"You can't replace trees, not oaks, not in our lifetime, it takes hundreds of years to grow those trees." That's what one resident told the San Carlos School District board this spring, watching plans take shape to clear protected oaks from Arundel Elementary's lower yard. It's a small fight inside a much bigger story, one playing out at four campuses across town this year, and it tells you something about San Carlos that no median-price chart will.
Under Measure H, a $176 million school facilities bond that voters approved in 2024, the district broke ground this year on construction at Arundel, Brittan Acres, and Heather elementary schools, all within the same stretch of months. A fourth campus, White Oaks Elementary, closed its front office the same week in June for its own construction project. That's a lot of chain-link fencing to hit at once, and the reason has less to do with aging buildings than with a trend almost no other district in the county is dealing with right now.
The County Is Shrinking. San Carlos Isn't.
Most San Mateo County school districts have spent the past several years managing decline, fewer kids enrolling, fewer classrooms needed, budgets shaped around shrinking rolls. San Carlos is running the opposite playbook. Reporting on the district's construction rollout noted it is one of the only districts in the county still seeing enrollment climb while its neighbors document losses. Board President Sarah Kinahan put the underlying problem plainly, calling the need for classrooms and additional space significant.
That single fact explains the timing better than any bond measure summary could. A shrinking district can space capital projects out over a decade and still keep up. A growing one can't. The classrooms need to exist before the kids who'll sit in them arrive, which is why San Carlos is running three groundbreakings in parallel instead of staggering them the way a more comfortable district might.
Four Campuses, Four Different Scopes
The projects aren't identical, and the differences are worth knowing if you have a kid zoned to one of these schools this fall.
- Arundel Elementary is getting four new transitional-kindergarten classrooms, new playground equipment, accessible paths, and a designated route for emergency vehicles.
- Heather Elementary is getting eight new classrooms, the largest single expansion of the three campuses that broke ground this year.
- Brittan Acres Elementary is getting two new classrooms.
- White Oaks Elementary closed its office on June 13 alongside Brittan Acres and Heather for its own campus construction project. The district hasn't published a detailed scope for that one yet, but the timing lines it up with the same wave of work.
Eight new classrooms at Heather versus two at Brittan Acres isn't a rounding difference. It's the district telling you, through where it's spending bond money, which attendance area is absorbing the most growth pressure right now.
What the Calendar Actually Looks Like
School offices reopened August 10 after the summer closure, and the district's approved 2026-27 calendar has students back on campus starting August 19, a minimum day.
| Date | What's happening |
|---|---|
| Aug 13-14 | Teacher professional development / work days |
| Aug 17-18 | Teacher professional development / work days |
| Aug 19 | First day of school (minimum day) |
Projects of this size, new classroom wings, regraded playgrounds, rerouted access paths, don't wrap up over a single summer. Families at Arundel, Brittan Acres, Heather, and White Oaks should expect the fencing and equipment to still be visible well into the fall semester, not just cleared away before the first bell.
The Oak Tree Question at Arundel
The most concrete friction point sits at Arundel. To make room for the four new TK classrooms, the district's construction plan calls for removing eight protected oak trees from the school's lower yard, while trees in the upper play area are meant to be preserved. At a community meeting this spring, nearby neighbors said they felt caught off guard by how far along the plans already were.
One resident, Gary Barth, told the district that trees lining his own driveway are among those slated for removal, and said he'd consider legal action if the project moves forward as currently designed. It's a reminder that a bond measure passed by a citywide vote and a construction plan that touches a specific backyard are two very different experiences of the same project. The oaks are the part of "district growth" that shows up on somebody's actual property line.
Where to Follow the Money and the Timeline
If you want more than secondhand updates, the district's Measure H spending runs through an Independent Citizens' Bond Oversight Committee, and its next meeting is scheduled for September 9, 2026, at 5:30 p.m., held at Brittan Acres Elementary. That's not a coincidence. Holding the meeting at one of the active construction sites means residents can sit in the room where the work is actually happening and ask questions directly.
The committee is also currently recruiting two new members, one who's active in a senior citizens' organization and one active in a business organization representing the local business community. It's a low-friction way to get a closer look at how bond dollars are actually being spent, beyond whatever shows up in a district newsletter.
For the day-to-day basics, first-day dates, minimum days, and the rest of the year's calendar, the district keeps its official 2026-27 calendar posted here, and the San Mateo Daily Journal's coverage of the groundbreakings and the Arundel tree dispute is worth reading in full if you want the neighbor-level detail.
The Real Story Isn't the Fencing
It's tempting to read all this as a maintenance story, old schools getting a refresh. The more accurate read is that San Carlos is one of the few places in the county still adding families fast enough to need eight new classrooms at one campus and four more at another, in the same construction season. That's the kind of demand signal that doesn't show up in a monthly housing report, but it shows up at drop-off, in playground closures, and in a fight over eight oak trees that a lot of San Carlos families are about to watch play out in real time.
