Sediment Fence with Skirt

Abstract

Sediment Fence with Skirt is designed to help meet the requirements of the National Pollution Discharge Elimination System for sediment control as well as provide a physical base for site and soil remediation. The primary function of the Sediment Fence with Skirt is sediment control and it can be installed on project boundaries as well as across drainage flow lines. Surface water and drainage water flows through the sediment fence tube and sediment is removed from suspension by filter material in the sediment fence tube, and by the interruption of flow velocity, which will cause sediment to drop out of suspension. Erosion control is enhanced by the use of the attached Sediment Fence skirt, which is plowed into the ground or affixed to the surface at the time of Sediment Fence installation, and which provides a barrier to reduce leakage of surface and drainage water underneath the Sediment Fence.

1 . A sediment control system that reduces or eliminates leakage of runoff or other discharge flow underneath the bottom edge of the sediment fence (see  FIG. 1 ).  
   
   
       2 . A sediment control system that can be left in place to provide long-term sediment control and a planting matrix for groundcover crops (see  FIG. 1 —Optional Seeding Skirt).  
   
   
       3 . A sediment control system that allows flexibility in choice of filter material depending on the needs of the project and the requirements of the site ( FIG. 1 —General Notes).  
   
   
       4 . A sediment control system that allows materials harvested on a project site to be used for sediment control filter material (also see General Notes and  FIG. 1 ).  
   
   
       5 . A sediment control system that is installed into the ground mechanically and that does not require staking to the ground, but offers a means to optionally stake the fence into the ground for situations that require additional support (see  FIG. 2 ).
