Properly installed silt fence must be?

The assertion that all aspects regarding the installation and maintenance of a silt fence are important is a comprehensive view of the best practices in erosion control.

Firstly, regarding the proper installation technique, a silt fence should indeed be trenched into the ground. This practice, specifically the depth of about 8 inches, is critical to ensure that the base of the fence is secure and that sediment and water do not easily flow beneath it. Proper trenching also helps prevent undermining during heavy rain events.

Lapping the joints of the silt fence is another vital step. Effective lapping prevents sediment from escaping through any gaps that might form at the seams. When the fabric of the silt fence overlaps, it creates a barrier that improves the fence's overall efficiency by ensuring that sediment-laden water is effectively filtered through the fabric rather than flowing out.

Maintenance is also essential. A silt fence must be regularly inspected and maintained in order to perform adequately. This includes checking for tears or sagging in the fabric, ensuring that the fence remains securely anchored, and cleaning out sediment that might accumulate on the upstream side of the fence. A neglected silt fence can lead to failures in controlling sediment, thereby diminishing its intended effectiveness.

The combination of these factors
