The Village of Park Forest recognizes the stormwater management and water quality benefits of reduced site runoff associated with the installation of rain gardens. Rain gardens capture and hold water, usually through the use of native plants. Rainfall and stormwater runoff can drain more effectively when using highly-porous plant materials. Rain gardens allow approximately 30 percent of runoff to be filtered into the ground. A properly-designed rain garden can filter one inch of rainfall in four hours.
In order to encourage its residents to install rain gardens, The Village of Park Forest has created the Residential Rain Garden Incentive Program to manage stormwater, as well as adding aesthetic elements to residential lots.
