Sinkhole Mapping Act of 2025

The Sinkhole Mapping Act of 2025 directs the U.S. Geological Survey (USGS) to study sinkhole causes - including extreme weather, drought, and water management shifts - and create updated risk maps showing areas prone to sinkholes. It requires the USGS to use specific 3D elevation data from existing law and maintain a public website with these maps for community planners and emergency managers. The maps must be reviewed and updated at least every five years. This bill directly affects local officials and emergency responders by providing accessible, science-based hazard information to inform land-use decisions and safety planning.
