A rain garden is a depressed, landscaped garden planted with native plant species that is designed to retain and infiltrate stormwater runoff from individual residential or commercial lots, sump pumps and roofs. Rain gardens are versatile features that can be installed in almost any unpaved space. Rain gardens have also been used successfully along streets to reduce and filter street runoff.
