A new El Cerrito homeowner became a Nextdoor pariah over Measure C, the library parcel tax tied to the El Cerrito Plaza BART development. The essay is the hook; the civic fact underneath is that voters killed the measure June 2 — and the library it would have funded is now a contingent maybe.

In April, a couple bought their first house in El Cerrito. By the end of June, one of them was, by her own account, public enemy No. 1 on the town's Nextdoor.

That's the arc of an essay by Amy Brown, published August 5 in the Oakland Review of Books under the headline "How I became the villain of El Cerrito's Nextdoor." Brown describes herself as a compulsive poster and a low-level Nextdoor moderator — someone who reads the platform for entertainment, then made the mistake of forming an earnest opinion about municipal politics. She weighed in, not especially charitably, on the town's library ballot measure; she did it on Bluesky under her real name; word traveled back to Nextdoor. By her telling, it ended in a panic attack and an apology letter.

The essay is funny about a small town's capacity to argue with itself. Brown writes that more than 15,000 El Cerrito residents hold Nextdoor accounts, and that the grudges behind the library fight go back decades.

Underneath the online drama is a settled civic fact she walked into late: El Cerrito had already voted the thing down. Measure C, a 30-year parcel tax pegged at about 17 cents per square foot of built improvements, would have raised roughly $3.1 million a year to fund a new 20,000-square-foot public library on the ground floor of the mixed-use development rising at the El Cerrito Plaza BART station. It failed at the June 2 primary: 72.43 percent of voters said no, against 27.57 percent in favor, according to Contra Costa County results reported by KQED. Parcel taxes need a two-thirds supermajority to pass. A predecessor bond, Measure B in 2016, drew 63 percent and died the same way.

The library was never a sure thing anyway. The city's own planning documents describe it as an "opportunity" — a space the developer would build only if El Cerrito found the money to fit it out. Absent funding, that ground floor becomes about 2,000 square feet of retail and extra parking instead. The current library, at 6510 Stockton Avenue, opened in 1948; the county has trimmed its hours over the years, and the building fails seismic and accessibility codes.

The BART project keeps going regardless: 743 mostly-affordable homes across six phases on 6.5 acres of former parking lot, at the corner of Liberty and Fairmount, where crews broke ground late last year. Someone walking past the site tomorrow will see the housing go up. The reading room that was supposed to anchor it is, for now, a contingency the voters declined to fund — long after the Nextdoor thread had moved on.
