Information: A rain garden, a term familiar to the general public, is a bioretention practice.

Bioretention practice is a terrestrial-based (up-land as opposed to wetland) water quality and water quantity control process. Bioretention employs a simplistic, site-integrated design that provides opportunity for runoff infiltration, filtration, storage, and water uptake by vegetation. Bioretention is an important green stormwater infrastructure practice.
