Infiltration Feature
A small scale structure designed to retain stormwater from small impervious drainage area and infiltrate into unsaturated zone. Land surface modified to sustain maximum infiltration rates, typically consisting of vertical excavation of native soils and filling with coarse drain rock or other highly permeable material. Vegetation is absent. Typically, a small sized decentralized BMP, accepting runoff from a single land use drainage area.
