Rain gardens, sometimes called bioretention, 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 infiltrate into the ground rather than run off into streams and creeks. The benefits of rain gardens include:
- They help reduce pollution and erosion of local streams and rivers
- They improve the aesthetics of a community
- They replenish groundwater sources
- They are relatively inexpensive, low-tech, and easy to maintain
- They help prevent flooding
- They provide habitat for wildlife
