Preliminary evaluations of the levees surrounding West Sacramento indicate issues (PDF-244 KB) similar to those being identified in many Northern California communities. Results from these evaluations are being used to help prioritize and estimate the cost of necessary levee improvements.

Environmental Impact Statement/Environmental Impact Report 
The West Sacramento Area Flood Control Agency (WSAFCA) has filed a Notice of Preparation with the California Office of Planning and Research announcing the beginning of the Environmental Impact Statement/Environmental Impact Report (EIS/EIR) process for the proposed Southport Sacramento River Early Implementation Project (EIP).  The U.S. Army Corps of Engineers (USACE) published a Notice of Intent in the Federal Register on August 26, 2011, for the same purpose. The proposed EIP would implement flood risk–reduction measures along the Sacramento River South Levee, which protects the Southport community. 

A Notice of Intent for the preparation of the EIS/EIR has been posted in the Federal Register (Vol. 76, No. 16, pg 53423-4).

WSAFCA and USACE held a public scoping meeting to explain more about the proposed effort and collect public input about the scope and content of the EIS/EIR being developed for the EIP.  Two scoping meetings were held; both meetings had the same agenda, topics, and opportunity for comment: 

Date:   Thursday, September 15, 2011
Time:   First meeting from 3:30 to 5:30 p.m.
            Second meeting from 6:30 to 8:30 p.m.

Place: West Sacramento Recreation Center, Community Room
            2801 Jefferson Boulevard, West Sacramento

I Street Bridge Site (2008)

Construction of the first levee improvement project was completed at the end of November 2008, near the foot of the I Street Bridge.  The project consisted of a 475-foot long slurry wall that is approximately 37-feet in depth.  The slurry wall will protect from seepage, tree removals, and the reshaping of the levee.  The project also involved removing vegetation per the US Army Corps of Engineers standards, as well as a major telecommunications utility relocation.  The Riverwalk extension project commenced soon after construction was completed.

Sac Bypass/CHP Academy (2011)

Final EIS/EIR

Construction of the SacBypass-CHP Academy Project was completed in December 2011.  The levee segment selected for improvement is approximately 6,000 feet.  It extends from the Sacramento Weir 6,000 ft west along the south levee of the Sacramento Bypass.  The area south of the project site is occupied by the California Highway Patrol (CHP) Academy.  The project site consists of an earthen levee with a crown width of approximately 20 feet.  The levee segment along the Sacramento Bypass has a landside berm constructed as part of the USACE West Sacramento Project Levee Reconstruction Project Contract B, 1999.  Other Contract B levee improvements that fall within the extents of the CHP Academy EIP site include a waterside toe soil bentonite cutoff wall and an interior drain.  The elevation of the existing levee along the Sacramento Bypass ranges from approximately 38.1 feet to 40.3 feet (NAVD88).  In all cases, this elevation is more than 3 feet higher than the 200-year design water surface elevation for the Sacramento Bypass.  The 200 year design elevation for the TOL is below the previously authorized and accepted TOL for the West Sacramento Project.

The levee improvement plan includes levee reconstruction measures necessary to correct seepage and stability deficiencies.  The project includes slope flattening and installation of a cutoff wall to correct for stability and seepage deficiencies, respectively. Vegetation within the project extents will be modified, as needed, to comply with current Army Corps policy.
