Rain Gardens

Rain gardens treat stormwater runoff generated by your property by acting like a native landscape and filtering runoff and pollutants through the soils and plants.

A rain garden works by collecting stormwater runoff from a roof, driveway, or parking lot that would otherwise go to the street or storm drain. The water temporarily ponds on the surface of the garden and then slowly filters through the soil media and/or is taken up and used by the plants. The garden is planted with a mix of native plants that filter out pollutants and attract wildlife.
