Rain gardens, sometimes called bioretention facilities, are shallow depressions with an absorbent soil medium, a mulch layer, and native grasses, shrubs, and trees that soak up stormwater from downspouts or impervious surfaces on a property. Rain gardens allow water to slowly soak into the ground rather than run off into streams and creeks. A rain garden is easy to maintain and helps to:
- Reduce pollution and erosion of local streams and rivers
- Improve the aesthetics of a community
- Replenish groundwater supplies
- Prevent flooding
- Provide habitat for wildlife.
