FHWA Climate Resilience Pilot Program: Arizona Department of Transportation
Arizona Department of Transportation conducted a pilot study to identify hotspots where highways are vulnerable to extreme weather, including high temperatures, drought, and intense storms. These factors can contribute to dust storms, wildfire, and flash floods, depending on the surrounding vegetation and landscape. The risks are different in the lower desert and grassland areas than in the forested mountain portions of the state. Understanding the risks and identifying vulnerable sections of roads will help ADOT plan to spend its construction and maintenance dollars more efficiently while improving public safety and ensuring continued services.
