Huff's Corner FSRP Project
The section of Cache Creek known as "Huff's Corner" is a small reach on the right bank extending approximately 2,700 feet upstream from Interstate 5. The levee was initially constructed by the U.S. Army Corps of Engineers in 1960, and Yolo County has been the local maintaining agency since its construction. Only the eastern 1,500 feet of this levee is within the State Plan of Flood Control.  

In October 2012, Yolo County, through the Central Valley Flood Protection Board, initiated the process of forming a Maintenance Area for the maintenance of the levee. However, the Maintenance Area was not formed because the initial cost of completing the deferred maintenance required for the formation of a Maintenance Area was prohibitive to the County and local landowners. 

In early 2018, the County sought engineering recommendations to determine what would be required to complete the deferred maintenance to restart the Maintenance Area formation process. In addition to the deferred maintenance, two major project improvements were identified: (1) a raise of the entire reach of the levee to restore it to its original design height, and (2) implementation of a "reconfiguration" project within the Lower Cache Creek channel to control erosional forces against the levee and remove excess sedimentation. These two improvements were combined to create the Huff's Corner Levee Raise & Channel Reconfiguration Project.

In August 2019, the County and the California Department of Water Resources ("DWR") entered into a Project Agreement to complete the design, environmental permitting, and construction of the improvement projects. Utilizing funds provided by the DWR agreement, as well as local funding contributions from the Cache Creek Resources Management Plan, the County was able to develop 100% designs for both project components, secure all necessary permits and environmental clearances, and complete the in-channel reconfiguration project component. Due to unforeseen costs associated with construction, environmental mitigation, and securing land acquisition/right-of-way, the Project Agreement did not contain sufficient budget for the construction of the levee raise project component. In April 2024, the County and DWR entered into a Project Partnership Agreement to fund "Phase II" of the project, which will finish the project by constructing the levee raise project component, in addition to repairing the channel reconfiguration project and implementation of an off-site mitigation project.  FlowWest served as the lead design engineer for the channel reconfiguration portion of the project. Construction of this project element was completed in December 2022, but early 2023 rains resulted in creek flows that damaged the newly constructed terrace that was built within the creek channel.
