The Sacramento River East Levee (SREL), part of the American River Common Features (ARCF) 2016 Project, was executed by USACE under four different contracts. The project assumes significance due to its location and importance for public safety and asset protection. The first two contracts were supported by GEI and HDR who provided engineering during construction services related to civil and geotechnical engineering. The third and fourth contracts were supported by Kleinfelder and Stantec, which are the topic of this presentation. Contract 3 involved construction of 2 miles of seepage cutoff walls in the Pocket area in 2022 and Contract 4 involved construction of seepage cutoff walls at 4 separate locations in 2023 and 2024 from the Broadway Avenue area to the Freeport area. Contracts 3 and 4 flood protection features are intended to reduce the flooding risk to critical infrastructure in Sacramento, California. The project was constructed through a USACE Sacramento District contract. This presentation will summarize the contract design and construction stages. Various types of cutoff walls will be reviewed and design and construction challenges will be discussed. (more)
