Page 10 of 10 PCN Form - Additional Information Upgrade Dock and Boat Ramp Section A.1.6 Nationwide Permit 54 covers the construction of the detailed granite sill and the establishment of coastal vegetation landward of the sill. Nationwide Permit 36 covers the construction of the launch ramp at the site. Minor deviations to the size of the ramp will require a waiver. Section B.3 Item 3b. No 404 or Coastal Wetlands exist within the proposed project footprint. Item 3c. No streams- Total project area occurs over approximately 134 linear feet of tidal shoreline. Item 3d. The shoreline area is utilized to instruct and practice the deployment and recovery of ribbon bridge sections in an actual marine environment. The existing shoreline is in a badly deteriorated condition caused by shoreline erosion. The purpose of the project is to restore the shoreline area and launch and recovery area to an adequate condition to allow training exercises to continue at the locations and to stabilize the site in a manner to prevent future deterioration. Item 3e. This project includes the repair of the existing launch and recovery area utilized for Improved Ribbon Bridge deployment and recovery at the shoreline of French Creek in the Weil Point area of MCB Camp Lejeune. The project includes the installation of a 30' W x 30' L articulated -concrete mat revetment above and below the normal water level to be utilized for bridge deployment and recovery. A new concrete slab will be constructed on the adjacent upland areas in order to expand the existing equipment staging area. The proposed mat width of 30 feet exceeds the maximum allowable width of 20 feet authorized under Nationwide Permit No. 36. The 30 -foot width is needed in order to provide adequate area for bridge and equipment staging and deployment in an instructional environment and is submitted as a request for a waiver to the permit conditions. The articulated concrete mat will extend between 15.5 feet and 28.3 feet below the normal high water level. Regional Conditions 4.1.1 of the Nationwide Permit No. 36 limits the offshore limit to 20 feet. A waiver to this 20 -foot limit is requested to allow for an adequate stabilized area below the normal water level to practice bridge deployment and recovery. The project also includes the construction of a detached granite rip -rap sill offshore of launch and recovery mat in order to provide a method of protection of the existing shoreline from further erosion. The area behind (landward) of the sill will be filled and vegetated with coastal vegetation. The placement of the articulated concrete mat, concrete slab, and detached sill will occur from upland areas. Equipment to be utilized to complete the project include an excavator, crane and dump trucks. Access to the site will occur along the existing graveled Weil Point Road. Section C - Proposed Impacts Inventory Item 4g. Open water impacts are as follows: • Proposed Articulated Concrete Mat - 482 SF (0.011 AC) below normal high water elevation. • Proposed rip rap sill, backfill and vegetation area below the normal high water elevation is 1,725 SF, 0.0396 AC. Total proposed impacts below normal high water level is 2,207 SF, 0.506 AC. Section D - Impact Justification and Mitigation Item 1.a The proposed articulated concrete mat is would be placed in the footprint of the sandy shoreline historically utilized for ribbon bridge deployment and recovery training. No new shoreline areas are proposed to be impacted. The dimensions of the mat area were minimized to avoid excess impacts to shoreline and other areas below the normal high water level. The articulated mat not only is less disturbance to install, it also will settle instead of scouring and cracking, like a traditional poured slab. The extents of the proposed sill were minimized to the extent necessary to protect the section of shoreline and maintain the stability of the structure. Coastal wetlands and protected shallow water habitat will be established landward of the detached sill in areas where none presently exists. Item 2. Construction will occur from upland areas only. If should not bi necessary to operate equipmept within the vlrater. A prefabricated concrete articulated mat was seirted to stabilise the development area to avoid The need to utilize cast -in-place concretq. This eliminates the need to construct a coffer dam or complete dewatering to facilitate construction. l Section F —Supplementary Information Item 5d.

Nationwide Permit 36 covers the construction of the launch ramp at the site. Minor deviations to the size of the ramp will require a waiver. Section B.3 Item 3b. No 404 or Coastal Wetlands exist within the proposed project footprint. Item 3c. No streams- Total project area occurs over approximately 134 linear feet of tidal shoreline. Item 3d. The shoreline area is utilized to instruct and practice the deployment and recovery of ribbon bridge sections in an actual marine environment. The existing shoreline is in a badly deteriorated condition caused by shoreline erosion. The purpose of the project is to restore the shoreline area and launch and recovery area to an adequate condition to allow training exercises to continue at the locations and to stabilize the site in a manner to prevent future deterioration. Item 3e. This project includes the repair of the existing launch and recovery area utilized for Improved Ribbon Bridge deployment and recovery at the shoreline of French Creek in the Weil Point area of MCB Camp Lejeune. The project includes the installation of a 30' W x 30' L articulated -concrete mat revetment above and below the normal water level to be utilized for bridge deployment and recovery. A new concrete slab will be constructed on the adjacent upland areas in order to expand the existing equipment staging area. The proposed mat width of 30 feet exceeds the maximum allowable width of 20 feet authorized under Nationwide Permit No. 36. The 30 -foot width is needed in order to provide adequate area for bridge and equipment staging and deployment in an instructional environment and is submitted as a request for a waiver to the permit conditions. The articulated concrete mat will extend between 15.5 feet and 28.3 feet below the normal high water level. Regional Conditions 4.1.1 of the Nationwide Permit No. 36 limits the offshore limit to 20 feet. A waiver to this 20 -foot limit is requested to allow for an adequate stabilized area below the normal water level to practice bridge deployment and recovery. The project also includes the construction of a detached granite rip -rap sill offshore of launch and recovery mat in order to provide a method of protection of the existing shoreline from further erosion. The area behind (landward) of the sill will be filled and vegetated with coastal vegetation. The placement of the articulated concrete mat, concrete slab, and detached sill will occur from upland areas. Equipment to be utilized to complete the project include an excavator, crane and dump trucks. Access to the site will occur along the existing graveled Weil Point Road. Section C - Proposed Impacts Inventory Item 4g. Open water impacts are as follows: Proposed Articulated Concrete Mat - 482 SF (0.011 AC) below normal high water elevation. • Proposed rip rap sill, backfill and vegetation area below the normal high water elevation is 1,725 SF, 0.0396 AC. Total proposed impacts below normal high water level is 2,207 SF, 0.0506 AC. Section D - Impact Justification and Mitigation Item 1.a The proposed articulated concrete mat is would be placed in the footprint of the sandy shoreline historically utilized for ribbon bridge deployment and recovery training. No new shoreline areas are proposed to be impacted. The dimensions of the mat area were minimized to avoid excess impacts to shoreline and other areas below the normal high water level. The articulated mat not only is less disturbance to install, it also will settle instead of scouring and cracking, like a traditional poured slab. The extents of the proposed sill were minimized to the extent necessary to protect the section of shoreline and maintain the stability of the structure. Coastal wetlands and protected shallow water habitat will be established landward of the detached sill in areas where none presently exists. Item 2. Construction will occur from upland areas only. It should not be necessary to operate equipment within the water. A prefabricated concrete articulated mat was selected to stabilize the development area to avoid the need to utilize cast -in-place concrete. This eliminates the need to construct a coffer dam or complete dewatering to facilitate construction. Section F — Supplementary Information Item Sd. The MCB Camp Lejeune Integrated Natural Resources Management Plan requires the base to compile information and evaluate data regarding all natural resources on base, including information on protected species. This plan is updated every five years and is reviewed by NOAA, FWS, and NCDMF. This project does occur in the vicinity of red cockaded woodpecker habitat but the footprint is limited to previously disturbed, very nearshore and shoreline areas and will not impact longleaf pine savannah habitat. This shallow area (<2 feet) is also not preferred habitat for the Atlantic sturgeon and the project does not include any in -water noise producing activities. 4..y All 4 ;,,' ,yPS '•.. �,Z.. 2 C, � . f �s .' f X25 �" ' _ �` j,.

National Marine Fisheries Service has established general guidelines for pier and dock work that involve noise. The Contractor is to post observers along the creek near the job site while dredging, etc. in the water. If a marine mammal (a bottlenose dolphin or a manatee) is observed within 100 meters of the project, the activity should be stopped unfit the animal has left the area If there is no loud noise anticipated in the water (i.e. no pile driving), this 100 meter rule is not necessary. Contact Threatened and Endangered Species Secfion, ECON at (910)451-7228/7229 for further questions. 2. The Contractor shall manage and control construction activities to minimize interference with and damage to fish and wildlife. Do not disturb fish and wildlife.
