Weathering the Storm: Developing a Canadian Standard for Flood-Resilient Existing Communities

2019 – Intact Centre on Climate Adaptation

This report from the Intact Centre on Climate Adaptation presents a flood hazard and vulnerability screening framework that can help identify areas in existing residential communities that require the most immediate attention for flood risk. Drawing on extensive engagement with key stakeholders across Canada, this report highlights the following key considerations: age of development, history of flooding, design standards, proximity to the floodplain, topography, land use changes and intensification rates, sewer system types and presence of critical infrastructure. Application of the framework will enable communities to make better-informed decisions when prioritizing areas for flood-resiliency programming. The purpose of the report is to serve as a seed document for a future National Standard of Canada, which will be developed based on this framework.
