Silt Fence Sediment Control in Alabama

In Alabama, silt fences are commonly used at construction sites as a temporary but potent means of controlling sediment. These fences act as boundary barriers, preventing sediment from entering and potentially contaminating adjacent bodies of water like seas, lakes, streams, and oceans, thus helping to maintain water quality. Silt fences also help prevent erosion, protecting the site’s landscape during construction.

To enhance the effectiveness of silt fences in managing sediment, Alabama’s construction projects incorporate additional methods. Techniques such as sediment basins and traps prove particularly useful in capturing soil disturbed during excavation and construction. This collected sediment can then be moved and reused elsewhere, aiding in the state’s efforts to conserve the environment.

Silt Fence Types

Standard Staked

Standard silt fence is strong and filters out many pollutants. It helps control erosion and water contamination during construction.

Type C Wire Back

Wire back Type C silt fence is mandatory when the construction site is located near ponds, lakes, or other bodies of water. Its features for added strength include hog wire back, steel posts, and a fabric consisting of woven geotextile.

Orange Safety

When visibility is a concern, an orange safety silt fence is recommended. The bright orange plastic mesh design is highly noticeable to warn passersby that the construction site is a danger zone.


Two types of DOT silt fence are CPOP and TYPE A. They contain polypropylene yarns of high strength with a backing of polypropylene mesh. Its sturdy design keeps the fence in a stable position. The materials guard against degradation, rotting, and ultraviolet damage.

CPOP - Includes hardwood stakes sized 2"x2". The centers are 4 feet tall. The CPOP can be used instead of the Wire Back silt.

TYPE A - Includes hardwood stakes sized 1 1/2” X 1 1/2. The centers are 6 feet tall.

The DOT Qualified Product List has a list of state-approved silt fence.

Tree Save

A boundary-marketing silt fence, Tree Save is bright orange for high visibility when the work zone is located in or around environmentally sensitive areas such as wetlands, wildlife habits, and others. The leno weave design also contains UV protection against deterioration.
