A growth in urbanization has caused an increase in impervious surfaces. The result of this is an increase in stormwater runoff. Stormwater runoff is defined as rain, melted snow and ice from a roof, driveway or any type of impervious surface. Stormwater collects in a storm sewer system and empties into our local waterways. Along the way, stormwater collects many pollutants such as road salt, heavy metals, and oils, which can harm water quality and aquatic life. One way to decrease stormwater pollution and encourage rainwater to infiltrate into the ground is a RAIN GARDEN!
What is a rain garden?
A rain garden is a shallow depression planted with native plants and flowers. A rain garden is designed to collect and absorb rain and snowmelt from roofs, sidewalks, driveways, and lawns allowing it to seep naturally into the ground. A rain garden allows up to 30% more water to soak into the ground than a typical patch of lawn. A rain garden is beneficial because it will:
- Recharge local groundwater
- Reduce mosquito breeding by removing standing water
- Create a habitat for birds and butterflies
- Reduce the potential of home flooding
- Protect rivers and streams
