Every year, flooding hits communities across Canada, causing millions of dollars in property damage and stress to homeowners.
New research from the University of Waterloo, funded by the Standards Council of Canada (SCC) and conducted by the Intact Centre on Climate Adaptation identifies 20 best practices to design and build new residential communities that are more flood-resilient.
The best practices were published in the report titled, Preventing Disaster Before It Strikes: Developing a Canadian Standard for Flood-Resilient Residential Communities.
Following consultation with municipal stormwater management experts, engineering consultants, developers, insurers and homebuilders, the report outlines best practices, including:
- Building new homes in areas that are not in floodways or in the flood fringe unless flood-proofing addresses flood risks.
- Increasing storm-sewer capacity in communities in anticipation of more severe rainfall.
- Designing streets to channel rainfall away from homes to safe discharge areas.
- Ensuring homes are well above potential water levels that follow extreme rainfall events.
- Ensuring that sewer-pumping stations are located in areas that remain operational during extreme rainfall, thus limiting the chance of sewer backup into homes.
“With the larger storms that we are seeing today, and the bigger ones that are coming, those who purchase homes in communities built in line with these recommendations will also be buying some peace of mind every time it rains,” said Blair Feltmate, a professor in Waterloo’s Faculty of Environment and the head of the Intact Centre.
The Intact Centre is seeking input on the effectiveness of the best practices to reduce flood risk and their practicality for implementation, as well as suggestions for additional best practices from municipalities, building practitioners and other interested parties. The deadline to provide input is October 31, 2017
