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, Emil Viola, 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 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 The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. 5.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 built -upon area per lot, in square feet, is as listed below: Lot Max BUA Number (sf) 1-D 7,843 2-SF AA I 9,952 3-SF AA 8,755 4-P 7,698 5-P 6,434 6-D 7,560 7-P 6,686 8-P 6,416 9-P 6,300 10-D .6,600 11-SF 7,435 12-P 6,980 13-P 6,438 14-P 5,942 15-SF 6,678 16-P 7,139 17-P 5,896 18-P 6,313 19-D 7,647 20-P 6,374 21-P 7,474 22-P 6,188 23-P 6,479 24-P 6,004 25-P 6,155 26-P 7,212 DEC IS 2 010 FormDRPC-3 Rev.2 05Nov2009 Page 1 of 27-P 6,458 28-P 6,402 29-P 5,610 30-P 5,610 31-D 7.652 34-P 5,874 35-P 5,879 36-P 7,157 37-P 6,176 38-P 7,105 39-P 5,760 40-P 5,760 41-P 7,105 42-P 5,705 43-D 7,180 44-P 6.358 47-D 7,548 48-D 7,110 49-P 5,767 50-SF 6,941 51-P 6,300 52-P 6,300 53-P 6,300 54-SF 6,915 55-D 8,069 56-P 7,496 57-P 6,704 58-D 7,916 59-P 6,209 60-P 6,211 61-SF AA 8,215 62-P 5,591 63-P 5,649 64-P 6,470 65-P 6,211 66-P 6,209 67-SF 7,544 68-P 6,401 69-P 6,401 70-P 7,513 71-D 10,171 72-SF 8,042 73-P 6,489 74-P 6,696 75-P 7,720 76-D 10,165 77-P 6,897 Form DRPC-3 Rev.2 05Nov2009 Page 2 of 4 High Density Residential Subdivisions Form DRPC-3 Rev.2 05Nov2009 Page 3 of 4 High Density Residential Subdivisions Deed Restrictions & Protective Covenances 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 50 foot wide vegetated buffer between all impervious areas and surface waters with the exception of Lot 107-SF-AA and Parcel A Clubhouse. 8. All runoff from the built -upon areas on the lot must drain into the permitted system except where existing conditions prevent it. 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.

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.
