IV. PROJECT INFORMATION
1. In the space provided below,briefly summarize how the stormwater runoff will be treated.
Runoff from the development will be collected into various drop or curb inlets across the site which will
discharge to a perimeter ditch by the shortest route possible.Much of the stormwater will discharge directly
into this ditch by flumes along the concrete curb.The ditch will discharge south of the project site.
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 PUD Approval 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 Cape Fear River basin.
4. Total Property Area: 64.7 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+:64.7 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(NHVV)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 (BUA). Non-coastal wetlands landward of the NHW(or MHi'9 line may
be included in the total project area.
8. Project percent of impervious area: (Total Impervious Area/ Total Project Area)X 100 =6.0 %
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. 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.
