Document Description
The California Aqueduct in this reach known as the Lower Quail Canal has had a history of problems with canal foundation instability and seepage. Other reaches of this embankment both upstream and downstream of this site were previously repaired by the installation of designed drainage facilities (seepage blankets). The target section of the embankment to be repaired by this project is approximately 500 feet in length between aqueduct stations 310 to 316. The embankment slope will be cleared of existing weedy vegetation and regraded, and then a gravel berm with drainage pipes will be installed and covered with soil. Native soil previously excavated during canal consttruction will be excavated on-site for topsoil fill material. All areas of disturbed soil will be reseeded with an appropriate mixture of native plants for erosion control. The total project area will not exceed 3 acres of disturbed soil surface, including both the embankment repair area and the adjacent borrow area. This project will have no adverse environmental impacts, and the beneficiaries will be the State of California and all State Water Project users. Stabilization of the seepage site is considered critical to avoiding a potential future catastrophic failure of the aqueudct liner in this section such as occurred in 1984.
