Homeowners in the “sinkhole alley” area of Hillsborough, Pasco and Hernando counties could buy expanded insurance coverage under a bill filed by Sen. Jack Latvala, R-Clearwater. The bill, SB 1274, filed last week, would once again allow insurance companies to offer homeowner protection for sinkhole damage that is deemed less than catastrophic. Looking to rein in the large number of claims being filed, some of them bogus, state lawmakers in 2011 approved a measure to restrict coverage only to the most serious structural damage to homes or businesses.
