DESIGN STANDARDS This permit is effective only with respect to the nature and volume of stormwater described in the application and other supporting data. This stormwater system has been approved for the management of stormwater runoff as described in Section 1.8 of this permit. The runoff from all built -upon area within the permitted drainage area(s) of this project must be directed into the permitted stormwater control measure(s). The stormwater control measure has been designed to handle the runoff from 418,899 square feet of impervious area. Page 1 of 7 Post -Construction Stormwater Management Permit No. SW8 140416 3. The subdivision is permitted for 69 lots, each limited to a maximum of 4,500 square feet of built -upon area. 4. The maximum built -upon area allowed for the entire subdivision is 418.899 square feet. 5. The drainage area will be limited to the amount of built -upon area indicated in Sections 1.3 and 1.8 of this permit, and per approved plans. 6. A 50' wide vegetative buffer must be provided and maintained adjacent surface waters, measured horizontally from and perpendicular to the normal pool of impounded structures, the top of bank of both sides of streams and rivers and the mean high-water line of tidal waters. All runoff being directed into wetlands shall flow into and through those wetlands at a non -erosive velocity. 8. The following design criteria have been permitted for the wet detention pond and it must be provided and maintained at the design condition. Pond 1 a.

SCHEDULE OF COMPLIANCE No person or entity, including the permittee, shall alter any component of the approved stormwater system shown on the approved plans unless and until the Division has approved of the revised plan. 2. The stormwater management system shall be constructed in its entirety, vegetated and operational for its intended use prior to the construction of any built -upon surface. Page 2 of 7 Post -Construction Stormwater Management Permit No. SW8 140416 During construction, erosion shall be kept to a minimum and any eroded areas of the system will be repaired immediately. If the stormwater system is used as an Erosion Control device, it must be restored to design condition prior to operation as a stormwater treatment device, and prior to occupancy of the facility. 4. Prior to the sale of any lot, the following deed restrictions must be recorded: a. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number SW8 140416. as issued by the Division of Energy, Mineral and Land Resources under NCAC 2H.1000. b.

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.

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, Michael H. Pollak, acknowledge, affirm and agree by my signature below, that I will cause the following deed restrictions and covenants to be recorded for Wvndwater - Phase 2 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 the Stormwater Management Regulations. 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 4,500 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 not 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 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 not include raised, open wood decking, or the water surface of swimming pools. Each lot will maintain a 30** foot wide vegetated buffer between all impervious areas and surface waters. **50 foot for projects located in the 20 coastal counties. 8. 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 these additional measures.
