Abstract: The Marysville Ring Levee was originally part of the 1999 Yuba River Basin Project, which included five miles of levee modifications along the MRL to address under-seepage. Since authorization, design refinements have been proposed due to improved information indicating significant geotechnical concerns, including levee under-seepage and through-seepage in the MRL. This EA/IS describes the design refinements and evaluates the effects of the proposed action. This Environmental Assessment/Initial Study 1) describes the existing environmental resources in the project area; 2) evaluates the effects and significance of the proposed action on the resources; and, 3) proposes measures to avoid, minimize, or mitigate any adverse effects to a less-than-significant level. This EA/IS is in compliance with the National Environmental Policy Act and the California Environmental Quality Act, and provides full disclosure of the effects of the proposed action.
