The upswing in residential construction in the Charleston region over the past year means more properties are prone to storm surges in the event of a hurricane.
A new report looks to quantify the potential damage.
Real estate information firm CoreLogic released its annual hurricane report Friday, on the eve of the official start of the 2013 season. It found that the Charleston region has nearly 2,000 more properties at risk than a year ago, a gain of 2.5 percent.
The 81,484 properties in this year's tally are valued at more than $31 billion. Mount Pleasant leads the region dollar-wise with 12,605 properties valued at $5.1 billion.
For 2012, the Charleston region had 79,556 properties at risk, according to the CoreLogic. It was 10th among the top metropolitan areas at risk this year, unchanged from the previous ranking.
Hurricane damage has been a hot-button topic this year because of the after-effects of Superstorm Sandy, rising prices for standard insurance coverage and federal changes that could raise the cost of flood premiums for some property owners in the Lowcountry.
Among U.S. metro areas, New York City topped CoreLogic's risk rankings for 2013 with 455,255 properties valued at $168 billion that could be affected from hurricane damage.
As for states this hurricane season, CoreLogic ranked Florida the riskiest with 1.5 million properties in harm's way with a value of $386 billion.
South Carolina was No. 6 with nearly 196,784 properties valued at nearly $66 billion.
