SB 63 California Senate · 2025-2026 Regular Session

San Francisco Bay area: local revenue measure: public transit funding.

Summary
(1) Existing law creates the Metropolitan Transportation Commission as a local area planning agency for the 9-county San Francisco Bay area with comprehensive regional transportation planning and other related responsibilities. Existing law creates various transit districts located in the San Francisco Bay area, with specified powers and duties relating to providing public transit services. This bill would establish the Public Transit Revenue Measure District with jurisdiction extending throughout the boundaries of the Counties of Alameda, Contra Costa, San Mateo, and Santa Clara and the City and County of San Francisco and would require the district to be governed by the same board that governs the commission, thereby imposing a state-mandated local program. The bill would authorize a retail transactions and use tax applicable to the entire district to be imposed by the board of the district or by a qualified voter initiative for a duration of 14 years, and in an amount of 0.5% in each of the above-described counties located within the district and 1% in the City and County of San Francisco, subject to voter approval at the November 3, 2026, statewide general election. After payments are made for various administrative expenses, the bill would require the district to transfer specified portions of the proceeds of the tax to the commission for allocation to certain programs and other purposes and for allocation to the Alameda-Contra Costa Transit District, the Peninsula Corridor Joint Powers Board, commonly known as Caltrain, the San Francisco Bay Area Rapid Transit District, the San Francisco Municipal Transportation Agency, and other specified transit agencies, for transit operations expenses, and would require the district to transfer specified portions of the proceeds of the tax directly to other specified local transportation agencies, including the San Mateo County Transit District and the Santa Clara Valley Transportation Authority, for public transit expenses, as prescribed. By adding to the duties of local officials with respect to elections procedures for this bill on behalf of the district, the bill would impose a state-mandated local program. (2) Existing law requires the commission to develop regional transit service objectives, develop performance measures of efficiency and effectiveness, specify uniform data requirements to assess public transit service benefits and costs, and formulate procedures for establishing regional transportation priorities in the allocation of funds for transportation purposes. This bill would require the commission to contract with, and manage, a third-party consultant to conduct a financial efficiency review of the Alameda-Contra Costa Transit District, Caltrain, the San Francisco Bay Area Rapid Transit District, and the San Francisco Municipal Transportation Agency, as specified. The bill would require the review to be completed in 2 phases, with the analysis for the 2nd phase only required if the tax measure is approved by the voters of the Public Transit Revenue Measure District. The bill would require the consultant to transmit the analysis for each phase to an oversight committee, which the bill would create with a prescribed membership, for review and adoption. The bill would require a transit operator subject to the financial efficiency review to take specified actions in response to the analysis for the first phase and, subject to review of the oversight committee, to adopt an implementation plan that describes the cost-saving measures identified in the analysis for the 2nd phase that the operator plans to implement, as specified. The bill would require a transit operator subject to the financial efficiency review to verify its compliance with the requirements of the review as a condition of receiving funds from the tax measure approved by the voters of the district. The bill would require each transit operator to which the commission allocates funds to comply with a maintenance of effort requirement as a condition of receiving those funds, as provided. This bill would require the commission, if the tax measure is approved by the voters of the district and other conditions are satisfied, to establish an ad hoc adjudication committee for a transit operator subject to the above-described financial efficiency review to assess and adjudicate petitions submitted by a participating county transportation entity, as defined, or a county board of supervisors with regard to the performance of the transit operator within the geographic jurisdiction of the entity submitting the petition, as provided. As part of this process, the bill would require an ad hoc adjudication committee, among other things, to determine whether to direct the commission to withhold funding from the tax measure allocated to the transit operator if the committee agrees with a claim regarding the performance of the transit operator, as specified. This bill would require the commission to submit a report to the Legislature on or before March 31, 2026, on its forecast of the impacts to ridership on the Alameda-Contra Costa Transit District, Caltrain, the San Francisco Bay Area Rapid Transit District, and the San Francisco Municipal Transportation Agency from planned transportation projects and strategies included in its adopted regional transportation plan. By adding to the duties of the commission, the bill would impose a state-mandated local program. (3) The Bay Area County Traffic and Transportation Funding Act authorizes the formation of county transportation authorities in each of the 9 bay area counties, and provides for the imposition of a retail transaction and use tax in each of those counties of either 12 of 1% or 1%, subject to voter approval, with revenues to be used for various transportation purposes. This bill would instead provide that a retail transaction and use tax imposed under those provisions in the County of San Mateo or the City and County of San Francisco may be imposed in 18 of 1% increments up to 1%. (4) This bill would declare that its provisions are severable. (5) The California Constitution requires the state to reimburse local agencies and school districts for certain costs mandated by the state. Statutory provisions establish procedures for making that reimbursement. This bill would provide that, if the Commission on State Mandates determines that the bill contains costs mandated by the state, reimbursement for those costs shall be made pursuant to the statutory provisions noted above.

MAJOR
SB 63 (Connect Bay Area Act) was substantially amended to narrow its focus from general transportation funding to public transit funding specifically, fix the tax duration at 14 years (previously a flexible 10-15 year range), set San Francisco's tax rate at exactly 1 percent (previously a range of 0.5 to 1 percent in 1/8 percent increments), and add specific revenue allocation percentages for each county. The amendment also introduces new oversight mechanisms including an ad hoc adjudication committee that can direct the commission to withhold funding from underperforming transit operators, a two-phase financial efficiency review with an oversight committee, and judicial validation procedures for the tax ordinance.
SCOPE

The district was renamed from 'Transportation Revenue Measure District' to 'Transportation Public Transit Revenue Measure District,' narrowing the bill's purpose from general transportation funding to public transit funding specifically.

The opt-in mechanism for San Mateo and Santa Clara counties (previously Section 67711, with a deadline of August 11, 2025) was removed. All four counties plus San Francisco are now directly included in the district's jurisdiction, with a new Section 67712 clarifying that the title applies only to those identified jurisdictions.

TIMELINE

The tax duration was fixed at 14 years, replacing the previous flexible range of 10 to 15 years. This removes legislative discretion over the tax period.

FISCAL

San Francisco's tax rate was fixed at exactly 1 percent, replacing the previous range of no less than 0.5 percent and no more than 1 percent in 1/8 percent increments. Other counties remain at 0.5 percent.

Specific revenue allocation percentages were added: 0.25 percent of revenues from Alameda, Contra Costa, San Mateo, and Santa Clara counties each, and 0.13 percent from San Francisco, are transferred to the commission for administrative costs before other allocations.

Election cost reimbursement was narrowed: the previous provision allowing reimbursement from 'any eligible funds provided by the commission or other public or private entity' if the measure fails was removed. Reimbursement is now only from proceeds of the measure itself.

ENFORCEMENT

A new ad hoc adjudication committee was created that can assess petitions from county transportation entities or boards of supervisors regarding transit operator performance and direct the commission to withhold funding from a transit operator if it agrees with a performance claim.

A new Section 67736 was added establishing judicial validation procedures, allowing the district or any interested person to bring an action within 30 days after voter approval to determine the validity of the tax ordinance in superior court.

REQUIREMENT

The financial efficiency review was restructured into two phases, with phase 2 analysis only required if the tax measure is approved by voters. An oversight committee with prescribed membership must review and adopt the analysis for each phase, and transit operators must verify compliance as a condition of receiving funds.

The maintenance of effort requirement was consolidated into the Regional Network Management framework compliance section, requiring transit operators to comply with both the framework policies and a maintenance of effort requirement as conditions of receiving funds.

DEFINITION

New definitions were added for 'Commissioner,' 'County elections official,' 'District elections official' (with specific provisions for initiative petitions), 'Participating county transportation entity' (defining ACTC, CCTA, SFCTA, SMCTD, and SCVTA), and 'Subject operator.'
