  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.

  The grade and lack of curb allow for sheet-flow runoff into this bioretention facility. Lakeside Park, Mississauga, ON

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.

Ground depression acting as a flow control and water treatment structure, that is normally dry.

That potion of the water precipitated onto a catchment area, which flows as surface discharge from the catchment area past a specified point.

Water from rain, snow melt, or irrigation that flows over the land surface.

Refers to a system that when full, stormwater will bypass the practice. Offline systems use flow splitters or bypass channels that only allow the water quality volume to enter the facility. This may be achieved with a pipe, weir, or curb opening sized for the target flow, but in conjunction, create a bypass channel so that higher flows do not pass over the surface of the filter bed.

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

A shallow constructed channel, often grass-lined, which is used as an alternative to curb and channel, or as a pretreatment to other measures. Swales are generally characterized by a broad top width to depth ratio and gentle grades.

Vegetated, open channels designed to convey, treat and attenuate runoff. Design variations range from simple grass channels, which are designed primarily for conveyance to more complex treatment and volume reduction designs like enhanced grass swales, and dry swales or bioswales.
