Silt Fence Maintenance
Silt Fence Installation & Inspection Schedule
Installation of a silt fence will typically involve a procedure of digging a trench and securing the barrier into position. Standard silt fencing will feature an overall height of three feet (3') to accommodate various sediment build up and water flows. Typical installation procedure for the silt fence is as follows:
- If stakes are not pre-attached, they should be placed accordingly to secure the barrier into position. Typical spacing for the stakes should not exceed 10 feet.
- Trenches should be excavated. Trenches should be sized about 4" wide and 4" deep. They should go along the line of posts and upslope from the barrier.
- Install the fabric along the barrier. Fabric will typically feature a 100' length. Fabric should extend the entire 100 feet. If areas feature a length longer than this, fabric should be overlapped to prevent any spacing.
Silt Fence Maintenance and Inspection
As a general guideline, the Silt Fence should be inspected frequently to ensure that it is operating correctly. In addition, you will also want to inspect your silt fence after each rainfall event. Due to the increased sediment and materials that can flow during storms, it is always best to inspect your site after every rainfall event to make sure all of your BMPs are still working properly.
What to Look for when Maintaining your Silt Fence
When you are inspecting your silt fence, there are a couple of problems and potential hazards that you should look for during inspection. These include:
- Gaps & Tears: If you find any gaps or tears in your fabric material, you should replace and/or repair the fabric immediately to ensure that your fence remains in top condition.
- High Sediment Accumulation: In addition, you will also want to look for high sediment accumulation along your fence. When the sediment along your fence reaches 1/3rd to 1/4th the height of your fence, it should be removed.
- Strains: Along with sediment, you will also want to check for strains located anywhere along the fence. If you do see the fence straining in any spot, you will want to remove sediment from that portion of the fence as well.
Accumulated sediment should also be removed when the silt fence itself is taken down and removed. Learn More
