1. An approved geotextile should be attached to the upstream side of the post and any backing.
2. Construct the silt fence from a continuous roll of geotextile if possible. When joints are necessary, it is preferred that the material be overlapped to the next post.
3. The bottom edge of the geotextile should be buried at least 6 inches deep in a vertical slot or trench, with the soil pressed firmly against the embedded geotextile. (Machine-slice methods are also acceptable.)
4. Posts should be either 1.5-inch hardwood with a minimum length of 4 ft or 1.25 lb/linear ft steel with a minimum length of 5 ft.
5. Posts should be set in the ground at least 1.5 ft deep.
6. Post spacing depends on the site conditions, but 6-8 ft on center is a standard maximum.
7. Each post should be securely fastened to the geotextile and net backing by ties or staple suitable for such purpose.
8. Never attach silt fence to trees.

Maintenance

1. Inspect silt fences at least once a week and after each 1/2 inch rainfall within 24 hours. Make any required repairs immediately.
2. Should the fabric of a silt fence collapse, tear, decompose or otherwise become ineffective, replace it within 24 hours of discovery.
3. Remove silt deposits once they reach one-third the height of the silt fence to provide adequate storage volume for the next rain and to reduce pressure on the fence.
4. Remove all fencing materials and unstable sediment deposits and bring the area to grade and stabilize it after the contributing drainage area has been property stabilized.

Roadway Deposits

1. A temporary construction entrance should be constructed out of rock to clean vehicles' tires before they reach the roadway.
2. All materials tracked or otherwise deposited on roadways shall be cleaned at least daily.
3. All material, which is deposited on adjacent roadways as a result of a precipitation event, shall be removed, including the cleaning of storm sewers and drainage ditches, within 24 hours.
