Construction of Improvements to Mayhew Levee and Drain

The U.S. Army Corps of Engineers (Corps), in partnership with the Central Valley Flood Protection Board (formerly the Reclamation Board) (CVFPB) and the Sacramento Area Flood Control Agency (SAFCA) is constructing flood improvements to the Mayhew Levee and Drain.

The work comprises raising and widening the existing levee, and constructing a slurry wall beneath the levee.  A closure structure will be constructed near the mouth of the drain to prevent American River waters from backing up the drain, while still allowing internal drainage to drain to the American River.

A contract was awarded to FCI Constructors (FCI) in August 2007, and FCI began work in March 2008.    About every two weeks, we will update this webpage with a description of the activities expected to occur in the subsequent two weeks.

During the construction period, approximately March 1, 2008 to the end of December 2008, the Project area from the Mayhew Drain to the east end of the project (about 1,500 feet east of the Grist Mill Access) is closed to public access 24 hours a day/7 days a week.  Both the Grist Mill Access point and the Kansas Avenue Access point is closed.  Entering the fenced area of the project area is strictly prohibited until further notice.  The walking path immediately adjacent to the American River remains open, but this can only be accessed from points east or west of the Project area.  Please leash your dogs when walking along the outside of the orange fencing, near the construction area.  We appreciate your cooperation and your respect for these temporary restrictions.  Allowing the contractor to focus on completing the improvements benefits everyone.

UPCOMING CONSTRUCTION ACTIVITIES

December 24, 2008

The Mayhew Levee has been improved.  Work on the Mayhew Drain Closure Structure has been suspended until about May 15, 2009.

1. I understand that both the Grist Mill and Kansas Avenue access points are open and access control has been returned to County Parks.   There is some remaining cleanup to be accomplished at the Grist Mill Parking area at the American River and this area has been closed until after the holidays.
2. Work on the Mayhew Drain Closure Structure has been stopped for this year. The contractor has reinstalled a concrete lining to avoid any erosion problems this winter. At this time the drain, and the adjacent storm drainage pump station is fully functional and ready for winter rains.  Construction of the closure structure will be resumed next spring. The contractor has also completed construction of the slurry wall across the drain and will be restoring the drain to handle winter runoff.
3. Revegetation of the staging area will be delayed until 2010.  The staging area will be needed again next year for completion of the Mayhew Drain Closure Structure. The proposed revegetation plan is shown in the link identified below .
4. If you have a comment, suggestion, complaint, or compliment about the levee project, we’d like to hear it. Please use the comment section of our website.
