Smart Bylaws Guide – Interim Report on the Effectiveness of Stormwater Source Control

The Greater Vancouver Regional District report Interim Report on the Effectiveness of Stormwater Source Control provides a quantitative reference on the effectiveness of different categories of stormwater source controls, including impervious area controls, absorbent landscaping, infiltration facilities, green roofs and rainwater re-use.  The report defines the hydrologic performance of each source control category for a range of land use types, soil conditions, rainfall conditions, and source control designs.  For each source control category, the report also provides design guidance and discusses cost implications, operation and maintenance requirements, and water quality benefits.  This information in this report helps local government staff to determine what can realistically be achieved through the application of source controls, determine which source control options are worth pursuing, and estimate the likely return on investment.
