Key West, Florida, is the southernmost point of the continental United States. It is known more for its snorkeling and scuba diving. With an average elevation of 4.7 feet above sea level, Key West is vulnerable to storm damage. Residents have learned to live with frequent flooding. A NOAA tidal measure in Key West has tallied an increase of 9 inches in sea level over the past century. To combat flooding, Key West has invested in one-way valves on storm drains to block seawaters from surging on to city streets.
8. Atlantic City, New Jersey
> Total population (2016): 39,306
> Homes at risk: 7,055
> Pct. of total pop. in at risk homes: 34.5%
> Value at risk: $1.05 billion
It’s a good bet that Atlantic City, New Jersey, one of the East Coast’s gambling meccas, will have flooding issues in the years to come. Nearly seven years ago, Superstorm Sandy shattered windows of casinos, forced residents to evacuate the city, and tore up the city’s famed boardwalk. Climate Central predicts a 74% risk of at least one flood over 5 feet occurring between now and 2050 in the Atlantic City.

> Total population (2016): 5,192
> Homes at risk: 8,109
> Pct. of total pop. in at risk homes: 33.8%
> Value at risk: $2.38 billion
Wildwood, New Jersey, less than hour south of Atlantic City, is famed for its Doo Wop-era motels. It also suffered during Superstorm Sandy. A report from the U.S. Army Corps of Engineers on the New Jersey Back Bay region this past March said construction of seawalls in Wildwood and Sea Isle City, will “manage risk for both high and low frequency events.” Construction of those storm walls may protect some of the more than 8,000 area homes at high flood risk.
