What is a rain garden?
A rain garden captures stormwater runoff and allows it to slowly soak into the ground. The water that washes off your roof, driveway and your lawn, called stormwater runoff, becomes contaminated by the everyday substances found around your home. In a rain garden, layers of soil and water-loving plants naturally filter and remove pollutants before they flow through the storm drain pipes and into our local streams. These gardens can absorb several times more rainwater than a lawn, while replenishing the groundwater supply and filtering pollutants. They are easy to maintain and, after the plants are well-established, rarely need watering. They also provide a habitat for birds and butterflies.
