Federal Flood Mapping Guidelines Series

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). Flood 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 new documents in the Federal Flood Mapping Guidelines Series. These are a series of evergreen guidelines that will help advance flood mapping activities across Canada. The publication of these documents will contribute to better addressing overland flooding – Canada's costliest hazard – by strengthening flood mapping across the country.
