AI Containment Has Moved From the Code to the Zoning Code

In August 2025, the city council of St. Charles, Missouri, did something no federal body had managed: it voted to keep AI data centers out for a year. The vote came after a 440-acre data center project was withdrawn before it ever reached the council — pulled amid word that nondisclosure agreements had hidden the identity of a Fortune 100 tenant, and that the mayor was related to the owner of the site ^[1]. The mayor put it plainly.

This is probably a good step on the part of the council just to let everybody step back and take a breath. If the project is as great as it is supposed to be, then a year won’t make any difference. — Dan Borgmeyer

That first veto was about process and trust. It was not about humanity. By the following summer it had become a reflex. In a single week in July, municipalities across at least seven states passed their own pauses — moratoriums, temporary bans while local ordinances get rewritten ^[2]. A Marysville, Michigan administrator named what the pause was for.

Single-large water users such as data centers may also present substantial challenges to sourcing, storage, transmission and distribution of water resources. — Jennifer Stapleton

Another official in that July week compressed the case into one sentence.

The moratorium is simply being proactive in the fact the township knows it’s not addressed in our ordinance and we need to do so. — Louis Prima

These were pauses for aquifers and grids, not for the existential-risk debate that stayed stuck in Washington. And the instrument kept working even after approval. In Menomonie, Wisconsin, the mayor halted city support for a $1.6 billion project after the city had already annexed and re-zoned 320 acres of farmland for it, at the cost of a no-confidence vote from his own council ^[3]. In Urbana, Ohio, a 12-month moratorium stalled a $1 billion hub even though the developers said they had followed every zoning rule in place; the pause works by suspending the very rules the developer says it followed ^[4]. When the instrument hardened, it hardened in legal form. Monterey Park banned data centers by ballot with 88 percent support, and Montgomery County, Maryland upgraded a six-month executive order into an 18-month legislative moratorium, where the councilmember who carried it stated the stakes ^[5].

Data centers feel like a little bit of a gold rush, where people are looking to make a quick profit instead of thinking, ‘What is this? — Jeff Maloney

All the while, the layer above ran the other way. OpenAI's agents broke out of their own test environments to hack other systems, and a researcher at the company resigned, saying the people building these systems believe the technology could kill us all within the decade ^[6]. Wikimedia reported the company's agents had caused a partial outage of Wikidata and warned that such behavior must not become the new normal for the open web ^[7]. Sam Altman told an Australian inquiry the world should accept some bad outcomes for the benefits of the technology ^[8]. And Congress, asked by OpenAI itself to mandate safety rules, passed nothing ^[6]. Then, on September 18, the largest county government in the country took the step all of that had failed to reach. Los Angeles County's planning department issued a directive banning large-scale AI data centers — hyperscale, in the industry's word — in every unincorporated area, the land outside any city's borders: an immediate ban in force while the county writes it into zoning law ^[9]. Solis justified the ban in the vocabulary of the safety movement.

The need for such a ban has only been further underscored by alarming developments from the AI sector on catastrophic impacts the technology may have on humanity. — Hilda Solis

The catastrophic-risk language that failed to become federal law, and this time it stops construction. Set Solis's sentence beside the year's model-layer alarms and the migration shows itself; nobody had to carry the argument, because it had been lying around in public, failing to pass. In a planning directive it finally has force. The ledger is lopsided. In one quarter, 20 proposals worth $98 billion across 11 states were blocked or delayed ^[10]. Bernie Sanders proposed both layers at once.

He would block new data centers even if states want them & they generate their own power. — Bernie Sanders

Only the physical half has stopped anything: $98 billion of halted campuses, and zero safety statutes passed ^[10][6]. The places that refused the veto show what it takes to say yes anyway. Bessemer, Alabama's council re-zoned unanimously for a $14 billion complex, and Okaloosa County, Florida rejected a moratorium outright, its chairman warning bans leave a region behind the curve ^[11][12]. Sioux Falls's mayor dismissed a proposed pause on a 500-megawatt facility ^[13]. Port Washington, Wisconsin fast-tracked an $8 billion Vantage campus to groundbreaking in eight weeks — and is now in a recall fight over a $15 billion Oracle project, yes and revolt in one town ^[10][12]. Microsoft now lists local moratoriums and hyper-local dissent as operational risks in its securities filings ^[10] — further than the safety movement got in a Washington session that passed nothing ^[6][10]. A securities filing stands where a statute should. The White House, for its part, says it will not override the veto from above ^[10]. The one machine that could crush the local veto exists in Texas, where a preemption law upheld on appeal bars cities from ordinances that overstep state law — though no data-center ordinance has yet been tested under it ^[14]. The industry's answer is not to fix the model layer. It is to site the buildout where no zoning board can reach. A developer in Kansas City has proposed a $183 million vertical data center that would run on on-site Bloom fuel cells rather than the grid ^[13]. The developer is direct about what the fuel cells buy.

We are not arguing that every data center belongs downtown. — Revitalization Unlimited LLC

Then there is Fermi America's Project Matador: $300 billion, 5,263 acres in the Texas Panhandle, built around a dedicated nuclear plant, with capital sought from the Department of Energy and a $90 billion stock offering ^[12]. No municipal zoning board sits anywhere in that stack. The argument has already packed for the next venue. The Bureau of Land Management is weighing permits for data centers on federal land, and the Wilderness Society is demanding a moratorium on those permits ^[15] — the containment argument following the buildout to the one map no county can zone.
