Researchers from the University of Waterloo are the latest to recommend a standard across Canada for flood protection in communities at risk of overland flooding. The university says the nationwide standard should employ two dozen best practice. Such a standard would build protection and reduce water-related losses, including sewer back up protection.
One important part of the standard would be to prevent new homes being built in floodways or in the flood fringe. The only exception would be if flood-proofing measures are taking. Researchers published their findings in the report, titled Preventing Disaster Before It Strikes: Developing a Canadian Standard for Flood-Resilient Residential Communities.
The research was conducted in partnership between Intact Centre on Climate Adaptation (ICAA) and funded by the Standards Council of Canada (SCC).
Among the report’s recommendations are:
The standards and best practices would cover overland flooding, riverine flooding, storm and sanitary sewer surcharge, drainage system failures, and groundwater seepage. Standard measures would also help to reduce costs, both insurance and uninsured.
Some specific recommendations include the following:
“Ensuring that new communities are built under the direction of these practices is necessary to combat ever-worsening extreme weather that, if not addressed, will result in costly and unremitting flood damage,” states the report.
“These best practices constitute elements of residential community design and construction that, if implemented together, should achieve significant flood risk reduction,” the report adds.
