A rain garden is a depression created in a landscape that allows water runoff from rooftops, driveways, and/or streets to pool or be ponded. The water does not stay, it only captures this runoff and allows it to infiltrate into the ground recharging groundwater instead of running off into our sewer systems and in turn into our rivers and streams. Rain gardens are an infiltration-based storm water treatment management system. The idea here is to add beauty in the landscaping of these rain gardens while also treating home's rooftop and driveway runoff, which allows them to be both aesthetically pleasing and a hydraulically pleasing system.
