Caltrans Statewide Vulnerability Assessments



California Department of Transportation (Caltrans)




Caltrans has completed the statewide Climate Change Vulnerability Assessments that identify segments of the State Highway System vulnerable to climate change impacts including precipitation, temperature, wildfire, storm surge, and sea level rise. The climate change data was developed in coordination with climate change scientists and experts at Federal, State, and regional organizations at the forefront of climate science. The results of the Climate Change Vulnerability Assessments will be used to guide analysis of at-risk assets and develop adaptation plans to reduce the likelihood of damage to the State Highway System, thereby allowing Caltrans to both reduce the costs of climate impacts, and to enhance the resiliency of the multi-modal transportation system for all users.
