July 23rd: Sacramento River East Levee Project Presentation

When:  Jul 23, 2024 from 11:40 AM to 01:00 PM (PT)

With many construction projects in full swing for the middle of summer, join us for a break from the work rush (and the heat!) to learn about a great local project here in Sacramento. We will be meeting at The Old Spaghetti Factory on J Street and lunch will be served. Please select your preferred meal when you register. More registration information/cost are provided below!

We have lined up Christopher Hamilton from U.S. Army Corps of Engineers and Tim Williams, PE, GE and Kimberly Brown at Kleinfelder to present on the "Sacramento River East Levee Improvements: Design and Construction" for this month. Register now for our In-Person July 23rd presentation! 

About the Presentation

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.


About the Speakers

 

Mr. Hamilton is a geotechnical engineer for the U.S. Army Corps of Engineers, Sacramento District (USACE). He has been with USACE since 2018, working primarily on Civil Works projects. Since 2020, he has been the lead field engineer for the Sacramento River East Levee (SREL) Seepage and Stability contracts under the American River Common Features 2016 project. He has provided quality assurance and engineering analysis on a variety of cutoff walls, including conventional open trench (soil-bentonite (SB) and slag cement-portland cement-bentonite (SCCB)), deep mix method (DMM), and jet grouting (single and triple fluid). He is the geotechnical lead for the SREL Contract 4 project (2023-2024), which includes jet grouting, DMM, buried curb wall, seepage and stability berm, and earthwork.

 Mr. Williams has over 37 years of experience in geotechnical engineering and is a senior principal geotechnical engineer in Kleinfelder's Sacramento office. In that capacity, he is responsible for large multidisciplinary levee evaluation projects. Mr. Williams is responsible for developing work scopes for small to large levee evaluations as well as preparing and implementing large field exploration programs based on research of existing reports and information, geologic and geomorphic interpretation, and input from geophysics. He oversees laboratory testing programs and the preparation and presentation of field information. His work includes preparation of geotechnical reports that meet regulatory requirements (including Problem Identification Reports, Alternative Analysis Reports, and Basis of Design Reports).  This includes preparing recommendation and plans for open trench slurry cutoff (soil bentonite and cement bentonite), deep mix method, and jet grout cutoff walls. He was lead geotechnical engineer for SREL Contracts 3 and 4 for design and engineering during construction support. 

Ms. Brown has 17 years of experience in the fields of geotechnical engineering and construction with an emphasis on flood control, water, and wastewater facilities. She planned and executed the geotechnical subsurface investigation for the SREL-3 and SREL-4 projects which included performing hollow stem auger, mud rotary, sonic borings, and CPTs. She prepared the SREL-3/4 Geotechnical Data Report and lead the SREL-3/4 Geostudio analysis including preparation of two Supplemental Geotechnical Analysis Memos. She has served as the field lead during construction of the SREL-3 and SREL-4 construction, which has included open trench soil bentonite, open trench Slag cement-cement-bentonite, Deep Mix Method, and jet grout cutoff walls, construction of two Slumps, levee re-building, earthwork and concrete curb wall placement and flood wall raise for freeboard adjustments, and stability and seepage/stability berm construction. Lastly, Ms. Brown has supported USACE in reviewing and responding to Submittals and RFIs during construction of the SREL-3 and SREL-4 projects.
