In the space provided below, briefly summarize how the stormwater runoff will be treated. Construction of two additional warehouses and parking on the existing site. Project includes new storm drainage system and wet pond for post-construction treatment and attenutation. 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 Beaver Ck and Yadkin River basin. 4. Total Property Area: 20.0 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+: 20 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 (BUA). 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 = 78 % 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. Basin Information Drainage Area 1 Drainage Area Drainage Area Drainage Area Receiving Stream Name Beaver Creek Stream Class * C Stream Index Number * 12-108-13-1 Total Drainage Area (sf) 349,390 On-site Drainage Area (sf) 349,390 Off-site Drainage Area (sf) 0 Proposed Impervious Area** (sf) 349,390 % Impervious Area** (total) 100 Impervious** Surface Area Drainage Area 1 Drainage Area Drainage Area Drainage Area On-site Buildings/Lots (sf) 224,191 On-site Streets (sf) 0 On-site Parking (sf) 104,189 On-site Sidewalks (sf) 1,161 Other on-site (sf) 0 Future (sf) 0 Off-site (sf) 0 Existing BUA*** (sf) 352,595 Total (sf): 682,136 * Stream Class and Index Number can be determined at: http://portal.ncdenr.org/web/wq/ps/csu/classifications ** Impervious area is defined as the built upon area including, but not limited to, buildings, roads, parking areas, sidewalks, gravel areas, etc. *** Report only that amount of existing BUA that will remain after development. Do not report any existing BUA that is to be removed and which will be replaced by new BUA.
