Bioretention Standards – Another Tool in the LID Toolkit

National bioretention design and construction standards were developed as a National Research Council Canada’s Climate Resilient Buildings and Codes Infrastructure initiative. The standards were developed, under the auspices of the Canadian Standards Association Group, to provide a tool to support surface water protection and flood mitigation.

Proper stormwater management has become increasingly important as severe storm events become more commonplace, populations continue to increase, and development expands. Bioretention has been shown to provide many positive outcomes with respect to stormwater and the environment, the primary functions of which include: treatment of runoff; reduction of runoff volume; rate control; and groundwater recharge. These outcomes are strengthened by good Erosion and Sediment Control practices during construction of these systems and during construction of adjacent sites.
