Soak Up the Rain: Rain Gardens
A rain garden is a depressed area in the landscape that collects rain water from a roof, driveway or street and allows it to soak into the ground. Planted with grasses and flowering perennials, rain gardens can be a cost effective and beautiful way to reduce runoff from your property. Rain gardens can also help filter out pollutants in runoff and provide food and shelter for butterflies, song birds and other wildlife.
More complex rain gardens with drainage systems and amended soils are often referred to as bioretention.
Note: Refer to the links in this section for important tips on how to locate your rain garden. These include areas to avoid and the need for accurate information about underground utilities before you begin to dig.
