Installation of Straw Barriers and Silt Fences

Report No: 77-R18

Published in 1976

About the report:

The most common types of temporary sediment control structures used by the Virginia Department of Highways and Transportation are straw barriers and silt fences. Based on observations made in Virginia and other parts of the nation, filter barriers have not been as effective as many users had hoped they would be. Different researchers have found that the sediment trapping efficiency of straw barriers has generally ranged from 0 to 20 percent. The reasons for the low trapping efficiencies and high failure rates of straw barriers are described. The proper installation procedures for straw barriers in ditch lines where flows not over 1 cfs are expected are stressed. The proper installation of silt fences for critical areas where siltation control is needed is also described.
