Over the last decade, flooding has become the costliest extreme weather disaster affecting Canadians^[2]. CSA Group has facilitated several research studies and standards to help protect property and infrastructure from floods. These standards provide requirements and guidelines for:

• flood resilient design of new communities
• identifying flood risks in existing communities
• managing stormwater systems
• design and construction of bioretention systems
• erosion and sediment control
• estimation of the intensity, duration, and frequency of rainfall events (i.e., IDF information)
• incorporating climate change into the development and interpretation of IDF information
• the collection, provision and use of weather data

CSA water standards can be leveraged by municipalities of various sizes and technical readiness levels. By incorporating these standards into strategic and municipal plans, bylaws, and other regulations, governments of all levels can consistently apply best practices in the design, construction, and management of water infrastructure. Using trusted, credible CSA resources developed by experts from across Canada, governments and municipalities can save time and costs, and gain the public’s confidence in measures taken to protect their communities.
