A rain garden is a planted depression that allows rainwater
runoff from impervious urban areas like roofs, driveways,
walkways, and compacted lawn areas the opportunity to be
absorbed. This reduces rain runoff by allowing stormwater
to soak into the ground (as opposed to flowing into storm
drains and surface waters which causes erosion, water
pollution, flooding, and diminished groundwater).[1] Rain
gardens can cut down on the amount of pollution reaching
creeks and streams by up to 30%. (See some rain
gardens below)
