Thanks to the Fraser River, Metro Vancouver residents live on one of the largest flood plains in the world. Significant floods took place in our region in 1894 and in 1948.
1) Where can I find flood hazard information?
Start by contacting your local government. Their flood plain bylaws are a valuable source of information. The Ministry of Environment (MoE) and the Provincial Emergency Fund (PEP) are also excellent resources for home buyers and home owners.
2) What is the extent and depth of potential flooding in the Fraser Basin?
This depends on the annual snowfall. For maps of the predicted flood levels, estimated flood plain boundaries and road networks, visit the Lower Mainland Dike Inventory and Emergency Maps at:
3) What is the "Flood Construction Level"?
This term describes the minimum elevation that is required for the underside of a wood floor system or top of concrete slab for habitable buildings in a flood-prone area. In the case of a mobile home, it refers to the ground level or top of concrete/asphalt pad on which the mobile home rests. Where the Flood Construction Level cannot be determined or where the overriding factors, an assessed height above the natural boundary of the water body or above the natural ground elevation may be used.
4) How can I find out if my property has been flood-proofed?
Compare the elevation of the main living floor with the flood construction level for the area.
5) Will there be a restrictive covenant on the land title?
Maybe, though there is some scepticism regarding how effective a restrictive covenant would actually be. Make sure to check the property title on a case-by-case basis.
6) Who is responsible for the flood protection structures in my community?
Flood protection structures are controlled by both private and public authorities. Public diking authorities are responsible for flood protection structures controlled by both the local diking authority and also by the local water authority. Privately-owned diking authorities are responsible for flood protection structures that surround either a specific development or a small community (i.e., Bowen Island)
7) Who is the diking authority in my community?
8) Can I purchase residential flood insurance?
No. In our province, flood insurance is only available for flooding due to pipes bursting, water mains failing, etc. It is not available for natural flooding.
9) Are there any government programs in place to provide assistance after a major flood?
The BC Disaster Financial Assistance Arrangements program is in place to assis with flood damage compensation and recovery. For more information, please visit: www.pep.bc.ca/dfa_claims/dfa.html
