Document Description
The Project consists of decommissioning the Pine Mountain Tunnel and the existing Ross Reservoir and the construction of three new water tanks providing 7.8 million gallons of potable water storage. The Project would provide operational flexibility by replacing lost storage from the decommissioned Pine Mountain Tunnel and Ross Reservoir and additional storage to meet current storage standards and the emergency needs of the existing system. The Project area includes two tank sites, an excavation soil disposal site, and the Pine Mountain Tunnel site, all on District property. A list of the Project sites is provided in Table 1, Project Sites and Locations. Figure 2, Project Locations, illustrates the location of each site.
