Primary Purposes
To remove sediment and other pollutants from runoff by filtration, deposition, infiltration, or plant uptake.
Key Design Elements
Strips are planted cross-slope or on the contour downhill from the source of sediment or pollutants. They must be sufficiently wide to achieve primary purposes.
Tree/Shrub Species Requirements
- Adapted to the soil and climate of the planting site.
- Tolerant of sediment deposition and pollutant-laden runoff.
- Moderate to aggressive development to occupy the site quickly.
- Resistance to pests and herbicides.
