In inspecting silt fence barriers, where should the stakes be placed?

• A. On the upstream side of the fabric
• B. On the downstream side of the fabric
• C. Equally on both sides
• D. Stakes are not required

Answer: (B)

The main idea here is how to secure a silt fence so it stays effective against flowing runoff. The fabric should be anchored with stakes on the downstream side. This placement helps keep the barrier tight against the soil as water moves downhill, resisting the tendency of the fabric to pull away or tear at the attachment points. With the stakes on the downstream edge, the barrier remains pressed into place where it’s most likely to be stressed by flow, so sediment is captured instead of bypassing the barrier. Placing stakes on the upstream side would make the barrier more prone to lifting or tearing under flow, and staking on both sides isn’t the standard practice. Stakes aren’t unnecessary for a silt fence.
