Central Valley Flood Protection Board

The Central Valley Flood Protection Board (CVFPB) is the State regulatory agency responsible for ensuring that appropriate standards are met for the construction, maintenance, and protection of the flood control system that protects life, property, and wildlife habitat in California’s vast and diverse Central Valley from the devastating effects of flooding. CVFPB issues encroachment permits and works with other agencies to improve the flood protection structures, enforces removal of problematic encroachments, and keeps watch over the Central Valley’s continually improving flood management system.



In accordance with the Governor’s order, the Board will continue to host hybrid meetings and workshops through 2023.  Locations and access information for future meetings will be posted on our homepage and updated as needed.

For public drop off of physical documents, including applications and fees, we can be contacted by phone or email as noted below to schedule a drop off.

  • With our new hybrid teleworking environment, most staff are only at our office location on Tuesdays each week. Administrative staff are available at the front desk Tuesdays and Thursdays from 8:30 am – 3:00 pm. Appointments are required to meet with staff or receive in-person assistance at the front desk.  If you are currently working with a staff member on an item, please continue to contact that staff member.  If you need general information, please contact the general mailbox at Questions@CVFlood.ca.gov.

  • We will be prioritizing permits based upon health and safety factors, including the availability of staff and partners, and application processing times may be extended during this period.  Please bear with us as we work through this new system.

  • Past recordings of Board meetings and workshops can be found on the CVFPB YouTube Channel

California Reservoir Dam Release Update as Water Levels Rise

From Newsweek – California water officials are releasing water from Oroville Dam as the lake’s water levels continue to rise with more rain on the way. “Water releases from Lake Oroville were increased in advance of a series of storms and provide flood protection to downstream communities by maintaining storage capacity in the reservoir for additional rain capture,” a DWR spokesperson told Newsweek. California’s Department of Water Resources (DWR) opened the main spillway at Oroville Dam to provide flood protection for downstream communities in advance of more rain forecast for California. Lake Oroville’s water levels had jumped significantly over the past few months as several atmospheric rivers battered the state with torrential rain and heavy snow. (more)

Mapping Earth’s Atmospheric Rivers Could Help Improve Predictions for Intense Rain

From The Independent tv – Scientists have developed the world’s first real-time map showing the flow of atmospheric rivers in the sky, which transport intense moisture and drive extreme rainfall, an advance that may lead to better flood predictions. When these atmospheric rivers laden with moisture hit the skies over land they may lead to extreme weather events such as cyclones or typhoons and flooding. But previous models to view these rivers overestimated the frequency of rain they produced while underestimating the rain’s intensity. Now the new model can automatically detect these sky rivers using satellite observations, and provide a much more accurate picture of impending extreme weather events around the world, scientists say.

Central Valley Flood Protection Board (CVFPB) and Department of Water Resources (DWR) Receive Floodplain Management Association’s (FMA) Integrated Flood Management Award

This award is given to individuals or project teams who have prepared and/or implemented a locally-approved, state-approved, or federally-approved multi-objective flood management plan. Candidate projects should demonstrate innovative advancements in water management as well as collaborative partnerships with community groups and the general public. Project outcomes should benefit many stakeholder interests such as environmental, flood control, recreational, and emergency planning and responsiveness.

“The Central Valley Flood Protection Board and DWR are proud to receive the Floodplain Management Association’s Integrated Flood Management Award for the 2022 Central Valley Flood Protection Plan (CVFPP) Update.” The CVFPP Update was recognized for a robust, multi-year communication and engagement process involving state, federal, Tribal, regional, and local partners. DWR, with CVFPB input, incorporated the newest information, updated science, and innovative tools to develop priorities for improving flood risk management in the Central Valley. CVFPB officially approved the Update on December 16, 2022. Learn more about the CVFPP here. Congratulations to both agencies!
