Andrew and Kuske Engineers 902 Market Street Wilmington, NC 28401 Subject: ACKNOWLEDGEMENT OF RECEIPT AND REQUEST FOR ADDITIONAL INFORMATION Stormwater Project No. SW8 911001 Modification Calabash Presbyterian Church Brunswick County Dear Mr. Norris: The Wilmington Regional Office received a modification to the Stormwater Management Permit Application for Calabash Presbyterian Church on September 30, 1998. 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. Please add the 58' dimension of the permanent pool to the plans. 2. Please complete the tables in Section III, #6 of the permit application. The proposed impervious has not been filled in or broken down. 3. A large portion of the runoff will enter the pond at the elongated forebay area along the eastern edge of the property, but the outlet structure is proposed to be located across from the forebay along the short edge of the pond. Short-circuiting of the runoff is a concern. The design of a functional pond must provide a pond that is narrow at the inlet (a single inlet is preferred) and widens and deepens toward the outlet. The flowpath for the runoff must be at 3:1. Please either relocate the inlet to provide a single inlet, or artificially create a longer flow path by adding a berm or bulkhead. 4. On the supplement form, item f, the emergency drain, is not n/a. Due to the flat grades in this part of the state, a portable pump must be provided as the emergency drain. 5. Please label Highway 17 and a few other roads on the location map. 6. Please provide dimensions for the existing parking area and sidewalks. 7. Please provide the existing contours. 127 Cardinal Dr.Ext.,Wilmington,North Carolina 28405 'telephone 910-395-3900 FAX 910-350-2004 An Equal Opportunity Affirmative Action Employer 50%recycled/10%post-consumer paper Mr. Norris November 14, 1998 Stormwater Project No. SW8 911001 Modification ---------------------------------------------- 8.

The project was previously permitted as a low density project. The permit will be modified as a retention pond system to accommodate future building plans. The drainage area to the stormwater retention pond consists of 5.0 acres, of which 3.25 acres is existing and future impervious. The overflow from the pond will pass out the outlet structure to an existing ditch. There are no wetlands on the site and this is noted on the plans. Stormwater runoff will be directed to the pond by an existing pipe system. The 2-5 day drawdown water will leave the pond through a 1 1/2" orifice. The stormwater retention pond will be designed for 90% TSS removal and will store and release the 1st one-inch of volume of rainfall within a period of 2 to 5 days. The stormwater collection system and pond will also be designed for a 10-year storm event. �TORMWATER D E C E I V E SEP 3 01998 D D E M PROJ # Date Design Andrew and Kuske Sheet .>/J/I 902 Market St. CONSULTING ENGINEERS, INC.
