Filter Strip/Level Spreader

Filter strips are vegetated buffers through which diffused stormwater runoff is filtered. The system includes a forebay to dissipate concentrated stormwater runoff, a channel with a level spreader to diffuse the flow, and vegetated buffer or filter strip through which the diffused runoff flows before it enters a waterway or ditch. The buffer is intended to remove sediment and pollutants before it reaches the waterway.
