The corresponding drawdown time of 4.2 days is also what is reported on page 2 of the supplement. The page 7 calculation using the 7.58' elevation demonstrates that the orifice draws down satisfactorily for both the 1.5 and 2.0 rainfall events.

Instead of 7.58, you should be using 7.75. The drawdown talcs should be based on the provided head for the next available outlet along with the minimum required volume. I have attached an old drawing that may help. Please let me know if you have questions. (If I remember correctly, this is one of the items I mentioned that also needs to be fixed on the 1747 project) Can you e-mail the updated page of the talcs and supplement for 313?

The temporary pool area is 2,725 SF. See calculation pages 5 &6 for clarification. 2. See top of calculation sheet 8/12 for drawdown time for the temporary pool elevation of 7.75'. The drawdown time is 4.2 days. 3. 1 have changed the forebay volume calculations to adjust for the error of using a 0.5' vs. 1.0' increment. This change also carried over to the % forebay volume which was also adjusted on the supplement. 4. With the lowered temporary pool to 7.75' vs. 8.0', I also changed the weir elevation. have attached revised plan sheets with this change along with the pond volume data and pool level data. I also rerouted the storms to show that the pond could still handle the design storms, which it does. The only significant change is that the 10-yr stage is now down from 8.14' to 8.0'. We appreciate your assistance with this project. Should you have any questions, please do not hesitate to give me a call.

Davis, PE, CPM Director September 30, 2013 Commanding Officer MCB Camp Lejeune c/o Neal Paul, Deputy Public Works Officer Building 1005 Michael Road Camp Lejeune, NC 25842 Subject: Request for Additional Information Stormwater Project No. SW8 130907 Parking Lot Addition, Building 313 Onslow County Dear Mr. Paul: Pat McCrory, Governor John E. Skvarla, III, Secretary The Wilmington Regional Office received an Express Stormwater Management Permit Application for the Parking Lot Addition, Building 313 on September 11, 2013 with additional information submitted on September 24, 2013. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue theestormwater review: 1. Please confirm the surface area and volume associated with the temporary pool elevation. The temporary pool elevation, considered to be the elevation of the next available outlet, appears to be set at 8.0 ft. The supplement indicates that the temporary pool surface area and volume is 4,049 ft2 and 2,028 ft3, respectively. However, the calculations indicate that the surface area and volume provided at an elevation of 8.0 ft is 4,393 ft2 and 3,771 ft3, respectively. 2. Please confirm the drawdown calculations presented on page 7 of the calculations. It appears that the temporary storage elevation (8.0 ft) was not used in the drawdown calculations; instead the minimum required storage elevation appears to have been / used. Please confirm the volume provided in the forebay. On page 4 of the calculations, it appears that a depth of 1 ft was used when determining the volume of the forebay between elevations 3.5 ft and 4.0 ft. Due to the relatively minor nature of these comments, the express additional information review fee has been waived. Please keep in mind that changing one number may change other numbers and require the calculations, supplements, and other supporting documentation to be updated. Verify all numbers are correct to ensure consistency in the application documents. Please note that this request for additional information is in response to a preliminary review. The requested information should be received in this Office prior to October 8, 2013, 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 email or fax your request for a time extension to the Division at the address and fax number at the bottom of this letter. Please note that a second significant request for additional information may result in the return of the project. If the project is returned, you will need to reschedule the project through the Express coordinator for the next available review date, and resubmit all of the required items, including the application fee.

Corrected the total BUA in the second table to read 16,502. 2. Corrected page I and 4 of the supplement. Top of sediment elevations are o.5' for the main pond and 2.5' for the forebay. , 3. Changed the temporary pool volume to be that associated with the 1.5 inch storm vs. the 2 inch storm. I have attached revised supplement pages. 4. Changed page 8 of the calculation sheet to use 8.0' vs. 7.99' in calculating the orifice driving head. The pond draws down within 2-5 days for both the 1.5 and 2.0 inch storms. 5. The adjacent ditch is not a surface water feature. We appreciate your assistance with this project. Should you have any questions, please do not hesitate to give me a call.

Stormwater Management Narrative Construct Parking Lots, Hadnot Point and French Creek MCB Camp Lejeune, NC Building 313 This project proposes to construct a new asphalt paved parking area in an existing grassed area. The parking area will be an extension of an existing parking lot. The site is located in an older area of the base with no surrounding stormwater boundaries. The runoff from the existing impervious areas, with the exception of 642 SF of street/sidewalk area, around the site will be diverted around the drainage basin for the new parking area. The project will convert 15,860 SF (0.364 Ac.) of grassed area into asphalt parking area. The drainage boundary established for this project is 25,107 SF in size. The BUA consists of 15,860 SF of new parking area and 642 SF of existing BUA. The project built -upon area percentage is 65.73. Stormwater treatment will be by a wet pond sized for 90% TSS. The SA/DA ratio is 7.63%. The pond average depth is 3.0 feet and it is sized to contain and drawdown the runoff volumes associated with both the 1.5 and 2.0 inch storms. The minimum required pond surface area is 1,916 SF compared to the 2,732 SF provided. The work area does not impact any wetlands. The pond and parking area are located in a managed lawn area that is not regulated by the US Army Corps of Engineers. The site drains to the New River which is classified as SC;NSW (Index #19-(15.5)). All work is located greater than fifty feet from surface waters. 1.5 acres of the site will be disturbed by this project in order to construct the parking area. The sedimentation and erosion control plan is being concurrently submitted. The soils on the site are classified as Baymeade by the Onslow County Soil Survey. Baymeade is described as a loamy sand at the depths to be disturbed by this project. The property is owned by the Federal Government. There are not any known historic sites on the property. yy � I Al�Mc�^j Y. �,r 1� r SEP 11 2013 w ✓ f heaA 13 'M)nvei 03 ieuyie, *Tank 4- 'BA :4 A eSW Tani -'Sphng KiR w All .1 n'N. 3-D TopoQuads COpyright 0 1999 DeTAM yamuth, M 04006 Bounce Data: ISGS 14%fe'-sa;ed 25',400(yD!talli 13-0 Data: IGS14 A SE? 11 2013 FC - 313 � b ,��a Yr � JIi gar C� n�i4 rs> � rF .,.,F°N QUA NCDENR North Carolina Department of Environment and Natural Resources Request for Express Permit Review FILL-IN all the information below and CHECK the Permit(s) you are requesting for express Coordinator along with a completed DETAILED narrative, site plan (PDF file) and vicinity r of the project location.
