Rain Gardens

Rain Garden IcoonRain 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.
