Southport EIP Levee Improvements

The Southport EIP project consists of improvements to about 7 miles of levee on the Sacramento River in West Sacramento to mitigate slope instability and underseepage deficiencies. Mitigation measures consist of a combination of new setback levee, slope flattening, seepage cutoff walls and seepage berms. BCI is the geotechnical design engineer for the project and has been involved since preliminary design began in 2010.   BCI has completed over 100 subsurface explorations, extensive laboratory testing and engineering analysis, and prepared numerous reports and technical memoranda for the project including:   


  • Geotechnical Basis of Design Report
  • Geotechnical Data Report
  • Borrow Site Evaluation Reports

Technical Memoranda

  • Rapid Drawdown Evaluation
  • Site Seismicity
  • Geotechnical Value Engineering
  • Sensitivity Analysis for On-Site Borrow Excavations  

BCI completed geotechnical evaluations for preliminary, 15% design, 65% design and 90% design within schedule and under budget.  The West Sacramento Area Flood Control Agency has also retained BCI to provide Quality Assurance materials testing during construction of the Southport EIP levee improvements.


"Credit for the project earthwork savings on the SIP improvements, and the flexibility we have with the setback levee fill specifications goes to your [BCI’s] diligence and follow-through in these areas.
