DCA has launched geotechnical field work activities, advancing preconstruction explorations that will support engineering analyses and future design development for the Delta Conveyance Project. The work will collect detailed subsurface information on soil composition, groundwater conditions and geologic characteristics throughout the project corridor.

The program builds on 185 explorations and more than 33,000 feet of subsurface investigations completed since 2020.

Safety, environmental compliance and stakeholder coordination are central to the field program. DCA and DWR recently conducted joint field readiness and safety training covering environmental awareness, tribal cultural resources, public interaction protocols and health and safety requirements.

The field program also includes extensive environmental compliance and landowner coordination measures. Prior to drilling, teams complete site surveys and notifications, while digital tracking tools document communications, compliance requirements and field conditions in real time. DCA has also implemented a detailed Operation Readiness Review process to verify environmental, permitting and safety requirements before work begins at each site.

DCA has upgraded the Document Library on the project website, making it easier for the public, stakeholders and agency partners to access project materials and technical information. The refresh includes improved search and browsing tools, clearer organization and expanded filtering options to help users find reports and meeting materials more easily.

The upgraded library reflects DCA's ongoing commitment to transparency and public access as engineering, permitting and environmental review continue.
