In the space provided below, briefly summarize how the stormwater runoff will be treated. Stormwater runoff will be treated by a single permanent wetpond BMP. All on-site impervious area will be directed to a wetpond BMP Offsite runoff will bypass the site through additional stormwater conveyance measures (culverts drainage channels etc.) 2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved: ❑ Approval of a Site Specific Development Plan or PUDApproval Date: ❑ Valid Building Permit Issued Date: ❑ Other: Date: b. If claiming vested rights, identify the regulation(s) the project has been designed in accordance with: ❑ Coastal SW —1995 ❑ Ph II — Post Construction 3. Stormwater runoff from this project drains to the Yadkin Pee Dee River basin. 4. Total Property Area: 134.4 acres 5. Total Coastal Wetlands Area: acres 6. Total Surface Water Area: acres 7. Total Property Area (4) — Total Coastal Wetlands Area (5) — Total Surface Water Area (6) = Total Project Area`: 134.4 acres + Total project area shall be calculated to exclude the following: the normal pool of impounded structures, the area between the banks of streams and rivers, the area below the Normal High Water (NHW) line or Mean High Water (MHW) line, and coastal wetlands landward from the NHW (or MHW) line. The resultant project area is used to calculate overall percent built upon area (BI.IA). Non -coastal wetlands landward of the NHW (or MHW) line may be included in the total project area. 8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 12.51 % 9. How many drainage areas does the project have? 1 (For high density, count 1 for each proposed engineered stormwater BMP. For low density and other projects, use 1 for the whole property area) 10. Complete the following information for each drainage area identified in Project Information item 9.

Important maintenance procedures: _ Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (commonly six weeks). _ No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. _ Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basin. _ If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the emergency drain should be minimized to the maximum extent practical. - Once a year, a dam safety expert should inspect the embankment. After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance should be kept in a known set location and must be available upon request. Inspection activities shall be performed as follows.
