The Short Version
A $10 billion complex of computer buildings could come to Clinton, a small Iowa city on the Mississippi River. It may be the biggest project of its kind in the state. The company, QTS, has not formally applied yet.
About 100 people came to a city meeting to push for tougher rules. One of their main requests was changing one word: “may” to “must.”
That small edit matters. It helps decide whether requirements on things like water use and local roads are guaranteed from the start or left to later negotiation.
Iowa Public Radio reported that roughly 100 people attended a July 15, 2026 meeting of Clinton’s City Planning Commission, where the city attorney presented a draft of the city’s first data center ordinance. The rules are being written as QTS eyes Clinton for a $10 billion hyperscale campus, meaning a very large complex of data center buildings, that would rank among the largest data center investments in Iowa to date, if not the largest.
After about two hours of public comment, the commission put off a decision. It will reopen the public hearing at its August meeting and must finalize its recommendations before the ordinance goes to the city council for a vote. QTS has not yet submitted a formal proposal.
Executive Summary
Clinton is writing its data center rulebook before the project that prompted it has formally arrived. City attorney Patrick O’Connell described the draft as broader than the other eastern Iowa ordinances reviewed, with “more constraints, more regulations, more requirements in it than any of the other ordinances I reviewed.” Many residents at the hearing still asked for more.
The most consequential request was also the simplest: replace permissive wording such as “may require periodic water use reporting” and “may require a Road Use Agreement” with “must.” Most attendees wanted stricter terms written into the ordinance upfront rather than left to a development agreement, the project-specific contract a city negotiates with a developer later.
That matters beyond Clinton because it shows where a large project’s risk can sit before any construction plan exists. For a campus of this size, the choice between a mandatory rule and a discretionary one determines which conditions are settled in public code and which remain open for negotiation.
Why One Word Carries a $10 Billion Question
The dispute over “may” and “must” is really about when a condition gets decided and who decides it. Under “may,” the city council retains the option to impose a requirement, and the details can be settled later in a development agreement. Under “must,” the requirement applies automatically, and the negotiation starts from a higher floor. Theresa Andrews, who would be a direct neighbor of the data center, put the objection plainly: “there is far too much council discretion.”
Each approach has a cost. Discretion lets a city tailor conditions to a project it has not yet seen and gives both sides room to bargain, but neighbors must then trust a later process to deliver protections they cannot read today. Mandatory language gives residents and developers a clearer view of the baseline, but it can lock in requirements before the facts of a specific design are known. With $10 billion in potential investment under discussion, that wording could affect reporting obligations, road arrangements and the leverage each party brings to the table.
The people most directly affected are the immediate neighbors, the council members who would hold or give up that discretion, and QTS, whose eventual proposal would be measured against the final text. Any future applicant in Clinton would inherit the same rules. For developers and the AI and cloud customers who depend on new capacity, the lesson is practical: a zoning review means reading the verbs, not just confirming that a data center is an allowed use.
Writing the Rules Before the Proposal Arrives
The sequence gives Clinton unusual room to set terms. Because QTS has not filed a formal proposal, the ordinance is being debated as general policy rather than as a yes-or-no vote on a specific site plan. The city attorney also noted that the draft draws on measures adopted elsewhere in eastern Iowa, while acknowledging that “any one of those sections of the ordinance could be more strict than it is.”
Borrowing works in both directions. Each city’s ordinance can become a reference point for the next, so a comprehensive Clinton draft could influence later local debates if it is adopted. Clinton is not the only Iowa flashpoint: a potential data center has sparked a moratorium push in the northwest of the state, and Google has been reported to be eyeing Palo as a way around Linn County regulations. Those examples show local rules are a live siting consideration in Iowa, though they do not by themselves establish a statewide trend.
The immediate schedule effect looks modest. A few weeks of revisions is not a serious delay for a project that has yet to be formally proposed. The larger variable is what the August hearing and the later council vote leave in the final text, since that will determine how much is settled in code and how much remains for a development agreement.
Both Sides’ Claims Still Need a Project to Test Them
The draft opens with the city’s finding that “data centers may provide substantial economic development benefits, including tax base growth, construction activity, long-term employment, and significant private investment in real property and utility infrastructure.” Grow Clinton, an economic development nonprofit, is advocating for data centers in Clinton County to help build a sports complex and “ensure future growth.” These are benefits in outline. Their size depends on terms that have not yet been set out in a formal proposal or a development agreement.
Opponents’ claims face the same test. Resident Carol McGuire argued that “a data center is not good for Clinton and nothing in this ordinance changes that,” adding that it “puts the wealth of a few over the health of many.” Residents’ specific requests on well monitoring, noise and air quality identify legitimate things to measure, since data center impacts vary with design choices such as cooling method and backup power. How large those impacts would be in Clinton cannot be assessed without a project design.
That is an argument for the kind of reporting residents are requesting, and for evaluating benefit claims with equal care. Monitoring requirements would produce data that either side could cite later. A turnout of roughly 100 people is a clear sign of engaged opposition and concern, though not a measure of citywide opinion. Commissioner David Brown’s suggestion to pause, “This is so much to absorb,” drew applause and gave the commission time to work through the requests before its next hearing.
Background
Clinton is a small city on the Mississippi River in eastern Iowa, and it has not previously had an ordinance written specifically for data centers. A zoning ordinance is a local law that governs how land can be used and what conditions a development must meet. Clinton’s draft draws on measures adopted in other parts of eastern Iowa, and it must pass through the planning commission’s recommendations before going to the city council for a vote.
QTS is a data center company now eyeing Clinton for a $10 billion hyperscale campus. Hyperscale facilities are built to supply computing at very large scale, and their water use, noise, air emissions and road traffic are the kinds of local issues residents have raised in Clinton. Questions about those effects, weighed against promised tax base growth, construction activity and jobs, are at the center of the city’s debate.
