Abstract
A silt fence structure and method of controlling erosion are disclosed. The silt fence structure includes a water permeable fence, an apron having first and second edges, the first edge providing a buried apron toe, the second edge attaching to the water permeable fence, and at least one flow barrier attached to the water permeable fence and to the apron so as to impede lateral runoff flow along the water permeable fence.
Claims19
A silt fence structure comprising:
- a water permeable fence;
- an apron having first and second edges, the first edge providing a buried upstream apron toe, the second edge attaching to the water permeable fence and providing a buried downstream apron toe;
- and
- at least one flow barrier attached to the water permeable fence and to the apron so as to impede lateral runoff flow along the water permeable fence.
A silt fence structure for controlling erosion on a sloped ground surface having an upstream direction and a downstream direction, the structure comprising:
- a water permeable fence providing a fence toe buried in the ground surface;
- a plurality of flow barriers;
- an apron having first and second edges, the first edge providing an upstream apron toe and the second edge providing a downsteam apron toe;
- and
- a plurality of fence posts, each with a first end buried in the ground surface and extending generally upward therefrom;
- wherein the apron is attached to the fence proximate the second edge of the apron and extends from the fence in the upstream direction, the fence is attached to the apron proximate the fence toe, and the upstream and downstream apron toes are buried in the ground surface;
- wherein each of the plurality of flow barriers is attached to the filter fence along a first edge of the flow barrier and attached to the apron along a second edge of the flow barrier;
- and
- wherein at least one of the plurality of fence posts attaches to the fence proximate a location connecting to at least one of the plurality of flow barriers.
A method of controlling erosion on a sloped soil surface having an upstream and a downstream direction, the method comprising:
- planting a plurality of fence posts into the soil;
- attaching a silt fence between the plurality of posts;
- providing an apron attached along the fence, the apron forming a downstream apron toe proximate the fence and extending overground therefrom in an upstream direction to form an upstream apron toe;
- burying the downstream and upstream apron toes in the soil;
- and
- attaching at least one flow barrier between the fence and the apron.
