Central Valley Flood Protection Plan

Primary 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

 Sustainable, integrated

flood management

slide-4
SLIDE 4

Purpose of the RFMP

Build 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

  • pportunities.

Flood Hazards in the Region

 Reservoirs: Flood Risk Reduction and Potential

Hazards

 Oroville  New Bullards Bar  Camp Far West

 Levees

 SPFC Facilities  Floodway Levees

 Channels and Floodplains

Solution Strategies and Management Actions

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

  • perations of:

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

slide-11
SLIDE 11

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

Solution Strategies and Management Actions

slide-12
SLIDE 12

CVFPP physical and operational elements applicable to Feather River region:

 Forecast Coordinated Operations and Forecast Based

Operations (FCO and FBO)

 New Bypass Construction and Existing Bypass

Expansion

 Flood Structure Improvements  Urban Improvements  Small Communities Improvements  Rural Agricultural Area Improvements  Ecosystem Restoration

Solution Strategies and Management Actions

slide-13
SLIDE 13

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

slide-14
SLIDE 14

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

slide-15
SLIDE 15

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

slide-16
SLIDE 16

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

TRLIA’s Bear and Feather River levee setbacks provide:
