Product Description:

Silt fence is a temporary sediment barrier made of porous fabric. It is held up by wooden or metal posts driven into the ground and it is inexpensive and relatively easy to remove. The fabric ponds sediment-laden stormwater runoff, causing sediment to be retained by the settling processes. A single 100 foot run of silt fence may hold 50 tons of sediment in place. Most construction sites today do have silt fences but many do not work effectively because they are not well designed, installed, or maintained.

The purpose of a silt fence is to retain the soil on disturbed land, such as a construction site, until the activities disturbing the land are sufficiently completed to allow re-vegetation and permanent soil stabilization to begin. Keeping the soil on a construction site, rather than letting it be washed off into natural water bodies (e.g., streams, rivers, ponds, lakes, estuaries) prevents the degradation of aquatic habitats and siltation of harbor channels. Also, not letting soil wash off onto roads, which readily transports it to storm sewers, avoids having sewers clogged with sediment. The cost of installing silt fences on a watershed’s construction sites is considerably less than the costs associated with losing aquatic species, dredging navigation channels, and cleaning sediment out of municipal storm sewers.


Inspection & Maintenance:

Silt fences should be inspected routinely and after runoff events to determine whether they need maintenance because they are full or damaged by construction equipment. The EPA guidelines recommends removing sediment deposits from behind the fence when they reach half the height of the fence or installing a second fence. However, there are several problems associated with cleaning out silt fences. Once the fabric is clogged with sediment, it can no longer drain slowly and function as originally designed. The result is normally a low volume sediment basin because the cleaning process doesn’t unclog the fabric. The soil is normally very wet behind a silt fence, inhibiting the use of equipment needed to move it. A back hoe is commonly used, but, if the sediment is removed, what is to be done with it during construction? Another solution is to leave the sediment in place where it is stable and build a new silt fence above or below it to collect additional sediment. The proper maintenance may be site specific, e.g. small construction sites might not have sufficient space for another silt fence. Adequate access to the sediment control devices should be provided so inspections and maintenance can be performed.
