Honeycutt Engineering Post Office Box 15036 Wilmington, North Carolina 28408 Subject: ADDITIONAL INFORMATION Stormwater Project No. SW8 960510 American Legion Post 10 New Hanover County Dear Mr. Honeycutt: The Wilmington Regional Office received previously requested information for the Stormwater Management Permit Application for American Legion Post 10 on June 28, i996. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review: 1. You have still not taken advantage of the natural topography for the construction of the vegetated filter. Since the invert of the outlet pipe is 22.5, the best place to construct the filter is parallel to the 22 contour, allowing natural sheet flow over the existing contours, and deleting the need to excavate a channel all the way down. These are SA waters, and the less construction that takes place close to the water, the better. 2. The permit application proposes 1.49 acres of impervious area, the calculations show 1.247 acres, while I add up 1.51 acres based on your numbers. Please clarify. 3. The State has authorized use of an alternative calculation method for determining the runoff volume to be treated. I have enclosed a copy. If you wish, you may use this method for both detention and infiltration. 4, You must provide a bypass for the excess runoff prior to entering the pond. The ouverflow spillway channel can be looped around the pond and a structure provided at the inlet swale which will divert the runoff. 127 Cardinal Drive Extenaion, Wilmington, N.C. 2&WS-3845 • Telephone 910-395-3900 • Fax 910-350-2004 An Equal Opportunity Affirmative Action Employer Mr. Honeycutt July 24, 1996 Stormwater Project No. SWS 960510 5. The volume calculation appears to be arrived at by subtracting the rear area from the total area, however, the total area has already had the rear area subtracted from it once before. The volume is based on the total drainage area to the pond. Based on the impervious totals you have provided, the volume in the pond is deficient. 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 August 24, 1996, 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 have any questions concerning this matter please feel free to call me at (910) 395-3900.

Hunt, Jr. DIVISION OF ENVIRONMENTAL MANAGEMENT Jonathan B. Howes Governor WATER QUALITY SECTION Secretary May 30, 1996- Mr. Jim Honeycutt, P.E. Honeycutt Engineering Post,Office Box 15036 Wilmington, North Carolina 28408 Subject: ADDITIONAL INFORMATION Stormwater Project No. SW8 960510 American Legion Post 10 New Hanover County Dear Mr. Honeycutt: The Wilmington Regional Office received a Stormwater Management Permit Application for American Legion Post 10 on May 8, 1996. A preliminary review of that information has determined that the application is not complete. The following information is needed to continue the stormwater review. The site proposes a concentration of impervious area and a collection system that preclude permitting under the low density option. In order to qualify for a detention pond to treat the runoff, you must provide the results of a chlorides test taken at a point in the receiving waters that is outside of a 112 mile arc drawn from the point of release. If the test comes back at > 500 ppm, your only option for the site, as proposed, is an infiltration pond. If the test comes back at C 500 ppm, the city pond you show can be modified to meet State requirements. 2. The City's requirements for flood control cannot supersede the State's requirments for low density, i.e, the City cannot require a flood control pond that outlets to SA waters for a project that submits to the State tinder the low density option. The State cannot allow outlets to SA waters, and cannot allow the collection of runoff under the low density option. 3. A signed Operation and Maintenance Plan for the stormwater control 4. If infiltration is indicated, a soils report indicating the depth to the seasonal high water table, soil type, and expected infiltration rate must be included. 127 Cardinal Drive Extension, Wilmington, N.C. 28405-3845 • Telephone 910-395-3900 • Fax 910-350 2004 An Equal opportunity Affirmative Action Employer Mr. Honeycutt May 30, 1996 Stormwater Project No. SW8 960510 5. If an engineered system is to be permitted, an additional $160.00 must be submitted to complete the entire application fee of $385.00. 6. If necessary, due to the changes in the permit option, please submit a revised application form. 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 30, 1996, or the application will be returned as incomplete.
