That’s how much it would cost to rebuild 112,000 homes in the Charleston area that could be damaged from storm surge after a direct hit of a major hurricane, according to a new report. If the entire coast of the state took a hit, the cost would be a whopping $70.4 billion, according to the CoreLogic coast. Lesson: Cool out on the building along the coast (Hear that, folks at Capt. Sam’s Spit near Kiawah Island, where a couple of pieces of heavy machinery fell into the ocean because of the fragile landscape?) More.
