Launch shaft sites are the largest land footprints of the Delta Conveyance Project given the acreage it takes to place tunnel boring machines into the ground, support tunneling operations, and store the reusable tunnel material (RTM) excavated from the tunnel. The Delta Conveyance Design and Construction Authority (DCA), working at the direction of the Department of Water Resources (DWR), has identified a way to construct 45 miles of tunnel with only two launch sites, each including two launch shafts, that are strategically located to minimize impacts.
