Alternatives to Silt Fence for Temporary Sediment Control at Highway Construction Sites: Guidelines for TxDOT (1737-S)

Since the implementing of the NPDES, TxDOT has spent an average of approximately $4.5 million on the installation and maintenance of silt fence. This project identified three promising alternatives to the use of silt fence for temporary sediment control on construction sites. The report provides an analysis of the cost effectiveness of the alternatives compared to silt fence and makes several recommendations for selecting an appropriate alternative to silt fence. Based on the research, the report recommends that the use of silt filter fence as an in-channel silt dam should be discontinued in favor of a more suitable option. The report appendix provides suggested special specifications and alternative materials.
