Landslides

As our cities, towns, roads and highways steadily encroach onto steeper slopes and mountainsides, landslide hazards become an increasingly serious threat to residents, infrastructure and natural resources.

Get to Know Your Watershed

By getting to know your watershed, and monitoring creeks near your property, you can become familiar with typical flow patterns and recognize changes that may indicate a potential hazard upstream.

  • Learn the history of landslides and debris flows on or near your property and the areas you visit often. Flood hazard mapping is available through your local government and is a good first step
  • Be aware of dikes or flood control structures that may be protecting your property - some of these may not be maintained any longer. Check with the B.C. Dam Safety Program if you have any concerns or questions
  • Do not build near steep slopes, close to mountain edges, near drainage ways or natural erosion valleys
  • Hire a qualified professional to conduct a ground assessment of your property
  • Develop a household plan, put together your emergency kit and connect with your neighbours. Learn about the emergency response plan for your area

Recognize the Warning Signs

Call your local fire, police, or public works department if you see any of the following:

  • Rapid increase or decrease in creek water levels
  • Abnormally dirty water
  • Sudden or rapid changes in flow or sediment
  • Unusually large and recent accumulation of debris (logs, sediment, etc.)

Leave the area immediately if you observe the following:

  • A faint rumbling sound that increases in volume
  • Unusual sounds, such as trees cracking or boulders knocking together

After a Landslide      

  • Stay away from the slide area as there may be danger of additional slides
  • Listen to local radio or television stations for the latest emergency information
  • Watch for flooding, which may occur after a landslide or debris flow
  • Help a neighbour who may require additional assistance, such as those with infants, elderly people and people with disabilities
