Silt Fencing:

Silt fencing is a temporary barrier placed along the perimeter of a construction site. Silt fence does not serve to prevent erosion; rather, it traps soil or sediment from leaving the perimeter of the construction site. To be effective, silt fence must be constructed carefully and be in place before construction begins. Silt fences are primarily intended for trapping sediment from water erosion. They are less effective for wind erosion because they are not tall enough barriers.
