This report is intended to provide a technically sound basis for BC local governments to develop coastal floodplain maps, and includes an estimation of Flood Construction Levels (FCLs), based on best mapping and engineering practices. In light of rising sea levels, coastal floodplain maps are needed so that local governments can define sea level rise planning zones for land use planning and development decisions. The report summarizes recommended standards for topographic mapping in the production of coastal floodplain maps. A sample coastal floodplain map and design brief for the City of Campbell River is included.
In conjunction with this project, a coastal flood hazard web application had been developed. It illustrates potential year 2100 floodplain areas in coastal BC, based on approximate FCLs.
