Improving Southern California's Air Quality, Mobility, and Traffic Safety
I-710 Corridor EIR/EIS | Los Angeles County, CA
LSA is leading the environmental team preparing the Environmental Impact Report/Environmental Impact Statement (EIR/EIS) for the Interstate 710 (I-710) Corridor Project in Los Angeles County. The project proposes to improve I‑710 in Los Angeles County from Ocean Boulevard in the City of Long Beach to State Route 60 (SR-60), a distance of approximately 18 miles. The purpose of the project is to improve air quality, mobility, and traffic safety, as well as accommodate growth in goods movement within the I-710 Corridor. Primary issues of concern include air quality/public health, community impacts, environmental justice, and traffic safety. The project alternatives include innovative strategies such as zero-emissions truck technology. In addition to preparing the EIR/EIS, LSA prepared several technical studies, including a comprehensive Community Impact Assessment, a Historic Property Survey Report, a Paleontological Identification/Evaluation Report, a Natural Environment Study, and a Section 4(f) Evaluation. A Recirculated Draft EIR/Supplemental Draft EIS is being prepared to evaluate a revised set of alternatives.
The project is a model for multi-agency coordination and collaboration, with the California Department of Transportation District 7 (Lead Agency for the California Environmental Quality Act/National Environmental Policy Act [CEQA/NEPA]) and the Los Angeles County Metropolitan Transportation Authority (contracting agency) working closely with the other agencies that have partnered to fund the EIR/EIS effort, including the Gateway Cities Council of Governments, the Port of Long Beach, the Port of Los Angeles, the Southern California Association of Governments, and the Interstate 5 (I-5) Joint Powers Authority.
