The Metropolitan Water District of Southern California (Metropolitan) proposes to install stairs and railings at the Diamond Valley Lake (DVL) West Dam structure to reduce the hazards associated with walking down the slope to access dam equipment. A small excavation will be required and concrete will be poured for the footing for the stairs; anchor holes will be drilled in the concrete to fasten the railing stairs, and ladder assembly to the dam structure. Equipment to be used includes a backhoe, dump truck, various handpowered tools, generators, and a crane. In addition, Metropolitan proposes to remove approximately 3,500 square feet of damaged canal liner in the San Diego Canal, replace soils with compacted materials, and replace the liner. Concrete and soils will be romoved to allow repair and replacement of the liner. Replacement of the liner will occur at five separate locations along the San Diego Canal (Stations 576+21, 576+27. 633+00, and 690+00); these locations are north and northeast of DVL. Equipment to be used includes an excavator, backhoe, dump trucks, jackhammer, and cement trucks. All work will be performed within Metropolitan's right-of-way fencing, which is located on both sides of the canal, and on the existing road.
