Central Valley Flood Protection Plan

The Central Valley Flood Protection Plan (CVFPP) is California’s strategic blueprint to improve flood risk management in the Central Valley.  Prepared by the California Department of Water Resources (DWR) in accordance with the Central Valley Flood Protection Act of 2008 (Act) and adopted by the Central Valley Flood Protection Board (CVFPB) in June 2012, the CVFPP guides the State’s participation in managing flood risk in areas protected by the State Plan of Flood Control (SPFC). The CVFPP is updated every 5 years in accordance with the Act. The plan lays out strategies to:

  • Prioritize the State’s investment in flood management over a 30-year planning horizon
  • Promote multi-benefit projects
  • Integrate and improve ecosystem functions associated with flood-risk-reduction projects.

Although flood management has improved considerably in the Central Valley since the passage of State bonds in 2007 and the Act in 2008, this vast region still faces significant flood risk particularly with the urgent threat of climate change. Approximately 1.3 million Californians live and work in the valley’s floodplains, which contain approximately $223 billion worth of structures and their contentsAll of California and the nation could experience a devastating societal and financial impact from a major flood in the Central Valley. Without sufficient and sustained investment in Central Valley flood management, the risk to life and property will increase.

Each five-year cycle of the CVFPP includes an update of the following supporting documents: the State Plan of the Flood Control Descriptive Document Update, Flood System Status Report, Conservation Strategy, and the CEQA analysis.

CVFPP Implementation

Sacramento San Joaquin Drainage District Assessment District Feasibility Study  – Report of Findings

The 2017 CVFPP Update Investment Strategy identified three new potential funding mechanisms, including reutilizing authority existing in the California Water Code that has not been used since the 1930s that allows the Sacramento and San Joaquin Drainage District (SSJDD) to charge assessments to fund the local cost share of capital improvements and operation and maintenance (O&M) activities.

The Flood Board initiated the SSJDD Assessment District Feasibility Study (Study) in December 2019. The Study resulted in a Report of Findings (ROF). The purpose of the Study was refined to address the following objectives:

  • Evaluate the feasibility of an SSJDD Assessment District to provide local funding for system-wide improvements and O&M of associated flood control structures and levees within the State Plan of Flood Control;
  • Identify legislative changes required to implement an SSJDD Assessment District;
  • Perform beneficiary analyses to establish a reasonable formula to apportion the assessment across benefiting properties;
  • Provide recommendations for the formation and operation/administration of an SSJDD Assessment District; and
  • Prepare an implementation plan for establishing an SSJDD Assessment District.

On April 19, 2024, the Flood Board released the Public Draft ROF for a 2-week public review period. No public comments were received. The Final Report of Findings is linked below.

2022 CVFPP Update

The 2022 CVFPP Update evaluates progress made since passage of major State bonds in 2007 and recommends future management actions led by State, federal, and local partners to continue implementation of the CVFPP. The 2022 CVFPP Update focuses on three key themes:

  • Climate Resilience
  • Performance Tracking
  • Alignment with Other State Efforts

The 2022 CVFPP Update continues to build on the significant amount of work completed over the past 15 years to better understand and develop priorities to improve flood risk management in the Central Valley. Using new information, updated science, and innovative tools, irecommends priority actions to address flood risk in the face of climate change. Development of the 2022 CVFPP Update was informed by a robust, multi-year communications and engagement process that involved frequent discussions with State, federal, Tribal, and local partners.

2017 Central Valley Flood Protection Plan Update

The Central Valley Flood Protection Board, after public hearings and review, adopted the 2017 CVFPP Update on August 25, 2017. The CVFPP provides a comprehensive framework for system-wide management and flood risk reduction planning for the Sacramento and San Joaquin River Basins. This first update to the CVFPP refines the overall near-term and long-term investment needs established in the CVFPP, and includes recommendations on policies and financing that aim to support comprehensive flood risk management actions locally, regionally, and system-wide.
