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.
