Overview
Flood studies include engineering reports and maps. Studies are considered final after formal finalization is completed. The standard finalization process includes staged local authority review and public engagement components.
Final flood maps are not available in all communities. The best way to view available final flood mapping is through the provincial Flood Awareness Map Application, including final flood inundation and flood hazard maps. Copies of final flood study reports and related information are available on request.
Final studies
The studies listed below are final. Basic information for each final study and direct links to online flood hazard maps are provided, along with notification if a new study is currently underway that will eventually replace the final study.
