The FEMA Flood Map Service Center offers an interactive map that allows anyone in the U.S. to enter their address and see if they live in a designated flood zone. The tool can also be used to explore other areas, making it helpful for those planning a move, managing a rental property or checking on family or friends in another region.

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.
