ACTION ALERT: The Newsom Delta Tunnel Process Begins

The long process of official DWR-sponsored meetings around the Environmental Impact Report for the Delta tunnel begins this summer. We recommend that all our followers register for the webinars sponsored by DWR and the Design Construction Authority to listen and respond with smart, factual, yet passionate critique as necessary. Head and heart make for the best responses.
We will be reading documents and providing analysis in great detail on the first topics rolling out the door because we are already picking up on flaws in messaging.  However, the details are always what matter — and we will be combing through the details as we have always done to share with all of you. Our work on the Delta tunnel isn’t over.  Let’s rally ourselves to represent the truth.

Yours in service,
The Restore the Delta Team

Schedule and Topics Announced 
The Department of Water Resources (DWR) is hosting four informational webinars between July and September 2021 to provide background information related to preparation of the Draft Environmental Impact Report (EIR).  

While not a requirement of the California Environmental Quality Act, DWR is planning the webinars to keep the public and interested stakeholders informed about the current progress related to preparation of the Draft EIR. Each webinar will feature presentations from technical staff about the approaches, methodologies and assumptions to be utilized in conducting impact analyses in the Draft EIR. Information about impact findings and specific mitigation measures is not expected to be available but will be included in future outreach efforts following publication of the Draft EIR.

All information and materials related to the webinars can be found here.

About the Delta Conveyance Project 
The proposed Delta Conveyance Project would modernize the water transport infrastructure in the Sacramento-San Joaquin Delta (Delta) by adding new facilities to divert water and upgrading the current conveyance system to also include a tunnel for conveyance. If approved, these updates would ensure climate resiliency and the reliability of the state’s largest source of safe, affordable and clean water for 27 million Californians, 750,000 acres of farmland and continued support for local water supply projects such as regional stormwater capture, water conservation, recycled water and groundwater management. The Delta is the center of California’s vital water distribution system and a critical link in how water is moved to all parts of the state, however, the infrastructure that moves this water through the Delta is outdated and at risk of failure due to sea level rise or seismic activity. The infrastructure updates proposed as part of the project would give DWR the flexibility to divert, move and store water, consistent with all regulatory requirements, when it becomes available for use when supplies may otherwise be limited.
The project is currently in the initial planning and permitting phase, including compliance with state and federal environmental review processes and all other required regulatory approvals. Additional project-related information and resources can be found here.
