Note to Readers: The CoreLogic storm-surge analysis provided below was developed based on the projected path of Hurricane Sandy as of 12:30 p.m. ET Monday, October 29.
CoreLogic has released data showing the top 25 zip codes in New York City-Northern New Jersey-Long Island that are at risk of exposure to residential property damage from hurricane-driven storm-surge flooding when Hurricane Sandy hits the Atlantic coast later today. Massapequa, located on the South Shore of Long Island, holds the top spot with more than $4.6 billion in total structure value at risk.
In a report issued Saturday, CoreLogic also provided an estimate of the total number of residential properties at risk among the coastal Mid-Atlantic states, assuming Sandy hits the coast as a Category 1 hurricane. Within that seven-state region, nearly 284,000 total residential properties valued at almost $88 billion stand at risk:
According to CoreLogic, the number of residential properties in eight major metro areas and their respective potential exposure to damage are as follows:
CoreLogic reports that hurricane-driven storm-surge flooding can cause significant property damage when high winds and low pressure causes water to amass inside the storm, releasing a powerful rush over land when the hurricane moves on shore. The CoreLogic analysis measures damage from storm surge and does not include potential damage from wind and rain associated with hurricanes.
