Improved Understanding of Sea Level Rise Vulnerability Leads to New Policies

Southeast Florida is one of the first areas in the continental U.S. to be impacted by sea level rise. When local governments sought data and information to assess and prepare for the problem, GIS practitioners from the Southeast Florida Regional Climate Change Compact were able to work with NOAA Office for Coastal Management experts to answer this need.

Elevation data from NOAA’s Digital Coast and the agency’s Sea Level Rise Viewer were used to create digital maps featuring sea level rise scenarios of 1, 2, and 3 feet for each Southeast Florida county. Counties used this information to perform vulnerability assessments for specific infrastructure using regionally consistent methods and create a report outlining impacts that may occur under each of the three scenarios. The resulting new policies and programs are helping these communities address sea level rise, adapt to its impact, and improve community resilience.
