Abstract:
This report outlines 20 best practices for designing flood-resilient communities; specifically, for low-rise residential greenfield developments. It supports climate change adaptation efforts by contributing to the development of new standards for where communities are built and how. The report provides background on the economic and social risks associated with flooding, and identifies floods as the top climate change risk (i.e. most frequent and costly) to Canada’s communities. It is a rich resource for flood information in Canada, with: definitions of flood event types and risks (general and by Province), examples of stormwater and flood-related lawsuits in Canada, potential benefits of a national standard for flood-resilient communities, and draft best practices (for resilient design, storm sewer design, sanitary sewer design, street design, wastewater pumping design, and preservation of natural features).
 
Floods create significant challenges for local and regional governments, insurers, developers and individuals. This resource is useful to all of above, and provides a good range of high level concepts and concrete details to inform development design and regulation. The appendices contain wording from bylaws and regulations by province and are a great starting point for policy research on flooding
