Contra Costa County voters delivered a split decision in the June 2 primary, overwhelmingly renewing the county’s anti-sprawl Urban Limit Line while rejecting a proposed half-cent sales tax intended to shore up the local healthcare system. For Walnut Creek residents, the results — still being tallied as late mail-in ballots arrive at the registrar’s office — signal a clear message about what voters will and won’t pay for in an era of rising costs and federal budget uncertainty.
Three countywide measures and a Walnut Creek school parcel tax dominated the local ballot, each carrying distinct implications for daily life in the East Bay’s retail and dining hub. With roughly 24% of the potential vote counted as of early Wednesday morning, trends have solidified enough to draw preliminary conclusions — though final certified results from the Contra Costa County Registrar of Voters won’t arrive for several days as remaining ballots are processed.
Measure A: Urban Limit Line Renewed by Wide Margin
Voters once again backed the county’s decades-old growth boundary, with Measure A receiving 67.91% support in early returns. The measure extends the Urban Limit Line through 2051, maintaining the policy’s 65/35 land preservation standard — roughly 65% of county land preserved as open space, with 35% available for urban development.
The Urban Limit Line has been on the books since 1990 and was last renewed by voters in 2006. By channeling development toward existing infrastructure and transit corridors — including BART stations like Walnut Creek’s — the policy aims to prevent the kind of suburban sprawl that would increase greenhouse gas emissions and strain county services. The measure was largely noncontroversial through its 36-year history, having been adjusted six times with minimal opposition.
This cycle, however, the Contra Costa Taxpayers Association mounted a campaign against Measure A, arguing the limits would hamper new home construction at a time when California faces a severe housing shortage. Association President Marc Joffe acknowledged the uphill nature of the fight: “Residents of Contra Costa County value their open space.” Under the new boundaries, approximately 11,100 acres of currently developable land would shift to the protected side of the line, while 1,600 acres would be added to the developable side — a net reduction of about 9,460 buildable acres, most of which officials say is already on steep terrain, in fire zones, or being converted to public parkland.
Measure B: Healthcare Tax Goes Down Decisively
If Measure A was a landslide, Measure B was a rout in the opposite direction. The proposed 0.625% general retail sales tax, which would have raised roughly $150 million annually over five years for county healthcare, was trailing with 59.04% opposed and 40.96% in support in preliminary returns.
County supervisors placed Measure B on the ballot to offset what interim CFO Brian Buchanan described as looming budget catastrophe: approximately $500 million in reductions to the county health system and a projected $1 billion deficit by 2031. The pressure comes from multiple directions — a state budget deficit, plus $1 trillion in federal Medicaid cuts over a decade approved under the Republican-backed HR1. Provisions under that bill don’t take effect until 2027 or later, but county officials argued they needed to act now.
Opponents, led by Joffe and the Contra Costa Taxpayers Association, countered that the county has a spending problem rather than a revenue shortfall, noting that Measure B revenue would flow into the general fund and could be used for any county expense — not specifically healthcare. They also argued some federal and state cuts are likely to be reversed or mitigated by upcoming legislation, including a proposed 5% wealth tax on California billionaires.
Supervisor John Gioia didn’t sugarcoat the consequences. “There’s no way to sugar coat this, the failure to pass this measure will result in more people losing healthcare and more people going to the emergency room,” Gioia said. “It’s not if the cuts will happen, it’s when.”
The 0.625% sales tax would have added 6.25 cents to every $10 purchase in Contra Costa County, generating about $150 million per year. Collections would have started this fall. The county already has Measure X, a half-cent sales tax approved in 2020 for health services and emergency programs. With Measure B’s failure, county supervisors say they will need to “figure out how to survive the cuts” using existing resources.
School Measures: Mixed Results Across the Region
Bay Area voters faced more than $688 million in school bond and parcel tax measures on June 2 ballots, and the results paint a fractured picture. While wealthier communities like Piedmont (Measure H) and Moraga (Measure I) saw their measures passing comfortably, many districts serving working-class families trailed or fell short.
Walnut Creek School District’s Measure L, a $98 annual parcel tax for nine years to attract and retain teachers, fund academic programs, and maintain class sizes, was trailing in early returns. The measure required two-thirds approval to pass. Acalanes Union High School District had no measure on this ballot, but MDUSD families were watching results closely given the district’s financial pressures from declining enrollment and rising costs.
Across the Bay Area, the pattern was consistent: Lafayette’s Measure H ($585 per parcel) was passing by a wide margin, as was Moraga’s Measure I ($295 per parcel). But Castro Valley’s $212 million bond was losing narrowly, Hayward’s Measure G was trailing by a wider margin, and both of Oakley’s school bond measures were behind. In Palo Alto, a $800-per-parcel renewal tax was losing by a narrow margin.
The common thread: districts in more affluent areas found the supermajority thresholds easier to clear, while those in communities with tighter household budgets struggled — even when the per-parcel ask was modest by comparison.
| Measure | District | Amount | Status | Threshold |
|---|---|---|---|---|
| Measure L | Walnut Creek SD | $98/parcel × 9 yrs | Trailing | 66.7% |
| Measure H | Lafayette SD | $585/parcel × 9 yrs | Passing | 66.7% |
| Measure I | Moraga SD | $295/parcel × 7 yrs | Passing | 66.7% |
| Measure B | Castro Valley USD | $212M bond | Trailing (narrow) | 55% |
| Measure B | Palo Alto USD | $800/parcel × 4 yrs | Trailing (narrow) | 66.7% |
| Measure H | Piedmont USD | $3,174/parcel × renewal | Passing (wide) | 66.7% |
What It Means for Walnut Creek
The split outcome — yes to open space, no to taxes — reflects a broader tension in Contra Costa County politics. Voters value public goods: protected open space, quality schools, a functional healthcare safety net. But in an era of persistent inflation, rising insurance costs, and uncertainty about federal funding, willingness to open wallets has limits.
For Walnut Creek specifically, the Urban Limit Line renewal reinforces the development pattern the city has pursued for decades: concentrated growth near BART and downtown, with the surrounding hills and open spaces preserved. That’s likely to intensify pressure for transit-oriented development around the Walnut Creek BART station, where plans for mixed-use housing have been in the works.
The failure of Measure B means the county health system faces $500 million in cuts without a dedicated local funding stream to backfill. For Walnut Creek residents who rely on Contra Costa Health Services — including those at Contra Costa Regional Medical Center in Martinez — the consequences will become clearer as HR1 provisions phase in starting in 2027. Supervisor Gioia’s warning that “real people” will feel “real” pain is the backdrop against which future county budget negotiations will unfold.
As for Walnut Creek schools, the fate of Measure L will determine whether the district can maintain current teacher staffing levels and class sizes, or whether cuts will follow the pattern seen in other Bay Area districts that couldn’t clear the two-thirds threshold. Final results are expected as the registrar continues counting late-arriving ballots through the end of this week. Results are posted at the Contra Costa County election results page, with statewide context available from the California Secretary of State.
What Happens Next
Ballots postmarked by June 2 and received within seven days are still being counted. Signature verification can flag ballots for curing — a process where voters are contacted to confirm their identity — meaning some close races could shift as final tallies come in. The Contra Costa County Registrar of Voters expects to release updated counts daily through the end of the week.
Measure A’s wide margin makes its passage effectively certain regardless of remaining ballots. Measure B’s deficit appears insurmountable. But the school parcel tax races, including Walnut Creek’s Measure L and Palo Alto’s Measure B, could still tip if late ballots trend favorably. For families watching those counts, the coming days will determine whether local classrooms keep their teachers or face the cuts already underway across much of California’s public education system.
