Bioswale

Urban Farm DB summary

A bioswale is a vegetated drainage channel that captures and breaks down sediment, organic matter, pathogens, nutrients, and heavy metals from stormwater runoff via plants and soil. At Willamette River Park in Portland (1996), 2,330 lineal feet of bioswale reduced suspended solids entering the river by 50%, and New York City has built more than 11,000 curbside bioswales.
