1 Scoping Meeting Yuba Goldfields 200-Year Flood Protection Project Environmental Impact Report June 23, 2014

2 Meeting Agenda Welcome and Introductions Meeting Objective Project Background Proposed Project Alternatives Scoping and CEQA Process Environmental Issues Public Comments and Input 2

3 Introductions Three Rivers Levee Improvement Authority Paul Brunner, Executive Director Downey Brand Andrea Clark, Legal Counsel MBK Engineers Larry Dacus, P.E., Project Engineer AECOM Andrea Shephard, Ph.D., Environmental Project Manager 3

4 Meeting Objective Seek public and agency input on the scope and content of the EIR, including alternatives 4

5 Proposed Background 5

6 Project Location 6

7 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. 7

8 Project Purpose 8 Reduce flood risk to properties in RD 784 and TRLIA assessment districts by providing sustainable 200-year flood protection.

9 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 Minimize impacts on aggregate mining operations. Minimize impacts on gold dredging operations. Minimize impacts on environmental resources. Provide environmental benefits, if feasible. 9

10 Proposed Project Alternatives 10

11 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. 11

12 Project Alternatives Alternative 1:100-Year Project Enlargement 9.0 mile embankment 331 acres in Goldfields Alternative 2:West-Side Goldfields Boundary Alignment 8.8 mile embankment 317 acres in Goldfields Alternative 3:South Bank Yuba River Alignment 9.1 mile embankment 291 acres in Goldfields Alternative 4:Levee South of the Goldfields 3.5 mile embankment 199 acres in Goldfields 12

13 13 Project Alternatives

14 14 Alternatives 1, 2, and Year Embankment in Goldfields Regular O&M: inspections, weed abatement, surface patrol road maintenance. During High Flow Periods: Surface road patrols every 4 hours to identify/address potential flooding issues

15 Alternative 3 Relocation of Waterway Fish barrier at New OutletScour Protection Will require periodic repair and replacement. Expected design life of 50 years.

16 16 Alternative Year Levee South of Goldfields Regular O&M: Same as other alternatives plus management of vegetative cover on levee side slopes, operation and annual maintenance of pipe and gates at YCWA canal crossing. During High Flow Periods: Surface road patrols every 4 hours to identify/address potential flooding issues

17 No-Project Alternative 200-year flood protection solution not built. 100-year flood protection solution built. Decreased flood inundation benefits of TRLIA 200-Year Flood Protection Program. Portions of RD 784 and TRLIA assessment districts may be mapped into FEMA floodplains. Residents have to purchase flood insurance. 17

18 CEQA Review Process 18

19 Purpose of Scoping Inform public and agencies Receive public/agency input Help define project Help identify range of alternatives Help identify environmental effects to be evaluated 19
