This is a reminder that permit renewal applications are due 180 days prior to expiration. We do not have a record of receiving a renewal application. If you wish to keep this permit active please submit a completed permit renewal application along with a $505.00 fee for permit renewal. If this project has not been built and you do not wish to maintain the permit please advise. Permit application forms for renewal can be found on our website at: https://deq.nc.goy/about/divisions/energy-mineral-land-resources/energy-mineral-land- rules/stormwater-progra ost-construction. North Carolina General Statutes and the Coastal Stormwater rules require that this property be covered under a stormwater permit if the project is constructed. Failure to maintain a permit subjects the owner to assessment of civil penalties. If you have questions, please feel free to contact me at (252) 948-3923. 1 will be glad to discuss this by phone or meet with you. If you would like, I can e-mail you a copy of the application form.

The best management practice to be implemented for stormwater management is a wet detention basin. In order to confirm the design permanent pool elevation an on -site soils evaluation was conducted by the Engineer on June 30, 2006. Previous soils work was conducted in the fall of 2004 but subsequent to that activity the location of the proposed wet pond was moved to the southwest comer of the tract. Therefore, a new evaluation was performed to confirm that conditions regarding the seasonal high water table are consistent across the width of the tract. A boring was advanced to a depth of approximately 48" in the area of the proposed pond. The ground elevation at the boring site was approximately 11.5' based on the nearest recorded spot elevations. The noted soil profile characteristics are tabulated below: 0-10" - "A" horizon, medium brown loamy sand with fine roots 10"-20" — light brown sandy loam, gritty, will not ribbon 20"-32" — light brown sandy clay loam, ribbons to 4" x %x" 32" — 48" — light brown to orange sand Free water measured 43" from surface after 20 minutes, calculates to an elevation of 8.12'. For conservative design the permanent pool elevation is set at 8.5'. CARO'•..

This office received your stormwater application for the subject project on July 3, 2006. A preliminary review of the plans and specifications has been completed. Before a stomrwater permit can be issued, the following items must be addressed: 1) Provide a completed wet detention supplement sheet. 2) Provide a copy of USGS Topo, and Currituck County Soils Map with project located on each map. 2) Provide detailed stormwater narrative that describes overall project, drainage basins, - treatment measures, and design parameters. The above requested information must be received in this office prior to October 20, 2006, or your - application will be returned as incomplete. The return of this project will necessitate resubmittal of all required items including the application fee. If you need additional time to submit the required information,. - please mail or fax your request for time extension to this office at the Letterhead address.

A preliminary review of your project indicates that the application package is incomplete. The following items are needed to make the package complete: _ $420 check signature by owner on page 4 of application _ 2 sets of plans _ narrative _ supplement (wet detention, infiltration basin, low density, curb outlet system, off -site system, underground infiltration trench) signature by owner on supplement form t/soils report We are returning the entire package to you. Once the package is complete you may resubmit. You should also be aware that the Stormwater Rules require that a permit be issued prior to any development activity.

V The project is to be constructed on a 3.83 acre tract which was formerly used for a retail facility. All existing buildings and pavement are to be removed. The proposed improvements consist of 14 units in three separate buildings, comprising 35,256 s.f, v drive aisles, parking areas and sidewalks comprising an additional 70,250 s.f. bringing the total impervious surface area to 105,506 s.f. The best management practice (BMP) chosen for the project is wet detention. Although the State requirement for storage volume is the capacity to detain the run-off from a 1" rainfall event, the design storm event was 2" in order to better satisfy the County Unified Development Ordinance. The final wet pond design resulted in a temporary pool volume equating to a 2.26" rainfall ✓ event as set forth in the attached WET DETENTION BASIN DESIGN NOTES AND CALCULATIONS. Also adding to the conservative nature of the design is the use of 64% in the Schuler Equation as opposed to the actual impervious coverage of 63.3%. Stormwater runoff will be conveyed to the wet detention pond via sheet flow across paved areas and roof tops to a curb and gutter collection system. No subsurface storm sewers are proposed. The pond is designed for 90% TSS removal. The discharge structure entails a 1 ''/2" orifice which will draw down the temporary pool resulting from the design storm in 3.38 days, approximately 81 hours. There is a drainage ditch existing along the rear property line. The centerline of this ditch is essentially coincidental with the rear property line. This ditch flows generally north to south until it reaches the south west corner of the subject tract, from which point it turns to the west and traverses approximately 0.3 miles to its outfall in the Albemarle Sound. The ditch is heavily vegetated throughout its course downstream of the subject tract.
