Over the past year, the Government of British Columbia (BC) has commissioned updates to its guidelines for managing coastal flooding. In 2010, BC released updated Guidelines for Management of Coastal Flood Hazard Land Use and earlier this year it released an update to its Dike Design and Construction Guide. The updates were drafted to reflect changes in baseline assumptions regarding sea-level rise, with BC policy now based on a estimated 1 metre of sea-level rise by 2100 and 2 metres by 2200. The guidance also indicates these assumptions will be revisited every five years. So it appears the new BC guidelines are perhaps a rather straightforward example of mainstreaming adaptation in action.
