LA's Coastal Rail Gets $2.5M Climate Resilience Study
OCTA approves study to protect 12-mile coastal rail corridor from sea level rise
OCTA Starts $2.5M Coastal Rail Study
Orange County commuters who rely on coastal rail service will see infrastructure improvements in coming years as officials work to protect tracks from rising seas and erosion. The Orange County Transportation Authority's Board of Directors approved a $2.5 million coastal rail resiliency study on January 8, transit officials said. The study examines 12 miles of vulnerable coastal rail corridor that carries Metrolink trains through Orange County communities.
Climate Threats Drive Planning
The study addresses growing concerns about sea level rise and coastal erosion threatening critical rail infrastructure along Southern California's coast. California's Ocean Protection Council projects between one and seven feet of sea level rise by 2100 along the region's coastline, according to state climate data. Officials said the assessment will identify specific vulnerabilities and develop protection strategies for the corridor. The agency hasn't released a timeline for when the study will be completed or when recommended improvements might begin.
Study Examines 12-Mile Corridor
The $2.5 million study focuses on coastal rail infrastructure used by Metrolink's Pacific Surfliner route, which carried approximately 2.8 million passengers annually before the pandemic. Officials said the assessment will examine threats from sea level rise, storm surge, and coastal erosion along the 12-mile corridor. Specific technical methodologies and consultant firms conducting the study weren't available by publication time. The agency said findings will guide future infrastructure investments to protect the rail line from climate impacts.
Implementation Timeline Unclear
OCTA announced the study approval in a January 9 press release but didn't provide a specific completion date for the assessment. Officials said they'll release more details about implementation timelines once study findings are available. Cost estimates for recommended infrastructure improvements will be determined based on study results, according to the transit agency.
Regional Precedent Exists
The study follows similar efforts by other California coastal transit agencies facing climate threats. San Diego's regional transportation agency completed a coastal rail vulnerability assessment between 2020 and 2023, identifying $120 million in needed protective improvements. Dr. Patrick Barnard, a research geologist with the U.S. Geological Survey's Pacific Coastal and Marine Science Center, said coastal rail infrastructure in California faces significant threats from sea level rise and increased storm intensity. Riders can track service updates and route information through Moovit as the agency develops protection strategies for the coastal corridor.
