Treating Runoff at the Source
Rain gardens are beautiful landscape features, but also help keep our lakes and streams clean. A rain garden's job is to filter and soak in storm water runoff that would otherwise go into nearby waterbodies, usually through the curb and gutter system. Storm water from roofs, driveways, streets, and other hard surfaces is directed into the rain garden, which is in a depression. The garden is planted with plants that can tolerate periodic flooding. Standing water exists for only 2-3 days, eliminating mosquito breeding.
