A rain garden is a planted depression in the landscaping that collects and stores storm water runoff from roofs, driveways, walkways, parking lots, and compacted lawn. The storm water is stored in a rain garden until it can infiltrate into the soil.
The rain garden can be designed and customized for an individual or a neighborhood. By creating a landscaped rain garden it provides a natural habitat for plants, birds, butterflies and other insects and can be enjoyed year round.
The advantages of a rain garden help to prevent flooding and erosion and turn storm water issues into a water supply for use. It is easy to maintain and only requires a little time and energy. The storm water is reusable (for non-drinking purposes) and is suitable for irrigation; therefore, reducing the cost of water bills. A rain garden may help to meet township requirements when impervious surface coverage increased.
