Is the New Data Center Proposal in Upper Macungie a Mistake?
Residents in Upper Macungie are voicing concerns about the new data center proposal—what does it mean for the community's future?
A frustrated resident shows up to not one but two zoning board meetings. That's not typical behavior. People who feel mildly inconvenienced don't do that. They show up when they believe something is genuinely at stake — when they think the decisions being made in a municipal hearing room will reshape the place they live.
That's exactly what's happening in Upper Macungie Township, Pennsylvania, where a proposed data center at the former Air Products site is drawing enough community pushback to warrant serious attention. Whether you're a developer, an investor, or simply someone tracking where large-scale infrastructure is landing, this situation is worth understanding — because it's a preview of conflicts playing out in communities across the country as data center demand accelerates.
What's Being Proposed — and Where
The former Air Products site in Upper Macungie is the kind of location that looks ideal on paper for data center development. Air Products and Chemicals, the Allentown-based industrial gas giant, left behind industrial-zoned land with existing utility infrastructure — the kind of brownfield asset that developers view as a ready-made opportunity.
Data center developers gravitate toward sites like this for a reason: prior industrial use typically means robust power access, favorable zoning classifications, and fewer greenfield permitting hurdles.
Upper Macungie itself sits in Lehigh County, in Pennsylvania's Lehigh Valley — a region that has become one of the mid-Atlantic's most active corridors for logistics, warehousing, and now digital infrastructure investment. Proximity to major fiber routes, reasonable land costs compared to Northern New Jersey, and access to PJM grid capacity make the area genuinely attractive for hyperscale and colocation operators.
The specific developer and technical specifications of this particular proposal aren't fully detailed in available public records at this stage, but the zoning board proceedings confirm the project is far enough along to require formal regulatory review — which means site plans, traffic studies, and utility load assessments are in play.
The Community Is Not Staying Quiet
Here's the thing about data center opposition that industry insiders sometimes miss: it's not usually NIMBYism in the classic sense. Residents aren't objecting to technology. They're objecting to consequences — specifically, consequences they feel weren't disclosed, weren't considered, or weren't weighed fairly against their interests.
The resident who wrote to express "deep frustration" after attending multiple zoning hearings represents a pattern. When community members invest time in bureaucratic processes they find confusing and exhausting, it signals that the perceived stakes are high enough to overcome the friction of civic participation.
What concerns typically drive this kind of engagement in data center cases? A few categories tend to dominate:
Power and utility load. A mid-sized data center can draw 20 to 100+ megawatts of power — enough to strain local distribution infrastructure and raise questions about rate impacts for neighboring residential customers. If PPL Electric Utilities, which serves this area, needs to upgrade substations or transmission lines to accommodate the load, those costs don't disappear. They get allocated somewhere.
Water consumption. Cooling-intensive data centers can consume millions of gallons of water annually. In communities already watching their watershed carefully, this is a legitimate infrastructure concern, not a talking point.
Traffic and noise. Diesel backup generators, cooling equipment, and 24/7 service vehicle access are realities of data center operations that don't show up in the architectural renderings presented at public meetings.
Zoning precedent. Perhaps most importantly, residents understand that what gets approved on one parcel sets expectations for adjacent parcels. Upper Macungie has been managing significant growth pressure for years. One approval can accelerate a pipeline.
The Economic Argument — More Complicated Than It Looks
Proponents of data center development reliably lead with job creation and tax base expansion. Both claims are technically true and strategically incomplete.
Data centers do generate significant tax revenue. A 100 MW hyperscale facility can represent hundreds of millions of dollars in assessed value — meaningful for a township's budget. Some states and municipalities have used data center tax incentives aggressively to attract investment, though Pennsylvania's incentive environment is more modest than Virginia's or Texas's.
The jobs argument requires more scrutiny. A large data center might employ 30 to 50 full-time workers once operational — a fraction of what an equivalent industrial facility might generate. Construction phases create temporary employment, but the long-term labor footprint of a highly automated facility is thin. For a community weighing infrastructure burden against economic return, that ratio matters.
There's also a displacement question. The Air Products site, depending on its condition and configuration, might be suited for uses that generate denser employment — advanced manufacturing, life sciences, or mixed-use commercial development. Once a site is committed to data center use, that optionality closes. Given that the Lehigh Valley is actively trying to diversify its economy beyond warehousing, locking a prime industrial parcel into a low-employment-density use deserves a harder look.
The Zoning Process Is Where This Gets Decided
Zoning board meetings are where abstractions become real. Site plans get examined. Traffic studies get challenged. Engineering assumptions get questioned by residents who've hired their own consultants.
In cases like Upper Macungie, the key zoning questions typically center on whether data center use is permitted by right under existing industrial zoning or whether it requires a special exception or variance. That distinction matters enormously — a use permitted by right gives the board limited grounds to deny, while a special exception process opens the door to conditions, modifications, and community benefit agreements.
If the project requires discretionary approval, residents and the township have meaningful leverage. That leverage expires the moment a gavel comes down.
Pennsylvania's Municipalities Planning Code governs the process, and it provides specific procedural rights to objectors — including the ability to present evidence, cross-examine applicants' experts, and appeal decisions to the Court of Common Pleas. Residents who are showing up repeatedly are, whether they know it or not, building a record. That record matters if the case moves to appeal.
Developers navigating this process in contested communities increasingly know that a pure legal victory at the zoning board can be a pyrrhic one. A project that clears approval over sustained community opposition faces ongoing friction — local political pressure, future permit challenges, utility coordination delays. The smart play, from a development standpoint, is to get ahead of concerns rather than run over them.
What Happens Next — and What It Means for Upper Macungie
The data center demand driving proposals like this one isn't speculative. AI workloads, cloud computing expansion, and the digitization of enterprise infrastructure have created genuine capacity shortages in established markets. That demand is real, and it's pushing development into second-tier markets — including the Lehigh Valley — faster than local regulatory frameworks were designed to handle.
That reality doesn't automatically validate any specific project. It does mean that Upper Macungie is unlikely to see this as the last such proposal. How the township handles this one — through process quality, transparency, and genuine engagement with community concerns — will shape how future proposals land.
For residents, the most effective path forward isn't reflexive opposition. It's informed engagement: understanding what conditions can be attached to an approval, what infrastructure commitments can be extracted from a developer, and what the actual alternatives for the site are. Opposition without an alternative is a delay, not a resolution.
For developers and investors tracking this market, Upper Macungie's situation is a case study in why community relations strategy needs to be front-loaded, not reactive. The projects that get built — and stay built — are the ones where the surrounding community wasn't surprised.
The resident who sat through two zoning hearings out of frustration isn't an obstacle. They're a signal. The question is whether anyone with decision-making authority is actually reading it.
