The Third District Court of Appeals recently weighed in on the interpretation of Public Resources Code section 21099(b)(2) (“Section 21099(b)(2)”) and newly enacted CEQA Guidelines section 15064.3, which govern the consideration of traffic impacts under CEQA. In Citizens for Positive Growth & Preservation v. City of Sacramento (2019) 43 Cal.App.5th 609 (“Citizens”), the Court determined that although Guidelines section 15064.3 does not become effective until July 1, 2020, Section 21099(b)(2) already prevents lead agencies from relying on impacts to vehicle delay to determine that traffic impacts are significant.
The Petitioner challenged the environmental impact report (EIR) prepared for an amendment to the City of Sacramento’s General Plan, alleging, among other things, that the project would increase congestion on city streets and would therefore have a significant impact on the environment. The Court disagreed, finding that level of service (LOS)—a method of determining traffic impacts based on congestion and wait times at intersections—is no longer valid under CEQA.


In a long-awaited decision, on December 24, 2018 the California Supreme Court in Sierra Club v. County of Fresno (S219783) affirmed, in part, and reversed, in part, the Fifth District Court of Appeal’s decision concerning a challenge to the adequacy of an EIR prepared for the Friant Ranch retirement community (“Project”). Employing a de novo standard of review, the Court found that the Project EIR is inadequate as a matter of law because the EIR did not make a reasonable effort to connect the Project’s air quality impacts to specific health consequences (or explain why it is not feasible to do so). The Court also upheld the lead agency County of Fresno’s discretion to substitute equally effective or more superior future mitigation measures and adopt mitigation measures that do not reduce the Project’s significant and unavoidable impacts to a less-than-significant level. This decision poses significant hurdles for project proponents going forward with new, heightened requirements for EIR analysis of environmental and health impacts and a more scrutinizing, independent legal standard of review for challenges to the adequacy of an EIR.
On October 2, after waiting over three-and-a-half years, the California Supreme Court finally heard oral arguments in Sierra Club et al. v. County of Fresno et al. (Case No. S219783). This case, which challenges an EIR prepared for the Friant Ranch retirement community in Fresno County, raises far-reaching and consequential CEQA questions, namely, the standard of review for the adequacy of an EIR’s discussion of required CEQA topics and the level of analysis needed to identify a project’s effect on human health.
In a March 2018 decision, the First Appellate District examined several CEQA issues pertinent to petroleum refining and hazardous materials transport. In Rodeo Citizens Association v. County of Contra Costa, the appeals court affirmed several findings of the lower court, dismissing challenges to the environmental impact report (“EIR”) prepared for a propane and butane recovery project at the Phillips 66 refinery in Rodeo. (The appeals court did not review the trial court’s order to the county to set aside the certification of the EIR and correct several other air quality related issues.) The appeals court found the risk of rail transportation of propane and butane was appropriately measured against the baseline of existing risks; the project description did not mask plans for the refinery to alter its crude oil feedstock; and that greenhouse gas impacts from downstream uses of petroleum products need not be evaluated.
