Mendocino State Route 128 Flood and Feasibility Study

Caltrans seeks a consultant to perform a feasibility study to develop and evaluate strategies to address a flood-prone portion of State Route 128 in Mendocino County. The study area is regularly impacted by the effects of sea level rise (SLR), storm surge, and riverine flooding. Heavy rainfall and flooding have caused sinkholes, roadway slip-outs, landslides, and damaged guardrails. The goal of the study is to determine how best to prevent future flooding, improve access along SR 128, and reduce vulnerability of Caltrans assets to existing and future climate stressors.
