There’s a lot going on with respect to CT’s “coastal resilience,” that is, the capacity of the coastal ecosystem to respond to “a perturbation or disturbance by resisting damage and recovering quickly” (Wikipedia).
The basic resource is the Nature Conservancy’s Coastal Resilience CT Program (also see its “Adapting to the Rise: A Guide for Connecticut’s Coastal Communities”). The Nature Conservancy is working with two of the CT Councils of Governments (South Central and Greater Bridgeport) on a Regional Framework for Coastal Resilience in Southern Connecticut, with a $700,000 Hurricane Sandy Coastal Resiliency Competitive Grant (see a not up-to-date page on the project). It has also worked with the Southeastern CT COG on a Regional Resilience Guidebook. And the Western CT COG has a Hazard Mitigation page with much of the same sort of information.
Separate towns have drawn up completed or draft Coastal Resilience Plans, including Branford, Madison, and Milford (jointly under a Community Development Block Grant Disaster Recovery grant); West Haven; Stratford; Guilford; and Stonington. Groton has a document entitled “Preparing for Climate Change in Groton,” and Old Saybrook has one entitled “Report of Findings from a Study of the Effects of Sea Level Rise and Climate Change.” For Bridgeport, see the excellent Resilient Bridgeport and Rebuild by Design websites. Waterford appears to have started a resilience process in May.
For more information on coastal resilience in CT, see the CT Institute for Resilience & Climate Adaptation (CIRCA; at UConn) and a couple of videos on marshes on Shimon Anisfield’s page at the Yale School of Forestry & Environmental Studies.
