SUPER SILT FENCE

Definition

A temporary barrier of Geotextile Class F over chain link fence used to intercept sediment laden runoff from small drainage areas.

Purpose

To reduce runoff velocity and allow the deposition of transported sediment to occur.  Limits imposed by ultraviolet light stability of the fabric will dictate the maximum period that the silt fence may be used.

1.   Super silt fence provides a barrier that can collect and hold debris and soil, preventing the material from entering critical areas, streams, streets, etc.

2.   Super silt fence can be used where the installation of a dike would destroy sensitive areas, woods, wetlands, etc.

3.   Super silt fence should be placed as close to the contour as possible.  No section of silt fence should exceed a grade of 5% for a distance of more than 50 feet.
