WILMINGTON, N.C. 28412 '9" 0"392-5243 PHONE (910)392-5203 FAX Narrative Description: Travel from the intersection of US-117 (Shipyard Blvd) & US-421 (Carolina Beach Rd) south on US-421 approx. 6.8 miles. Turn right on Halyburton Memorial Parkway and travel approx. 1.7 miles. Turn right on River Rd. and travel approx. 0.2 miles. The property is located on the west side of River Road. Site acreage: 6.32 ac. Site acreage to be disturbed: 1.65 ac. Soils to be disturbed are mainly Ly, Kr, & Do. The runoff from the site was estimated using the rational Method, 10 year design storm and rainfall date for the area. The project is a low density site consisting of 4 existing platted lots. Stormwater will be treated by sheet flow. Erosion Control Measures: The attached plans and specifications state or show required Sediment and Erosion Control measures to be taken. A gravel construction entrance will be constructed at the entrance off River Road. Silt fence will be installed to prevent sediment from leaving the site. Sediment traps will be installed as shown on plan. Outlet protection will be installed as shown on plan. Mulching will be used on berm to immediately stabilize area. Construction Sequence: The gravel construction entrance off River Road will be installed. Secondly, the silt fence will be installed. The sediment traps will then be installed. Then clearing of the easement, excavation of the swales, construction of the berm, and installation of the utilities may begin. The berm is to be immediately seeded and stabilized with mulch and landscaping. Outlet protection is to be installed as shown on plan. Stabilize site by seeding (per specs) disturbed areas within 21 days of no construction of any phase of activity.
