The Orange County Transportation Authority (OCTA) board of directors voted on Monday to advance four projects under the Coastal Rail Stabilization Priority Project.
“This rail line is essential to safely moving passengers and freight, and I’m proud of the work we are doing with strong input from the community and all stakeholders to make sure this vital corridor remains operating smoothly,” Doug Chaffee, OCTA chairman and Orange County fourth district supervisor, said.
A series of bluff failures and landslides since 2021 in addition to coastal erosion have significantly impacted the Los Angeles–San Diego–San Luis Obispo Rail Corridor’s operations. OCTA secured $305 million in state and federal funding last year for the project.
The approved projects are in the environmental and preliminary engineering phase.
Reinforcement Area 3 is a proposed catchment wall at Mariposa Point to protect the area from landslides. The alternative analysis will be finalized this month, and preliminary engineering and environmental documentation will be completed later this year.
Reinforcement Areas 1, 2, and 4 are multiple protective measures including engineered revetments, sand nourishment to address coastal erosion risks, seawalls, and riprap repair.
The alternatives analysis process will concluded by mid year, and preliminary engineering and environmental documentation will be completed in late 2026.
