Approximately 9 0 acres will be graded to allow the expansion of the Burgaw Elementary School with paved parking and paved access The runoff from the site is estimated using the rational method 10-year design storm and rainfall data for the area Construction is scheduled to begin as soon as all permits and approvals are obtained EROSION CONTROL MEASURES The attached plans and specifications outline the requirements for erosion control measures Silt fencing will be provided along each side of the entrance dnve where stormwater would be expected to sheet flow from disturbed areas directly to adjacent property The detention pond will be used as a silt basin during construction and restored to its design contours prior to completion A gravel construction entrance will be constructed at the entrance Maintenance will be provided by the grading contractor and developer STORMWATER MANAGEMENT MEASURES The project site Is located in Pender County Land disturbing on the site will exceed one acre, which requires the site to comply with the State Regulations The stormwater runoff from the development will be directed to the stormwater detention pond CONSTRUCTION SEQUENCE The Contractor will install the gravel construction entrance and silt fence prior to beginning any clearing and grading operations Additional silt fence will be installed when and if conditions warrant during construction The detention pond/silt basin will be constructed immediately after that portion of the site is cleared, and outlet structure with protection will be installed Disturbed areas will be landscaped or seeded upon completion 10/04/2005 TUE 16, 59 FAX 910 343 9604 Norris, Kuske, Tunstall 4004/009 It EROSION CONTROL NOTES AND MAINTENANCE PLAN Install erosion control measures before beginning construction or as soon thereafter as possible All erosion and sediment control practices will be checked for stability and operation following every runoff -producing rainfall but to no case less than once every week Any needed repairs will be made immediately to maintain all practices as designed 2 Maintain the gravel construction entrances in a condition to prevent mud or sediment from leaving the construction site The contractor shall inspect the construction entrances on a daily basis This will require periodic top dressing with additional No 4 stone Any objectionable materials spilled, washed, or tracked onto public roadways shall be removed immediately 3 Install erosion control measures around the drop inlets as shown on the plans to trap silt during construction Inspect the erosion control around the inlets after each rain and make repairs immediately Remove sediment when it becomes 0 50 deep to provide adequate storage volume for subsequent rains When the contributing drainage area has been adequately stabilized, remove all materials and any unstable soil and either salvage or dispose of it properly Bring the disturbed area to proper grade and appropriately stabilize all bare areas around the drop inlets 4 Sediment will be removed from behind the silt fence when it becomes 0 5 feet deep at the fence The sediment fence will be repaired as necessary to maintain a barner Silt fence stakes shall be spaced 6 feet apart unless a wire backing is used with 8 foot stake spacing 5 Inspect temporary sediment traps 1 check dams after each period of significant rainfall Remove sediment and restore the trap to its original dimensions when the sediment has accumulated to one-half the design depth of the trap Place the sediment that is removed in the designated disposal area and replace the contaminated part of the gravel facing Check the structure for damage from erosion or piping Periodically check the depth of the spillway to ensure it is a minimum of 1 5 ft below the low point of the embankment Immediately fill any settlement of the embankment to slightly above design grade Any nprap displaced from the spillway must be replaced immediately After all sediment - producing areas have been permanently stabilized, remove the structure and all unstable sediment Smooth the area to blend with the adjoining areas and stabilize properly 6 No cut or fill slopes shall exceed a side slope of 1 vertical to 3 horizontal unless otherwise specified on the plan All slopes shall be seeded and stabilized within 15 days 10/04/2005 TUE 16,59 FAX 910 343 9604 Norris, Kuske, Tunstall 005/009 i 7 The stormwater ponds will act as sediment basins and will be cleaned out when the level of sediment reaches 2 0 ft below the top of the riser Gravel will be cleaned or replaced when the sediment pool no longer drains properly 8 All disturbed areas shall be seeded within 15 days of disturbance All seeded areas will be fertilized, reseeded as necessary and mulched according to specifications in the vegetative plan to maintain a vigorous, dense vegetative cover 9 More stringent measures shall be used to halt erosion if those shown on this
