What is an important consideration when installing silt fence barriers?

When installing silt fence barriers, ensuring that the post spacing does not exceed 9 feet apart is crucial for maintaining the effectiveness of the barrier. Proper post spacing provides the necessary support for the fence and helps prevent it from sagging or failing under pressure from sediment or water flow. If the posts are spaced too far apart, the fabric may not remain taut, which can reduce its ability to filter sediment from flowing water, allowing pollutants to bypass the barrier.

This consideration helps ensure that the silt fence operates as intended by minimizing gaps that could lead to erosion and sedimentation issues. A well-installed silt fence, with appropriately spaced posts, is integral to controlling sediment during construction activities or land-disturbing activities. Proper installation and regular inspection are key to the long-term success of the silt fence in protecting water quality.
