Sinkhole Mapping Act of 2025 passed the House 164 days after introduction and awaits a vote in the Senate

Sinkhole Mapping Act of 2025 This bill directs the U.S. Geological Survey (USGS) to establish a program to study the short-term and long-term mechanisms that cause sinkholes, including extreme storm events, prolonged droughts causing shifts in water management practices, aquifer depletion, and other major changes in water use; and develop maps, using three-dimensional elevation data, that depict zones that are at greater risk of forming sinkholes. The USGS must establish a public website that displays such maps and other relevant information critical for use by community planners and emergency managers.
