed to this hazard and the potential impacts associated with this hazard. Impact on Life, Health and Safety. · Essentially all of Suffolk County's residents obtain their drinking water from Long Island's sole source aquifer, whether supplied from public or private systems. Compromised groundwater quality could impact the entire County's population. According to the U.S. Census, the 2006 estimated population for SC is 1,469,715 people; approximately 1.2 million are on public water and more than 200,000 people are on private wells (U.S. Census, 2007; SC Department of Health Services, accessed online 2007). In general, private well owners/users are more vulnerable to natural groundwater contamination. USEPA regulates public water system and sets standards for contaminants in drinking water that may pose health risks. However, USEPA does not have the authority to regulate private drinking water wells. Private well ' water quality testing and water treatment is the responsibility of the well owner. In general, private well water quality is not tested as frequently as required by public water suppliers. Additionally, areas that rely on private wells for drinking water often use septic systems for sanitary waste water disposal, which may be another source of contamination. The SC Department of Health Services operates an extensive water testing program to help residents with private wells determine the quality of their drinking and suggest possible remedies if contaminants are detected (SC Department of Health Services, accessed online 2007). Proper water testing, well construction and continued maintenance are keys to the safety of private water supply. People who drink contaminated water may, immediately or over time, suffer from a variety of health problems depending upon the type of contamination. Depending upon the contaminant of concern, infants, young children and individuals with compromised immune systems may be more susceptible to illnesses from contaminated groundwater. It is difficult to measure and quantify the health costs that might be incurred due to natural groundwater contamination. Impact on General Building Stock and Critical Facilities No structures are anticipated to be directly affected by natural groundwater contamination. Impact on Economy Groundwater contamination's impact on the economy and estimated dollar losses are difficult to measure. Where groundwater becomes polluted, property values can drop and land may become unsellable. The price to remediate contaminated groundwater can be expensive and tax-payers may be burdened with this DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.6-17 DRAFT- September 2007 SECTION 5.4.6: RISK ASSESSMENT - NATURAL GROUNDWATER CONTAMINATION cost. Clean-up costs depend on many factors, including thc type of contaminant, its concentrations and extent. In many cases, the tull cost ofremediation is not realized, even after years have passed. Increased demand for bottled watcr may result in shortages and a higher cost for this resource. Industries that rely on water for business may also be impacted (e.g., agriculture). Additional Data and Next Steps Obtaining historic costs incurred to treat contaminated groundwater to mcct state and federal quality standards may help with modeling future losses, given a margin of uncertainty. Population growth, especially in SC's coastal communities, and demands on the Long Island Aquifer System should continue to be monitored to prevent over-pumping and exacerbating the problem of saltwater intrusion. Additional studies can also be conducted to delineate and continuously monitor the current extent of saltwater intrusion in SC. Overall Vulnerability. Assessment Natural groundwater contamination can significantly impact the County's population and economy. Thc overall bazard ranking determined for this Plan for the natural groundwater contamination hazard is medimm with a low impact on the economy. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.6-18 DRAFT- September 2007 SECTION 5,4.7: RISK ASSESSMENT - INFESTATION 5.4.7 INFESTATION This section provides a profile and vulnerability assessment for the infestation hazard. IIAZARI) PROFILE This section provides profile information including description, location and extent, previous occurrences and losses and the probability of future occurrences. Description An infestation is the presence of a large number of pest organisms in an area or field, on the surface of a host or anything that might contact a host, or in the soil. Infestations results when an area is inhabited or overrun by these pest organisms, in numbers or quantities large enough to be harmful, threatening, or obnoxious to native plants, animal species and/or human populations. A pest is defined as any organism (e.g., invertebrates/insects, mammals, birds, pathogens/parasites, fungi, nonnative species) judged as a threat to other living species in its surrounding environment. Most pests either compete with humans or other animals and plants for natural resources or transmit diseases to humans, their crops, or their livestock. A host is an animal or plant on which, or in which, a pest lives. Human populations are generally impacted by insect or animal infestations (e.g., mosquitoes, deer ticks, rabies-carrying animals/bird) which can result in human health impacts such as illnesses, disease and/or deaths, and can lead to potential epidemics or endemics if not maintained or controlled. However, infestations also occur from the introduction of non-native species (invasive species) that may not necessarily impact human health, but that create a nuisance or agricultural hardships by destroying crops and defoliating populations of native plant and tree species or entire ecological communities or plantations. In such a case, areas may become quarantined or affected species may have to be destroyed or cut down to prevent further spread of the pest organism. NYS has been impacted by various past and present disease-carrying insect infestations, including (1) high populations of mosquitoes (increasing the risk of West Nile Vires (WNV) and other diseases in animals and humans) and (2) high populations of deer ticks (increasing the risk of Lyme disease amongst animals and humans). In fact, the NYS Department of Health (NYS DOH) indicated that NYS has the highest number of reported (confirmed) cases of Lyme Disease in the U.S. (NYS DOH - Wadsworth Center, 2006). According to the NYS Department of Environmental Conservation (NYS DEC), exotic or nonnative pests that are an ongoing problem throughout NYS include, but are not limited to, the Asian Longhomed Beetle (Anoplophora glabripennis) (ALB), European Common Pine Shoot Beetle, European Gypsy Moth, Orange-Striped Oakwonn, and the Hemlock Woolly Adelgid. SC has expressed concern regarding the infestation of three primary disease-carrying or destructive pests that exist throughout the county, including mosquitoes, deer ticks and the ALB. Although many other types of infestations have occurred throughout the County, their impacts were temporary, relatively minor and/or limited information was found on their impacts; therefore, further details or assessments of those types of infestations are not deemed necessary for this HMP. Due to the large presence of mosquitoes, ticks and ALB populations, these three primary pests are the main focus for this hazard profile and are discussed below: West Nile Virus (WNV) has emerged in recent years in temperate regions of Europe and North America, presenting a threat to human and animal health. It first appeared in the Western hemisphere in 1999 in Queens, NY when it killed four people and quickly spread through North America. By 2003, all 50 states warned of an outbreak from any of the 30 mosquito species known to carry the WNV. WNV can infect at DMA 2000 H~zard Mitigation Plan - Suffolk Co~ntyl New York DRAFT- September 2007 5.417-1 SECTION 5.4.7: RISK ASSESSMENT - INFESTATION least 48 species of mosquitoes, over 250 species of birds, and at least 18 species of mammals, including humans. WNV is a member of the Flavivirus family, and is transmitted through infected mosquitoes. As a risk to humans, WNV is a mosquito-borne virus that can cause encephalitis (inflammation of the brain) or meningitis (inflammation of the lining of the brain and spinal cord). The virus is spread to humans by the bite of an infected mosquito. A mosquito becomes infected by biting a bird or mammal that carries the Since identification of WNV in NYS, confirmed human cases of the virus have been identified in many states and have resulted in deaths; however, less than one percent of those infected with WNV develop severe symptoms. Mild cases of a WNV infection may include a slight fever and head and body aches. Severe infections can include muscle weakness and may progress to encephalitis or meningitis. Symptoms usually occur three to 14 days 'after exposure. There is no specific treatment for the infection, other than to treat the symptoms and provide supportive care. Those who are at highest risk of becoming seriously ill from a WNV infection are persons over the age of 50. Healthy children and adults are at low risk for serious impacts from a WNV infection (NYS DOH, 2004). Lyme Disease is caused by the Lyme Disease Bacterium, Borrelia burgdorferi, which normally lives in mice, squirrels and other small animals. It is transmitted among these animals and to humans, through the bites of a certain species of ticks, particularly the deer tick (lxodes scapularis). Lyme Disease infections can cause symptoms affecting the skin, nervous system, heart, and/or joints of an individual. Lyme Disease can affect people of any age. People who spend time in grassy and wooded environments are at an increased risk of exposure. The chances of being bitten by a deer tick are greater during certain times of the year when ticks are most active. Young deer ticks, called nymphs, are active from mid-May to mid- August and are about the size of poppy seeds. Adult ticks, which are approximately the size of sesame seeds, are most active from March to mid-May and from mid-August to November. However, ticks can be active any time when the temperature is above freezing. Both nymphs and adults can transmit Lyme Disease. In tick prone areas, any contact with vegetation, even playing in the yard, can result in exposure to ticks (NYS DOH, 2006,). Since its discovery in the early 1980's, the U.S. Centers for Disease Control and Prevention (CDC) states that Lyme disease is the most prevalent tickobome illness in the U.S. It has been reported in 49 states and on four different continents. In 2000, approximately 16,000 cases were reported to the CDC. In 2002, there were 23,763 new cases reported in the U.S. Between 1996 and 2001 the number was leveled at about 17,000 new cases per year, but increased by nearly 7,000 cases in 2002. As of November 2006, over 72,000 cases have been reported for NYS to the NYS DOH since Lyme Disease became reportable in 1986 (NYS DOH, 2006). This increase in cases is due to many factors, including (but not limited to): · Increased surveillance and understanding of the disease system · The movement of people out of cities into more rural environments, which brings them into close proximity with the preferred habitat of the disease-carrying agents (e.g. ticks) · Forest fragmentation and increasing deer populations Dispersal of disease-carrying agents (e.g. ticks) into new, receptive habitats (Emerging Disease Issues, 2007) Asian Longhorned Beetles (Anoplophora glabripennis) (ALB) is an exotic pest, native to parts of Asia, threatening a wide variety of hardwood trees in North America, particularly in NYS, New Jersey and Chicago. The beetle is believed to have arrived in New York City in the 1980s, in wooden packing material used in cargo shipments from China. ~MA ~000 Hazard Miti~iion ~lan: Suffolk County, New YOrk DRAFT - September 2007 5.4.7-2 SECTION 5.4.7: RISK ASSESSMENT - INFESTATION These beetles have the ability to infest certain hardwood trees, eventually destroying them. They are a threat to public, private and commercial hardwood trees. When the eggs hatch, the immature beetles, which appear as big white worms, chew their way farther into the tree. When they mature, the full-grown beetles chew their way out of the tree. They typically attack a single tree but as the food source becomes exhausted, they will move to other nearby trees. The beetle life cycle leaves trees riddled with holes, oozing sap. The USDA believes this beetle can probably survive and reproduce in most sections of the country where suitable host trees exist. Table 5-40 presents a list of trees that may be attacked by the beetles: Acernegundo Acer plantanoindes Acer pseudop/atanus Acer rubrum Acer saccharinum Aescu/us hippocastanum Salixspp. U/mus americana Betula spp. Populus spp. Boxelder Norway maple Sycamore maple Red maple Silver maple Sugar maple Horsechestnut Willows American elm Bimhes Albizia julibrissin Celtis occidentalis Hackberry Fraxinus pennsylvanica Green ash Fraxinus americana White ash Pletanus acefifo/ia London plane Sorbus americana Source: (USDA Forest Service, 2007) Poplars Mimosa or Silktroe Mountain ash According to the Nature Conservancy, generally, ALB infestation has been restricted to urban street trees, but it is feared that populations will spread to wildlands and production forests. ALBs have a very wide host range and might cause significant die-offs of hardwood trees. Spreading populations threaten native woody species. ALB infestations of urban street and ornamental trees affects the aesthetic human environment. Larval tunneling weakens the structure of the tree so that limbs and in some cases entire trees may collapse, posing a danger to pedestrians and vehicles. Property values will also likely decrease in areas where ALB spreads and kills trees. ALBs have an affinity for hardwood trees, which poses a risk to forest and tree resource industries by reducing the quality of lumber, veneer and wood fiber (Morisawa, 2000). According to multiple sources, it has been indicated that the ALB has the potential to cause more damage than Dutch Elm Disease, Chestnut Blight, and Gypsy Moths combined, destroying millions of acres of DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.7-3 DRAFT - September 2007 SECTION 5.4.7: RISK ASSESSMENT - INFESTATION America's hardwoods, including national forests and backyard trees. The ALB has the potential to damage such industries as lumber, maple syrup, nursery, commercial fruit, and tourism accumulating over $41 billion in losses (Muruetagoiena, 2004). The government is rapidly trying to eradicate this species primarily because of two reasons: (1) Potential hnpact - If it becomes established in this country it could significantly impact our natural forest and urban environment. {2) Current Limited Infestation Size - Infestations are limited at this time and the federal government still believes ALB can be eliminated completely if action is taken now. Many steps have been taken to eliminate or eradicate the ALB, including: · Quarantines: Quarantines have been established around infested areas to prevent accidental spread of ALB by people. · Infested trees cut, chipped and burned: All infested trees are being removed, chipped in place, and burned. The stumps of infested trees are ground to below the soil level. All tree removal is done by certified tree care personnel to ensure that the process is completed properly.. · Insecticide treatments: Research is underway way to determine the effectiveness of certain insecticides such as Imidacloprid against ALB. Insecticidal treatments have begun in NYS and Chicago in hopes of preventing and containing 'infestations. · Extensive surveys: All host trees on public and private property located within an established distance from an infested area are surveyed by trained local, state, or federal personnel. Infested areas will be re-surveyed at least once per year for 3~5 years after the last beetle or infested tree is found. Location and Extent The presence of disease-carrying mosquitoes and ticks and the presence of nuisance ALBs have been reported throughout most of NYS and in SC for many years. Information regarding the location of these pests is further discussed below. West Nile Virus (WNIO WNV has been described in Africa, Europe, the Middle East, west and central Asia, Oceania (subtype Kunjin), and most recently, North America. Outbreaks of W3qV encephalitis in humans have occurred in Algeria in 1994, Romania in 1996-1997, the Czech Republic in 1997, the Democratic Republic of the Congo in 1998, Russia in 1999, the U.S. in 1999-2003, and Israel in 2000. Epizootics (an epidemic outbreak of disease in an animal population, often with the implication that it may extend to humans) of disease in horses occurred in Morocco in 1996, Italy in 1998, the U.S. in 1999-2001, and France in 2000, and in birds in Israel in 1997-2001 and in the U.S. in 1999-2002. In the U.S. since 1999, WNV human, bird, veterinary or mosquito activity have been reported from all states except Hawaii, Alaska, and Oregon (CDC, 2004). WNV has spread rapidly across North America (Figure 5-145), affecting thousands of birds, horses, and people since it was discovered in the Western Hemisphere. Since 1999, WNV has swept from the New York City region to almost all of the continental U.S., 7 Canadian provinces, and throughout Mexico and parts of the Caribbean.

WNV Activity From 1999 to 2002 in Eastern United States Wesl Nile Virus: Aclivil¥ Over Thne ia No,th America 1999 2000 2001 Confirmed WNV activity 2002 Source: (USGS, 2003) WNV has been present in humans, birds, mammals and within mosquito pools throughout SC since 1999. In November 2000, the Division of Public Health completed a WNV human seroprevalence survey ("serosurvey' or blood-sample survey) in the Town of Babylon. This consisted of random household cluster blood-sample surveys in several neighborhoods in the Town of Babylon to find out what percent of people in the area may have been exposed to WNV, and what puts people at risk for the infection. The survey was a major collaborative effort by representatives of the CDC, NYS DOH and the Suffolk County Department of Health Services (SCDHS). Blood specimens were collected from 836 resident volunteers in 703 randomized households within a 27 square mile area of Babylon, The blood was tested for WNV-anfibody at the NYS DOH laboratory. Confirmatory testing was completed at the CDC. This study confirmed the presence of WNV viral infection in people for the first time in SC (Health Services, 20O5). The SCDHS provided summary maps of WNV positive results in SC for 2000 and 2001 for birds, mosquito pools, mammals, and humans. The Towns of Babylon, Huntington, Islip and Smithtown had the most reported cases in 2000 (Figure 5-146) and the Towns of Islip, Brookhaven and Smithtown had the most reported cases in 2001 (Figure 5-147) (Health Services, 2005). Maps for 2003 through the present are not available at this time; however, if more current maps become available, they may be added to later versions of this HMP.

In the U.S., the highest incidence occurs in the Northeast, from Massachusetts to Maryland and the North-central states, especially Wisconsin and Minnesota. In 2002, more than 23,000 cases of Lyme disease were reported in the U.S., the highest number ever reported. This increase could be caused by an increase in human contact with infected ticks and enhanced reporting of cases. Twelve states reported an incidence of Lyme Disease that was higher than the national average in both 2001 and 2002: Connecticut, Delaware, Maine, Maryland, Massachusetts, Minnesota, New Hampshire, New Jersey, NYS, Pennsylvania, Rhode Island, and Wisconsin. These 12 states account for 95% of cases reported nationally (Todar, 2005). The CDC Division of Vector Borne Infectious Diseases (DVBID) indicated in 2006 that NYS was the state with the most confirmed Lyme disease cases from 1993 to 2005, totaling approximately 60,137 cases. Pennsylvania, Connecticut, and New Jersey followed (CDC, 2006). As of November 2006, over 72,000 cases have been reported for NYS to the NYS DOH since Lyme Disease became reportable in 1986 (NYS DOH, 2006). This disease has become endemic in Suffolk, Nassau, Westchester, Rockland, Putnam, Orange, Ulster, Dutchess and Albany counties. The deer tick has been found in 42 counties within NYS. The deer tick does not appear to be a resident of New York City, although the American dog tick (Dermacentor variabilis), the vector of Rocky Mountain spotted fever, does occur in coastal areas of New York City and is common on Long Island and in downstate counties. In infested areas, the deer tick is common wherever deer and woodland mice frequent. White-tailed deer thrive where suburban lawns adjoin woodland or open fields. Open areas provide deer grazing areas, woods offer shelter and browse (food), and residential lawns provide ornamental plantings that serve as a food source. People are increasingly establishing their home sites in wooded areas. In so doing, they create a habitat that attracts deer, mice and ticks. On Long Island, ticks are often found in beach grass near seashores in addition to the above- mentioned areas (Cornell Cooperative Extension, 2003). A July 2006 Suffolk Life news article indicated that the U.S. Senator Chuck Schumer (D-NY) recently called for more research on the treatment and diagnosis of Lyme disease, due to its increasing prevalence, specifically on Long Island, NY. However, according to Stony Brook University Hospital doctors, it is not just Lyme disease that is caused by ticks, as these insects, also, are capable of causing several other serious illnesses (Centamore, 2006).

Currently Babesiosis, Ehrlichiosis, Lyme disease and Rocky Mountain Spotted Fever are reportable diseases and endemic to SC (Suffolk County Health Assessment, 2005). Asian Longhorned Beetle (ALB) Although it is believed that this beetle arrived in the U.S. between the 1980's and 1990's, the ALB was first discovered in McCarren Park of Greenpoint, Brooklyn on August 19, 1996 and soon after in Amityville, Long Island in September 1996. Since then, infestations were found in and around New York City, including on Long Island (Bayside, lslip), Manhattan, Queens and Flushing Park. At present, it has been found in several areas in New York City and Long Island, the Chicago area (the quarantine being lifted on July 12, 2006), New Jersey, and Toronto, Canada. Additionally, the USDA's Animal and Plant Health Inspection Service (APHIS) detected ALB in 26 warehouses and residential sites in 14 states. These detection led to actions that prevented the ALB from getting outdoors. According to the University of Vermont (UVM) Entomology Research Laboratory, a 2001 map was provided indicating the location of detected ALB infestations throughout the U.S (Figure 5-150).

Code of Federal Regulations (e-CFR), Title 7: Agriculture, PART 301--Domestic Quarantine Notices, have been developed by the USDA-APHIS for handling wood and planting trees in these ALB quarantine zones. The Nature Conservancy has indicated that if ALBs were to break out of the established quarantine areas and spread into upstate NYS and New England,.they could cause a devastating economic blow to the sugar maple, tourism, timber, and forest product industries. Over 1.5 billion trees are susceptible across New England (The Nature Conservancy, 2007). Figure 5-151 shows the 2003 Quarantine Boundaries throughout New York City and Long Island. Recently, the USDA indicated that all infested areas in NYS remain under regulation (quarantine) (APHIS, 2006).

This EM provided up to $5 million in federal funds to reimburse affected local governments at 75 percent federal share for the cost of emergency measures that were taken to save lives and einsure public health and safety. Estimated cases or losses for SC were not determined through FEMA (FEMA, 2007). However, as indicated by the NYS DOH, it was reported that 210 birds, 121 mosquito pools and 8 horses tested positive for WNV between January and December 2000 (NYS DOH, 2001). As previously stated, in November 2000, the Division of Public Health completed a WNV human serosurvey in Babylon. The survey was a major collaborative effort by representatives of the CDC, the NYS DOH and the SCDHS. Blood specimens were collected from 836 resident volunteer in 703 randomized households within a 27 square mile area of Babylon. The blood was tested for West Nile virus-antibody at the NYS DOH laboratory. Confirmatory testing was completed at the CDC. This study confirmed the presence of WNV viral infection in people for the first time in SC. According to the 2002 SCDHS Annual Report, for the fourth consecutive year, the presence of WNV was confirmed in SC. Extensive human, bird, horse and mosquito surveillance programs were again instituted with the reestablishment of the WNV hotline. Eight human cases with two fatalities from WNV disease occurred in 2002. A WNV hotline was operational, with the assistance of seasonal employees, from June through September, corresponding with mosquito activity. The hotline received over 3,600 calls regarding dead or ill bird sightings. A total of 180 birds from nine towns, mostly crows, tested positive for presence of the virus (Huntington 62; Babylon 10; Smithtown 22; Islip 35; Brookhaven 31; East Hampton 3; Riverhead 1; Southampton 12; Southold 4), which represents 13% of all the positive birds in NYS. Als6, there were 34 positive pools for WNV (Huntington 5, Babylon 3, Smithtown 5, lslip 6, Brookhaven 7, Riverhead 6, Southampton 1, East Hampton 1 ) (SCDHS, 2002). According to the USGS Disease Maps 2005 database, between June and September 2005, SC experienced the highest reported cases of mosquito WNV infections in NYS (Figure 5-155) with 76 cases, compared to 387 cases statewide. Figure 5-156 shows that SC also experienced the highest amount of dead bird WNV infections with 101 cases during this time period. Although not shown as a Figure, Long Island, NY experienced the highest amount of human WNV cases, with Nassau County experiencing 12 incidences and SC experiencing 9 between July and September 2005 USGS, 2006).

A SC sample was collected from the Blydenburgh County Park in Smithtown, by the CDC on July 17, 2007, and was later found to be positive. The County closed the park's campground indefinitely and activities in the park have been restricted to daylight hours (Holley, 2007). DM~ 2000 H~zar~ Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.7-15 SECTION 5.4.7: RISK ASSESSMENT - INFESTATION WNV data ranging from 2000 to 2007 was provided by the NYS DOH, for all counties of NYS, including SC (Table 5-42). This data indicates that approximately 1,026 live and dead bird species, 33 horses, 402 mosquito pools, and 30 humans tested positive for WNV within SC between 2000 and 2007, with 4 deaths occurring in 2002 and 2003. Most WNV incidences were reported in SC between 1999 and 2003. It is assumed that the decline from 2004 to the present is from the implementation of preventative measures, eflbrts made to raise public awareness, and through surveillance efforts to control the spread of WNV disease throughout the state. Measures could have included wearing proper attire when outside to avoid being bit, eliminating mosquito breeding areas, reducing areas of standing water, using insect repellants and educating the public on how to take precautions and avoid potential exposure.

Lyme Disease As of November 2006, over 72,000 cases have been reported for NYS to the NYS DOH since Lyme Disease became reportable in 1986 (NYS DOH, 2006). These statistics are the most recent for the NYS. According to the NYS DOH 2005 Communicable Disease Annual Report, SC experienced 542 reported cases of Lyme Disease in 2005, which was the 2"a highest amount of cases in NYS, following behind Dutchess County with 1,398 cases (NYS DOH, 2006). Updated 2006-2007 statistics for SC were not available in the materials reviewed to develop this plan.

DMA 2000 Hazard Mitigation Pi~n ~ ~U~oik 0un , New York DRAFT - September 2007 5.4.7-17 SECTION 5.4.7: RISK ASSESSMENT - INFESTATION Asian Longhorned Beetle (ALB) A brief ALB timeline of NYS Activities was provided by USDA Animal and Plant Health Inspection Service (APHIS) from 1996 to 2006 and the New York City Department of Parks and Recreation provided updated ALB info for 2007. August 19, 1996: ALB detected in the Greenpoint neighborhood of Brooklyn, NY. This was the first ALB detection in the U.S. · August 1996: ALB detected in Amityville on Long Island, NY a few weeks after the first detection· · February 10, 1999: ALB detected in the Bayside area of Queens County, NY. · September 1, 1999: ALB detected in the Islip area of Long Island, NY. · June 29, 2000: ALB detected in the Luther Gulick Playground in the Lower East Side area of Manhattan. · 2006: ALB detection in New York City: Manhattan, Queens and Brooklyn · 2007: Most recent ALB infestation areas were found in Queens and Staten Island (NYCDPR, 2007) ALBs have caused serious tree losses in both NYS and Chicago, IL, particularly in New York City. Since its initial discovery in NYS in 1996, tree destruction and removal has been the only method for controlling the spread of ALB infestation. According to Mark Buccowich of the USDA Forest Service on November 15, 2001, ALB infestations were responsible for the destruction of a combined 7,900 trees in the quarantined areas in NYS and Illinois between 1998 and 2001. As of 2005, the NY ALB Cooperative · Eradication Program repons that NYS agricultural officials removed and destroyed more than 7,190 trees in and around New York City and Long Island. However, this number of tree losses differs amongst various sources. Table 5-44 provides USDA data on the various areas of NYS that have been under quarantine, the date ALB were first found in that quarantine area, and the total number of infested trees found and removed in that area and cumulatively in NYS as of March 2006 (USDAFS, 2005). Table 5-44. New York ALB Detection and Tree Removal 2006 108 Cen I 2006 1,929 2006 27 N/A 6,041 Source: (USDA, 2006) Note: It is assumed that these numbers have fluctuated since 2006. According to Senator Hillary Clinton in April 2007, the ALB puts 35 percent of American urban trees at serious risk, at a combined replacement value of $669 billion. The threat is even greater in New York City, with 47 percent of its 5.2 million trees susceptible to ALB infestation (Clinton, 2007). DMA 2000 Hazard Mitigation Plan - Suffolk C0Untyl New York 5.4.7-18 DRAFT - September 2007 SECTION 5.4.7: RISK ASSESSMENT - INFESTATION Many more trees have had to be treated with insecticides to decrease beetle populations and prevent future tree loss. According to a May 2004 news article by the NY ALB Cooperative Eradication Program, the USDA APHIS indicated that approximately 69,000 trees susceptible to the ALB in NYS would have to be treated. Approximately 12,500 trees in Manhattan; 23,000 in Brooklyn; 24,500 in Queens and 9~000 on Long Island were to be treated (APHIS, 2004). More recently, a March 28, 2005 NY ALB Cooperative Eradication Program Quarterly Report, indicated that the number of trees to be treated increased to approximately 78,200 trees susceptible to the ALB in NYS. APH1S was to treat trees in portions of the 132 square miles of the quarantine area in NYS. Approximately 18,400 trees in Manhattan; 35,500 in Brooklyn; 19,400 in Queens and 4,900 on Long lsland were to be treated. Current status of these trees is not made available (USDA, 2005). The replanting of trees has been an ongoing effort, to make up for the loss of trees that have been removed or destroyed from the ALB infestations. Since 1996, more than 5,000 trees have been planted on Long Island and in New York City by Trees New York, the New York City Depaitment of Parks & Recreation and the Town of Oyster Bay, in cooperation with the NYS DEC and the USDA Forest Service. As part of this ongoing effort, another 150 street trees were planted on public land in the Towns of Babylon, Oyster Bay and Islip (APHIS, 2004). Actual monetary losses associated with the destruction, removal and replanting of trees has not been clearly identified for NYS or SC through review of available documentation. Probability of Future Events Based on historical documentation, increased incidences of infestation throughout Long Island and the overall impact of changing climate trends, it is estimated that SC and all its jurisdictions will continue to experience infestation events that may induce secondary hazards and health threats to the County population if infestations are not prevented, controlled or eradicated effectively. The Planning Committee views this as a "frequent" hazard of concern (hazard event that occurs more frequently than once in 10 years (>10-1/yr) (see Table 5-4 in Section 5.3). It ~st Nile Virus (WNV) WNV. never seen on this continent until eight years ago, has infected more than 21,000 people in the U.S. and Canada and killed more than 800 (Struck, 2006). Based on available data, it is expected that many more incidences will occur in the future throughout the U.S., including NYS. According to a SC Community Health Assessment, which was prepared as a projection for 2005 through 2tH0. the potential threat of mosquito-borne disease in SC is real and growing. When this assessment was prepared, SCDHS records showed that during the past 10 years, 7 public health threats were declared in SC during the following years: 1994, 1996, 1999, 2000, 2001, 2001, and 2003. All 7 public health threats xx crc declared because of detection of mosquito-borne human diseases or pathogens, including Eastern Eqaine Encephalitis virus (EEL), malaria, and WNV disease. During these years, the following actual human diseases and deaths from locally acquired mosquito-borne disease were documented in SC: (1) malaria case in 1999 in two young children, (2) WNV infections in 2000, (3) I WNV meningitis case in 2001. (4) 8 WNV meningitis/encephalitis cases in 2002, which included 2 human deaths, and (5) 10 \VNV meningitis or encephalitis cases in 2003, including 2 human deaths. Of the 19 WNV human meningitis or encephalitis cases in SC between 2003 and 2005, 4 people died and 16 suffered from neurological complications. This is prima facie evidence of a continuous and growing threat to the public hcahh. All of the critical components necessary to sustain the threat of mosquito-borne disease in SC have been clearly documented and appear to be occurring more frequently (i.e., the simultaneous presence of pathogenic organisms, mosquito species (vectors) capable of transmitting disease, and a susceptible DM~ ~000 Hazard Mitigation Plan - suffolk C°un~i N~ ~ork DRAFT- September 2007 5.4.7-19 sEcTIoN 5.4.7: RISK ASSESSMENT - INFESTATION population) (Suffolk County Health Assessment, 2005l. Therefore, based on all available information and available data regarding mosquitu populations, it is anticipated that WNV infections will continue to be a threat to SC. LymesDisease Disease-carrying ticks will continue to inhabit the northeast, including SC. creating an increase in Lyme Disease and other types of infections amongst the county population if not controlled or prevented. Ecological conditions favorable to Lyme disease, the steady increase in the number of cases, and the challenge of prevention predict that Lyme disease will be a continuing public health concern. Personal protection measures, including protective clothing, repellents or acaricides, tick checks, and landscape modifications in or near residential areas, may be helpful. However, these measures are difficult to perform regularly throughout the summer. Attempts to control the infection on a larger scale by the eradication of deer or widespread use of acaricides, which may be effective, have had limited public acceptance. New methods of tick control, including host-targeted acaricides against rodents and deer, are being developed and may provide help in the future (Steere, Coburn, and Glickstein, 2004) Currently and in the future, control of Lyme disease will depend primarily on public and physician education about personal protection measures, signs and symptoms of the disease, and appropriate antibiotic therapy. Based on available information and the ongoing trends of disease-carrying tick populations, it is anticipated that Lyme disease infections will continue to be a threat to SC. Asian Longhorned Beetle 64LB) The spread of ALB to other tree populations should be preventable if USDA quarantine restrictions are followed with the ongoing monitoring of area trees for rapid detection of beetle infestations. According to the USDA APHIS, surveys, regulatory measures and control that the ALB problem can and should be eradicated. However, the USDA also indicates that if this beetle continues to spread, potential damage is significant throughout the U.S., including NYS. The Role of Climate Change on Infestation Climate change, if it occurs at the level projected by current global circulation models and current resources, may have direct and indirect effects on disease-carrying and nuisance pest infestations and the spread of infectious diseases, especially those transmitted by poikilothermic arthropods such as mosquitoes and ticks, and a variety of other insects (Colwell et. al., 1998). Insects are cold-blooded organisms, where the temperature of their bodies is approximately the same as that of the environment. Therefore, temperature is probably the single most important environmental factor influencing insect behavior, distribution, development, survival, and reproduction. Since insects have proven to be highly adaptable to temperature, they can cope with a variety of environmental changes, including relatively recent changes in the world's climate, it appears that insect species that adapt to warmer climates also will increase their maximum rates of population growth because they have higher metabolic rates and reproduce more frequently, which is likely to have widespread effects on agriculture, public health and conservation (Stricherz, 2006). Many health experts indicate that climate changes (e.g., global warming), with an accompanying rise in floods and droughts, is fueling the spread of infestations and epidemics (e.g., WNV, Malaria, Lyme Disease). Mosquitoes, ticks, and other nuisance and disease-carrying organisms (e.g., ALB) are surviving warmer winters and expanding their range, bringing increased health threats, creating economic hardships and disrupting agriculture and natural ecological communities as they spread (Struck, 2006). According to the USDA Forest Service, climate directly increases insect populations as longer, wanner, growing seasons permit more annual insect generations, and permit insects to expand their geographic distribution DMA 2000 Hazard Mi[igaiion ~1~ ~ ~0ff01k c0untyl Ne~ York DRAFT- September 2007 5.4.7-20 SECTION 5.4.7: RISK ASSESSMENT - INFESTATION upward in elevation and far north of their historic ranges. Climate indirectly increases insect population densities by increasing temperature and drought stress on trees, reducing trees' ability to resist insect attacks, much like the attacks of the ALB throughout the northeast (USDA, 2007). Although some climate change temperature effects might tend to depress insect populations, most researchers seem to agree that warmer temperatures in temperate climates will result in more types and higher populations of insects (Petzoldt & Seaman, Date Unknown). As historic and current documentation indicates, mosquitoes and ticks and various other pest organisms flourish throughout NYS. If conditions become warmer and wetter, as predicted, mosquito and tick populations could increase throughout the state, thereby increasing the risk of infestation and transmission of disease to humans and wildlife populations (USEPA, 1997). However, continuous reseamh of climate change on insect populations and distribution and the implementation of public health measures, surveillance, and prevention and control measures will play a large role in determining the future existence or extent of infestations and/or infections within a given region. The recent outbreaks of WNV across the U.S. (during the 2002 drought) are a preview of how a changing climate could threaten human health. Many mosquito-borne diseases are known to be sensitive to climatic conditions, including increased temperature, among other factors. Now there are indications that climate variability, not just higher temperatures, can also contribute to increased disease. While other factors come into play, WNV outbreaks have been related to a combination of heat and drought followed by heavy downpours. And that kind of weather pattern, according to The Intergovernmental Panel on Climate Change (IPCC), is likely to occur more often with global wanning. When WNV first emerged in the U.S., conditions were ideal for an outbreak. The U.S. had never had a documented case of WNV before it was introduced from overseas in 1999. That y~ar, New York City experienced its driest and hottest spring and summer in a century. Stagnant and polluted pools of water throughout the city became the perfect breeding grounds for the mosquito vector, Culex pipiens. Mosquitoes fed on birds, drawn to the shrinking pools of water, infecting them with WNV and killing many of them in the process. Uninfected birds flew to wetter habitats as the drought deepened and mosquitoes within the city then had to mm to humans for their next blood meals. The heavy downpours that eventually broke the drought that summer created new breeding sites. The mosquito populations soared and the virus spread. At the end of the epidemic, more than 8,000 people had been infected, 62 had fallen ill to the virus, and seven died (Despommier & Bloomfield 2002). Most scientists agree that global climate change will influence infestations and infectious vector-borne disease transmission dynamics; however, the extent and/or severity of the influence is uncertain (Colwell et. al., 1998). Scientists have warned for more than a decade that climate change would broaden the range of insect distribution, infestation and transmission of many diseases. However, the spread of infestation and disease is affected by many uncertainties, including unforeseen resistance to various control measures (e.g., insecticides, pesticides, antibiotics in humans), failures of public health systems, population movement, yearly climate fluctuations and natural insect adaptations to a changing climate. For that reason, some scientists have been cautious about the link between infestations, disease and glObal warming. Although many uncertainties do exist, the preponderance of evidence indicates that there will be an overall increase in the number of outbreaks of a wider variety of insects and pathogens as a result of climate change throughout the U.S. Therefore, NYS, including SC, will most likely be subject to the on- going presence of these disease-carrying and nuisance pest species in the future as a result of climate change (Petzoldt & Seaman 2006). DMA 2000 FI"~'~;~ Miii~aii0n Plan - Suffolk countyl New York DRAFT- September 2007 5.4.7-21 SECTION 5.4.7: RISK ASSESSMENT - INFESTATION VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. For infestation, SC has been identified as the hazard area. Therefore, all assets in SC, as described in the County Profile section, are vulnerable to infestation. The ~'ollowing text evaluates and estimates the potential impact of infestation on SC including: · Overview of vulnerability · Data and methodology used for the evaluation · Impact, including: ( 1 ) impact on life, safety and health of county residents, (2) general building stock, (3) critical facilities, and (43 economy · Further data collections that will assist unddrstanding of this hazard over time · Overall vulnerability conclusion Overview of Vulnerability Infestation is a significant concern to SC, mainly due to its impact on public health and natural resources. Estimated losses are difficult to quantify; however infestation can impact SC's population and economy. According to the Long Island Chapter of The Nature Conservancy, infestation also has major impacts on the terrestrial ecosystems of SC and threatens ecological diversity on Long Island. Additionally, direct impacts of infestation have cascading indirect impacts. As vegetation dies or becomes stressed/weakened by pests such as the ALB, there is an increase in available fuel and increase in high intensity wildfires. As species composition changes due to infestation outbreaks, whole fire regimes can shift. Physical stresses on trees may also affect how street trees respond to physical stresses caused by other natural hazards such as hurricanes, drought and ice storms (Kurtz, 2007). Data and Methodology Due to a lack of quantifiable loss information, a qualitative assessment was conducted to evaluate the assets exposed to this hazard and the potential impacts associated with this hazard. Impact on Life, Health and Safety All of SC's residents are vulnerable to infestation. According to the 2000 U.S. Census, SC had a population of 1,419,369 people. The U.S. Census 2006 population estimate for SC is 1,469,715. Persons over the age of 50 are considered most susceptible of becoming seriously ill from a WNV infection. According to the 2000 U.S. Census, there are 497,927 people over the age of 45 in SC (the U.S. Census does not specify the number of people over the age of 50) (U.S. Census, 2000). Temporal changes affect the total population vulnerable to this hazard. Certain species that transmit diseases (i.e., deer ticks and Lyme Disease and mosquitoes and WNV) are most active during the spring, summer and early fall months, when SC population is at its peak. The SC Planning Department estimates that the eastern SC population (Towns of Riverhead, Southold, Shelter Island, Southampton, and East Hampton) more than doubles during the summer. This population increase coincides with active tick and mosquito periods. Also, summer visitors are likely to access recreational and coastal areas that are likely inhabitants of pests. This presents a potential risk of increased exposure and impacts. DMA 2000 i-la~rd Mitigation Pi'~n 2 §~ffoIk County, New Yo;k 5.4.7-22 DRAFT- September 2007 SECTION 5,4.7: RISK ASSESSMENT - INFESTATION Direct impacts of infestation (e.g., species changes in the terrestrial system and increase in stressed or dead vegetation) have cascading indirect impacts (e.g., increase in available fuel for wildfire). Increased fuel and changes in whole fire regimes impacts the life and safety of SC residents. Impact on General Building Stock No structures are anticipated to be directly affected by infestation. Impact on Critical Facilities No structures are anticipated to be directly affected by infestation. Impact on Economy lnfestation's impact on the economy and estimated dollar losses are difficult to measure and quantify. Costs associated with the activities and programs implemented to conduct surveillance and address infestation have not been quantified in available documentation. Instead, activities and programs implemented by the County to address this hazard are described below, all of which could impact the local economy. The SC Department of Public Works (DPW), Division of Vector Control, is responsible for controlling mosquito infestations. To control mosquito infestation, Vector Control employs an integrated control program that concentrates on stopping mosquitoes at the larval stage. This includes water management (i.e., draining standing water in ditches and marshes without harming the vegetation and environment), biological control (i.e., utilizing fish and other predators to eat mosquito larvae), and utilizing bacterial pesticides and insect growth regulators to kill larvae and adult mosquitoes (Suffolk County Government, Date Unknown). The SCDHS and SC Parks continuously prepare education materials and align with community partners to educate the public on Lyme Disease. As part of this commitment to public awareness, the month of May has been designated by SC as Lyme Disease Awareness Month. The SCDHS, Bureau of Preventative Services conducts arthropod-borne diseases surveillance to determine the presence of various species and prevalence of these pathogens in our arthropod population and investigate health threats of arthropod-borne diseases to SC residents (Suffolk County Government, Date Unknown). Steps taken m address and eradicate ALB may be costly to local governments and impact the economy. As stated earlier, these steps include: (1) quarantine infested areas; (2) cut, chip and burn infested trees; (3) apply of insecticide treatments to decrease beetle populations and prevent future tree loss; and (4) survey impacted areas. Additional costly actions to address ALB include the replanting of trees to make up for the trees removed or destroyed. Lastly, the clean-up and removal of tree debris as a result of severe weather may be prolonged and more costly due to the need to adhere to quarantine areas. Additional Data and Next Steps Obtaining historic costs incurred to conduct surveillance, prevent, treat and eradicate infestation may help with quantifying losses, given a margin of uncertainty. Overall Vulnerability Assessment Infestation can significantly impact the County's population and economy. The overall hazard ranking determined for this Plan for the infestation hazard is "medium" (Tables 5-6 and 5-7). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 514.7-23 SECTION 5.4.8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING 5.4.8 SHALLOW GROUNDWATER FLOODING This section provides a profile and vulnerability assessment for the shallow groundwater flooding hazard. HAZARD PROFILE This section provides profile information including description, location and extent, previous occurrences and losses, and the probability of future occurrences. Description As detailed in the flood hazard profile, a flood is a general and temporary condition of partial or complete inundation of normally dry land areas, resulting from: · Overflow of inland or tidal waters · Unusual and rapid accumulation ofrunoffor surface waters · Mudslides/mudflows caused by accumulation of water · A situation in which rainfall is so intense and severe and runoff so rapid that is precludes recording and relating it to stream stages and other information in time to forecast a flood condition (FEMA, 2004; NYS Disaster Preparedness Commission, 2004). According to the Federal Interagency Floodplain Management Task Force, flooding in the United States can be separated into several types (L.R. Johnson Associated, FIA-18, 1992), including "high groundwater levels." Per the Federal Emergency Management Agency's (FEMA's) "Multi-Hazard Identification and Risk Assessment - The Cornerstone of the National Mitigation Strategy (1997), "high groundwater levels may be of concera and can cause problems even when there is no surface flooding. Basements are susceptible to high groundwater levels. Seasonally high groundwater is common in many areas, while in others high groundwater occurs only after long periods of above-average precipitation." SC has experienced shallow groundwater flooding hazard impacts in the past. This profile addresses high (shallow) grotmdwater levels throughout the County that have resulted in persistent structural flooding losses, underscored by serious ongoing problems in the areas around Lake Ronkonkoma and the Northeast Branch of the Nissequogue River. For the purposes of this planning effort, the shallow groundwater flooding hazard has been defined as the condition of a sufficiently shallow groundwater table (saturated zone) either cyclically or persistently above the level of subsurface structures resulting in negative irnpacts. Impacts to subsurface structures include groundwater seepage into basements and septic system failures. In some cases, shallow groundwater breaches the land surface and floods low- lying roadways, as covered more generally under the "flooding" hazard in this Plan. The hazard definition for this planning effort does not include groundwater seepage as a result of heavy precipitation events where the actual groundwater table {saturated zone) does not impinge on subsurface structures. [;)MX ~006 Iq~ Mitigation Plan - Suffolk co~niyl N~ ~ork gi~iS:~ Draft- September 2007 SECTION 5,4.8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING Location and Extenl Shallow groundwater conditions are found throughout the County, typically in low-lying areas such as along the coast, near surface water bodies (including wetlands, marshes and bogs), and along ancestral drainage courses. Soil permeability often exacerbates shallow groundwater problems in such areas, as in morainal areas that contain glacial till (as opposed to areas with higher permeability geologies such as outwash deposits). Further, the presence and severity of shallow groundwater conditions is a function of long-term precipitation trends in the area. The fact that shallow groundwater tables are found in low-lying areas and in proximity to surface water bodies is well recognized and understood. As detailed in the "Hydrology and Hydrogeology" section of the SC profile (Section 4), the upper glacial aquifer is the uppermost unit in Long Island's groundwater reservoir and contains the water table throughout the majority of the island. The upper surface of the upper glacial aquifer forms the present day land surface of most of Long Island. While in parts of Long Island, the upper glacial aquifer overlies geologies with high hydra, ulic conductivities, some parts of the' aquifer overlay areas of limited conductivity (Gardiners clay along the much of the southern shore, and subcrops of the Raritan clay confining unit along paris of the northern shore). As stated in U.S. Geological Survey (USGS) Water-Resources Investigations Report (WRIR) 01-4165, the upper glacial aquifer consists of till, outwash deposits, and three major glaciolacustrine and marine clay units. These include the "Smithtown clay' in north central SC, the "Manorville clay" in east-central SC, and "the "20-foot clay" in southwestern SC. These minor clay units impede the downward movement of water, and each one creates locally elevated water tables (USGS, WRIR 01-4165, 2002). Precipitation is the sole source of all naturally occurring fresh groundwater on Lo/~g Island, and seasonal or long-term fluctuations in precipitation are reflected by the water levels in all aquifers (USGS, WRIR 01-4165, 2002). The general trends in the rise and fall of the water table follow general trends in precipitation (H2M, 1980). Long-term surface water data collection by the USGS in most parts of the island began in the 1930s and 1940s (USGS, WRIR 01-4165, 2002). This report clearly demonstrates the correlation between groundwater levels and long-term precipitation trends, as determined through measurements collected at the precipitation-monitoring stations and groundwater monitoring wells shown on Figure 5-158.

DMA 2000 Hazard Mitigation Plan ' SuffOlk County, New York DRAFT - September 2007 5.4.8-4 SECTION 5.4.8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING With respect to the current shallow groundwater flooding problems plaguing the Smithtown area, New York State Department of Enviromnental Conservation (NYS DEC) Regional Director Peter Scully indicated the groundwater table is the highest it has been in 34 years, surging after heavy rains in October, 2005. "You saw a big jump in [groundwater levels in] all areas of the island," said Ronald Busciolano, Supervisory Hydrologist and Data Chief at the USGS - Coram office. More than a year later, the water table around Lake Ronkonkoma remains near record levels, Busciolano said. On a cul-de-sac just north of the lake~ wetlands continue to engulf yards and swamp cesspools. When it rains, underground lakes pooling in basements near Millers Pond overwhehn homeowner pumps that were able to control flooding in the past (Newsday, March 12, 2007). Long Island has seen extensive growth and development over the last 100 years, due in part to it's proximity to the New York metropolitan area, as well as the abundance of fresh groundwater resources. This growth and development has generally resulted in the drawing down of groundwater in populated areas as a result of (1) increased groundwater pumping, (2) the installation of storm and sanitary sewers, and (3) increases in impervious surfaces which limit the infiltration of precipitation into the ground (USGS, WRIR 01-4165, 2002). This effect becomes less evident as you move from west to east across Long Island, following the trend of a decline in both population density and the level of sewering (while most of Nassau County is sewered, only the Atlantic Coast portions of Babylon, lslip and Brookhaven have sanitary sewers). While development is known to lead to overall declines in groundwater levels, development pressures also have led to construction in areas with chronic or historically recurrent shallow groundwater conditions. To date, a comprehensive delineation of areas of shallow groundwater flooding (shallow groundwater hazard areas) has not been undertaken for SC. Such areas may be generally prepared by comparing countywide groundwater elevations to topographic ground elevations. Shallow groundwater hazard areas · may be assumed to exist where groundwater elevations are within about 10 feet of the ground surface, as this is the typical depth below grade of structures that may be impacted (building foundations, septic systems and cesspools, etc.). While such mapping would have no current regulatory significance, it could support mitigation planning and support planning for further development and structure types in these areas. In the absence of such mapping, shallow groundwater hazard areas have been identified by symptomatic and anecdotal data, as available. Thus, known shallow groundwater problem areas are presented below as they have been presented to the Planning Committee by affected communities in the County. Shallow groundwater flooding problem areas identified to date include areas in Smithtown, lslip, Brookhaven, Huntington, Babylon, and Shelter Island. Northeast Branch of the Nissequogue River and Lake Ronkonkoma Perhaps the most widely recognized area affected by shallow groundwater flooding it located around Lake Ronkonkoma and the Northeast Branch of the Nissequogue River in Smithtown and parts of Brookhaven and islip. This area was the subject of a 1980 study entitled "Drainage Improvements including Groundwater Relief' prepared by H2M Corporation for the SC Department of Public Works (H2M, 1980). This study indicates that the Northeast Branch is a series of ponds and streams which brings water to New Mill Pond for ultimate discharge to the Long Island Sound via the Nissequogue River. Lake Ronkonkoma is situated within a groundwater flow regime which brings groundwater from the main Long Island groundwater divide (which lies approximately 1.2 miles north of the Lake) southward to the Great South Bay via groundwater flow and such surface tributaries as the Connetquot River. DMA 2000 ~azard Mitigation Plan ~ ~ffoik county. New Yo. rk 5.4.8-5 DRAFT- September 2007 SECTION 5.4.8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING The H2M study identifies twelve specific problem areas in the Northeast Branch of the Nissequogue River and Lake Ronkonkoma area~ and notes that the type, duration, cause, and history of the flooding problems in each of these areas varies. Mr. Ted Sanford, the Town Engineer in Smithtown, stated in May 2007 that the areas identified in the H2M study are still quite accurate, with several modifications (Area 12 eliminated, Area 11 south and west of Gibbs Pond Road eliminated, and Area 8 around the north half of Lake Ronkonkoma reduced to an area around four streets on the north side of the Lake, adjacent to the Great Bog). Figure 5-161 shows these shallow groundwater flooding hazard areas as modified with input from Mr. Ted Sanford of Smithtown Engineering. Figure 5-161. Shallow Groundwater Problem Areas in Smithtown Area Branch Brook Elementary School Legend - Y, mtrcc: Interpreted by Tetra Tech EM Inc. from the H2M Study Various sources estimate the number of properties and structures that may be impacted by shallow groundwater in this area. Approximately 3,002 parcels (most residentially developed) are located 'within thc impacted areas identified in Figure 5-161 (see Vulnerability Assessment - Impact on General Building Stock at the end of this profile). Thc H2 M Study summarized a number of groundwater flooding problems in the Northeast Branch of the Nisscquogue River and Lake Ronkonkoma area as follows: [~ / DMA 2000 Hazard Mitigation Plan 2 SUffolk c0untyl NeW Yoik 5.418~6 ,~ it:::I DRAFT- September 2007 SECTION 5.4.8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING · As of the date of the study, groundwater levels were found to be quite high throughout the area,. reflecting high amounts of precipitation over the previous five years. · A development boom in the late 1960s took place when water levels were very low as a result of severe drought in the early to mid 1960s. This drought period, from 1960 to 1966, was the most severe drought recorded on Long Island, and groundwater levels dropped Island-side as much as 5 to 10 feet. In this area, where groundwater levels are typically among the highest on the Island, the drop in water table actually exceeded 10 feet in places. · As recovery of groundwater levels occurred steadily from the late 1960s through the 1970s, certain areas began to experience groundwater-related flooding problems. High levels of precipitation in 1978 and 1979 resulted in hundreds of homes and many roadways being affected by groundwater- related flooding. · While brief periods of low precipitation may make existing problems seem to subside, these problem areas remain and can be impacted when precipitation returns to normal conditions. The "Lake Ronkonkoma Clean Lakes Study," prepared in 1986 by the SC Planning Department and SC Department of Health Services, provides further insight into the problems around Lake Ronkonkoma and corroborates the findings of the H2M study. The General Background in the study presents the following assessment of the problem: After Word War II, many people established year-round residency, and widespread development took place. During the 1960s a severe draught caused a general five to ten foot lowering of the water table in the Lake Ronkonkoma area. At the same time, a building bo. om occurred resulting in the development of the woodland areas as well as sites that were unsuitable far building because they were located in wetlands, and/or normally had a high water table. [During this period] former wetland and high water table areas were filled in and subsequently developed. Certain portions of the lake were filled and developed. The northern portion of the lake was formerly located where Smithtown Boulevard (CRI6) now separates the lake from the bog. This road was developed in the 1930s; the area south of CRI6 and north of the lake and the Old Causeway (Lake Shore Road) was also filled in and developed. The development of Steuben Boulevard required the filling in of the shallow portion of the lake and adjacent wetlands. The western shore was also filled using dredged material from the lake. During the years following the drought, the recurrence of normal rainfall patterns led to a rise in the water table level and the flooding of numerous basements (north, west and northeast of the lake). In some instances, even the first floors of homes located north of the lake were inundated with water. The residential area north of the lake near the intersection of Nichols Road, Browns Road and Alexander Ave. has had chronic flooding problems. During the early seventies, three recharge basins serving this residential area of Smithtown were interconnected by a system of gravity piping and discharged, via a pump station and force main, about one-half mile south into the Great Bog, west of Browns Road. Due to a rise in groundwater and lake levels in 1979, and a recurrence in 1984, the lake and the Great Bog became one body of water breached by Smithtown Boulevard, and many of the developed areas are experiencing extensive flooding problems. Today, as many as seventy homes in the general area have flooded basements, and roads near the lake are periodically flooded. There are approximately fifly additional acres adjacent to the lake that am flooded during periods when lake levels are high. Complicating the picture are homes that sat close to the water table even in dry weather. Both areas DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.8-7 DRAFT- September 2007 SECTION 5,4,8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING have low elevations. A former stream bed winds through neighborhoods by Millers Pond. The swampy area that abuts the damp homes on Charles Court sits at the same elevation as the surface of Lake Ronkonkoma, just across the street. A number of possible solutions and mitigation actions have been proposed over time, including in the H2M study, the Clean Lakes studies, and elsewhere. Mitigation actions that are currently being considered as viable, or are being initiated, are discussed in Section 6 of this Plan. Additional town-specific data on the groundwater flooding hazard is presented below. Town of Babylon The Town of Babylon reports that shallow ~roundwater has been a problem in Babylon since initial development over a hundred years ago. Town of Shelter Island Figure 5-162 shows areas impacted by shallow groundwater flooding as identified by Shelter Island officials. Figure 5-162 Shallow Groundwater Problem Areas in Shelter Island Source: Town of Shelter Island DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT- September 2007 5.4.8-8 SECTION 5.4.8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING Approximately 73 residential or undeveloped parcels) are located within the impacted areas identified in Figure 5-162 (see Vulnerability Assessment - Impact on General Building Stock at the end of this profile). Town of Huntington Officials from the Town of Huntington report two properties specifically impacted by shallow groundwater flooding conditions. A residence on Woodlot Lane report having to vacate the house temporarily due to its cesspool overflowing. Another residence on Radcliff Drive was also identified as having known shallow groundwater flooding issues. Previous Occurrences alld Losses Shallow groundwater flooding hazard areas in SC include those with chronic (persistent) problems, and those areas that experience problems on a cyclical basis in response to long-term precipitation trends. In the Lake Ronkonkoma and the Northeast Branch of the Nissequogue River area, impacts from shallow groundwater have occurred cyclically. The H2M study reports that some of the older homes in this area have flooding histories dating back to 1936, with documented events during 1951 and 1952. Since the drought period in the early to mid-1960s, impacts from shallow groundwater have been reported in several general events. As groundwater levels recovered during the late 1960s through the 1970s, the basements of certain homes experienced varying degrees of seepage and certain roadways began flooding periodically. High levels of precipitation in 1978 and 1979 exacerbated the problems, with hundreds of homes and many roadways suffering impacts (H2M - Vol. 1) In the early 1990s, part of Steuben Road- was abandoned after the town could no longer keep up with the repairs required due to the constant flooding INewsday, March 12, 2007). The shallow groundwater flooding impacts that are occurring presently began with heavy rains in October of 2005. As indicated previously, an estimated 3,002 parcels (primarily developed for residential use) are within the shallow groundwater flooding hazard areas. In addition to flooding into basements and crawlspaces, yard and street flooding is widely reported. Losses include the cost to (1) repair/retrofit basements, septic systems and cesspools, and replace basement utilities; (2) address mold abatement; (3) run pumps and dehumidifiers; and (4) address various health concems as both direct and indirect consequences. Also in this area is the Branch Brook Elementary School at 15 Ridgely Road in Hauppaugc. groundwater has been rising up into the septic system and causing mw sewage to flow into the school. The School District began pumping the septic tanks daily at a cost of $2,000, and is planning to reboild the septic system at a cost of $500,000 to $750,000 (Smithtown News; May 3, 2007). A further discussion of vulnerability and losses is provided in the Vulnerability Assessment at the end of this profilc. DMA 2000 Hazard Mitigation Plan ~ Suffolk Co~nlyl N~W YOrk DRAFT- September 2007 5.4-.8-9 SECTION 5.4,8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING Probability of Future Events As detailed previously, shallow groundwater flooding hazard areas in SC include those with chronic (persistent) problems and those areas that experience problems on a cyclical basis in response to long- term precipitation trends. Obviously, structures within areas where shallow groundwater conditions exist at all times would expect to be impacted with a 100% probability during times or normal precipitation. Those areas that suffer from cyclical shallow groundwater problems (for example, Lake Ronkonkoma and the North Branch of the Nissequogue River area) experience such events according to long-term precipitation trends. Since the drought period in the early to mid-1960s, impacts from shallow groundwater flooding have been experienced in three general time periods (1975-1985, peaking about 1979; 1989-1992; and 1995 to present). Based on these records and data on long-term precipitation trends presented earlier in this profile, the probability of occurrence for shallow groundwater flooding events in those areas experiencing cyclical impacts is considered frequent (that is, likely to occur more than once every 10 years). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.8-10 Draft - September 2007 SECTION 5.4.8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. For the shallow groundwater flooding hazard, areas identified as hazard areas include specific land areas identified by previous studies, citizen input, and town knowledge. The following text evaluates and estimates the potential impact of groundwater flooding hazard on SC, including: · Overview of vulnerability · Data and methodology used for the evaluation hnpact, including: ( 1 ) impact on life, safety and health of County residents, (2) general building stock, (3) critical facilities and infrastructure, and (4) economy · Further data collections that will assist understanding of this hazard over time · Overall vulnerability conclusion Overvie~ of Vuhlerability Shallow groundwater flooding is a significant concern in many parts of SC, particularly those identified in this hazard profile. To assess vulnerability, potential losses and impacts have been estimated. The shallow groundwater flooding hazard exposure and loss estimate analysis is presented below. Data aud Methodolog3r Input data collected and reviewed for the shallow groundwater flooding hazard includes local damage data and estimates from historic and current events, SC Real Property data, building stock data provided in HAZUS-MH, and other input from SC and local soumes. With regard to shallow groundwater flooding hazard areas, to date only affected areas in the Lake Ronkonkoma/North Branch parts of Smithtown and lslip, and Shelter Island have been identified with a level of detail to support the identification of potentially affected parcels, structures, and populations. To support the analysis of this hazard, parcel centroids were used as provided from SC Real Property. General building stock data was used as provided in HAZUS-MH, supplemented by local data regarding critical facilities and infrastructure lifelines. It is noted that when analyzing Census blocks against the identified shallow groundwater flooding hazard areas, many blocks fall only partly within the hazard delineations. For this purposes of this assessment, the general building stock and population/demographic data presented include only those blocks whose geometric centers fall within the identified hazard areas. Therefore, the assessment is likely to underestimate the total number of structures and population exposed. With current limited information regarding the severity of past impacts on specific properties, there is currently insufficient information to determine the severity of impact on population and structures exposed to the shallow groundwater flooding hazard. Impacts to life, health, and safety and structures are discussed below using the methodology described in this paragraph. Impact on Life, Health aud Safety Shallow groundwater flooding is not generally considered to pose an immediate danger to life; however, there are a number of health and safety concerns associated with the hazard. Health concerns are related to exposure to mold and groundwater contaminated by fecal coliform and hazardous materials, as well as stress. Safety concerns also include slips, trips and falls, both while addressing basement flooding problems, and when walking or driving on ice-covered surfaces in cold weather. [ DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.8-11 DRAFT- September 2007 SECTION 5.4.8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING Table 5-45 sulmnarizes the number of people, including vulnerable populations, living in the identified shallow groundwater flooding hazard areas. Smithtown 6,258 852 233 Islip 126 80 1 Shelter Island 163 TBD TBD Sources: Smithtown and lslip are HAZUS-MH, 2005. Shelter Island estimated as number of exposed parcels multiplied by 2.5 persons per parcel. Exposure represents the population living within the shallow groundwater flooding hazard areas that may. suffer the health and safety concerns associated with the hazard. As'previously noted, this estimate likely underestimates the number of people exposed. Further it is noted that the Branch Brook Elementary School at 15 Ridgley Road in Hauppauge is impacted by shallow groundwater flooding, with groundwater rising up in to the septic system and incidents of raw sewage entering the school. Per the New York State School Report Card Comprehensive Information Report (March, 2006), Branch Brook Elementary School had a 2005-05 enrollment of 452 students, and a staff of 32.

Exposure represents the number of parcels and structures located within the shallow groundwater flooding hazard areas that may be impacted. As previously noted, this estimate likely underestimates the numbers of structures exposed; as stated previously, the degree of impact to each parcel cannot be estimated with available data. Further data collection and evaluation could support estimates of costs per year or per event that may be associated with these events.

These data shows that an individual homeowner could be severely impacted by financial impacts associated with this hazard. hnpact on Critical Facilities and Infrastructure In addition to considering general building stock at risk, the risk of flood to critical facilities and infrastructure was evaluated. The Branch Brook Elementary School at 15 Ridgley Road in Hauppauge is impacted by shallow groundwater flooding, with groundwater rising into the septic system and incidents of raw sewage flowing into the school. The School District began pumping the septic tanks daily at a cost of $2,000, and is planning on rebuilding the septic system at a cost of $500,000 to $750,000 (Smithtown News; May 3, 2007). In certain areas, flooding has extended above the ground surface and impacted yards and roads throughout the hazard areas. The following impacts to roads have been identified: · In the early 1990s, part of Steuben Road was abandoned after the town could no longer keep up with repairs from constant flooding. (Newsday; March 12, 2007). · Roads along Smithtown Boulevard, and the parking lot of the Bavarian Inn, periodically flooded. (Newsday; July 10, 2007). · Adrian Lane, Schoolhouse Road (reported at 2007 Smithtown meeting). Impact on Economy Sufficient information was not available to perform a detailed assessment of estimated losses to the economy associated with this hazard. Potential impacts include closed businesses or schools if impacted DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.8-13 DRAFT- September 2007 SECTION 5.4.8: RISK ASSESSMENT - SHALLOW GROUNDWATER FLOODING by flooding, lost days of work if homeowners miss work to address home flooding, disruption of transportation if roads are flooded, and potential costs for illnesses and injuries that could be associated with the hazard. Additional Data Needs and Next Steps Over time, the County and participating jurisdictions will work together to leam more about the shallow groundwater flooding hazard, and support further mitigation efforts as discussed in Section 6 to reduce the losses within these areas. Comprehensive identification of shallow groundwater flooding hazard areas and associated impacts and losses also will support furore planning efforts. Overall Vulnerability Assessment The shallow groundwater flooding hazard is evaluated as a significant, localized threat, which was ranked overall as a "medium" risk overall for SC (see Table 5-7). This hazard can be managed and planned for through the mitigation strategies and specific activities outlined in Section 6. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 SECTION 5.4.9: RISK ASSESSMENT - FLOOD 5.4.9 FLOOD This section provides a profile and vulnerability assessment for the flood hazard. ItAZARD PROFILE This section provides profile information including: description, location and extent, previous occurrences and losses and the probability of future occurrences. Description The NYS HMP defines flooding as the accumulation of water within a water body which results in the overflow of excess water onto adjacent lands, usually floodplains. The floodplain is the land adjoining the channel of a river, stream, ocean, lake, or other watercourse or water body that is susceptible to flooding. A flood is a general and temporary condition of partial or complete inundation of normally dry land areas, resulting from: · Overflow of inland or tidal waters · Unusual and rapid accumulation of runoff or surface waters · Mudslides/mudflows caused by accumulation of water · A situation in which rainfall is so intense and severe and runoff so rapid that is precludes recording and relating it to stream stages and other information in time to forecast a flood condition (FEMA, 2004; NYS Disaster Preparedness Commission, 2004). Floods are one of the most common hazards in the United States, with effects that can be local (impacting a neighborhood or community) or very large (affecting entire fiver basins, coastlines and multiple states). Most communities in the United States have experienced some kind of flooding after spring rains, heavy thunderstorms, coastal storms, or winter snow thaws. Some floods develop slowly over a period of days, while others develop quickly. According to FEMA's National Flood Insurance Program (NFiP) Floodplain Management Requirements: A Study Guide and Desk Reference for Local Officials (FEMA-480), most floods fall into three categories: Riverine, Coastal and Shallow. Other types of floods include ice-jam floods, alluvial fan floods, dam-break floods, and floods associated with local drainage or shallow groundwater; however, these flood types are not as common throughout SC. Coastal and Riverine flooding are the main types of floods to impact SC and are discussed as follows: Coastal Flooding - Coastal flooding occurs along the coasts of oceans, the Gulf of Mexico, and large lakes. This is the most common type of flooding along a coastline. Coastal floods involve the submersion of land areas along the ocean coast and other inland waters caused by sea water rising over and above the normal tide action. Coastal flooding can result from a storm surge, which can result in weakening or destruction of coastal structures. Hurricanes and severe storms cause most coastal flooding, including "Nor'easters" which are severe storms that occur in the Atlantic basin and are extra-tropical in nature with winds out of the northeast. Information regarding Hurricanes, Severe Storms and Nor'easters are further discussed in separate sections of this HMP. Coastal flooding can result in the many problems identified for Riverine/Flash Flooding and can also include additional problems, such as beach erosion, loss or submergence of wetlands and other coastal ecosystems, salt water intrusion, high water tables, loss DMA ~000 t.-laz~;d Mitigation Pian £ s~ffoi~ ~o~ntyl New York' DRAFT- September 2007 5.4.9-1 SECTION 5.4.9: RISK ASSESSMENT - FLOOD of coastal recreation areas, beaches, parks and open space and/or loss of coastal structures (piers, bulkheads, bridges). Riverine Flooding - Riverine flooding occurs along a channel, which includes overbank and flash flooding. Riverine floods are the one of the most common flood types. Riverine floods occur when rivers and streams overflow their banks (overbank) and inundate low-lying areas. This type of flooding usually occurs after spring rains, heavy thunderstorms, or snowmelt. These floods can be slow or fast-rising, and generally develop over a period of days. Flash floods often have a dangerous wall of roaring water that carries rocks, mud, and other debris and can sweep away most things in their path. Flash floods usually result from intense storms dropping large amounts of rain within a brief period with little or no warning and can reach their peak in only a few minutes. They normally occur in the summer during the thunderstorm season. The most severe flooding conditions usually occur when direct rainfall is augmented by snowmelt. If the soil is saturated or frozen, stream flow may increase due to the inability of the soil to absorb additional precipitation. Flooding can also occur when a dam Breaks, producing effects similar to flash floods. Areas that are most susceptible to the effects of floods are low-lying areas that are near water or downstream from a dam. Riverine and Flash Floods are problematic in numerous ways, including but not limited to: water-related damage to the interior and exterior of buildings, especially homes; destruction of electrical and other expensive and difficult to replace equipment; loss of life; injury and proliferation of disease vectors; disruption of utilities, including water, sewer, electricity, com~nunications networks, and facilities; loss of agricultural crops and livestock; placement of stress on emergency response and healthcare facilities and personnel; loss of productivity, and displacement of persons from homes and places of employment (FEMA, 2004). Flooding can produce widespread impacts in both rural and urban areas. Any type of agricultural, commercial, residential and recreational development and natural communities (e.g. wetlands, marshes) located in a floodplain (inland or coastal) are vulnerable to flooding. Increasing urbanization in some areas enhances the threat of flooding if existing drainage systems cannot cope with the increased input of stormwater runoff and if increased pavement reduces natural water infiltration into the soil (increasing runoff). In rural areas, property damage caused by flooding can be devastating to farmers. When flooding occurs during the growing season, farmers can suffer widespread crop loss. In some cases, there may be an opportunity for a second planting of a less profitable crop. Livestock farmers may lose livestock if they are unable to find areas safe from rising floodwaters. This threat is primarily associated with flash flooding, which reduces the time available to plan and evacuate. Beach, dune, and bluff erosion and the washing away of structures are impact associated with coastal flooding. Flooding can pose several threats to residential'and commercial properties. Buildings can experience significant damage, sometimes beyond repair. Household furnishings and business inventories can be lost if dmre is not adequate time to remove items to safe locations. In addition to being at risk because of floodwater, people face the threat of explosions and fires caused by leaking gas lines along with the possibility of being electrocuted. Even wild animals, forced out of their homes and brought into contact xxith humans by floodwaters, can be a threat. Post-flood concerns can include mold growth on structures. Sex crc flooding can cause extensive damage to public utilities and disruptions to the delivery of services. Loss of power and communications can be expected. Drinking water and wastewater treatment facility may be temporarily out of operation, hnpacts of flooding on transportation are particularly noteworthy. Flooded streets and roads block transportation and make it difficult for emergency vehicles to respond to calls tbr service. Floodwaters can washout sections of roadway and bridges. Most importantly, the majority of fatalities that occur in floods are the result of people trying to dry on roads covered by floodwaters (Foster, Date Unknown). ~ ', DMA 2000 Hazaid Mitigation Plan £ Suffolk C0un~i New york itt; I DRAFT- September 2007 5.4.9-2 SECTION 5.4.9: RISK ASSESSMENT - FLOOD Location and Extent This section discusses the location and extent of coastal and riverine flood hazard areas in SC. SC {s primarily bounded to the north~ south, and east by coastal waters~ naturally creating 100-year and 500- year floodplains within the Towns~ Villages, and Hamlets located along the coastlines of the County. These areas are prone to frequent floods and/or inundation, as SC receives high amounts of precipitation, associated stonnwater run-off~ coastal storms, and elevated sea levels. In the case of a storm surge within the vicinity of SC, the South Shore of the County would be most at risk of flooding (Figure 5-163). A storm surge is an onshore gush of water associated with a low pressure weather system, typically a tropical cyclone. Storm surge is caused primarily by high winds pushing on the ocean's surface. Fi ure 5-163. Coastal Areas Along Long Island at Risk From Source: Clark, 2005 When severe thunderstorms or storms associated with hurricanes or tropical storms/depressions occur, they often result in coastal and riverine floods throughout SC. Flood hazard areas are defined as areas that would be inundated by a flood of a given magnitude. These areas are determined using statistical analysis of flood discharge data and hydraulic and topographic analyses. Tools such as FEMA's Flood Insurance Rate Maps (FIRM) show individual street maps with flood hazard areas indicated for each Town, Village and Hamlet throughout SC. Designated coastal and riverine flood hazard areas within SC include those low-lying areas located along the southern barrier islands (e.g., Fire Island), northern, southern and eastern coastlines, coastal waterbodies (e.g., bays, harbors, coves, inlets, and tidal tributaries), and streams, rivers, lakes and ponds throughout the County. Figure 5-164 illustrates the 100- and 500-year flood zones for SC. As identified by the NYSEMO, 27,029 of SC residential structures (5.9%) are located within a 100-year floodplain. HAZUS-MH estimates 31,600 residential structures (6.9%) are located within the 100-year floodplain; based on Census 2005 data (refer to vulnerability assessment for more detailed information). The 2004 NYS HMP indicated that the potential flood loss within the 100-year floodplain of SC could result in $7.7 billion in damages. HAZUS-MH estimates the replacement cost for residential structures damaged by the 100-year flood event is approximately $459,382,000. SC was ranked as the 2%most flood vulnerable county in NYS (Nassau County being the lst) based on potential flood exposure and vulnerability to loss (NYS, 2004). Figures 5-165 through 5-176 show coastal and riverine 100- and 500-year flood zones for SC and its participating towns, villages, and hamlets.

The program sponsored the collection of aerial photography and cross-shore topographic profiles from Coney Island to Montauk Point. For the purposes of organizing and classifying the profile data, the south shore has been divided into eight reaches: Coney Island, Rockaway Beach, Long Beach, Jones Beach, Fire Island, Westhampton, Ponds, and Montauk. Various flood zone maps of SC's coastline, as presented by this tool, are provided as Figures 5-177 through 5-181.

Base flood elevations (BFEs) derived from detailed hydraulic analyses are shown at selected intervals within this zone. Mandatory flood insurance purchase requirements apply. The BFE is the regulatory requirement for the elevation or floodproofing of structures. The relationship between the BFE and a structure's elevation determines the flood insurance premium. Zone AE and Al-A30 - Zones AE and Al-A30 when used on FIRMs, correspond to 100-year floodplains that are determined by a Flood Insurance Study using prescribed and detailed methods and analyses. In most instances, BFEs derived from the detailed hydraulic analyses are shown at selected intervals within this zone. Mandatory flood insurance purchase requirements apply. Zone A - Zone A is the flood insurance rate zone that corresponds to the 100-year floodplain and is determined by a Flood Insurance Study using approximate methods. Because detailed hydraulic analyses are not performed for such areas, no BFEs or depths are shown within this zone. Mandatory flood insurance purchase requirements apply. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.9-19 SECTION 5.4.9: RISK ASSESSMENT - FLOOD Zone X - Zone X is the flood insurance rate zone\ corresponding to areas that are outside of the 100-year floodplain, areas of 100-year sheet flow flooding where average depths are less than I foot, areas of 100- year stream flooding which contribute to drainage areas less than I square mile, or areas protected from the 100-year flood by levees. No BFEs or depths are shown within this zone. Mandatory flood insurance purchase requirements do not apply. Zone X500 - Zone X500 represents an area inundated by 500-year flooding; an area inundated by 100- year flooding with average depths of less than 1 foot or with drainage areas less than I square mile; or an area protected by levees from 100-year flooding (FEMA, 2006). Coastal flooding throughout SC, particularly along the southern shoreline, results from the interaction of topography and water level variations. Topographic elevation, slope, and shoreline orientation can determine the extent to which high water will inundate the landscape adjacent to the coast. Likewise, the extent to which water levels can rise to flood the land is dependent on tidal conditions, sea level rise, wind, waves, coastal storms, and other conditions, including human contributions (NYS Department of' State, 2000). In the case of a riverine flooding, once a river reaches flood stage, the flood extent or severity categories used by the NWS include minor flooding, moderate flooding, and major flooding. Each category has a definition based for associated property damage and public threat. · Minor Flooding - minimal or no property damage, but possibly some public threat or inconvenience · Moderate Flooding - some inundation of structures and roads near streams..Some evacuations of people and/or transfer of property to higher elevations are necessary. · Major Flooding - extensive inundation of structures and roads. Significant evacuations of people and/or transfer of property to higher elevations. The severity of riverine flooding depends not only on the amount of water that accumulates in a period of time, but also on the land's ability to deal with this water. The amount of water that may accumulate depends on the size of rivers and streams in an area. Precipitation and snow melt are related accumulation factors. An equally important factor impacting flood severity is the land's ability to absorb water. When it rains, soil acts as a sort of sponge. When the land is saturated (soaked up all the water it can) any more water that accumulates must flow as runoff. Paved areas are less pervious to water than open land; therefore, development can decrease the soil's ability to act as a sponge and can increase flood severity. Other Potential Hazard Areas Shelter Island has identified roadways that are impacted by flooding due to tidal waters. These roads include sections of Brander Parkway, Chequit Avenue, Gardiners Bay Drive, Midway Road, Neck Road, Ram Island Drive, Shore Road, Thompson Road, Winthrop Road, and portions of Route 114 in the northern and southern portion of the island. Figure 5-182 illustrates these areas identified by the Town.

Some of these items overlap with items shown under the Hurricane and the Nor'Easter Sections of this report. According to FEMA's 2002 NFIP - Program Description, the U.S. Congress established the NFIP with the passage of the National Flood Insurance Act of 1968. The NFIP is a Federal program enabling property owners in participating communities to purchase insurance as a protection against flood losses in exchange for State and community floodplain management regulations that reduce future flood damages. Participation in the NFIP is based on an agreement between communities and the Federal Government. if a community adopts and enforces a floodplain management ordinance to reduce future flood risk to new construction in floodplains, the Federal Government will make flood insurance available within the community as a financial protection against flood losses. This insurance is designed to provide an insurance alternative to disaster assistance to reduce the escalating costs of repairing damage to buildings and their contents caused by floods (FEMA, 2002). There are three components to NFIP: flood insurance, floodplain management, and flood hazard mapping. Nearly 20,000 communities across the United States and its territories participate in the NF1P by adopting and enforcing floodplain management ordinances to reduce future flood damage. In exchange, the NFIP makes Federally-backed flood insurance available to homeowners, renters, and business owners in these communities. Community participation in the NFIP is voluntary. Flood insurance is designed to provide an alternative to disaster assistance to reduce the escalating costs of repairing damage to buildings and their contents caused by floods. Flood damage is reduced by nearly $1 billion a year through communities implementing sound floodplain management requirements and properly owners purchasing of flood insurance. Additionally, buildings constructed in compliance with NFIP building standards suffer approximately 80 percent less damage annually than those not built in compliance. In addition to providing flood insurance and reducing flood damages through floodplain management regulations, the DMA 2000 Ha~aid ~itig~ii0~ Pi-~n 2 s~ff0ik c0uniyl New York DRAFT- September 2007 5.4.9-22 SECTION 5.4.9: RISK ASSESSMENT - FLOOD NFIP identifies and maps the Nation's floodplains. Mapping flood hazards creates broad-based awareness of the flood hazards aod provides the data needed for floodplain management programs and to actuarially rate new construction for flood insurance. According to the NF1P statistics, which are updated on a regular basis, over 15,300 flood-related claims have been made between January 1978 and May 2007 by SC (Table 5-48).

A RLP as defined by FEMA is an NFIP-insured property that, since 1978 and regardless of any changes in ownership during that period, has experienced an3 of the following: · Four or more paid losses in excess of $1,000; · Two paid losses in excess orS 1,000 within any rolling 10-year period; or · Three or more paid losses that equal or exceed the current value of the insured property. ; / DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.9-24 LT'CI DRAFT- September 2007 SECTION 5.4.9: RISK ASSESSMENT - FLOOD RLPs comprise only I to 2 percent of the flood insurance policies currently in force nationally, yet they account for 40 percent of the country's flood insurance claim payments. The NFIP is concerned with RLPs because structures that flood frequently strain the National Flood Insurance Fund. In fact, the RLPs not only increase the NFIP's annual losses and need for borrowing; they also drain funds needed to prepare for catastrophic events. Community leaders and residents are also concerned with the RLP problem because residents' lives are disrupted and may be threatened by the continual flooding. The key identifiers for RLPs are the existence of flood insurance policies and claims paid by those policies. FEMA-sponsored programs, such as the Community Rating System (CRS), require participating communities to identify repetitive loss areas. A repetitive loss area is that portion of the floodplain where buildings or RLPs have been subject to repetitive flooding. The repetitive loss list maintained by FEMA is based on flood insurance payments. According to the NYSEMO Comprehensive Emergency Management Plan, as of 2004 SC has identified 1,717 NFIP repetitive flood loss properties (the 2nd highest number for a County in NYS). However, NFIP loss statistics as of March 31, 2007 indicates that SC has 1,616 repetitive loss properties. Figures 5-183 through 5-185 illustrates the properties with repetitive, flooding, and properties with policies and claims within the County, as of March 2007, respectively.

In regards to NYS, according to FEMA and the 2004 NYS HMP, DR 702 was declared for a flood event that took place across the southeastern NYS (Figure 5-16) and resulted in $11.9 million in property damages. Public assistance reimbursements to SC for emergency protective measures responding to storms and flooding, the repair of damaged infrastructure, and debris removal was not reported in the materials available for review. August 11, 1989: According to SHELDUS, this flood event resulted in $2.5 million in property damages to SC. However, no other sources revealing additional information about this event were identified in materials reviewed to develop this plan. January 9, 1993: According to the NOAA-NCDC storm query for SC, a strong high pressure system ove, r the northeastern states and a nearly stationary front lying well offshore produced a strong northeasterly flow across the area resulting in coastal flooding. In Westhampton a few homes already badly weakened as a result of a December 1992 Nor'easter collapsed because their foundations were further undermined by this event. Estimates of property damage were unavailable in the materials reviewed to develop this plan. April 7, 1993: According to the NOAA-NCDC storm query for SC, a combination of high tides and a storm located off the middle Atlantic coast generated some localized coastal flooding during the late evening hours within SC. A couple of coastal roads were washed out and five homes along Dune Road were lost to the sea. Cost estimates of property damage were unavailable in the materials reviewed for this plan. July 31, 1996: According to the Northeast Regional Climate Center (Cornell University) (NRCC), widespread flooding throughout multiple counties occurred on July 31, 1996. Street flooding averaging 1 to 3 feet deep, people stranded in cars, and minor mudsiides resulted from this flooding event. Cost estimates of properly damage were unavailable in the materials available for review. NOAA-NCDC indicates that the hardest hit counties in NYS included Richmond, Kings, Queens, Nassau, and Western Suffolk. In Western SC, widespread street flooding was reported at Melville and West Islip. Water was up to 3 feet deep along some of the low-lying streets in Melville. In Eastern SC, water was up to 2 feet deep along several streets in Southampton. Cost estimates of property damage were unavailable in the materials reviewed for this plan. October 19, 1996: According to the results of a NOAA-NCDC storm query for SC, heavy flood- producing rains along with minor to major coastal flooding occurred on October 19, 1996. Heavy rain caused serious widespread street and drainage system flooding along the Long island Expressway (LIE) through Nassau and Suffolk Counties. Selected rainfall amounts documented for SC ranged from 2.10 inches at Farmingdale Airport to 5.86 inches at Riverhead. Cost estimates of property damage were unavailable in the materials reviewed to develop this plan. August 20, 1997: According to the NOAA-NCDC storm query for SC, a low pressure system created coastal flooding along the northern and southern coastline of SC. A stretch of Harbor Beach Road in Mount Sinai (north shore of SC), was submerged under at least 2 feet of water. About 50 people were stranded on the Cedar Beach peninsula for about 4 hours. Street flooding was reported in Port Jefferson. Coastal flooding was also reported across parts of the south shore of SC extending from Babylon east to Southampton. Cost estimates of property damage were unavailable in the materials reviewed to develop this plan. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.9-32 SECTION 5.4.9: RISK ASSESSMENT - FLOOD June 13, 1998: According to the NOAA-NCDC storm query for SC, a line of thunderstorms developed and moved east over the area on this date. Thunderstorms produced torrential flash flooding rains and frequent lightning. Torrential rains resulted in widespread, serious flooding of streets, poorly drained areas, Iow-lying areas, home basements, and small streams. Lightning struck many homes and ignited fires that damaged them. In SC, rivers of moving water foruled rapidly on streets. In Lindenhurst, waves were visible on Sunrise Highway. Up to 3 feet of water also inundated streets in Babylon on Sunrise Highway. In Mastic, water rapidly flowed from Montauk Highway into a residential area and flooded basements and the first floors of houses. In SC, lightning struck the television antenna on a home and traveled to the attic where it ignited a fire (Zophar Mills Road in Wading River). Cost estimates of property damage were unavailable in the materials reviewed to develop this plan. April 20, 2000: According to the NOAA-NCDC storm query for SC, a series of intense thunderstorms moved north to northeast across Nassau and Western Suffolk Counties. The thunderstorms were accompanied by torrential rainfall that produced widespread severe flooding of low-lying and poorly drained areas and frequent and intense lightning strikes. Rainfall amoun}s ranged from around 3 to 7 inches. Significant and widespread ponding of water caused the closure of several stretches of road such as from Route 109 to Wellwood Avenue along the Sunrise Highway in Lindenhurst and stretches of Park Avenue and Siegel Boulevard in Babylon Village. Many cars were trapped by rising flood waters in Babylon, necessitating several rescues. Frequent and intense lightning strikes ignited fires and caused damage to many houses throughout Nassau and Suffolk Counties. Lightning struck a house and ignited a house fire on Tahlulah Lane in West Islip. Lightning blew a 4-inch hole in the siding of a house on Oakwood Road in Huntington Station. Houses were also struck by lightning in Floral Park, Port Washington and Hicksville. Cost estimates of property damage were unavailable in the materials reviewed to develop this plan. Selected rainfall amounts within SC ranged from 2.40 inches at West Islip · to 4.92 inches at Farmingdale Republic Airport. Spotters measured 4.24 inches at Lake Grove, 4.17 inches at Centerport, and 3.66 inches at Deer Park. August 29, 2002: According to the NOAA-NCDC storm query for SC, rain developed as a low pressure wave formed along the Mid Atlantic Coast. With wet antecedent conditions in place, periods of torrential rain resulted in widespread and significant flooding of low lying and poor drainage areas. Many spotters reported street flooding with road closures throughout these areas. In Western SC, flooding was reported at the following locations: · In Amityville, County Line Road was flooded north of the Sunrise Highway. · In Babylon Village, flooding was reported at the intersection of Stowe Ave. and Bulger Street. · In Huntington, flooding occurred along New York Avenue (Route 110) · In Melville, flooding was reported at the intersection of Sweet Hollow Road and Walt Whitman Road. · In Wantagh, flooding was reported on Old Mill Road. · In Nesconset, a section of Alexander Ave. and Jericho Turnpike was flooded. · In addition, spotters reported street flooding in Saint James. Total rainfall associated with the storm in Western SC ranged from 3.88 inches in Setauket to 5.40 inches in Amityville.

NOAA-NCDC indicated that Sunrise Highway closed with cars stranded due to major flash flooding. This event dropped between 3 and 6 inches across Southeastern NYS. September 15, 2005: Torrential rain produced widespread flash flooding along portions'of both the north and south forks of Eastern Long Island. Total rainfall associated with the storm ranged from 5 to 8 inches. Hourly precipitation rates were estimated as ranging up to 2 to 3 inches per hour. Many roads were flooded between Matfituck and Cutchogue, where spotters measured 7.67 inches of rain at Mattituck and 7.03 inches of rain at Cutchogue. These roads included Sound and New Suffolk Avenues in Mattituck and Oregon and New Suffolk Avenues in Cutchogue. Many roads were flooded in the Township of Southampton, mainly between North Sea and Sag Harbor along the north shore of the south fork and from east of Hampton Bays to East Hampton Airport along the south shore of the south fork. These flooded roads included: County Road 39 and Head of Ponds Road. Rainfall measurements ranged from 4.97 inches in Southampton to 6.31 inches in 'Bridgehampton (NOAA-NCDC, 2006). As identified by Eyewitness News ABC7, additional flooding was identified in the Township of Huntington (Figure 5- 1861. Figure 5-186.

Many roads were flooded between Mattituck and Cutchogne, where spotters measured rainfall of 7.67 inches at Mattituck and 7.03 inches at Cutchogne. These roads included Sound and New Suffolk Avenues in Mattituck and Oregon and New Suffolk Avenues in Cutchogue. Many roads were flooded in the township of Southampton, mainly between North Sea and Sag Harbor along the north shore of the south fork and from east of Hampton Bays to East Hampton Airport along the south shore of the south fork. A few flooded roads included County Road 39 and Head of Ponds Road. Rainfall measurements ranged from 4.97 inches in Southampton to 6.31 inches in Bridgehampton. Cost estimates of property damage were unavailable in the materials reviewed to develop this plan Probability of Future Events FEMA FIRMs delineate special flood hazard areas and the risk premium zones in a community. These special flood hazard areas identify locations that have a chance of being flooded in any given year. As shown on Figure 5-164 and as identified in the Atlantic Coast of New York Monitoring Program Data Viewer maps, SC predominantly has 100-year and 500-year flood designations along the Barrier Islands and southern and eastern coastline of the County. The 100-year flood designation means the area has a one-percent chance of flooding in any given year. A structure located within a 100-year floodplain has a 26 percent chance of suffering flood damage during the term of a 30-year mortgage. Similarly, the 500-year flood designation means the area has a 0.2- percent chance of flooding in any given year. Earlier in this section, the identified hazards of concern for the SC were ranked. The NYS Hazard Mitigation Plan conducts a similar ranking process for hazards that affect the State. The probability of occurrence, or likelihood of the event, is one parameter used in this ranking process. Based on historical records and the above definitions, the probability of occurrence for flood events in SC is considered frequent (that is, likely to occur more than once every 5 years). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.9-35 SECTION 5.4.9: RISK ASSESSMENT - FLOOD VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. For the flood hazard, the hazard areas identified in SC include the riverine (A, AE, AH, and AO zones) and coastal (V and VE zones) 100- and 500-year flood plains. The following text evaluates and estimates the potential impact of flooding on SC including: · Overview of vulnerability · Data and methodology used for the evaluation · Impact, including: (1) impact on life, safety and health of county residents, (2) general building stock, (3) critical facilities, and (4) economy · Further data collections that will assist understanding of this hazard over time · Overall vulnerability conclusion Overview of Vulnerability Flood is a significant concern for SC. To assess vulnerability, potential losses were calculated for the riverine and coastal hazard areas for 100-year and 500-year MRP flood events. The flood hazard exposure and loss estimate analysis is presented below. Data and Methodology Input data collected and reviewed for the flood hazard includes local spatial data from historical flood events, FEMA Quality 3 (Q3) flood polygon data which delineate the 100- and 500-year flood plain boundaries; the Sea, Lake and Overland Surges from Hurricanes (SLOSH) model outputs: and input from the residents and the Planning Committee. NOAA's Environmental Sensitivity Index (ES1) was used to characterize the SC shoreline. Population data were taken from HAZUS-MH and are based on the most recent census conducted in 2000 (FEMA 2004). General building stock data was used as provided in HAZUS-MH, supplemented by local data regarding critical facilities and lifelines. A flood polygon is a GIS vector file outlining the area exposed to the flood hazard. HAZUS-MH generates this polygon at the end of the flood computations in order to analyze the at-risk inventory. The HAZUS-MH methodology was customized to analyze the flood hazard for SC. The modeling approach used FEMA Q3 flood zone flood polygon data and USGS Digital Elevation Model (DEM) data to estimate the base elevation. The coastal damage functions in HAZUS- MH MR2 are not correct. To model coastal flooding, the damage functions in HAZUS-MH Flood Wizard were replaced with the coastal damage functions from HAZUS-MH MRI. Losses were estimated for a 100- and a 500-year MRP flood event. The 11 residential and 10 commercial occupancy classes available in HAZUS-MH were condensed into the following occupancy classes (residential, commercial, industrial, agricultural, religious, government, and educational) to facilitate the analysis and the presentation of results. Residential loss estimates address both multi-family and single family dwellings. In addition, impacts to critical facilities were evaluated for the 100-year and 500-year MRP flood events. A GIS shape file is a type of GIS vector file that was developed by ESRI for its ArcView software. This type of file contains a table and a graphic. The records in the table are linked to corresponding objects in the graphic. Population data were taken from HAZUS-MH and are based on the most recent Census data included in HAZUS-MH. Impacts to vulnerable populations are considered by evaluating the number of persons that DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.9-36 DRAFT - September 2007 SECTION 5.4.9: RISK ASSESSMENT - FLOOD qualify as vulnerable that are living in the flood-prone areas. Also, consideration of those in vulnerable structures (e.g., mobile homes) is conducted using the available data on these types of structures in the County. Impact on Life, Health and Safety HAZUS-MH was used to run flood scenarios, including for 100- and 500-year MRP flood events. These MRP flood events am generally those considered by planners and evaluated under federal programs such as the NFIP. The population exposed to the 100- and 500-year MRP flood events (both riverine and coastal) was evaluated using HAZUS' Flood Wizard. Table 5-50 lists the population exposed to in the 100- and 500-year zones for both riverine and coastal special flood hazard areas (SFHA). Table 5-50.

Exposure represents the population living in or near flood plain areas that could be impaclcd should a flood event occur. For this project, the potential population impacted is used as a guide lo consider the potential maximum number of persons that may be displaced or require shelter during a flood. The total number of injuries and casualties resulting from flooding is generally limited based on advance weather forecasting, blockades, and warnings. Therefore, injuries and deaths generally are not anticipaled if proper warning and precautions are in place, such as are developed in SC (MPC - Please DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.9-37 SECTION 5.4.9: RISK ASSESSMENT - FLOOD col~rnO. Ongoing mitigation efforts should help to avoid the most likely cause of injury, which results form persons trying to cross flooded roadways or channels during a flood. Impact on General Building Stock After considering the population exposed to the flood hazard~ the value of general building stock exposed to, and damaged by, the t00- and 500-year MRP flood events was evaluated using HAZUS' Flood Wizard. Potential damage is the modeled loss that could occur to the exposed inventory, including structural and content value. Table 5-51 shows the total number of buildings located in the 100- and 500- year flood zones. Table 5-52 shows the exposed value of building stock for the various categories of building stock and Table 5-53 lists the estimated dollar value of loss associated with the riverine, coastal, and total 100- and 500-year MRP flood zones events. In addition to total building stock modeling, individual data available on flood policies, claims, and RLP were analyzed. FEMA Region 2 provided the addresses of residential properties with NF1P policies, past claims, and multiple claims (RLPs). This data was then geocoded and overlain with jurisdictional boundaries and the boundaries of the 100-year and 500-year floodplains, using GIS. Table 5-54 lists the number of polices, claims, and RLP statistics for SC. Figures 5-183 through 5-185 earlier in this section illustrate the number of policies, claims and RLP statistics, respectively.

Greater than 99% of the exposed buildings are residential. The total (riverine and coastal) estimated residential loss (building structure and contents replacement value) for the 100-year flood event is $459,382,000, or 4.1% of the total exposed residential building replacement value that could be impacted by the 100-year flood (coastal and riverine). The total estimated residential loss for the 500-year flood event is $739,671,000, or approximately 5.2% of the total exposed residential building inventory could be impacted by the 500-year flood. This demonstrates the significant risk the flood hazard incurs, especially to residential structures. Impact on Critical Facilities HAZUS-MH estimates the probability critical facilities may sustain damage as a result of a 100-year and 500-year MRP event. Additionally, HAZUSoMH estimates the loss of use for each facility in number of days to re, turn to 100% functionality. The complete list of critical facilities impacted by the 100-year and 500-year MRP events identified by HAZUS-MH was submitted to the County and participating jurisdictions.

Additional Data and Next Steps Over time, the County will continue to work together with local, state, and federal entities to learn more about the flood hazard, enhance participation in FEMA's NFIP, and support further mitigation efforts as discussed in Section 6 to reduce the losses when future flood events occur. Refinement of floodplain maps and improvement of local inventory data will support refined analyses using the flood model over time. Future evaluations may apply the HAZUS-MH model to study particular reaches of concern in DMA 2000 i-laza;d Mitigaii0n Plan - Suffolk coUnty, New York DRAFT- September 2007 5.4.9-58 SECTION 5.4.9: RISK ASSESSMENT - FLOOD greater detail. Also, the model may be used to estimate the impact of particular mitigation activities that could be implemented to reduce flood risk. Also, as new or refined flood maps are created and development and mitigation efforts occur, future evaluations (for exmnple, through updates to this Plan) should consider any changes to the flood toss estimates presented in this Plan. Overall Vulnerability Assessment The flood hazard is evaluated as a significant threat, which was ranked overall for SC as a "medium" risk (see Tables 5-6 and 5-7). This hazard can be managed and planned for through the mitigation strategy and specific activities outlined in Section 6, which build on efforts already undertaken by the County and participating jurisdictions. DMA 2000 ,a~a;d Mitigation ~i~n 2 §~ffolk County, New York DRAFT - September 2007 5.4.9-59 SECTION 5.4.t0: RISK ASSESSMENT - WILDFIRE 5.4.10 WILDFIRE This section provides a profile and vulnerability assessment for the wildfire hazard. H A ZA RD PRO F I L Ii; This section provides profile information including description, location and extent, previous occurrences and losses and the probability of future occurrences. Description A wildfire is any instance of uncontrolled burning in grasslands, brush, or woodlands (NYSEMO, 2004). Wildfire is further defined as an uncontrolled fire spreading through vegetative fuels, exposing and possibly consuming structures (FEMA, 2004). Wildfires can be ignited by lightning and, most frequently, by human activity including smoking, campfires, equipment use, and arson. There are three different classes of wildfires including surface fires, ground fires, and crown fires. Surface fires are the most common type and bum along the floor of a forest, through needles, leaves, grasses, fallen branches and low shrubs. Ground fires burn on or below the forest flo6r, smoldering through the decomposition layer (duff) and incorporated root systems, during periods of drought. Crown fires are those that burn primarily in the leaves and branches of trees, spreading from tree to tree above the ground (FEMA, 1993). On Long Island, wildfires are typically described as a "brush fire." Wildfires pose a great threat to life and property, particularly when they move from forest or rangeland into developed areas. More than 140,000 wildfires bum an average of 5 million acres annually in the United States, causing millions of dollars in damage (FEMA, 2005). Since 1990, more than 900 homes have been destroyed each year as a result of wildfire and even a relatively small fire can cause substantial losses (NYSEMO, 2004). For example, the 1991 Oakland/Berkeley hills wildfire in California burned almost 3,000 homes on just 1,610 acres of land. The potential for wildfire, and its subsequent development (growth) and severity is determined by several factors including the presence of fuel, the area's topography, and air mass. These factors are described below: Fuel Various fuels characteristics impact wildfire behavior and intensity, including: the type of fuel (vegetation or a structure), its "burning qualities" (chemical and physical properties), the horizontal continuity of the fuel, its vertical arrangement and its moisture level influence wildfire behavior and intensity (FEMA, 2004). Grasses bum quickly when compared to Pitch Pine, Scrub Oak and Ericaceous shrubs which are extremely volatile fuels (Kurtz, 2006). Grassland, shmbland, and forest fires all have the potential to injure firefighters and destroy valuable infrastructure including homes and businesses. Fuel may include living and dead vegetation on the ground, growing on the surface as brush and small trees, and aerial fuel (for example, tree canopies). Man-made structures are also potential fuel sources for wildfire. Aggressive fire suppression DMA 2000 Hazard Mitigation PIan 2 Suffolk ~ouniyl ~ew Yoik DRAFT- September 2007 SECTION 5.4.'10: RISK ASSESSMENT - WILDFIRE and forest management practices over the past century have allowed fuel to accumulate, which can increase the risk ora wildfire. The vegetative patterns on Long Island are a result of two main processes, fire and substmte/soil composition (Brookhaven National Laboratory, 2003). When colonists arrived on Long Island three to four hundred years ago, the vegetative pattems were dominated by pitch pine scrub oak woodlands and warm season grasslands. Bordering the Hempstead Plains in central Nassau County (unique grassland dominated by switch gross and bluestem) was the Oak Brush Plains of western Suffolk County. This area was dominated by shrubby growth of scrub oak mixed with other oak species and pitch pine. The next major vegetative group extending eastward through the remainder of Suffolk County was a mix of pitch pine, pine-oak, and oak-pine forests as well as pitch pine scrub oak shrublands and woodlands. In the central portion of this area (in the areas now designated as Eastport and Westhampton) were the dwarf pine plains, an area where very sandy soils coupled with frequent crown fires produced a globally-rare, stunted pitch pine scrub oak ecosystem. On the south shore's coastal plain, Pine Barrens vegetation also were present. Only on the noah shore of Long Island included hardwood trees of any notable size. Except for the Hempstead Plains, which have been largely replaced by development, most of the original Long Island vegetative patterns still exist to varying degrees. A large portion of the native habitat in the eastern half of the Suffolk County is protected x~ithin the Central Pine Barrens (Brookhaven National Laboratory, 2003). Area Topography Topography can impact the wildfire hazard both in terms of the slope (upward or downward incline or slant of the land) and the elevation of land. The slope and terrain affect the movement of air and fire; the greater the slope, the more quickly a fire can travel (FEMA, 2004; NYSEMO, 2004). Hot gases rise in front of fire along a slope face, pushing fire up to four times faster than on level ground. Most of the current topographic features of Long Island, were created in the Wisconsin glacial stage. Glacial ice sheets moved south to Long Island and stopped in the middle section of the island. Glacier ice sheets deposited rock and soil, creating the glacier formed ridge of land known as the Ronkonkoma Moraine. This ridge runs from Queens County through central Suffolk County and easterly past Montauk Point into the Atlantic Ocean. A second glacier terminated from Queens to Orient Point along the northern edge of Long Island creating the Harbor Hill Moraine. As each glacier melted, streams were created and carried tremendous volumes of sand and gravel in a generally southern direction. This material deposited to create the gently sloping sandy and well drained outwash plains to the south of each of the two moraines (NYS-DEC Peconic Headwaters Unit Management Plan). In the study area, elevations range from a Iow of mean sea level (msl) along the coast to a. high of 295 feet above msl (amsl) at Bald Hill. Slopes in the Central Pine Barrens are generally even to gently rolling, ranging from 0 to 30 percent. Sand and soil deposit patterns greatly influence the type of vegetation growing and the associated fire return interval. Sandy, nutrient-poor, well-drained soils tend to have a higher percentage of fire adapted vegetation that is adapted to fire, including more frequent localized droughts and fire return intervals. Air Mass The air mass can impact wildfire through climate (including, temperature, relative humidity), local wind speed and direction, cloud cover, precipitation amount and duration, and the stability of the atmosphere at the time of the fire. For example, significant local winds at the time of a wildfire can cause a wildfire to spread rapidly. DMA 2000 Hazard Mitigaii0n Plan - Suffolk county, New York 5.4.10-2 DRAFT- September 2007 SECTION 5.4. t0: RISK ASSESSMENT - WILDFIRE The climate of Long Island is mild: it is largely influenced by the Atlantic Ocean. The local climate is categorized as humid continental, meaning it is dominated by continental influences related to the proximity of the ocean (Brookhaven National Laboratory, 2004). The average annual relative humidity over the past 8 years is 75% in the morning and 56% in the afiemoon (NRCC, Comell, 2006). Average temperatures are wannest in July and August and coldest in January and February. The average summer temperature in Suffolk County is 71.9°F. Temperature extremes in the summer are generally tempered by cooling ocean breezes. The average winter temperature is 32.4°F. Average annual rainfall totals are reported to be 45 inches for some areas in the Central Pines Barrens; however, there have been several times in the past half century when annual rainfall has been 10 inches less than normal. Local winds, which are a part of the air mass factor, can come from all directions in the study area; when under a stable high pressure air mass, with light winds, a sea breeze often develops shifting winds to the south and southwest while slightly, increasing humidity. The unpredictability and uncertainty of wind directions and speeds makes fire prediction and suppression more challenging. Wind speeds greater than. 10 miles per hour can cause wildfires to spread rapidly and can increase the flame heights that occur (Central Pine Barren Wildfire Task Force, 1999). Large crown fires on Long Island are typically associated with wind events and tend to make their large runs for only a few operational periods (days). Wildfires typically occur on Long Island during two main seasons. Most wildfires occur in the spring, from early March through early July; fires during this period typically bum fuels on the forest floor and understory. During the second fire season, which lasts from late summer through early autumn, fires are not as frequent but have the capacity to become larger and bum the crowns of the forest canopy. According to the NYS Plan, NY is most vulnerable to wildfire hazard events from "the end of the snow pack until leaf out and the end of August". However, a growing number of fire district managers across the United States have noted that because of persistent drought conditions, increasingly hot and dry weather, and changing weather patterns across the country, the fire season is now approaching a year- round threat. Location and Extent The NYS Plan identifies the Mitigation Planning Area Number 1, which includes Suffolk County, as an area with a special risk for wildfire. It may be assumed that any open land areas are susceptible to wildfire; however, the risk to life and property is greatest where forested areas adjoin urbanized areas (high density residential, commercial, and industrial); these areas are known as the wildland/urban interface (WUI) zone. As a result of the tremendous growth in residential, commercial, and industrial occupancies throughout Suffolk County, and a shift from urban to suburban development, there has been increasing development in previously undeveloped areas, including encroachment on the WUI, and a corresponding increase in the risks posed to people and property. Central Pine Barrens Ecology and Wildfire Profile The Central Pine Barrens on Long Island is a forested area of approximately 102~500 acres within the central and eastern portions of Suffolk County; this area has an extensive history and ongoing risk of frequent wildfire. Figure 5-188 shows a detailed map of the Central Pine Barrens, which include parts of the Towns of Brookhaven, Riverhead, and Southampton and is legally divided into a 55,000 acre Core Preservation Area and a 47,500 acre Compatible Growth Area (Central Pine Barren Wildfire Task Force, 1999). Pre-fire planning and wildfire suppression in the area are coordinated by the Central Pine Barrens Wildfire Task Force, which maintains a Fire Management Plan (finalized in 1999) that provides a comprehensive evaluation of the issues associated with wildfire in the Central Pine Barrens. The Fire Management Plan is currently under revision. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.10-3 DRAFT- September 2007 SECTION 5.4.10: RISK ASSESSMENT - WILDFIRE Figure 5-188. Central Pine Barrens Area Detail ('I:X/'lR&I PINt B;~[4RI'N'~ \ltl Source: Central Pine Barrens Wildfire Task Force, 1999. At the center of the Central Pine Barrens is a mosaic of forests, coastal plain ponds, marshes, and streams. The three forest types, pitch pine-tree oak (covering approximately 35 percent), tree oak-pitch pine (55%), and pitch pine-scrub oak-heath woodlands and shmblands (7%), are predominantly fire dependent (meaning that many of the species have adapted to and depend on periodic fire f6r long-term survival) (Kurtz, 2007). Pine Barrens are found on quick-draining soils with low nutrient content and high acidity. To help retain moisture, many of the plant species produce waxes and resins, which also are flammable (Brookhaven National Laboratory, 2004). During periods of above average temperatures and below average rainfall and humidity, high resin content (which increases ignition potential, flammability, and fire intensity) and rapid drying rates, can result in extreme fire dangers. Pitch pines are able to survive most fires due to their thick, insulating bark and ability to rapidly sprout from buds in the trunk and root collar. The Central Pine Barrens contains one of the greatest concentrations of endangered, threatened, and special concern plant and animals species in NY and provides recharge to the aquifer from which Long Island draws significant portions of its drinking water. There are approximately 1,000 annual wildfires in the Central Pine Barrens; as many as 75 brush fires may occur on a spring day. Over 95 percent of these fires are estimated to be anthropogenic (started by humans), including both accidental fires and arson. On the east coast of the United States, wildfires ignited by lightning are less frequent than in the west because lightening in the east is generally accompanied by rainstorms. Figure 5-189 on the following page shows the boundaries of those fire districts serving the Central Pines Barrens. The 17 fire districts whose jurisdiction includes some portion of the Core Preservation Area of the Central Pine Barrens (as defined by the State) include: DM~ ~000 Hazard Mitigation Plan 2 SUffolk c~untyl New York DRAFT - September 2007 5.4.10-4 SECTION 5.4.10: RISK ASSESSMENT - WILDFIRE · Brookhaven Fire District · East Quogue Fire District · Eastport Fire District · Flanders Fire District · Gordon Heights Fire District · Hampton Bays Fire District · Manorville Fire District · Middle Island Fire District · Miller Place Fire District Source: Central Pine Barrens Wildfire Task Force, 1999.

These areas include Edgewood Oak Brush Plains, Connetquot River, Sayville Grasslands, Conscience Point, Mashomack Preserve and Montauk Peninsula (Figure 5-192). Figure 5-192. Fire Dependent Conservation Areas on Long Island Source: The Nature Conservancy Wildfire Assessment Tools There are several tools available to estimate fire potential, danger and growth including the United States Department of Agriculture (USDA) Forest Service's Wildland Fire Assessment System (WFAS), and the Haine's Index. Wildland Fire Assessment System (WFAS) The WFAS is an intemet-based information system that provides a national view of weather and fire potential, including national fires danger, weather maps and satellite-derived "Greenness" maps (Burgan et. al., 1997), The USDA Forest Service created the WFAS Fire Danger Rating level system that compiles and evaluates data including current and antecedent weather, fuel types, and moisture content (for both live and dead fuel). The WFAS Fire Danger Rating is a descriptive coding system that allows fire managers from across the country to evaluate and describe the fire danger in their area (Table 5-57). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.10-8 SECTION 5.4.t0: RISK ASSESSMENT - WILDFIRE Table 5-57. Wildland Fire Assessment System Fire Dan~er Ratin~ and Color Code SFstem Fuels do not ignite readily from small firebrands although a more intense heat source, such as lightning, may start fires in duff or punky wood. Fires in open cured grasslands may burn freely a few hours after rain, but woods fires spread slowly by creeping or smoldering, and burn in irregular fingers. There is little danger of spotting. Moderate (M) (Light Green or Blue) High (H) (Yellow) Very High (VH) (Orange) Fires can start from most accidental causes, but with the exception of lightning fires in some areas, the number of starts is generally Iow. Fires in open cured grasslands will burn briskly and spread rapidly on windy days. Timber fires spread slowly to moderately fast. The average fire is of moderate intensity, although heavy concentrations of fuel, especially draped fuel, may burn hot. Short-distance spotting may occur, but is not persistent. Fires are not likely to become serious and control is relatively easy. All fine dead fuels ignite readily and fires start easily from most causes. Unattended brush and campfires are likely to escape. Fires spread rapidly and short-distance spotting is common. High-intensity burning may develop on slopes or in concentrations of fine fuels. Fires may become serious and their control difficult unless they are attacked successfully while small. Fires start easily from all causes and, immediately after ignition, spread rapidly and increase quickly in intensity. Spot fires are a constant danger. Fires burning in light fuels may quickly develop high intensity characteristics such as tong-distance spotting and fire whirlwinds when they burn into heavier fuels. Fires start quickly, spread furiously, and burn intensely. All fires are potentially serious. Development into high intensity burning will usually be faster and occur from smaller fires than in the very high fire danger class. Direct attack is rarely possible and may be dangerous except immediately after ignition. Fires that develop headway in heavy slash or in conifer stands may be unmanageable while the extreme burning condition lasts. Under these conditions the only effective and safe control action is on the flanks until the weather changes or the fuel supply lessens. Source: (Wildland Fire Assessment System, 2007) The WFAS provides the Observed Experimental Fire Potential map daily on their website. The experimental fire potential index map uses satellite derived relative greenness, a National Fire Danger Rating (NFDR) fuel model map (both I km resolution), and an interpolated 10-hour timelag map as inputs to weight the relative influence of live and dead vegetation to fire potential. The scale ranges from 0 (Iow) to 100 (high). Except for 10-hour moisture content, the calculations used in the NFDR System are not part of the Fire Potential Index. The U.S. Fish and Wildlife Service operates an automated weather station on the south shore of Long Island and monitors NFDR data. The Central Pine Barrens Commission operates an automated fire weather station in Eastport. Based on data taken from this site, the Commission sends notifications during the work week of the daily fire danger weather rating to all fire departments and fire management personnel. Until recently, the 2pm data, including Keetch-Byram Drought Index (KBDI), included in these afternoon reports. Alerts are issued during periods of"high" or "extreme" fire conditions. Figure 5-193 shows an example of an Observed Experimental Fire Potential Map and 10-Hour Fuel Moisture Map developed by the WFAS. Ten-hour fuel moisture of less than 7 percent is considered very dry, presenting a potential for high fire intensity which could result in crown fires.

According to the Wildland Fire Assessment System website, "dead fuel moisture responds solely to ambient environmental conditions and is critical in determining fire potential." The 1000-hr FM represents the modeled moisture content in dead fuels in the 3 to 8 inch diameter class and the layer of the forest floor about four inches below the surface. The 1000-hr FM value is based on a running 7-day computed average using length of day, daily temperature and relative humidity extremes (maximum and DMA 2000 H~icl ~itigation Pian 2 Suffolk c0uniyl New Y0;k 5.4.10-10 DRAFT - September 2007 SECTION 5.4.10: RISK ASSESSMENT - WILDFIRE minimum values) and the 24-hour precipitation duration values (Northern Rockies Coordination Center, Date Unknown).

According to the Wildland Fire Assessment System website, the KBD1 "...value represents the net effect of evapotranspiration and precipitation in producing cumulative moisture deficiency in deep duff and upper soil layers. It is a continuous index, relating to the flammability of organic material in the ground. The KBDI attempts to measure the amount of precipitation necessary to i'eturn the soil to full field capacity. It is a closed system ranging from 0 to 800 units and represents a moisture regime from 0 to 8 inches of water through the soil layer. At 8 inches of water, the KBDI assumes saturation. Zero is the point of no moisture deficiency and 800 is the maximum drought that is possible. At any point along the scale, the index number indicates the amount of net rainfall that is required to reduce the index to zero, or · saturation. The inputs for KBDI are weather station latitude, mean annual precipitation, maximum dry bulb temperature, and the last 24 hours of rainfall. Reduction in drought occurs only when rainfall exceeds 0.20 inch (called net rainfall)" (Wildland Fire Assessment System, 2007). Figure 5-196 illustrates the KBDI for the U.S. on July 18, 2007.

Keetch-Byram Drought Index for the United States Keetch-Byram Drought Index: l$-J~3L-07 Source: (Wildland Fire Assessment System, 2007) Haines Index The Haines Index, also known as the Lower Atmosphere Stability Index, is used to indicate the potential for wildfire growth by measuring the stability and dryness of the air over a fire (Wildland Fire Assessment System, 2007). It is calculated by combining the stability and moisture content of the lower atmosphere into a number that correlates well with large fire growth. This index has been shown to be correlated with large fire growth on initiating and existing fires where surface winds do not dominate fire behavior. The Haines Index can range between 2 and 6. The drier and more unstable the lower atmosphere is, the higher the Haines Index rating. Suffolk County Fire Weather Danger Rating Data on fire weather, an important tool for both the prevention and suppression tactics for wildfires, is available to the local fire departments through Suffolk County Fire Rescue's Communication Center. A qualitative daily fire weather danger rating for Suffolk County is currently calculated by an interagency committee, based upon two fire weather stations, one operated by the US FWS at the Wertheim National Wildlife Refuge and one operated by the Central Pine Barrens Commission in Eastport. The daily Suffolk County fire weather danger rating is given as one of four values: "Low", color coded as Green, · "Moderate", color coded as Blue, · "High", color coded as Yellow, or · "Extreme", color coded as Red. The daily fire weather danger rating indicates how fire will behave in the Central Pine Barrens areas; it does not predict the possibility of fire occurring. This fire weather index is currently utilized to notify the public when fire behavior potential roaches levels of concern that require special caution in the outdoors. This data is also used by the Federal, State and County Park officials in coordination with local officials when making decisions about restricting or prohibiting use of fire and other activities at parks and other public lands in the interest of public safety. [ DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.10-12 DRAFT - September 2007 SECTION 5.4.10: RISK ASSESSMENT - WILDFIRE A CD-based GIS ]napping tool, called "Fire Atlas" developed by the Long Island Chapter of The Nature Conservancy (TNC) is available to members of the Pine Barrens Commission, emergency responders, land managers, and local and state officials. This free tool consolidates valuable data for responders and decision-makers to support fire prevention, response planning, and emergency response. Data within the Fire Atlas includes hydrant locations, roads, access points, political boundaries, airports, vegetation species and cover types, fuels, water sources, wetlands, and soil types. Previous Occurrences alld Losses Impacts to human health and safety and property from major urban fires are often severe and direct. Fires have significant community-wide impacts, especially when lives and homes are impacted. Fires can also have significant economic impacts, especially if major transportation routes are closed. The short-term effects of wildfires can include destruction of timber, forest, wildlife habitats, scenic. vistas, and watersheds. Business and transportation disruption also can occur in the short term. Long- term effects can include reduced access to recreational areas; destruction of community infrastructure; and cultural and economic resources (USGS, 2006). Several sources of historic wildfire statistics for NY and Suffolk County indicate that the previous occurrences and losses make the wild fire hazard a notable hazard of concern. The National Interagency Fire Center (NIFC) reports that in 2006, 249 wildfires burned a total of 2,508 acres across the State. The University of South Carolina's Spatial Hazard Events and Losses Database for the U.S. (SHELDUS) reports four significant wildfire disasters in Suffolk County from 1960 to the present, including fires in April 1962, August 1980, August 1995, and May 2001. None of these four fires resulted in human fatalities (SHELDUS, 2007). Additional research through agencies and stakeholders including local fire agencies, state resources, and the Long Island Chapter of The Nature Conservancy (TNC) provides a more complete picture of historic wildfires in Suffolk County. Figure 5-197 illustrates some of the locations of well-documented historic wildfires on Long Island and concentrated in the Central Pine Barrens area. Table 5-58 provides a summary of significant wildfire events across the County as collected from multiple sources. Loss data for these wildfires are reported in the general information description, as available.

Every volunteer fire department on Lon9 Island as well as paid departments and additional crews from New Jersey, FDNY and Connecticut joined forces to control the wall of flames that leapt over the four-lane Sunrise Highway-- and the trucks trying to stop it--and charged toward a housing development. Experts predicted that all of Westhampton Beach could be lost; the flames threatened hundreds of homes and thousands of people, and ultimately burned more than 5,000 acres on both sides of Sundse Highway, Firefighters brought the fire under control after a weekdoog battle, but not a single structure was completely destroyed, and there were no fatalities or serious injuries, fl became the largest wildfire on Long Island in recent history. Is the all the same "event" - ? The summer of 1995 was Long island's driest in 71 years. Pine and scrub oak forests in central Suffolk County were tinder dry and ready to explode into flame. On August 21, an 1,800-acre fire, believed to be caused by human activity, started at DEC's Rocky Point Natural Resoumes Management Area..Three days later, the Sundse Fire began. With flames from 50-to 200-feet high. it threw burolng embers 400 feet across Sundse Highway, ultimately burning 3,200 acres. By August 27, beth fires were extinguished, Firefighters from virtually every fire department on Long Island, along with county, state and federal personnel, responded to the call. In the end, this force of 2,500 strong saved more than 150 structures in the path of the Sunrise Fire. More than 2,500 people responded to the 1995 fires on Long Island, including 2,000 fireflghters from 192 fire and ambulance companies all across Long Island, New York City and Connecticut. Thirty-eight DEC forest rangers provided on~ground wildlaed fireflghting expertise and aviation support for helicopter bucket drops. Two hundred members of the U.S. Forest Service's "hotshot" crews and fire management sta~ came. Pilots from the U.S, Military Academy at West Point and the New York Army National Guard also fought the blaze. Today, you can still see the tree skeletons from the fires of 1995, but the rapidly growing new vegetation is creating healthy and rejuvenated pine barrens. Pitch-pine, scrub-oak barrens are among the most endangered natural communities in the country. They support many uncommon plants and animals, including the globally rare dwarf pitch pine.

As of the date of this draft plan, no estimate has been made regarding damages or acreages burned. Nine hundred Long Island Power Authority customers lost power thanks to the Deer Park blaze. A bn~sh~re scorched up to 50 acres in western Suffolk County on Apd119, wreaking havoc on the roads and rails, knocking out power to homes, and sending a plume of smoke into the air that could be seen for miles. The fire started in Deer Park and spread rapidly into Brentwood, moving in different directions, It took 43 6re companies from Nassau and Suffolk County to battle the blaze, which raged for more than four hours. Traffic was snaded, service on the Long Island Rail Road (LIRR) was interrupted, and hundreds of residents lost power. The cause of the Maze, which broke out about 1:30 p.m. in the Edgewood Oak Brush Plains Preserve (largest remnant of pitch pine scrub oak on Long island) near the Deer Park LIRR station and the Heartland Industrial Park, is under investigation. Brentwoed Fire Chief Bill Winning noted that dry conditions made the area more susceptible to fire. Although officials considered this event as one fire, it had to be fought on three fronts because of high winds that allowed it to spread quickly. Two buildings in the industdut park were evacuated, he said, but no property was dam'aged by the fires and workers were eventually allowed to return. The Long Island Power Authority (LIPA), at the request of the Deer Park Fire Department. shut off electricity in the area of the fire to protect both emergency workers on the scene and local residents As a result, about 900 residents temporarily lost power. Two Brentwood flrefighters were injured. A number of highways were closed, including the Sagtikos Parkway, Pine Aire Drive, and Long Island Avenue.

DMA 2000 H~aid ~iiigation Plan - Suffolk County, ~e~ Yo;k 5.4.10-17 DRAFT - September 2007 SECTION 5.4.10: RISK ASSESSMENT - WILDFIRE Probabilit.~ of Future Events It is difficult to predict the likelihood of wildfires in a probabilistic manner, such as "there will be a catastrophic wildfire once every X number of years.' This is because a number of variable factors impact the potential for a wildfire to occur and because some conditions (for example, ongoing land use development patterns) exert increasing pressure on the WUI zone. Based on available data, the wildfire hazard will continue to present a risk. Given the numerous factors that can impact wildfire potential, the likelihood of a wildfire event starting and sustaining itself should be gauged by professional fire managers on a daily basis using the methods and tools described above. Earlier in this section, the identified hazards of concern for ~ Suffolk County were ranked. The NYS Hazard Mitigation Plan conducts a similar ranking process for hazards that affect the State. The probability of occurrence, or likelihood of the event, is one parameter used in this ranking process. Based on historical .records and input from the Planning Committee, the 15 probability of occurrence for wildfire events in the County is considered moderate. ~ VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. The following text evaluates and estimates the potential impact of the wildfire hazard on SC including: · Overview of vulnerability · Data and methodology used for the evaluation · lmpact, including: (1) impact on life, safety and health of SC residents, (2) general building stock, (3) critical facilities, and (4) economy · Further data collections that will assist understanding of this hazard over time · Overall vulnerability conclusion Overvie~ of Vulnerability Wildfire hazards can impact significant areas of land, as evidenced by wildfires throughout the United States over the past several years (e.g., New Jersey this past spring experienced a 13,000+ acre wildfire that destroyed homes and closed major roadways). Fire in urban areas has the potential for great damage to infrastructure, loss of life, and strain on lifelines and emergency responders because of the high density of population and structures that can be impacted in these areas. Wildfire, however can spread quickly, become a huge fire complex consisting of thousands of acres, and present greater challenges for allocating resources, defending isolated structures, and coordinating multi-jurisdictional response. If a wildfire occurs at a WU1, it can also cause an urban fire and in this case has the potential for great damage to infrastructure, loss of life, and strain on lifelines and emergency responders because of the high density of population and structures that can be impacted in these areas. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.10-18 DRAFT - September 2007 SECTION 5.4.10: RISK ASSESSMENT - WILDFIRE Data m~d Methodolng~ Information regarding the wildfire hazard included input and data from the Planning Committee, the Central Pine Barrens Wildfire Task Force, TNC, Brookhaven National Laboratory, FEMA, NOAA's NCDC databases, USGS, USFWS, National lnteragency Fire Center, and other sources of documentation for this area. In]pact on Life, Health aud Safety, General Building Stock, Critical Facilities and the Economy As demonstrated by historic wildfire events in SC (e.g., 1995 Sunrise Fires) and other parts of NYS and the country), potential losses include human health and life of residents and responders, structures, and natural resources. In addition, wildfire events can have major economic impacts on a community from the initial loss of structures and the subsequent loss of revenue from destroyed business and decrease in tourism. For wildfire, the Central Pine Barrens is identified as the largest hazard area of concern. Additionally, The Nature Conservancy has identified several other wildfire hazard areas in SC including Edgewood Oak Brush Plains, Connetquot River, Sayville Grasslands, Conscience Point, Mashomack Preserve and Montauk Peninsula (Figure 5-192). Therefore, all assets in, and adjacent to the WUI zone around these hazard areas of concern, including population, structures, critical facilities, lifelines, and businesses, as described in the County profile section (Section 4), are considered vulnerable to wildfire. Table 5-59 provides the estimated parcel status by ownership and land use for the Core Preservation Area in the Central Pine Barrens. The areas and resources identified here are considered vulnerable to the damages from wildfire. Table 5-59.

Notes: Land use codes are from the Property Type Classification and Ownership Codes produced by the State Board of Equalization and Assessment (Albany, NY, 1990; now known as the Office of Real Property Services). Actual built roadways are not included in the above data, as they are not assigned tax .map parcel numbers or acreages. It is estimated that there may be approximately 3,000 acres of such roads in the core area. For the purposes of this Plan, all structures in the WUI zone are at some risk of being destroyed or seriously damaged by a wildfire; however, strong fire suppression, management, and response planning systems are in place. Due to insufficient data, a full quantitative loss estimate was not completed for the wildfire hazard. The Central Pine Barrens Wildfire Task Force indicates that wildfires damage hundreds, sometimes thousaads, of acres in the Pine Barrens each year. These fires jeopardize homes and businesses in the wildland-urban interface. These fires cost thousands of taxpayer dollars to suppress and control and involve hundreds of operating hours on fire apparatus and thousands of volunteer man hours from the volunteer firefighters. There are also many direct an.d indirect costs to local businesses that excuse volunteers from work to fight these fires. These fires often cause injury to both civilians and firefighters and may cause damage to structures as well (Central Pine Barrens, 2007). It is recognized that a number of critical facilities, transportation and utility assets are located in the Central Proc Barrens, and may be vulnerable to the throat of wildfire. Of particular note, the Long Island Exprcssx~ay and the Long Island Railroad are two major east-west transportation arteries that were closed during Irc 1995 wildfires. Additional Data and Next Steps Data regarding the construction of structures in the study area, such as primary building materials used (e.g.. x~ood versus brick, fire detection equipment, age, etc.), proximity to fast burning/high intensity vegetatixe communities (for example, Pitch Pine, Scrub Oak), and availability of fire suppression infrastracturc should be identified for further evaluation. Several entities with ongoing wildfire management responsibilities in Suffolk County should be involved with any future data collection and analysis. These include the Central Pine Barrens Wildfire Task Force, The Nature Conservancy, DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 5.4.10-20 ~i DRAFT - September 2007 SECTION 5,4,10: RISK ASSESSMENT - WILDFIRE Brookhaven National Laboratory, the 17 local fire jurisdictions through the Suffolk County Fire ChieFs Council and Fire District Managers' Association, Suffolk County Office of Emergency Management and Fire Rescue & Emergency Services, New York State Department of Environmental Conservation Wildfire & Incident Management Academy, and NYSEMO. Development and availability of such data would permit a more detailed estimate of potential vulnerabilities, including loss of life and economic damages, based on the population and resources exposed to the hazard. WUI planning should include ongoing efforts to: · Identify and map structures, resources, and property that require protection · Use satellite imagery to create land cover and vegetation community maps outside of the legal boundary of the Central Pine Barrens · Create land use regulations that encourage construction of defensible space and shaded fuelbreaks · Create land use regulations that require firewise construction in the WUI · Reduce fuel and create shaded fuel-breaks (including a combination of mechanical thinning and prescribed fire) · lnclude public education campaigns 'to spread information to citizens at risk The FEMA fuel model maps do not provide sufficient information to refine the exposure assessment conducted above or to adequately specify the WUI areas in relation to the built (vulnerable) environment. Such data should be developed over time given the localized threat from the wildfire hazard in the Central Pine Barrens area. Overall Vulnerability Assessment Buildings constructed of wood or vinyl siding are generally more likely to be impacted by the fire hazard than buildings constructed with bricks or concrete. While it is not possible to predict when and where a fire will start, the local fire departments are well-equipped and prepared to respond to fires as they arise. Large-scale wildfires with causing wide-spread damage are considered likely to occur in the area at some point in the future due to the nature of the vegetative community, fluctuating climate conditions, and increased pressures on the WUI zone. The status of fire risk in the County will continue to be monitored and ongoing and new mitigation efforts to prevent fires and control them when they arise will continue to be developed. The overall hazard ranking for SC as determined by the Planning Committee for this hazard is low (see Tables 5-6 and 5-7). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.10-21 SECTION 5.4.1 1: RISK ASSESSMENT- DROUGHT 5.4.1 1 DROUGHT This section provides a profile and vulnerability assessment for the drought hazard. IIAZARI) PROFI I,E This section provides profile information including: description, location and extent, previous occurrences and losses, and the probability of future occurrences. Description The National Weather Service (NWS) Climate Prediction Center (CPC) defines drought as a deficiency of moisture that results in adverse impacts on people, animals, or vegetation over a sizeable area. According to the NYS HMP, drought is a normal, recurrent feature of climate. It occurs almost everywhere, although its features vary from region to region. Defining drought is therefore difficult; it depends on differences of regions, water supply needs, and disciplinary perspectives. In general, drought originates from a deficiency of precipitation over an extended period of time, resulting in a water shortage for some activity, group, or environmental sector (NYSEMO, 2004). Other climatic factors, such as high temperatures, prolonged high winds and low relative humidity, can aggravate the severity of a drought. These conditions are caused by anomalous weather patterns when shifts in the jet stream block storm systems from reaching an area. As a result, large high-pressure cells may dominate a region for a prolonged period, thus reducing precipitation. This natural hazard differs from other hazards in several ways. First, there is no universally accepted definition of drought. Second, drought onset and recovery are usually slow. Third, droughts can impact a much larger area and last many times longer than most other natural hazards. Fourth, droughts historically have occurred as are part of the natural variability of weather patterns. Due to these differences, many communities have neglected to include this hazard in their disaster management plans (ICLR, 2005). According to FEMA and the NWqS, there are four different ways that drought can be defined or grouped: · Meteorological - a measure of departure of precipitation from normal. It is defined solely on the degree of dryness. Due to climatic differences, what might be considered a drought in one location of the country may not be a drought in another location. · Agricultural - refers to a situation where the amount of moisture in the soil no longer meets the needs of a particular crop. It is defined in terms of soil moisture deficiencies relative to water demands of plant life, primarily crops. · Hydrological - occurs when surface and subsurface water supplies are below normal. It is related to the effects of precipitation shortfalls on streamflows and reservoir, lake and groundwater levels. · Socioeconomic - refers to the situation that occurs when physical water shortages begin to affect people. It associates the supply and demand of economic goods or services with elements of meteorologic, hydrologic and agricultural drought. This drought type occurs when the demand for water exceeds the supply as a result of a weather related supply shortfall (NWS, Date Unknown). According to the NYS HMP, drought produces an array of impacts that span many sectors of the economy and reach beyond the areas that experience the physical drought. This complexity exists DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT- September 2007 5.4.11-1 SECTION 5,4.11: RISK ASSESSMENT - DROUGHT because water is integral to our ability to produce goods and provide services. Direct impacts of drought (e.g., reduced crops, increased fire hazards, reduced water levels, damage to wildlife and fish habitat) have cascading indirect impacts (e.g, reduced income from a lack of crop production, increased prices due to a crop shortage, unemployment). The many impacts of drought can be listed as economic, environmental, or social. Economic impacts occur in agriculture and related sectors because of the reliance of these sectors on surface and subsurface water supplies. Environmental impacts are the result of damage to plant and animal species, wildlife habitat, and air and water quality, forest and grass fires, degradation of landscape quality, loss of biodiversity and soil erosion. Social impacts involve public safety, health, conflicts between water users, reduced quality of life and inequities in the distribution of impacts and disaster relief. A summary of potential impacts associated with the drought hazard are identified in Table 5-60. This table includes only some of the potential impacts of drought. · Loss of national economic growth, slowing down of economic development · Damage to crop quality, less food production · Increase in food prices · Increased importation of food (higher costs) · Insect infestation · Plant disease · Loss from dairy and livestock production · Unavailability of water and feed for livestock which leads to high livestock mortality rates · Disruption of reproduction cycles (breeding delays or unfilled pregnancies) · Increased predation · Increased fire hazard - Range fires and Wildland fires · Damage to fish habitat, loss from fishery production · Income loss for farmers and others affected · Unemployment from production declines · Loss to recreational and tourism industry · Loss of hydroelectric power · Loss of navigability of rivers and canals Increased desertification - Damage to animal species Reduction and degradation of fish and wildlife habitat Lack of feed and drinking water Disease Increased vulnerability to predation. Loss of wildlife in some areas and too many in others Increased stress to endangered species Damage to plant species, loss of biodiversity Increased number and severity of fires Wind and water erosion of soils Loss of wetlands Increased groundwater depletion Water quality effects Increased number and severity of fires Air quality effects Food shortages Loss of human life from food shortages, heat, suicides, violence Mental and physical stress Water user conflicts Political conflicts Social unrest Public dissatisfaction with government regarding drought response Inequity iR the distribution of drought relief Loss of cultural sites Reduced quality of life which teads to changes in lifestyle Increased poverty Population migrations Source: ThinkQuest, Date Unknown Location and Extent Long Island is identified as NYS Department of Environmental Conservation (NYS DEC) Drought Management Region I (Figure 5-198).

NYS DEC Droti~ht Management Re~ions of NYS New York State Deparlment of Enx~ronmental Conservation ? V Drought R~gions ...... I Long Island New York State Drought Management Regions Source: NYS DEC, 2007 All of SC is susceptible to drought. Areas at particular risk include communities thflt rely on private wells for potable water supply; certain areas with elderly, impoverished, or otherwise vulnerable populations; and agricultural resources which require the abundant use of ample water supply to thrive. All of Long Island-from Queens to Montauk depends upon its groundwater for its drinking water. Most of SC is serviced by the non-profit SC Water Authority (SCWA), which is the largest public water supplier on Long Island. The SCWA operates the largest water system in the nation based entirely upon groundwater. Serving over 300,000 accounts and 1.2 million consumers, SCWA pumps nearly 44 billion gallons of potable water each year. Groundwater is pumped from 400 active wells in 180 well fields strategically located across SC's 85-mile long, 10 mile-wi&, 850-square mile area. On average, SC receives about 45 inches of rain per year with more than 900,000,000 gallons of water entering the aquifers on an average day. Even during the summer at peak usage, the SCWA rarely pumps out more than 400,000,000 gallons in a single day (SCWA, 2002). Severe drought conditions could reduce groundwater recharge and decrease the water supply for residential and agricultural users. According to the South Fork Groundwater Task Force, the SCWA water use rate increases annually, as development and the demand for water increases. This trend will not reverse itself. With more and more development taking place year after year, the demand on groundwater will become even greater, which increases the risk of potential hardships during drought events. Consumption of groundwater coupled with drought can lead to a variety of related problems (e.g., impacts to the natural resources of SC, such as lowering ponds and streams and negatively effecting wetlands). DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT- September 2007 5.411i:3 SECTION 5.4.1 1: RISK ASSESSMENT- DROUGHT As indicated by Charles Groat of USGS in February 19~ 2005, understanding water storage--both surface water and ground water storage--is critical in understanding the effects of climate variability. As surface- water storage beco]nes more limited, use of ground-water storage to modulate the effects of droughts increases in importance, as do potential enhancements by artificial recharge. If ground-water storage is large, droughts will have a small, if any, effect on long-term water storage in an aquifer system. In contrast, where ground-water storage has been substantially reduced by long-term withdrawals from wells, it ]nay be more limited as a source of water to help cope with droughts, which ]nay potentially be the case for SC. Fifty years of data were analyzed to show the effects of drought and changing water use and wastewater disposal on Long Island's ground-water system. Ground water from the upper glacial, Magothy, and Lloyd aquifers is used to supply water to nearly half of the 7.5million people on Long Island. Because of the long history of dependence on ground water, the USGS has collected hydrologic data on Long Island since the early 1900s. The network consists of over 600 wells throughout Long Island. These long-term hydrologic data show significant declining changes in water levels over the past 100 years. These changes are due to the changing history of water use in New York City and areas east, sewering, increased pumping and climate variation. Water-level declines from 1963 to 1967 are due to effects of the regional drought in the 1960s. In this urbanized area, ground-water withdrawal and urbanization mask water-level fluctuations associated with precipitation. This demonstrates the many factors that affect hydrologic processes and water availability throughout Long Island (Groat, 2005). SC is the largest aghcultuml county in NYS based on dollar value of product sales. SC has the largest'and fastest growing wine industry in the US, ranked second only to California in United States grape production. SC also has the state's largest horticultural sales and service industry. Towns within SC that include significant farmland include Southampton, Southold, Brookhaven and Riverhead. Agricultural resoumes need ample amounts of water for successful production; which not only relies on natural precipitation but also requires the supply and demand of groundwater resources, both which become limited or compromised during times of drought. According to FEMA, the extent (e.g., magnitude or severity) of drought can depend on the duration, intensity, geographic extent, and the regional water supply demands made by human activities and vegetation. The intensity of the impact from drought could be minor to total damage in a localized area or regional damage affecting human health and the economy. Generally, impacts of drought evolve gradually and regions of maximum intensity change with time. The severity of a drought is determined by areal extent as well as intensity and duration. The frequency of a drought is determined by analyzing the intensity for a given duration, which allows determination of the probability or percent chance of a more severe event occurring in a given mean return period. Drought is a recurring natural phenomenon characterized by its severity, duration and extent. It is therefore a three-dimensional phenomenon, which is difficult to assess. The wide variety of resources affected by drought, its diverse geographical and temporal distribution, and the many scales drought operates on make it difficult to develop either a definition to describe drought or an index to measure it. Many quantitative measures of drought have been developed in the United States, depending on the discipline affected, the region being considered, and the particular application. Several indices developed by Wayne Palmer [Palmer Drought Severity Index (PSDI) and Crop Moisture Index (CMl)], as well as the Standardized Precipitation Index (SPI), are useful for describing the many scales of drought. Other indices include accumulated departure from normal streamflows, low-flow frequency estimates and changes in water storage, groundwater levels and rates of decline, and lake levels. Some of the most commonly used indices to measure or identify the severity and classification of past and present droughts primarily includes, but not limited to, the following: NOAA-NCDC - Palmer Drought Severity Index (PDSI) / Crop Moisture Index (CMl): The PDSI developed in 1965, indicates the prolonged and abnormal moisture deficiency or excess. The CMl gives DMA 2000 Hazard Mitigaiion Plan 2 ~uff0ik c0uhiy, New York DRAFT - September 2007 5.4.11-4 SECTION 5,4.1 1: RISK ASSESSMENT- DROUGHT the short-term or current status of purely agricultural drought or moisture surplus and can change rapidly from week to week. The PDSI is an important climatological tool for evaluating the scope, severity, and frequency of prolonged periods of abnormally dry or wet weather. It can be used to help delineate disaster areas and indicate the availability of irrigation water supplies, reservoir levels, range conditions, amount of stock water, and potential intensity of forest fires. The CMl, developed in 1968, can be used to measure the status of dryness or wetness affecting warm season crops and field activities (NWS, 2005). The PDS1 was developed by Wayne Pahner in the 1960s and uses temperature and rainfall information in a formula to determine dryness. It has become the semi-official drought index. The PDSI is most effective in determining long term drought - a matter of several months - and is not as good with short-term forecasts (a matter of weeks). It uses a 0 as normal, and drought is shown in terms of minus numbers; for example, minus 2 is moderate drought, minus 3 is severe drought, and minus 4 is extreme drought. The PDS1 can also reflect excess rain using a corresponding level reflected by plus figures; i.e., 0 is normal, plus 2 is moderate rainfall, etc. (Table 5-61). The advantage of the PDSI is that it is standardized to local climate, so it can be applied to any part of the country to demonstrate relative drought or rainfall conditions. The negative is that it is not as good for short term forecasts, find is not particularly useful in calculating supplies of water retained in snow, so it works best east of the Continental Divide. The CMI is a formula that was also developed by Wayne Palmer subsequent to his development of the PDSI. The CMl responds more rapidly than the PDSI and can change considerably from week to week, so it is more effective in calculating short-term abnormal dryness or wetness affecting agriculture. CMl is designed to indicate normal conditions at the beginning and end of the growing season; it uses the same levels as the PDSI (NOAA, Date Unknown). Table 5-61. PSDI Classifications 4.0 or more extremely wet 3.0 to 3.99 very wet 2.0 to 2.99 moderately wet 1.0 to 1.99 slightly wet 0.5 to 0.99 incipient wet spell 0.49 to -0.49 near normal -0,5 to -0.99 incipient dry spell -1.0 to -1.99 mild drought -2.0 to -2,99 moderate drought -3.0 to -3.99 severe drought -4,0 or less extreme drought Source:Hayes, 2006 NOAA-NCDC U.S. Standardized Precipitation Index (SPI): While Palmer's indices are water balance indices [considering water supply (precipitation), demand (evapotranspiration) and loss (runoff}], the SPI is a probability index that considers only precipitation. The SP1 is based on the probability of recording a given amount of precipitation, probabilities are standardized so that an index of zero indicates the median preciPitation amount (half of the historical precipitation amounts are below the median, and half are above the median). The index is negative for drought and positive for wet conditions. As the dry or wet conditions become more severe, the index becomes more negative or positive. The SPI is computed by NCDC for several time scales, ranging from one month to 24 months, to capture the various scales of both short-term and long-term drought. D~ ?000 Hazard Miii~iion Piah ~olk County, NeW Yo;k' 5.4.11-5 DRAFT - September 2007 SECTION 5.4.11: RISK ASSESSMENT - DROUGHT National Drought MitiKation Center (NDMC) (University. of Nebraska / Lincoln) U.S. Drought Monitor: The NDMC helps people and institutions develop and implelnent measures to reduce societal vulnerability to drought, stressing preparedness and risk management rather than crisis management. Most of the NDMC's services are directed to state, federal, regional, and tribal governments that are involved in drought and water supply planning. The NDMC produces a daily drought monitor map that identifies drought areas and ranks droughts by intensity. U.S. Drought Monitor summary maps are available from May 1999 through the present and identify general drought areas and classification droughts by intensity ranging from DI (moderate drought) to D4 (exceptional drought). DO, drought watch areas, are drying out and possibly heading for drought, or are recovering from drought but not yet back to normal, suffering long-term impacts such as low reservoir levels (Table 5-62). The Drought Monitor is intended to provide a general and up-to-date summary of current drought conditions across the U.S., Puerto Rico, and U.S. Pacific territories. This monitor provides a "big picture" view for the general public, media, government officials, and others. To keep the map from becoming too complex, the drought categories shown represent typical drought intensities, not each drought intensity within an impacted area. The map is not designed to depict local conditions or to replace drought warnings and watches issued by local or regional govemment entities. Local or state entities may monitor different indicators than those used in the Drought Monitor to meet specific needs or to address local problems. As a consequence, there could be water shortages or crop failures within an area not designated as drought, just as there could be locations with adequate water supplies in an area designated as D3 or D4 (extreme or exceptional) drought. The Drought Impact Reporter is an interactive tool developed by the NDMC to collect, quantify, and map reported drought impacts for the United .States (and was used to identify known drought events throughout SC for this plan). The Drought Impact Reporter was created in response to the need for a national drought impact database. A risk management approach to drought management, which strongly emphasizes improved monitoring and preparedness, requires timely information on the severity and spatial extent of drought and its associated impacts. The information provided by the Drought Impact Reporter will help policy and decision makers identify what types of impacts are occurring and where (NDMC, Date Unknown). NOAA-NCDC North American Drought Monitor: The North America Drought Monitor (NA-DM) is a cooperative effort between drought experts in Canada, Mexico and the United States to monitor drought across the continent. The Drought Monitor concept was developed jointly by the NWS, the NDMC, and thc US Department of Agriculture's Joint Agricultural Weather Center in the late 1990s. This monitoring process synthesizes multiple indices, outlooks, and local impacts, into an assessment that best represents current drought conditions. The final outcome of each Drought Monitor is a consensus of federal, state and academic scientists. Maps of U.S. droughts are available from this source from 2003 to 2007 (N('DC, 2006). As presented by the NDMC, drought intensity categories are based on six key indicators and numerous supplementary indicators. Table 5-62 shows the indicators considered and ranges for each indicator based on dryness levels. Because the ranges of the various indicators often do not coincide, the final drought category tends to be based on what the majority of the indicators show. The analysts producing the map also weight the indices according to how well they perform in various parts of the country and at d i ffercnt times of the year. Additional indicators are often used in the West, where winter snowfall has a strong bearing on water supplies.

Previous Occurrences and Losses NYS is made up of 10 climate divisions, with SC located in the Coastal Climate Division (Division 4) (CCD). According to the NRCC, the NYS Coastal Climate Division has experienced numerous drought periods with a drought from 1965 to 1966 constituting the longest drought period on record.

Geological Survey Details regarding significant drought periods that have impacted SC include, but are not limited to, the following: DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 5.4.11-9 SECTION 5.4.11: RISK ASSESSMENT - DROUGHT 1962 through 1966 (4 year period): According to U.S. Geological Survey, Water-Resources Investigations Report 98-4069 "Simulation of the Effects of Development of the Groundwater Flow System of Long Island, New York," Long Island experienced a prolonged drought during this period. The decrease in surface and groundwater recharge from precipitation over this period caused many streams to reach their lowest recorded flows and ground water levels to decline by as much as 10 feet below the norm. The main stress on the groundwater system associated with the drought was the loss of recharge through the natural decrease in precipitation. The major hydrologic responses to the 1960% drought were changes in ground-water discharge to streams (baseflow)and declines in ground-water levels. The analysis focused on eastern Nassau and Suffolk Counties because water levels in western Long Island were being affected by development at this time. Base flow decreased noticeably in 1963 and, in most streams, had a maximum decrease of 25 to 60 percent. Streams with long channels that extend far inland (e.g., Nissequogue, Carlls, Connetquot Creeks,and Peconic River) showed the greatest seasonal variation and the greatest percent decrease in base flow during the drought because their headwaters lie close to the ground-water divide, where water-table declines are greatest. Stream headwaters are most vulnerable to large fluctuations in base flow and to drying up. Water level declines began in 1963 and accelerated in 1964 and 1965, when little water-level recovery occurred during the wet season. The largest total water table decline occurred at locations farthest from the shore and streams; drawdown near streams is typically subdued because streams provide a source of water. The maximum decline exceeded 10 feet near the Nassau-Suffolk County Border and 8 feet in central SC (Buxten and Smolensky, 2005). Figure 5-199. Maximum water table decline during the 1960's Drought A, MEASURED Source: Buxten and Smolensky, 2005 August - September 1995: Much of the Northeast and mid-Atlantic received little or no rain during this time period, exacerbating long-term dryness since mid-March 1995, and in some areas since October 1994. The severe short-term rainfall shortages enhanced a pattern of persistently subnormal precipitation dating back 6 to 11 months in much of the Northeast and mid-Atlantic. Most areas recorded less than 75% of nornlal precipitation, with localized sections of NY, lower New England, and the eastern mid- Atlantic observing under half of the normal precipitation. Typically, 16 to 23 inches of rain falls on the Northeast and eastern mid-Atlantic from March 12 to August 29, but only 10 to 15 inches was measured at most locations for the 17 l-day period in 1995. Rainfall was particularly short in eastern and southeastern NYS, northeastern Pennsylvania, and southern Vermont, where only 5 to 11 inches were reported. The long- term PSDI was rates as less than -4 ("extreme drought") over parts of central and southem NYS, southern Dk,l~ ~000 Hazard Mitigalion Plan - Suffolk Countyl New York DRAFT- September 2007 §.~31-i0 SECTION 5.4.11: RISK ASSESSMENT - DROUGHT Connecticut, northeastern Pennsylvania, and the eastern mid-Atlantic on August 26. which included SC (Figure 5-200). All of southeastern NYS was placed under a drought watch by Governor Pataki's Drought Management Task Force. The lack of rain on Long Island led to tinder dry conditions which aided the development of large wildfires, reportedly the worst in 60 years according to local officials. Two unusually large, severe wildfires, known as the "Rocky Point" and "Sunrise Fires", burned a total of 6,850 acres of the Central Pine Barrens over a 13 day period of this August - September 1995 drought. Forests were charred in Westhampton, Rocky Point, Calverton, and Medford, with a state of emergency in effect from August 24 until September 5, 1995. Burned areas included a portion of the globally rare dwarf pine plains. The wildfires were unusually severe and large because of extreme drought combined with increased winds and high fuel loads accumulated in the 65 years since the last major fire (Central Pine Barrens Wildfire Task Force, 1999). Nearly every fire department in Nassau and Suffolk Counties responded, along with several New York City departments and 32 federal, state, and local government agencies. Forty-nine firefighters were injured, none seriously. One house and five fire tracks were destroyed, and nine other houses plus the Westhampton train station were damaged (Blain, 1995). According to David Fischler, Commissioner of SC, (where the fires started) "weather was the dominant factor." According to Fischler, SC had a drought year (1995) consisting of 22 days with no rain and only 28 percent relative humidity, which is extremely low for SC. During this drought period, Mr. Fred Daniels, Deputy Commissioner of SC, indicated that in SC, during a summer day with drought conditions, it is not unusual to get many brush fires (Hafil, 1997). More information regarding this wildfire event is discussed earlier in this section (Section 5-4). Figure 5-200 shows a PDSI map of the U.S., including the study area.

DMA 2000 HaZaid Uiiig-~iio~ Plan ~ Suffolk C0uni~i New York DRAFT- September 2007 5.4.11-11 SECTION 5.4.t1: RISK ASSESSMENT - DROUGHT July - August 1999: 'According to NRCC, the drought of 1999 was one of the most significant weather events for the northeastern United States. This drought cuhninated during the summer months and was perhaps the most costly weather event of that year. The dry conditions that prevailed during the second half of 1998 were a prelude to 1999's drought. Between the months of July and December 1998, the Northeast received only 71% of the normal precipitation, its third driest such period on record. After a wet January, the months of February through August 1999 followed a similar pattern, accumulating only 76% of the normal precipitation, resulting in the 3rd driest such period in 105 years of recorded data. Precipitation deficits for the fourteen months ending in August 1999 ranged from 6 to over 14 inches across the region. By mid-July, severe drought was reported in parts of every state in the Northeast Region. Extreme drought was noted in parts of Delaware, Pennsylvania, New Jersey, and NYS between late July and early September. Drought emergencies with mandatory water restrictions were declared in Maryland, Delaware, New Jersey and Pennsylvania. The Clinton Administration declared counties in nine states (Connecticut, Kentucky, Maryland, New Jersey, NY, Ohio, Pennsylvania, Virginia and West Virginia) as agricultural drought disaster areas. Abundant rainfall during September (twice normal and the wettest on record) brought an end to drought concerns (Eggleston, 1999). Throughout the drought region, farmers took the hardest economic blow. Recreation and tourism industries and natural areas also were hard hit (e.g., parks, gardens and golf courses). On Long Island, 140,000 acres of parks and nature preserves were off limits until the drought eased (Crary, 1999). Monetary losses were not documented in the materials available for review. Mr. Michael Wyllie, a meteorologist with the NWS in Brookhaven, NY indicated that the drought in Long Island during this time period was one step below "extreme." The drought resulted in restrictions on water use, increased the danger of fire, and farmland disaster areas. Fi ure 5-201.

Ms. Jessica Chittenden of NYS Department of Agriculture and Markets indicated in November 2002, that 55 Counties (including SC) were eligible for drought assistance. All NYS agricultural counties were declared primary disaster areas by the USDA (Chittenden, 2002). Figures 5-203 and 5-204 show drought maps associated with this drought event.

The NYS HMP includes a similar ranking process for hazards that affect the State. The probability of occurrence, or likelihood of the event, is one parameter used in this ranking process. Based on historical records and input from the Planning Committee, the probability of occurrence for drought events in the County is considered frequent [hazard event that occurs more frequently than once in 10 years (>10 ~/yr)] (see Table 5-3). VULNERABILITY ASSESSMENT To understand risk, a community must evaluate what assets are exposed or vulnerable in the identified hazard area. For the drought hazard, all of SC has been identified as the hazard area. Therefore, all assets in SC (population, structures, critical facilities and lifelines), as described in the County Profile section, are vulnerable to a drought. Assets at particular risk would include any open land or structures at located along the wildland/urban interface (WUI) that could become vulnerable to the wildfire hazard due to extended periods of low rain and high heat, usually associated with a drought. In addition, water supply resources could be impacted by extended periods of low rain. Finally, vulnerable populations could be .particularly susceptible to the drought hazard and cascading impacts due to age, health conditions, and 14mited ability to mobilize to shelter, cooling and medical resources. The following text evaluates and estimates the potential impact of the drought hazard on SC including: * Overview of vulnerability · Data and methodology used for the evaluation · Impact, including: (1) impact on life, safety and health of county residents, (2) general building stock, (3) critical facilities, and (4) economy · Further data collections that will assist understanding of this hazard over time · Overall vulnerability conclusion Overview of Vulnerability Essentially, all of SC is vulnerable to drought. However, areas at particular risk are: areas used for agrieultural purposes (farms and cropland), open/forested land vulnerable to the wildfire hazard, areas where communities rely on private water supply, and certain areas where elderly, impoverished or otherwise vulnerable populations are located. Potential drought impacts are agricultural, hydrologic and socioeconomic. Agricultural drought impacts are associated with soil moisture deficiencies relative to water demands of plant life/crops. Hydrological drought impacts are associated with the effects of insufficient precipitation (rain and snow) on surface and subsurface water supplies (e.g., reservoir and groundwater levels). Socioeconomic drought impacts are associated with the human health and business impacts that can occur when the demand for an economic good exceeds supply and shortages occur. For example, shortages in water supply can impact tourism due to high heat that make an area less desirable for recreation and deteriorate natural resources that are draws for tourists (NYS, 2004). DMA ~000 Hazard Miiigation Plan 2 Suffolk Couht~, Ne~ ~Ork DRAFT - September 2007 5.4.11-15 SECTION 5.4.11: RISK ASSESSMENT - DROUGHT Data and Methodology Data was collected from HAZUS-MH, USDA, NOAA NCDC, the County, and Planning Colmnittee sources. At the time of this draft HMP, insufficient data are available to model the long-term potential impacts of a drought on the County. Over time additional data will be collected to allow better analysis for this hazard. Available information and a preliminary assessment are provided below. Impact on Life, Health and Safety Droughts conditions can cause a shortage of water for human consumption and reduce local fire-fighting capabilities. The drought hazard is a concern because both public and private water supply soumes in SC are from local groundwater sources. As stated in the County Profile section, Long Island's groundwater system is a federally-designated "sole source" aquifer. Additionally, the area is also identified as a Primary Water Supply Aquifer by NYS Department of Health (1981) and NYS DEC'(1987) (USEPA, 2007). The total capacity of the aquifers underlying SC is about 70 trillion gallons. Precipitation is the sole source of all naturally occurring fresh groundwater on Long Island. Seasonal- or long-term fluctuations in precipitation volume and, thus, in recharge, are reflected by the water levels in all aquifers. According to the NYS HMP, groundwater and water storage facilities were below normal on Long Island during the November.2001 to January 2002 and April to October 2002 droughts. The dollar amount of damages associated with these droughts is documented as "unknown" (NYS, 2005). The NYS HMP also lists mental and physical stress as social impacts of a drought (NYS, 2005). The infirm, young, and elderly are particularly susceptible to drought and extreme temperatures, sometimes associated with drought conditions, due to their age, health conditions and limited ability to mobilize to shelters, cooling and medical resources. For the purposes of this HMP, the entire population in the County is vulnerable to drought events. Impact on General Building Stock and Critical Facilities No structures are anticipated to be directly affected by a drought and are expected to be operational during a drought event. However, droughts contribute to conditions conducive to wildfires. The Central Pine Barrens is a forested area of approximately 102,500 acres within the central and eastern portions of SC: this area has an extensive history and ongoing risk of frequent wildfire (Central Pine Barren Wildfire Task Force, 1999). Risk to life and property is greatest in those areas where forested areas adjoin urbanized areas (high density residential, commer~:ial and industrial) or WUI. Therefore, all assets in, and adjacent to, the WUI zone around the Central Pine Barrens, including population, structures, critical facilities, lifelines, and businesses are considered vulnerable to wildfire. 1111pact on Economy When a drought occurs, the agricultural industry is most at risk in terms of economic impact and damage. During droughts, crops do not mature leading to a lessened crop yield, wildlife and livestock are undernourished, land values decrease, and ultimately there is financial loss to the farmer (FEMA, 1997). In 2003, there were 34,000 acres of farmland in SC, encompassing approximately six (6) percent of the County. The County ranks 27th in NYS for the number of farms and 5ffh for land in farms. According to tile NY Agricultural Statistics Service, the average value of land and buildings per farm in 2002 was $920.960, with total production expenses being $176.4 million averaging $270,618 per farm. The United Statcs Census indicates 63 percent of the farm operators report farnfing as their principal occupation DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT- September 2007 5.4.11-16 sEcTION 5.4.11: RISK ASSESSMENT - DROUGHT (USDA NASS, accessed online 2007). Table 5-65 shows the acreage of agricultural land exposed to the dronght hazard. Table 5-65. Al~ricultural Land in Suffolk Can 645 [ 34,000 I 26,616 I 92= I I 4,6 4 Source: USDA NASS, accessed online 2007 In 2002, the market value of all agricultural products sold from SC farms was $201.2 million ($177.7 million in crop sales and $23.5 million in livestock), with total sales averaging $309,035 per farm (USDA NASS, Accessed online 2007). According to the SC Agricultural Protection Plan, the farm industry generates 8,000 jobs and adds another $214 million to the economy (Jones and Fedelem, 1996). In 2002, the leading agricultural products sold were nursery and greenhouse plants (71%), vegetables (12%), poultry and eggs (7%), fruits and nuts (5%), aquaculture products (4%), and other products (1%). SC is rafiked 1~t in NYS for nursery and greenhouse stock and aquaculture products (USDA NASS, Accessed online 2007). Table 5-66 shows the square-footage of nursery and greenhouse stock in 2002. Table 5-66.

The Long Island Farm Bureau's intemet site shows Long Island has the highest number of horses per capita in NYS and SC ranks 7th for equine inventory value in NYS (Long Island Fama Bureau, accessed online 2007). SC's agriculture also provides the landscape and scenic beauty that supports Long Island's tourism industry. The Long Island tourism industry generates over $1 billion in revenues annually (Long Island Farm Bureau, accessed online 2007). SC wineries contribute to local tourism in the County. SC has the largest premium wine industry of any county in the U.S., with the exception of California. Long Island wineries encompass 1,600 acres ofviniferous grapes and contribute $30 million annually to the economy (Long Island Farm Bureau, accessed online 2007). Historic data and current modeling tools are not available to estimate specific losses to tourism for the drought hazard. The 2002 drought, identified as the worst in over 100 years, ended late in the fall of 2002. All NY agricultural counties, including SC, were declared primary disaster areas and eligible for drought assistance (Chittenden, 2002). Specific monetary losses for SC were not found in reviewed documentation. If the average production (dollar value) per crop type could be identified on a per acre basis, loss estimates could be developed based on assumed percent damage that could result from a drought. If a drought impacted 40% of the agricultural products sold from SC farms, based on 2002 market values, this would be a loss of $80.48 million. This figure does not include how the tourism industry and local jobs are impacted. DMA 2000 Hazard Mitigation Plan - Suffoi~ County, New York DRAFT- September 2007 5.4.11-17 SECTION 5.4.11: RISK ASSESSMENT - DROUGHT A prolonged drought can have a serious economic impact on a comlnunity. Increased demand for water and electricity may result in shortages and a higher cost for these resources (FEMA, 2005; NYS, 2004). Industries that rely on water for business may be impacted the hardest (e.g., landscaping businesses). Even though most businesses will still be operational, they may be impacted aesthetically. These aesthetic impacts are most significant to the recreation and tourism industry. In addition, droughts in another area could impact the food supply/price of food for residents in the County. Additional Data and Next Steps For the revised plan, any additional information regarding localized concerns and past impacts will be collected and analyzed. This data will be developed to support future revisions to the plan. Mitigation efforts could include building on ex'isting NYS, SC, and local efforts. The lead State Agency for drought preparedness is the NYS DEC. Overall VulnerabiliD' Assessment Historic data available indicate that droughts can impact SC. Drought events can cause significant impacts and losses to the County's water supply and economy. The overall hazard ranking for SC determined by the Planning Committee for the drought hazard is "low" (Tables 5-6 and 5-7). The cascade effects of drought include increased susceptibility to the wildfire hazard, increased and thus shortages on local resources (i.e., water supply, electricity). Losses associated with the wildfire hazard are discussed earlier in this section. DMA 2000 H~Zard Mitigaiion Plan - Suffolk County, New York 5.4.11-18 DRAFT - September 2007 SECTION 6: MITIGATION STRATEGY SECTION 6: MITIGATION STRATEGY This section presents mitigation actions for SC to reduce potential exposure and losses identified as concerns in the Risk Assessment portion of this plan. The Planning Committee reviewed the Risk Assessment to identify and develop these mitigation actions, which are presented herein. This section includes: 1 ) Background and past mitigation accomplishments (2) General mitigation planning approach 13) Plan mitigation goals and objectives (4) Identification, analysis, and implementation of potential mitigation actions for each hazard (5) Proposed County-wide hazard mitigation actions This section addresses both mitigation actions that are specific to particular hazards, as well as those that apply to multiple hazards. Hazard mitigation reduces the potential impacts of, and costs associated with, emergency and disaster- related events. Mitigation actions address a range of impacts, including impacts on the population, property, the economy, and the environment. Mitigation ~ctions can include activities such as: revisions to and enforcement of building codes, revisions to land-use planning, training and education, and structural and nonstructural safety measures. BACKGROUND AND PAST ACCOMPLISHMENTS Although DMA 2000 does not require a discussio~ regarding past mitigation efforts, an overview of past efforts is provided as a foundation for understanding the mitigation goals, objectives, and actions outlined in this HMP. SC, through previous and ongoing hazard mitigation actions, has demonstrated that it is ' pro-active in protecting its physical assets and citizens against losses from natural hazards. Examples of previous and ongoing actions and projects include: All Towns and Villages participating in this Plan, participate in the NFIP, which requires the adoption of FEMA floodplain mapping and certain minimum construction standards for building within the floodplain. The Town of Babylon and the Village of Northport in the Town of Huntington participate in CRS. CRS is a voluntary program designed to reward participating jurisdictions for their efforts to create more disaster-resistant communities using the. principles of sustainable development and manugcment. To ensure critical assets and essential services maintain power during hazard events, through NYS grant funding, SC has invested in 22 backup generators. Currently, one unit is in service on Shelter Island and one on Fishers Island due to their remote locations. The remaining units are on stand-by at securc locations in SC and may be requested by any municipality to mitigate a disaster. SC Office of Emergency Management (OEM) participates on the New York Coastal Storm Planning Team. The New York Coastal Storm Planning Team is a multi-jurisdictional effort to examine neighboring county and transportation emergency plans. Other participants include NYC OEM, '~'eslchester County OEM, Nassau County OEM, NY Port Authority OEM, and the Metropolitan Transit Authority OEM. DMA 2000 Fl-~a~ Mitigation Plan 2 Suffolk C0uniyl New York DRAFT- September 2007 SECTION 6: MITIGATION STRATEGY SC FRES makes presentations regarding hurricane preparedness to local Chambers of Coimnerce, communities and civic associations across Suffolk County. During the late summer and fall periods approximately 20 25 presentations are given each month. In addition SC FRES attends public meetings with local political figures to emphasize preparedness, such as the ones that were recently held with Congressman Bishop. Several studies have been conducted in the past to examine natural hazards effecting SC including: o H2M High Groundwater Study, Vols. I - III. 1980 o Atlantic Coast of Long Island Fire Island Inlet to Montauk Point Reformulation Study o Hurricane Damage Mitigation Plan for the South Shore, October 1984 o Proposed Long Island South Shore Hazard Management Program, December 1989 o Narrow Bay Floodplain Protection and Hazard Mitigation Plan, April 1997 o Department of Defense, Department of the Army, Corps of Engineers. Intent to Prepare a Draft Impact Enviromnental Statement for a Proposed Hurricane and Storm Damage Reduction Project at the Village of Asharoken, Suffolk County, NY. January 16, 2002 The Governor's Coastal Erosion Task Force Final Report II identifies previous investigations, past actions and associated costs, and recommendations to address coastal erosion along the Atlantic shoreline. These past and ongoing actions have contributed to the County's understanding of its hazard preparedness and future mitigation action needs, costs, and benefits. These efforts provide a foundation for the Planning Committee to use in developing this HMP. GENERAL MITIGATION PLANNING APPROACH The general mitigation planning approach used to develop this plan is based on the FEMA publication, Developing the Mitigation Plan: Idenn'fying Mitigation Actions and Implementing Strategies (FEMA 386-3) and input provided by NYSEMO. The FEMA document and NYSEMO guidance include four steps, which were used to support mitigation planning. These steps are summarized below and presented in more detail in the following sections. Develop mltlgatlon goals and objectives: Mitigation goals were developed using the hazard characteristics, inventory, and findings of the risk assessment, and through the results of the public outreach program. By reviewing these outputs and other municipal policy documents, objectives tying to these overarching goals were identified and characterized into similar themes. Identify and prioritize mitigation actions: Based on the risk assessment outputs, the mitigation goals and objectives, existing literature and resources, and input from the participating entities, alternative mitigation actions were identified. The potential mitigation actions were qualitatively evaluated against the mitigation goals and objectives and other evaluation criteria. They were then prioritized into three categories: high, medium, and low. FEMA defines Goats as general guidelines that explain what should be achieved. Goals are usually broad, long-term, policy statements, and represent a global vision. FEMA defines Objectives as strategies or implementation steps to attain mitigation goals. Unlike goals, objectives are specific and measurable, where feasible. FEMA defines Mitigation Actions as specific actions that help to achieve the mitigation goals and objectives. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 6-2 SECTION 6: MITIGATION STRATEGY Prepare an implementation strategy: High priority mitigation actions are recommended for first consideration for implementation, as discussed under each hazard description in the following sections. However, based on community-specific needs and goals and available funding and costs, some low or medium priority mitigation actions may also be addressed or could be addressed before some of the high priority actions. · Document the mitigation planning process: The mitigation planning process is documented throughout this Plan. Guiding Principle, Mitigatiou Goals aud Objectives This section presents the guiding principl~ for this l~lan, and mitigation goals and objectives identified to reduce or avoid long-term vulnerabilities to the identified hazards. Mission Statement Per FEMA guidance (386-1), a mission statement or guiding principle describes the overall duty and purpose of the planning process, and serves to identify the principle message of the plan. It focuses or constrains the range of goals and objectives identified. This is not a goal because it does not describe outcomes. SC's mission statement is broad in scope, and provides a direction for the Plan. The mission statement for the SC Plan is as follows: Identify and reduce the wdnerability to natural hazards in order to protect the health, safeO~, quali~, of life, environment and economy of the communities within Suffolk CounO~. Goals and Objectives According to CFR 201.6(c)(3)(i): "The hazard mitigation strategy shall include a description of mitigation goals to reduce or avoid long-term vulnerabilities to the identified hazards." The Planning Committee developed mitigation goals and objectives based on the risk assessment results, discussions, research, and input from amongst the committee, existing authorities, polices, programs, resources, stakeholders and the public. The Planning Committee identified eight goals through a facilitated exercise, working from a catalog of goal statements created through review of similar plans and FEMA planning guidance. Once the goals were established, objectives that meet multiple goals were selected through a similar facilitated exercise. For the purposes of this Plan, goals are defined as follows: Goals are general guidelines that explain what is to be achieved. They are usually broad, long-term, policy-type statements and represent global visions. Goals help define the benefits that the Plan is trying to achieve. The success of the Plan, once implemented, should be measured by the degree to which its goals have been met (that is, by the actual benefits in terms of hazard mitigation). The following are the mitigation goals for the SC Plan: · Gl - Save lives and reduce injury. · G2 - Avoid, minimize or reduce damage to property including but not limited to critical facilities, infrastructure and those properties known to receive or experience repetitive damages. [ DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 6-3 DRAFT - September 2007 SECTION 6: MITIGATION STRATEGY · G3 - Reduce ~xposure to risk, while protecting or restoring natural processes to the maximum extent possible. · G4 - Consider the wise uses of land in known or identified hazard areas. · G5 - Encourage the development and implementation of long-term, cost-effective and environmentally sound mitigation projects. · G6 - Promote hazard mitigation awareness and education throughout the county. · G7 - hnprove community emergency management capability (i.e., prepare, respond, recover, mitigate). · G8 - Maintain economic viability after a hazard event. SC goals are compatible with the needs and goals expressed in other available community planning documents as well as the NYS HMP. Each goal has a number of corresponding objectives that further define the specific actions or implementation steps. Achievement of these goals will define the effectiveness of a mitigation strategy. The goals also are used to help establish priorities. Objectives were then developed and/or selected by the Planning Committee through its knowledge of the local area, review of past efforts, findings of the risk assessment, qualitative evaluations, and identification of mitigation options. The objectives are used to 1 ) measure the success of. the Plan once implemented, and 2) to help prioritize identified mitigation actions. For the purposes of this Plan, objectives are defined as follows: Objectives are short-term aims which, when combined, form a strategy or course of action to meet a goal. Unlike goals, objectives are specific and measurable. The Planning Committee selected objectives that would meet multiple goals, as listed in Table 6-1. The objectives serve as a stand-alnne measurement of a mitigation action, rather than as a subset of a goal. Achievement of the objectives will be a measure of the effectiveness of a mitigation strategy. The objectives also are used to help establish priorities. Table 6-1.

Suffolk County Capabilit~r Assessment According to FEMA 386-3, a capability assessment is an inventory of a community's missions, programs and policies; and an analysis of its capacity to carry them out. This assessment is an integral part of the planning process. It identifies, reviews and analyzes local and state programs, polices, regulations, funding and practices currently in place that may either facilitate or hinder mitigation. A capability assessment was prepared by SC and each participating jurisdiction. The jurisdiction-specific capability assessments are presented in Section 9, Volume 2 of this Plan as part of their jurisdictional annex (Section 9). By completing this assessment, SC learned how or whether they would be able to implement certain mitigation actions by determining the following: · Types of mitigation actions that may be prohibited by law; · Limitations that may exist on undertaking actions; and · The range of local and/or state administrative, programmatic, regulatory, financial and technical resources available to assist in implementing their mitigation actions. Table 6-2 presents legal and regulatory capabilities. Table 6-3 presents the administrative and technical capabilities. Table 6-4 presents fiscal capabilities, and Table 6-5 presents the community classifications for SC.

Strengths, Weaknesses, Opportunities and Obstacles (SWO0) On July 26, 2007, a Strengths, Weaknesses, Opportunities, and Obstacles (SWOO) session was held with the Planning Committee. The purpose of this session was to review information garnered from the risk assessment and the public involvement strategy to identify strengths, weaknesses, opportunities and obstacles in hazard mitigation within SC through a facilitated brainstorming session on risks, vulnerabilities, and capabilities. All information shared during this session was recorded and used to prepare catalogs of mitigation alternatives to be used by the Planning Committee in preparing their DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 6-0 DRAFT - September 2007 SECTION 6: MITIGATION STRATEGY individual jurisdictional annexes. Many of the strategies (such as community outreach) identified in the catalogs could be applied to multiple hazards. This Plan identifies strategies for multiple hazards for the County as a whole in this section (Section 6), and in each jurisdictional annex for participating jurisdictions (Section 9), even though a separate catalog for multiple hazards is not presented. The Planning Committee generated a comprehensive list of mitigation actions (see Appendix D) to be considered that met the following objectives: · Use information obtained from the public involvement strategy; · Use information provided in the risk assessment; · Seek mitigation actions consistent with the goals and objectives for the SC Plan; Create catalogs of mitigation actions to be used as a tool by the Planning Committee in selection of mitigation actions. Catalogs of Mitigation Actions Based on information gathered during the SWOO session, catalogs of mitigation actions were created that list initiatives that could manipulate the hazard, reduce exposure to the hazard, reduce vulnerability to the hazard, and increase the Planning Committee's ability to respond to or be prepared for a hazard (see Appendix D). These catalogs are separated by responsibility for implementation (in other words, who would most likely implement the initiative: personal property owners, private sector business, or government). The hazards addressed by the catalogs were deemed to be those to which the planning area is most vulnerable based on the risk assessment. The catalogs are not meant to be exhaustive or site-specific but rather to inspire thought and provide members of the Planning Cormnittee a baseline of initiatives backed by a planning process, consistent with the goals and objectives of the planning area, and within the capabilities of the Partners. The Planning Committee was not bound to these actions. They could have added to the catalogs if an action was not included. Actions in the catalogs that were not selected by the Partners in their jurisdictional annexes were not selected based on the following: · Action is currently outside the scope of capabilities (funding) · The jurisdiction is not vulnerable to the hazard · Action is already being implemented All proposed mitigation actions were identified in relation to the goals and objectives presented above. The mitigation actions include a range of options in line with the six types of mitigation actions described in FEMA guidance (FEMA 386-3), including: Prevention: Government, administrative or regulatory actions or processes that influence the way land and buildings are developed and built. These actions also include public activities to reduce hazard losses. Examples include planning and zoning, floodplain local laws, capital improvement programs, open space preservation, and storm water management regulations. o Property Protection: Actions that involve (1) modification of existing buildings or structures to protect them from a hazard or (2) removal of the structures from the hazard area. Examples include acquisition, elevation, relocation, structural retrofits, storm shutters, and shatter-resistant glass. DMA 2000 Hazard Mitigation Plan - Suffolk County, New Yolk DRAFT - September 2007 6-9 SECTION 6: MITIGATION STRATEGY Public Education and Awareness: Actions to inform and educate citizens, elected officials, and property owners about hazards and potential ways to mitigate them. Such actions include outreach projects, real estate disclosure, hazard infurmation centers, and school-age and adult education programs. Natural Resource Protection: Actions that minimize hazard loss and also preserve or restore the functions of natural systems. These actions include sediment and erosion control, stream corridor restoration, watershed management, forest and vegetation management, and wetland restoration and preservation. Emergency Services: Actions that protect people and property, during and immediately following, a disaster or hazard event. Services include warning systems, emergency response services, and the protection of essential facilities. Structural Projects: Actions that involve the construction of structures to reduce the impact of a hazard. Such structures include dams, setback levees, floodwalls, retaining walls, and safe rooms. County-Wide Mitigation Actions The mitigation actions are the key element of the natural hazards mitigation plan. It is through the implementation of these actions that SC can strive to become disaster-resistant through sustainable hazard mitigation. For the purposes of this Plan, mitlgation actions are defined as follows: Mitigation actions are activities designed to reduce or eliminate losses resulting from natural hazard~. A hhough one of the driving influences for preparing this Plan was grant funding eligibility, its purpose is more than just access to federal funding. It was important to the Planning Committee to look at mitigation actions that will work through all phases of emergency management. Some of the actions outlined in this Plan may not grant eligible~grant eligibility was not the focus of the selection. Rather, the focus was the actions' effectiveness in achieving the goals of the Plan and whether they are within the County or each jurisdiction's capabilities. A series of County-wide mitigation actions were identified. These actions are summarized in Table 6-6, along with the hazards mitigated, goals and obje.ctives met, lead agency, estimated cost (see Table 6-7), potential funding sources and the proposed timeline. Jurisdiction-specific actions are listed in Volume 2 Section 9 of this Plan. The parameters for the timeline are as follows: · Short Term: To be completed in I to 5 years · Long Term = To be completed in greater than 5 years · Ongning = Currently being funded and implemented under existing programs.

The SC Planning Committee, along with their contract consultant, developed a prioritization methodology for the Plan that meets the needs of the County and participating jurisdictions while at the same time lneeting the requirements of Section 201.6 of 44 CFR. The mitigation actions identified (Table 6-6) were prioritized according to the criteria defined below. · High Priority: A project that meets multiple plan goals and objectives, benefits exceed cost, has funding secured under existing programs or authorizations, or is grant-eligible, and can be completed in I to 5 years (short-term project) once project is funded. · Medium Priority: A project that meets at least one plan goal and objective, benefits exceed costs, funding has not been secured and would require a special funding authorization under existing. programs, grant eligibility is questionable, and can be completed in I to 5 years once project is funded. · Low Priority: A project that will mitigate the risk of a hazard, benefits exceed costs, funding has not been secured, and project is not grant-eligible and/or timeline for completion is considered long-term (5 to 10 years). It should be noted that these priority definitions are considered to be dynamic and can change from one category to another based on changes to a parameter such as availability of funding. For example, a project might be assigned a medium priority because of the uncertainty of a funding source. This priority could be changed to high once a funding source has been identified such as a grant. The prioritization schedule for this Plan will be reviewed and updated as needed annually through the plan maintenance strategy described in Section 6 of this plan. Benefit/Cost Review Section 201.6.c.3iii of 44CFR requires the prioritization of the action plan to emphasize the extent to which benefits are maximized according to a cost/benefit review of the proposed projects and their associated costs. The County was asked to weigh the estimated benefits ora project versus the estimated costs to establish a parameter to be used in the prioritization of a project, utilizing the same parameters used by each of the participating jurisdictions as outlined in Volume 2 of this Plan. This benefit/cost review was qualitative; that is, it did not include the level of detail required by FEMA for project grant eligibility under the Hazard Mitigation Grant Program (HMGP) and Pre-Disaster Mitigation (PDM) grant program. This qualitative approach was used because projects may not be implemented for up to 10 years, and the associated costs and benefits could change dramatically in that time. Each project was assessed by assigning subjective ratings (high, medium, and low) to its costs and benefits, described in Table 6-7: Table 6-7. Cost and Benefit Definitions Existing funding levels are not adequate to cover the costs of the proposed project, and High implementation would require an increase in revenue through an alternative source (e.g., bonds, grants, and fee increases). The project could be implemented with existing funding but w~uld require a re- Medium apportionment of the budget or a budget amendment, or the cost of the project would have to be spread over multiple years. DMA 2000 Hazard Mitigation Plan 2 Suffolk co~niyl ~ew York 6:i6 DRAFT - September 2007 SECTION 6: MITIGATION STRATEGY Low The project could be funded under the existing budget. The project is part of or can be part of an existing, ongoing program. High Project will have an immediate impact on the reduction of risk exposure to life and property. Medium Project will have a long-term impact on the reduction of risk exposure to life and property or will provide an immediate reduction in the risk exposure to property. Low Long-term benefits of the project are difficult to quantify in the short term. Using this approach, projects with positive benefit versus cost ratios (such as high over high, high over medium, medium over low, etc.) are considered cost-beneficial and are prioritized accordingly. For many of the County initiatives identified, SC ]nay seek financial assistance under FEMA's HMGP or PDM programs. Both of these programs require detailed benefit/cost analysis as part of the application process. These analyses will be performed when funding applications are prepared, using the FEMA model process. The Planning Committee is committed to implementing mitigation strategies with benefits that exceed costs. For projects not seeking financial assistance from grant programs that require this sort of analysis, the Planning Committee reserves the right to define "benefits" according to parameters that meet .its needs and the goals and objectives of this plan. Using this approach, projects with positive benefit versus cost ratios (such as high over high, high over medium, medium over low, etc.) are considered cost-beneficial and are prioritized accordingly. Table 6-8 presents the results of applying the prioritization methodology presented to the set of mitigation actions identified by SC, and includes the following prioritization parameters: · Number of objectives met by the initiative · Benefits of the project (high, medium, or low) Cost of the project (high, medium, or low) Do the benefits equal or exceed the costs? · Is the project grant-eligible? · Can the project be funded under existing programs and budgets? · Priority (high, medium, or low) DMA 2600 Razard Mitigation Plan 2 S0ff0ik County, New York 6-17 DRAFT - September 2007 SECTION 6: MITIGATION STRATEGY Table 6-8.

DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT ~ September 2007 6-18 SECTION 6: MITIGATION STRATEGY Table 6-8 outlines SC's mitigation action implelnentation strategy including: · Mitigation actions for individual and multiple hazards · Mitigation objectives supported by each action. Goals are not listed because all objectives meet multiple goals. · Implementation priority · Potential funding sources for the mitigation action (grant programs, current operating budgets or funding, or the agency or jurisdiction that will supply the funding; additional potential funding resources are identified) · Estimated budget for the mitigation action (financial requirements for new funding or indication that the action is addressed under current operating budgets) · Time estimated to implement and complete the mitigation action · Existing policies, programs, and resources to support implementation of the mitigation action (additional policies, programs, and resources identified) Specific mitigation actions were identified to prevent future losses; however, current funding is not identified for all of these actions at present. SC has limited resources to take on new responsibilities or projects. The implementation of these mitigation actions is dependent on the approval of the local elected governing body and the ability of the community to obtain funding from local or outside sources. Where such actions are high priorities, the community will work together with NYSEMO, FEMA and other Federal, State and County agencies to secure funds. ' in general, mitigation actions ranked as high priorities will be addressed first. However, medium or even low priority mitigation actions will be considered for concurrent implementation. Therefore, the ranking levels should be considered as a first-cut, preliminary ranking and will evolve based on input from SC departments and representatives, the public, NYS£MO, and FEMA as the Plan is implemented. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York DRAFT - September 2007 6-19 SECTION 7: PLAN MAINTENANCE PROCEDURES SECTION 7: PLAN MAINTENANCE PROCEDURES This section describes the system that SC and all participating jurisdictions have established to monitor, evaluate, and update the mitigation plan; implement the mitigation plan through existing programs; and solicit continued public involvement for plan maintenance~ MONITORING, EVALUATING AND UPDATING THE PLAN This section presents the procedures for monitoring, evaluating, and updating the plan. The Suffolk County Mitigation Planning Committee intends to remain intact as the organization responsible for monitoring, evaluating and updating this Plan. The Suffolk County Hazard Mitigation Planning Coordinator shall continue to act as the coordinator for the MPC. Each participating jurisdiction is expected to maintain a representative on the MPC who will fulfill the responsibilities identified in this Section. The current membership of the MPC shall be identified on the SC Hazard Mitigation Plan website (web address TBD). Monitoring To monitor the implementation of the mitigation plan, MPC members will collect and process the annual reports from the departments, agencies and organizations involved in implementing mitigation projects or activities identified in Section 6 of this plan or conduct phone calls and meetings with persons responsible for overseeing the mitigation projects. The MPC representatives shall be expected to document, as needed and appropriate: · Hazard events and losses occurring in their jurisdiction including their nature and extent and the effects that hazard mitigation actions have had on impacts and losses, · Progress on the implementation of mitigation actions, including efforts to obtain outside funding for mitigation actions, · Any obstacles or impediments to the implementation of actions, · Additional mitigation actions believed to be appropriate and feasible, Public and stakeholder input and comment on the Plan. The status of the HMP will be discussed at an annual meeting of the Mitigation Planning Committee, to be held in the month of September. In August at least two weeks before the annual mccting, the SC HMP Coordinator will advise MPC members of the meeting date, agenda and expectations of the members. An annual report summarizing the previously mentioned activities will be written and maintained. These annual reports will provide data for the 5-year update of this HMP and will assist in pinpointing implementation challenges. By monitoring the implementation of the plan on an annual basis, the MPC xxill be able to assess which projects are completed, which are no longer feasible, and what projects may require additional funding. Finally, the MPC will periodically inform the public about the progress and success of its efforts through the SC HMP website, and other media outlets as appropriate. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 7-1 Draft - September 2007 SECTION 7: PLAN MAINTENANCE PROCEDURES Evaluating The evaluation of the mitigation plan is an assessment of whether the planning process and actions have been effective, if the Plan goals are being reached, and whether changes are needed. The mitigation plan will be evaluated on an annual basis to determine the effectiveness of the programs, and to reflect changes that ]nay affect mitigation priorities or available funding. The SC HMP Coordinator will be responsible for calling and coordinating the annual plan review meeting, and assessing progress toward meeting plan objectives and goals. The evaluation will assess whether: · Goals and objectives address current and expected conditions. · The nature or magnitude of the risks has changed. · Current resources are appropriate for implementing the HMP and if different or additional resources are now available. · Actions were cost effective. · Sche.dules and budgets are feasible. · Implementation problems, such as technical, political, legal or coordination issues with other agencies are presents. · Outcomes have occurred as expected. · Changes in county/city/town/village resources impacted plan implementation (e.g., funding, personnel, and equipment) · New agencies/departments/staff should be included. Specifically, the MPC will review the mitigation goals, objectives, and acti¥ities using performance based indicators, including: · New agencies/departments · Project completion · Under/over spending · Achievement of the goals and objectives · Resource allocation · Timeframes · Budgets · Lead/support agency commitment · Resources · Feasibility Finally, the MPC will evaluate how other programs and policies have conflicted or augmented planned or implemented measures. Other programs and policies can include those that address: · Economic Development · Environmental Preservation · Historic Preservation · Redevelopment · Health and/or safety · Recreation · Land use/zoning · Public Education and Outreach · Transportation DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 7-2 Draft - September 2007 SECTION 7: PLAN MAINTENANCE PROCEDURES The plan will also be evaluated and revised following any major disasters, to determine if the recommended actions remain relevant and appropriate. The risk assessment will also be revisited to see if any changes are necessary based on the pattern of disaster damages or if data listed in the Section 5.4 (Hazard Profiles) of this plan has been collected to facilitate the risk assessment. This is an opportunity to increase the community's disaster resistance and build a better and stronger community. Following the annual plan evaluation process, each jurisdiction will provide input to the annual report describing (1) the plan evaluation process; (2) that status of current mitigation activities or projects, and (3) any plan changes. The long term vision for the HMP is to integrate the plan maintenance efforts into County and local Comprehensive Plans and the Emergency Management Plans. By doing so, the MPC anticipates that: 1) 2) 3) Hazard mitigation planning will be formally recognized as an integral part of overall emergency management efforts; The Hazard Mitigation Plan and Comprehensive and Emergency Management Plans will become mutually supportive documents that work in concert to meet the goals and needs of County residents; and Duplication of effort can be minimized. Updating The mitigation plan will be updated every 5 years and will reflect the results of the annual plan evaluations. To facilitate the update process, the SC HMP Coordinator, with support of the MPC, shall use the fourth annual HMP meeting (September of 2012 assuming this plan is approved in 2008) to develop and commence the implementation a detailed Plan update program. The SC HMP Coordinator shall invite representatives from SEMO to this meeting to provide guidance on plan update procedures. This program shall, at a minimum, establish who shall be responsible for managing and completing the Plan update effort, what needs to be included in the updated plan, and a detailed timeline with milestones to assure that the update is completed according to regulatory requirements. At this meeting, the MPC shall determine what resources will be needed to complete the update. The SC HMP Coordinator shall be responsible for assuring that needed resources are secured or Following each 5 year update of the mitigation plan, the updated plan will be distributed for public comment. After all comments are addressed, the HMP will be revised and distributed to all planning group members and the New York State Hazard Mitigation Officer. Further, it is recognized that additional jurisdictions within Suffolk County may elect to join this Plan. Any such new Plan participants shall be formally included and documented in the five-year formal Plan update. Procedures for the addition of new Plan participants shall be reviewed with SEMO and FEMA prior to their formal inclusion in this Plan. DMA 2000 Hazard Mitigation Plan - Suffolk County, New York 7-3 Draft - September 2007 SECTION 7: PLAN MAINTENANCE PROCEDURES Implementation of Mitigation Plan through Existing Programs The MPC intends to incorporate mitigation planning as an integral component of daily government operations. MPC members will work with other local government officials to integrate the newly adopted hazard mitigation goals and actions into the general operations of government and partner organizations. A capability assessment is provided in each jurisdictional annex (Volume 2) and as Appendix H. Amending and maintaining this capability assessment is identified as a mitigation action in Section 6 of this Plan. The Planning Committee will identify additional policies, programs, practices, and procedures that could be modified to accommodate hazard mitigation actions. Table 7-1 below includes existing processes and programs through which the mitigation plan could be implemented. Table 7-1.
