A Federal Judge Dismissed DC Blox's Lawsuit Against Nashville. The City's Own Zoning Staff Say Its Data Center Permits Are Vested Anyway.

Rick Schwartz runs the Nashville Zoo, and the way he tells it, he isn't opposed to data centers as a category. He's opposed to one in particular. "I'm not against data centers, but they should not be located by the number one attraction in the Nashville community," Schwartz said this spring, after a Georgia-based company called DC Blox closed on 23.49 acres next door to his zoo for $23 million. His specific worry is the animals: the zoo's clouded leopards and other sensitive species, kept on carefully managed light and sound cycles. "The noise pollution, the light pollution, all of those things affect animals, affect their photo periods, affect their life cycles," he said. More than 391,000 people eventually signed a petition echoing him, and 245 residents signed up to speak against the project at a single Metro Courthouse hearing.

The deal itself was straightforward when it closed on July 17th. DC Blox bought the Grassmere Park parcel, at 648 Grassmere Park Drive, planning a roughly 10-megawatt facility of about 69,220 square feet, sited directly beside the zoo's property line. DC Blox is not a stranger to this kind of build; the company already operates data centers elsewhere in the Southeast. What made this site different was the neighbor, and the neighbor had a petition drive and a quarter-million signatures within weeks.

DC Blox didn't ignore the backlash. The company offered a contractual sound limit of 65 decibels at the property line, proposed funding an acoustic study tailored to the zoo's most sensitive animals, and committed to closed-loop or waterless cooling to limit water draw. Those are real concessions, the kind this blog usually treats as evidence a developer is taking a neighbor's objection seriously rather than just weathering it. They didn't move the opposition. By June, hundreds of residents were showing up to council hearings, and Nashville Zoo had become, as one outlet put it, a surprisingly formidable opponent for a data center company to have made.

The city moved on three fronts at once

Nashville's Metro Council didn't settle for one tool. On July 21st, it voted unanimously to pass two things at once: a moratorium freezing all data center permits through December 1st, and a permanent zoning overhaul banning any data center over 500,000 square feet, requiring a public hearing and special-exception process for smaller ones, and mandating 100-foot buffers from homes, schools, churches, and zoos. The sponsor was Councilmember Courtney Johnston, whose district includes the zoo.

Two weeks later, the council went further. On August 4th, it voted 27-5 to authorize Mayor Freddie O'Connell's plan to acquire the Grassmere Park site by eminent domain -- not to regulate DC Blox's project, but to take the land outright for public use. Davidson County's own assessment puts the parcel's value near $37 million, roughly $14 million above what DC Blox paid for it two months earlier, which means condemning it could cost Nashville taxpayers meaningfully more than the company's own purchase price. Johnston, defending the move, said the council was using "every tool in the toolbox." It's a candid way to describe it. A city using eminent domain to block a legally purchased commercial site, rather than to build a road or a park, is not the ordinary use of the power, and it tells you how much the council wanted this particular project gone.

DC Blox answered in federal court on August 11th, suing Metro Nashville over the moratorium. The company's theory combined a due process claim, a Fifth Amendment takings claim, and an equal protection claim resting on the argument that a different Nashville data center developer, RadiusDC, kept getting its permits processed while DC Blox's applications sat frozen. Underneath all three was the same core assertion: that DC Blox's permits were already vested under Tennessee's vested-rights statute before the council ever voted, and that the new rules legally can't reach backward to stop a project that was already entitled to proceed under the old ones.

The ruling didn't decide what matters most

On October 7th, U.S. District Judge Eli Richardson dismissed every one of DC Blox's nine claims and denied its request for a preliminary injunction. Read quickly, that looks like a clean win for Nashville, and a lot of the coverage treated it that way. The order is narrower than that. Six of the nine claims were dismissed on their own separate legal grounds, including the equal protection claim: Richardson found the moratorium applies evenly to permit acceptance, processing, approval, and issuance for every applicant, RadiusDC included, so DC Blox hadn't shown it was singled out. But the other three claims, covering the due process and takings theories, were dismissed without prejudice specifically because DC Blox hadn't clearly identified which property interest it was actually claiming was violated. The company has 21 days from the ruling to refile with that clarified. Richardson was explicit that he wasn't ruling on the underlying dispute: not that Metro was right to freeze DC Blox's permits, and not that DC Blox lacks the legal right to build.

Here's the detail that's gotten the least attention in the coverage so far, and the one that matters most for anyone actually trying to figure out who wins this. Metro's own zoning administrator -- the city's in-house expert on exactly this question, not an outside advocate for either side -- has already concluded that DC Blox's Grassmere Park applications are protected under Tennessee's vested-rights statute, because they were filed under the zoning rules in effect at the time. In the zoning administrator's own words, "the proposed land uses being considered by the Council" are "not applicable to this project" for that reason. Johnston disagrees with her own city's staff finding, and that disagreement is now headed to Nashville's Board of Zoning Appeals, a separate and more technical forum than the federal lawsuit that's drawn all the headlines.

I think that's the real story here, more than the dismissal. A city can pass a moratorium, authorize eminent domain, and get a lawsuit dismissed, and still not have resolved the one question that actually governs whether a specific, already-filed permit survives: what the zoning rules said on the day it was filed, and whether the project met them. That's exactly the kind of fact the Kill Test is built to separate from the noise around it -- a signed purchase, a filed application, and a council vote are each real, but they sit on different rungs of the evidence ladder, and a win in one forum doesn't settle the rung that actually controls the outcome. Nashville's moratorium runs out December 1st. DC Blox's amended complaint, if it files one, is due by roughly the end of October. The zoning appeal has no public date yet. Whoever is actually deciding whether this data center gets built is not the federal judge who just ruled, and not the council that keeps voting. It's the Board of Zoning Appeals, on a straightforward factual question Metro's own staff has already answered one way.
