Use drainage ditch installation for low flow conditions only when specified on Erosion Control Plan.

Alternate preassembled silt fence options will be allowed as long as specified dimensions are satisfied. Follow manufacturer's recommendations for installation procedures.

All types must ensure silt fence remains attached to, and does not slide down, supporting posts.

Install silt fence along ground contours. Curve ends of silt fence upgrade to prevent water from running around the ends.
