Draft EA four Bridges System Project + Appendices 2 Sep. 2020

This Environmental Assessment (EA) has been prepared to analyze potential impacts from the proposed Repair Four Bridges System Project over Dry Creek and Best Slough on Beale Air Force Base (AFB), California. Dry Creek, a tributary to the Bear River, flows for approximately 19 miles southwest from its headwaters in Nevada County, California. Dry Creek flows onto Beale AFB in Yuba County, where it becomes a braided channel and develops into sections known as Dry Creek and Best Slough. Dry Creek ends where it joins the Bear River near the city of Rio Oso. Best Slough is confined by a levy along State Route 65 near the community of Plumas Lake, California. It is
directed south unnaturally into the Bear River west and downstream of the natural Dry Creek-Bear River Confluence.

This document has been prepared in accordance with the National Environmental Policy Act (NEPA) of 1969, as amended (42 United States Code (U.S.C.) 4321 et seq.); the Council on Environmental Quality (CEQ) regulations implementing the procedural provisions of NEPA, 40 Code of Federal Regulations (CFR) Parts 1500−1508; and United States Air Force (USAF) policy and procedures (32 CFR Part 989).
