Vulnerability and Criticality Assessment

Post

The 2020 Vulnerability and Criticality Assessment establishes a better understanding of extreme weather and climate change threats to the region’s transportation system. Expected changes in wildfire, riverine flooding, Delta sea level and surge, extreme heat, and other hazards pose significant risks to many portions of the regional transportation system and require rethinking of how transportation infrastructure is planned, engineered, and managed.

Building on SACOG’s 2015 adaptation plan, this assessment includes a more detailed analysis of which assets are most critical to the function of the region’s transportation network and which are most vulnerable to these hazards. This report describes the methodology, data sources, replicability of the analysis, and results of the systemwide assessment.
