LEGISLATIVE COUNSEL'S DIGEST
AB 2484, Alvarez. San Diego Metropolitan Transit System: transactions and use tax: voter initiatives.
The Mills-Deddeh Transit Development Act establishes the San Diego Metropolitan Transit Development Board, also known as the San Diego Metropolitan Transit System (MTS), governed by a 15-member board with specified powers and duties related to the operation of public transit services in the southern portion of the County of San Diego. The act authorizes MTS to impose a transactions and use tax of up to 0.5% for public transit purposes within its jurisdiction, or a portion of its jurisdiction, pursuant to the Transactions and Use Tax Law and subject to voter approval and various other requirements.
This bill would also authorize those taxes to be imposed by a qualified voter initiative. To the extent that the bill would impose additional duties on a county elections official, the bill would impose a state-mandated local program.
The Transactions and Use Tax Law limits the combined rate of all taxes that may be imposed in accordance with that law in any county to 2%.
This bill would prohibit the tax rate of 0.5% described above that may be imposed by MTS or a qualified voter initiative from being considered for purposes of the combined rate limit under the Transactions and Use Tax Law.
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.
The people of the State of California do enact as follows:
SECTION 1.
The Legislature finds and declares all of the following:(a) The San Diego Metropolitan Transit System, also referred to as MTS, provides public transit services to the urbanized areas of the County of San Diego, including 10 cities and a portion of the unincorporated areas of the county, serving approximately 3,000,000 people in the County of San Diego.
(b) MTS connects to other local and regional transportation systems in southern California.
(c) The MTS transit network is a critical component of the overall transportation network in the County of San Diego, and as such MTS has aggressively taken steps to improve and optimize public transportation for the benefit of all communities in the County of San Diego.
(d) Through these improvements, MTS has realized a strong transit ridership recovery, having recovered more than 95 percent of its ridership compared to pre-COVID-19 levels and recording 81.1 million trips in the 2025–26 fiscal year.
(e) MTS has prioritized ridership recovery lost from the COVID-19 pandemic, rising eight spots nationwide to the 13th ranked system on ridership as of the 2025–26 fiscal year.
(f) While MTS has seen success and ridership growth since the COVID-19 pandemic, it is still experiencing a structural deficit and approaching what is commonly known as the transit fiscal cliff in 2030.
(g) Since the COVID-19 pandemic, MTS has seen the onset of a fiscal cliff due to reasons such as regaining lost ridership from the pandemic, rising workforce costs, higher operating expenses, flat sales tax revenues, and limited local funding.
(h) MTS has developed a comprehensive financial sustainability strategy to delay its fiscal cliff to the 2030–31 fiscal year. This includes delaying noncritical infrastructure improvements, finding more sources of nonfare revenue, such as advertising and property leases, extending timelines for pension bond payments, exploring fare increase opportunities, and more.
(i) Also, as part of the financial sustainability strategy, MTS is pursuing a Comprehensive Operational Analysis to analyze MTS services and to provide strategic data necessary for making decisions on major network changes, while also exploring viability of a local revenue measure in 2028.
(j) The County of San Diego is at the forefront of housing expansion and leads the state in housing production per capita. MTS has contributed to regional housing goals in the County of San Diego with its own Transit-Oriented Development Program with a focus on affordable housing. MTS has built 476 homes since 2019, is under construction on 79 homes, has 147 homes at the permitting and financing stage, and has 929 homes in the negotiation stage.
(k) Continuing this housing growth requires robust transit service to match and ultimately grow with the region to sustain the needs of its residents, particularly those who are transit dependent, of which 78 percent of MTS ridership is classified.
(l) Public transit is of regional and local benefit, serving both regional and local trips for residents of all income levels. As of the most recent customer survey, more than two-thirds of current MTS riders are using bus and trolley services primarily to access jobs or education.
(m) MTS plays a vital role in transportation access to major events, conventions, and sports and entertainment venues in the San Diego region, including Comic-Con, Snapdragon Stadium, and Petco Park, enabling residents, workers, and visitors to attend sporting events and other large-scale gatherings while reducing traffic congestion, parking demand, and greenhouse gas emissions. In the 2025–26 fiscal year, MTS provided roughly over 1,000,000 trips to special events in the San Diego region.
(n) The County of San Diego needs a world-class, reliable, affordable, and connected transportation network that meets the needs of San Diego residents, businesses, and visitors while also helping combat the climate crisis. Furthermore, MTS serves as a critical binational economic connector between the United States and Mexico at the busiest land port of entry in the Western Hemisphere. MTS carries more than one-half of the pedestrians crossing every day at the Otay Mesa and San Ysidro ports of entry.
(o) The County of San Diego needs a public transit network that offers safe, clean, frequent, accessible, easy-to-navigate, and reliable service that gets transit riders where they want and need to go safely, affordably, quickly, and seamlessly.
(p) Preserving, improving, and expanding public transit to ensure a world-class transit network is critical to enhance access to opportunity, lower emissions of greenhouse gases, strengthen the region’s economy, support increased housing production, and improve quality of life.
(q) To achieve these goals, local funding is critical to sustaining and improving public transit service in the County of San Diego for future generations to come.
(r) This act is critical to ensure ample time for planning and preparation in advance of a local funding initiative effort.
