Redefining Project Alternatives in Light of New Information

Careful review of the latest traffic data and new information gathered during the public review of the Draft EIR/EIS has prompted further evaluation of the Alternatives for the I-710 Corridor Project. Preliminary findings suggest that traffic patterns are different than identified in the DEIR/EIS. In addition, there is a clearer understanding of the origin and destination of truck traffic within and beyond the project area. Another factor affecting the project build alternatives includes physical constraints on the design and location of access points to/from the I-710 along the project area. Over the next few months, the project team will work closely with the advisory committees and I-710 corridor community to revise the alternatives to best meet the needs of the project.

Supplemental I-710 Technical Memos Released

At the previous Corridor Advisory Committee meeting in August, the project team received questions regarding traffic and growth assumptions guiding the RDEIR/SDEIS effort. Please find below links to two memos which respond to questions pertaining to Port cargo forecasts and travel forecasting input data used in the RDEIR/SDEIS as it relates to the SCAG 2012 RTP.

I-710 Corridor Project Reaches New Milestone

Draft EIR/EIS Headed for Recirculation
The I-710 Corridor Project is aimed at developing solutions to improve air quality and public health, safety, and the design of the existing freeway. This project includes an extensive community participation process made up of several tiers of advisory committees and groups. The committees and groups have worked tirelessly and provided invaluable feedback on the project.

Upon review of the extensive feedback received during the Draft EIR/EIS public comment period, Metro, Caltrans, and the project Funding Partners decided in March 2013 to move forward with a Recirculated DEIR/Supplemental DEIS (RDEIR/SDEIS). This focused RDEIR/SDEIS will update the draft environmental document for the no-build alternative and build alternatives. It is anticipated that the RDEIR/SDEIS will be released for public review and comment in late 2016.

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. Thank you for your interest.  

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.

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, the I-710 Freeway experiences serious congestion and safety issues. 

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.

Metro and six project participants are now conducting an Environmental Impact Statement/Environmental Impact Report (EIR/EIS) to analyze the range of possible improvement alternatives for the I-710 corridor. The I-710 Corridor Project EIR/EIS will study 18 miles of the I-710 Freeway between the Ports of Long Beach and Los Angeles and the Pomona Freeway (SR-60).

The study area encompasses 15 cities and unincorporated areas in Los Angeles County adjacent to the freeway corridor. Study Area Map.

The EIR/EIS, a study required by federal and state statutes, is an assessment of the likely influences that future improvements may have on the environment and communities along the corridor. It includes analyses of ways to reduce or avoid possible adverse environmental impacts.

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 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 Status

Updates to relevant corridor and regional data, as well as new information gleaned during the public comment period, resulted in a decision made by the agencies to recirculate the environmental document. The project team will continue to work with the community between now and Spring 2014 to refine the alternatives that will be included in the recirculated DEIR/SEIS.

Project Schedule

The project team anticipates that a set of redefined Alternatives for potential inclusion in the recirculated DEIR/SEIS will be identified by Spring/Summer 2014. The revised schedule is noted below and is subject to change:

  • Complete preliminary design and traffic forecasts for use in updated studies (July 2014)
  • Complete updated engineering and environmental studies of alternatives (Early 2015)
  • Circulate RDEIR/SDEIS for public review (Early 2016)
  • Identify Preferred Alternative (Mid 2016)
  • Complete Final EIR/EIS (Early 2017)
  • Project Approval/Record of Decision (Early 2017)
