Hazards_Exposure

The BETA - Hazard Exposure: National Highway System dataset was updated on October 16, 2025 from the Bureau of Transportation Statistics (BTS) and is part of the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). Dataset subset to Thrive Study Region on 10/30/2025. The BETA - Hazard Exposure: National Highway System dataset shows the exposure of North America's roadway system to select natural hazards. The dataset combines hazard data from FEMA, USGS, NOAA, and USDA with information for the National Highway System (NHS) dataset -- comprising roadways important to the nation's economy, defense, and mobility -- from the U.S. Department of Transportation (USDOT)/Bureau of Transportation Statistics (BTS) National Transportation Atlas Database (NTAD). Hazard data include estimates of annualized frequency of Coastal Flooding, Cold Wave, Drought, Hail, Hurricane, Heat Wave, Ice Storm, Lightning, Strong Wind, Tornado, and Winter Weather from the FEMA National Risk Index. Landslide Index and Sinkhole Susceptibility derive from USGS models. USDA Burn Probability data underlie estimates of wildfire exposure. NOAA SLOSH models estimate storm surge inundation from hurricanes. The data set covers all 50 states of the United States, the District of Columbia, and Puerto Rico.
