By JOE RYAN joe.ryan@newsday.com An attorney for the Federal Emergency Management Agency Tuesday said the organization was investigating allegations that engineering reports were secretly rewritten after superstorm Sandy to deny claims on government-funded flood insurance policies.FEMA associate general counsel Jordan Fried told a panel of federal judges in Brooklyn that the agency was troubled by reports that private insurance and engineering companies had conspired to falsify documents to partially reject a settlement for homeowners in Long Beach.”We are investigating it and we will look at everyone involved,” Fried said before three magistrates overseeing all Sandy lawsuits filed in the Eastern District of New York, which includes Long Island.After the hearing, Fried said FEMA hadn’t determined yet whether it would undertake the probe itself — or refer the matter to the U.S. Department of Homeland Security Office of Inspector General. He declined to comment further.Fried’s comments come nearly three weeks after one of the three magistrates — Judge Gary Brown — issued a ruling saying it appeared engineering reports may have been routinely doctored to avoid paying claims. Brown’s ruling orders all insurers being sued over Sandy claims to release copies of their draft engineering and adjusting reports. FEMA has appealed that mandate.Updated November 25, 2014 7:12 PM
