Today Metro’s Planning and Programming Committee approved four specific West Santa Ana Branch light rail alignments to be used for environmental studies.

The West Santa Ana Branch is a historic Pacific Electric Streetcar right-of-way that runs diagonally through southeast L.A. County cities including Paramount, Bellflower and Artesia. Measure M includes funding for two phases of light rail on the West Santa Ana Branch, with the line ultimately expected to run from Union Station to the city of Artesia.

In September 2016, the Metro board approved a four-year $12 million contract with Parsons Brinckerhoff to complete environmental clearance work for the line. The environmental clearance studies follow several earlier preliminary studies by the Southern California Association of Governments and Metro.

The southern portion of the line runs on a very clear off-street rail right-of-way. The alignment for the northern portion, connecting to Union Station, has not been finalized. With various options including extensive aerial tracks and subway tunnels, the northern portion looks like it will be relatively expensive.

Today, the committee approved further study on four alignments for the northern portion of the line, two along the Pacific Boulevard corridor, two along the Alameda Street/Blue Line corridor. Metro labels the alignments as follows:

  1. Pacific Boulevard/Alameda Street
  2. Pacific Boulevard/Vignes Street
  3. Alameda Street
  4. Alameda Street/Vignes Street

The four alignments are mapped below.

Metro plans to scope their Environmental Impact Report this spring, then prepare the full EIR, which the agency expects to approve in late 2019.

New Concept Considered For Union Station Re-Vamp: Above-Grade Concourse

|
The estimated $2.75 billion LinkUS project is planned to convert Union Station from a stub-end station to a run-through station. Run-through tracks would decrease delays, increase capacity, and get Union Station ready for future West Santa Ana Branch light rail and California high-speed rail. LinkUS would significantly expand today’s current underground concourse hallway that riders use […]
