When Is Super Silt Fence Required?
Super silt fence is typically called for where standard fence has already failed, or where slope, flow, or receiving water sensitivity exceeds what standard fence can reliably handle.

Repeated Standard Fence Failure
If standard silt fence has failed more than once at the same location despite correct installation, that's a strong signal the location needs more structural capacity than fabric and stakes alone can provide — which is exactly what the chain-link or welded-wire backing in super silt fence adds.
Long or Steep Slopes
Longer slopes concentrate more flow volume by the time runoff reaches the base, and steeper slopes increase flow velocity. Both increase the hydrostatic load on a sediment barrier beyond what standard fence is typically rated to handle.
Proximity to Sensitive Receiving Waters
Sites adjacent to wetlands, Outstanding Florida Waters, or other sensitive receiving waters often warrant — or may be required by the permitting authority to use — enhanced protection given the lower tolerance for any sediment discharge reaching these systems.
Frequently Asked Questions
Does super silt fence cost more than standard silt fence?
Generally yes, because of the added chain-link or welded-wire backing — but it's typically called for specifically where standard fence has already failed or where slope, flow, or receiving water sensitivity exceeds what standard fence can reliably handle.
Who decides whether super silt fence is required on a site?
Typically the project's SWPPP, BMP plan, or permitting authority specifies it for sensitive locations, but a qualified inspector or contractor can also recommend it where repeated standard fence failure signals the need for more structural capacity.
