Inspect the wet detention system for sediment accumulation, erosion, trash accumulation, vegetated cover, and general condition. b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within 2 to 5 days as designed. 2. Repair eroded areas immediately, re -seed as necessary to maintain good vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash as needed. 3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain proper functioning. 4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is reduced to 75% of the original design depth (see diagram below). Removed sediment shall be disposed of in an appropriate manner and shall not be handled in a manner that will adversely impact water quality (i.e. stockpiling near a wet detention basin or stream, etc.). The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. When the permanent pool depth reads 4.5 feet in the main pond, the sediment shall be removed. When the permanent pool depth reads 2.2_ _ 5 feet in the forebay, the sediment shall be removed.

I have the following comments: 1. Add the top elevation to the baffle or add a baffle detail to the plans. The baffle must be at least as high as the temporary pool elevation. Also, add the baffle to the plan view pond detail. 2. Add a Swale detail to the plans. Make sure that the minimum depth on the detail is deep enough to cover all the proposed swales or add a table to the Swale detail showing the required depth for each Swale. 3. It is possible for you to have the piping and ponds in the low density development, but the deed restrictions will have to be revised accordingly. All of the statements in Section I must be included in the covenants. Then, all of the statements in Section II and III should be added for the lots with curb outlet swales (listing the specific lots in the covenants) and all of the statements in Section VI should be added for the lots draining to the pond (listing the specific lots in the covenants). This is because some lot owners will be allowed to have piping and some will not. The developer may choose to not let any lot owners have piping. Whoever is drafting the permits may wish to contact me to discuss this item. S:VvVQSISTORMWATIADDINF012004i030917.aprO4 N. C.
