Natural Hazards

Our region is home to a number of historical landslide areas. These are typically slow-moving slides, which creep progressively over a period of months or years. While this shifting land movement generally does not pose immediate risk or danger to life, it can cause significant damage to buildings, roads and other infrastructure. 

Please review the attached documents below for more information. Or, if you have any questions, please email landstability@williamslake.ca or contact our office at 250-392-2311 and ask to speak to someone regarding the slope stability study.

City of Williams Lake Geotechnical Hazard Area Mapping and Assessment

As part of a proposed update to the City of Williams Lake Official Community Plan, a review and update of the City’s geotechnical hazard area mapping and assessment is being released to the public.

In 2022, engineering consultants Palmer Environmental Consulting Group (PECG) reviewed and updated the City’s geotechnical hazard area mapping and assessment by analyzing existing data with results from newer studies and reports. PECG’s report utilized all available data, including the results of recent Light Detection and Ranging (LiDAR) scans.

The PECG’s study replaces the City’s previous geotechnical hazard report published in 2006 and incorporates more recent geotechnical investigations by multiple agencies within City boundaries, as well as utilizes LiDAR studies encompassing a larger portion of the municipality.

Please note, residents who have concerns regarding their property should consult with a professional engineer or geoscientist for specific interpretation of the results.

The most recent City of Williams Lake Geotechnical Hazard Area Mapping and Assessment report (as of September 11, 2023) is now available at the link below:
