National Landslide Preparedness Act Reauthorization Act of 2025

Key Points

• This bill extends the National Landslide Preparedness Act through 2030 and increases its yearly budget to $35 million. At least $10 million of that money must be used to buy, install, and fix early warning systems that alert people when a landslide is about to happen in high-risk areas.
• The government will now specifically study 'atmospheric rivers'—long, narrow regions in the atmosphere that carry moisture and cause heavy rain or snow. Experts will assess how these massive storms and other extreme weather events increase the risk of deadly landslides across the country.
• A new 'Next Generation Water Observing System' will be created to provide real-time data on water levels and quality. This system is designed to be more affordable and faster than older tools, helping officials predict floods and droughts more accurately in 10 initial regions.
• The program is expanding to include Native Hawaiian organizations and more Tribal groups in emergency planning. It also sets up regional partnerships with colleges and local experts to better map and monitor landslide risks in specific parts of the country where the danger is highest.
• The bill keeps the 3D Elevation Program running until 2034. This program uses advanced technology to create highly detailed 3D maps of the ground, which are essential for identifying which hillsides are unstable and likely to collapse during a storm.
