It is currently vacant and is zoned General Business. Construction will consist of one (1) new building a parking lot, one (1) storm water infiltration basin, an underground piping system and the installation of required landscaping. The proposed building will contribute 7,500 sf of impervious area. The parking will contribute another 26,733 sf and the concrete sidewalk and dumpster pad will be 1 176 sf. The maximum impervious area will be 0.81 acres or 43% of the overall site. According to the Pasquotank County Soils Maps as prepared by USDA, Soil Conservation Service, the soils on this site are Seabrook, Dorovan, and a small area of Arapahoe. One soil boring was performed in the area of the detention pond by Sean C. Robey, PE and Kimberly Hamby on May 21, 2007. The soil boring was conducted with and AMS 2-3/4" diameter 6' long hand mud auger. The boring 1 was located within the area of the proposed detention pond. The elevation at this location is approximately 6.3'. The first 6" was topsoil. From 6-42" was a sandy loam. At 42", we encounter sand that became lighter in color and wet at 48". This does correspond with the Seabrook classification. Based upon our findings, we estimate the Seasonal High Water table to be approximately elevation 2.5'. The bottom elevation of the infiltration basin will be 4.5'. Drainage Area 1 contains 1.06 acres and encompasses a majority of the site including all proposed impervious areas. This drainage area will contain 7,500 sf of building. It also contains 26,733 sf of pavement and 1,176 sf of concrete. The total impervious area will be 35,409 sf or 76.47% of the drainage area. Runoff from the building will be collected by a downspout collection system and routed through an underground pipe system which discharges into a vegetated swale that provides a collection point and some pre-treatment before entering the infiltration basin by topping Level Spreader #1. The runoff from the parking lot will sheet flow across the parking lot to various drop inlets. It will then be routed through the same underground piping system as the building and discharge into the vegetated swale. The invert of the vegetated swale is 4.0'. A level spreader with a top elevation of 5.25' will evenly distribute the flow into the infiltration basin. The first inch of runoff from the site, 3,006 cf, is stored between the bottom of the basin at, 4.5' and elevation 5.35 The bypass, Level Spreader #2, is located in the end of the vegetated swale. The top elevation of Level Spreader #2 is 5.70', which is approximately 2 inches above existing grade. This elevation provides 4,963 cf of storage. The minimum infiltration rate for the Seabrook soil is 6" per hour. At a maximum storage depth of 14.4", this basin should draw down approximately 2.4 hours (14.4"/6" per hour). Runoff in excess of this storage volume will discharge through the bypass into the swamp of Knobbs Creek. We modeled the site utilizing XPStorm, Storm and Wastewater Management Model. Printouts from the model have been attached to this report. The model was run for 24 hours with a Type III rainfall distribution for a 5.75 inch 24 hour storm. Conduit Infil simulates the 6 inch per hour infiltration rate out of the infiltration basin, Node IB. The infiltration rate was determined based on 6" per hour X 3618 sf (the area of the bottom of the basin). 3618 sf X 0.5'/hr 3600 s/hr = 0.5025 cfs A stage -time graph for Node IB shows that the basin only contains standing water for a 7 hour period during the storm. Conduit LS-2 represents Level Spreader #2. The maximum flow across Level Spreader #2 during the 10-year storm is 0.98 cfs. Construction sequencing and notes on the plan direct the contractor to construct the infiltration basin and leave it "off-line" until construction is complete. This is to be accomplished by construction of a temporary ditch from the swale location to the wetlands. This ditch will remain in place until the site is paved. Then Level Spreader #2 will be installed, forcing the stormwater runoff to fill the swale and top Level Spreader #1 into the infiltration basin. Drainage Area 2 contains the remaining 0.86 acres which consists mostly of wetlands. These areas will continue to drain to the wetlands and will not contain impervious areas. Rational method analysis indicates a pre development 10 year peak runoff of 2.7 cfs. The post development runoff into the swale is 4.14 cfs. Based upon the infiltration rate of the soil, the discharge from the by-pass during a 10-year storm will not exceed 1 cfs. The total disturbed area for this development will not exceed 1.9 acres. Limits of disturbance have been shown on the plans. Mr. Ernest Odei-Larbi Dept. of Environment and Natural Resources Water Quality Section 943 Washington Square Mall Washington, NC 27889 Subject: Stormwater Review SW7070818 LFM — Hughes and Halstead Project # 060564 Dear Mr. Odei-Larbi: H Y M A N ■ ROBEY- November 28, 2007 t09F.re► E''gED NOV 2 2007 DWQ-WARD Please accept the following information in response to your letter dated October 10, 2007. Comment 1. As you stated in your email, this item is no longer an issue. Comments 2 & 3. These items are both related to the design of a level spreader for the by-pass of the infiltration basin. I have attached documentation from our XPStorm model of the project. This model indicates that there will be a peak discharge of 0.98 cfs discharge through the bypass during a 10 year storm event. Based on this discharge rate, the bypass weir has been replaced by a 13' level spreader with a 30' vegetated filter strip. The plans and project description have been updated accordingly. The original and one copy of the Level Spreader Worksheet and the Maintenance Agreement are enclosed. Comments 4. Mrs. Norrell's title is "manager". I have enclosed a printout from the Secretary of State's website showing the managers and members of the LLC. Comment 5. Drop inlet B has an invert of 4.45 and Drop inlet C has an invert of 4.30. The slope on the pipe is 0.15%. Comments 6 & 7. The drawdown time of 2 hrs was based on a maximum storage depth of 12 inches and a drawdown rate of 6 inches per hour. I have enclosed two copies of each of the following: volume calculations (spreadsheet), revised project description, and revised pages 1 and 2 of the Infiltration Basin Supplement. Comment 8. It was intended that the Level Spreader at the Infiltration Basin be used as the benchmark. This was stated in an attachment to the Infiltration Basin Supplement that you indicated was not included in your package. I have enclosed two copies of this attachment and the benchmark has been indicated on the revised plans. Comment 9. There is no swale design in this project. The swale is only for collection of stormwater prior to topping the level spreader into the infiltration basin. Comment 10. I have enclosed copy of the county soils map and a colored map from the Pasquotank County website that shows the parcel limits and soil classifications. Comment IL The water table is the Seasonal High Water Table. Please refer to the revised Project Description. Thank you for your assistance with this project. If you need additional information or have any questions, please do not hesitate to call this office at (252) 335-1888. Sincerely, Sean C. Robey, P.E. ^ -- W ry Kimberly D.

It was fortunate that I found this while preparing billing statements. We have new clerical staff that filed the letter instead of passing it on to me. I feel that I can address these items in about two weeks. Due to the Thanksgiving holiday, I would like to request an extension until Monday, December 3rd. I have copied Scotton this letter just to make sure you receive it. I will be contacting you in the near future to discuss several of the items you have requested.
