Long Island has the most properties at risk out of the 12 metro areas in the projected wrath of Hurricane Irene, a report released Thursday said.
California-based CoreLogic, which collects property data, said 387,813 home and commercial properties here are at risk of flooding, accounting for 21 percent of the 1.87 million properties in major cities, from Cape Hatteras, N.C., to Boston.
Under federal law, homes and buildings in high-risk flood areas must have flood insurance. But there’s no mandate for those outside such areas.
CoreLogic said about 66 percent of the Island properties in the projected path are outside the flood zone designated by the Federal Emergency Management Agency. For New York City, it was 79 percent, the second highest, and at the top was Philadelphia, with 80 percent of properties outside FEMA flood zones.
