The shaft construction process would require a large crane or milling machine for the slurry panel excavation or panel excavator if cutter soil mix panels were […]

DCA may consider on-site acoustical surveys near potential construction sites to develop site-specific noise reduction methods. These types of surveys would not be conducted until specific […]

Specific decibel levels are not known for the screen cleaner mechanism. DCA anticipates further studies and analysis by acousticians.

There are many places in the world where tunnels with similar features referenced have been constructed or are under construction, including tunnels at the Port of […]

The potential tunnel alignments and shaft locations in the Central and Eastern Corridor are still being developed. At this time, it appears that two tunnel launch […]

Excavated soils, with or without peat, would need to be managed on-site to prevent particulate matter, including dust and peat material, from leaving the construction site […]

In July 2017, DWR approved a conveyance project in the Delta involving two tunnels referred to as “California WaterFix.” In his State of the State address […]

Reclamation districts (RDs) have important requirements for maintenance, monitoring and flood fighting. These efforts will need to continue during construction and operation of the Delta Conveyance […]

The dewatering water would be tested to determine if on-site treatment would be required prior to reuse or removal from the site. The treatment could range […]

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 […]
