This Standard is intended to guide designers on the purpose, design, material selection, installation, and maintenance of a silt fence when used as a temporary sediment control barrier for sheet flow applications to minimize sediment transport from a disturbed area susceptible to erosion. 

Included in this package is the recorded webinar from January 20, 2021 discussing this standard. Upon completion of the webinar, you will receive 1 Professional Development Hour.

Developed by the IECA Standards and Practices Committee.

A Performance-Based Design and Installation Standard for Silt Fence
Open to view video.
Open to view video. Existing silt fence design guidance primarily relies on state design standards which were developed based on rules-of-thumb that lack scientific justification. Proper design and implementation of silt fence is critical and must consider site-specific factors such as: topography, precipitation, soil type, and other site parameters. This presentation will describe a silt fence sediment barrier design and installation standard developed through a comprehensive literature review of current state agency guidance and performance-based research. This study proposes a hydrologic design approach using local site conditions while accounting for detention volumes provided by silt fence barrier installations. In addition, a user-friendly spreadsheet-based tool was developed to assist designers in calculating hydrologic and volumetric parameters, proper sizing of silt fence segments, and for estimating maintenance needs. A case study and recommendation for state agency implementation demonstrates the application of the developed design approach
