What is the maximum spacing for posts when installing a silt fence?

The maximum spacing for posts when installing a silt fence is 6 feet. This guideline is important because it ensures the structural integrity and effectiveness of the silt fence in preventing sediment runoff. The posts act as a barrier to support the fabric of the silt fence and maintain its height, which is critical for intercepting sediment-laden water. If posts are spaced too far apart, the fence may sag or fail, allowing sediment to pass through or around the barrier, thereby reducing its overall efficiency in controlling erosion and sediment movement around construction sites. Proper installation with adherence to this spacing guideline helps maintain compliance with erosion control regulations and best management practices.
