Learn: Flood Mitigation Methods

Infrastructure and policy have interrelated to provide the province with measures to respond to and rebuild from flooding events. The June 2013 flooding in southern Alberta, however, set a new precedent in our province and initiated discussions of new mitigation methods capable of responding to intensified flooding and weather events.

In the aftermath of the spring 2013 flooding, Albertan’s across the province were questioning flood mitigation methods, what they were, how they worked, and how our province could move forward to address future flooding. The following are descriptions of main infrastructure and policy mitigation methods used to address flooding. Not every option is used in Alberta, some are examples taken from across Canada and around the world.

In May 2014, the Government of Alberta announced $28 million worth of mitigation projects had been completed in Canmore and the MD of Bighorn. Major mitigation projects are taking place across southern Alberta including High River, Rocky View County, Vulcan and Calgary. Since the June 2013 Flood, numerous community mitigation projects are on the way, and even more are being planned (for a full list of mitigation project visit the Flood Mitigation Projects webpage). 


The selection of mitigation methods explained here are not meant to be an endorsement for any one method. Instead, the tools listed are intended to provide basic information of what mitigation methods are available and how they work. This section of the website will continue to be expanded to address costs, impacts to the environment and watershed, and risks. Furthermore, this list is not complete and more mitigation methods still must be added.
