For proposed paved surface areas, the contractor may remove necessary silt fencing to construct roadway, while maintaining adequate erosion control in adjacent areas. 5. Sufficient topsoil shall be stockpiled to allow for the replacement of 4" topsoil for disturbed areas to be re -vegetated. 6. The contractor shall schedule site grading, utility installation and site construction so that the general site can be mulched and sodded or re -seeded as soon as possible soon after disturbance. Areas that will not be subject to construction traffic shall be seed and mulched or sodded within 72 hours of final grading. EROSION CONTROL MAINTENANCE SCHEDULE 1. Erosion control measures shall be inspected by the contractor's representative and maintained by the contractor every Friday and within 24 hours after any rainfall event larger than 1/2" until the project is completed. Maintenance requirements are as follows: silt fence - 1/3 height of fence or damaged, remove sediment and/or repair fence within 24 hours; rock entrance - refresh as necessary to conform to detail; inlet protection inserts - remove sediment after each rain event, clean or replace filter when clogged; surface water - drain and stabilize, within 72 hours of discovery; street sweeping - remove all sediment tracked onto paved surfaces within 24 hours or as directed by City Engineer. 2. Replacement - Fabric shall be replaced promptly when it decomposes or becomes ineffective before the barrier is no longer necessary. 3. Any sediment remaining in place after silt fence is no longer required N shall be dressed to conform with the existing grade, prepared, and seeded with appropriate seed mix, as directed by the engineer. O �- 4. Removal of the silt fence- Silt fences shall be removed when they m have served their useful purpose, but not before the upward sloping 3 area has been permanently stabilized.
