Mifflin County Data Center Appeal Highlights Local Zoning Challenges

Executive Summary

A data center developer has filed an appeal after Mifflin County officials rejected their application, exposing a friction point that is becoming increasingly common across rural Pennsylvania: local zoning frameworks that were never designed with large-scale digital infrastructure in mind. Leadership instability in Granville Township adds a second layer of uncertainty, creating unpredictable timelines for developers who need regulatory clarity to move capital. Developers who do their zoning homework before submitting applications will move faster than those who treat permitting as a formality. Those who don't will find themselves in the same appeals queue.

What Happened

A data center developer filed an appeal following the rejection of their application by Mifflin County officials. The rejection appears tied to local zoning regulations that do not straightforwardly accommodate data center uses — a recurring problem in municipalities where land use codes predate the AI infrastructure build-out cycle.

The situation in Granville Township has been further complicated by leadership changes. Township Manager Mary Herto did not make herself available for comment. Governance gaps created by resignations or leadership transitions typically slow administrative decision-making and can leave permit applicants without a clear point of contact or a predictable review timeline.

The specifics of the application — including the proposed facility size, power requirements, and exact parcel details — were not disclosed in the available source material. What is clear is that the developer has chosen to contest the rejection rather than withdraw, signaling confidence in their legal or procedural position.

Why This Matters

This is not an isolated permit dispute. It is a signal that secondary markets in Pennsylvania — counties with available land, lower costs, and proximity to fiber corridors — are beginning to attract data center interest, but their regulatory infrastructure has not kept pace with their economic appeal. That gap creates friction, and friction costs developers time and money.

Granville Township's leadership instability matters beyond this single application. When boards are gridlocked or short-staffed, routine items stall. For a developer sitting on a signed land option with a ticking clock, a township that cannot convene a quorum or staff a zoning hearing is effectively a blocked pipeline.

As Tier 1 markets like Northern Virginia, Phoenix, and Chicago approach saturation on power and land, developer interest in Tier 2 and Tier 3 markets is accelerating. That makes the regulatory readiness of counties like Mifflin increasingly consequential — not just for one project, but for the wave of site selection decisions that follow.

The appeal itself will generate a public record. How Mifflin County handles it will be watched by other developers evaluating Pennsylvania sites.

Power & Interconnection Impact

Zoning rejection at the local level is often the first domino, but it has direct consequences for interconnection timelines. A project that cannot secure land use approval cannot advance its interconnection application in any meaningful way — utilities and ISOs require site control or, at minimum, a credible path to site control before dedicating engineering resources to a queue position.

If the proposed facility carries the power load typical of a mid-scale AI or colocation data center — anywhere from 20 MW to 100 MW — delays measured in months at the zoning stage translate to equivalent delays in substation design, transformer procurement, and transmission studies. In the current environment, where transformer lead times run 18 to 24 months or longer, a zoning-driven six-month slip can compress an already tight schedule into an infeasible one.

Developers facing similar situations should treat interconnection pre-application discussions with the serving utility as parallel-track work, not sequential. Getting informal feasibility feedback before zoning is resolved can at least keep the power side of the project from falling further behind.

Land, Zoning & Permitting Impact

The core issue here is a zoning code mismatch. Most rural and exurban Pennsylvania townships operate under zoning ordinances written for agricultural, residential, or light industrial uses. Data centers — with their utility-scale power draws, restricted access, minimal employment footprint, and 24/7 operational profiles — often do not fit cleanly into any existing use category, triggering conditional use hearings, variances, or outright rejection.

Developers entering markets like Mifflin County should conduct a zoning code audit before signing land options, not after. Identifying whether data centers are a permitted use, a conditional use, or a prohibited use in the target zoning district is a due diligence step that takes days and can prevent multi-month appeals.

Leadership turnover in Granville Township introduces an additional variable. New supervisors may hold different views on economic development, tax ratables, and the community trade-offs that large infrastructure projects represent. A project that was marginal under one board can become viable under the next — or vice versa.

Developers should be building relationships with township officials, planning commissions, and county economic development offices well before filing applications. Showing up at a public hearing as a stranger is a disadvantage that is entirely avoidable.

Investment Takeaway

Regulatory risk is underpriced in secondary markets. Investors evaluating Pennsylvania data center sites should require a zoning opinion letter and a conditional use analysis as part of pre-LOI diligence, not post-signing.
Leadership instability is a project-level risk factor. A township mid-transition between administrators or supervisors may be unable to process applications on normal timelines. Model the delay scenario explicitly.
Appeals processes vary by jurisdiction. In Pennsylvania, zoning appeals typically run through the Zoning Hearing Board and can then proceed to the Court of Common Pleas. A contested appeal adds six to eighteen months to a project timeline in most Pennsylvania jurisdictions.
The underlying demand signal is valid. The fact that a developer found Mifflin County worth pursuing at all reflects the tightening of Tier 1 markets. The site economics may still work — the regulatory path just got longer.
Projects with pre-cleared zoning carry a premium. In this environment, entitled land in Pennsylvania — even outside primary markets — commands a meaningful price advantage over raw land with uncertain use approvals.

InfraSale Market Angle

For developers actively scouting Pennsylvania sites, the Mifflin County appeal is a useful calibration. It confirms that landowner and developer interest in central Pennsylvania is real, but that local zoning infrastructure in many townships has not been updated to reflect the current data center demand cycle.

The practical implication: developers who invest in pre-application stakeholder engagement — attending township meetings, briefing economic development offices, commissioning traffic and utility impact studies before being asked — will move through approval processes faster than those who rely on the application itself to make the case.

Developers sourcing sites in secondary Pennsylvania markets should use this moment to differentiate. Being the developer who shows up informed, with community benefit framing and a clean zoning analysis, is a competitive advantage when multiple projects are competing for limited local political bandwidth.

FAQ

What are the current zoning challenges in Mifflin County?

Mifflin County's zoning framework, like many rural Pennsylvania counties, was built around agricultural, residential, and light industrial uses. Data centers often fall outside clearly defined use categories, requiring conditional use approvals or variances that trigger public hearings, neighbor objections, and extended review timelines. The appeal filed in this case suggests the existing code did not provide a clear path to approval for the proposed facility.

How do governance changes impact data center approvals?

Local boards and township managers play a direct role in scheduling hearings, interpreting zoning ordinances, and setting the tone for how economic development proposals are received. When leadership changes through resignations or elections, institutional knowledge walks out with departing officials, and incoming supervisors may hold different priorities. For developers, this creates timeline uncertainty that is difficult to model and harder to hedge.

What should developers consider before applying for permits?

Developers should conduct a zoning code audit of the target jurisdiction before executing a land option, confirming whether data centers are a permitted use, conditional use, or require a text amendment. They should also map the local approval process — who sits on the zoning hearing board, what the public notice requirements are, and what the realistic timeline looks like from application to decision. Engaging township staff and economic development offices before filing reduces the risk of a cold rejection.

Can a rejected application be successfully appealed in Pennsylvania?

In Pennsylvania, applicants can appeal zoning rejections to the local Zoning Hearing Board, and adverse ZHB decisions can be appealed to the Court of Common Pleas. Success depends on whether the original decision was legally supported by the zoning ordinance or represented an abuse of discretion. Appeals can take six to eighteen months or more depending on jurisdictional backlog.

Why are data center developers targeting secondary markets like Mifflin County?

Primary data center markets — Northern Virginia, Phoenix, Chicago, Dallas — are under significant stress on available power, land, and interconnection capacity. Developers are expanding their search to secondary and tertiary markets that offer land availability, lower costs, and proximity to fiber and regional transmission infrastructure. Mifflin County's appeal to a developer reflects that broader market rotation, even if the local regulatory path proved more complicated than anticipated.
