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.

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.

FEMA approved requests to lift flood restrictions on Camp Mystic buildings for years, enabling expansion in a known hazard zone before the July 4 flash floods killed at least 27 people.
