Climate Adaptation Planning

Overview

Climate Adaptation Planning

The geographically and climatologically diverse Sacramento region faces a range of climate-related threats. Increasing extreme heat poses maintenance and operational issues for roadways, bridges and railways, particularly in the lower lying portions of the region. Wildfires and landslides present risks to the transportation system in the higher elevation areas. Higher extreme and average precipitation levels and changing snowmelt patterns could increase flooding and erosion on roadways in both the more mountainous areas and in downstream drainage basins. Sea level rise and storm surge pose risks to the Delta communities and transportation system serving them.

The region’s communities vary in size, demographics, and capacity to address climate threats. Through climate adaptation planning work, SACOG aims to help its members navigate these risks and establish a more resilient transportation network.

Vulnerability and Criticality Assessment

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.
