Howes, Secretary WATER QUALITY SECTION Regional Manager Mr. Bill Grathwol Coastal Carolina Developers 2905 Market Street Wilmington, North Carolina 28403 September 15, 1995 Subject: Submittal Requirements Brittany Woods Subdivision New Hanover County Dear Mr. Grathwol: Per our meetings in June and today concerning the April 1995 letter from this Office requesting a stormwater submittal for any portion of the Brittany Woods project that required a revised Erosion Control plan. The following items were discussed and agreed upon as they pertain to the development at Brittany Woods: 1. Portions of the project to be sold to other developers will obtain their own Sedimentation and Erosion Control plan, therefore, those portions will be required to deal with stormwater on their own. 2. The overall total built -upon area will be 30 % or less. Built -upon area includes roads, driveways, houses, sidewalks, patios, etc. It does not include wood decking and the water surface of swimming pools. A "bank account" of the total allowable built -upon area can be set up with the master plan approval, with the built -upon area from each subsequent project being subtracted from the total allowed. 3. Brittany Woods currently uses a combination of piping, grassed swales, and existing or planned detention ponds for stormwater control. The use of piping is not allowed for a low density submittal, however mitigation for the excessive use of piping and curb and gutter will be allowed. Any ponds that are used as mitigation must have a minimum depth of 3', and provide storage for the runoff. 4. A minimum of 50 % of the Class IV soils adjacent to Smith Creek will be designated and restricted as conservation areas. Impacts to the fringe wetlands along Smith Creek will be minimized. 127 Cardinal Drive Extension, Wilmington, N.C. 28405-3845 • Telephone 910-395-3900 • Fax 910-350-2004 An Equal Opportunity Affirmative Action Employer Mr. Grathwol September 15, 1995 Brittany Woods ------------------------ 5.
