IV. PROJECT INFORMATION
1. In the space provided below, bhefly summarize how the stormwater runoff will be treated.
Stormwater runoff will sheet flow across lots and collect into undereround storm drainaZe system within
roadways. Collected stormwater will be dischareed from the system into aassed swales.
2. a. If claiming vested rights, identify the supporting documents provided and the date they were approved:
F-1 Approval of a Site Specific Development Plan or PUD Approval Date:
F-1 Valid Building Permit Issued Date:
F-1 Other: Date:
b. If claiming vested rights, identify the regulation(s) the project has been designed in accordance with:
F-1 Coastal SW - 1995 F-1 Ph 11 - Post Construction
3. Stormwater runoff from this project drains to the.Cape Fear River basin.
4. Total Property Area: 55.76 —acres
5. Total Coastal Wetlands Area: 0 acres
6. Total Surface Water Area: 0 acres
7. Total Property Area (4) - Total Coastal Wetlands Area (5) - Total Surface Water Area (6) = Total Project
Area': 55.76 acres
+ Total project area shall be calculated to exclude thefollowing: the normal pool of impounded structures, the area
between the banks of streams and rivers, the area below the Normal H' h Water (NHM line or Mean High Water
(A4HYQ line, and coastal wetlands landward from the NHW (or ZIA line. The resultant project area is used to
calculate overall percent built upon area (B LLA). Non -coastal wetlands landward of the NHW (or A4HM line may
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area / Total Project Area) X 100 = 24.0 %
9. How many drainage areas does the project have?l (For high density, count I for each proposed engineered
stormwater BMP. For low density and other projects, use I for the whole property area)
10. Complete the following information for each drainage area identified in Project Information item 9. If there
are more than four drainage areas in the project, attach an additional sheet with the information for each area
provided in the same format as below.
