FIRST APPELLATE DISTRICT

DIVISION ONE

PRESERVE ROSS VALLEY, Plaintiff and Appellant,

A174392

v. COUNTY OF MARIN, (Marin County Super. Ct. No. CV0005168)

Defendant and Respondent,

MARIN CATHOLIC HIGH SCHOOL et al., Real Parties in Interest and Respondents.

Plaintiff Preserve Ross Valley filed a petition for writ of mandate pursuant to the California Environmental Quality Act (Pub. Resources Code,1 § 21000 et seq.; CEQA) challenging the County of Marin’s (County) approval of a project to install and use field lights at Marin Catholic High School’s (Marin Catholic) athletic stadium. After the statute of limitations period closed, plaintiff filed an amended petition which substituted in the Archdiocese of San Francisco Parish and School Juridic Persons Real

Property Support Corporation (RPSC) as a real party in interest. The trial court dismissed plaintiff’s CEQA claim for failure to join RPSC within the statute of limitations period, concluding, as relevant here, that the substitution did not relate back to the filing of the original petition. Plaintiff challenges the dismissal, arguing the relation back doctrine applies and, therefore, the naming of RPSC was timely. We agree. Accordingly, we reverse and remand for the trial court to rule on the merits of plaintiff’s CEQA cause of action.

I. BACKGROUND

A. The Project In May 2024, Marin Catholic applied to install field lights at its athletic stadium and associated bleacher and pedestrian pathway lighting. The project includes four, 80-foot tall light poles installed on each side of the field using LED technology. Field lighting would allow Marin Catholic sports teams to practice later into the evening and to play evening games.

After reviewing the application, county staff determined the project was exempt from CEQA under three categorical exemptions.2 In October 2024, the Planning Commission held a hearing to consider the application. The Planning Commission determined the project was not exempt from CEQA and directed staff to conduct an initial study. After Marin Catholic appealed, county staff recommended the Board of Supervisors deny the

2 Categorical exemptions apply to “projects which have been

determined not to have a significant effect on the environment and which shall, therefore, be exempt from” CEQA. (Guidelines, § 15300.) All references to “Guideline” or “Guidelines” are to the Guidelines codified in the California Code of Regulations, title 14, section 15000 et seq. They are guidelines for the implementation of CEQA, developed by the Governor’s Office of Planning and Research and adopted by the Secretary of the Resources Agency. (§ 21083.)

appeal, uphold the Planning Commission’s determination, and require preparation of an initial study. As an alternative, staff indicated that because Marin Catholic had submitted a revised good neighbor plan providing greater specificity regarding lighting usage and noise impacts, the Board of Supervisors may decide to approve the CEQA exemption.

In December 2024, the Board of Supervisors overturned the Planning Commission’s decision, found the project exempt from CEQA pursuant to the Class 11 (Guidelines, § 15311) and Class 14 (Guidelines, § 15314) categorical exemptions, and approved the project. It conditioned approval on, among other things, Marin Catholic’s implementation and compliance of its good neighbor plan. On December 20, 2024, the County, by its Community Development Agency, filed a notice of exemption (NOE). The NOE identified Marin Catholic as the entity proposing to install new field lighting at its athletic stadium. As “project sponsor,” the NOE identified one entity: “Archdiocese of San Francisco.” (Boldface and some capitalization omitted.) RPSC, by its full name, was not identified in the NOE. B. Procedural History On January 23, 2025, plaintiff filed a petition for writ of mandate alleging a cause of action pursuant to CEQA.3 Plaintiff alleged the County violated CEQA by exempting the project from environmental review, asserting the project did not fall within the Class 11 and Class 14 exemptions. Plaintiff alleged the project will likely have significant environmental impacts due to light and noise. Plaintiff named Marin Catholic and the “Roman Catholic Archbishop of San Francisco (aka

‘Archdiocese of San Francisco’)” as real parties in interest, stating that the NOE listed the “Roman Catholic Archbishop of San Francisco (aka ‘Archdiocese of San Francisco’)” as the project sponsor. Plaintiff also named Roe real parties in interest.

Plaintiff then filed an ex parte application for a temporary restraining order and request for a preliminary injunction to enjoin construction of the light poles. In opposing the application, Marin Catholic argued, as relevant here, that plaintiff could not prevail on the merits of its CEQA claim because it failed to join RPSC—a necessary and indispensable party—within the statute of limitations period. Marin Catholic explained the following: The owner of the property is “The Archdiocese of San Francisco Parish and School Juridic Persons Real Property Support Corporation,” i.e., RPSC, a separate corporate entity from the party that was named in the petition. (Italics omitted.) In 2008, the Roman Catholic Archbishop of San Francisco granted the property to RPSC, who remains the sole property owner. Due to space limitations in the electronic application form, the name of the property owner was shortened to “ ‘Archdiocese of San Francisco’ ” in some project materials.

Based on this information, on February 18, 2025, plaintiff filed a first amended petition where it named Marin Catholic and RPSC as real parties in interest. The amended petition alleged that plaintiff substituted in RPSC as a Roe party pursuant to Code of Civil Procedure section 474. The parties then briefed Marin Catholic’s demurrer to the amended petition and plaintiff’s request for a preliminary injunction. The trial court subsequently overruled the demurrer and granted a preliminary injunction. As to the preliminary injunction, the trial court concluded that plaintiff had some probability of prevailing on the substantive merits of its CEQA claim and that the balance of harms weighed in favor of issuing a preliminary

injunction. The parties then briefed the merits of the claims alleged in the amended petition.

In June 2025, the trial court filed an order ruling on plaintiff’s amended petition. The court dismissed the CEQA cause of action for failure to join RPSC—who it determined was a necessary and indispensable party— within the 35-day statute of limitations period. The court determined that plaintiff “had imputed knowledge of the correct party’s identity” at the time it filed its original petition so, therefore, the Roe amendment did not relate back to the filing of the original petition. The court subsequently entered judgment against plaintiff.
