What is a Silt Fence?

A silt fence is a temporary barrier of fabric staked along the low side of a disturbed site, trapping soil runoff before it leaves the property. With ArcSite, you can drop this detail onto your site plan and mark exactly where the fence runs.

FAQ

What's the difference between the two fabric options?

Priority 1/BSRF fabric (green band) uses wood posts every 4' max, and Priority 2 fabric (black band) allows posts up to 6' apart. Both use 36" fabric with 2' showing above grade.

Can I add this detail to a full site plan?

Yes! You can place this detail on a larger site drawing in ArcSite and trace the fence line around the disturbed area.

Does ArcSite work for site plans, or just house-scale drawings?

Both. You can draw a full site plan in ArcSite and export a clean PDF to send to an inspector or general contractor.
