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 The covenants pertaining to stormwater may not be altered or rescinded without the express written consent of the State of North Carolina, Division of Energy, Mineral and Land Resources. 5. Alteration of the drainage as shown on the approved plan may not take place without the concurrence of the Division of Energy, Mineral and Land Resources. 6. The maximum allowable built -upon area per lot is square feet. *Note: If the BUA per lot varies, please substitute the following statement for the one above and provide a complete listing of the proposed BUA for each lot The maximum built -upon area per lot, in square feet, is as listed below: Lot # BUA Lot # BUA Lot # BUA Lot # BUA 1 40,537 2 35,405 3 17,441 4 42,305 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. 7. 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. 8. The owner of each lot, whose ownership is not retained by the permittee, is required to submit a separate stormwater permit application to the Division of Energy, Mineral and Land Resources and receive a permit prior to construction. 9. The project and 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.

The measuring device used to determine the sediment elevation shall be such that it will give an accurate depth reading and not readily penetrate into accumulated sediments. After the dry detention basin is established, it will be inspected quarterly. Inspection activities shall be performed as follows and any problems identified will be remediated immediately per the table below.
