The number of permitted lots has been revised to allow for construction of 24 lots at 3,100 square feet of built -upon -area (BUA). Please not that the project total BUA remains the same at 129, 373 square feet. We are forwarding revised Permit No. SW6090902, dated November 2, 2009, for the construction, operation and maintenance of the subject project and the stormwater B M Ps. This pe'rm:c shall be effective from the date of issuance until November 2, 2019, and shall be subject to the conditiuns and limitations as specified therein. Please pay special attention to the Operation and Maintenance requirements in this permit. Failure to establish an adequate system for operation and maintenance of the stormwater management system will result in future compliance problems.

This project is permitted for a maximum of 129,373 square feet of BUA. 3. The stormwater systems proposed to treat the runoff generated by the designated high density areas have been approved forthe management of stormwater runoff as described in Section 1.6 on page 3 of this permit. 4. The subdivision is permitted for 24 lots, each allowed a maximum of 3,100 square feet of built -upon area. 5. The low density portions of this project will maintain a minimum 30 foot wide vegetated buffer between all impervious areas and surface waters. 6. Within the low density portions of the permitted project, the only runoff conveyance systems allowed will be vegetated conveyances such as swales with minimum side slopes of 3:1 (H:V) as defined in the stormwater rules and as shown on the approved plan.

Design Summary, Page 2 of 2 High Density Residential Subdivisions Deed Restrictions & Protective Covenances In accordance with Title 15 NCAC 2H.1000, the Stormwater Management Regulations, deed restrictions and protective covenants are required for High Density Residential Subdivisions where lots will be subdivided and sold and runoff will be treated in an engineered stormwater control facility. Deed restrictions and protective covenants are necessary to ensure that the development maintains a "built -upon" area consistent with the design criteria used to size the stormwater control facility. I, Q AS A ?tiara , acknowledge, affirm and agree by my signature below, that I will cause the following deed restrictions and covenants to be recorded prior to the sale of any lot: 1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number as issued by the Division of Water Quality under NCAC 2H.1000. 2. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the stormwater management permit. 3. These covenants are to run with the land and be binding on all persons and parties claiming under them. 4. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Water Quality. 6. The maximum allowable built -upon area per lot is 3166 square feet. This allotted amount includes any built -upon area constructed within the lot property boundaries, and that portion of the right-of-way between the front lot line and the edge of the pavement. Built upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does hot include raised, open wood decking, or the water surface of swimming pools. OR, if the proposed built -upon areas per lot will vary, please REPLACE #6 above with the following: 6. The maximum built -upon area per lot, in square feet, is as listed below: Lot # BUA Lot # BUA Lot # BUA Lot # BUA This allotted amount includes any built -upon area constructed within the lot property boundaries, and that portion of the right-of-way between the front !ot line and the edge of the pavement. Built upon area includes, but is not limited to, structures, asphalt, concrete, gravel, brick, stone, slate, coquina and parking areas, but does not include raised, open wood decking, or the water surface of swimming pools. All runoff from the built -upon areas on the lot must drain into the permitted system. This may be accomplished through a variety of means including roof drain gutters which drain to the street, grading the lot to drain toward the street, or grading perimeter swales to collect the lot runoff and directing them into a component of the stormwater collection system. Lots that will naturally drain into the system are not required to provide t se addition l measures.

This maintenance record will be kept in a log in a known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. The wet detention basin system is defined as the wet detention basin, pretreatment including forebays and the vegetated filter if one is provided. This system (check one): ❑ does ® does not incorporate a vegetated filter at the outlet. This system (check one): ❑ does ® does not incorporate pretreatment other than a forebay. Important maintenance procedures: — Immediately after the wet detention basin is established, the plants on the vegetated shelf and perimeter of the basin should be watered twice weekly if needed, until the plants become established (commonly six weeks). — No portion of the wet detention pond should be fertilized after the first initial fertilization that is required to establish the plants on the vegetated shelf. — Stable groundcover should be maintained in the drainage area to reduce the sediment load to the wet detention basin. — If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the emergency drain should be minimized to the maximum extent -practical. — Once a year, a dam safety expert should inspect the embankment. After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance should be kept in a known set location and must be available upon request. Inspection activities shall be performed as follows.
