Yerba Buena Engineering & Construction, Inc., under the U.S Fish & Wildlife
Service was contracted to perform repairs to the deteriorating Alviso Levee in the San Francisco Bay. Project Duration: 09/07-05/08.

Performed for the FWS, the project included the addition of rock protection to the faces of eight levees to reinforce the structures in response to severe erosion caused by bay waters. Some of the levee repairs also required dirt-fill to raise their height. In addition to levee repairs, Yerba Buena raised the grade on the trail at one levee, as well as the access road on another levee. Further, on the shoreline of levee A2W, a road base was installed to repair the driving surface, which provided shared access to Moffat Field and the FWS.

Approximately 5,000 yards of free dirt and recycled concrete were located for use on the project, which created a cost savings of more than $100,000 for the FWS. The source of dirt was within five miles of the contract site – minimizing delivery costs, while maximizing savings. The project was completed on time and within budget.
