NC Engineered/Grass Swale This section of inspection and maintenance agreement pertains to the extended detention wetlands and wet ponds at the following locations: Focus Area #7 - Residential Area#3 Engineered/Grass Swale Maintenance activities shall be performed as follows: General Maintenance (in addition to significant runoff producing rainfall events) 1. Vegetation & Repair - The swale has a ground cover of fescue, which if properly maintained will prevent erosion and provide an easy surface for inspection. Grass should be fertilized every October and April. · Re-Seeding (when needed) - annually re-seeding may be required to establish grass on areas where seed did not take or has been destroyed. Before seeding, fertilizer (12-12-12) should be applied at a minimum rate of 12 to 15 pounds per 1,000 SF. The seed should be evenly sewn at a rate of three pounds per 1,000 SF. The seed should be covered with soil to the depth of approximately Y4". Immediately following the planting, the area should be mulched with straw. 2. Establishment Period - During the establishment period, check grass-lined channels after every rainfall. After grass is established, periodically check the channel; check it after every heavy rainfall event. Immediately make repairs. It is particularly important to check the channel outlet and all road crossings for bank stability and evidence of piping or scour holes. Keep the grass in a healthy, vigorous condition at all times, since it is the primary erosion protection for the channel. 3. Mowing - grass mowing, brush cutting and removal of weed vegetation will be necessary for the proper maintenance of the swale and should be mowed at a minimum of twice annually. Acceptable methods include the use of weed whips or power brush cutters and mowers. 4. Erosion - Erosion occurs when the water concentrates causing failure of the vegetation or when vegetation dies and sets up the environment for rill erosion and eventually gullies from the stormwater runoff. The swale should be inspected for these areas. Proper care of vegetative areas that develop erosion is required to prevent more serious damage to the swale. Rills and gullies should be filled with suitable soil compacted and then seeded. Methods described in Section I-A, on vegetation, should be used to properly establish the grass surface. Where eroded areas are detected, the cause of the erosion should be addressed to prevent a continued maintenance problem. 5. Remove all significant sediment accumulation to maintain the designed carrying capacity.

Maintenance activities shall be performed as follows: 1. After every significant runoff producing rainfall event and at least monthly: Page 2 of 2 a. Inspect the wetland 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 wetland 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 wetland 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 feet in the main pond, the sediment shall be removed. If the elevations of the marsh areas exceed the permanent pool elevation, the sediment should be removed to design levels. This shall be performed by removing the upper 6 inches of soil and stockpiling it. Then the marsh area shall be excavated six inches below design elevations. Afterwards the stockpiled soil should be spread over the marsh surface. The soil should not be stockpiled for more than two weeks.] When the permanent pool depth reads removed. feet in the forebay and micro-pool, the sediment shall be BASIN DIAGRAM (fill in the blanks) \l Permanent Pool Elevation Bottom Elevation 75% Sediment Removal Elevation FOREBAY MAIN POND 5. Remove cattails and other indigenous wetland plants when they cover 50% of the basin surface. These plants shall be encouraged to grow along the vegetated shelf and forebay berm. Wetland planting densities in the marsh areas should be maintained by replanting bare areas as needed. Wetland plants should be encouraged to grow in the marsh areas. 6. Mowing - grass mowing, brush cutting and removal of weed vegetation will be necessary for the proper maintenance of the wetland/pond and should be mowed at a minimum of four times a year. Acceptable methods include the use of weed whips or power brush cutters and mowers. 7. If the basin must be drained for an emergency or to perform maintenance, the flushing of sediment through the emergency drain shall be minimized to the maximum extent practical. 8. All components of the wet [wetland] detention basin system shall be maintained in good working order. 9. Level spreaders or other structures that provide diffuse flow shall be maintained every six months. All accumulated sediment and debris shall be removed from the structure, and a level elevation shall be maintained across the entire flow spreading structure. Any down gradient erosion must be repaired and/or replanted as necessary. j ~ Page 3 of 3 - ~ Extended Detention Wetland and Wet Pond - Clean Out Elevations Facility 10 Forebay Forebay Bottom Permanent Pool Elev.

Maintenance of Earthen Containment Embankment A. The earthen embankment shall at all times maintain a thick, healthy grass cover which is free of brush. This type of cover, if properly maintained, will prevent erosion of the embankment and provide an easy surface for inspection. Grass shall be properly fertilized every October and April (or as required) to ensure that a substantial stand of grass is continuously present. B. Grass mowing, brush cutting, and removal of weed vegetation will be necessary to the proper maintenance of the embankment. The embankment slopes and emergency spillway area if applicable shall be mowed when the grass exceeds eight inches (8") in height. Acceptable methods include use of mowers, power brush cutters and weed whips. C. Re-seeding: The embankment shall be periodically (at least once a year) limed, fertilized and shall be re- seeded each fall. Consult the North Carolina State Cooperative Extension Services or the Soil and Water Conservation District Office to determine precise lime and fertilizer requirements. D. Trees and other unwanted woody vegetation shall not be allowed to grow on the earthen embankment. Any vegetation which inhibits proper operation of the facility shall be removed. E. All erosion gullies which form between maintenance operations shall be backfilled with topsoil material, re-seeded and mulched properly until new vegetation is established. This is necessary to ensure that such areas do not evolve into more serious damage situations. F. All bare areas and pathways on the embankment shall, continuously as they occur, be properly re- seeded and mulched to prevent further erosion. G. During the regular quarterly inspection, the entire embankment shall also be inspected for cracks or sloughing. Short, isolated cracks are usually not significant and can be repaired like erosion gullies; however, larger cracks (wider than 1/4 inch), well defined, longer cracks, or large sloughed areas indicate a serious problem. Should any such signs occur or be noticed, an experienced engineer must be consulted and retained in order to ascertain cause of damage and prepare repair plans. Such repairs shall be carried out immediately. 2. Maintenance of the Flow Control Structure: Page 5 of 5 , ., A. The Flow Control Structure is a specially designed inlet structure. All concrete and/or block portions of the structure shall be inspected during the regular quarterly inspection for signs of cracking or deterioration. Cracks shall be considered significant if they exceed 1/8" in width. Minor needed repairs shall be made immediately upon notice of damage, Once every six months, the interior of the structure and all inlet and outlet conduits shall be inspected for signs of damage, leakage and/or misalignment. Should any such signs occur or significant cracking and/or deterioration be noticed, an experienced engineer must be consulted and retained in order to ascertain cause of damage and prepare repair plans. Such repairs shall be carried out immediately. This structure and all inlet/outlet conduits shall be kept clear of debris and shall not be allowed to serve as permanent shelter for animals which may introduce such debris. B. The weir crest areas shall be kept free of debris. 3. Maintenance of Inflow and Outflow Points: A. All riprap armoring shall be kept clear of debris and unwanted vegetation. Riprap material shall be replenished as needed to control erosion. 4. Maintenance of Planting Soil Area: A. On a monthly basis, inspect and repair any eroded areas. Keep area clear of accumulated debris. B. Once per year test for pH. Add limestone as required to maintain a pH range between 5.5 - 6.5 at least once per year. C. Replenish mulch as specified in project manual no less than once every six months. 5. Plant Materials: A. Remove and replace all dead and diseased vegetation considered beyond treatment. Perform this task twice per year between March 15 and April 30, and October 1 and November 30. B. Treat all diseased trees and shrubs as needed. Replace dead or nonrecoverable diseased plants with like kind as near to size as possible. C. Adequately water all replacement vegetation and plants as required for not less than fourteen consecutive days after planting. D. Replace or repair all support stakes and associated wiring as needed.

We have attached a design spreadsheet, a DWQ worksheet, a stormwater/grading plan, and a signed and notarized maintenance and inspection agreement. Per our November 7, 2005 telephone conversation, a review fee has not been included with this submittal because this request follows up on the previous Ford's Colony (overall development) 401 permit application that required a review fee. The conceptual design of this pond was reviewed and approved by DWQ as part of the overall development plan. A copy of this approval letter is attached with this letter for your reference. The following is a summary for the wet pond design parameters: Drainage Area - 48.13 acres. Impervious Area - 14.87 acres. Impervious % - 30.9 Minimum Required Surface Area - 28,513 square feet. Minimum Required Reservoir Volume (permanent pool) - 87,279 cubic feet. Minimum Required Forebay Volume - 16,915 cubic feet (20% of minimum required reservoir volume). Provided (proposed) Surface Area - 28,586 square feet. Provided (proposed) Reservoir Volume (permanent pool) - 87,503 cubic feet. Provided (proposed) Forebay Volume - 16,958 cubic feet. WK Dickson is requesting a waiver for the required forebay volume at the Sound Pond in Focus Area #8. We feel that the proposed Sound Pond should exceed minimum design standards for a wet pond. The subject forebay has been designed to be approximately 20% of the minimum reservoir volume needed to meet Division of Water Quality (DWQ) requirements for a wet pond. The minimum reservoir volume was determined based on the percent imperviousness of the upstream drainage area 3101 John HUlllllhrips Wynd Raleigh, NC 27612 Tel. 919.782,0495 Fax 919.782.9672 www,wkdickson,colll North Carolina.
