The San Diego Association of Governments (SANDAG) is the council of governments and metropolitan planning organization (MPO) for the San Diego region of California. It is a joint-powers agency whose members are San Diego County and its 18 incorporated cities, and it is governed by a 21-seat Board of Directors of mayors, city councilmembers, and county supervisors drawn from those jurisdictions.

In addition to its role as the region's MPO, SANDAG serves as the regional transportation planning agency (RTPA), San Diego County Regional Transportation Commission, regional toll authority, and the agency responsible for the Regional Housing Needs Assessment for San Diego County. It administers TransNet, a countywide half-cent sales tax for transportation, and has shared capital-planning and fare-setting authority over the region's two public-transit agencies: the San Diego Metropolitan Transit System (MTS) and the North County Transit District (NCTD).

SANDAG and the Southern California Association of Governments are the two MPOs serving Southern California. The agency had an adopted budget of approximately $1.3 billion for fiscal year 2026 and employs roughly 400 staff serving a region of about 3.3 million residents.

In 1987, San Diego County voters approved TransNet, a 20-year half-cent sales tax dedicated to transportation. Voters extended the tax in 2004 through 2048, and TransNet has since provided the local funding base for a significant share of the region's highway, transit, bikeway, and local-street investments.

In 2003, the California State Legislature consolidated the transit-planning and capital-project-development functions of MTS and NCTD within SANDAG, leaving day-to-day transit operations with the two transit agencies.

Leadership

In January 2025, the board unanimously elected Solana Beach Mayor Lesa Heebner to a two-year term as Chair, with San Diego City Council President Joe LaCava as First Vice Chair and Santee Mayor John Minto as Second Vice Chair. Heebner succeeded former county Supervisor Nora Vargas, who chaired the board from early 2023 until her abrupt resignation from the Board of Supervisors in late December 2024.

The day-to-day operations of the agency are led by a Chief Executive Officer, who reports to the Board. Gary Gallegos served as executive director from 2001 until his 2017 resignation amid a forecasting scandal. From December 2018 until his resignation effective December 29, 2023, the agency was led by Hasan Ikhrata, who made transit expansion and a proposed per-mile road-usage charge the centerpieces of the 2021 Regional Plan. Deputy CEO Coleen Clementson served as interim chief executive during the 2024 recruitment.

Following a national search, the Board selected Mario Orso, then the Chief Deputy Director of Caltrans District 11, as CEO on April 26, 2024. Orso, a 32-year Caltrans veteran, began a three-year contract on June 17, 2024, with a starting salary of $385,000 and a six-year option. Shortly after taking office, Orso dismissed Deputy CEO and chief economist Ray Major and eliminated the agency's deputy-CEO positions as part of a broader restructuring.

Policy Advisory Committees

The Board delegates responsibility to six Policy Advisory Committees that oversee specific subject areas: the Executive, Transportation, Regional Planning, Borders, Public Safety, and Audit committees. All items delegated to the committees are subject to ratification by the full Board.

AB 805 and governance reform

A 2017 investigation by Voice of San Diego revealed that SANDAG staff had overstated revenue projections and understated project costs for the 2004 TransNet extension and for the 2016 Measure A sales-tax increase that voters narrowly rejected. The disclosures prompted the resignation of longtime executive director Gary Gallegos and led to the introduction of Assembly Bill 805 by Assemblywoman Lorena Gonzalez Fletcher of San Diego.

Signed into law by Governor Jerry Brown on October 11, 2017, AB 805 restructured the weighted-vote process, required the agency to hire an independent performance auditor, and authorized MTS and NCTD to place their own sales tax measures on the ballot. The changes shifted the board's political center of gravity toward the region's larger and more urban cities.

The 2021 Regional Plan, adopted in December 2021 at an estimated cost of $163 billion through 2050, envisioned an expansion of light rail and rapid bus services, a transit connection to San Diego International Airport, relocation of the LOSSAN rail corridor off the eroding Del Mar bluffs, and the eventual imposition of a four-cents-per-mile Regional Road Usage Charge beginning in 2030. The plan polarized the board, and in September 2023 the Board voted 15 to 4 to formally remove the mileage fee from the plan's framework.

On December 12, 2025, the Board adopted the 2025 Regional Plan and certified its accompanying environmental impact report. With an implementation cost of approximately $125 billion through 2050, the 2025 plan is considerably more fiscally constrained than its predecessor: it relies primarily on bus rapid transit, managed lanes, and on-demand flexible-fleet service; scales back the proposed Purple Line light rail to end in Mission Valley rather than Sorrento Valley; and assumes less federal funding than the 2021 Plan. The plan targets a 19 percent reduction in transportation-sector greenhouse-gas emissions by 2035, measured against 2005 levels.

Funding

About three-quarters of SANDAG's annual operating revenue comes from state and federal grants, with the remainder generated by TransNet, tolls, and other local sources.

Fare payment systems

SANDAG launched the Compass Card in May 2009 as a regional contactless smart card integrating fare payment across MTS and NCTD services. It was replaced on September 1, 2021, by Pronto, an account-based system operated by INIT and jointly administered by MTS and SANDAG. Pronto introduced a Best Fare fare capping feature and expanded mobile-app payment.

In May 2022, SANDAG launched the Youth Opportunity Pass, a pilot program that provides free MTS and NCTD transit for anyone 18 or younger with a registered Pronto account. The pilot, which had distributed more than 32 million free rides by late 2024, has been extended through June 30, 2026.

SR 125 toll-road overcharges

In November 2023, former SANDAG director of accounting and finance Lauren Warrem filed a whistleblower lawsuit alleging that SANDAG had wrongfully terminated her for raising concerns about systemic billing errors in the SR 125 toll-road accounting system operated by the vendor ETAN Tolling Technology. Warrem estimated that as many as 45,000 driver accounts had been mischarged.

A March 2024 report by SANDAG's Office of the Independent Performance Auditor concluded that ETAN's Fastlane back-office financial reporting was unreliable and that the agency's finance department lacked adequate internal controls. The auditor estimated the agency had lost at least $3 million in toll revenue due to the system's failures. An October 2024 follow-up investigation concluded that Ikhrata, CFO Andre Douzdjian, and other senior managers had been aware of the problems for more than a year before informing the Board.

The board subsequently replaced ETAN with Deloitte and A-to-Be and adopted the auditor's ten recommendations. Chula Vista and several South Bay elected officials called for the elimination of tolls on SR 125, though no vote to do so had been scheduled as of early 2026.

ARJIS data-sharing with federal immigration agencies

In January 2026, news reports revealed that the U.S. Customs and Border Protection (CBP) and Homeland Security Investigations (HSI) paid SANDAG approximately $100,000 annually for access to the Automated Regional Justice Information System (ARJIS), the regional law-enforcement database that aggregates traffic citations, arrests, field interviews, and limited driver's-license information from local police agencies. Although CBP is contractually prohibited from using the data for civil immigration enforcement, advocates and several board members raised concerns that SANDAG lacked independent authority to audit federal usage and that no compliance audit had been completed since 2017.

At the Board's January 29, 2026 meeting, San Diego City Councilmember Vivian Moreno called on SANDAG to terminate the federal contracts; County Supervisor Paloma Aguirre questioned whether ARJIS member agencies could be confirmed in compliance with California's Values Act (SB 54). The Board directed staff to return with options for tightening oversight, and the issue remained unresolved as of April 2026.
