San Mateo Mayor Adam Loraine is fighting to keep his District 5 council seat this November against two challengers who want to steer city hall in very different directions. The race, which covers a southwest portion of San Mateo, has turned into a referendum on how the city should close a nearly $17 million budget deficit, handle a years-long bike lane dispute, and manage a wave of development near Caltrain. Loraine faces off against Dana Yates Sahae and Dave Johnson, both longtime San Mateo residents, in what will be only the second election since the city moved away from citywide, at-large council voting.
Loraine was first elected to the council representing District 5 in December 2022, during San Mateo's inaugural by-district election, and has since served as Deputy Mayor in 2025 and is now Mayor, according to the City of San Mateo. His career at professional services firm ZS has involved strategic growth, social impact, and sustainability initiatives; ZS focuses on transforming global healthcare. He is notably the only tenant on the five-member council, a distinction that has shaped his stance on several housing and development fights. The San Mateo Daily Journal reported that Loraine supports the Hillsdale redevelopment and has discussed a fiscal sustainability plan if the tax fails.
The challengers differ on several city issues. Sahae generally supports Measure H and favors requiring property-owner consent before new historic designations, with select exceptions. Johnson is leaning against Measure H for now and favors removing the Humboldt Street bike lanes and restoring the lost parking.
The Sales Tax Fight at the Center of the Race
The clearest divide in the race is over Measure H, the city's proposed sales tax increase meant to help close a budget gap the San Mateo Daily Journal reports at nearly $17 million, based on June estimates. The city describes it as a quarter-cent transactions and use tax expected to generate roughly $7 million annually for general municipal services, according to the City of San Mateo. Potential priorities include 9-1-1 response, street and sewer maintenance, parks and libraries, and emergency preparedness. The San Mateo Daily Journal also describes the council-approved measure as a quarter-cent tax.
Loraine favors the tax, while Sahae reluctantly supports it; Johnson is leaning against it for now as part of his fiscal-conservatism stance. Hoodline reported that neighborhood outreach meetings on the measure were scheduled for June 2026 in its coverage of San Mateo City Boss Hits Neighborhood Circuit.
Bike Lanes and Historic Homes Divide Candidates
Few local issues have generated as much neighborhood friction as the Humboldt Street bike lanes, installed in 2022 after roughly 200 parking spaces were removed in North Central San Mateo. The lanes have remained a point of debate. Johnson favors permanently removing them and restoring the lost parking, a position that puts him at odds with those who want the lanes retained.
The council has also wrestled with historic preservation rules that split the current council. Members approved updates requiring property-owner consent for new historic designations while also creating a process letting the city designate certain prominent properties as historic, according to the San Mateo Daily Journal. The council voted 3-2 to fund a survey identifying historic structures citywide, with Loraine voting no. Sahae generally supports requiring property-owner consent for new historic designations, while allowing select properties to be designated regardless of ownership, positioning her closer to preservation critics on that issue even as she aligns with Loraine on the sales tax.
Transit-Oriented Development Looms Over District 5
Much of District 5's future is tied up in what happens near the Hillsdale Caltrain Station, where the city is weighing redevelopment of the aging Hillsdale Shopping Center. The proposed “Hillsdale Reimagined” master plan, filed by Bohannon Companies and Northwood Investors, calls for replacing three-quarters of the 71-year-old, 44.7-acre mall with a transit-oriented village of roughly 1,350 to 1,400 housing units alongside office space and retail, according to The Real Deal. The plan followed local voter approval of updated density and height standards for the site.
Voters in District 5 will decide the race alongside contests in Districts 1 and 3 when San Mateo holds its municipal election on Tuesday in November, marking just the second time the city has elected council members through district-based voting rather than its previous citywide system. With a budget deficit, a contested sales tax, and competing visions for growth all on the table, the outcome could shape how San Mateo balances development pressure against neighborhood pushback for years to come.
