Project Need
• Yuba River actively eroding south bank tailings mound.
• Landform changes in Goldfields have affected flow paths and made it easier for floodwaters to flow through the Goldfields.
• Areas that were thought to have 200-year flood protection are still at risk.

Project Objectives
• Prevent 200-yr flood waters from flowing through Goldfields and flanking State Plan of Flood Control levee system.
• Implement long term sustainable solution by 2025.
• Minimize impacts on aggregate mining operations.
• Minimize impacts on gold dredging operations.
• Minimize impacts on environmental resources.
• Provide environmental benefits, if feasible.

Project Alternatives
• Four (4) Action Alternatives plus the No-Project Alternative to be evaluated at equal level of detail in EIR.
• Alternatives 1, 2, and 3 – Construct embankment within the Goldfields using existing dredge tailings.
• Alternative 4 – Construct engineered levee south of the Goldfields using material imported from nearby.
• All alternatives would meet USACE and DWR urban levee design criteria for 200-year flood protection.
