September 29, 2004 Ms. Rhonda Hall 2004 NCDENR BY: 127 Cardinal Drive Extension Wilmington, NC 28403 Re: SeaWatch Sale Center — SW8 040622 Dear Ms. Hall: Enclosed for your review and approval are the additional information items requested in your transmittal dated September 17, 2004 for the above referenced project. We have addressed all your comments and offer the following replies as per your item numbers: 1. The vegetated filter and level spreader are shown on the plans with a detail and spot elevations. Included are two copies of the revised plans. 2. The outlet structure is shown on the revised plans as well as a detail. Just to clarify our design, no outlet structure is proposed other than the draw down orifice, principle spillway for attenuation due to Brunswick County ordinance and the emergency spillway. All these items are built into the berm or basin dam. We have used this type of design on other projects. 3. We have revised the orifice size per your comment. Included are copies of the revised Page 3 Calculations and the revised Wet Detention Basin Supplement. 4. The pond bottom is shown as 34.0'msl on the revised Wet Detention Basin Supplement. 5. We have revised the depth readings at which sediment shall be removed on the Wet Detention Basin Supplement. Thank you for your consideration in this matter.

Linda 1 of 1 6/22/2004 12:56 PM Project Narrative General: MAS Properties and Coastal Communities are proposing to construct a residential sales center for the SeaWatch at Sunset Harbor Subdivision. The sales center will be located off NC 211 approximately 0.36-miles east of Sunset Harbor Road (SR 1112) on a 3-acre tract. The SeaWatch Subdivision is located approximately 7-miles away on Sunset Harbor Road. The sales center will be used by employees and prospective buyers. Erosion Control: The existing site is relatively flat with existing ditches that are located along the perimeters of the property lines. Land disturbance will be limited to approximately 2.E-acres. All sedimentation will be contained on site by utilizing site fencing and the stormwater pond. The stormwater pond will be utilized as a sedimentation basin during construction. All disturbed area will be either grassed, landscaped, paved or built upon as soon as possible. Stormwater Management: NCDENR and Brunswick County stormwater permits are required for this project. The wet pond design will serve as a water quality and quantity pond. The pond is approximately 10-times oversized due to site fill requirements and the desire to make the pond an amenity to the site. Therefore, the pond designed may not appear to meet the 3 to 1 flow length rule. However, by superimposing the required pond surface area (as shown on the plan) it is obvious the pond meets all regulations. The pond will discharge to an existing ditch that ultimately transports the treated water to Mercer Mill Pond Creek with is SGewafers. ere are no wetlands on this site. The proposed impervious is 25$% over the 3-acre project boundary. - State Stormwater Management Systems Permit No. SW8 040622 E STATE OF NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES DIVISION OF WATER QUALITY STATE STORMWATER MANAGEMENT PERMIT HIGH DENSITY DEVELOPMENT In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as amended, and other applicable Laws, Rules, and Regulations PERMISSION IS HEREBY GRANTED TO Sheldon Tucker, MAS Properties, LLC Seawatch Sales Center Brunswick County FOR THE construction, operation and maintenance of a wet detention pond in compliance with the provisions of 15A NCAC 2H .1000 (hereafter referred to as the "stormwater rules') and the approved stormwater management plans and specifications and other supporting data as attached and on file with and approved by the Division of Water Quality and considered a part of this permit.
