More than 4.2 million homes along the U.S. Atlantic and Gulf coasts are in risky zones for hurricane-driven storm surge flooding, according to a new report from CoreLogic, a property information and analytics company headquartered in Irvine, Calif.
More than a half-million properties are at risk in the New York City area alone. Value of the at-risk properties from Texas to Maine totals more than $1.1 trillion.
Storm surge -- rising ocean water driven by wind -- caused much of the Hurricane Sandy devastation last year.
"Sandy was a harsh reminder of the potential destruction associated with storm-surge flooding, and of just how many communities are vulnerable to that risk, in areas typically assumed to be relatively safe from hurricanes along the northeastern Atlantic shoreline," Howard Botts, vice president and director of database development for CoreLogic Spatial Solutions, said in a press statement.
Florida has almost 1.5 million properties worth $386 billion at risk for storm-surge flooding, more than any other state.
More than $658 billion of the coastal risk is concentrated in 10 major metro areas. Those cities and the number of properties at risk and their value are:
- New York, 447,428, $205.7 billion
- Miami, 239,910, $100.1 billion
- Virginia Beach, N.C., 305,943, $73 billion
- Tampa, 301,045, $55.1 billion
- New Orleans, 238,919, $43.7 billion
- Cape Coral, Fla., 198,020, $42.9 billion
- Wilmington, N.C., 114,695, $38.2 billion
- Naples, Fla., 76,104, $34.5 billion
- Bradenton, Fla., 138,226, $33.8 billion
- Charleston, S.C., 81,484, $31.5 billion
