What is a rain garden/bioretention cell?

A rain garden is a landscaped depression that captures rain water runoff from roofs, driveways/sidewalks, streets or compacted yards (impervious surfaces). The rainfall runoff captured in a rain garden is temporarily ponded, before infiltrating/percolating down through the soil. The installation of a rain garden helps restore a landscape's ability to manage water more sustainably by allowing rainfall to be absorbed through the soil to recharge groundwater and minimize stormwater runoff.
