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

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.

Federal regulators repeatedly granted appeals to remove Camp Mystic's buildings from their 100-year flood map, loosening oversight as the camp operated and expanded in a dangerous flood plain in the years before rushing waters swept away children and counselors, a review by The Associated Press found.

Over 120 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

The death toll in the July 4 Central Texas flooding rose to 103 on Friday as the search continued for those still missing.
