Harvey Costs Seen at Catastrophic Levels With Many Uninsured - Bloomberg
"Most people with flood insurance buy policies backed by the federal government’s National Flood Insurance Program. As of April, less than one-sixth of homes in Houston’s Harris County had federal coverage, according to Aon. That would leave more than 1 million homes unprotected in the county. Coverage rates are similar in neighboring areas. Many cars also will be totaled."
