Erosion Fence

Driving past construction sites, we have all seen these short, black fences winding around the work area. They are not very high so they are surely not there to keep unauthorized personnel out.  They may have no use for security purpose with people but they are a security measure when it comes to dirt. They are called erosion control fences and they are mandated by the Environmental Protection Agency (EPA). A contractor is required to retain all the dirt on site and prevent it from draining off-site into creeks and streets. The very nature of site construction involves clearing away the vegetation that held the dirt in place. With that buffer gone you must replace that protection. Wherever you have slopes that would facilitate sediment leaving the property you are required to construct an erosion control fence, also called a silt fence.

These fences are made of vinyl fabric and attached to post in 10-foot intervals. (DeWitt SILTFENCE36, 3’ x 100’) Installing an erosion control fence is quite simple. Dig a trench about 4 inches wide and 6 inches deep. Place the fence in the trench and bury at least 6 inches of the fence. That’s it …for now. It is important to maintain the fence. Heavy rains and strong winds can damage the fence and allow dirt to erode so keep an eye on it and repair or replace as necessary.
