The CVRD has updated the flood and erosion hazard mapping for Shawnigan Lake and the Riverbottom Road area of the Cowichan River. 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.
The CVRD has a 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 policy is available here.
