This permit shall be effective from the date of issuance until October 2, 2021 and shall be subject to the following specified conditions and limitations: I. DESIGN STANDARDS 1. This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data. 2. This stormwater system has been approved for the management of stormwater runoff as described in Section 1.7 of this permit. The project is permitted for 44 lots/units in drainage area 1 and 14 lots/units in drainage area 2. The sand filters designated as No. 1 & 2 have been designed to treat the runoff from 98,977 and 38,215 square feet of built-upon area, respectively. The maximum allowed built- upon area for the project is 137,192 square feet. 3. The application form, supplement forms, approved plans and specifications for this project are incorporated by reference and are enforceable parts of the permit. 4. All stormwater collection and treatment systems must be located in either dedicated common areas or recorded easements. The final plats for the project will be recorded showing all such required easements, in accordance with the approved plans. Page 2 of 8 State Stormwater Management Systems Permit No. SW8 130608 5. The project shall maintain a 50' wide vegetated buffer adjacent to surface waters, measured horizontally from and perpendicular to the normal pool of impounded structures, the top of banks of each side of rivers and streams and the mean high water line of tidal waters. 6. In accordance with NCAC 02B.0233 (9) and DWR wetland permit # 2010 0396, the Division hereby grants a minor variance for that impervious surface area at the road crossings within the 50' vegetated buffer as shown on approved plans. 7. All runoff being directed into wetlands shall flow into and through those wetlands at a non-erosive velocity per 401/404 requirements. 8. The following design elements have been approved for this sand filter stormwater facility, and must be provided and maintained at design condition: Design Criteria Sand Filter#1 Sand Filter#2 a. Drainage Area, ac. 4.273 1.356 On-site, ft2 186,127 59,072 Off-site, ft2 0 0 b. Total Impervious Surfaces, ft2 98,977 38,215 c. Design Storm, inches 1.5" 1.5" d.

Stream Classification C; NSW C; NSW 8. Per Section .1008 (h) of the stormwater rules, this alternative design provides equal or better protection under the rules because it closely follows the BMP manual sections for both open and closed sand filters; thus it is considered a "hybrid" design. This design includes a curtain drain located around the perimeter of the sand filters to provide for proper drainage under high water table conditions. The design meets the requirements for surface area, volume, and drawdown time for the 1.5" design storm. In addition, the design has an adequate sediment chamber that provides diffuse flow over the weir to the top surface of the sand chamber.

U.rcla;cQra ,n "�r /�rTi� 1�4s ,i Subject: FW:The Burroughs Section II Georgette, Please reference below the email request for additional information that I sent yesterday. As we discussed,this project is similar to the School Street Center project,SW8 121110,also by the same engineering firm, Parker&Associates in Jacksonville, but with a different engineer,Tim Stewart. They are proposing to use a hybrid sand filter(closed bottom, open top)to maximize storage in the upper part of the filter due to a high SHWT. The only difference on this project is that they are not using a submersible pump in a wet well to pump out the filtered water. The main problem I see is that they propose using a curtain drain interceptor to lower the SHWT by about 2 feet in order to prevent ground water seepage into the sand filter. On the School Street Center project, the top of the concrete wall was within 8"of the SHWT and the curtain drain interceptor was only used as a safety measure. I think we should require that the concrete wall height be at a minimum elevation which is no more than 6" below the SHWT, similar to the allowance of 6" less on permanent pool of wet ponds. If we allow curtain drains around sand filters,what's next? Are we going to allow them around wet ponds, infiltration basins,etc.? I think we need to discuss the issue in more detail. Steve From: Pusey, Steven Sent:Thursday,August 22, 201312:14 PM To: Parker&Associates Subject:The Burroughs Section H Attention: Tim Stewart Tim, We do not have a way to evaluate the effectiveness of the curtain drain interceptor or how much the SHWT will be lowered by the overall built-upon area of the project. Therefore,we must ask that you keep the wall height of the concrete bottom within 6"of the SHWT,similar to the polity for wet detention ponds permanent pool elevation. 1 Previously on School Street Center,we allowed the curtain drain just as a safety factor. The wall height was only about 8"short of the SHWT. We allowed this because it was"close enough." In this case,the wall height you are proposing is 1.9'short of the SHWT for sand filter#1 and 2.3'short for sand filter#2. These walls must be brought up to within 6"of the SHWT. Also,the section view of the sand filter should be slightly different than on the School Street Center project due to the configuration. Please make the necessary adjustments and resubmit by September 12, 2013. If you have any questions or need additional time, please don't hesitate to call.

I reviewed our tiles and found a Soils Report prepared by Haywood Pittman dated February 13, 2013. It shows that at about I 0"-12"below the ground surface there is sandy clay material and that the Seasonal High Water Table (SHWT) is at 12" t from the soil surface for each sand filter. He went further to say that the actual static water level was 18" f below the surface. The bores were dug in the center of the sand filters. For Sand Filter#l, the ground elevation at the bore is 43.0 t, therefore the SHWT elevation is 42.0 t. For Sand Filter #2, the ground elevation is 45.0 t, therefore the SHWT elevation is 44.0 t. The first page of each of the Sand Filter Supplements have been revised to show the correct SHWT. 2. Per your requirement, since the SHWT elevations are higher than the top of the sand filter wall elevations, we have designed a curtain drain around the sand filters to intercept any possible ground water that might run through the soils and break out of the banks above the sand filter wall. I really don't believe that this will happen, but just in case, the curtain drain will intercept it. In addition, the entrance to Ramsey Road was revised as required by NCDOT. The revision caused the parking impervious area to increase by 261 SF. This amount was subtracted from the future impervious, so that the total impervious did not change.

II Attention: Timothy M. Stewart, PE Subject: Request for Additional Information Stormwater Project No. SW8 130608 The Burroughs,Sec. 11 Onslow County Dear Mr. Stewart: The Wilmington Regional Office received and accepted a State Stormwater Permit Application for The Burroughs Section If on 6-6-13. A preliminary in-depth review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. A soils report is required for all engineered systems,including sand filters. The report should contain the estimated Seasonal High Water Table elevation at each proposed BMP location(sand filter#1 and#2) reported in FMSL,not as a depth Below Existing Ground (BEG). If it's reported as a depth BEG the bore map must include the existing ground elevation at each bore location. 2. On sand filter#1,the estimated SHWT is 0.9' higher than the walls of the sand filter. The SHWT should be less than or equal to the wall height for this type of sand filter design. After internal discussion at this office,we cannot consider the factors involving future ground water recharge. Therefore,unless the soils test confirms a lower value for SHWT,the wall height of the sand filter will need to be raised to be at least equal to the SHWT. As discussed,on a previous project for School Street Center,we allowed a curtain drain around the sand filter to lower the SHWT by 0.7 feet. Therefore,we could consider this again if necessary. Please remember that a change to one number may have a domino effect on other numbers. Please check all plans, calculations and forms to ensure that the numbers are consistent throughout. 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 July 29, 2013,or the application will be returned as incomplete. The return of a project will necessitate resubmission of all required items,including the application fee. If you need additional time to submit the information, please mail,email 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. The construction of any impervious surfaces,other than a construction entrance under an approved Sedimentation Erosion Control Plan, is a violation of NCGS 143-215.1 and is subject to enforcement action pursuant to NCGS 143- 215.6A. Please reference the State assigned project number on all correspondence. Any original documents that need to be revised have been sent to the engineer or agent.All original documents must be returned or new originals must be provided. Copies are not acceptable.

METHOD 1) The sand filter's stage discharge relationships are calculated based on the outlet devices 2) The stage storage is determined based on pond dimensions 3) Stage discharge and stage storage curves are used to create a storage indication curve 4) Pond routing is performed by using a time span and time increment.

The 7.66 acre tract is located on Ramsey Road (SR 1324) across from the existing Carolina Forest subdivision. It is bound by Ramsey Road to the Southwest and an unnamed tributary draining to Half Moon Creek (C; NSW) that serves as the Eastern property line. The site is currently undeveloped previously cleared woodland and the existing topography is nearly level (< 2% slopes). The proposed project will involve an area of land disturbance totaling 7.1 acres and will be located within an area consisting mostly of Norfolk loamy fine sand according to the Onslow County Soil Survey. Proposed drainage for the project consists of yard inlets and catch basins inter-connected in a pipe network that ultimately discharge to two stormwater sand filters located on-site. The stormwater sand filters will act as temporary sediment basins during the construction phase. The temporary sediment basins will be cleaned out and converted to the stormwater sand filters upon final stabilization and project completion. Ofline bypass yard inlets and pipe will be provided for each sand filter to bypass runoff in excess of the 1.5" design storm. The treated stormwater will be discharged into the unnamed tributary to Half Moon Creek (CNSW) For additional information, please refer to the Plans, Stormwatcr Application, Supplement Calculations and the rest of the submittal information. c3.Forinsstormwalera*he[3urroughsll.SWNaiTative2.4.13(Iteviscd.52013) ME-CoVE JUN 0 6 2013 BY:---------- EMAIL ADDRESS: TEXT MESSAGES TO: Pzitextnbizec.rr.com MAPS AND PLANS TO: oaidrafKalbizec.rr.com • ENVIRONMENTAL ENGINEERING • STORMWATER, WATER & WASTEWATER SYSTEMS • FEASIBILITY & DEVELOPMENT CONSULTING • GLOBAL POSITIONING SURVEYS • SUBDIVISION & CONSTRUCTION PLANS PARKER & ASSOCIATES, INC.
