Summary

Official summary (Introduced in House, 2025-01-31):

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.
