The Coastal Infrastructure Vulnerability Index (CIVI) was jointly developed by DFO Science Branch, Small Craft Harbours (SCH) Program and the Economic Analysis and Statistics Directorate. The CIVI was designed with the intent of developing a climate change adaptation tool that would support management decisions regarding the long-term infrastructure planning for SCH sites. The CIVI provides a numerical indication of the relative vulnerability of small craft harbour sites to the effects of climate change and was designed with three component sub-indices: Environmental Exposure (natural forces), Infrastructure, and Socio-economic. The spatial component for the coastline was derived from the CanVec 1:50,000 hydrographic layer (https://open.canada.ca/data/en/dataset/9d96e8c9-22fe-4ad2-b5e8-94a6991b744b). This layer combines the 1:50,000 CanVec coastline of Canada with the following CIVI environmental exposure variables: projected sea level rise (for the decades 2030, 2040,...2100) in meters wave height (metres) and wind speed (metres/second) change in sea ice coverage in Atlantic Canada from the 1970s to the 2000s Sea level change: Data for relative sea level change (SLC) were…
