FORM SWU-102 Rev 3.99 PAGE 2 OF 4 Maintenance activities shall be performed as follows: 1. After every significant runoff producing rainfall event and at least monthly: a. Inspect the wet detention basin system for sediment accumulation, erosion, trash accumulation, vegetated cover, and general condition. b. Check and clear the orifice of any obstructions such that drawdown of the temporary pool occurs within 2 to 5 days as designed. 2. Repair eroded areas immediately, re-seed as necessary to maintain good vegetative cover, mow vegetative cover to maintain a maximum height of six inches, and remove trash as needed. 3. Inspect and repair the collection system (i.e. catch basins, piping, swales, riprap, etc.) quarterly to maintain proper functioning. 4. Remove accumulated sediment from the wet detention basin system semi-annually or when depth is reduced to 75% of the original design depth(see diagram below). Removed sediment shall be disposed of in an appropriate manner and shall be handled in a manner that will not adversely impact water quality (i.e. stockpiling near a wet detention basin or stream, etc.). 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. When the permanent pool depth reads 5.25 feet in the main pond,the sediment shall be removed. When the permanent pool depth reads 5.25 feet in the forebay,the sediment shall be removed.

CURB OUTLET SYSTEM MAINTENANCE REQUIREMENTS 1. Mowing will be accomplished as needed according to the season. Grass height will not exceed six inches at any time. 2. Swales will be inspected monthly or after every runoff producing rainfall event for sediment build-up, erosion, and trash accumulation. 3. Accumulated sediment and trash will be removed as necessary. Swales will be reseeded or sodded following sediment removal. 4. Eroded areas of swales will be repaired and reseeded. Swales will be revegetated as needed and in a timely manner based on the monthly inspections. 5. Catch basins, curb cuts, velocity reduction devices and piping will be inspected monthly or after every significant runoff producing rainfall event. Trash and debris will be cleared away from grates, curb cuts, velocity reduction devices and piping. 6. Swales will not be altered,piped, or filled in without approval from NCDENR Division of Water Quality. I acknowledge and agree by my signature below that I am responsible for the performance of the six maintenance procedures listed above. I agree to notify DWQ of any problems with the system or prior to any changes to the system of responsible party. Print name and Title: Nathan D.

Deed restrictions and protective covenants are necessary to ensure that the development maintains a "built-upon" area consistent with the applicable regulation governing the density level. I, Nathan D. Benson acknowledge and affirm by my signature below, that I will cause the following deed restrictions and protective covenants to be recorded for San Rio—Phase 2A prior to the sale of any lot: 1. The following covenants are intended to ensure ongoing compliance with State Stormwater Management Permit Number SW8 070202, 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 plans may not take place without the concurrence of the Division of Water Quality. 6. The maximum built-upon area per lot is as follows: Onsite Buildin:s 3.24,606 Onsite Streets 310,915 Onsite Sidewalks 98,368 Other onsite Im.ervious 32,670 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. In the case of a lot within CAMA's regulated AEC, where the Division of Coastal Management calculates-a different maximum allowable built-upon area for that lot than is shown herein, the governing maximum built-upon area for that lot shall be the most restrictive of the two 8. This project proposes a curb outlet system. Each designated curb outlet swale shown on the approved plan must be maintained at a minimum of 100'long with 5:1 (H !' side slopes or flatter, have a longitudinal slope no steeper than 5%, carry the flow from a 10 year storm in a non-erosive manner, and maintain a dense vegetated cover. 9. Filling in or piping of any vegetative conveyances (ditches, swales, etc) associated with the development except for average driveway crossings, is strictly prohibited by any persons. 10. Each lot will maintain a 30'wide vegetated buffer between all impervious areas and surface waters. 11. All roof drains shall terminate at least 30'from the mean high water mark of surface waters. 12. Filling in, piping or altering any designated 5:1 curb outlet swale associated with the development is prohibited by any persons. 13. All stormwater runoff from the street sections within the low-density areas must drain into the permitted vegetated swales though the curb-outlet system. 14. All runoff from the high-density areas shall drain into the permitted system. This may be accomplished through providing roof drain gutters which drain to the street, grading the areas to drain toward the street, or grading perimeter swales and directing them into a component of the stormwater collection system. Areas that will naturally drain into the system are not required to provide these additional measures. 15. Built-upon area in excess of the permitted amount will require a permit mod f cation.
