There are questions over why oversight was eased at Mystic Camp as it expanded in a hazardous floodplain, the AP reported.

Federal regulators repeatedly granted appeals to remove Camp Mystic’s buildings from their 100-year flood map, as the camp operated and expanded in a dangerous flood plain in the years before rushing waters swept away children and counselors.

Camp Mystic owners successfully appealed to the Federal Emergency Management Agency to redesignate some buildings that had been considered part of a flood-hazard zone.
