Rain Gardens

Rain gardens are shallow depressions planted with different types of flowers, grasses or shrubs that collect storm water and allow it to soak into the ground.  They can be located in various places on a property to treat different sources of storm water.  Storm water can carry a significant amount of pollutants to our streams, lakes and wetlands.  Urban/residential development (rooftops, driveways and sidewalks) increase the quantity of water draining to streams and rivers (too much) and the rate of the runoff (water runs off faster creating higher peak flows.)  A rain garden is a practical yet aesthetically pleasing means to reduce the impacts of development.

There are three rain garden demonstration projects in Woodstock where you can see what they look like and how they work:

  • Woodstock Historical Society
  • Roseland Park Golf Course
  • Woodstock Town Hall 

The Woodstock Conservation Commission encourages homeowners to plant rain gardens on their property if it is practical to do so.  Contact the staff of the Eastern CT Conservation District if you would like more information on rain gardens.
