Is the New Data Center Development Worth the Risk?
Mercer County's proposed data center ordinance sparks debate—what's at stake for local developers and residents?
A single zoning ordinance is forcing Mercer County to confront a pressing question that communities across the country are grappling with: when a data center wants to move in, who actually benefits?
The answer is rarely simple. In Mercer County, it's already generating enough friction to bring the debate before the Planning and Zoning Commission — with residents like Petrey showing up to ensure their voices are heard before the concrete gets poured.
What the Ordinance Actually Proposes
The proposed data center development ordinance would open the door for large-scale data center construction in Mercer County — a move that would require the zoning commission to formally accommodate this category of infrastructure within its land use framework. That's not a trivial shift. Zoning codes are the DNA of how a community grows, and amending them to welcome data centers means making permanent decisions about land, power, water, and noise that will outlast any single administration.
The moment a county rewrites its zoning rules for data centers, it signals to the entire development market that it's open for business — and that signal is very hard to take back.
Key stakeholders are already positioned on both sides. Developers see a county with presumably available land and infrastructure capacity. Local residents — Petrey among them — see something different: the potential for an industrial-scale operation in a community that may not have signed up for it. The zoning commission sits in the middle, tasked with weighing competing interests while interpreting what "compatible land use" actually means when a 200,000-square-foot server facility is on the table.
The Economic Case — and Why It Deserves Scrutiny
Proponents of data center development ordinances almost always lead with jobs. It's an effective argument. Modern data centers do create construction employment — often hundreds of union jobs over an 18-to-24-month build cycle. The long-term operational footprint of a hyperscale facility can mean 50 to 200 permanent positions, depending on the level of automation.
The investment numbers are also real. A mid-sized data center development can represent $500 million to over $1 billion in capital investment, and the property tax contribution to local government can be substantial — in some jurisdictions, a single large facility has become the top taxpayer in the county.
But here's where the insider perspective matters: those headline numbers rarely survive contact with the fine print. Many data center operators negotiate aggressive tax abatements as a condition of siting. The "hundreds of jobs" figure often conflates temporary construction trades with permanent staff. The economic multiplier effects — the argument that a data center anchors broader commercial development — depend heavily on whether the facility serves local demand or is simply using cheap land and available grid capacity to serve markets elsewhere.
Mercer County developers and commissioners would be wise to demand specifics: What's the timeline for full property tax contribution? What's the local hiring commitment? What infrastructure upgrades does the county absorb?
What Residents Are Actually Worried About
Petrey's appearance before the Mercer County Planning and Zoning Commission represents something that doesn't always make it into the pro-development narrative — the people who live near these facilities and bear costs that never appear in an economic impact study.
Data centers are not quiet neighbors. A large facility runs diesel backup generators, high-capacity cooling systems, and HVAC equipment that operates continuously. Noise at the property line can be a genuine quality-of-life issue for adjacent residential areas. Then there's the water question. Cooling-intensive data centers can consume millions of gallons annually — a figure that lands very differently in a drought-prone region versus one with abundant water resources.
The environmental calculation for data centers is more complicated than it looks, and communities that don't ask hard questions upfront tend to regret it.
There are also subtler concerns that informed residents raise: What happens to property values in the immediate vicinity? What traffic patterns change during construction and operations? If the operator eventually exits or goes bankrupt, who inherits the infrastructure? These aren't hypothetical worries — they're documented outcomes from data center developments in other jurisdictions.
None of this means the project is wrong for Mercer County. It means the opposition showing up at the zoning commission is doing exactly what the process is designed for.
How Developers Should Actually Approach Zoning Approval
For developers pursuing data center approval in counties like Mercer, the instinct is often to minimize friction — get the ordinance passed, break ground, and deal with community relations later. That approach has a poor track record.
The more sophisticated play is to treat the zoning commission process as a genuine stakeholder engagement opportunity. That means presenting detailed operational data, not just economic projections. It means addressing noise, water, and visual impact specifically, with mitigation commitments that have enforcement teeth. Conditional use permits with binding performance standards are far better for long-term operating relationships than a clean approval that leaves neighbors feeling steamrolled.
Developers who shortcut community engagement tend to win the vote and lose the decade — through litigation, political reversals, and the reputational cost of being the company that "forced through" a project.
For the zoning commission itself, the ordinance language matters enormously. A well-drafted data center development ordinance will define minimum setbacks, noise decibel limits at property lines, water use reporting requirements, and decommissioning standards. A poorly drafted one leaves the county exposed. The difference between those two outcomes is usually the quality of technical expertise brought into the drafting process — and whether residents like Petrey are given enough information to engage substantively rather than just showing up to say no.
Where This Is Headed
Mercer County is not navigating this in isolation. Across the United States, rural and semi-rural counties with available land, relatively cheap power, and proximity to fiber infrastructure are fielding data center proposals at a pace that planning departments weren't built to handle. The AI compute buildout alone — which requires massive, power-dense facilities — has accelerated siting inquiries in counties that had never considered themselves data center markets.
That context cuts both ways for Mercer County. If the ordinance is crafted thoughtfully and the right development partner is selected, the county could capture genuine long-term value: tax base, infrastructure upgrades, and a foothold in the digital infrastructure economy. If it's rushed to accommodate a specific project on a specific timeline, the community absorbs the downside with little recourse.
The long-term community benefits of data center infrastructure are real — but they are not automatic. They require negotiated commitments, rigorous zoning standards, and an ongoing relationship between the operator and the county that doesn't end at the ribbon cutting.
Petrey stood up at that commission meeting because the decision being made would outlast the meeting itself by decades. That's the right instinct. The question now is whether the process gives it the attention it deserves — because the counties that get data center development right treat it as infrastructure policy, not just an economic development win.
