West Santa Ana Branch Transit Corridor The West Santa Ana Branch Transit Corridor is a proposed light rail project in Los Angeles County, California and Orange County, California intended to connect portions of downtown Los Angeles, Commerce, California, South Gate, California, Bellflower, California, Cerritos, California, Artesia, California, and Garden Grove, California. The project is developed by the Los Angeles County Metropolitan Transportation Authority in coordination with the Southern California Association of Governments, Orange County Transportation Authority, and local municipalities to extend regional transit access and link to existing systems such as the A Line (Los Angeles Metro), C Line (Los Angeles Metro), and planned West Santa Ana Branch (project)-related corridors.

Overview

The corridor follows the historic right-of-way of the former Pacific Electric Railway West Santa Ana Branch and aims to provide a north–south light rail connection between Union Station (Los Angeles), Norwalk/Santa Fe Springs station, and Garden Grove. The initiative appears in regional plans like the Measure M (Los Angeles County), Measure R (Los Angeles County), and the 2016 Long Range Transportation Plan administered by the Metropolitan Transportation Authority (Los Angeles). The project is part of broader transit investments tying into networks such as the Metrolink commuter rail, LA Metro Rail lines, and municipal bus operators including the Long Beach Transit and Orange County Transportation Authority services.

Route and Stations

Proposed alignments run from near the A Line (Los Angeles Metro) corridor through southeast Los Angeles County cities including Huntington Park, California, Bell, Bellflower, California, and Cerritos, California before entering northern Orange County neighborhoods in La Habra, California, Fullerton, California, and terminating in Garden Grove, California. Station candidates include connections at major nodes like Norwalk/Santa Fe Springs station, intermodal transfer points with Metrolink (Southern California), and downtown access to Union Station (Los Angeles). Design studies consider transit-oriented development near stations, activating parcels adjacent to landmarks such as Heritage Park (Bellflower), Cerritos Towne Center, and districts influenced by projects like Downtown Anaheim Plan.

History and Planning

The alignment revives the defunct Pacific Electric Railway service that once linked southeast Los Angeles to Long Beach, California and Santa Ana, California. Early preservation and planning discussions involved entities like the Southern California Regional Rail Authority and civic groups in Bellflower, California and Cerritos, California. Funding and prioritization were shaped by voter-approved ballot measures including Measure M (Los Angeles County), while environmental review processes invoked laws such as the National Environmental Policy Act and California Environmental Quality Act. Coordination across agencies mirrored precedents set by projects like the Gold Line (Los Angeles Metro), Expo Line, and the Regional Connector Transit Project.

Design and Construction

Engineering alternatives examined at-grade, elevated, and partially tunneled alignments to negotiate constraints near infrastructure owned by Union Pacific Railroad and crossings of highways including Interstate 5, Interstate 605, and State Route 91. Station architecture proposals referenced transit station designs used on the A Line (Los Angeles Metro) and standards by the American Public Transportation Association and consulting firms engaged by Metro. Construction phasing contemplates procurement models such as design-bid-build or design-build, with potential contractors comparable to firms that delivered sections of the Crenshaw/LAX Line and Regional Connector. Utility relocation, soil remediation, and seismic design follow California standards applied in projects like the Los Angeles River revitalization efforts.

Operations and Service Plans

Planners project light rail vehicle operations compatible with Kinki Sharyo or Siemens Mobility rolling stock used elsewhere on LA Metro Rail, with service frequencies targeted to match peak-period ridership patterns observed on the Blue Line (Los Angeles Metro). Service integration includes timed transfers with Metrolink Orange County Line, schedule coordination with OCTA bus routes, and fare policy alignment via the Tap card system. Operations oversight would involve LA Metro Rail Operations divisions, and workforce considerations reference labor agreements seen in negotiations with unions such as the Transport Workers Union of America and SEIU Local 721.

Environmental and Community Impact

Environmental studies assess impacts on wetlands, air quality, and noise consistent with precedents from the Century Freeway (I-105) mitigation projects and the San Gabriel River habitat restoration dialogues. Community engagement has involved neighborhood councils, chambers such as the Bellflower Chamber of Commerce, historic societies preserving Pacific Electric Railway heritage, and stakeholders from institutions like California State University, Long Beach and local school districts. Equity analyses reference criteria used by the California Air Resources Board and the Metropolitan Transportation Authority (Los Angeles) to evaluate benefits for communities historically underserved by transit. Mitigation measures consider bicycle and pedestrian improvements similar to those implemented along the Riverwalk (Long Beach) and station-area green infrastructure exemplified by the Los Angeles River Greenway.

Funding and Governance

Capital funding sources include allocations from ballot measures Measure M (Los Angeles County), federal grants administered by the Federal Transit Administration, state transit funds such as those managed by the California Transportation Commission, and local contributions from cities along the corridor. Governance involves interagency agreements among the Los Angeles County Metropolitan Transportation Authority, Orange County Transportation Authority, and municipal governments, following collaborative frameworks seen in projects like the Crenshaw/LAX Line and the Regional Connector Transit Project. Ongoing oversight will likely convene technical advisory committees, community advisory groups, and elected boards including the Los Angeles County Board of Supervisors and city councils from corridor cities.
