What element is often integrated into designs for sediment control in construction sites?

Silt fences are an essential element frequently integrated into designs for sediment control at construction sites. They are specifically designed to capture sediment-laden runoff by allowing water to pass through while trapping sediment particles. Typically made of geotextile fabric, silt fences are installed around the perimeter of a construction site or in areas of disturbed soil. This helps prevent soil erosion and minimizes sediment transfer to nearby water bodies, which is crucial for protecting water quality and aquatic habitats.

Their effectiveness is derived from their ability to rely on the natural processes of filtration and sedimentation. Silt fences help to control sediment movement during rainfall events or when water is directed across construction sites. Because of these characteristics, they have become a standard practice in erosion and sediment control plans across various construction projects.
