British Columbia Floodplain Maps


* See updated Merritt, B.C map link at bottom (Nov. 2021)

British Columbia maintains a comprehensive index of maps showing floodplains, or flood hazard limits / flood areas, throughout the province of BC.  These maps illustrate flood risks associated with large river systems as opposed to urban overland flow systems that can cause urban flooding.

The map to the right is an overview of BC flood map areas.  Use the links in the list below to find the floodplain map for a particular river, creek, reservoir or lake.

Langley Floodplain Map
To the left is an example of a floodplain map for a particular area - in this case for Langley, B.C. (click to enlarge).  Zooming in shows buildings and properties that lie within the flood risk zone.  I have spliced together parts of two maps to show an area near the Langley Bypass and Frazer Highway with residential properties within the flood hazard area.

Close-up of buildings in flood risk zone.
Variable river flooding depths for rare event.
The maps show over a hundred buildings within the risk zone.  Remember this map shows the limits for a 200-year floodplain - this is the limit of river flooding during a 200-year rainfall event, which is and extreme storm having a chance of occurring of 0.5% every year (1/200%).  While this seems rare, if you lived in one of the buildings at the edge of the flood hazard (i.e., right on the floodline), you would have had a 22% change of being flooded over that period.  This risk is often misreported by saying you would expect that flood event once in every 200 years (this implies a 100% chance over that period).  In fact in 200 years there is only a 63% chance of being flooded.

Th bird's eye view shows some of the variation in flooding depth based on the map's topographic elevations and flood elevations that vary along the river length.  You can see that the flood depth varies considerably.  The townhomes that have 130 cm of flooding during that flood would have a much higher chance of being flooded during a smaller storm than those with only 10 cm of flooding during the 200 year flood event.  Alternatively, for any given storm, the flood damages would be greater the closer the building is to the valley bottom with deeper flooding.

Based on flood risk mapping, do you need flood insurance for your property? Find and insurance broker through the The Insurance Brokers Association of B.C. here.
