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, as the camp operated and expanded in a dangerous flood plain in the years before rushing waters swept away children and counselors.

Young girls, camp employees and vacationers are among the at least 120 people who died when Texas' Guadalupe River flooded.

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

Over 100 people have died after heavy rain pounded Kerr County, Texas, early Friday, leading to "catastrophic" flooding, the sheriff said.

Dick Eastland, the Camp Mystic owner who pushed for flood alerts on the Guadalupe River, was killed in last week’s deadly surge.

Records released Tuesday show Camp Mystic met state regulations for disaster procedures, but details of the plan remain unclear.
