An amendment to BC’s Flood Hazard Area Land Use Management Guidelines
incorporating sea level rise into building setbacks and flood construction in coastal areas will come into effect January 1, 2018. Local governments are required to consider the Flood Hazard Area Land Use Management Guidelines in development and land-use management planning and approval decisions for flood hazard areas.
The amendment is based on a 2011 technical report commissioned by the Province, which recommended incorporating sea level rise into planning and development to ensure a standard of public safety into the future. The amendment recommends that coastal communities allow 1.0 m sea level rise by 2100 and 2.0 m sea level rise by 2200 (relative to the year 2000 and considering regional uplift and subsidence). It provides recommended flood construction levels and setbacks that local governments are required to consider when making bylaws for designated sea level rise planning areas. The definition of and methodology for the determination of flood construction levels and setbacks for coastal areas have also been modified.
