Rain gardens are just what they sound like; a regular garden in your yard filled with native plants and grasses that are designed to absorb water. It is located in your landscape to receive runoff from hard surfaces such as a roof, sidewalk, or driveway. Rain gardens slow down the rush of water from these hard surfaces, hold the water for a short period of time, and allow it to naturally infiltrate into the ground. This helps keep clean, fresh rainwater out of the sewer system that could otherwise carry with it pollutants like oil, salt, fertilizer, and pesticides. Rain gardens are a beautiful and colorful way for homeowners, businesses and municipalities to help ease stormwater problems.
