摘要

Despite global mitigation efforts, climate change will impact the City of Vancouver's future. One anticipated impact, sea level rise, is described. A comprehensive understanding of the consequences of these impacts is necessary to guide the process of identifying preferred adaptation strategies. A methodology for a coastal flood risk assessment (CFRA) of sea level rise is provided. The inputs for this risk assessment include inundation mapping and an asset-at-risk inventory. These data sets are combined with flood damage information from Hazus to look at consequences of coastal flooding. There are many uncertainties and gaps in the process of developing a CFRA for a modern, dense, urban city such as Vancouver, particularly when the planning timelines required for preparing and adapting to sea level rise are long. The value of the process and results include increased understanding of hazards and vulnerabilities, and the development of useful visual tools for engagement, planning and education.
