Central Valley Flood Protection PlanPrimary Goal of CVFPP: Improve Flood Risk Management

Implementation of structural and nonstructural actions for protecting urban areas and lands of Sacramento and San Joaquin river basins, and the Delta

System‐wide investment approach

Purpose of the RFMPBuild upon the CVFPP by describing 

regional flood management challenges and deficiencies, identifying solution 

strategies and projects, setting priorities, and developing a local financing plan for their implementation which leverages 

local, State, and federal funding opportunities.

Solution Strategies and Management Actions

State Systemwide Investment Approach (SSIA) includes recommendations for improvements to structures and operations of:

Levees Channels and Bypass Systems Reservoirs Fisheries and wildlife habitat Operations and Maintenance

Page 11: Marysville Levee Commissionfrrfmp.com/wp-content/uploads/2013/02/Feather-RFMP... · Floodway Levees Channels and Floodplains. Solution Strategies and ... L4 Bear River north levee

Levees: Raise crown elevation Increase levee cross section and improve its geometry Provide stability berms buttress the levees Provide waterside berms and erosion protection on the water side Provide cutoff walls, seepage berms, or relief wells Reconstruct deficient levees in place or construct levee setbacks Provide off‐stream transitory storage Provide improved access and visibility to facilitate inspection and 

flood fighting activities Remove or improve levee penetrations Provide overflow protection Provide vegetation management including root barriers

The agricultural and environmental heritage of the Feather River region should be preserved and enhanced through improved flood protection

Integration of Flood Protection, Agriculture & Environment

Page 14: Marysville Levee Commissionfrrfmp.com/wp-content/uploads/2013/02/Feather-RFMP... · Floodway Levees Channels and Floodplains. Solution Strategies and ... L4 Bear River north levee

Maintaining agricultural operations ensures:

• Economic vitality of the region preserved and enhanced• Limiting of dense residential development in flood‐prone areas

• Environmental benefits of farming• Access to resource stewardship and land management know‐how of farmers

Integration of Flood Protection, Agriculture & Environment

Benefits of Ecosystem Enhancement in Feather River Region: Increased floodplain 

inundation compatible with agriculture

Increased potential for channel migration

Increased extent of riparian vegetation

Improved fish passage at State Plan of Flood Control facilities (SPFC)

Integration of Flood Protection, Agriculture & Wildlife

Flood Protection Projects Benefit Agricultural & Environmental

• 200‐year flood protection for region

• Flood risk reduction for agricultural land

• Over 2,400 acres returned to the floodway for environmental restoration and/or agricultural leaseback opportunities
