I-710 Corridor Project

The Long Beach Freeway (I-710) is a vital transportation artery, linking the ports of Long Beach and Los Angeles to major Southern California distribution centers and intermodal rail facilities. An essential component of the regional, statewide and national transportation system, it serves both passenger and goods movement vehicles. The I-710 Freeway experiences serious congestion and safety issues as a result of population growth, increased cargo container volume at the ports of Los Angeles and Long Beach, increasing traffic volumes, and an aging infrastructure.

In March 2005, following an extensive technical and community participation process, Metro completed the I-710 Freeway Major Corridor Study (MCS). The study analyzed congestion and mobility along the corridor in order to develop transportation solutions that preserve and enhance the quality of life of surrounding neighborhoods and communities.

Environmental Impact Report/Environmental Impact Statement (EIR/EIS)

For a proposed project to move forward to construction, the extent of environmental impacts must first be determined according to State of California law, through the California Environmental Quality Act (CEQA), and the federal National Environmental Policy Act (NEPA). If potentially significant impacts are anticipated, or if the project is considered controversial, an EIR/EIS is required. The EIR/EIS process simultaneously ensures that the requirements for documenting and reducing environmental impacts of a project are met. Additionally, the process provides for technical analysis as well as public input and participation. It provides the information needed to make a decision regarding the Preferred Alternative for a project.

Draft EIR/EIS Headed for Recirculation

In 2012, a draft EIR/EIS was conducted for the I-710 Corridor Project to identify a Preferred Alternative for the project. Careful review of the latest traffic data, which indicated different traffic patterns than originally identified, and new information gathered during the public review of the Draft EIR/EIS, including a clearer understanding of the origin and destination of truck traffic within and beyond the project area, has prompted further evaluation of the Alternatives for the I-710 Corridor Project.

As a result of this new data and information, Metro and six project participants (see below) decided in March 2013 to release a Recirculated Draft Environmental Impact Report/ Supplemental Draft Environmental Impact Study (RDEIR/SDEIS) to analyze the range of possible improvement alternatives for the I-710 corridor. The I-710 Corridor Project RDEIR/SEIS will study 18 miles ( Study Area Map ) of the I-710 Freeway between the Ports of Long Beach and Los Angeles and the Pomona Freeway (SR-60), encompassing 15 cities and unincorporated areas in Los Angeles County adjacent to the freeway corridor. This focused RDEIR/SDEIS will update the draft environmental document for the no-build alternative and build alternatives: Alternative 5C and 7 . The Project Team is now working on the technical studies that constitute the basis of the environmental document, and it is anticipated that the RDEIR/SDEIS will be released for public review and comment in Spring 2017.

Project Participants

Metro is joined by several partner agencies in completing the I-710 Corridor Project EIR/EIS. These agency partners include the California Department of Transportation , the Gateway Cities Council of Governments , the I-5 Consortium Cities Joint Powers Authority, the Port of Long Beach , the Port of Los Angeles , and the Southern California Association of Governments .
Project Objectives
Metro’s objectives for the I-710 Corridor Project EIR/EIS are shaped by priorities identified by stakeholders along the I-710 corridor during and following the MCS effort. These objectives include developing transportation alternatives that will:

  • Improve air quality
  • Improve mobility, congestion and safety
  • Assess alternative, green goods movement technologies

Community Participation

The I-710 Corridor Project EIR/EIS seeks to break new ground in not only identifying impacts and mitigation strategies but in engaging community members and stakeholders in developing strategies to improve air quality, mobility, and quality of life.

Through a representative community advisory committee structure, outreach activities are designed to provide stakeholders the opportunity to work hand-in-hand with the technical team throughout the life of the project. Community participation for the I-710 Corridor Project EIR/EIS is modeled on the highly regarded program used to complete the MCS.
The project team continues to work closely with the advisory committees to provide progress updates and receive feedback from the community. To learn more about the project, please review the information and resources tabs on this website. If you have any questions or comments, please visit the “Contact Us” section on the website for e-mail, regular mail, project hotline, and comment form details.

The public is invited to stay involved by:

  • Attending regular advisory committee meetings.
  • Participating in community forums.
  • Submitting comments and questions via web or phone.
  • Joining the project mailing list.

Project Schedule

The revised schedule is noted below and is subject to change:

  • Complete preliminary design and traffic forecasts for use in updated studies (Spring 2016)
  • Complete updated engineering and environmental studies of alternatives (Fall 2016)
  • Circulate RDEIR/SDEIS for public review (Spring 2017)
  • Identify Preferred Alternative (Mid 2017)
  • Complete Final EIR/EIS (Late 2017)
  • Project Approval/Record of Decision (Early 2018)

Please visit this website on a regular basis to stay informed of the latest updates.

Public involvement is critical to the success of the I-710 Corridor Project EIR/EIS. You are encouraged to attend meetings and events to provide your feedback and suggestions on the topics being discussed.
