I-5 Freight Corridor Project LOS ANGELES COUNTY, CALIFORNIA DISTRICT 7 – LA – 5 (PM 27.0/R67.0) 34210/0717000244 Initial Study with Proposed Negative Declaration / Environmental Assessment Prepared by the State of California Department of Transportation The environmental review, consultation, and any other actions required by applicable Federal environmental laws for this project are being, or have been, carried out by Caltrans pursuant to 23 USC 327 and the Memorandum of Understanding dated December 23, 2016 and executed by FHWA and Caltrans. January 2019 THIS PAGE INTENTIONALLY LEFT BLANK THIS PAGE INTENTIONALLY LEFT BLANK PROPOSED NEGATIVE DECLARATION Pursuant to: Division 13, Public Resources Code Project Description The California Department of Transportation (Caltrans) proposes the I-5 Freight Corridor Improvement Project to improve freight efficiency along Interstate 5 (I-5) from State Route 134 (SR-134) to Templin Highway Undercrossing in Los Angeles County. The project proposes to increase the vertical clearance to 16’-6”, to eliminate load capacity restrictions for heavy loads, and to reduce the frequency of route closures due to maintenance. Determination This proposed Negative Declaration (ND) is included to give notice to interested agencies and the public that it is Caltrans’ intent to adopt a ND for this project. This does not mean that the Caltrans’ decision regarding the project is final. This ND is subject to change based on comments received by interested agencies and the public. Caltrans has prepared an Initial Study for this project, and pending public review, expects to determine from this study that the proposed project would not have a significant effect on the environment for the following reasons: The proposed project would have no effect on agriculture and forest resources, mineral resources, and population and housing. In addition, the proposed project would have less than significant effects on aesthetics, air quality, biological resources, cultural resources, geology and soils, hazards and hazardous materials, hydrology and water quality, land use and planning, noise, public services, recreation, transportation/traffic, tribal cultural resources, and utilities and service systems.
