DEFINITION

          A silt fence is a temporary sediment barrier made of woven, synthetic filtration fabric supported by either wood or steel posts.  

  

PURPOSE

The purpose of silt fence is to prevent the flow of sediment from leaving the desired site and entering natural drainage ways or storm drainage systems by slowing storm water runoff and causing the deposition of sediment at the structure.  Silt fencing encourages sheet flow and reduces the potential of developing ruts and gullies.

  

CONDITIONS

          Silt fence should be installed where sheet flow runoff can be stored behind the barrier without damaging the barrier or the submerged area behind the barrier. 

  

CONSTRUCTION

          A silt fence should be constructed on slopes greater than 7%, with the fence being impounded to a depth of at least 12 inches or more. Steel or wooden posts shoud be driven in to the ground to a depth of  at least 16 inches and placed no further apart than 8 feet.
