There’s a tremendous economic benefit that can come to citizens and businesses.” Nearly 19,000 claims have been filed since filing began June 4, Juneau said. The claims can range from economic losses, to coastal or wetland property damage. “People in various areas along the coast very likely have eligible claims,” he said. “When in doubt, file.” Juneau said people can file a claim online or at one of the 18 claims offices along the Gulf Coast, including Bridge City, Texas. The sites were opened after federal court Judge Carl Barbier gave the lawsuit preliminary approval May 2. A final approval hearing is set for Nov. 8, but Juneau said claim money could be paid before that. People who file claims can opt out of them by Oct. 1. The final filing deadline is April 2014. Those who were initially denied a claim by the Gulf Coast Claims Facility should reapply, he said.
