Silt Fence - ODOT Approved

A silt fence is a temporary sediment control device used on construction sites to protect water quality in nearby streams, rivers, lakes and water features. A typical fence consists of a piece of synthetic filter fabric (also called a geotextile) stretched between a series of wooden or metal stakes.

The stakes are installed on the downhill side of the fence, and the bottom edge of the fabric is trenched into the soil and backfilled on the uphill side. The fence is installed on a site before soil disturbance (earth moving) begins, down-slope from the disturbance area.*

Silt Fencing is one of the contractors’ foremost and common tools to control silt and soil infiltration on the construction site. Proper installation of a silt fence is key to its effectiveness.
