Golden Door Properties, LLC v. County of San DiegoAnnotate this Case
San Diego County (County) challenged a judgment, writ of mandate, and injunction directing it to set aside its approvals of a Climate Action Plan (2018 CAP or CAP), Guidelines for Determining Significance of Climate Change, and supplemental environmental impact report (SEIR). The primary issue was whether a greenhouse gas (GHG) mitigation measure in the SEIR, called M-GHG-1, was California Environmental Quality Act (CEQA)-compliant. The superior court ordered the County to vacate its approvals of the CAP, Guidelines for Determining Significance, and the certification of the SEIR. The court also enjoined the County from relying on M-GHG-1 during review of greenhouse gas emissions impacts of development proposals on unincorporated County land. The Court of Appeal limited its holding to the facts of this case, particularly M-GHG-1. "Our decision is not intended to be, and should not be construed as blanket prohibition on using carbon offsets—even those originating outside of California—to mitigate GHG emissions under CEQA." The Court held: (1) M-GHG-1 violated CEQA because it contained unenforceable performance standards and improperly defers and delegates mitigation; (2) the CAP was not inconsistent with the County's General Plan; however (3) the County abused its discretion in approving the CAP because the CAP's projected additional greenhouse gas emissions from projects requiring a general plan amendment was not supported by substantial evidence; (4) the SEIR violated CEQA because its discussion of cumulative impacts ignores foreseeable impacts from probable future projects, (b) finding of consistency with the Regional Transportation Plan was not supported by substantial evidence, and (c) analysis of alternatives ignored a smart-growth alternative. The judgment requiring the County to set aside and vacate its approval of the CAP was affirmed because the CAP's greenhouse gas emission projections assumed effective implementation of M-GHG-1, and M-GHG-1 was itself unlawful under CEQA. Except to the extent that (1) the CAP is impacted by its reliance on M-GHG-1; and (2) the CAP's inventory of greenhouse gases was inconsistent with the SEIR, the Court found the CAP was CEQA-compliant.
