How a Neighborhood Dies

How the Damage Spreads

No one can point to the day a neighborhood died.

That is the hard part of this chapter, and it is the reason the thing it describes keeps happening. We saw in the highway chapter how East Tremont went from one of the nicer neighborhoods in the Bronx in 1948 to one of the most devastated places in America by 1980 — twenty-seven years, and not a single morning in all of them when you could have stood on the corner and said, today it ended. It went one softened property value, one departed family, one shuttered store at a time, each loss small enough to wave off, until the sum was a place that no longer existed.

The data center version runs slower and quieter than the highway version, because a data center doesn’t tear an expressway through your block. But it runs the same way and ends somewhere similar, and the mechanism is worth watching in motion — because the whole tragedy of it is that the trajectory is visible from the start, and almost nobody acts on it, since the early frames look nothing like the last one.

So here is the film.

It opens with an announcement — or, more and more often, with the discovery that there had been something to announce all along. Construction starts: the trucks, the dust, the closed streets, the trees coming down. People grit their teeth and wait it out, because construction ends. What they don’t yet know is that what comes after construction is the part that doesn’t.

The first people to leave are the ones who can. The young family already half-thinking about a bigger house; the couple who can work from anywhere. They read the coverage, they look at the thing rising at the end of the road, and they quietly decide to list now rather than later. Their houses sit a little longer than they would have a year ago and sell for a little less. Nobody calls that a crisis. It’s just a soft patch in the market.

Then the facility switches on, and the hum begins, and it does not stop. Some people stop hearing it within a week; some never do, and stop sleeping. The complaints to the city go nowhere, because the noise ordinance was written for backyard parties, not for a cooling system the size of a shopping mall running at three in the morning. A few neighbors sue. Most of those suits settle — often with a clause barring the people who settled from ever discussing it, so that when the next family wonders whether the noise is really as bad as they fear, the people who would know aren’t allowed to say. The neighborhood’s own memory gets edited as it goes.

A couple of years in, the electric bills start to climb, and the utility blames vague “supply costs” rather than the enormous new customer down the road. For a household with a little slack, the extra fifty or eighty dollars a month is an irritation. For a household with none, it’s a choice between the bill and something else that mattered. Some families cut the groceries. Some cut the medication. Some just go.

By the time the local school starts shedding students — the families with options have been trickling out for years now — the money follows the enrollment out the door, and the strongest teachers tend to leave first. The barber, the dry cleaner, the diner everyone used to walk to lose enough business that a few of them close, and each empty storefront makes the next one likelier. The dentist who’d been there thirty years retires, and nobody takes his place. The thing that made it a neighborhood — that everything was close, that you knew the people — quietly thins out.

And somewhere in here it tips into something self-sustaining. Buyers who can afford to look anywhere stop looking here, so the only buyers left are investors paying low prices to rent the houses out, and the owners who want to leave find the market won’t give them back what they paid. Deferred repairs make the block look tired, which makes it decline faster, because in real estate the appearance of decline is half its cause. Crime ticks up the way it does wherever fewer people who know each other are watching the street. Insurers raise premiums; banks grow wary of the mortgages; the buyer pool shrinks again. The grocery closes. The corridor fills with dollar stores and payday lenders.

Then one day someone says the neighborhood died, and they’re right — and there is still no day to point to. There was just twenty years of small decisions, none of them made by the people who lived there.

Every frame of that film has run before, somewhere, near some industrial siting decision of the last hundred years — the highways, the refineries, the petrochemical stretch of Louisiana that people started calling Cancer Alley, the waste plants, the prisons. The data centers are doing it on a gentler timeline, because they break less at the moment they’re built. The destination is the same.

I’m not claiming every neighborhood near a data center is bound for this. Some organize and stop the project outright. Some facilities are sited or designed so the cascade never catches. And a wealthy neighborhood with political capital can often have one as a neighbor and absorb it, because its residents have the resources to force the developer into the mitigations it would otherwise skip. The trajectory is the default, not the destiny. But the default is what runs when nothing interrupts it.

Here is the part worth sitting with: the early frames don’t look like collapse. Three years into the East Tremont story, in 1958, the neighborhood was still mostly itself — values a little soft, a few families gone, a couple of shops dark. It looked like a rough patch that would pass. It did not pass, and the damage done in those first years made the next years worse, and so on, until the highway had been there two decades and the place was gone.

Which means whatever leverage exists is front-loaded. By the time the bills are bad and the for-sale signs are sitting unsold, the people with options have already left and taken the capacity to do anything with them — so the only window in which the trajectory can still be bent is the early one, when the damage is least visible and therefore hardest to take seriously.

As of 2026 you can watch the same film at every frame at once: the residents of Brittany Heights in Arizona are eleven years in; Boxtown in Memphis is about two; Beaver Dam, Wisconsin, where Meta is just breaking ground, is at year zero. What’s striking, looking across them, is how rarely anyone living it could read the trajectory early enough to matter — precisely because the beginning never looks like the end.
