The petition alleges bias and legal error favoring controversial Delta tunnel project
Sacramento County, San Joaquin County, the City of Stockton, Central Delta Water Agency, Sacramento County Water Agency, and Sacramento Area Sewer District (Petitioners) have sued the Delta Stewardship Council (Council) in Sacramento County Superior Court. The new suit seeks to invalidate a January 2025 Council decision regarding the controversial Delta Tunnel that also has broad consequences for other actions under the 2009 Delta Reform Act (Act). The Delta and its communities, the public interest requiring agency compliance with the Act, and the integrity and reputation of the Council all would suffer if the decision is allowed to stand.
The case arises out of a 2024 lawsuit challenging the California Department of Water Resources’ (DWR) Delta Conveyance Project (DCP or Delta Tunnel). In May 2024, the trial court stopped DWR from proceeding with geotechnical activities that DWR admitted were a key component of the Delta Tunnel project. DWR has admitted the Delta Tunnel is a “covered action” under the Act. Under the Act, a project proponent may not implement a covered action before certifying the whole project is consistent with the Delta Plan adopted by the Council. DWR had not done so.
After the trial court issued a preliminary injunction preventing DWR from undertaking the geotechnical activities, DWR attempted to sidestep the court’s ruling by submitting a smaller part of DCP geotechnical activities to the Council. In doing so, DWR asserted that the activities were not a covered action. The Petitioners, along with other Delta public agencies, tribes and environmental organizations, challenged DWR’s attempt to carve off a part of the DCP and bypass the Act’s requirements. In January 2025, the Council agreed there was no covered action, and thus it lacked jurisdiction in the matter. The Council nevertheless issued a 32-page decision that blessed DWR’s desire to chop the DCP into smaller pieces to avoid regulatory oversight.
In the new lawsuit, Petitioners accuse the Council of abusing its discretion and engaging in a biased and results-oriented process in favor of the controversial Delta Tunnel. The Council’s bias was confirmed by the fact that a Council staff member who participated in the certification appeal had previously filed a declaration supporting DWR’s opposition to the preliminary injunction in the trial court, and by the Council’s decision to issue a lengthy decision interpreting the Act in DWR’s favor despite having no jurisdiction to do so. Moreover, neither DWR nor the Council disclosed their communications concerning the Delta Tunnel and the geotechnical activities in private “early consultation” meetings preceding the Council’s decision. The Council staff’s presentations at the hearings also were skewed in favor of DWR’s position.
In addition to invalidating the Council’s decision on the DCP geotechnical activities, the lawsuit seeks a court decision confirming the Act prohibits “piecemealing” of covered actions for certification.

PRIOR COVERAGE ON MAVEN’S NOTEBOOK

DWR: The Delta Stewardship Council affirms that DWR’s planned geotechnical investigations are not within their jurisdiction and are not a Covered Action
From the Department of Water Resources: Today the Delta Stewardship Council (DSC) affirmed that the Department of Water Resources’ (DWR) planned geotechnical investigations are not a “Covered Action” under the Delta Reform Act. Therefore, the DSC dismissed all appeals on the grounds that it does not have jurisdiction over these planned geotechnical activities. In order to come to that conclusion, the DSC considered whether project proponents can consider portions of a project in the Delta Plan consistency process. In consideration of the scope of the 2024-2026 Proposed Geotechnical Activities, the DSC found that DWR was […]

COMMENTARY: Delaying the Delta Conveyance Project puts California’s water security at risk
By Jennifer Pierre, General Manager of the State Water Contractors The State Water Project, a cornerstone of California’s water delivery system, runs on 1960s-era infrastructure. This aging system is increasingly vulnerable to climate change, seismic risks and environmental challenges. Modernizing it with the Delta Conveyance Project (DCP) is essential to ensure sustainable and reliable access to the water that powers our state’s communities, farms and industries. That’s why recent attempts to delay progress on the DCP before the Delta Stewardship […]
