Natural Hazards

NEW - Updated Floodplain Mapping

The CVRD has updated the floodplain mapping for the Cowichan and Koksilah Rivers. This mapping takes into account new modelling data as well as projected climate change and shows areas likely to be subject to flooding during a 1 in 200 year flood. Flood construction levels are shown to guide development in floodplain areas. Other recent updates to flood mapping include Shawnigan Lake and the Riverbottom Road area.

Flood Mapping

Be prepared. Understand and manage the risks.

Cowichan is an amazing place to live. However, our region has natural hazards such as flooding, landslides, wildfires and earthquakes. We are also hit by extreme weather events like windstorms and heavy snow. Being aware of potential hazards and being prepared will help reduce the risks to you and your family.

Risk Tolerance Policy and Assurance Process

The CVRD has a Natural Hazard Risk Tolerance Policy to guide land use and development decisions in areas where hazards may present a risk the life and safety of residents. In areas subject to hazards such as landslides, you may be required to hire an engineer or geoscientist to prepare a geohazard risk assessment for your property prior to any development. 

The CVRD and Engineers and Geoscientists BC (EGBC) have partnered to establish a natural hazard assessment review and assurance process. While the CVRD Assurance Statement Form is comprehensive, it is intended to supplement, not replace, a natural hazard assessment report. The CVRD Hazard Acceptability Thresholds and CVRD Hazard Assurance Guide provide guidelines to support completion of the Assurance Statement.
