Rain Garden
A rain garden is similar to a natural wetland in that it captures and stores the rainwater that runs off parking lots and other hard surfaces. The long roots of the native plants and the special soil filter out impurities in the storm water and allow the water to slowly soak into the earth. Since rain gardens only hold water for a few days, mosquitoes are not an issue.
