National Landslide Preparedness Act Reauthorization Act of 2025
Sponsored By: Representative DelBene
In Committee
Summary
Brings atmospheric rivers and extreme-precipitation risks into national landslide and flood preparedness. This bill would reauthorize and broaden the National Landslide Preparedness framework to add new hazard definitions, expand data and partners, and improve monitoring and early warning systems.
Show full summary
- Communities and emergency responders: Strengthens debris-flow and landslide early warning and emergency response planning. It directs better real-time risk management for risks from changing hydrology, thawing permafrost, geologic activity, and data-poor areas.
- Tribal, Native Hawaiian, and academic partners: Expands who can join regional partnerships and who is eligible for grants by adding Tribal organizations, Native Hawaiian organizations, and institutions of higher education.
- Federal data, coordination, and funding: Requires flood and landslide strategies and databases to include atmospheric river and extreme precipitation risks, adds NASA to the coordinating committee, extends program authorization to 2030, and raises the U.S. Geological Survey authorization to support program work.
*Would increase federal spending authorization for USGS landslide programs to $35.0 million, including at least $10.0 million for landslide early warning systems.*

Bill Overview
Analyzed Economic Effects
5 provisions identified: 4 benefits, 0 costs, 1 mixed.
Better mapping data and NASA coordination
The bill would extend the 3D Elevation Program to 2030. Agencies would acquire, process, and integrate 3D elevation data and related derivative products. A 3D Hydrography working group would join the federal mapping team. NASA’s Administrator would join the landslide coordinating committee to strengthen satellite and remote-sensing support.
Funding boost for landslide warning systems
The bill would direct $35 million to the U.S. Geological Survey for landslide work through 2030. At least $10 million would buy, deploy, and repair early warning systems in high-risk areas. This could improve alerts and response in places with frequent slides.
More local and Tribal partners in landslide work
This bill would let more groups join landslide work and grants. It would add Tribal organizations, Native Hawaiian organizations, and some colleges as eligible partners. The Secretary would set up regional partnerships, starting in Alaska, as soon as practicable. Partners would need landslide mapping or monitoring skills. Regions with recent deadly landslides could get extra award consideration.
Plans and maps would include atmospheric rivers
The bill would add clear definitions for "atmospheric river," "atmospheric river flooding event," and "extreme precipitation event." Extreme precipitation would mean rain or snow above a 5-year level for that place. The Secretary of Commerce would decide when some flooding events are of particular concern. The next national landslide strategy would need a risk report on these events, done with the Secretary of Commerce. The hazards database would flag areas at risk from hydrology changes, these weather events, quakes, volcanoes, tsunamis, or poor data.
Program focus shifts to sharing info
The bill would shift program wording from "implement" to "disseminate." It would change the purpose to "contribute to protecting," not simply "protect." This could mean more focus on sharing data and less on direct on-the-ground actions.
