#47 Silt Fence for Sediment Runoff Control

Description:  This photo shows a silt fence in the process of being installed around the perimeter of a construction site.  The purpose of a silt fence is to contain the fine silty material that is often agitated during construction activities and keep it from washing away. By keeping the silty material on site it effectively protects adjacent storm sewers and surface waters from contamination.  A silt fence is composed of a synthetic fabric and secured in place by wooden stakes.  This is a common method of erosion control used on a variety of projects.

    A silt fence is typically buried a few inches below the soil surface to stop the particles from flowing under it in a rain event.
