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 SW7070911, as issued by the Division of Water Quality under NCAC 2H.1000. The State of North Carolina is made a beneficiary of these covenants to the extent necessary to maintain compliance with the Stormwater Management Permit. c. These covenants are to run with the land and be binding on all persons and parties claiming under them. The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Water Quality. e. Alteration of the drainage as shown on the approved plans may not take place without the concurrence of the Division of Water Quality. The maximum built -upon area per lot is (see Exhibit A) square feet.

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. Lots within CAMA's Area of Environmental Concern may be subject to a reduction in their allowable built -upon area due to CAMA regulations. All runoff on the lot must drain into the permitted system. This may be accomplished through providing roof drain gutters, which drain to the street, grading the lot to drain toward the street, or grading perimeter swales and directing them into the pond or street. Lots that will naturally drain into the system are not required to provide these measures. The approved Operation and Maintenance Plan(s) must be followed in its entirety and maintenance must occur at the scheduled intervals, including reporting where applicable. j. All roof drains must terminate at least 50 feet from the mean high water mark. Projects covered by this permit will maintain a minimum 50-foot wide vegetative buffer between all impervious built -upon areas and surface waters. Built -upon area in excess of the permitted amount will require a permit modification. Page 5 of 9 State Stormwater Management Systems Permit No. SW7D70911 17. A copy of the recorded deed restrictions must be submitted to the Division within 30 days of the date of recording the plat, and prior to selling lots.

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. Important maintenance procedures: — Immediately after the filter strip is established, any newly planted vegetation will be watered twice weekly if needed until the plants become established (commonly six weeks). — Once a year, the filter strip will be reseeded to maintain a dense growth of vegetation — Stable groundcover will be maintained in the drainage area to reduce the sediment load to the vegetation. — Two to three times a year, grass filter strips will be mowed and the clippings harvested to promote the growth of thick vegetation with optimum pollutant removal efficiency. Turf grass should not be cut shorter than 3 to 5 inches and may be allowed to grow as tall as 12 inches depending on aesthetic requirements (NIPC, 1993). Forested filter strips do not require this type of maintenance. — Once a year, the soil will be aerated if necessary. — Once a year, soil pH will be tested and lime will be added if necessary. After the filter strip is established, it will be inspected quarterly and within 24 hours after every storm event greater than 1.0 inch (or 1.5 inches if in a Coastal County). Records of inspection and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows. Any problems that are found shall be repaired immediately. BMP element: Potentialproblem: How I will remediate theproblem: The entire filter strip Trash/debris is present.

When the design depth reads 3 006'/N feet in the pretreatment unit, the sediment shall be removed from both the pretreatment unit and the infiltration basin. 5. if the Division determines that the system is failing, the system will immediately be repaired to original design specifications. If the system cannot be repaired to perform its design function, other stormwater control devices as allowed by NCAC 21-1 .1000 must be designed, approved and constructed.
