Methodology

To identify the cities that will soon be underwater, 24/7 Wall St. reviewed data from “When Rising Seas Hit Home,” published July 2017 by Cambridge Massachusetts-based environmental watchdog group the Union of Concerned Scientists. The study identified U.S. coastal communities where the largest number of residents live in properties that are projected to face by 2060 the highest level of chronic and disruptive flooding, or effective inundation — defined as having 10% or more of livable land area flooded at least 26 times per year. We reviewed the number of properties and total value of properties that are exposed to flood risk based on a “high” scenario calculated by the Union for Concerned scientists, which entails a 6.5 foot rise in sea level by the end of the century. The places on our list, which are county subdivisions, are those in which the largest number of residents live in housing that is exposed to the effective inundation.
