The project construction also includes: (1)Installation of erosion control measures, (2) Grading, (3)Utility installation, (4)Building construction, (5)Paving and(6)Re-stabilization of all disturbed areas. SITE DATA: The 11.49 acre(9.63 acres disturbed) site is located on New Airport Road and Airport Park Road in Fletcher,NC. The pre-developed site contains mostly impervious area in the vicinity of the Sheetz store and mostly forested area in the new parking lot area. The site has flat to moderate slopes. The site drains to the southeast to an existing creek and west to an existing pond near New Airport Road.Properties adjacent to the site are commercial to the northeast and industrial to the east,New Airport Road to the west,Airport Park Road to the north,and Fanning Bridge Road to the south. SOILS: According to the web soil survey for Buncombe County,North Carolina the soil classification of the site is Clifton sandy loam(CsC),Urban land(UhE), and Hayesville loam(HyC). EROSION& SEDIMENT CONTROL PRACTICES 1. Sediment Fence-6.62: To be installed around on downgrade side perimeter of disturbed area and of stockpiles to intercept and detain sediment from sheet runoff of disturbed areas during construction and prevent it leaving the site, not for concentrated flows. 2. Temporary Block& Gravel Inlet Protection-6.52: To be installed around all newly constructed and existing drainage inlets to intercept and detain sediment from disturbed areas during construction operations in order to prevent sediment from entering the storm pipe system. 3. Porous Baffles-6.65: Porous barriers installed inside temporary sediment basin to reduce velocity of runoff and allow settling of sediment before leaving the site. 4. Concrete Washout Container: To be installed near the construction entrance/exit to receive wash water from concrete trucks and concrete tools. The purpose of the container is to collect and retain concrete solids and concrete wash water for proper disposal. 5. Temporary Sediment Basin-6.61: To installed in the southern corner of the site to retain sediment on the construction site for most of the new parking lot, and prevent sedimentation in off-site streams, lakes, and drainageways. It will allow large amounts of sediment to settle out of construction runoff before it enters the storm pipe system. 6. Temporary/Permanent Seeding-6.10/6.11: To stabilize denuded areas during grading operations and after land disturbance is completed. 7. Temporary Diversion-6.20: To be installed along east edge of disturbed area to direct runoff into the sediment basin.
