Silt Fence Used at Subdivision Site
A silt fence is made of posts and absorbent fabric to protect the watershed and infrastructure by forcing runoff to stay in its place. You've probably considered many things for your new home such as the roof, and landscaping, as well as the pros and cons of your driveway. All these projects are important but have you ever considered a silt fence or even know what it is? If not, it's time you take a closer look and learn why a silt fence is a must when building a new home.
Most jurisdictions now require silt fences at all construction sites. Without them, you could end up with a clogged-up sewer let alone messy sediment pouring into the street. If you or your contractor overlook a silt fence, you could face several fines and be surrounded by very angry neighbors.
A silt fence is nothing like your standard fence. It's a temporary barrier used by construction sites for erosion control. According to the Environmental Protection Agency, it's to hold the soil in disrupted areas. Silt fences will keep the soil you are digging up and moving it around during the home-building process and winding up on roads, in rivers, lakes, streams, ponds, and estuaries. An estuary is a semi-closed coastal body of water with one or more rivers or streams flowing into it and has a connection to an ocean or the sea.
Chances are, whether you realize it or not, you have probably seen stilt fences in residential and commercial construction sites. These fences are not something you would leave standing after the construction is completed. The porous fabric, known as geotextile, is held in place with posts. It's critical that these fences are designed and placed correctly by digging, measuring, and trenching to get them right.
Even though there are several different kinds of silt fences, only a very few are used on home construction sites. If installed properly, they are sturdy and should keep sediments away from local roads and/or watersheds.
Common staked silt fences are usually the ones you would install. A Type A fence requires 36-inch fabric and a minimum post length of 4-inches. Type B requires 22-inch fabric and a minimum post length of 3-inches. The design is basically the same and both types feature wooden or PVC posts.
These fences are also known as a wire-back silt fences. According to Dyersburg, Tennessee’s erosion control handbook, Type Cs are constructed with 40-inch metal or steel posts and the installation of 36-inch fabric. These fences are usually recommended for homes being built near creeks, streams, and ponds as the metal posts offer extra reinforcement.
