An annual report from CoreLogic reveals that the number and value of total properties along the Atlantic and Gulf coasts at risk of hurricane-driven storm surge is increasing significantly.
In its 2013 analysis CoreLogic estimates that more than 4.2 million residential properties are exposed to storm-surge risk valued at roughly $1.1 trillion, with more than $658 billion of that risk concentrated in 10 major metro areas.
Florida tops the state rankings with nearly 1.5 million properties at risk and $386 billion in total potential exposure to damage.
Louisiana ranks second in total properties at risk with just over 411,000 homes in storm-surge zones, while New York ranks second in total value of coastal properties exposed at nearly $135 billion.
At the local level, the New York metropolitan area, which encompasses northern New Jersey and Long Island as well, contains not only the highest number of homes at risk for potential storm-surge damage, but also the highest total value of residential property exposed, at more than $200 billion.
CoreLogic makes the point that extensive regions along both the Gulf and Atlantic coasts are vulnerable to storm surge, and yet the homeowners who live in these areas are not required to carry flood insurance because they are not located within a designated FEMA 100-year floodplain.
Homeowners who live outside of the FEMA Special Hazard Flood Areas (SFHA), especially in the Northeast, would have little reason to carry flood insurance, given that they may not be aware of the risk storm surge poses to their properties.â€
CoreLogic notes that public awareness of the risk hurricane-driven storm surge poses to coastal homeowners has never been higher coming off the heels of Hurricane Sandy last fall.
A press release quotes Dr. Howard Botts , vice president and director of database development for CoreLogic Spatial Solutions:
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.â€
According to I.I.I. facts and statistics on flood insurance, Hurricane Sandy was the sixth costliest U.S. flood, based on National Flood Insurance Program (NFIP) payouts as of March 7, 2013.
