National Landslide Preparedness Act Reauthorization Act of 2025

This bill reauthorizes through FY2030 and expands the National Landslide Hazards Reduction Program (NLHRP) of the U.S. Geological Survey (USGS) and reauthorizes and expands other related programs.

The bill reauthorizes the NLHRP’s activities including analyzing, preparing for, and responding to landslide hazards. It specifies a minimum amount of NLHRP funds that must be used for deploying landslide early warning systems in high-risk areas. It also specifies that tribal organizations and Native Hawaiian organizations may receive the benefits of the NLHRP.

Also, the bill expands the NLHRP by requiring the USGS to incorporate atmospheric rivers and extreme precipitation events into the program’s national strategy, resources for communities on landslide preparedness, and emergency response activities. It requires a landslide hazards database to include information regarding identification of areas in need of additional landslide risk assessment and authorizes regional partnerships to coordinate landslide monitoring efforts. It also authorizes the USGS to consult with institutions of higher education when establishing priorities for grants and implementing the debris flow early warning system.

Additionally, the bill reauthorizes the USGS’s 3D Elevation Program through FY2030 and requires relevant federal agencies to integrate enhanced elevation data. It also requires the National Oceanic and Atmospheric Administration’s precipitation frequency estimates to include precipitation from hurricanes, atmospheric rivers, and extreme precipitation events.
