“FBI agents are interviewing employees at FEMA in an investigation of unusual changes in federal flood insurance maps that benefited oceanfront condo buildings with a history of flooding, according to sources familiar with the investigation. The investigation follows a report by NBC News documenting more than 500 instances in which FEMA has remapped waterfront properties from the highest-risk flood zone, saving the owners as much as 97 percent on the premiums they pay into the financially strained National Flood Insurance Program. FBI agents have conducted interviews in Washington over the past 10 days with employees of the Federal Emergency Management Agency, which oversees the flood insurance program. Others outside the government also have been interviewed and have voluntarily provided documents, according to two people interviewed by the FBI. Employees at contractors that evaluate the map changes for FEMA are also being interviewed.”
