INSTALLATION OF STRAW AND FABRIC FILTER BARRIERS FOR SEDIMENT CONTROL

Effective temporary erosion and sedimentation controls are critical during construction in the period between onset of earth-disturbing and final stabilizing by vegetation. Among the most common temporary controls used in Virginia and many other states are straw barriers, burlap filter barriers, and silt fences. Despite the large sums of money spent annually on these controls, high failure rates and low trapping efficiencies, particularly for straw barriers, have been reported. In an effort to improve field performance, experiments conducted in Virginia have led to the installation procedures reported in this paper. Procedures for inspection and maintenance of these controls are also described. Finally, it is concluded that the cost effectiveness of straw barriers has proved questionable in many cases; burlap filter barriers may well be an effective and inexpensive substitute for straw. /Authors/
