Stormwater runoff from this project drains to the Cape Fear River basin. 4. Total Property Area:1.8 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+:1.8 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 (MHM line, and coastal wetlands landward from the NHW (or MHI9 line. The resultant project area is used to calculate overall percent built upon area (B UA). 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 = 28.9 % 9.
