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 shall be
dressed to conform with the existing grade, prepared, and seeded with
appropriate seed mix, as directed by the engineer.
4. Removal of the silt fence- Silt fences shall be removed when they have
served their useful purpose, but not before the upward sloping area has been
permanently stabilized.
