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

Proposed Background
5
Project Location
6
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
Project Purpose
Reduce flood risk to
properties in RD 784 and
TRLIA assessment districts
by providing sustainable
200-year flood protection.

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.
9
Proposed Project Alternatives
10
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
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

Alternatives 1, 2, and 3
200-Year Embankment in Goldfields
Source: TRLIA 2013, adapted by AECOM in 2014
• 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

Alternative 3
Relocation of Waterway 13
Fish barrier at New Outlet
Scour Protection

• Will require periodic repair and replacement.
• Expected design life of 50 years.
15
Alternative 4
200-Year Levee South of Goldfields
Source: TRLIA 2013, adapted by AECOM in 2014
• 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
16
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
CEQA Review Process
18
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
