Coastal Rail Emergency Projects
Coastal Rail Emergency Project – Areas 1 and 2
These areas were completed in June 2025.
Project Overview
OCTA and Metrolink strategically placed large boulders, also known as riprap, between North Beach and Mariposa Point to protect the tracks. Approximately 5,900 tons of riprap were installed within the same riprap footprint. The quantity was more than 1,700 tons less than the original construction estimate of 7,650 tons. This reduction was achieved through efficient use and reorganization of existing riprap, allowing the project team to reinforce the track using less new material while still meeting safety and stabilization goals.
The remaining spans of the San Clemente Pedestrian Beach Trail were also removed. The Beach Trail is being reconstructed as part of Area 3 construction.
