Final Initial Study with Proposed Mitigated Negative Declaration / Environmental Assessment with Finding of No Significant Impact (October 2015)

The California Department of Transportation (Caltrans), as assigned by the Federal Highway Administration (FHWA), has prepared this Initial Study/Environmental Assessment (IS/EA), which examines the potential environmental impacts of the alternatives being considered for the proposed project located in Orange County, California. Caltrans is the lead agency under the National Environmental Policy Act (NEPA), as designated by FHWA, and the lead agency under the California Environmental Quality Act (CEQA). The document tells you why the project is being proposed, alternatives that are being considered for the project, how the existing environment could be affected by the project, the potential impacts of each of the alternatives, and the proposed avoidance, minimization, and/or mitigation measures.
