With these new proposed intake locations, the State Water Project would have greater flexibility to adapt to climate change, manage rising sea levels, function in the […]

During the ITR team review, it was discussed that use of maintenance shafts approximately every 5 miles with full maintenance procedures at those shafts would substantially […]

Over the lifetime of the Delta Conveyance program, the facilities would be designed for the 200-year flood event, projected sea level rise for year 2100, freeboard […]

Decisions about the post-construction design have not been completed. There are many considerations currently being discussed, including not removing the shafts to allow for access into […]

As currently proposed, the shaft would be constructed with a diaphragm wall or concrete shell that would extend to the bottom of the tunnel where there […]

The Delta Conveyance program facilities, including tunnel shafts that are currently proposed to remain following construction, would be constructed at elevations greater than the 200-year flood […]

As currently proposed, a dedicated high-voltage power supply would be connected to the launch shaft sites to power the tunnel boring machine cutter head.

As currently proposed, the maintenance shaft sites would only be sized to remove the cutter head. The launch shaft sites would be sized to lift the […]

The ITR report’s note reflects the fact that the current tunnel corridors do not contain active faults and tunneling options themselves would not be uniquely affected […]
