Landslide & Erosion

Managing Risk: Flood Mapping, Slope Stability And Risk Assessment.

This map shows the extent of natural hazard risk assessments completed by the CVRD. It is not a map of all natural hazards in the region; instead it shows those areas where the risks from a specific hazard have been studied. You can zoom in and click on an area to see what hazard or hazards have been assessed.

What is a landslide?

A landslide is a downslope movement of a mass of rock, earth, or debris and can happen without warning. Landslides occur in steep or mountainous areas when disturbances affect the natural stability of a slope. The type of subsurface materials that make up a slope can affect landslide risk. For example, areas with weak or fractured rock or varied soil layers can be more vulnerable. Risk of landslide has increased in the Cowichan region in recent years.

Together, we can shift the course of climate change impacts.

Read this brochure to learn about erosion and landslide risk in our region, how it could affect you, and information to help you be prepared.
