  Bioretention cells on Elm Drive, Mississauga, are lower then the adjacent road to accommodate a catch basin inlet between the paved surface and the cells.

A shallow excavated surface depression containing prepared filter media, mulch, and planted with selected vegetation.

An alternative practice to traditional impervious pavement, prevents the generation of runoff by allowing precipitation falling on the surface to infiltrate through the surface course into an underlying stone reservoir and, where suitable conditions exist, into the native soil.

Includes the protection of soil from dislocation by water, wind or other agents.

A mixture of mineral aggregates bound with bituminous materials, used in the construction and maintenance of paved surfaces.
