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.
