Silt Fence

A silt fence, or filter fence, is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and bays from sediment (loose soil) in stormwater runoff. Silt fences are perimeter controls, typically used in combination with (properly designed) sediment basins and sediment traps, as well as erosion controls, which are designed to retain sediment in place where soil is being disturbed by construction processes.
