I I I i I I SOUTHOLD85-DT.1/INTRO.1 6/10/85 1.0 INTRODUCTION The Town of Southold is contemplating establishing a publicly owned airport to serve the aviation needs of Southold Town and surrounding communities on the east end of Long Island. To determine the potential and feasibility of the Airport to serve general aviation users in the Town, Southold applied for a Planning Grant to the Federal Aviation Administration (FAA) under the Airport Improvement Program (AIP) of the Airport and Airway Improvement Act of 1982. In September 1983, a contract was awarded to PRC Engineering, Inc. (PRC), in association with Environmental Science and Engineering, Inc. (ESE), for the preparation of a comprehensive Airport Site Selection/Master Plan Study for the Town of Southold. This consolidated report is a combination of the first two project reports that documented the research, analyses, and findings of the Phase I and Site Selection portions of the Study. It will be revised and superceded by subsequent reports which will be produced during later phases of the project. At the conclusion of the Study, a final report will be issued together with a set of airport plans, all of which will thoroughly document the entire work program. 1.1 PURPOSE AND SCOPE OF STUDY This Airport Site Selection/Master Plan Study will identify the most feasible site for locating the proposed Airport and will also provide guidelines for the development of the facility. This development program will satisfy aviation needs within the context Of community goals and environmental considerations. It will provide a forecast of aviation demand for short- (1988), intermediate- (1993), and long-range (2003) periods and planned development of airport facilities for this activity within the constraints identified during the study effort. 1-1 I I I I i I I I SOUTHOLD8 5-DT. i/INTRO. 2 6/10/85 The Town of Southold is in need of an Airport Site Selection/Master Plan Study at this time for the following reasons: o The Town of Southold proper does not have a publicly owned, unrestricted-use airport. Mattituck Airport and Rose Field are both under private ownership with restrictions placed upon their use (the Town owns and operates Elizabeth Field on Fisher's Island.) Without a publicly owned airport, the Town is lacking in adequate aviation facilities to serve potential corporate, air taxi, commuter, and general aviation users; thus, these operators are taking their business elsewhere. However, the Town would like to be in a position to attract a portion of these potential users. In order to do this, it is felt that an airport equipped with runway lighting and navigational aids is necessary. o To ensure proper placement of the Town-owned airport, a comprehensive evaluation of alternative sites must be undertaken to catalog economic, environmental, and operational consider- ations. o The environmental impacts of developing the new Airport must be evaluated in view of the current environmental requirements set forth by Federal, State, and local governmental agencies. o To apprise the local community, through conferences, public meetings, and publication of the Study report itself, of present and future needs of the new Airport and the effects development will have on the local area. The main objective of this Study is to determine the feasibility of developing a publicly owned airport on the North Fork of Long Island. The next step in the process is the preparation of an airport master plan to determine the extent, type, and schedule of development needed to accommodate future aviation demand in the Town of Southold. The recommended development should satisfy aviation demand and be compatible with the environment, community development, and other transportation ! ! 1-2 I I I I I I I I SOUTHOLD85-DT.I/INTRO.3 6/10/85 modes. Above all else, the plan must be technically sound and economically feasible. The following objectives shall also serve as a guide in the preparation of the Study: o To provide an effective graphic presentation of the ultimate development of the proposed Airport; o To establish a schedule of priorities and phasing for the various improvements proposed in the plan; o To present the pertinent back-up information and data which were essential to the development of the Site Selection/Master Plan; o To describe the various concepts and alternatives which were considered in the establishment of the proposed plan; o To provide a concise and descriptive report so that the impact and logic of its recommendations can be clearly understood by the community and by those authorities and public agencies which are charged with the approval, promotion, and funding of the improve- ments proposed in the Study; o To ensure that the Airport thoroughly complements and supports the development envisioned for Southold Town; o To assess future environmental impacts on land surrounding the proposed Airport and provide recommendations to discourage incompatible development; and o To insure the reliability and safety of airport operations. 1.2 CONTENTS OF THIS REPORT This consolidated report covers the work tasks conducted during the Phase I and Site Selection portions of the work program. The work program of Phase I can be summarized in the following major subject areas: inventory of existing conditions, forecasts of aviation demand, and assessment of needed airport facilities in terms of their ability to accommodate potential future traffic volumes. The site selection task entailed a thorough analysis of alternative airport sites in Town. 1-3 I I I I I I I I SOUTHOLD85-DT.1/INTRO.4 6/10/85 This report is organized into six sections which are set out in a logical order that follows the sequence of work tasks accomplished. The detailed documentation of research and analyses is contained in Sections 3 through 6. These are preceded by Section 2, which summarizes the findings contained in this report, and Section 1, this introductory section. Section 3 contains information about the existing airport facilities in the Town of Southold and the study area, and the results of potential user surveys. Section 4 presents the forecasts of potential aviation demand that should be accommodated at the Town's Airport. Section 5 documents the assessment of needed facilities (demand/capacity) and also presents the facility requirements needed to accommodate the projected traffic volumes. Finally, Section 6 discusses the alternative airport sites and sets forth a recommendation for the preferred site to develop the new airport. 1.3 UTILIZATION OF REPORT DATA The data contained in this report form the basis of the study data bank and also the basis for airport feasibility and plan formulation and evaluation. The inventory of existing facilities serves as a reference for the determination of the transportation system on the North Fork. The air trade demand forecasts provide the potential traffic volumes in terms of based aircraft and aircraft movements which should be accommodated by the proposed airport. This forecast of demand can then be translated into needed airport facilities. The facility requirements, therefore, provide the basis for sizing of the Airport and the formulation of the plan which is designed to accommodate the projected demand. The site selection portion translates these facility requirements into an actual site. ! ! 1-4 I ! I I I I I I SOUTHOLD85-DT.1/INTRO.5 6/10/85 1.4 RELATED REGIONAL/LOCAL PLANNING The New York State DepartmEnt of Transportation has recently embarked on a regional aviation system plan for the area that includes the Town of Southold. This study, which is known as the Downstate New York General Aviation System Pian (GASP), is intended to address the future of general aviation activity and facilities in the downstate area. In addition, the Town of Southold is currently in the process of updating its Master Plan for the Town. The objective of this update is to refine the comprehensive development plan for the Town. The Airport Site Selection/Master Plan Study for the Town of Southold has been closely coordinated with both of these planning studies. This coordination effort is important in that the results of this Study should be incor- porated into both the GASP Study and the Master Plan Update. Likewise, findings and conclusions of these studies need to be considered in evaluating the feasibility of a publicly owned airport on the North Fork. 1-5 I I I I I I I I I I ! I I I I I SOUTHOLD85-DT. 1/FC. 1 6/10/85 2.0 FINDINGS AND CONCLUSIONS This section summarizes the highlights of this consolidated report. The purpose of the summary is to afford the reader a quick overview of the significant analyses performed by the Consultant. 1. A survey of registered aircraft owners and pilots considered to be within a reasonable distance of Southold Town (residing in the Towns of Southold, Shelter Island, and Riverhead) found that over 80 percent of the aircraft owners responding to the survey would anticipate using an airport in the Town. 2. A survey of 44 local businesses and professionals presently operating in Southold Town was conducted. Over 50 percent of those surveyed support the proposed airport and anticipate utilizing it. 3. By the year 1990, the tourist industry of Long Island will exceed $10.0 billion. The east end of Long Island will account for 40 percent of this total ($4.0 billion). Thus, the condi- tions which must prevail in order for aviation to prosper do exist, and future aviation growth in the Town appears to be strong through the year 2003. 4. In the towns surrounding Southold, there are 13 general aviation airports housing 874 based aircraft. In the Town of Southold, there are three airports housing 28 aircraft. These aircraft represent approximately 3.2 percent of the total aircraft based in the vicinity. It is anticipated that the based aircraft fleet at the new Southold Airport would consist of single- engine and light twin-engine aircraft for the duration of the study period. 5. Based general aviation aircraft at the new Southold Airport will double by the end of the planning period, with 67 based aircraft in 2003 compared to a base year (1984) total of 33. 2-1 I I I I I I I I I I I I I I Ii I I SOUTHOLD85-DT.1/FC.2 6/10/85 6. General aviation movements will increase from 16,900 in 1988 to 20,200 in 1993 and 31,500 operations in 2003. Air taxi/commuter operations are projected to total 9,800 in 1988 and increase to 12,500 in 1993 and 20,200 in 2003. Passenger enplanements are expected to be 17,640 in 1988, increasing to 22,500 in 1993 and 36,360 by the end of the study period in 2003. 7. Potential instrument approaches at the new Airport are projected to stand at a level of 930 in 1988 and rise to 1,842 approaches by the end of the study period in the year 2003. 8. General aviation peak-hour activity at the new Southold Airport is projected to increase from its initial level of 7 movements to 13 movements at the close of the study period. 9. Potential commuter/air taxi activity is forecast to be 46 movements per day during the peak summer season in 1988 and rise to 95 movements per day during the summer months (May-October) by the close of the study period in 2003. On an annual basis, air taxi/commuter activity is initially projected at a level of 9,800 operations to increase to 20,200 operations in 2003. These operations are expected to be conducted solely by small twin-engine aircraft (i.e. Piper Navajo, Cessna 402, etc.). 10. It is recommended that the proposed Southold Airport be ulti- mately constructed according to FAA criteria for a General Utility-Stage I Airport. FAA Advisory Circular 150/5300-4B defines such a facility as one that serves" . all small airplanes. Precision approach operations are not usually anticipated." Initial plans call for construction standards typical of a Basic Utility-Stage II airport. 11. Assuming a single-runway configuration, the new airport will have an airfield capacity of approximately 183,000 operations per year. This capacity rating is more than adequate in that the 20-year forecast of activity projects only 51,700 opera- tions. 2-2 I I I I I I I I SOUTHOLD85-DT. 1/FC. 3 6/lO/85 12. It is recommended that the primary runway be built at an initial length of 3,000 feet and an ultimate length of 3,600 feet to accommodate light twin-engine aircraft. If it is feasible to construct a secondary or crosswind runway, it should be constructed with an overall length of 2,400 feet initially and lengthened to an ultimate size of 2,900 feet. 13. Based on a comprehensive wind analysis, the optimal allgnment for the primary runway is northeast-southwest (04-22), with a southeast-northwest (13-31) orientation as the best crosswind alignment. 14. The minimum land requirement for a single-runway airport in Southold is 100 acres, and with a crosswind runway an additional 62 acres are needed. 15. In terms of navigational aids, it is recommended that the new airport be equipped with a nonpreclsion instrument approach, medium intensity runway edge lights (MIRLs), visual approach slope indicator (VASI) systems and runway end identifier lights (REILs) on both ends of the primary runway. 16. Initial landside facilities that are needed include: a 1,029-square foot terminal building; 8,640-square foot auto parking lot; 44,550-square foot transient aircraft parking apron; 38,000 square feet of based aircraft tie-down space; 20 T-hangar spaces; 3,200-square foot conventional hangar for based aircraft storage; 10,000-gallon underground fuel tank; and 13,000 square feet of aircraft maintenance facilities (hangar and apron). Recommendations are also set forth for expansion of the above facilities to meet increasing demand. 17. Based on a preliminary screening of 12 potential airport sites, two sites were identified as representing the most feasible opportunities for developing the Airport; Site 2, which is located at the northwest corner of Oregon Road and Alvahs Lane, and Site 5, which is situated north of County Route 48 and 1,000 feet east of Bridge Lane, emerged as the two most favor- able potential sites. m m 2-3 I ! I I I I I I I SOmOLDS~-DT. 1/FC. 4 6/10/8~ 18. A comprehensive alternatives evaluation of these two sites was conducted. The recommendation that resulted from this analysis was that the Town should pursue developing Site 5 as its municipal airport to serve Southold Town proper. 2-4 I I I I I I I I I SO~HOLD85-DT. 1/3 · 1 6/10/85 3.0 INVENTORY OF EXISTING CONDITIONS 3.1 TOWN OF SOUTHOLD The Town of Southold is a peninsula located on the North Fork of Long Island as shown in Figure 3-1. Southold Town proper is depicted in Figure 3-2, which shows the primary study area. Southold's western boundaries begin at Laurel and Mattituck just east of the Town of Riverhead and extend to Orient Point. Plum Island and Fishers Island extend northeastward from Orient Point. Robins Island is located south of Southold in the Peconic Bay. Ail of these islands are part of the Town of Southold. There are eleven communities within the Town of Southold. They are listed below along with their population, according to the 1980 census. o Cutchogue and New Suffolk - 2,788 East Marion - 656 Fishers Island - 318 Greenport - 2,273 Greenport West - 1,571 Laurel - 962 Mattituck - 3,923 Orient - 855 Robins Island - 0 Peconic - 1,056 Southold - 4,770 Total Town Population 19,172 3.2 ALTERNATIVES TO AIR TRANSPORTATION A basic set of alternatives that could affect the development of a publicly owned airport on the North Fork is the use of other modes of transportation in place of air travel. There are three primary modes that presently provide the type of long distance travel required: rail transportation, surface transportation, and shore-to-shore transporta- tion. ! ! 3-1 Figure 3-1 LOCATION MAP SOURCE: ESE, IJSW LoNG ISLAND soUND NASSAU couNTY suFFOLK couNTY oO~A~ SOUTHOLD, NEW YORK Airport Site Selection/ Master Plan Study Figure 3-2 PRIMARY STUDY AREA SOUTHOLD, NEW YORK A~IRPORT SITE SELECTION/ MASTER PLAN STUDY SOURCE: ESE, 1985 I I I I I I I I SOUTHOLD85-DT. 1/3.2 6/i0/85 3.2.1 Rail Transportation There is only one railroad line that serves the North Fork. This llne is part of the Long Island Railroad, which serves the entire Island. This east-west diesel tine ends at Greenport with intermediate stops at Southold, Cutchogue, and Mattituck. The railroad runs into Jamaica Station where passengers then transfer to electric trains into Manhattan. This trip usually takes approximately three hours. 3.2.2 Surface Highway Transportation There is one interstate highway that directly connects the eastern end of Long Island with Manhattan. This limited-access highway is the Long Island Expressway (LIE) or Interstate 495. The LIE runs west-east and ends in Riverhead. Once in Riverhead one must then take County Route 58 which turns into Route 25. This is the main route through Southold and is known as Main Road. County Route 48 (formerly designated County Route 27), known as the North Road, is the fastest route to all towns on the North Fork in that it is a four-lane improved highway. These two roads are the principal east-west arteries on the North Fork. A trip from Manhattan to the North Fork by automobile usually takes 2-1/2 to 3 hours if traffic is light and weather conditions are good. No major bus companies have requested permits to provide scheduled bus service directly from New York City to the other communities on Long Island; therefore, the major bus companies do not operate to the east end of the Island. There are several local bus companies that do offer service to the North Fork and other Long Island communities. There is local bus service to Riverhead and East Hampton from Greenport (Route S- 92) and smaller bus feeder service from Orient Point to Mattituck (Route 9A) and Riverhead (Route SA). Busses on Routes 8A and 9A do not have connecting schedules or routes. 3-4 I I I I I I i I SOUTHOLD85-DT.I/3.3 6/10/85 3.2.3 Shore-to-Shore Transportation There is daily ferry service to/from Shelter Island and Greenport and to/from Orient Point and New London, Connecticut. There ia ferry service from New London to Fishers Island but no direct service is available between the North Fork and Fishers Island, both of which are part of the Town of Southold. There is also no public ferry service to Plum Island, which is owned by the federal government and off limits to the general public. The only service available is strictly enforced by the U.S. Government and is used by government employees commuting to Plum Island. 3.3 HISTORY OF AVIATION IN THE TOWN OF SOUTHOLD The first airport opened in the Town of Southold was Mattituck Airport, which commenced operations in 1946. In its early days, Mattituck Airport was a privately owned facility with a single grass strip that supported the commercial operations of Mattituck Aviation. This airport was opened to the public on a limited basis. In 1948, Rose Field in Orient was opened. It consisted of a short grass runway and was utilized by Cross-Sound Air Taxi Service. Rose Field was a restricted field and thus not opened to the public. Aviation facilities in the Town of Southold remained status quo until 1959 when the Town assumed the ownership of Elizabeth Field on Fisher's Island. The federal government, which built Elizabeth Field, turned it over to the Town of Southold in 1959, giving the Town its first publicly owned airport. In 1960, Malcolm S. Spelman Associates prepared the "Comprehensive Plan and Development Program for Airports and Air Terminals in Suffolk County." This study recommended that the Town of Southold maintain its 3-5 I I I I I I I I SO~HOLI)85-DT. 1 / 3.4 6/10/85 three aviation facilities (Mattituck, Rose, and Elizabeth) and implement some modest improvements. Funds were made available for improving the Town's airports, but were not accepted by the Town. Mattituck Airport was utilized for transporting freshly harvested scallops in 1963. However, this operation was hampered during wet periods due to the turf composition of the runway. In response to this situation, the Town of Southold conducted a public hearing on establish- ing an all weather airport in the Town. The Southold Town Board voted unanimously to develop such a facility. As a result, Msttituck Airport was leased by the Town for a period of ten years, beginning in 1964. The Town Highway Department constructed a hard surface runway. The lease also included provisions for the installation of runway edge lighting. In 1967, the Town of Southold retained the services of Raymond and May Planning Consultants, to update the "701" Master Plan for the Town. At that time, only three years of the 10-year lease with Mattltuck Airport. had elapsed. The plan included a general aviation airport north of Oregon Road in Mattituck. A requirement of "701" approval was that if an airport had ever been proposed for the area, it must be included in the plan. This particular site had been proposed by Suffolk County, the New York State Department of Transportation, Bureau of Aviation and others. After some revisions to the plan, informational hearings were held in August and September of 1969. These hearings, while generally favorable, identified two specific areas of disagreement. The first point of disagreement was the airport and the other was the future of agriculture in the Town of Southold. As a result of these areas of disagreement, the airport was deleted from the plan and a comprehensive study of the future of agriculture was undertaken. On October 2, 1970, the final informational hearing was held on the Master Plan for the Town. At this meeting, 85 percent of those in attendance expressed approval of the plan as presented. As a result of this approval, the Southold Town Board, on 3-6 I ! I I I I I I SOU~OLD~5-DT.1/3.5 6/10/85 November 23, 1971, amended the zoning ordinance in its entirety, including adoption of a revised zoning map. Finally, on September 11, 1973, the Town Board authorized the code book which resulted in revision, re-numbering and codification of the plan. It also made permanent all Town ordinances, local laws, and rules and regulations. The initial lease for Mattituck Airport expired in 1974, at which time the Town renewed it for another five years. However, the provision for runway lighting was deleted from the new lease. The Development Plan of the Tow~ of Southold was prepared and submitted to the Town Board for approval in September, 1978. However, no action was taken on this plan. The zoning map which accompanied this plan, did not show any aviation facilities in the Town, existing or proposed. At the Town Board meeting of June 6, 1978, Supervisor Martocchia made the following statement: "There has been some discussion relative to the Mattituck Airport not providing enough service. There is less than a year to go on the Mattituck Airport lease, and although a renewal is pretty well assured...," he appointed Councilman Henry Drum to head a committee to make a study among the Southold Town residents, to determine the cost to lease or purchase land. Councilman Drum was asked to organize his own committee members. Councilman Drum was appointed because of his 30 years in the U.S. Navy, many of which were in an administrative position; he retired as a Captain. Supervisor Martocchia felt he would be the most qualified to gather these statistics. The study was to address the loss of income from taxes, the cost to the Town, the cost of building, staffing, and equipping an airport to make operational, and if the purchase of land was warranted. 3-7 I ! I I I I ! I } SOUTHOLD85-DT. 1/3.6 6/10/85 It was noted by Supervisor Martocchia that: "There are many items which may come into the picture, such as state or federal aid." He then announced that: "This report will be sobmitted three months prior to the expiration of the Mattituck Airport lease in March of 1979." In 1979, Councilman Drum appointed the following to the committee to study the airport issue: Henry Raynor, Deputy Chairman of the Town Planning Board; Frank Bear, President of the North Fork Environmental Council; and David Spohn, airline captain and interested Town resident. The lease between the Town of Southold and Mattituck Airport, which expired in 1979, was not renewed. This left the Town of Southold proper without an unrestricted public use airport. In response to this situa- tion, the Town Board in 1980, applied for federal funds under the Airport Development Aid Program (ADAP) to undertake a study to determine the feasiblity of establishing a Town-owned airport. Unfortunately, the legislation authorizing the distribution of the necessary funds expired. shortly after the Town's application was filed. The lapse in legislation lasted for two years until Congress passed the Airport and Airways Improvement Act of 1982, which included the Airport Improvement Program (ALP) as its funding mechanism. Once again federal funds were available for airport planning and development. As previously stated, FAA made a grant offer to the Town in September 1983, which the Town Board promptly accepted to allow initiation of the airport feasibility study. The Town Board recently authorized an update of the Town Master Plan. The draft version of this update, which was prepared by Raymond, Parish, Pine and Weiner, Inc. (RPPW) was submitted to the Town for review on April 29, 1985. It is interesting to note that the proposed zoning for airport facilities in the draft of the Master Plan Update is" .left in the Industrial District requiring a 100-acre minimum site and is limited to a Basic Utility-Stage II airport." None of the three airports I I 3-8 I ! I I ! i I SOUTHOLD85-DT.1/3.7 6/10/85 that presently exist in the Town of Southold are zoned industrial; they are all zoned for residential use (Mattituck Airport and Rose Field are zoned R-80, Residential Low Density A, and Elizabeth Field on Fishers Island is zoned R~120, Residential Low Density B). See Appendix I for a description of the proposed zoning categories. Further, there is not one parcel of land in the Town that has a minimum size of 100 acres and is zoned for industrial use. One recent development that may affect the status of aviation in Southold Town is that Mattituck Aviation has recently sold its aircraft engine overhaul and distribution business to a firm located in Ohio. This situation should be watched closely in that it could affect the future of Mattituck Airport. 3.4 INVENTORY OF EXISTING FACILITIES The purpose of performing a comprehensive inventory of existing airport facilities in the area is that in later phases of the work program, these facilities will be assessed as to their ability to accommodate future traffic volumes. This is important in that other airports in the area will affect the potential demand at the proposed airport in Southold. The following section describes airport conditions and facilities existing on Long Island in a 40-mile radius from the center of the Town of Southold (Town Hall). The purpose of this study area is to determine the impact of neighboring airports on the new Southold Airport. The impact of surrounding airports must be considered in determining the particular role of, and potential demands for the Airport. For this purpose a total of 19 airports were considered and analyzed to obtain an up-to-date reading on their operations and facilities. These airports are depicted in Figure 3-3 and discussed in Table 3-1. From the 19 airports analyzed, a total of 9 airports have paved runways and 12 are 3-9 Y N NEW LONDON CALVERTON MOA CA L VER TON I MOA Figure 3-3 TOWN OF SOUTHOLD AIRPORT SITE SELECTION STUDY AIRSPACE ENVIRONMENT AND ADJACENT AIRPORTS SOURCE: ESE, 1~8S SOUTHOLD, NEW YORK Airport Site Selection/ Master Plan Study Table 3-1.

The source of specific airport information, including aircraft operations, is FAA Form 5010-1 and Airports 1984, which is published annually by the Aircraft Owners and Pilots Association (AOPA). 3.4.1 Airspace Environment As can be readily observed in Figure 3-3, the area is traversed by a network of low altitude "Victor" airways. Most of these airways inter- sect at one of the three VOR facilities in the area. A VOR facility is a ground-based, very high frequency, omnidirectional radio station that transmits radials in all directions. It provides azimuth guidance to pilots. The area's VOR stations are: o Calverton (CCC) VORTAC - 117.2 MHz o Hampton (HTO) VORTAC - 113.6 MHz o Madison (MAD) VORTAC - 110.4 MHz Also shown in Figure 3-3 is the Terminal Radar Service Areas (TRSA) for - Long Island MacArthur Airport. This area identifies the airspace surrounding MacArthur wherein Air Traffic Control provides radar vector- ing, sequencing, and separation on a full-time basis for all IFR and participating VFR aircraft. Although pilot participation is urged, it is not mandatory within the TRSA. A restricted area (R-5202) is also shown off the end of the North Fork. This area is designated as Calverton 2 MOA (Military Operating Area), which is restricted between the hours of 0600 and 2300. Adjacent to R-5202 is 'Calverton 1 MOA, which serves as a warning to pilots that aircraft may be performing unusual flight activities in this area. Airport Control Zones are also shown in Figure 3-3. These are areas of controlled airspace and exist from the ground up to the base of the Continental Control Area (14,500 feet msl). As seen, a number of airports have published instrument approach procedures in effect. There are presently no airports in the immediate vicinity of the North Fork that have published instrument approach procedures. The closest airports that do have such procedures are 3-14 I I ! I I I I I SO~HOL~5-DT.I/3.9 6/10/85 Calverton, Suffolk County, and East Hampton Airports. Calverton has a straight-in approach to Runway 32 and a circling approach, both utilizing the Calverton (CCC) VORDME facility. Neither of these instrument approach procedures require overflying the Town of Southold. East Hampton Airport has a published circling approach using the Hampton (HTO) VOR facility. East Hampton also has an RNAV approach to Runway 10. This procedure relies on the HTO VOR facility and area navigation equipment located five nautical miles west of the runway threshold. Neither of these instrument approach procedures necessitate flying over the Town of Southold. Suffolk County Airport has three published instrument approach procedures. The first procedure is the instrument landing system (ILS) approach to Runway 24, which has three principal components: localizer, glide slope, and outer marker. The outer marker is a non-directional radio beacon (NDB) that serves as the Initial Approach Fix (IAF), which is situated 4.6 nautical miles from the threshold of Runway 24 on a heading of 235 degrees. The glide slope is an on-airport electronie component that emits signals to provide the pilot with vertical guidanc~ to assist in the approach and landing phase. The localizer component is also an on-airport facility physically placed on the other end of the runway that it serves. It is an electronic component that provides course guidance to the runway. The three published instrument approach procedures utilize at least one of the components of the ILS. Naturally, the ILS procedure on Runway 24 uses all of the components. A localizer (LOC) back eourse to Runway 06 utilizes the same localizer facility but to the opposite end of the runway. The third procedure utilizes the NDB for an approach to Runway 24. None of these instrument procedures require flying over the Town; however, if an instrument procedure were established to Southold's Airport from the south or southwest, a potential conflict during IFR conditions with aircraft landiag on Suffolk County Airport's Runway 24 is possible. No other airspace conflicts are anticipated if the Town proceeds with establishing an airport. I I 3-15 I I I I I I I I SOUTHOLD85-DT.I/3.10 6/lO/85 3.4.2 Airports in the Town of Southold A. Eastern Long Island Hospital Eastern Long Island Hospital maintains its own heliport for medical emergencies. It is restricted to private use, and thus this heliport located on the hospital grounds in Greenport is not capable of accommo- dating any of the potential traffic in Southold Town. B. Elizabeth Field Elizabeth Field is located on Fishers Island. The Airport is owned by the Town of Southold and is opened to the public. The draft Town Master Plan recommends that Elizabeth Field be zoned R-120 (Residential Low Density B). It is located northeast of Southold and approximately eight miles southeast of New London, Connecticut. Its two runways 07/25 and 12/30 are paved with asphalt. The Airport is usable during instrument weather conditions (IFR) in that it has a VOR approach. VOR refers to a very high frequency, omnidirectional radio station for navigational and landing purposes. Tie-downs are available and the Airport is attended during daylight hours. Elizabeth Field is also equipped with runway edge lighting. Fishers Island is accessible to the Town of Southold proper by ferry service to New London, Connecticut, and then to Fishers Island. Fishers Island is also accessible by air from the two other private airports in Southold or by private boat across the Long Island Sound. The annual operations (opns) at Elizabeth Field, which has two based aircraft, are estimated as follows: Air Taxi 5,000 GA Local 1,200 GA Itinerant 3,800 Military 100 Total Opns. 10,100 3-16 I I I I I I I I SOUTHOLD85-DT. 1 / 3.11 6/10/85 C.

Potential demand for a new general aviation airport in the Town of Southold does exist. A survey of registered aircraft owners and pilots considered tn be within a reasonable distance of the Town of Southold fonnd that over 80 percent of the pilots responding to the survey would anticipate using an airport in the Town. The survey form was sent to individuals residing in the Towns of Southold, Shelter Island, and Riverhead. This subsection will discuss the above mentioned survey questionnaire. The Consultant (PRC/ESE) sent out 62 separate survey forms to registered aircraft owners and pilots in the above mentioned towns in November of 1983. A copy of the questionnaire appears as Appendix B. Each question is summarized as to the percentage of pilots responding to the questionnaire. Seventy-nine percent of the pilots (49 responses) involved have responded, and the results are as follows (the number in parenthesis is the actual number of respondents): o Questions #1 and #2 asked for the name and address of the respondent. ! I 3-22 I I I I I I I I SOUTHOLD85-DT.1/3.17 6/10/85 o The results of Question #3, which asked for the number of flight hours flown annually, are as follows: 0-99 Hours - 55% (27) 100-300 Hours - 25% (12) 301-500 Hours - 2% (1) Over 600 Hours - 18% (9) o Question #4 asked for the surveyed. The results are as follows: Student - 12% (6) licenses and ratings of the pilots Private - 43% (21) Commercial - 31% (15) . Instrument - 39% (19) ATR - 29% (14) Multi-Engine - 31% (15) Flight Instructor - 33% (16) Rotorcraft - 2% (1) Note that some individuals hold more than one license and/or rating, which results in the above percentages totaling in excess of 100 percent. o Question #5 asked if the pilot owned his own aircraft, and if so, where it was based. The results of this question are discussed below. Of the 49 responses received, 51 percent (25 pilots) do not own their own aircraft. The remaining 24 pilots do own their own aircraft, and it should be noted that some of them own more than one aircraft. In fact, these 24 individuals who stated that they are aircraft owners own a total of 36 aircraft. Of these 36 aircraft, 94 percent (34) are single-engine aircraft; the 3-23 I I I I I I I I SOUTHOLD85-DT.1/3.15 6/10/85 remaining two aircraft are multi-engine types. These aircraft are based at seven separate airports on Long Island and two airports in Connecticut as follows: - Mattituck Airport - 9 aircraft - Shelter Island - 5 aircraft - Suffolk County Airport - 4 aircraft - Talmage Field - 3 aircraft - Rose Field - 3 aircraft - Riverhead Airpark - 2 aircraft - East Hampton Airport - 1 aircraft - Airports in Connecticut - 9 aircraft Of the above 36 aircraft owners, 25 (69 percent) have indicated that they would relocate their base of operations to the proposed airport in Southold Town. Another 5 (14 percent) stated that they would utilize the facilities at the~new airport. The remaining 6 aircraft owners (17 percent) do not anticipate utilizing the Town's airport. Question #6 was directed towards pilots who are not aircraft owners. The question asked what airport these pilots used most often. The results are as shown below: Suffolk County Airport - 36% (9) Mattituck Airport - 32% (8) Long Island MacArthur Airport - 8% (2) Rose Field - 8% (2) Out of State - 4% (1) Republic Airport - 4% (1) Brookhaven Airport - 4% (i) John F. Kennedy International Airport - 4% (1) I I 3-24 I I I I I I I I SOUTHOLD85-DT. 1 / 3.19 6/10/85 o The next question, #7, asked all of the respondents to rate the airport and its facilities that they utilize most often. A summary of the base airports, their facilities and how they are rated by the pilots using them is shown in Table 3-2. o Question #8 asked the pilots what type of aircraft they use most often. The following shows the results of this question. Single-Engine 1-3 Place - 43% (21) Single-Engine 4+ Place - 53% (26) Multi-Engine <12,500 Lbs - 8% (4) Turboprop >12,500 lbs - 2% (1) Note that the percentage total does not equal 100 percent, and that the actual number does not total 49; this is because some respondents gave multiple aircraft types. o There are four main reasons pilots reported for using a particular base airport, as discovered from Question #9. The results are as follows: Close to Home - 41% (20) Convenience - 16% (8) Facilities (Flight School, Night Operations, Approach Facilities, etc.) - 29% (14) No Airport in Soothold Town - 14% (7) o Question #10 asked for the primary source of flight activity from the pilots responding. The results of this question are as follows: Personal - 65% Business - 37% Student - 18% Instructor - 20% Air Taxf (Pass.)- 6% 3-25 8CUIllI~U)-T. 1/H~3-2.1 Table 3-2.

O There are two types of operations - itinerant and local. Itiner- ant operations are those flights for which the flight either begins or ends at an airport other than the base airport. All other operations are considered local (i.e., touch-and-go's are local operations). Question ~11 asked for an estimate of local versus itinerant activity. The results of this question from the responding pilots relative to their activity during the past 12 months are shown below. Operations Local Itinerant N/A 22% (11) 37% (18) 1-50 37% (18) 45% (22) 51-99 16% (8) 8% (4) 100-199 12% (6) 0% (0) 200-300 2% (1) 2% (1) Over 300 8% (4) 8% (4) Question #12 asked directly if the pilot would relocate his flying activity to Southold if the Town established a new airport. Eighty-four percent (41) of the pilots responding would relocate and use the new airport. Ten percent (5) would not relocate but would use the facilities.

In March 1984, 44 separate survey forms, a copy of which is included as Appendix C, were mailed to various business and professional concerns, soliciting their interest in the airport and how it might affect their normal business activities. Of the 44 surveys sent out, 25 responses were received, which represents'a response rate of 57 percent. It is interesting to note that all of the responses received favored a Town- owned airport. Thus, it is assumed that the remaining 1~ forms that were not returned were sent to concerns who would not utilize the airport in Southold Town. The intent of this section is to present the results of the business survey. o The first question asked if the business or professional would use the new airport. All 25 respondents answered in the affirmative. The next part of this question asked for the most frequent destinations and what type of aircraft would be used (i.e., charter, private, air taxi, etc.). The most frequent destination mentioned were points in New England including destinations in Connecticut, Rhode Island, and Massachusetts. Private (52 percent) was listed most often as the type of aircraft. Charter and taxi aircraft were both mentioned by 32 percent and 16 percent were unsure. The above percentages do not total 100 percent in that some respondents listed more than one type. The second question asked if the particular business owned privte aircraft. Fifty-two percent (13 respondents) do own at least one aircraft, forty-four percent (11 respondents) do not have aircraft, and one respondent stated that he would consider purchasing an aircraft if the Town proceeded with establishing an airport. Among the 13 respondents who do own aircraft, there are 27 aircraft, 18 of them are single-engine and 9 are multi-engine aircraft. 3-31 I ! I i I ! I I I SOUTHOLD85-DT.1/3.22 6/10/85 The third question queried how often the proposed Southold Airport would be used on a monthly basis. Of the 25 respondents, 16 of them (64 percent) stated that their use of the facility would amount to less than ten times per month. Five (20 percent) others estimated that their monthly frequency of use would range between 11 and 20 times. The remaining four respondents (16 percent) expect that they will utilize the new airport in excess of 20 times per month. The next question inquired whether or not use of the airport would vary according to season. Fourteen of the responses (56 percent) indicated that their use 'of the facility would vary depending upon the season, while the remaining 11 respondents (44 percent) expect that their activity would remain reasonably well-balanced throughout the year. O The fifth question asked whether an airport established in Southold Town would enhance their business. Remarkably, 84 percent of the respondents (21) stated that a publicly owned airport on the North Fork would enhance their business. Only four respondents (16 percent) said that it would not affect their business; however, one of them did state that it would be a convenience to his operation. The final question asked if it would be advantageous to be able to make one-day business trips, which is possible with a Town airport, versus longer trips due to deficiencies in transportation to/from the North Fork. Surprisingly, 88 percent of those respond- ing (22) said that it would, while the other three did not feel that 1-day trips were an advantage. 3-32 I I i ! I I i I SOUTHOLD85-DT.1/3.23 6/lO/85 3.5.3 Conclusions The principal reason for conducting these two surveys was to identify the potential aviation activity and in turn determine the need for a publicly owned airport on the North Fork. It seems that the need for the airport is present and that there should be no difficulty in attracting users. In addition, the majority of the business community members in the Town are supportive and have stated their need for the facility. In short, the proposed Southold Airport certainly seems to be a most feasible endeavor and should be pursued. 3.6 METEOROLOGICAL CONSIDERATIONS Meteorological considerations for the proposed Southold Airport focused on a comprehensive review of weather observations taken at Suffolk County Airport and Tweed-New Haven Airport. This was necessary since no U.S. Weather Bureau (USWB) reporting station currently exists on the North Fork. The meteorological analysis consisted of review of 43,818 weather observations taken at Suffolk County Airport over the 10-year period between 1954 and 1963 and 36,480 weather observations taken at Tweed-New Haven Airport over the 10-year period from 1955 to 1964. The results of these weather observations were compiled and checked for consistency in terms of wind orientation to assist in identifying the optimal runway alignment that should be pursued at the proposed Southold Airport. One additional weather station was utilized to confirm the results of the composite Suffolk County/New Haven analysis. This weather station, which is not approved by the USWB, has taken observations of wind direction and speed on the North Fork. It is operated by the Long Island Lighting Company (LILCO) and is located in Jamesport. The weather analysis culminated in the preparation of the wind roses depicted in Figure 3-4, which are a compilation of the weather observations taken at Suffolk County and Tweed-New Haven Airports. Table 3-4 shows the wind orienta- tion broken down by velocity (greater than 5 knots and greater than 10 knots). The reason for this breakdown is that most small general aviation aircraf~ can operate safely with a 5-knot crosswind; however, 3-33 ALL WEATHER WIND ROSE PERCENT OF VRF WEATHER - 83.47% PERCENT OF IFR WEATHER - 16.53% PERIOD: 1954-1963 (43,818 OBSERVATIONS AT SUFFOLK COUNTY AIRPORT) 1955-1964 (36,480 OBSERVATIONS AT TWEED-NEW HAVEN AIRPORT) LOW VISIBILITY WIND ROSE (LESS THAN 1000' CEILING, LESS THAN 3 MILES VISIBILITY) Figure 3-4 WIND ROSES--PROPOSED SOUTHOLD AIRPORT SOURCE: NATIONAL OCEANIC & ATMOSPHERIC ADMINISTRATION.

Thus, it is important to consider the wind orientation when wind speeds exceed 10 knots to determine the most effective runway alignment. By reviewing Figure 3-4, it is clear that the predominant wind direction is from the southwest, during both VFR and IFR weather conditions. The wind patterns that have resulted from this analysis show that the North Fork is typical of most of Long Island, with the wind orientation distributed among all directions. During VFR conditions, the next three most frequent directions of wind occurrence are northwest, west- northwest, and north-northwest. The next three most frequent IFR wind orientations are northeast, north-northeast, and east. It should be further noted that the fact that southwest is the predominant wind direction also coincides with LILCO's readings at its Jamesport reporting station. 3-36 I I I I I I SOUTHOLD85-DT.1/4.1 5/29/85 4.0 FORECAST OF AVIATION DEMAND 4.1 INTRODUCTION Historically, transportation has been the controlling factor in the original location of man's political and economic environment. This is clearly true in the Town of Southold, where the early settlers had little choice but to locate at points available to water transportation, either on the Long Island Sound or at Greenport on the Peconic Bay. Therefore, townspeople looked to New London, New Haven, New York City, and Boston as markets for their prodocts, the primary source for their supplies, and the bankers for their enterprises. The impact of seacoast-oriented water transportation on the economy of Southold was reinforced by early roads and by railroads, since both generally followed the then-established patterns of trade. Thus for some 300 years after the founding of Greenport, Mattituck, and New Suffolk, Southold's economy continued to be tied directly to the developments of water transportation, which linked it directly to the New England region. The era of modern highway transportation gave Southold its first opportunity to free itself from its necessary dependence on New England as a hub of economic activity. While the highway system as it has developed to date is far from ideal, Southold no longer needs to look to New England to develop its economic relationships. The Town can now look west, to New York City, with greater ease than traveling to New England. Air service, to which the Long Island Sound would not impose a barrier and which would provide Southold with flexibility in its ioterregional transportation system, has been achieved only to a limited degree at best. However, the opportunity does exist for improved air service provided the right conditions exist. 4-1 I I I I I I i i I. SOUTHOLD85-DT.1/4.2 5/29/85 This section will evaluate the conditions which must prevail for aviation to exist and prosper. Since the Town of Southold is part of Suffolk County and since economic data at the township level does not exist in the State of New York, the socioeconomic analysis of the environment of Southold will first analyze the overall Long Island Region, especially Suffolk, and then consider the economy of Southold in relation to that of the region, with particular interest in evaluating the growth potential of the Town of Southold. 4.2 POPULATION OF LONG ISLAND The population of the Long Island Region during the 1960.to 1970 period grew at an annual rate of 2.7 percent. It rose from a level of 1,967,000 persons in 1960 to 2,555,800 persons in 1970, as recorded by the U.S. Bureau of the Census. However, between 1970 and 1980, the population growth rate decreased considerably. Population grew at an average annual rate of only 0.2 percent. This limited growth is attributable, in part, to specific policies of various governmental agencies to slow down or retard growth in the region. It is anticipated that by the year 2003, the total population of the Long Island Region will reach 2,905,000 persons, which reflects an average annual growth rate of 0.5 percent over 1980. This is a slight increase in the region's population growth rate over the 1970 to 1980 period (see Table 4-1). 4.2.1 Center of Lon~ Island Population The approximate center of population for the region, as calculated in 1980 (Table 4-2), was 40°45'11'' latitude and 72°80'55'' longitude. This location is slightly west of the Nassau/Suffolk border line (Figure 4-1). The location of the center of population, given the potential population growth rate to the year 2003, suggests that the Town of Southold will be about 50 miles from the center of population. Thus the Town of Southold lies on the ring of the population base. 4-2 i J J ! i Table 4-1.

I I I I I I SOUTHOLD85-DT.1/4.3 5/28/85 The center of population for Suffolk County lies in the Town of Brookhaven, still a considerable distance from the Town of Southold (Figure 4-2). Suffolk County's center of population in 1980 has been calculated to lie at a point 40°46'94'' latitude and 72°69'39'' longitude. 4.2.2 Population of Southold The permanent population of the Town of Southold rose from 16,804 persons in 1970 to 19,172 persons in 1980. However, since the purpose of this study is to assess the potential for aviation activity in the Town of Southold, it is necessary to assess both the permanent residents and the summer residents in the Town. ~ According to the 1980 Special Census of the Population, the net increase in the summer residents was 20,646 persons. Table 4-3 shows these estimates, which were prepared by the Long Island Regional Planning Commission. Combining these figures (summer residents) plus the permanent residents shown in 1970, the total population market was approximately 30,000 persons. By 1980, the population market rose to 29,818 persons, representing an average annual growth rate of 3.6 percent between 1970 and 1980. This was almost three times the growth rate of Suffolk County during the same period. The observation to be made is that Southold's population market is growing faster than the population market for Suffolk County. Through the period from 1980 to the year 2003, the Southold population market is expected to grow by 1.4 percent annually through 1993 and by 1.1 percent annually thereafter. Thus, the Southold population market by the year 2003 is estimated to be 53,100 persons, a population which would exceed the growth rate for both the County of Suffolk and the Long Island Region.

I I I I I I SOUTHOLD85-DT.1/4.4 5/28/85 4.3 INCOME The median family income of the permanent residents in the Town of Southold in 1979, as well as in 1970, was lower than for Suffolk County as a whole. Both Southold and Suffolk County are considerably less affluent than Nassau County. The median family income in Nassau in 1979 was $26,246 compared to $24,195 for Suffolk and $21,013 for Southold. In the 10 years under study, Suffolk County was gaining relative to Nassau County, primarily because of the influx of new residents. The increase was +2.56 percent in Suffolk compared to +2.33 percent in Nassau. However, the Town of Southold, compared to either Nassau or Suffolk, had the strongest growth rate (+2.90 percent) over the same time period. Thus the rate of income growth for the Town of Southold is strong. Over the study period to the year 2003, it is anticipated that income in the Town of Southold will continue to grow at a faster rate than the Long Island Region or Suffolk County. Between 1970 and 1980, double-digit inflation was the rule rather than the exception. The levels of absolute income were extremely high, resulting in large absolute changes in the median family income. For this forecast, using the Econometric Model of Long Island, the level of median family income for Long Island will approximate $46,303 by the year 2003. The Econometric Model of Long Island was developed by Prof. T. Conoscenti, Director--Division of Management, Polytechnic Institute of New York. (This assumes a 3.5-percent annual rate of change in the consumer price index.) For the Town of Southold, it is anticipated that the median family income will approximate $43,600 (Table 4-5 presents these calculations). This represents an average annual growth rate of 3.2 percent between 1980 and 2003. 4-10 i l i 1 t i I i. D-SOUTHOLD. 1/VTB4-5.1 08/17/84 Table 4-5.

Discussions with mortgage officers at a number of major Long Island banks (e.g., Long Island Trust Co., Norstar Bank, Nassau Trust Co.) suggest that, on the average, the median family income of second homeowners is two and one-half times that of permanent residents. Given the 1980 dates, the median income for second homeowners will approximate $53,000. Using a simple average, it is estimated that the combined median family income in 1980 was $37,000 per yeJr. To summarize, the recorded income for the Town does not reflect the true level of income, since it does not account for second homeowner residents. 4.3.1 Sources of Income The population of the Town of Southold derives approximately 55.7 percent of its income from wages, salaries, and proprietors' income, compared to either Long Island or Suffolk County, which derive over 84 percent of their incomes in the same manner. The lower percentage point difference reflects the fact that almost one-half of the income is derived from nonproduction sources, which represent a stable environment for growth since expenditures patterns are consistent over time (Table 4-6). An interesting point to observe is that Southold, compared to the region or county, derives a higher percentage of its income from blue collar employment rather than white collar employment. Table 4-7 presents these findings. In a recent study of the Long Island Region (Long Island's Economic Outlook, 1984-1990), it is anticipated that by the year 1990, employment by place of work will grow by 2.5 percent, annually growing from an 4-12 i i I I I I I i D-SOUTHOLD. 1/VTB4-6.1 O811O184 Table 4-6.

This study was prepared by Prof. T. Conoscenti, Director--Division of Management, Polytechnic Institute of New York, in January 1984. Table 4-8 presents these calculatlons. For the forecast period, it will be assumed that the Region's growth rate between 1990 and the year 2003 will be 2.0 percent. The interesting observation to make is that by the year 1990, the services sector of the economy will be the largest single compooent of the Long Island economy. Table 4-9 presents some selected econometric assumptions. Table 4-10 shows this sector to account for over 55 percent of the total environment. For Southold, this means that as the Long Island economy transforms itself towards a service economy, so will the economic base of the Town of Southold. The implication is that white collar jobs will imcrease in the work force, resulting in a higher income base for the Town. 4.3.2 Tourist Industry In recent years, the tourist industry has played a significant role in the development of the Region's economy. A recent study released by the Long Island Tourist Convention Commission indicated that the tourist industry on Long Island will exceed $10.0 billion by the year 1990, growing at an average annual rate of 11.5 percent per year between 1984 and 1990. Table 4-11 shows these calculations. The study also indicated that the east end of Long Island will account for 40 percent of this total, or $4.0 billion. For Sonthold, the significance is that a good portion of this money will be spent in the Town, thus increasing the level of employment and income. 4.3.3 Economic Scenario The necessary economic conditions which must exist to produce an environment for aviation to exist and prosper do, in fact, exist in the Southold area. 4-15 o8/18/8~ Table 4-8.

Median income is expected to grow by 3.2 percent annually throughout the forecast period, reaching a level of $43,600 by the year 2003. Hbwever, as noted, the actual level of income will be higher due to higher income levels of second homeowners. In addition, throughout the forecast period, the sources of income for the population base will continue to shift away from blue-collar employment towards white-collar employment, especially in the service industries (i.e, retailing, wholesaling, personal and business services). As part of the service sector, tourism will play an important role in providing the transition from blue-collar jobs to service sector jobs. Although it is difficult to quantify the role a growing tourist base will have on the level of aviation activity, it can only be assumed that they are interrelated and will support each other during the forecast period. To conclude, the data and analysis presented herein indicate the Town of Southold will grow significantly by the year 2003. 4.4 GENERAL AVIATION SCENARIO The widespread acceptance of air transportation since the early 1960s and the country's increasing dependence upon air transportation for intercity travel has not been limited to common-carrier air transportation offered by the scheduled airlines and scheduled tormenter operators. On the contrary, general aviation, which encompasses all civil flying other than the scheduled services, now accounts for a significant number of aircraft and aircraft flight hours. Given the current state-of-the-art in the technology of small aircraft (i.e., fuel-efficient, light weight, etc.), it is expected that the level of the general aviation market will rise by the year 2003. The 4-20 I I I I ! I i I I I i I i i I SOUTHOLDi~5-DT. 1/4.8 5/29/8~ integration of these factors, coupled with national and local economic factors, will determine the anticipated levels of general aviation activity within Southold. General aviation activity, in broad terms, is determined by the number of based aircraft at the airport and by the number of transient aircraft utilizing the airport. The procedure employed to forecast general aviation activity is first to forecast the number of aircraft which will be based at the airport. The next step is to forecast the level of aircraft operational activity. 4.5 BASED AIRCRAFT AND GENERAL AVIATION ACTIVITY The number of aircraft based at an airport is one of the basic yardsticks of general aviation demand. A based aircraft is defined as being stored at the airport for an extended period of time. This figure is projected by first forecasting the number of actively registered aircraft in the region and then estimating the portion based at the subject airport. 4.5.1 Aircraft Ownership An investigation of the availability of general aviation facilities revealed that in the towns surrounding Southold, there are 13 general aviation airports housing 874 based aircraft. In the Town of Southold, there are three airports with a total of 28 based aircraft. These aircraft represent approximately 3.2 percent of the total aircraft based in the vicinity. Table 4-12 presents these findings. Since the level of based aircraft in Southold is small relative to the total, it is necessary to forecast the relative levels of registered aircraft for the region and then relate this forecast to the Town of Southold to determine the number of potential based aircraft. Although the objective of this study is to determine the anticipated activity in the Town of Southold and not that of the region, close coordination between this study and the ongoing Downstate New York 4-21 i !

This coordination is considered essential in that the Town of Southold falls within the Downstate New York GASP Study Area. The GASP Study utilized a number of different methodologies in forecasting the Downstate area's regional requirements, each yielding different levels of aviation activity. The forecast that will be utilized in this study represents constant market share projections. results of this forecast are shown in Table 4-13. The By the year 2005, it is anticipated that there will be approximately 4,443 registered aircraft. This represents a 3.1-percent average annual growth rate over 1985. 4.5.2 Southold Based Aircraft Several factors influence an owner's decision as to where his aircraft should be based (stored). A recent survey conducted by the U.S. Department of Transportation revealed that the most influential factor is accessibility. Other significant factors are the quality of the airport, the quality of fixed based operators, airport and FBO prices, and aircraft operational requirements. During the GASP's base year (1982), there were 23 aircraft based at the sole public use airport (Mattituck) in Southold Town proper. Using this figure as a basis for their forecast, the GASP Study estimated the number of based aircraft at Southold's public use airport to rise to 45 by the year 2005. These levels of based aircraft are shown in Table 4-14. This represents an increase of 3.1 percent growth per year between 1982 and 2005. The forecast is based on the assumption that the number of based aircraft in Southold will grow at the same rate as the region (i.e., 3.1 percent per year for the region; 3.1 percent per year for the airport). 4-23 I i i i i i i i D-SOUTHOLD, I/VTB4-13.1 08/10/84 Table 4-13.

As part of the survey, members of the North Fork Aviation Association (NFAA) were surveyed, in addition to other potential users of the airport. The results of the survey have been discussed in the previous section of this report. However, of the 49 respondents, 24 individuals did own aircraft (some own more than one aircraft). Of the total 36 privately owned aircraft reported, only 12 aircraft are based in Southold. Of the remaining 24 aircraft, 13 aircraft would be relocated to Southold if adequate facilities were available. A discussion with members of the NFAA indicated that the primary reason for their not basing their aircraft in the Town of Southold was that the Mattituck Airport has limited facilities and is closed after dark. Assuming that a new airport facility would provide solutions to these shortcomings, then the total level of aircraft based at a new airport in Southold in 1984 would approximate 33 aircraft (Table 4-15). This assumes that relocation of aircraft would occur (according to the survey results) from other airports to Southold. It should also be noted that of the 23 aircraft currently based at Mattituck, the owners of approximately one-quarter of them have indicated that they would remain there. Since the questionnaire primarily surveys the Southold area, it is most likely that others would relocate their aircraft to Southold especially during the summer months when population increases. Considering that the economic base of Southold is expected to grow faster than that of the region and using both 33 based aircraft as the initial count and the previously discussed econometric model of Long Island, it is estimated that the growth rate of based aircraft at the proposed Southold Airport 4-26 I I I I I I i I D-SOUTHOLD.I/VTB4-15.1 08/10/84 Table 4-15.

This parallels the economic discussion in the previous subsection, with corresponding economic assumptions. 4.5.3 Based Aircraft by Type The base year mix of aircraft ownership was identified by reviewing the master aircraft registration file. A forecast of individual aircraft was then prepared by extrapolating the 1984 trend of individual aircraft types and by assuming that the current mix of aircraft will change towards slightly larger and faster (multi-engine) aircraft during the planning period. By the year 2003, it is anticipated that the aircraft mix at the new Southold Airport would consist of 90 percent single-engine aircraft, 4 percent helicopters, and 6 percent multi-engine aircraft. This translates into a mix of 60 single-engine aircraft, 3 helicopters, and 4 multi-engine aircraft. Table 4-17 presents the based aircraft fleet mix. 4.5.4 Aircraft Movements The total number of general aviation aircraft movements at Southold Airport is comprised of aircraft movements performed by based aircraft and those performed by transient aircraft. These movements are further classified as itinerant or local aircraft movements. Itinerant movements are landings and takeoffs performed by aircraft in transit between Southold and another airport. Local movements are those landings and takeoffs associated with training or sightseeing flights. Table 4-18 presents the projections of general aviation activity in terms of local and itinerant aircraft movements. Due to the lack of available historical data, the development of an integrated analysis for projecting operations and fuel usage is inappropriate because neither the inputs nor the results can be verified.

This model revealed that the number of itinerant movements performed by transient aircraft equals the number of itinerant movements performed by based aircraft multiplied by 1.5 for each aircraft type. Appendix D outlines the general specifications of the General Aviation Aircraft Movements Model. Table 4-19 presents the estimated base year operations and forecast of aircraft movements at Southold Airport. Table 4-20 shows the forecast of activity by type of aircraft and type of operation. Total general aviation aircraft movements are forecast to be 16,900 movements by 1988. By 1993 this is expected to rise to 20,700 movements, and by the year 2003 to a level of 31,500 per year. The long-run forecast of total movements represents an average long-run annually compounded growth rate of 4.2 percent. 4.5.5 Terminal Area Relationships Terminal area relationships were calculated based on survey data from other similarly sized airports in the Northeast. This information revealed that approximately 11.4 percent of general aviation itinerant operations, and 12.6 percent of general aviation local operations, occur during the peak month of the peak season annualized. Additionally, FAA survey data reveal that approximately 10 percent of local activity, and 9 percent of itinerant activity, occur during the peak hour of the average day of the peak month. The above-mentioned relationships are applied to the annual forecasts_ as a basis for preparing the general aviation terminal area relationships.

However, the need to evaluate commercial activity is apparent in view of the fact that many general aviation airports are serviced by small'air taxi operators. In the case of Southold, air taxi operators do serve the area from as nearby as 20 miles away (across the Long Island Sound in New London) to as far away as points in New Jersey. There are four air taxi operators which currently serve the Southold area: Action Air, Coastal Air, New England Airlines, and Yankee Airways. These operators were contacted to provide estimates of air taxi activity at the proposed Southold Airport. 4.6.1 Aircraft Operations At present, there are an average of 36 operations (landings or takeoffs) per day during the summer months and 6 operations per day during the winter months. Yankee Airways has served the area for the longest period of time with the other operators coming into the marketplace within the last 3 years. Since no historical records exist pertaining to this activity, any detailed analysis would be inappropriate. However, discussions with Yankee Airways and ESE internal staff analyses suggest that if a new airport is built, the number of operations per day would most likely grow at a rate of approximately 5 percent per year throughout the forecast period. By the year 2003, winter operations are anticipated to reach a level of 16 per day, and summer operations are expected to increase to a level of 95 per day. Assuming a daily operational level of 16 during the off-season (November-April), the total number of operations for this 6- month period would increase to 2,900 in 2003. Similarly, the 6-month peak season (May-October) would yield 95 daily operations which translates into 17,300 total operations. Thus, it is projected that in 2003, the proposed Southold Airport will handle 20,200 annual operations I I 4-35 I I I I I ! I I SOUTHOLD85-DT.1/4,14 6/10/85 by commuter/air taxi aircraft. Ail of these operations are expected to be conducted by light twin-engine aircraft. The projections of potential commuter/air taxi activity are presented in Table 4-21. 4.6.2 Passenger Enplanements As previously discussed, it is expected that all commuter/air taxi operations will be conducted by light twin-engine aircraft. The seating capacity of typical aircraft is 6 seats (i.e. Piper Navajo, Beech Baron, Cessna 402, Piper Twin Comanche, etc.). It is further assumed that the typical load factor for air taxi operators flying these aircraft types averages 60 percent. Thus, the resulting average enplanements per departure is 3.6 passengers. The forecast of passenger enplanements on commuter/air taxi aircraft is presented in Table 4-22. 4.6.3 Terminal Area Relationships Statistical trends of the commuter/air taxi industry in terms of peaking factors were analyzed to determine aircraft terminal area relationships. This analysis revealed that approximately 10 percent more operations th~n the level of the peak season operations occur during the peak month (most likely August) and it is estimated that about 20 percent of average day operations occur during the peak hour. These percentages were applied to the forecast of aircraft operations to arrive at a forecast of commuter/air taxi terminal area relationships (shown in Table 4-23). Total passenger terminal area relationships were calculated in a similar manner. 4.7 INSTRUMENT ACTIVITY Table 4-24 presents the forecast instrument operations and approaches at the proposed Southold Airport. Since there is no history, the activity projected in this forecast represents a potential that could be realized should the Airport be equipped with an approach NAVAID.

An instrument operation may occur in visual (VFR) as well as IFR conditions. An instrument approach, on the other hand, is an IFR approach made under actual IFR weather conditions. For purposes of this analysis, it was assumed that the North Fork experiences VFR conditions 83.5 percent of the year, IFR conditions approximately 12 percent of the time on an annual basis, and "below minimums" approximately 4.5 percent of the year when the Airport would be closed. The above percentages, which are rounded, are based upon the combined meteorological analysis of conditions at Suffolk County and Tweed-New Haven Airports, as discussed in Section 3. It was further assumed that the minimums for a nonprecislon instrument approach at Southold Airport would closely resemble those at Calverton with its VORDME approach to Runway 32. Calverton's minimums with this NAVAID are a cloud ceiling of 580 feet above mean sea level and visibility of 1 mile. By applying the forecast level of operations to the above weather characteristics on the North Fork, annual instrument operations and approaches were estimated for each of the forecast years as shown in Table 4-24. 4.8 FUEL FLOWAGE Fuel flowage refers to the number of gallons of aviation fuel projected to be sold at Southold Airport. The forecast of fuel flowage is provided to allow projections of future airport revenues. Since historical fuel flowage data for Southold is not available, certain assumptions have been made. The fuel flowage figure for 1988 and throughout the planning period was estimated based on the assumption that aircraft purchase an average of 5 gallons per departure. This figure is based upon the fuel consumption statistics at other local airports (i.e., Brookhaven, East Hampton, and Suffolk County Airports). The fuel burn by aircraft type and the percent purchased at the base airport were obtained 4-40 I ! I I I I I I SOUTHOLD85-DT. 1/VTB4-21 . 1 6/10/85 Table 4-24.

I SOUTHOLD85-DT.1/5.1 6/10/85 5.0 DEMAND/CAPACITY ANALYSIS AND FACILITY REQUIREMENTS Having established demand parameters for the proposed Southold Airport, in terms of potential traffic projections, the capacity and sizing of needed aviation f~cilities can be calculated. These computations are then compared to the anticipated demand to determine the extent of development of the various airport components. Projections of potential aviation demands have been set forth in Section 4.0 (Forecast of Aviation Demand). The following section presents the capacity of various airport facilities needed to accommodate this demand and recomendations for providing these facilities. Capacity requirements have been determined for the following three aspects of the proposed Southold Airport: (1) the landing area, (2) the terminal and support area, and (3) airspace and navigational aids. Additionally, a discussion on the viability of and need for establishing a publicly owned airport in the Town of Southold precedes the presenta- tion of capacity requirements. The capacity calculations, based upon various forecast components, should be regarded as generalized planning tools which assume attainment of forecast levels. Should the forecast prove conservative, proposed development should be advanced in schedule. Likewise, if traffic growth materializes at a slower rate than forecast, deferral of expansion would be prudent. 5.1 AIRPORT ROLE The surveys of potential users of the proposed airport conducted as part of this study and discussed in Section 3.0 identified various aircraft types that intend to utilize the Town airport. In addition, these surveys served to demonstrate that both the local aviation community and the business sector strongly support a Town-owned airport. Both sectors I ! 5-1 ! I I I I I I I I i I I I I SOUTHOLD85-DT. 1/5.2 6/lO/85 stated that the facility is needed and would serve to promote tourist, business and aviation activity in the Town of Southold. However, this activity should be balanced so as not to jeopardize the environmental quality present in Southold. Thus, the role of the airport should carefully consider both concerns. Based upon the surveys, it is expected that single-engine aircraft will be the primary users of the new Southold Airport; however, it is anticipated that the facility will also be utilized by some helicopters and light twin-engine aircraft. According to FAA Advisory Circular 150/5300-4B, dated September 23, 1983 (Utility Airports--Air Access to National Transportation), there are four types of utility airports. Since it is expected that Southold's airport should be designed for small twin-engine aircraft (i.e., Piper Navajo, Cessna 402, Beech King Air, etc.), the airport should ultimately conform with the standards of a General Utility-Stage I airport. Based on FAA's definition, as discussed in AC 150/5300-4B, the proposed airport should serve ". . . all small airplanes. Precision approach operations are not. usually anticipated. This airport is also designed for small airplanes in Airplane Design Group I." Initial development plans should be designed to meet the criteria of a Basic Utility-Stage II airport, which according to FAA AC 150/5300-4B," · .accomodates the airplanes of Stage I (75 percent of the single-engine and small twin-engine airplanes used for personal and business purposes), plus a broader spectrum of small business and air taxi-type twin-engine airplaines." The Town of Southold has stated that the proposed airport should be capable of accommodating only small general aviation aircraft types, which includes all single-engine and light twin-engine aircraft. The Town's position is also to restrict operations by jet aircraft, which is possible by the availability of facilities that are only capable of accommodating smaller aircraft (i.e. no jet fuel, limited pavement I I 5-2 I I I I i I I i I I I I i I SOUTHOLD85-DT. 1/5.3 6/10/85 strength, limited runway length, etc.). It is also possible to prohibit jet aircraft by stating that the facility is "closed to jet-powered aircraft without prior permission" in the appropriate pilot flight manuals (i.e. Jeppesen Airway Manual). 5.2 AIRSIDE FACILITIES The airside facilities at the new Southold Airport consist of any facilities specifically intended to accormodate arriving and departing aircraft and their access to or from the active landing strip. Typically, these facilities include the runway, taxiing routes, and navigational aids. This section presents a discussion of these specific facility requirements at the new airport. 5.2.1 Airfield System Capacity The capacity of a given airfield system is dependent on its basic configuration, on the type and mix of aircraft, and on system usage. Inherent to the concept of capacity is the assumption of acceptable delay in accommodating aircraft demand. To understand fully the magnitude of potential demand and probable capacity at the new Southold Airport, a typical airfield configuration was assumed. The basic layout consists of a single runway with a single taxiway access route at the approximate midpoint of the runway. In addition, it was assumed that neither an instrument landing system nor radar coverage would be available at the new airport. Other assumptions that have been made based upon FAA Advisory Circular 150/5060-5, Airport Capacity and Delay, dated September 23, 1983, include the following: the airport is used exclusively by single-engine and small twin-engine aircraft, arrivals are equal to departures, and touch-and-go activity constitutes approximately 20 percent of the total activity. It is felt that the previously mentioned assumptions would reasonably approximate the Southold Airport situation in terms of airfield capacity. I I 5-3 I I I I i I, I I SOUTHOLD85-DT.I/5.4 6/10/85 FAA AC 150/5060-5 states that this airport configuration is capable of accommodating between 59 and 72 operations per hour during visual flight rules (VFR) conditions and between 20 and 24 operations during instrument flight rules (IFR~ conditions. VFR conditions are typically declared when weather permits a minimum visibility of 1 mile and a cloud ceiling of 1,000 feet above ground level. IFR conditions are representative of inclement conditions, which are below the above minimums, when the use of instruments in the cockpit of the aircraft are required. Utilizing the FAA's annual capacity methodology, the new Southold Airport should be capable of accommodating approximately 183,000 operations on an annual basis. Therefore, it is important to note that no airfield capacity constraints can be expected at the new airport during the first 20 years of its life and, assuredly, well beyond that point. This statement is made based upon the forecast of activity presented in the year 2003 (51,700 total aircraft movements). This level of activity is only 28 percent of the total airfield capacity. Thus, no airfield facilities are warranted at the new Southold Airport for capacity 5.2.2 Runwa7 Length Runway length is a critical consideration in airport planning and design. Aircraft need specified runway lengths to operate safely under varying conditions of wind, precipitation, temperature, and takeoff weight. The FAA publication Utilit~ Airports--Air Access to National Transporta- tion, AC 150/5300-4B (dated September 23, 1983) contains criteria utilized in developing the runway length requirements needed to accommo- date the smaller types of general aviation aircraft. The recommended runway lengths are based upon performance curves developed from FAA- approved flight manuals. Runway length curves for General Utility-Stage I airports were used in this analysis for the ultimate runway length requirements. The initial runway length was determined by ! ! 5-4 I I i I I I I I I I I i I I SOUTHOLD85-DT. 1/5.5 6/10/85 evaluating the curves for Basic Utility-Stage II airports. Runway lengths were developed based upon a mean maximum temperature of 86° Fahrenheit and an approximate airport elevation of 50 feet above mean sea level (MSL). This resulted in a runway length requirement of 3,000 feet in the initial development stage and ultimately 3,600 feet for the new Southold Airport. d runway with this length is capable of accommodating the following typical aircraft types: 1. Piper Twin Commauche, 2. Beech Baron, 3. Cessna 402, and 4. Piper Navajo. Two of the survey respondents own aircraft of the types previously mentioned; thus, it is recommended that the airfield configuration at the new airport include initial plans of 3~000 feet with the capability of being extended to a 3,600-foot runway. Operations by larger twin-engine aircraft than those identified above are expected to be on an infrequent basis. Therefore the critical aircraft types are considered to include' the types listed. Based on criteria set forth in FAA AC 150/5300-4B for the length of a crosswind runway, if it is determined that Southold's airport needs a second runway and if it is feasible at the recommended site, it should be at least 80 percent of the length of the primary runway. In light of the recommendation for a 3,600-foot length for the primary runway, the crosswind runway at Southold should be at least 2,880 feet in length (2,400 feet initially to coincide with a 3,000-foot runway length). Thus, if a crosswind landing strip is warranted at the proposed Southold Airport to meet FAA criteria, as noted in the above Advisory Circular, of 95-percent annual wind coverage with a lO.5-knot crosswind, it is recommended that this runway be built at an ultimate length of 2,900 feet. ! m 5-5 I I i I I I I I I I I i i I SOUTHOLD85 -DT. 1 / 5.6 6/lO/85 5.2.3 Runway Width FAA AC 150/5300-4B specifies certain minimum dimensions, clearances, and separation standards for the design of utility airports. A minimum runway width of 60 feet is recommended for visual and nonprecision runways that are expected to serve aircraft with a wingspan of less than 49 feet (Airplane Design Group I). In that it is expected that the new Southold Airport will be equipped with a nonprecision instrument approach, rather than precision instrument approach capabilities, it is recommended that the runway be constructed at a width of 60 feet. 5.2.4 Pavement Strength In light of the fact that the proposed Southold Airport is intended to serve only smaller general aviation aircraft, it is recommended that the pavement be designed to accommodate these aircraft. FAA AC 150/5300-4B indicates that a pavement strength of 12,500 pounds is recommended for General Utility-Stage I facilities. As such, a pavement strength of 12,500 pounds is recommended for the proposed Southold Airport. The two most critical aircraft, in terms of weight, that are expected to operate at the new airport both weigh less than 12,500 pounds. The Beech Baron's maximum takeoff weight is 6,200 pounds and the Piper Navajo is listed at 6,500 pounds, according to FAA AC 150/5300-4B. 5.2.5 Runway Orientation Crosswind runway requirements are a function of aircraft performance, crosswind components, and the desirable percentage of wind coverage. Planning guidelines suggest that when the need for a crosswind runway is evaluated, a maximum crosswind component of 10.5 knots (12 miles per hour) should be used for basic and utility-type aircraft and 13 knots (15 miles per hour) for transport and air carrier aircraft. Since it is expected that the $outhold Airport will only need to accommodate smaller ! I 5-6 I I I I I I I I SOUTHOLD85-DT.1/5.7 6/lO/85 aircraft types, a 10.5-knot crosswind component is appropriate. Further, according to FAA AC 150/5300-4B, sufficient runways of different orienta- tions should be planned to ensure that the airport achieves an annual all-weather wind coverage of at least 95 percent with a lO.5-knot crosswind. As presented earlier in Section 3, the predominant wind orientation is from the southwest during both VFR and IFR weather conditions. A runway alignment of northeast-southwest (04-22) was first tested to determine its annual wind coverage. Under "all time periods," this orientation provided 85.89-percent wind coverage, which is well below the FAA standard of 95 percent. The next test direction evaluated was southeast-northwest (13-31), which increased the annual wind coverage slightly to 86.62 percent. The final runway alignment which was considered was a south southeast-north northwest (15-33) direction, which resulted in an 86.14-percent annual wind coverage. The conclusion which can thus be reached is that there is not one runway alignment that will provide an airport on the North Fork with the recommended 95-percent wind coverage. Further, it appears that based on "all time periods," which includes VFR, IFR, day, night, and all seasons, the orientation of the primary runway is flexible; however, it should be noted that the proposed Southold Airport should consider plans for a two-runway configuration to provide the needed wind coverage if feasible. It appears that the two best alignments for Southold's airport are southeast-northwest (13-31) and northeast-southwest (04-22), which provide a total wind coverage of 98.17 percent on an annual basis. In order to maximize wind coverage it is recommended that the new Southold Airport consist of two intersecting runways with the previously discussed orientations. However, if this is not possible for other site specific reasons (i.e. land availability, cost factors, etc.), a single runway providing optimal usability is suggested. I I 5-7 I I I I I I I I SOUTHOL~SS-BT.1/5.8 6/10/85 Since there is only a marginal difference between the amount of wind coverage provided by the two above alignments (04-22 and 13-31), further weather analyses of wind coverage during inclement (IFR) weather condi- tions and peak season (s,,,nmer) were conducted to assist in the determina- tion of the best runway direction. If one direction provides a signifi- cant advantage in terms of coverage during IFR conditions and the peak summer season, the provision for instrument approach capabilities should be considered on that runway. Since the primary runway is recormnended to be 700 feet longer than the crosswind runway, it is advisable that the instrumented runway have the extra length and, thus, be designated as the primary runway. Likewise, if a single runway configuration proves to be most viable, a determination of which end of the runway should be designated as the primary end is also necessary. The IFR weather evaluation resulted in a determination that the predom- inant wind direction during inclement conditions is from the southwest. However, the combined coverage of NNE, NE, and ENE is better than that of the opposite end (SSW, SW, and WSW). In fact, the 04 end provides 10.11 percent IFR wind coverage versus 9.34 percent on the 22 end. For comparison purposes, the 13-end provides 9.14-percent wind coverage during IFR weather, while the 31 end only provides 8.37 percent. Ail of the above percentages include 4.01-percent calm wind conditions. The analysis of wind conditions during the summer peak season also revealed that a NE/SW orientation would prove the most usable (SW being the predominant direction). The second most feasible alignment for summer winds is NW/SE, with the predominant orientation to the NW. Based on this analysis, it is thus recommended that the northeast- southwest (04-22) runway be designated as the primary runway with the Runway 04 end equipped with instrument approach capabilities. However, if a single runway configuration is planned with the runway oriented NW/SE, the end thaf should be designated as the instrument runway is 5-8 I ! I I I I I I I I I I I I SOUTHOLD85-DT.I/5.9 6/10/85 Runway 13 (SE) to account for IFR winds originating more from the south- east than from the northwest. Therefore, the recommendation being set forth is that the primary runway (04-22) should be constructed with an overall length of.3,600 feet. It is also recommended that the crosswind runway, 13-31 (southeast-northwest), be constructed at a length of 2,900 feet. Further, if a SE-NW runway is the only runway proposed at the Airport, it should be planned for an ultimate length of 3,600 feet. 5.2.6 Taxiway Requirements As discussed in Section 5.2.1, the proposed Southold Airport does not need any airfield facilities for capacity reasons in that its capacity rating with just a single runway is well in excess of its requirements. However, from a safety standpoint, it might prove desirable to construct a parallel taxiway on the primary runway. For ultimate planning purposes, a parallel taxiway is also suggested on the crosswind runway. This type of improvement will serve to permit taxiing aircraft to do so off of the active runway. Without a parallel taxiway, a landing aircraft will need to hold away from the Airport and delay initiating its final approach until the active runway has been vacated. Thus, based upon the Airport's final configuration, a parallel taxiway should be considered on the primary runway at the outset and in later planning phases on the crosswind runway, if it is paved. If such a taxlway is established, it should be constructed with an overall width of 25 feet and with a runway centerline-to-taxiway centerline separation distance of 150 feet. These dimensional standards are recommended in FAA AC 150/5300-4B. 5.2.7 Airfield Separation Criteria FAA Advisory Circular 150/5300-4B sets forth separation criteria for a number of airfield components. Since the proposed Southold Airport is expected to ultimately comply with the standards of a General Utility-Stage I airport, the airfield separation criteria of a General Utility-Stage I should also apply. These standards are outlined in Table 5-1. I i 5-9 I I I I I I I I SOUTHOLDS5-DT. 1/VTB5-1.1 5/29/85 Table 5-1.

The minimum land requirements of typical utility airports is addressed in FAA AC 150/5300-4B, which can serve as a useful guide in identifying potential airport sites of adequate size. For a single-runway General Utility-Stage I airport with an overall runway length of 3,600 feet, the total minimum land requirement is 100 acres. This acreage is broken down as follows: 1. Forty-six acres for landing area (runway and required safety areas)~ 2. Thirty acres for approach areas (clear zones, noise zones, etc.), and 3. Twenty-four acres for building areas (hangars, aprons, auto parking, etc.). As discussed in Section 5.2.5, for an airport on the North Fork to meet the FAA criteria of 95-percent annual wind coverage, two intersecting runways are needed. The additional land requirement for a 2,900-foot crosswind runway is 62 acres (30 acres for the approach area and 32 acres for the landing area). Thus, the minimum land requirement for the proposed Southold Airport is 162 acres, assuming a 3,600-foot primary runway and a 2,900-foot crosswind runway. If due to site specific land constraints, a two-runway configuration is not feasible, the viability of a short turf crosswind runway should be considered. 5.2.9 Airspace and Navigational Aids Analysis of the airspace environment relative to a new airport on the North Fork revealed no problems or restrictions under VFR conditions in that all existing facilities are sufficiently removed from the Town of Southold. Under IFR conditions, the interaction of approach airspace 5-11 I I I I I I I I I I I I I I I SOUTHOLI)85-DT.1/5.11 6/10/85 areas with other airports utilizing the same navigational aid results in simultaneous approaches. Additionally, as previously discussed, an airspace conflict during IFR conditions with Suffolk County Airport is possible. However, due to present and anticipated low levels of instrument approach activity, the severity of the problem is reduced. Airport construction and/or abandonment in the vicinity of the Town should be continuously monitored to ensure that no unexpected airspace interactions occur in the future. On an annual basis, according to the meteorological analysis conducted as part of this study, IFR weather conditions exist on the North Fork 16.53 percent of the time. In accordance with annual instrument approach (AIA) criteria stated in FAA Order 7031.2B (Airway Planning Standard Number One--Terminal Air Navigation Facilities and Air Traffic Control Services) and the forecast of AIAs presented in Section 4.5.5, the proposed Southold Airport would not qualify for a precision instrument landing system. However, in light of the high percentage of IFR weather that is typical of Long Island, it is recommended that the new Southold Airport be equipped with a nonprecision instrument approach. Since there are a number of existing VOR facilities in the area (CCC and HTO on Long Island and MAD across the Sound in Connecticut), it should be no problem to establish at least a circling approach, if not a straight-in instrument approach procedure. Nonetheless, it is recommended that FAA conduct an investigation of the feasibility of a nonprecision instrument approach and the procedures needed to utilize such an approach at the Town airport. To allow the new Southold Airport to be usable after sunset, it is recommended that initially the primary runway be equipped with medium-intensity runway edge lighting (MIRLs) and that ultimate plans include MIRLs on the crosswind runway, if it is paved. It is further recommended that in the initial development stage, both primary runway ends be equipped with Runway End Identifier Lights (REILs). This recommendation is made based upon the qualifying criteria set forth in I I 5-12 I I I I I I I ! I I I I I I SOUTHOLD85-DT. l / 5.12 6/~0/85 FAA Order 7031.2B, as amended, that a runway end would be eligible for REILs if it handled at least 1,200 air taxi landings per year. It is expected that Southold Airport's primary runway end will reach the 1,200 level in its initial year of operation (forecast projects in excess of 4,900 air taxi landings in 1988). Based upon the forecast of aviation activity and current FAA criteria, the proposed Southold Airport would also be eligible for a visual approach slope indicator (VASI) system on both ends of the primary runway in the initial development stages. It is further recommended that the Airport be equipped with a rotating beacon. 5.3 LANDSIDE FACILITIES The following discussion deals with the landside elements of the proposed Southold Airport. Landside facilities are typically the buildings, paved areas, and associated infrastructure that acconnnodate users of the airport. The landside components together with the previously discussed alrside elements form all of the airport development facilities required to accommodate the forecast level of activity. Since the airfield development program has been based on an ultimate level of some 51,700 annual operations at the proposed Southold Airport, the planning of landside facilities should be based on striking a balance of airside and landside capacity. The determination of landside facilities for Southold Airport has been accomplished for the three future planning periods of 1988, 1993, and 2003. It should be noted that some provisions are needed for commuter/air tax~ activity, as noted in the following discussion. 5.3.1 Administration/Terminal Buildin~ The focal point of activity at a typical general aviation airport is the Fixed-Base Operator (FBO). An individual FBO may provide from one to several services to airport users, including: (1) fuel, (2) aircraft maintenance, (3) air taxi/charter, (4) aircraft rental, (5) flight instruction, and (6) sale' of pilot necessities. In some cases, the FBO I I 5-13 I ! I I I I I I I SOUTHOLD85-DT. 1/5.13 6/10/85 may also manage, operate, and maintain the entire airport. Various airport management options will be evaluated in a subsequent portion of the study. Since a decision on the most desirable form of airport management has not been reached, FBO management will be considered. Under this type of arrangement, the FBO functions as a terminal, serving as the transfer point between air and ground transportation modes, and at times, also as the airport administrator. To fulfill this role, a centrally located multifunctional building is needed to accommodate waiting pilots and passengers, space for flight planning, management and operations area, public conveniences, and concessions. These structures are often built in conjunction with larger buildings or in proximity to the FBO's facilities. The amount of terminal building space required is a function of the expected peak demand (i.e., the peak hourly volume of pilots and passengers that are expected to use the facility). The planning standard of 49 square feet per peak-hour pilot/passenger is then applied to the number of peak-hour itinerant pilots/passengers to determine the required building area. Table 5-2 presents the breakdown of the 49-square-foot planning standard. Applying the factor of 49 square feet to the projected level of busy-hour passenger activity, as derived in Table 5-3, a terminal and operations building of 1,029 square feet in size is needed initially. In light of the expected growth of activity once the Airport establishes itself as a viable aviation facility, the terminal building will require an expansion of 1,000 square feet so that an ultimate floor area of 2,156 square feet is available. This facility has been sized to efficiently accommodate both commuter/air taxi and general aviation users during the peak summer 5-14 ! ! Table 5-2.

In Southold's case, the factor that has been utilized in determining automobile parking requirements assumes that 1.3 spaces should be provided for peak hour passengers. This factor accounts for full utilization by peak-hour passengers (100 percent), and use by visitors and employees (30 percent), which results in a factor of 130 percent. It should be noted that one parking space covers an area of 320 square feet. The evaluation of automobile parking space requirements is presented in Table 5-4, which shows that, at the end of the study period in the year 2003, Southold Airport will need an auto parking lot covering an area of 18,240' square feet. An automobile parking lot of this size is capable of accommodating 57 vehicles. The initial size of the parking lot has been determined to cover an area of 8,640 square feet, which has a capacity of 27 automobiles. 5.3.3 Aircraft Parking Apron A sufficient amount of aircraft parking space must be provided in the vicinity of the terminal building for transient aircraft, as well as commuter/air taxi aircraft and a limited number of based aircraft. Table 5-5 presents space requirements for the aircraft parking apron based on the assumptions discussed below. The Forecast of Aviation Demand (Section 4) identified the number of transient aircraft and commuter/air taxi aircraft that can be expected to be on the ground on the average day of the peak month (ADPM) during the study period. Using this as a base, the following certain assumptions were made and applied to this activity to determine apron space requirements. 5-17 I ! I I I I I I SOUTHOLDSS-DT.I/VTBS-4.1 5/29/85 Table 5-4.

The majority of these transient and commuter/air taxi aircraft will arrive and depart on the same day. Therefore, it is assumed that the actual number of peak day transient aircraft is one-half of the transient activity; 2. During the peak period, 50 percent of the transient aircraft and 25 percent of the commuter/air taxi aircraft will be on the ground at any given time; 3. Thus, 25 percent of the ADPM transient activity and 12.5 percent of the commuter/air taxi activity will need parking space; 4. Five percent of the based aircraft will be parked temporarily on the terminal apron at any given time; and 5. Single-engine aircraft require 2,700 square feet, and multi-engine aircraft need 5,625 square feet of apron space for parking and maneuvering. As can readily be seen from Table 5-5, there is a present need for a transient aircraft parking apron at Snuthold Airport of 44,550 square feet. This apron should cover an area of this size to adeqoately accommodate the demand on the average day of the peak month, which is considered to be a satisfactory figure for planning purposes. The transient aircraft parking apron should continually be expanded so that by the end of the study period, in the year 2003, it should offer nearly 95,000 square feet of paved parking space. 5.3.4 Based Aircraft Storage Typically, airports that serve the general aviation sector offer both hangar and tie-down storage for based aircraft. There are two types of tie-down aprons normally used by airports, paved and turf aprons. Due to the relatively high frequency of inclement weather conditions in the northeast, paved tie-down space is much more common than onpaved. Therefore, it is recommended that Southold Airport provide paved aprons for based aircraft tie-down. There are also two forms of hangar storage 5-20 I I I I I I I I I I I I I I SOUTHOLD85-DT.1/5.16 6/10/85 space, T-hangar and conventional. A typical general aviation airport offers a combination of both, and therefore, it is recommended that Southold do the same at its proposed airport. According to the forecast of based aircraft demand at Southold Airport, the number is expected to increase from its anticipated 1988 level of 36 aircraft to 67 aircraft in the year 2003. Adequate storage facilities should be provided to accommodate the various based aircraft forecast levels. The demand for hangar storage of based aircraft at Southold Airport should be greater than the national average at general aviation airports due to the relatively colder, more inclement weather conditions that are typical of the Northeast. Based on this, the following assumptions were made in determining the need for the various types of storage: o Forty percent of the based single-engine aircraft would use a tie- down space. Fifty-five percent of the total would be stored in T- hangars, and the remaining five percent would use conventional hangar storage space. Eighty percent of the multi-engine aircraft based at Southold would be stored in hangars. Sixty percent of these (48 percent of the total) would use T-hangars, and 30 percent of these (32 percent of the total) would be stored in conventional hangars. Tha remaining twenty percent would utilize tie-down space. The based aircraft storage requirements were computed by utilizing the assumptions presented in Table 5-6 and are summarized in Table 5-7. Aa can be seen from Table 5-7, Southold Airport will need the following facilities for based aircraft storage at the outset of its operation: I I 5-21 I ! I I I I ~-SOUT~OLD. 1/V~5-6, 1 Table 5-6.

The above storage facilities will be in need of expansion as activity increases at Southold Airport. It is expected that, in the year 2003, an area covering in excess of 73,000 square feet will be needed for tie-down space, a total of 37 T-hangar spaces will be warranted, and an aircraft storage hangar with a total floor area of just over 8,000 square feet will be required. 5.3.5 Fuel Storage Facilities A forecast of annual fuel flowage was presented in Section 4.5.6 of this report. An analysis of the monthly fuel requirements of 100-octane fuel was conducted and is presented in Table 5-8. This analysis was based on relating forecast fuel sales to the peak activity associated with it at other typical general aviation airports with seasonal variances. It wa~ assumed that twice as much fuel will be sold in the warm weather months (May to October) as in the other months of the year. Table 5-8 shows that, in the year 2003, storage capacities of more than one month of 100 octane are possible with the installation of a 10,000- gallon underground fuel tank. In order to provide surplus fuel storage capacity, consideration should be given to installing a second 10,000 gallon underground fuel tank. Since it is expected that aircraft activity at Southold will be limited to single-engine and light twin- engine aircraft, the need for jet fuel is not justified. Further, in order for the Town to limit or restrict operations by turbine-powered aircraft (jets), the unavailability of jet fuel will serve to discourage this type of activity.

They are located in Cutchogue, East Marion, Greenport, Mattltuck, Orient, and Southold. With the dispersed placement of these companies, the To~r~ is provided with excellent fire protection coverage. Likewise, it is quite possible for the airport site to be such that a response time of no more than 10 minutes can be expected. This type of fire protection is acceptable as a secondary means; however, on-airport capabilities are recommended for quick response protection. The Federal Aviation Admini- stration has developed recou~nended guidelines for such service and has outlined these criteria in Advisory Circular No. 150/5210-6B, Aircraft Fire and Rescue Facilities and Extinguishing Agent~, January 26, 1973. Under these guidelines and on the basis of expected operations, according to aircraft type, Southold Airport should comply with the requirements of an Index 1 airport. To meet these criteria, the Airport needs one vehicle with one of the three following capacity capabilities: 1. 200 gallons of water for foam production for aqueous film forming foam (AFFF) with a solution application rate of 150 gallons per minute, 2. 300 gallons of water for foam production for protein foam with a solution application rate of 230 gallons per minute, or 3. 300 pounds of dry chemical powder. Thus, provisions should be made to supply the Airport with one of the above capabilities once it becomes operational. 5.3.7 Aircraft Maintenance Facilities The demand for aircraft maintenance will increase as activity at Southold Airport grows. To a¢comodate this demand for aircraft maintenance, provisions should be made to provide this service. The sizing of aircraft maintenance facilities assumes that one maintenance space should be provided for every 10 based aircraft. For obvious reasons, the area 5-26 I I I I i I I I SOUTHOLD85-DT. 1/5.19 6/10/85 requirements for the various types of aircraft are greater than those needed for parking space. It has been determined by surveys conducted by PRC and ESE of fixed-base operators at various general aviation airports that single-engine aircraft require 3,200 square feet and multi-engine aircraft need 4,700 square feet of space for maintenance purposes. These area requirements allow for building clearances, apron area, and maneuvering area. Table 5-9 presents the results of this analysis. Initial requirements for aircraft maintenance should provide for an area (hangar and apron) of nearly 13,000 square feet. By 1998, the aircraft maintenance facilities should consist of a total area of approximately 16,000 square feet and should be further expanded so that, by the end of the study period in the year 2003, 19,200 square feet of hangar and apron area should be avail- able for aircraft maintenance services.

Twelve (12) sites throughout the Town were identified as candidate airport sites. These twelve sites are depicted in Figure 6-1 and are designated with number identifiers. A number of these candidate sites were previously considered as potential airport sites in earlier planning studies. Some additional sites have been included in this initial listing of candidate airport sites so as to not preclude any site that may prove feasible. The 12 initial sites were determined based on a review of available mapping material. This screening process, which was conducted by the consultant and representatives of the Town, included existing airports, any sites that were previously considered, and other sites that appeared to be potentially feasible. The rationale used to determine if a site was potentially feasible included: the availability of the site; remoteness of its location from concentrated areas of development; or its exclusion from the farmland preservation program. The 12 sites which were selected were considered to be representative of the full spectrum of potential sites across the entire township. Ail of the sites shown in Figure 6-1 conform as closely as possible to documented parcel boundary lines, which results in some of the sites having irregular shapes and varying.sizes. The next step was an evaluation of all potential sites so that a determination could be made of which sites could conceivably support an aviation facility. Each site is systematically reviewed in this section. In considering each location, its physical characteristics, environmental constraints, location with respect to neighboring sensitive uses, as well as ability to satisfy the target goals established in the facility requirements analysis were taken into account. The purpose is to eliminate those sites which unavoidably compromise one or more of the practical criteria which must be applied. This process is both judgmental as well as analytical. Its outcome is a 6-1 . ~~ .~~ ~ ,.' I .~ ~._~__I '.'" ~" ..' ,,,~z'"""'"~..~. b.L~ ~<, ~ ' "'~~,,'-~~.. jI~,'~'.

In sun~ary, this phase of the investigation will refine the available range of sites by eliminating those which are obviously undesirable relative to others that are potentially available so that detailed comparisons can be made between the most promising sites. 6.2 NOISE CONTOUR DEVELOPMENT Experience has shown that environmental impacts resulting from aircraft operations are important in determining whether any airport at all is acceptable in a specific region or township. This is particularly true in areas such as Southold where the overall level of environmental quality is high and the public at large is dedicated to its protection. Frequently, the overriding issue is aircraft generated noise. Clearly, it is desirable to direct aircraft traffic away from the more heavily populated community areas. Noise impacts at small general aviation airports are typically limited to the airport itself. Noise impacts at the proposed Southold Airport are consistent with this generalization. Detailed quantification of expected noise impacts are measured through the use of the Day-Night Average Sound Level (Ldn) measurement system. This methodology has been established by the Federal Aviation Administration as the single system for depicting noise impacts at airports nationwide. The Ldn system is based on the A-weighted decibel [dB(A)] which is the most common measure for environmental noise. A- weighting is simply a means of adjusting the measured noise level through an electronic network so that the noise meter approximates the frequency sensitivity of the human ear. Noise impact information for airports is often developed through the application of a computer.model which produces a series of nested contours of equal cumulative noise intensity. These contours can then be plotted on a map. The contours are interpreted through the use of a recommended table of land use 6-3 I I I I I I I I I I I I I i I I SOUTHHOLD84-DT.1/SOUTHOLD1.3 6/10/85 compatibility standards. This can be used to determined the presence or absence of incompatible land uses in the airport vicinity. In this case the Integrated Noise Model (INM) was used to produce the noise contour information. The INM was developed by the FAA and is available directly from that agency. 6.2.1 Noise Model Input Data As is the case with any computer model, its results are entirely dependent on the specification of the input data which in turn reflects certain assumptions about the conditions expected to exist. Input into the noise model included the volume of aircraft activity, the types of aircraft expected to use the airport, the time of day of operation (day vs. night), the physical specification of the runway location and its utilization, the aircraft flight patterns, the annual average ambient temperature, and the airport altitude. Information on aircraft source noise characteristics, flight profiles, and engine power settings is normally supplied through the data base of the noise model itself. In the case of the proposed Southold Airport, the utllmate runway length of 3,600 feet was assumed to be available. The level of expected operations is consistent with the revised activity forecasts as presented in Section 4. These overall annual activity levels are broken down to generate a daily average of activity by aircraft type according to the average runway use, time of day of operation and type of activity. These data are summarized in Appendix F, Southold INM Input Data. Two aircraft types are expected to use the Airport, single engine general aviation aircraft (SEGA) and twin engine general aviation aircraft (TEGA). Source noise characteristics for these two different aircraft types are contained in the INM and reflect the average noise signature for the entire class of aircraft represented. Three types of activity are expected to take place: local operations, itinerant operations and touch and go operations. In terms of noise model input data there is no difference between a local or an itinerant operation. However, one half of local operations by SEGA aircraft, were assumed to be touch and go's, (i.e. training flights). Ail touch and go's were 6-4 I I I I I I I I I I I I i I I SOUTfLqOLD84-DT. 1 ! SOUTHOLD1 . 4 6/10/85 assumed to operate to the northwest and occur during the day period (7 a.m.-10 p.m.). These training flights would normally occur during clear weather and during daylight or early evening hours. All remaining operations were divided equally between the two runway ends. Ten (10) percent of these operations were expected to occur during the night period, primarily before 7:00 a.m. in the morning. The remaining assumptions included an airport altitude of 50 feet above mean sea level (msl), and an annual average temperature of 59 degrees Fahrenheit. Flight tracks were assumed to be straight in and out, (i.e. aligned with the extended runway centerline). 6.2.2 Expected Noise Impacts The INM was run for each of the four (4) future forecast years. were obtained for the Ldn 65 and the Ldn 60 contours as follows: Results 1988 1993 1998 2003 Ldn 65 25.6 acres 32.0 acres 38.4 acres 51.2 acres Ldn 60 57.6 acres 70.4 acres 89.6 acres 128.0 acres As can be seen from inspection of the Ldn 65 contour, illustrated in Section 6.3, it can be expected to remain entirely on airport property and primarily on or around the runway itself for the duration of the forecast period. Generally, all land uses, particularly residential land uses, are normally compatible with cumulative noise levels below Ldn 65. Additionally, the Ldn 60 contour can be expected to remain largely on proposed airport property for the entire forecast period. Inspection of plots of the year 2003 contour indicates the presence of small areas of Ldn 60 beyond the runway clear zones. However, these are primarily over the water to the northwest of the Airport and in compatible rural uses to the southeast, assuming a northwest-southeast runway orientation. Therefore, the proposed level of service and resultant noise impacts should not create land use incompatibility in any off-airport areas. 6-5 !

Included among the reasons for eliminating sites are: parcel not of adequate size; incorrect orienta- tion for runway; obvious off-airport conflicts; and availability of land. It is hoped that this preliminary screening will be able to eliminate the majority of the candidate sites, leaving three or four of the most feasible sites for further detailed evaluation. 6.3.1 Site 1 Site 1 is Mattituck Airport, the existing public-use airport in the Town of Southold proper, which is depicted in Figure 6-2. This facility is a privately owned airport that is opened to the public on a limited basis. It consists of 18 acres and a 2,200-foot paved runway. The proposed zoning as suggested by the Town's draft Master Plan lists Mattituck Airport as R-80 (Residential Low Density A). The location of Mattituck Aviation's engine overhaul business is designated LI (Light Industrial). Mattituck Airport is surrounded on all sides by residential development, especially north, east and south as shown in Figure 6-2. In addition, there is a salt marsh which is located approximately 200 feet north of the runway and a road (Marratooka Road) further to the north. Because of these, the possibility of extending the runway to meet the needs of the proposed Southold Airport (3,600 feet) is unlikely. In addition, the overall size of the parcel is considered much too small for Southold's needs. The owner of Mattituck Airport has indicated that the facility is not for sale. Further, in view of the Town Board's resolution not to resort to condemnation to acquire Mattituck Airport (see Appendix G), it has been determined that Site 1 does not warrant any detailed evaluation in this study. For these reasons it is believed that development of Mattituck Airport as the Town-owned facility is not practical. Thus, it will not be considered further in the site selec- tion study. ! ! 6-6 I I I I I I I I I I I I I I /\ t AIRCRAFT PARKING APRON LEGEND ......

It was previously recon~nended as the Town's airport site in a study conducted by the New York State Department of Transportation (NYSDOT). The majority of Site 2 is shown as A-C (Agricultural Conservation) in the Town's draft Master Plan. An 800-foot-wide strip along the coastline is designated RR-A (Resort Residential A). It consists of six parcels of land, four of which are on the north side of Oregon Road. The other two parcels, which cover 55.3 acres are on the south side of Oregon Road and the west side of Alvahs Lane. This acreage includes a small corner lot (0.7 acres) situated on the southwest corner of Oregon Road and Alvahs Lane. The six parcels combined cover an area of 184.2 acres, which is more than adequate in terms of overall size. The most desirable runway orientation (northeast- southwest) is not possible at this site; however, a northwest-southeast runway of adequate length is certainly possible. This alignment is a close second in terms of desirability for crosswind purposes. A 3,600- foot runway can be constructed at this site. Site 2 also offers the added capability of protected clear zones, with one end of the runway facing towards Long Island Sound and the other end south of Oregon Road (included as part of the entire site). There is very little development in the area surrounding this site. All things considered, Site 2 does seem feasible and further evaluation is warranted. 6.3.3 Site 3 Site 3 is located north of Route 48, east of Depot Lane, south of Oregon Road, and west of Cox Lane. The existing Town landfill is located on Site 3; however, it is planned to be closed and relocated elsewhere in the future. This potential airport site encompasses 17 separate parcels (2 of which are owned by the Town of Southold) and covers an area of 188.6 acres, which is sufficient to support an airport of the size envisioned. A northeast-southwest runway at the desired length is not possible at Site 3. Likewise, a runway orientation of northwest- southeast cannot be constructed. The only alignment that can support a 3,600-foot runway is north-south, which is not the optimal orientation. 6-8 I I I I I I I I I I I I I I I I SOb~fHHOL D84-DT. 1 / SOUTHOLD1 . 7 6/10/85 Most of the land that makes up this site is available. The owner of two parcels that are essential to the development of Site 3 as an airport has recently stated that his land holdings are not available. In the existing Town Master Plan (which is presently being updated), a large portion of Site 3 is zoned "C-l," which is defined as "General Industrial" and "For Sale" signs are visible on one of the parcels. However, the draft of the new Master Plan suggests a change to the zoning in this area; most of Site 3 is proposed for A-C, with the east and northeast portion of Site 3 listed as LIO (Light Industrial/Office Park). There is some limited development adjacent to the landfill and across Cox Lane on Mathews Lane. However, Site 3 does not appear to be a feasible site since a necessary portion of it is not available and the Town has decided not to resort to condemnation. Thus, it will not be considered further in the evaluation of potential airport sites. 6.3.4 Site 4 Site 4 is situated south of the Long Island Railroad right-of-way and between Depot Lane and Cox Lane. The Town's draft Master Plan proposes that this site be zoned A-C. Portions of five separate parcels form this site. The total acreage amounts to 97.4 acres, which is slightly below the recommended minimum of 100 acres. Due to the size of this site, there is not one runway orientation that provides the needed runway length. In addition, a church is located directly west of the site and there is some limited development along both Depot Lane and Cox Lane. For these reasons, Site 4 is considered unfeasible and is eliminated from further evaluation. 6.3.5 Site 5 Site 5 is located north of and adjacent to Route 48, just east of Bridge Lane. This site, which consists of one large parcel, covers an area of 141.8 acres. The proposed zoning of this site is A-C, except for an 800- foot-wide strip along the Sound that is shown as Resort Residential A (RR-A). Although its orientation will not permit a northeast-southwest runway alignment, it will support the second most desired direction, northwest-southeast. This site will also permit a runway length of 6-9 I I I I I I I I I I I I I I I I SOUTHHOLD84-DT.1/SOUTHOLD1.8 6/10/85 3,600 feet with surplus on either end for clear zone protection. There is limited development in proximity to Site 5. This parcel is allegedly for sale and thus available as an airport location. Based on the favorable status of all the preliminary screening factors, Site 5 is considered a feasible site for the airport and will be evaluated further. 6.3.6 Site 6 Site 6 is situated due east of Site 5. It consists of two large parcels and two relatively small parcels, one of which is the property of Suffolk County and presently is a water retention basin. Residents near Site 6 have reported that this basin does not normally attract birds. The Town's draft Master Plan proposes that Site 6 be zoned in a similar fashion to Site 5 (A-C and RR-A). The total area of Site 6 is 138.7 acres, which is large enough to support the proposed Southold Airport. As was the case with Site 5, Site 6 is oriented in such a way as to permit only a northwest-southeast runway alignment. However, it too can accormodate a runway of sufficient length to serve the needs of Southold Town. There is little or no development in the immediate vicinity of Site 6. However, it is believed that the land comprising this site is no longer available, as was originally thought during previous phases of the study. Therefore, it is felt that Site 6 does not represent a feasible option for locating the proposed airport since the Town does not wish to condemn any land for developing the airport. Thus, Site 6 does not warrant further consideration in subsequent investigations. 6.3.7 Site 7 Site 7 is located south of the Long Island Railroad right-of-way, between Bridge Lane and Peconic Lane. Nine separate parcels are encompassed by Site 7; however it is proposed to acquire only the 1,000 feet nearest the railroad tracks of each parcel. This will result in an overall size of 100.0 acres for this site, which is adequate for a single runway airport. The proposed zoning of Site 7 is A-C. Two problems do present themselves in acquiring land for this site. First, it is unlikely that all of the owners will be willing to sell and 6-10 I I I I I I I I I I I I I I. ! I SOUTHHOLD84-DT. 1 / SOUTHOLD1 . 9 6/10/85 second, it is even more unlikely that they all will be willing to sell a portion of their property. The orientation of the runway on Site 7 will be east-west, which is not one of the most desirable alignments. Further, there is some residential development on both ends of the property, in addition to a school (Peconic School) just southeast of the site. It should also be noted that there is no ground access presently available to Site 7. All things considered, Site 7 does not appear to be very feasible and, as such, further consideration of this site is not warranted. 6.3.8 Site 8 Site 8 is also situated south of the Long Island Railroad right-of-way. It is east of Site 7 and is placed between Carroll Avenue and Bowery Lane. Like Site 7, Site 8 is composed of portions of a number of parcels. The 1,000 feet closest to the railroad of 8 separate parcels forms the boundaries of Site 8. The size of this site is estimated to be 94.7 acres. Site 8 is also proposed for the A-C zoning category. However, the problem of dealing with 8 property owners is present in this situation. Likewise, there is some residential development in the i~nediate vicinity of Site 8, in addition to Peconic School, which is just southwest of the site. This site also does not have readily available ground access. Finally, the east-west runway alignment is not the most desirable orientation. Thus, Site 8 does not present a feasible alternative in developing an airport site and is eliminated from further consideration. 6.3.9 Site 9 Site 9 is located on 3 parcels of land south of Route 48. This particular site is bordered on the east by Chapel Lane and on the west by Albertson Lane. It is directly across Route 48 from the Soundview Restaurant. The entire portion of Site 9 is shown as R-80 zoning. Site 9 covers a total area of 136.3 acres, which is of suitable size for Southold's airport. However, it will not permit the desired runway alignment -- the only feasible orientation at this site is east-west. Although the land which comprises Site 9 is available, it is largely 6-11 I ! I I I I I I I I SOUTHHOLD84-DT. 1 / SOUTHOLDI . 10 6/10/85 wetlands. This type of land typically proves to be relatively expensive in developing an airport, in addition to being environmentally unacceptable. It should also be noted that Site 9 requires extensive clearing in that a large portion of the property is covered with trees and other vegetation. A further consideration is that with the east- west orientation of Site 9's runway, operations to/from the east will be directly over the Village of Greenport, which is only one mile away from the eastern boundary of this site. All factors considered, Site 9 does not appear to be feasible for developing an airport and thus further consideration of it is not warranted. 6.3.10 Site 10 Site 10 is situated north of and adjacent to Main Road at the point where Manhasset Avenue intersects it. Island End Golf and Country Club is located next to Site 10 on its east side. This site is made up of one parcel and covers 136.6 acres. Site 10 can accommodate a 3,000-foot runway oriented in a northeast-southwest direction. The Village of Greenport abuts Site 10 to the south, which is an undesirable situation in that activity to/from the southwest will fly directly over this densely populated area. Indications are that this parcel is not available. The existing Master Plan shows that Site 10 is zoned "M," which is defined as "light multiple residence." The draft Master Plan has changed this identifier to RD (Hamlet Density Residential). This type of zoning is clearly incompatible with airport activity. In light of Site 10's inability to support a 3,600-foot runway, its proximity to Greenport, and the residential zoning of the property, it is being eliminated from further consideration as an airport. 6.3.11 Site 11 Site 11 is a narrow strip of land which encompasses two parcels and covers an area of 50.4 acres. This size is considered to be inadequate to support ~irport development. It is situated between Main Road and Narrow River Road. The proposed zoning that encompasses Site 11 is R-200 (Residential Low Density C). A 3,000-foot runway aligned in a northwest-southeast direction can be constructed on Site 11. There is 6-12 I I I I I I I I I I I I i I SOUTHHOLD84-DT . 1 / SOUTHOLD1 . i 1 6/10/85 some limited residential development due north of this site. In addition, there are some extensive wetlands south-southeast of the site. Clearly, Site 11 presents many problems and does not lend itself to the development of the Town's airport. 6.3.12 Site 12 Site 12 is Rose Field, which is an existing, privately owned airfield. It presently consists of one parcel; however, it appears that the two adjacent parcels to the east are available. With these three parcels, Site 12 covers an area of 37.6 acres, which is clearly undersized for an airport. These three parcels are all proposed for zoning in the R-80 category (Residential Low Density A). It is capable of accommodating a 2,000-foot runway oriented northwest-southeast. There is some limited residential development south of Site 12. Based upon its size, it is felt that investment in this site is not a very worthwhile venture. Thus, Site 12 will not be considered further in the airport site selection analysis. 6.3.13 Conclusions of Preliminary Screening Based upon observations made during the preliminary screening of the twelve candidate airport sites, two sites have emerged as the most feasible, warranting further evaluation. These sites are as follows: o Site 2 (Oregon Road and Alvahs Lane); and o Site 5 (Route 48 of Bridge Lane). 6.4 FINAL EVALUATION The final evaluation of the two previously identified potential airport sites will consider a number of factors in reaching a recommendation. Included among these factors are the following: o Possible airfield layout and terminal area configuration, o Surrounding land and buffer zones, o Proximity of residential development, o Location of lands in Farmland Preservation Program, o Ground access to site, o Cost of developing site, and o Environmental impacts of developing site. 6-13 I I I I I I I I SOUTHHOLD84-DT.1/SOUTHOLDl.12 6/10/85 The above evaluation factors will be considered for both sites. A rating system will be developed and applied to Site 2 and Site 5. The results of this evaluation process will be one recommended site for constructing the proposed Southold Airport. 6.4.1 Site 2 As previously identified, Site 2 is situated north of Oregon Road at the northwest corner intersecting with Alvahs Lane. The general location of Site 2 is shown in Figure 6-3, with the ultimate (2003) noise contours superimposed. It is depicted in more detail in Figure 6-4 with a suggested runway orientation. This site consists of six parcels (four north of Oregon Road and two south) totalling 184.2 acres. A. Airport Configuration The runway orientation shown in Figure 6-4 is northwest-southeast (13-31), which is the second most desirable orientation. However, the most desired alignment (04-22) is not possible at either of the final ' sites. With the alignment of Runway 13-31, it has been determined that the wind coverage of Site 2 is 86.62 percent with a 10.5-knot crosswind. The remainder of the time, the Airport would be closed to aircraft that are not designed to operate with a crosswind in excess of 10.5 knots. Runway 13-31 at Site 2 is shown with a full 3,600-foot length. Figure 6-3 depicts the terminal area on the east side of the runway, where there is ample space for such development. Since the most desired runway orientation is not possible, but runway length and terminal area development are feasible, Site 2 was awarded a 3 (Very Good). B. Surroundin~ Land Use/Buffer Zones As can be seen from Figure 6-4, Site 2's proposed property limits include the clear zone on the south end (across Oregon Road). The clear zone on the north end is over water. A 13 kV, 50-foot high overhead powerline parallels Oregon Road on its south side, which would ~equire burial. Thus, Site 2 would have total control over its clear zones and as such received a rating of 4 (Excellent) on this factor. 6-14 '1 II I I I I I $OUTHOLO-$41611 O IOOO 2000 FEET Waterville LEGEND CLEAR ZONE PROPERTY LINE RUNWAY ' Ldn --% Duck Pond Poin 0 Figure 6-3 SITE 2 SOURCE: NEW YORK STATE DEPARTMENT OF TRANSPORTATION, 1981 ESE. 1984. 6-15 SOUTHOLD, NEW YORK Airport Site Selection/ Master Plan Study I !

There are five farmhouses and seven utility buildings (i.e. barn, shed, garage), which would necessitate removal. In addition, one-half mile west of the site, there is a housing development, which includes a number of homes. These homes are located on Soundview Avenue. Based upon the proximity of residential development adjacent to Site 2 on the south and nearby to the west, it received a 1 (Fair) in this category. D. Proximity of Farmland Preservation There are no Farmland Preservation lands in reasonable proximity to Site 2. It should be noted that it is desirable to have such lands surrounding the proposed airport site, because it would serve as an excellent buffer zone to the Airport. Since the land which surrounds Site 2 is zoned for agricultural and residential use, it is possible that incompatible development may occur; however, this type of encroachment would not be possible if the surrounding land was in the Farmland Preservation Program. Therefore, Site 2 was only awarded a 2 (Good) in this area. E. Ground Access Ground access to Site 2 would be from the Route 48 north on Alvahs Lane. However, since Alvahs Lane dead ends at Oregon Road, the need to extend it so that it would serve the Airport is required. In addition, the portion of Alvahs Lane between the Route 48 and Oregon Road may require some improvements (i.e., resurfacing, widening, etc.). A portion of Oregon Road would require relocation, as shown in Figure 6-4, to permit a 15-foot clearance over the road as recommended by the FAA. Since ground access connections to Site 2 are in need of some improvement, it was given a rating of 2 (Good). F. Development Costs The base estimated cost for constructing the proposed Southold Airport in its initial phase is $2.475 million, (exclusive of land acquisition), 6-17 I I I I I I I I I I I I I I I i SOUTHHOLD84-DT. 1/SOUTHOLD1.14 6/10/85 $1.667 million of which is eligible for federal and state funding covering 97.5 percent of the cost ($1.625 million). The remaining $42,000 would be the responsibility of the To~n. Development items which are eligible for FAA and NYSDOT funding include: runway, taxiway and apron construction; airfield lighting; drainage, etc. The remainder of the $2.475 million total ($808,000) is for terminal area development, which is typically not eligible for reim- bursement from the two funding agencies. However, most, if not all, of this development would be constructed by tenants at the Airport, such as hangars, terminal/pilots lounge, and auto parking lot. (See Appendix E for a detailed presentation of the unit costs applied to the above costs). Site specific costs for developing Site 2 include: land acquisition; burial of overhead power line; relocation of Oregon Road; tree clearing along the bank of Long Island Sound; extension of Alvah's Lane; and demolishment of several residential and utility structures. Table 6-1 presents the estimated costs of developing Site 2. Of the total estimated cost of $8,057,000, $7,067,500 is eligible for federal and state funding, and $808,000 is typically associated with private interests. Thus, of this estimated cost, $181,500 would be the responsibility of the Town. Because it appears that Site 2 will be much more costly to develop than Site 5, it received a I (Fair) in this area. G. Environmental Impacts As previously discussed, environmental impacts that are typically associated with airports are not relevant in the case of the proposed Southold Airport. The two primary areas of concern are usually noise impacts and air quality. In view of the comparatively low level of projected aircraft operations and the type of activity (single.engine and light twin engine aircraft), the expected environmental impacts of the proposed airport are considered negligible. In terms of noise impact, the FAA has identified the Ldn 65 noise contour as the level where noise mitlgation measures for residential development should be considered. Noise levels below 6-18 I I I I I I I I SOUTHOLD-T.1/VTB6-1.1 6/lO/85 Table 6-1.

As discussed previously, it is therefore important to note that the Ldn 65 contour remains entirely on the proposed airport property centered around the runway. Figure 6-3 presents the Ldn 65 noise contour for the ultimate case. It is important to keep in mind that the Ldn 65 contour represents the threshold set forth by federal guidelines of noise impacted areas. (See Section 6.2 for a detailed discussion of airport noise considerations). If the proposed Southold Airport were built, federal and state air quality standards would also not be of concern. The expected impacts on air quality from an airport of the size proposed for the Town of Southold are insignificant. No other potential environmental impacts are expected at this site. As such, Site 2 was awarded a rating of 4 (Excellent) in terms of its expected environmental impacts. 6.4.2 Site 5 Site 5 is located north of Route 48 approximately 1,000 feet east of Bridge Lane. It consists of one parcel and encompasses an area of 141.8 acres. The general location of Site 5 and the ultimate Ldn 65 noise contour are shown in Figure 6-5. Site 5 is also shown in Figure 6-6 with a suggested runway configuration. A. Airport Configuration The runway orientation at Site 5 is northwest-southeast (12-30), which is the second most desirable alignment. This runway orientation provides 86.67 percent annual wind coverge with a 10.5-knot crosswind which is slightly higher than Site 2's wind coverage. The length of the runway at Site 5 is shown in Figure 6-6 as 3,600 feet and the terminal area is shown on the west side of the runway. Since Site 5 cannot accommodate the most desirable runway orientation (northeast-southwest), it received a rating of 3 in the Airport Configuration category. B. Surroundln~ Land Use/Buffer Zones As can be seen from Figure 6-6, the clear zone on the north end of the runway lies almost entirely over water, which is a very desirable situation. The other clear zone encompasses undeveloped land east of 6-20 I ! I I I I I I t I I ! t i SOUTHOLD-841611 ~~.~ ..

I SOLrl'HHOLI~4-DT.1/SOUTHOLDI.16 6/10/85 the proposed property line and Route 48. The clear zone associated with Runway 30 does not include any land south of Route 48. There are two overhead lines situated along both sides of Route 48: On the north side is a 40-foot-high telephone line, and to the south is a 50-foot-high, 69 kV power line. Based on a 20:1 approach slope to Runway 30 with a runway length of 3,600 feet, neither of these lines constitute obstructions. Since Site 5 would have authority over most of its clear zones, with the remainder being undeveloped, it was awarded a 4 in this C. Proximity of Residential Land Site 5 is reasonably well isolated from residential development. It is approximately one mile west of the development on Henry's Lane, which is the only concentrated residential development in the area. There are some scattered homes west of the site along Bridge Lane. There is one farmhouse and a number of utility structures (i.e. barn, garage, shed) on the north side of the Route 48. Three structures (two-story farmhouse, a hen house and a garage) are located on a 40,000-square foot parcel that is notched out of the proposed airport property, as shown in Figure 6-6. The owners of this parcel have publicly stated that their property is not for sale; however the need to acquire this land is not considered necessary in order to develop Site 5. As can be seen from Figure 6-6, a number of other utility-type structures are situated adjacent to the above-mentioned parcel, but are physically located on the parcel that comprises Site 5. According to the most recent survey of the property conducted on July 7, 1969, included among these structures are two large barns, a garage, and two sheds. Additionally, two shacks are situated along the western edge of the property. However, none of these structures are required to be relocated based on the runway alignment shown in Figure 6-6. There is an abandoned barn that is situated in the Runway 30 clear zone, which will need to be demolished.' Since concentrated areas of residential development are not present near Site 5 and only one unused utility structure needs to be removed, it received a 4 (Excellent) in this category. 6-23 I I I i I I I I I I / I I ! SOUTt-~IOLD84-DT. 1 / SOUTHOLD1.17 6/lO/85 D. Proximity of Farmland Preservation There are some lands which are presently in the Farmland Preservation Program in proximity to Site 5. There is presently one parcel about one- half mile east o~ Site 5 which is in the program. Three other parcels adjacent to and west of this parcel (which also abuts Site 5) have been offered for inclusion in the Farmland Preservation Program. This is an ideal situation because it would provide an excellent buffer between the only sizable residential development (Henry's Lane) and the site. There are two other parcels that are presently in the program: one south of Route 48 and west of the clear zone, the other south of the railroad tracks and north of Main Road slightly west of the extended runway centerline. This also represents an excellent situation in that the south approach is protected from future encroachment. Therefore the areas that can potentially support incompatible development are protected; in addition, the existing development has a natural buffer. As a result, Site 5 received an Excellent rating (4) in this area. E. Ground Access With Site 5's proximity to Route 48, ground access to it would not be a problem. Convenient access from all points in Town is possible. The only improvement to the site that would be required is construction of au exclusive airport access road, as shown in Figure 6-6. Since ground access is so convenient, a rating of 4 was given to Site 5. F. Development Costs The estimated base cost of developing Site 5 is the same as Site 2 ($2.475 million). Capital improvement costs not reflected in the above figure include land acquisition, power line burial, tree clearing, and access road construction. The owners of the one parcel (141.8 acres) that makes up Site 5 have placed an asking price of $2,325,000 on this land. LILCO has estimated the cost of placing the 23 kV high tension power line that traverses Site 5 underground to be $350,000 (see Appendix H). The preliminary estimate for constructing the airport access road is $57,000, assuming a 1,500-foot-long road. The total estimated cost for developing Site 5 is shown in Table 6-2.

Of this total amount, $4,310,500 is eligible for federal and state funding and $808,000 would typically be associated with private concerns. Thus, the remaining $110,500 would be the responsibility of the Town, which is $71,000 less than the Town's share associated with Site 2. In light of the significantly lower total development costs estimated for Site 5 and the resulting lower cost for the Town, Site 5 received a rating of 3 (Very Good) in this category. G. Environmental Impacts The environmental impacts that are expected from developing an airport at Site 5 are negligible. Noise and air quality impacts are essentially non-existent at an airport the size of that being considered. Since Site 5 is somewhat isolated from incompatible development, even single event noise problems should not pose a serious problem. Based on this, Site 5 was given a 4 in terms of Environmental Impacts. 6.5 RECOfR4ENDATIONS A suu~narized comparison of the two final sites is shown in Table 6-3. Based upon the detailed alternatives evaluation presented in Section 6.3 and reflected in Table 6-4, Site 5 surfaced as the most feasible site for developing the Town's airport. Table 6-4 is a summary of the evaluation results and clearly shows that Site 5 is far superior to Site 2. If for some unforeseen reason, it is not possible to develop Site 5 as the Southold Airport, then the alternative site would be Site 2. However, every attempt should be made to develop Site 5 as the airport. This process should be pursued in an expeditious manner so that any potential incompatible land uses do not materialize in the area and so that development costs do not escalate further. It is also recommended that the Town's Master Plan Update be revised to reflect Site 5 as the airport capable of being upgraded to General Utility-Stage I, so that the proper zoning is enacted. The remainder of the Airport Site Selection/Master Plan Study will focus on producing a detailed development plan for Site 5. 6-26 ! !

P~PW, Inco i RE. ~ster plan U~late Sunmmry Report: and Proposed gonin~ Re~/ulations This memorandum accompanies a ~raft of the Master Plan Update Summary Re~ort and I Proposed Zoning Regulations. With regard to the zoning provisions, this memo reflects revisions made to the draft of Articles I - XIV that was submitted to iO the Planning and Town Boards in January. . The Plan Summary reflects all of the Planning Board's latest revisions to the draft that was first prepared for the public meetings in December 1983 and February 1984. I I I I I I The Master Plan Update Stumnary is essentially the Planning Board's reco~unendations to the Town based on the work of its consultants and input from the public. This re~or~ includes the goals of the Plan, descriptions of the land use proposals, a discussion of hamlet studies and an outline of future steps. Plan maps for the four major h~mlet areas have been included within the draft, but the Plan Map for the whole Town is being shown at a scale of 1" = 1,600' and will be reduced following our April 30 joint meeting. The attached draft of the proposed revised Town Zoning Ordinance has evolved out of a process that involved a Dumber of draft proposals, draft maps, discussions with the Supervisor, Town Board members, Zoning Board of Appeals Chairman, Building Inspector and other Town officials and a series of meetings with the Planning Board to examine plan objectives, land use proposals, zoning designations, and a variety of supplementary regulations. The Proposed Zoning Regulations include sections on Definitions and Zoning Districts as well as a proposed Use Table, Lot Size and Density Tables, and Bulk Tables and various procedural and administrative sections and sections on supplementary regulations. The Planning Board has reviewed the articles within the revisions dealing with Districts, Use and Bulk Schedules and Site Plan Review and these portions of the draft directly reflect their comments. I I I-1 I ! I I I I I I I Generally, new or revised wording is underlined. For those articles (~ncluding districts) that are being revised, the changes are underlined and significant deletions are mentioned in this cover memorandum. Proposed new articles are so indicated by a note showing which, if any, sections of the current zoning ordinances have been incorporated. The new articles, however, do not contain underlining. There are a number of new and revised definitions to reflect items included in the districts, definitions that needed clarification, and some that were suggested during earlier discussions. Each article now has a "Purpose" section in order to establish the basic policy and rationale and what it is intended to accomplish. The proposed zoning map has been prepared at the larger 1" = 800' scale. Reduced versions (1"~ 1600'), the scale of the Master Plan map, accompany this draft. Revision of Districts We feel that it is important to begin the review of the new and revised regulations with an examination of the districts, particularly to determine how they relate to the Master Plan objectives. The proposed ordinance has a number of new districts designed to implement specific policies included in the Master Plan. The Agricultural Conservation (AC) and proposed Low Density Residential R-80 Districts are the basic 2-acre zones. The AC district includes mandatory clustering, whereas the Planning Board may or may not require clustering in the R-80; but the AC District is otherwise distinguished from the R-80 District only by its name and location in areas to be given priority for agricultural conservation as indicated in the Master Plan. The Low Density Residential R-120, R-200 and R-400 Districts are all new and are basically the same as the R-80 except that minimum lot areas are 3 acres (Fisher Island), 5 acres (Orient) and 10 acres (Robins Island). The R-40 District is a proposed one acre minimum residential district that is mapped in areas already predominantly developed or committed to one acre lots or less. The Hamlet Density (HD) District, which essentially replaces the "M" zone and can include various types of residential use, may be applied by the Town Board upon petition only if certain criteria are satisfied, particularly provision of utilities and proximity to hamlet centers. A major objective of the zone and a criteria to be considered in its application, is the provision of moderate cost housing. The following densities may be permitted in HD areas once mapped by Town Board. If public water service and sewage treatment were not available, the maximum density permitted would be two units per acre or 20,000 square I-2 I I I I I I i foot lots for a conventional subdivision (or by special exception permit multifamily dwellings at the same density.) T~is could vary based on property characteristics and County approval. If public water and sewage treatment were available, then areas designated as Hamlet Density could be developed at densities up to four units per acre. The Resort Residential A District is new and is basically the same as the R-80 zone except that it permits low density resort, seasonal and motel and hotel development particularly in waterfront areas consistent with the surrounding low density and agricultural development. In addition, the new Resort Residential B allows recreational marinas and a higher density of residential development. This district is intended basically for more intensively developed waterfront areas, but does not include businesses (see Marine-Business District). The RR-B District is also applied to some. sites that are now zoned "M" originally to acco~m~odate motels, hotels, seasonal housing and second homes. Year-round residential use is really a secondary purpose. Residential Office (RO) District is a proposed new district that permits profes- sional and limited business offices in areas that are a transition between the hamlet centers, outlying business areas and low density residential areas. Residential density is basically one acre. The Limited Business (LB) District is new and is intended to allow very limited business activity (antiq~le shops, wineries, bed and breakfast, professional offices) that are appropriate for limited outlying and low density areas. The primary purpose of this district is to accommodate areas currently zoned for business, but which in accordance with the Master Plan policy are not intended to expand or be intensively developed. To do so would create strip development and inappropriate uses in agricultural and low density areas. On the other hand, the Hamlet Business (HB) District is a modified version of the present B-Light Business zone and allows an array of business, office, specialty and residential uses at higher densities (if utilities are available) in the hamlet centers. General Commercial District is essentially the present B-1 District and is intended for auto-oriented uses, commercial uses that are more land-extensive and not as dependent on pedestrian traffic, and commercial uses that are not necessarily appropriate in a hamlet center. This district is applied along 1An earlier version of this district had a base density of 1 per acre and permitted 2 with water al~d 4 with water and sewer. Another earlier provision was to allow additional density in exchange for the provision of moderate cost housing. If the moderate cost housing is not mandated, the incentive would assure that at least a portion of the housing is set aside for low and moderate income families. I-3 I I I I I I i I major roads (basically Route 25) near the hamlets and near the Village of Greenport. Two special marine districts are proposed. The Marine Recreation M-Rec District is intended to encourage and accommodate recreation-oriented marine activities in selected waterfront locati6ns. Motels would only be permitted by special exception if part of a water-related development. The important priority is maintaining and expanding access to the water whether it is public or generally available as a public commercial use. This theme is also evident in the Marine Business MB District. The Marine Business (MB) category is similar except that it can accommodate more intensive marine businesses such as boatyards, commercial fishing stations and free-standing restaurants, as well as residential development which is secondary to and part of a water-related or marine-oriented use. Two industrial categories, Light Industrial Park/Office Park (LI0) and Light Industrial (LI) are included. Both of these are similar to the existing "C" Light Industrial category. The primary distinction between the two proposed districts is the intensity of use. The former requires larger parcels and low coverage and is intended for industrial areas away from the more congested hamlet areas. Many inappropriate and environmentally undesirable uses now included in the General Industrial District (C-1) are proposed to be eliminated. Further, the way that the present C-1 is written, virtually all uses except residences but including businesses are permitted in the C-1 category. Since we now have specific marine districts, marine uses are eliminated from the industrial district, thus avoiding the possibility of unwanted industrial uses along the water. Other Changes The proposed ordinance retains the existing format since it is basically sound and people are used to working with it. Summary use tables, expanded minimum lot, density and bulk tables as well as expanded parking and loading schedules are added. Special Exceptions - The draft reflects a proposed shift of responsibility for special exceptions from the Zoning Board of Appeals to the Planning Board. Special Exceptions generally involve planning decisions in that they are con- cerned with land use relationships. The ZBA can focus on appeals, variances and matters of interpretation. Air~ort - This is left in the Industrial District requiring a 100 acre minimum site and is limited to a Basic Utility - Stage II airport. Shopping Center - As a specific use this is not included, however, the uses that go into a shopping center are included in HB and B-1 Districts and there is nothing specified to prevent a shopping center. In fact when compared to a I-4 I I I I I I I I strip of individual stores, a shopping center is preferable in terms of being able to li~t curb cuts, achieve better design etc. However, unless an incentive is provided such as increased coverage or decreased parking or a disincentive is included for conventional development such as requiring very large lots, there is little reason to distinguish shopping center as a specific use, except possibly to permit joint use of parking, thus allowing more landscaped space. Marine Uses in Business Districts - Since we now have proposed a specific marine district, uses such as marinas and fishing stations are eliminated from business districts which, as a rule, will not be located on the water. Bed and Breakfast - This use i~ proposed in the Limited Business District applicable to structures existing prior to the date that zoning was in effect. They would also be permitted in those districts that allow hotels and motels. The ordinance could be further revised to apply to houses that are at least 50 years old. This would serve to limit its applicability and assist in preserving older houses. Signs - Generally, this draft suggests reducing the size of signs. While we opted to leave the basic sign provisions in each district comparable to the current sections, there is a general article on signs addressing permit requirements, design guidelines and enforcement provisions. Also, roof signs are eliminated. Protection of Natural Features and Landscapinq - Two new articles have been added to further emphasize the importance of protecting natural coastal features and enhancing the natural beauty of the land through maintenance and appropriate landscaping. Miscellaneous - While new or added uses are noted or underlined several sp6cific uses are eliminated or moved: Tourist camps are excluded from the Hamlet Business District. Non-farm labor camps are not included in this draft. Maximum Coverage Chan~es - Incorporated in the bulk tables are several changes in coverage requirements: Reductions in the maximum coverage have been recommended in the residential districts requiring a lot size of three acres or more. 20% coverage in these districts is unrealistic and might encourage the development of large buildings, particularly for permitted non- residential uses. The two proposed industrial districts permit lower coverage than is currently allowed in order to reduce impacts of industrial use and to provide for careful site planning (LIO maximum coverage ~ 20% and LI maximum coverage = 30%). I-5 II I I I I. I I I The Hamlet Business District maximum coverage has been increased to 40% to reflect more intensive uses that are appropriate in these pedestrian-oriented hamlet central business areas. For the most part, existing development is already at this density. Coverage has been increased slightly (20% to 25%) for the Hamlet Density Residential District and the Resort Residential B District to allow for greater variety in development patterns. This will still permit sufficient land for landscaping, open space and parking. Issues For Further Discussion There are several known issues that are addressed in the text, but may need further Town action to respond to the needs identified. This action may take a variety of forms in addition to revisions to the Zoning Ordinance. Roadside Farm Stands - The revised ordinance includes the basic provisions of the present ordinance with some reorganization and a limitation on products to be sold to only those grown on the premises. Accessor~ Apartments - Suggested provision for accessory apartments as a special exception use is included in all residential districts, with rigorous restric- tions. These include owner-occupancy of the structure, applicability to exist- ing structures (cut off date currently recommended to be 4/9/57). This date could be changed to one closer to the present, such as January 1, 1984, which would still prevent the construction of new two-family homes on smaller lots. An earlier date could be used to limit establishment of apartments and preserve old houses. Two-Family Houses - The current policy of allowing two-family homes as a special exception on parcels double the size of the single family minimum is retained. However, two-family homes would be permitted on smaller lots if water and/or sewer is available in some districts, e.g., the Hamlet Density Residential District, but always at twice the land area required for a single-family house in that district. Moderate Cost/Lower Cost Housing This is partially addressed in (a) provision for accessory apartments and (b) increased density (to four units) in Hamlet Density. It may be very appropriate to go beyond these zoning measures to provide housing for older and younger residents of the Town who have incomes below Southold's median income level. E.g., local housing and/or building codes should be checked to determine if modular housing can be approved since this is a potential source of moderately priced housing. Perhaps in some cases incentives could be used such as reduced dwelling unit size or higher densities than four units per acre. Trailers-Mobile Homes/Mobile Home Parks This is a complex issue. In its definition of a dwelling unit, however, the Town specifically excludes house trailer. Therefore, a house trailer cannot be put on a lot as a house. This draft does not include a specific change, except that in cases of natural emergencies or construction of a building, a trailer could be located on a site by permit of the Town Board. I-6 Tourist camp and recreation vehicle parks are allowed by special exceptions of the Town Board under Chapter 88 of the Town Code. These house trailers are allowed in certain areas for seasonal or recreation use. These provisions are referenced in the zoning ordinance. Individual house trailers are subject to special permit of the Town Board anywhere in the town, which essentially provides an opportunity to locate one in any district, except not as a dwelling unit. It may be difficult to sustain this position. This matter should be discussed further in order to assure internal consistency (i.e. a house trailer or mobile home are not dwelling units) and a sustainable position. Limitin9 Conversions of Hotel or Motel Units - A section in the supplementary regulations, limits conversion of hotel or motel units to condominium and cooperative units to location in residential districts. There is some desire to be more restrictive, i.e., limiting conversion in residential districts as well, but there is also some question about whether this could be enforced if dwelling unit livable area and density requirements were met. Wineries - The draft zoning ordinance has maintained the provision that wineries could sell wine produced from grapes grown on the premises and added the provision that grapes also could be grown within the Town. Wineries would be allowed in the agricultural conservation and Low Density R-40, R-80, R-120, R-200 and R-~00Districts, as well as the Resort Residential A, Limited .Business and General Business Districts.
