We Caught the Bus! Retaking Bay Area Public Transit

Peninsula DSA organizers rallied on July 1 at Millbrae Transit Center with riders and advocates from Transbay Coalition, Seamless Bay Area, Faith in Action Bay Area, Silicon Valley Bike Coalition, Housing Leadership Council of San Mateo County, 350 Silicon Valley and Sustainable San Mateo County to demand the decision-makers at SamTrans "opt in" San Mateo County to the regional transit funding measure (Wiener & Arreguín's SB 63).

San Mateo County Opts In to Regional Funding Measure

Follow-up to Get on the Bus: Retaking Bay Area Public Transit

Bay Area public transit notched a generational win for operational funding thanks to grassroots organizers and transit advocates. Throughout 2025, Peninsula DSA (PDSA) in suburban San Mateo County engaged transit riders and activists to save light rail Bay Area Rapid Transit (BART, 178,000 weekday riders) and commuter rail Caltrain (37,000 weekday riders) from looming fiscal cliffs and severe service cuts. 

In partnership with Transbay Coalition, PDSA organizers reached people via many channels, including PDSA’s social media; flyering BART and Caltrain stations and talking to riders; posting to r/BART and r/Caltrain on Reddit; mobilizing PDSA chapter members via email, text messages, and our own Discord server; and a successful coalition rally during rush hour at a major transit hub in Millbrae. Our underlying message to transit riders? Demand San Mateo County opt in to SB 63!

PDSA identified SB 63, Senator Scott Weiner (District 11) and Senator Jesse Arreguín (District 7)’s 2026 five-county regional funding measure, as a priority campaign for our chapter. The Senate bill authorizes a 2026 citizens ballot initiative campaign to raise new funds to sustain BART, Caltrain, Muni (San Francisco), and other transit agencies in the Bay Area as they continue to recover their pre-COVID ridership. The tens of millions of dollars in new dedicated revenue would save these fixed-rail operators from massive service cuts that would render them virtually unusable.

The importance of maximum funding

But of course there’s a catch: Politicians chose to give both Santa Clara County and San Mateo County, the two wealthiest counties of the five, the option to decline to participate in the group project or opt in at a lower tax rate than the other three counties. Transit riders like us immediately understood exactly how important it is to get maximum funding for our county, which relies on Caltrain for more than just Giants games and has six BART stations, including an essential stop at San Francisco International Airport (SFO). 

But transit riders aren’t the decision makers in San Mateo County. That’d be SamTrans, the county-wide bus system, or more specifically, the nine members of the Board of Directors. To save BART and Caltrain, PDSA members and allies attended the monthly SamTrans Board of Directors meetings to push them to think beyond San Mateo County’s borders and invest in regional transit for the people through SB 63. Our consistent pressure tactic—whether in person, via Zoom, or by email—was making well-coordinated public comments in support of opting in to a progressively funded regional funding measure. 

Comrades and allies used our time at the podium to share personal transit stories and educate the Board members, most of whom never use transit, on how transit cuts would negatively impact local SamTrans riders and San Mateo County residents. We also took the opportunity to push for funding SB 63 with a gross receipts tax (0.112% tax on the top 2% of businesses) instead of a regular regressive sales tax (of ¼ or ½ cent) that would hit low-income SamTrans riders the hardest. 

Final Showdown with SamTrans

The August 6 SamTrans Board meeting, when the Directors voted on SB 63, was highly unusual. Chair Jeff Gee refused to hear or discuss any public comments focused on the gross receipts tax, despite the hundreds of emails on that topic that we had encouraged transit riders to send to the Board of Supervisors and other influential political bodies. PDSA member Marc S used his public comment to gesture to gross receipts anyway: “The proposed sales tax, compared to other tax options, might not even prevent all cuts. Participating in SB 63 today is the bare minimum [to] address the San Mateo County residents' need for affordable, safe, and equitable transit both within the county and around the Bay Area.”

In the eleventh hour, California Assemblymember Diane Papan was given the floor and used her time to advertise her own overreaching amendment to SB 63 that called for “accountability” regarding how other counties would spend the funds at their transit agencies, while repeating misinformation about how BART operates and railing against “taxation without representation”—the Boston Tea Party was mentioned. (Note: San Mateo County would already have a seat on BART’s Board of Directors, and the vote and oversight Papan desires, if politicians hadn’t opted out of the network in the 1960s!) “The fiscally conservative rhetoric came from the fact that none of these board members seem to know there are citizens of San Mateo County who rely on transit to get around,” said Becca W, a PDSA member who publicly commented. “But now with this public pressure, they are well aware.” 

Even so, PDSA’s s organizing efforts paid off. The SamTrans Board voted 8-1 to opt in to SB 63 to raise new revenue to fund the transit agencies in the five-county Bay Area: Alameda, Contra Costa, San Mateo, Santa Clara, and San Francisco. (The one dissenting vote was Jackie Speier.) SamTrans opted in at the higher ½ cent sales tax rate, a huge win considering they had been leaning toward opting out of the measure before our campaign kicked into gear. The public records of their official correspondence shows SamTrans received more than a hundred emailed public comments specifically in support of SB 63, exceeding their average inbox haul by a factor of ten.

Coordinated Public Transit Is the Way Forward

Assuming the citizens’ ballot measure is approved by a simple majority of voters in November 2026, the five-county Bay Area will have a new shared revenue source for maintaining current levels of service for public transit. Because Bay Area residents and visitors cross county borders all the time, it only makes sense that we plan and fund projects together. Robust public transit networks will be key in building a green future where a polluting private car is no longer the only viable option for getting around San Mateo County. 

Of course, with inflation and tariffs, even more money will be necessary if transit operators are to deliver faster, rider-friendly, affordable, and coordinated service around the region. Though the gross receipts tax didn’t make it into the final bill, keeping Bay Area transit operational with an assist from wealthy San Mateo County allows PDSA organizers the space and time to plan our next strategic move to win better (and eventually free!) transit for all.
