Provide all proposed Best Management Practices that will further each policy. Incomplete answers will require that the form be returned for completion. 2 DEVELOPED COAST POLICY Policy 1. Foster a pattern of development in the Town of Southold that enhances community character, preserves open space, makes efficient use of infrastructure, makes beneficial use of a coastal location, and minimizes adverse effects of development. See LWRP Section III—Policies; Page 2 for evaluation criteria. X Yes No Not Applicable The new loading ramp support facilities for vehicles and passengers and bulkhead replacement sheeting make continued appropriate use of an existing waterfront site and complies with environmental design factors published by the NYS DEC Tidal Wetlands Regulations, Southold Local Law No. 6, 2004 and the Southold LWRP. The new bulkhead will basically be driven immediately behind the existing bulkhead. Piles will remain about 4' above the finished grade of the bulkhead. There will be no impairment of water flow or navigation. Policy 2. Protect and preserve historic and archaeological resources of the Town of Southold. See LWRP Section III—Policies Page 3 through 6 for evaluation criteria. Yes No X Not Applicable Policy 3. Enhance visual quality and protect scenic resources throughout the Town of Southold. See LWRP Section III — Policies Pages 6 through 7 for evaluation criteria Yes No X Not Applicable This site is restricted to public access. The terminal site and harbor facilities are visible from the water only when directly south of the line of the harbor. The only portion of the proposed work visible to any extent is the harbor from the south and, at a distance, the changes in appearance will hardly be noticeable. The only land side visual access affected by this project is at the road and the industrial nature of the site and ferry landing facilities will be unchanged by the repair work. 3 NATURAL COAST POLICIES Policy 4. Minimize loss of life, structures, and natural resources from flooding and erosion. See LWRP Section III—Policies Pages 8 through 16 for evaluation criteria. Yes No X Not Applicable The proposed bulkhead restoration will take place in the harbor and is acknowledged to be in a flood-prone area; there is little damaging wave exposure at this site and existing sloped stone wave attenuation sections dampen waves which enter the basin through the channel entrance. Nonetheless, the bulkhead has been designed to accommodate complete submersion and resist hydrostatic uplift pressures due to flooding. The project site, in fact all of the ferry terminal facilities,are landward of the Coastal Erosion limit line. Policy 5. Protect and improve water quality and supply in the Town of Southold. See LWRP Section III—Policies Pages 16 through 21 for evaluation criteria. Yes No X I Not Applicable This project will not have any affect on suitability of or availability of drinking water. Policy 6. Protect and restore the quality and function of the Town of Southold ecosystems including Significant Coastal Fish and Wildlife Habitats and wetlands. See LWRP Section III—Policies; Pages 22 through 32 for evaluation criteria. X Yes No Not Applicable This project is consistent with this policy because it proposes minimal work in an area of no tidal wetlands or submerged aquatic vegetation. With regard to the use of CCA pressure- treated Southern Yellow Pine in the course of construction,the NYS DEC prepared a study showing that the proposed pressure-treated Southern Pine timber products construction materials are suitable for this type of project in this location.The design parameters shown on the drawings provides an optimum balance between acceptable design and access standards without adverse environmental impact. Because of vessel loading potential, the dolphin fender piles will be Greenheart. Policy 7. Protect and improve air quality in the Town of Southold. See LWRP Section III—Policies Pages 32 through 34 for evaluation criteria. Yes No X I Not Applicable There are no air quality issues related to this project. No emissions will be generated by the ferry landing facility. 4 Policy 8. Minimize environmental degradation in Town of Southold from solid waste and hazardous substances and wastes. See LWRP Section III — Policies; Pages 34 through 38 for evaluation criteria. Yes No X Not Applicable Any non-soil salvaged waste from the excavation and the pressure-treated wood trimmings from the fender repairs and any steel bulkhead sheeting cut-offs from the demolition will be collected and disposed of in accordance with current regulations by a licensed hauling contractor already providing such services to the PIADC facility and utilizing best management practices so as to minimize any harmful affect. PUBLIC COAST POLICIES Policy 9. Provide for public access to, and recreational use of, coastal waters,public lands, and public resources of the Town of Southold. See LWRP Section III — Policies; Pages 38 through 46 for evaluation criteria. Yes No _X Not Applicable This project is being built on Federal land in a manmade Ferry Terminal basin. The public trust lands and waters typically constitutes the area between the mean high water line and mean low water line and the resources are from the high tide line out, and there is none on this site. Environmental resources elsewhere onsite are being protected by the design standards dictated by the Federal Government. There is no public use of the waterfront in this area and the repair of the ferry landing facilities mostly landward of the apparent high water line are not likely to influence or change this fact. This Federal facility is exempted from the NYS Coastal Management Program and the PIADC is specifically listed as such in the CAM Act Appendix D. WORKING COAST POLICIES Policy 10. Protect Southold's water-dependent uses and promote siting of new water-dependent uses in suitable locations. See LWRP Section III — Policies; Pages 47 through 56 for evaluation criteria. X Yes No Not Applicable This project is to repair the ferry landing bulkhead at the Orient Point ferry terminal, a high priority, water-dependent use, Federal installation This usage is defined as water- dependent in the LWRP because the operation provides essential transportation access to and from Plum Island. Ferry access is the only form of transportation to and from the island. 5 Policy 11. Promote sustainable use of living marine resources in Long Island Sound the Peconic Estuary and Town waters. See LWRP Section III — Policies; Pages 57 through 62,for evaluation criteria. Yes No X Not Applicable This facility is not used for commercial fishing or shellfish industries or enterprises. Policy 12. Protect agricultural lands in the Town of Southold. See LWRP Section III—Policies; Pages 62 through 65 for evaluation criteria. Yes No X Not Applicable This facility is not used for or in support of any agricultural or aquaculture industries or enterprises. Policy 13.Promote appropriate use and development of energy and mineral sources. See LWRP Section III—Policies; pages 65 through 68 for evaluation criteria. Yes No X Not Applicable This facility is not used for or in support of any energy or mineral mining or processing operations. PREPARED BY_Keith B.Neilson,P.E. Docko,Inc.

The waterfront is approximately 1,250 feet of wharf and terminal ferry landing facilities, built originally by the US Army in the early 1900's and later transferred to the Department of Agriculture. Plum Island, and the PIADC, is now owned and operated by the United States Government's Department of Homeland Security. Plum Island is a secured Federal facility, on land owned entirely and solely by the Federal Government. There are no public trust issues associated with this site. Public access is prohibited and actively enforced by armed guards. The PIADC Orient Point Harbor facilities are situated upon terrain which is generally flat in the area of the harbor infrastructure with gently sloped surrounding terrain. The terrain mostly paved over sandy, gravel earthen material. Operational surfaces are built up landward of the bulkhead wharf facilities to support ferry operations of a semi-industrial transportation hub nature. The top elevation of the ground surface behind the bulkhead in the project area is approximately 10 feet and is at or above the Coastal Erosion line as typically applied to Town of Southold coastal sites. The Coastal Erosion limit line cuts across the entrance channel 300 feet east of the work area and all aspects of this project are landward of it. The developed shoreline is industrial in nature, paved and substantially protected. This basin is "manmade"; there are no public trust issues at this site. There is no tidal wetland vegetation on the bulkheaded work site and no submerged aquatic vegetation in the adjacent near shore waters. This project is the restoration of existing facilities, the complete north section of the steel pile sheet bulkhead at both of the ramp landing facilities, the wood pile fenders, fixed wood pier repairs and service utilities. The scope of work for this project will be undertaken in one construction contract. One element of the work is to install a new steel sheet pile bulkhead immediately landward of the existing bulkhead, along the basin wall immediately adjacent to the Plum Island ferry landing ramp in the north side of the harbor. This bulkhead suffers from extensive corrosion and impending material failure. The tie-back system is also corroded and deteriorated, and the sheets have been damaged by the wear and tear of ferry operations loss of section and the relentless exposure to marine waters. The new bulkhead will be set landward of the existing steel sheet pile system which will remain during construction to act as toe stabilization of the new bulkhead. The sheet piling will be backfilled with crushed stone so as to provide lateral stability to protect the existing sheets from further surface erosion and oxidation. The worn-out section of the existing bulkhead, will be extracted. All of this bulkhead and ramp infrastructure work will be landward of the Spring High Tide Line/Apparent High Water line only the pier an tie-off/fender system work will be in the water. 1 The other related element of this project is to re-install the heavy duty vehicle ramps to the east and west of the wood pier, relocating the west ramp 5 feet to the west at its current elevation and raising the east ramp, in place, by 18 inches. This ramp facility will be pile mounted to eliminate settlement due to heavy, dynamic loads and will protrude to the same encroachment limits as now exist. This supplemental narrative has been prepared in accordance with the requirements of State and Federal permit agencies and the Town of Southold's Ordinance No. 6, 2004, and the Local Waterfront Revitalization Program related to docks and shorefront improvements. This project site is landward of the Coastal Erosion limit line. This project is a federal installation and exempted from provisions of the NYS Coastal Management Act and is so listed in Appendix D. Pertinent factors for consideration under Section 661 of the NYS Department of Environmental Conservation regulations for Tidal Wetlands and adjacent areas are addressed herein but the emphasis is that neither tidal wetlands nor SAV exist in or immediately adjacent to the work site and no impact to those resources, if they exist nearby, will result from the project. The proposed work falls within the scope of the US Army Corps of Engineers Nationwide Permit No. 3. PROJECT PURPOSE This existing bulkhead system was installed approximately 40 years ago. The system has corroded and deteriorated under climatic conditions and routine wear and tear and must be replaced in order to provide the PIADC facility with viable, structurally sound vehicle and freight transfer and supply to/from Plum Island for essential transportation of materials, equipment and personnel on a daily, all-weather basis. ADJACENT PROPERTY OWNERS The Federal Government owns Plum Island and this site in its entirety. The nearest adjacent property is the Cross Sound Ferry Terminal at Orient to the east and the restaurant and marina. To the east, the tip of Orient Point almost a mile away, is also owned by the Federal Government and utilized for the point of access for primary electrical and water service to Plum Island. PHOTOGRAPHS Photographs of the project site, as released by the Department of Homeland Security, are attached herewith. PROJECT ALTERNATIVES There are only three real options to pursue at this time to maintain the operational efficiency and capacity of the transportation system. • Do nothing • Repair and restore the existing facilities, as is, or • Replace and modify the facilities in some way During the underwater diving visual inspection ten years ago, small isolated holes were observed in the steel sheeting near the point of embedment indication substantial loss of section and 2 structural stability. The exposed sheet at these holes were razor sharp, indicative of the loss of steel. The existing facilities have been burdened with vehicle loads beyond original expectations when highway loading went from 60,000 pound to 80,000 pound loads in the 1990. The "do nothing" option is not considered viable or appropriate because the existing bulkhead is in such condition that failure to repair and protect the structure will necessitate the discontinuance of its use in the near future. Collapse or failure of the bulkhead would close the ferry slips. The second'option is very limited. The scour damage to the bulkhead runs almost the full length of the steel sheeting. There is no good, cost effective method of repairing 40-year-old corroded steel in an underwater marine exposure without driving new steel sheeting or casting new concrete structures. With that in mind, over sheeting becomes the most economically feasible option. The major draw back of this approach is the constriction of the basin which is already critically small. The third option is complete replacement of the facilities. This would be the most costly and would require the ferry operations to be out of only one slip for the longest period of time and for both reasons, represents a hardship. Pursuing this course of action would, however, yield a more or less maintenance free operation for decades and not constrict future operations. The ramp structure will be mounted so as to avoid potentially damaging pavement surcharge loads to the bulkhead backfill. The new bulkhead would have a tieback anchor system and can be and will be located behind the existing bulkhead to avoid the progressive constriction of the basin. Minor repairs to the wood pier are proposed including new tie-off piles into the pier structures as well as the critical bresting dolphins. SEQUENCE OF WORK As mentioned in the introductory paragraph, this project is to restore the bulkhead and ferry ramp landings at the Orient terminal of the Plum Island Animal Disease Center in accordance with guidelines set forth by the State of New York DEC and the Town of Southold ordinance No. 6, 2004. With regard to the scope of work for this project, the sequence of work will be as follows: ➢ The work area will be prepared, including pavement removal and excavation of existing gravely, sandy backfill to unload the existing bulkhead and clear the way for new repair and restoration construction with minimal erosion or sloughing potential. ➢ Obstructions and utilities will be removed as necessary to make way for the layout of the new work. New utility services will be re-installed. It is envisioned that the ferry landing ramp sheet pile bulkhead walls will be installed utilizing the following general sequence and methodology. ➢ The marine contractor will arrive by land and by barge with deck-mounted crane, push or tugboats and at least one work boat. All equipment will be on the barge or be trucked onto the site. ➢ The existing ramps supports and fenders 1 dolphins counterweight towers as necessary, will be removed to make way for the installation of the new bulkhead. ➢ The gravely backfill will be excavated down to approximately the mean low-water line to minimize backfill loads on the existing bulkhead. ➢ The concrete ramp wells will be demolished and removed but leaving the scour wall in place. ➢ The new sheeting will be installed while the ramp is out of position. These sheet piles will be driven at the general locations shown in the application drawings immediately behind the 3 existing wall and around the ramp wells. Crushed stone and/or gravel backfill will be placed between the new and existing bulkhead sheet at the scour wall. ➢ The hinged ramp will be reinstalled to match pre-existing conditions but set on steel piles. ➢ Bulkhead tie-back anchor rods showing any wear or distress will be cut and re-installed to the new anchor system driven behind the new bulkhead. ➢ Wood fender piles and the wale/cap system on the top of the existing bulkhead will be removed to complete this phase of the installation. ➢ New or relocated fender piles will be driven in front of the new bulkhead. ➢ Pier and slip/guide fender repairs will be accomplished, driving new steel "king" piles in the pier and designated dolphins. REQUIREMENTS OF SECTION 97-25 OF THE WETLANDS LAW The permittee acknowledges that the validity of this permit is subject to the approval of other governmental or municipal authorities. The permittee does, by the acceptance of this permit, assume all responsibility for operations undertaken pursuant to this permit, and shall take all precautions for the prevention of injuries to persons and property resulting from such operations. The permittee gives consent to the State or Town and its officers, employees and agents to enter upon the premises where such operations are being conducted to make such inspections to determine whether said operations are being conducted in conformity with the permit; such access and inspections are governed by the operating rules and regulations of the U.S. Department of Homeland Security, PIADC. The permittee will notify the Trustees in writing one week prior to initiation of any and all operations, and likewise the NYS DEC on forms provided in the permit. The permittee will notify the Trustees and State DEC in writing upon completion of operations such that the site can be inspected for issuance for a certificate of compliance. In response to Town of Southold Local Law Number 6, the following additional information is offered. 1. Permits for the work are being applied for through the Town, USAGE, The NYS DOS and NYS DEC. This project is exempted from a coastal zone consistency determination by the NYS DOS and this has been confirmed with the DOS. This project is covered by the US ACOE Nationwide Permit No. 3. 2. Any facilities constructed of wood, will be of sturdy, durable and stable materials; in all likelihood, CCA pressure-treated Southern Yellow Pine or Greenheart piles, with one or multiple 1" minimum diameter galvanized bolts per connection and wrapped with galvanized cables,if required for clustered piles. 3. It is respectfully requested that the use of CCA pressure-treated piles (as an option to Greenheart piles) and timbers be approved for this project if Greenheart is unavailable or they are determined to be the most advantageous option to PIADC. 4. The 15-foot property line clearances specified in this paragraph are complied with. 5. Upon receipt of the permit (if required) for this project, appropriate permit numbers and/or certificates will be affixed to the most seaward face of the center dolphin for identification from the water. 6. The ramps, decking and railing will be reinstalled. Area lights on the ramp facility will be moved to be clear of the tie-back anchors as will the electrical service panel and all utilities. 4 7. There is no need to provide adequate room for a five-foot passageway on the upland. Terminal facilities are Federally owned and operated, subject to the security provisions of Homeland Security installations. Public access is prohibited. US Army Corns of Engineers— This project is covered under Nationwide Permit #3 of the US Army Corps of Engineers for repair and restoration of the bulkhead. It is anticipated that PZ 35 steel sheets will be used. The bulkhead face to face separation would be 18 inches. If US PZ 35 steel sheets are not available, Arbed AZ 26 steel sheets will be used as a last resort; even set hard against the existing steel wale, these sheets would create a 24 inch face to face separation. The new bulkhead cannot be driven outside the existing bulkhead because of the already constricted vessel maneuvering space, which cannot be reduced further. Because of the 22-foot grade to bottom elevation difference, the existing wall cannot be removed to allow "in place"replacement. NYS DEC Tidal Wetlands Regulations—Sections 661.5 and 661.9 This project represents the replacement of existing, long-standing bulkhead and new ferry landing facilities for Plum Island with no adverse environmental impacts and no further encroachment into tidal waters. This facility was most recently re-built in the early-1990's and has been routinely maintained since that time. There are no tidal wetlands or dune vegetation within several hundred feet of the site and no SAV in the waters adjacent to the wall. A ferry landing on the waterfront is considered to be generally compatible use in an adjacent area (AA) with a permit being required under Section 661.5 (b) (1), 15 and 24. This project, however, is repair and restoration of existing facilities with no new encroachment. Under Section 661.9, the standards for issuance of permits of NYS DEC regulations, the following are considered to be pertinent considerations. The policies are created to preserve and protect tidal wetlands and prevent their despoliation and destruction and that regulated activities will not have an undo adverse impact on the present or potential value of the nearby tidal wetlands. This new ramp and bulkhead restoration project for the ferry terminal is compatible with public health and welfare policies of the State specifically referenced under Section 661.6. ➢ The project complies with development restrictions contained in Section 661.6 as this is repair and restoration of an existing, long-standing facility that has previously undergone review by the Department in rendering previous permits. Furthermore, the project supports the continued operation of a long-standing, high-priority, secured Federal installation and the waterfront ferry facility structure is compatible with the use of the site, zoning and the long- standing use of the site. ➢ This project will not have an undo or adverse impact on the present or potential habitat value of nearby tidal wetlands vegetation. There are no tidal wetlands in the Plum Island terminal harbor; all of the terminal shoreline is developed shorefront. Construction materials will be in accordance with the NYS DEC standards and Town of Southold regulations and laws as previously addressed. Town of Southold—LWRP,NYS DOS Coastal Consistency These application documents include a copy of the Town of Southold Local Waterfront Revitalization Program (LY-IRP) work sheet addressing what would customarily be pertinent sections of the plan. The NYS DOS has suggested that since the Coastal Management Act does not apply to 5 this project, neither does the LWRP. Nonetheless, the following policies from the Local Waterfront Revitalization Program would normally be appropriate and have been identified as pertinent to this application and the reason for consistency associated with this project is outlined in each respective case. Policy 2 —Water Dependent Uses — This project is to retain a fully functional water dependent use of a ferry terminal facility for an essential transportation to and from Plum Island. Policy 5 — Use of Existing Developed Shorefront This project will be primarily to repair and restore existing shore / ferry interface structures, clear of sensitive habitat or tidal wetlands and make them safe and reliably usable in all weather conditions, excluding coastal storms. Policy 7 — Significant Fish & Wildlife Habitat Protection of significant fish and wildlife habitat has been considered in the development of this project layout. The waters around Orient Point are classified as essential fish habitat, however, the actual terminal is an industrial facility in a man- made harbor, not representative of desirable natural habitat. In any case, these facilities will be restored in kind and substantially "in place". Policy 8 — Protection & Preservation of Habitat Protection and preservation of habitat has also been considered in this project and the terminal facility is being kept to its minimal configuration consistent with standards of the industry and restrictions set forth in the Wetlands Law, No. 6, 2004 set forth by the Town of Southold. The ferries will operate at the same location and within the same footprint as the current operation. There are no significant changes to the dimension or configuration of the bulkhead and ramp facilities but the bulkhead face will be recessed 18 inches. Policy 11 —Minimize Damage to Natural Resources The bulkhead repair and restoration project has been laid out in the same footprint so as to be consistent with and so as to minimize impact to natural resources as identified in Policy 7 above. There is no sensitive fringe wetlands growth and there is no submerged aquatic vegetation in the sub-tidal zone where the work is to take place. Policy 14—No Measurable Increase in Flooding_ This project consists of repairs of ferry terminal facilities that will in no way adversely affect water flow and circulation in the harbors flooding potential of the area. Flood levels all around Orient Point and Plum Island are dictated by water levels in Gardiners Bay, Long Island Sound and Block Island Sound and these structures will have no adverse influence on those flood levels. Policy 15 — No Dredging= Dredging is not required in this project, however, backfill material trapped between the two bulkhead, which falls into the basin, during the extraction of the existing bulkhead, will be dug out and incorporated in to the project scope of work. The waters in this small man-made harbor is appreciably deeper offshore and the ferry arrival and departure maneuvering tends to keep the finer-grained sediments from accreting at the ramp landing sites of the proposed work. Policy 19 —Impact on Public Access — There is no public access to or usage of lands at this site; there is no intertidal zone. Thus, public access to the State's waters is not possible at Plum Island because of the design of the ferry terminal facilities and site security requirements. Plum Island is a secured Federal research facility where recreation or unsecured public access is not allowed; access is, in fact, prohibited in the interest of national security and the health and welfare of the public. Policy 20 —Public Trust Compatibility with Existing Adjoining Properties and Land Uses Public Trust compatibility to existing adjoining properties and land uses has also been considered but is not relevant in this project. 6 I Policy 21 — Water Dependent Recreation — This project is consistent with water-dependent uses opportunities policies set forth in this section. The facilities will continue to be used for essential transportation for Federal installation at the ferry terminal. Policy 24—Scenic Resources Impairment or Loss - This policy is intended to prevent impairment or loss of scenic resources. The construction of the ramp facilities will not represent any new encroachment or structure which would create a loss of scenic resources. The terminals are industrial, working waterfront sites. The elevated northerly bulkhead section on will be only 18 inches to a couple of feet higher than the existing facility and will not even be noticeable from the waters off-shore which are a minimum of a quarter-mile distant. Policy 25 —Enhance Overall Scenic Quality - The new ramp facilities will be consistent with the historic scenic quality of the area and prevent loss of scenic resources as described in Policy 24 above. The refurbished facilities will hardly be noticeable in context with the other existing facilities which dominate the shore of the harbors and again, these are industrial nature working waterfront sites and the repair work is confined to the developed shorefront. Policy 44 — Preserve and Protect Tidal Wetlands — There is no tidal wetlands on this project site. While the terminal facilities abut dune and tidal wetlands vegetation areas, this project will have no adverse impact on wetlands vegetation which exists elsewhere in and beyond the harbor facilities. SUMMARY This project is to restore a longstanding ferry terminal bulkhead and to the ferry ramps and associated intermodal transportation facilities for the US Department of Homeland Security serving Plum Island. A copy of all US Army Corps of Engineers, NYS DEC and Town of Southold applications are attached as substantiation for this project. The Corps has indicated that ramp repair and restoration work may proceed under Nationwide Permit No. 3. This project complies with applicable standards of the New York State Coastal Management Act (although not required to do so), Town of Southold Local Ordinance No. 6, 2004 and Local Waterfront Revitalization Program and is a presumptive compatible use under NYS DEC Regulations Part 661; its approval by all agencies is respectfully requested.
