Federal Floodplain Mapping Framework

In Canada, overland flooding costs the Canadian economy more than any other hazard we face, and is the single largest draw on the Disaster Financial Assistance Arrangements (DFAA). Floodplain mapping identifies the boundaries of a potential flood event and is critical to support informed decisions and investments to reduce the impacts of flooding in communities across Canada. In consultation with provincial and territorial partners and key stakeholders, the federal government has developed the first iteration of the Federal Floodplain Mapping Framework. The Framework is the first in an evergreen guidelines series, which will inform any individual or organization involved with floodplain management in Canada. The publication of the Framework will contribute to better addressing overland flooding – Canada’s costliest hazard – by strengthening floodplain mapping across the country.
