→Bioretention
This study compares the hydrologic, water quality and functional performance of a [[Bioretention]] cell and [[Infiltration trench]] that drain runoff from a parking lot at the Living City Campus in Vaughan, Ontario. The practices have identical drainage and subsurface infiltration areas, and both receive runoff through geotextile-lined stone inlets. Key parameters examined include runoff volumes, runoff volume reduction, surface ponding and infiltration, water quality, effluent water temperatures, soil moisture and operation and maintenance requirements. To view the performance results for both features click the button above.

This study evaluates the performance of a [Bioretention]] system that treats runoff from a commercial parking lot (Earth Rangers, located in Vaughan, ON.). Key parameters examined include runoff volumes, runoff reduction, surface ponding and infiltration, water quality, surface soil and effluent water temperatures, soil moisture and operation and maintenance requirements. Results show that bioretention systems can significantly improve the management of stormwater runoff from parking lots and other small drainage areas relative to conventional treatment practices. Runoff volumes were reduced by over 90% and the mass of pollutants discharged from the facility was between 65 and 92% less than that discharged from a nearby asphalt pavement.
