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 Eng'neer. 2. Replacement - Fabr'c shall be replaced promptly when it decomposes or becomes ineffective before the barrier is no longer necessary. 3.
