A rain garden is a shallow, constructed depression to catch rainwater. It contains plants that tolerate standing water for several hours. If it is designed properly, all water from a rain event will soak into the ground within 48-72 hours. Rain gardens receive a rush of polluted stormwater from hard surfaces (such as sidewalks, driveways, roofs, and streets), hold the water for a short period of time, and allow it to naturally soak into the ground. The plants and soil remove most pollutants so that the rainwater can recharge the groundwater with clean healthy water.
