National Landslide Preparedness Act Reauthorization Act of 2025
Summary
What This Bill Does
The National Landslide Preparedness Act Reauthorization Act of 2025 reauthorizes and expands federal landslide, flood, drought, and water-observation work. It adds definitions for atmospheric rivers, atmospheric-river flooding events, and extreme precipitation events, and folds those hazards into landslide-preparedness and flood-observation authorities.
The bill also creates the Next Generation Water Observing System inside the U.S. Geological Survey, broadens technical-assistance and partnership language, and expands groundwater and streamgage monitoring priorities.
Who Benefits and How
Communities facing landslide, flood, drought, atmospheric-river, snowpack, groundwater, and water-quality risks benefit from better monitoring data, forecasts, technical assistance, and hazard planning. Tribal governments, Native Hawaiian organizations, local governments, regional research partners, emergency managers, and water managers benefit from broader partnership eligibility.
Researchers and institutions of higher education benefit from explicit roles in landslide and water-observation work.
Who Bears the Burden and How
The Department of the Interior, U.S. Geological Survey, Department of Commerce, and NOAA must implement broader definitions, monitoring systems, coordination duties, and reporting priorities. Federal taxpayers fund the expanded hazard-preparedness and observing-system work.
Participating agencies and research partners must coordinate data, streamgage priorities, groundwater assessments, technical assistance, and regional partnerships.
Key Provisions
- Adds atmospheric-river, atmospheric-river flooding event, and extreme precipitation event definitions.
- Reauthorizes and expands National Landslide Preparedness Act definitions and eligible partners.
- Establishes the Next Generation Water Observing System within USGS.
- Requires real-time water quantity and quality data to support flood, drought, snowpack, evapotranspiration, groundwater, and glacier-risk modeling.
- Expands USGS water-data and groundwater-monitoring priorities, including permafrost thaw and precipitation changes.
