The stormwater management system consists of a detention pond and an infiltration system. The detention pond, located in the southwest corner, shall serve 14.34 acres including Phase II (5 acres), future development area to the west of Phase II, and an existing off -site area. The infiltration systems shall serve part of the entrance road to Phase II (Kure Dunes Lane), and Lots 31, 32, and 33. The systems are located within the street right of way, in a public utility easement adjacent to U.S. 421 and drainage easement on Lots 31, 32, and 33. SECTION 2: OPERATING PERSONNEL RESPONSIBILITIES A. The Owner of the subdivision is a partnership, Kure Beach Associates, P. O. Box 179, Wilmington, NC. The local contact person is Joseph C. Hearne, (919) 458-4046. B. Kure Beach Associates shall construct the stormwater facilities and when complete turn over to the Town of Kure Beach to own and maintain. The Town contact person shall be Mayor J. E. Foster, II, Town of Kure Beach, P. O. Box 3, Kure Beach, NC 28449, telephone (919) 458-8216. 1 SECTION 3: MANAGEMENT RESPONSIBILITIES It is believed that management of the facilities will require only that it be included among other facilities requiring periodic verification from maintenance personnel reports and repair requirements and cost. SECTION 4: DESCRIPTION OF SYSTEM COMPONENTS A. All piping in improved areas is underground. Pipes have been sized to accommodate that runoff from a 10-year frequency storm. This is a standard of design which has been found to be economically feasible for the sizing of drainage pipelines in eastern North Carolina. Pipelines are graded so as to maintain a velocity of at least 2 feet per second and not exceed 5 feet per second. This will assure against deposits in the pipe system and yet not cause intense transport of particulate and suspended solids in the flows. B. Rainfalls of greater intensities or longer duration will not normally exceed the capacity of the system as such flows will increase the hydraulic gradient of the system, resulting in increased velocity and capacity. Care has been taken to avoid flooding in the system; however, short-term ponding in the low areas of the streets may occur during extremely heavy rains such as accompany tropical storms. This should also deter flooding of the system. C. The infiltration system has been designed in accordance with criteria set out in DEHNR Division of Environmental Management Regulation Section 1000, "Stormwater Runoff Disposal'. Details are set out on the plans. The systems will store the runoff from a one -inch (1") rainfall and infiltrate the stormwater within five days. Overflows are provided to pass storms in excess of one inch. D. The detention pond system has been designed in accordance with criteria set out in DEHNR Division of Environmental Management Regulation 2 Section 1000, "Stormwater Runoff Disposal'. Details are set out on the plans. The system will store the runoff from a one -inch rainfall and release the stormwater in not less than two days, and not more than 5 days. An overflow is provided to pass storms in excess of one inch. SECTION 5: SURVEILLANCE AND INSPECTIONS A. It is suggested that a visual inspection be made monthly of the surface areas of the system to detect any indications of blockages or flooding at inlets, manholes, or erosion or damage to swales, ponds, vegetative filters and outlet pipes. A simpler inspection should be made following heavy rainfall and storm events. B. A suggested semiannual inspection should be made, removing covers of all structures, cleaning out debris or deposits from the structures. Visual lamping of the pipelines should be made to detect any obstruction or damage to the lines. Ground slopes should be checked and repaired where necessary. C. Additional monitoring needs may be required by the Division of Environmental Management in the future. These requirements will be incorporated into the current maintenance plan. D. A report should be prepared in simple form and maintained in the proper file for all such inspections and maintenance actions. Copies should be sent to Management as information. SECTION 6: ACCIDENTAL SPILLS OR OVERWASH OF POLLUTED AREAS A. In the event of an accidental spill or overwash of an area containing hazardous material, the event should be immediately reported to Rick Shiver, Regional Supervisor, Division of Environmental Management, 127 Cardinal Drive Extension, Wilmington, N. C. 28405-3845 (Telephone 395-3900). 3 r. B. Immediate action by the Town of Kure Beach personnel should be taken to contain the spill or overwash, if possible. Corrective actions should be taken with the advice of the Regional Supervisor or other designated official having authority in such matters. SECTION 7: MAINTENANCE OF FACIIdTIES A. Pipelines should not normally require cleaning. If required, normal pipe cleaning equipment operating from structural openings should be used. B. Inlets, catch basins and manholes should be cleaned by direct removal of obstructions and debris through the top opening. C. The infiltration system swales and ditches located along U.S. 421 will require periodic cleaning by removal of sediment deposits and eroded material. The use of hand labor and fine grading equipment such as Gradall type units is suggested. The material should be trucked to an approved site for disposal. D. The pond system should be checked periodically for siltation, algae, or weed growth and accumulations of oil and grease. When 0.5 feet of silt accumulates, maintenance should be accomplished to remove the material. When algae or weed growth exceeds 25 percent of the normal water surface area, the algae and/or weed growth should be removed and disposed of properly. When oil or grease is visible, an absorbent material shall be used to remove these materials. E. Where maintenance problems appear to affect the successful operation of the facilities, assistance should be sought from the Designers or competent sources. M t SECTIONS: SYSTEM CERTIFICATION The Owner will make the necessary arrangements to be able to provide a statement from a North Carolina Professional Engineer that the system was constructed in accordance with the approved plans.
