Key takeaways
- Silt fences, vegetative buffer strips or equal controls are required on all down-slope boundaries of the construction area, at any site size.
- Side-slope boundaries get them where appropriate.
- Clear sediment before it reaches 50% of the fence height.
- Repair before the next rain if feasible. Replace a run-over fence immediately.
What does the permit require?
Silt fences, vegetative buffer strips or equal sediment controls are required at a minimum for all down-slope boundaries of the construction area, at any site size. They are also required for the side-slope boundaries deemed appropriate.
Choose, install and maintain controls using good engineering practices and the manufacturer's or designer's specifications.
Install controls before work that disturbs soil begins.
How do I keep it working?
| Situation | Rule |
|---|---|
| Fence damaged or failing | Repair before the next rain if feasible |
| Fence run over or disabled | Replace immediately on discovery |
| Sediment builds up | Remove it before it reaches 50% of the fence height |
| Sediment escaped past the fence | Remove it before the next rain if feasible |
How does an inspection check it?
An inspection looks at stormwater controls and the places stormwater flows, and at discharge points. Write what needs maintenance in the report.
See inspection frequency.
When is a sediment basin needed instead?
Where 10 or more acres drain to one point at one time, the permit calls for a sediment basin where feasible. ReadySWPPP does not build plans for that case.
Do cities add rules?
Yes, local specifications can be stricter, and the permit allows it. For your city, see the city guides.
FAQ
Is silt fence required on every Texas site?
Yes, at any site size silt fence, vegetative buffer strips or an equal control is the minimum on down-slope boundaries.
How full can a silt fence get?
Remove sediment before it reaches 50% of the fence's height.
What about the construction exit?
Your site map shows where vehicles exit onto paved roads, and inspections check vehicle exits for tracking.
