Introduction In conformance with the National Environmental Policy Act of 1969, 42 U. S. C. Section 4431 et seq. (NEPA), as amended, and the California Environmental Quality Act (CEQA), California Public Resources Code, Section 21000 et seq, the Bureau of Reclamation (Reclamation) and the City of Sacramento (City) have prepared this Environmental Assessment/Initial Study (EA/IS), in association with the Sacramento Area Water Forum (Water Forum), to evaluate and disclose potential environmental impacts associated with implementation of the Lower American River (LAR) Anadromous Fish Habitat Restoration Project (Proposed Action or proposed project) over a 16-year period from 2019 through 2034. The City has also prepared a Notice of Intent to Adopt a Mitigated Negative Declaration (MND), a CEQA Environmental Checklist, and a proposed MND, as required by the CEQA Guidelines. Reclamation is the NEPA lead agency and the City is the CEQA lead agency for the Proposed Action. CEQA review is required because the 16-year long Proposed Action will be physically implemented by the City, using City equipment and employee labor, in association with the Water Forum, and may result in a potentially significant impact on the environment that must be analyzed. This EA/IS describes the existing environmental resources in the project area; evaluates the impacts of the No Action Alternative and the Proposed Action on the resources; and proposes measures to avoid, minimize, or mitigate any significant adverse impacts. This EA/IS was prepared in accordance with NEPA, Council on Environmental Quality (CEQ) regulations (40 Code of Federal Regulations [CFR] 1500-1508), Department of the Interior Regulations (43 CFR Part 46), and State CEQA Guidelines (Title 14, Section 15000 et seq. of the California Code of Regulations [CCR]). Reclamation’s 2016 EA (Reclamation 2016) is incorporated by reference in its entirety, as well as Reclamation’s 2008 EA (Reclamation
