MCLantb Farmstead Subdivision Section I Brunswick County FOR THE construction, operation and maintenance of overall low density with a curb outlet system and 2 wet detention ponds 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. This permit shall be effective from the date of issuance until February 4, 2013, and shall be subject to the following specified conditions and limitations: 1. DESIGN STANDARDS 1. This permit is effective only with respect to the nature and volume of stormwater described in the application arid other supporting data. 2. This stormwater system has been approved for the management of stormwater runoff as described on page 3 of this permit, the Project Data Sheet. The subdivision is permitted for 60 lots, each allowed a maximum of 6,500 ftz square feet of built -upon area. 3. Approved plans and specifications for this project are incorporated by reference and are enforceable parts of the permit. 4. The uncollected portions of this project propose a curb outlet system. Each of the four designated curb outlet swales shown on the approved plan must be maintained at a minimum of 100' long with 5:1 (H:V) side slopes or flatter, have a longitudinal slope no steeper than 5%, carry the flow from a 10 year storm in a non -erosive manner, maintain dense vegetated cover, and be located in either a dedicated common area or a recorded drainage easement. 2 State Stormwater Management Systems Permit No. SW8 021024 No piping shall be allowed except those minimum amounts necessary to direct runoff beneath an impervious surface such as a road or under driveways to provide access to lots. G. Runoff conveyances other than the curb outlet system swales, such as perimeter ditches, must be vegetated with side slopes no steeper than 3:1 (H:V). 7. Each pond has been designed using the 90% TSS chart, therefore, a vegetated filter is not required. 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. 9. The overall tract built -upon area percentage for the project must be maintained at 30%, per the requirements of Section .1005 of the stormwater rules. 91 State Stormwater Management Systems Permit No. SW8 021024 DIVISION OF WATER QUALITY PROJECT DATA SHEET Project Name: Farmstead Subdivision Section I Permit Number: SW8 021024 Location: Brunswick County Applicant: Mr. W.J.
