The current development plan is for a cluster type residential subdivision consisting of 315 cottages and an amenity site. Cape Cottages, LP proposes to develop 315 cottages, known as Cape Cottages on approximately 30.4 acres of the existing tract. The site is bounded by the Summer Bay Villas Development to the north, undeveloped tracts to the east & west, and wetlands to the south. The existing conditions of the site are mostly wooded with some slight clearing for a dirt road. The site contains wetlands as determined by the United States Army Corps of Engineers (SAW-2006-00669). The existing topography contains a range of moderate to steep slopes ranging from 5-15%. The predominant soil types on - site belong to hydrologic soil groups A and B. The site drains to Jackeys Creek which is a tributary of the Brunswick River in the Cape Fear River Basin. Jockeys creek is classified as C;Sw with an index number of 18-77- 3. The Cape Cottages site work will consist of the clearing and grubbing of an existing wooded area, grading of the existing contours, and the construction of utilities, roadway, sidewalks, driveways, an amenity site and 315 cottages. Stormwater runoff will be treated by two proposed wet detention pond stormwater control measures (SCMs). The SCMs will discharge to the existing wetlands adjacent to the south and south east portions of site. Each of the SCMs will be constructed to meet the minimum design criteria for wet detention ponds as set forth in the NCDEMLR/DEQ Stormwater Design Manual. Perimeter erosion control measures will be installed prior to the mass clearing / grubbing and grading of the site. These measures include silt fence with associated outlets and a construction entrance. Once construction begins, internal measures will be installed and maintained until the site is fully and permanently stabilized. These include two skimmer sediment basins, inlet protection of newly installed catch basins, seven to fourteen day, temporary stabilization of slopes, and energy dissipaters at outlets and areas of concentrated flows. The anticipated construction sequence is as follows: 1. Install perimeter silt fence and construction entrance; 2. Clearing of site; 3. Install remaining erosion control measures (skimmer sediment basins, temporary diversions, etc.); 4. Site rough grading; 5. Install drainage conveyances (pipe networks and swales); 6. Install water and sewer systems; 7. Install roadways; 8. Install buildings; 9. Install Sidewalk; 10. Final grading of site; 11. Permanent stabilization of site. Remove all temporary erosion control measures. Restore wet detention ponds to design specifications upon completion of project.
