To direct the Director of the United States Geological Survey to establish a program to map zones that are at greater risk of sinkhole formation, and for other purposes.
Sinkhole Mapping Act of 2021
This bill directs the United States Geological Survey (USGS) to establish a program to map zones that are at greater risk of sinkhole formation.
Specifically, the USGS must
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 depicting the 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.
