Overview


The goal of the Metro Eastside Extension Phase ll Project is to improve mobility in the region by connecting communities farther east of Los Angeles to Metro’s regional transit system. An approximately 9-mile extension of the current Metro E Line (formerly the L Gold Line) further east from its current terminus at Atlantic Boulevard in East Los Angeles will offer more access to the eastern area of LA County Communities in the project area, which includes the cities of Commerce, Montebello, Monterey Park, Pico Rivera, Rosemead, Santa Fe Springs, South El Monte, and Whittier, the unincorporated Los Angeles County communities in East Los Angeles, and West Whittier-Los Nietos.


The project is funded by Measure M, which allocates $6 billion to the Eastside Transit Corridor Phase ll Project to be programmed in two cycles. Cycle 1 identifies $3 billion with a 2029 groundbreaking date and an opening date of 2035. Cycle 2 identifies $3 billion with a 2053 groundbreaking date and an opening date of 2057.

Cordoba’s Role


Cordoba and HNTB formed Cordoba HNTB Design Partners, Inc., to conduct advanced conceptual engineering (ACE) and urban design services for this Metro extension. The team is responsible for all necessary data collection, coordination, field studies, and design work in direct support or parallel to the development and completion of a supplemental/recirculated draft environmental impact report (EIR) document and the subsequent final EIR as part of the CEQA requirements. The work includes refinement of the conceptual engineering plans and exhibits previously developed for the 2014 Draft EIS/EIR to a 15 percent level of engineering calculations. Cordoba coordinated work related to survey, utilities and traffic design in development of the ACE plans. It also included the ACE design for the build alternatives/options and coordinating regulatory approval from third party agencies while addressing specific design issues raised by key stakeholders and communities in the target area. The team provided support at local stakeholder and public community meetings for the project.


The evaluated three build alternatives, including the following:


• SR 60 North Side Design Variation (NSDV) alternative


• Washington Alternative with Atlantic Boulevard below-grade alternative


• Combined Alternative of SR 60 and Washington alternatives


In December 2022, the Metro Board selected the Washington Alternative as the locally preferred alternative (LPA) to be further analyzed in the Final EIR.
