Serra Siding Extension Project

Serra Siding Extension Project

The proposed Project involves the construction of new rail infrastructure within existing railroad ROW, owned by the Orange County Transportation Authority (OCTA). The proposed Project would replace the existing single track within the Project alignment and extend the existing Serra siding south between MP 199.80 and CP Doheny at MP 201.00. Under the proposed Project, the proposed main track and siding would run parallel to each other, 15 feet apart, except where the main track and siding pass above the PCH (i.e., at Bridge 2), where they would run further apart. The existing single-track single-span bridge structure over the PCH would be demolished and replaced by the two new single-track single-span bridge structures. Additionally, the track profiles would be raised where the main tracks and siding tracks cross over PCH to provide additional vertical clearance for vehicular traffic beneath the bridge, per California Department of Transportation (Caltrans) standards and specifications for expressways. The existing CP Serra at MP 199.90 would be retired, and a new intermediate signal would be installed in its place at MP 199.70. At the eastern end of the siding extension, a new CP (CP Doheny) would be added at MP 201.00. An existing at grade crossing south of the Project alignment, located at MP 201.00, where Palisades Drive and Beach Road meet at the PCH, would be unaffected by the Project. Multiple above and underground utilities and drainage facilities within the railroad corridor would be relocated, extended, and/or protected in place as part of the Project. New retaining walls, totaling approximately 1,200 linear feet and ranging from 4 to 15 feet in height, would also be constructed along the Project alignment, where required. Project construction is expected to begin in 2024 and would continue for up to 24 months. Project construction would largely occur within OCTA/SCRRA ROW. Construction staging area locations would be situated adjacent to the OCTA/SCRRA corridor to the greatest extent feasible. Once constructed, the proposed Project would improve safety and reliability within the corridor and would also create additional train capacity with the goal of improving passenger train operations and on time performance for both Metrolink’s Orange County and Inland Empire Orange County Lines.
