A rain garden is a sunken garden bed that captures stormwater runoff from hard surfaces like rooftops, sidewalks and driveways, and allows it to soak back into the ground naturally. They are planted with hardy, native perennials that filter pollutants commonly found in stormwater runoff. This helps reduce the overall amount of runoff and pollution that gets into our streams, and maintains the natural hydrology so streams don’t go dry during the hot summer months.
Why build a rain garden?
When a landscape is covered in natural vegetation, most rainfall soaks into the ground. As we start adding roofs, driveways, sidewalks, and streets to the landscape, much of the rainfall can’t soak into the ground anymore. This can create a lot of problems for people and for our streams.
Rain gardens hold stormwater runoff and allow it to soak into the ground naturally. This helps reduce the amount of pollution that gets into our streams. It also maintains the natural hydrology so streams don’t go dry during dry spells.
Rain Gardens are:
- Are an easy way for all of us to do our part to protect our streams and rivers.
- Are planted with beautiful, hardy, low-maintenance perennial plants.
- Provide food and shelter for birds, butterflies and beneficial insects.
