Backyard Rain Garden

A shallow depression in the ground that captures runoff from a driveway, roof or lawn and allows it to soak into the ground, rather than running across roads, capturing pollutants and delivering them to a stream. The rain garden absorbs and filters pollutants and returns cleaner water through the ground to nearby streams. Rain gardens can also reduce flooding by sending the water back underground, rather than into the street.
