Position the posts on the downhill side of the barrier and drive the post 1.5 feet into the ground. 3. Lay the bottom 6" of the fabric in the trench to prevent undermining and backfill. 4. Inspect the silt fence at least once a week (preferably twice) and after rainfall events of 0.5" or greater. 5. Remove sediment when deposits reach approximately 1/2 the height of the fence. Sediment shall be deposited in an . area which is not regulated by the Inland Wetlands Commission. 6. Replace or repair within 24–hours of observed failure. Failure may include: –Overtopping, undercutting or bypassed by runoff water. –Fence has been moved or knocked over. –The geotextile has decomposed or has been damaged. 155, 86' S83•V 14 EXISITNG WELL N/F WENDY B.
