I need a few items to finish the review. 1. Please provide a drainage delineation map showing what goes to the pond and what• sheet flows off the site. 2. It looks like part of the parking area will bypass the drop inlet and flow directly into the main pond. Please show that the runoff from the parking area will make it into the drop inlet or be directed to the forebay. You may want to berm up the area between the drop inlet and the pond to direct the water into the inlet. 3. The basin length to width ratio must be greater than 3.1. 4. Please bring the inlet pipe through the bank of the pond. Do not let it discharge through the shelf separating the forebay from the main pond. Try to locate it as far away as possible from the weir separating the forebay and the main pond. 5. The applicant has to be an entity/person that can be responsible for the project. Since CW Properties is not registered as a corporation, please list Mr. Coleman as the applicant on the application form. 6. The application states that there is future impervious area of 230,488 square feet.

Low density projects should not have a discrete stormwater collection system as defined by 15ANCAC 2H .1002(18). Low density requirements and density factors can be found in 15A NCAC 2H .1005 through .1007. I. PROJECT INFORMATION Project Name: Porta-Nails, Inc. Expansion Contact Person: Jerry D. Coleman, Sr. Phone Number: (910) 762-6334 Number of Lots: 1 Allowable Built Upon Area Per Lot*: 332,340 SF * If lot sues are not uniform, attach a table indicating the number of lots, lit sizes and allowable built upon area for each lot. The attachment must include the project name, phase, page numbers and provide area subtotals and totals. 11. BUILT UPON AREA See the Stormwater Management Permit Application for specific language that must be recorded in the deed restrictions for all subdivisions. For uniform lot sizes, complete the following calculation in the space provided below where: • SA Site Area — the total project area above Mean High Water. Wetlands may be excluded when the development results in high density pockets. • DF Density Factor — the appropriate percent built upon area divided by 100. • RA Road Area — the total impervious surface occupied by roadways. • OA Other Area — the total area of impervious surfaces such as clubhouses, tennis courts, sidewalks, etc. • No. Lots — the total number of lots in the subdivision. • BUA/Lot — the computed allowable built upon area for each lot including driveways and impervious surfaces located between the front lot line and the edge of pavement. Form SWU-104 Version 3.99 Page 1 of 2 Calculation: (1,107,803 SF x 0.3) - 0 (SA x DF ) — RA — OA = BUA No. Lots Lot = 332,340 SF II.

Klimek, P.E.,Director ___—___Division-ofWater-Quality-- May 22, 2003 Subject: REQUEST FOR ADDITIONAL INFORMATION Stormwater Project No. SW8 030401 Porta-Nails, Inc. Expansion Pender County The Wilmington Regional Office received a Stormwater Management Permit Application for Porta-Nails, Inc. Expansion on April 1, 2003. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stornwater review: Even though the project meets the low -density criteria overall, the construction of the parking lot, building, and roads create a pocket of high density. The project must be designed to meet the applicable high -density requirements for this area. Please provide dimensions for the building. 3. Please dimension all the property lines. I am unable to find a CW Properties that is registered with the State of North Carolina. Porta-Nails, Inc. is a registered corporation with the State of North Carolina. If the applicant is a corporation, it must be registered with the State. Please note that this request for additional information is in response to a preliminary review. The requested information should be received by this Office prior to June 22, 2003, or the application will be returned as incomplete. The return of a project will necessitate resubmittal of all required items, including the application fee. If you need additional time to submit the information, please mail or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. The request must indicate the date by which you expect to submit the required information. The Division is allowed 90 days from the receipt of a completed application to issue the permit. N. C.
