Resilient Connecticut Story Map

Resilient Connecticut Story Map

CIRCA partnered with Milone & MacBroom to create a story map that gives an overview of Resilient Connecticut and explains a new climate change vulnerability mapping tool for flood, heat and wind stressors. Zones of shared risk and an interactive map showing previous resilience planning projects are also featured. Visit the tab to Provide Input if you’d like to take a survey, give feedback on the map tools, or identify vulnerable areas in your community.

Climate Change Vulnerability Index

Climate Change Vulnerability Index

Demo the latest climate vulnerability mapping tool for flood, heat and wind stressors. The Climate Change Vulnerability Index (CCVI) is a regional tool developed for New Haven and Fairfield Counties that can be used, in conjunction with other resources, for planning and developing purposes. Additional CCVI resources include fact sheets, previous workshop materials, and links to reports describing Connecticut's climate projections for precipitation, heat, and sea level rise to 2050 and beyond.

Connecticut Coastal Towns Storm Annual Exceedance Probability/Return Interval

Connecticut Coastal Towns Storm Annual Exceedance Probability/Return Interval

The highest 44 storms between 1950-2018 were reproduced using a coupled circulation and wave model to show the annual exceedance probability (or return period) of storm surge water levels and significant wave height for each of Connecticut's 24 coastal towns.  The results presented in a tool, data, and journal article  highlight the storm surge water levels and significant wave heights, which may contribute to a better understanding of extreme storms and guide decision-makers.

Coastal Vulnerability Index

Coastal Vulnerability Index

This map viewer is a GIS based tool to express a one-dimensional, interactive risk index at multiple scales. The influence of different factors to the effects of sea level rise are incorporated to help users visualize the relationship between environmental, socio-economic, and built contributors in terms of exposure, sensitivity, and adaptive capacity at a range of locations. The tool indicates a high to low rank for coastal vulnerability from the impacts of sea level rise.
