Carroll Twp.'s Bold Move on Data Center Regulations
Carroll Twp. is reshaping data center regulations. Discover how these changes could impact your next infrastructure project!
Most townships don't make national infrastructure news, but Carroll Township just might.
On March 10, Carroll Township supervisors advanced a proposed zoning amendment specifically designed to define and regulate data center development within its boundaries. That's a short sentence describing a decision with long legs. When local governments start writing new language around data centers — not just permitting them under existing industrial or commercial codes, but *defining* them as a distinct use category — it signals something larger is happening in the relationship between municipalities and the hyperscale economy.
This is how regulatory frameworks get built: one township at a time.
Understanding Carroll Twp.'s Zoning Amendment
The core of what Carroll Township supervisors advanced is definitional. Before you can regulate something, you have to define it — and until recently, most municipal zoning codes had no specific language for data centers at all. They were shoehorned into industrial zones, permitted by variance, or quietly approved under ambiguous commercial classifications. That worked when data centers were rare and relatively small. It doesn't work when a single facility can consume 100+ megawatts of power, require industrial-scale cooling water, and generate significant traffic from maintenance crews and fuel delivery trucks.
By creating a distinct zoning category for data center development, Carroll Township is doing something most municipalities haven't: treating data centers as the unique infrastructure class they actually are.
The amendment's advancement by supervisors on March 10 means it cleared an early but meaningful hurdle. Township supervisors don't typically fast-track amendments they're not serious about. The next steps — public comment periods, potential revisions, and final adoption — will determine exactly what the final framework looks like. But the direction is set.
What likely drives this isn't hostility toward data centers. It's the opposite: the recognition that data center investment is coming whether zoning codes are ready or not, and it's better to shape that growth than scramble to respond to it.
Implications for Data Center Development
For developers and operators eyeing Carroll Township, the amendment is a two-sided coin.
On one side: clarity. Defined zoning categories mean developers know upfront what's permissible, what requires special exception, and what's off the table. That reduces permitting uncertainty — one of the most expensive friction points in large infrastructure projects. A developer who knows exactly what Carroll Twp.'s data center zoning requires can design to those standards from the first site plan, rather than navigating a maze of interpretive decisions by planning staff and zoning boards.
On the other side: constraints. New zoning language typically includes setback requirements, noise ordinances, height limits, utility capacity standards, and sometimes environmental review thresholds. Data centers that might have slipped through under a broad industrial designation may now face more rigorous review — particularly around power infrastructure, stormwater management, and visual impact. That's not necessarily bad for the industry long-term, but it adds complexity to projects that were already capital-intensive.
The insider perspective here matters: developers who've operated in jurisdictions with mature data center zoning frameworks — Northern Virginia's Prince William County comes to mind — consistently report that clear rules, even demanding ones, accelerate project timelines compared to regulatory ambiguity. The worst environment for infrastructure investment isn't strict regulation. It's unpredictability.
What Developers Should Watch
The specific language of the amendment will determine everything. Key provisions to scrutinize once the final text is available:
- Use definitions: Does the ordinance distinguish between hyperscale campuses, colocation facilities, and edge deployments? A 500MW campus and a 2MW edge node have almost nothing in common operationally, but many zoning frameworks treat them identically.
- Power and utility thresholds: Some municipalities are beginning to set megawatt caps or require utility impact studies above certain load thresholds. If Carroll Township goes this direction, it will significantly influence which projects are viable.
- Conditional use requirements: What triggers a conditional use permit versus by-right development? This is where negotiations get real.
Investment Opportunities in Carroll Twp.
The fact that Carroll Township supervisors felt compelled to advance this amendment at all tells you something about the investment pressure they're responding to. Municipalities don't draft zoning language for hypothetical futures. They draft it when developers are calling.
Pennsylvania has been on the radar for data center expansion for several reasons. Power availability — particularly access to PJM grid interconnection — matters enormously in site selection. So does proximity to Tier 1 markets like Philadelphia and Pittsburgh without being priced into those markets. Land costs in townships like Carroll are a fraction of what developers pay in established data center corridors.
For infrastructure investors, the window between "municipality drafting regulations" and "regulations fully adopted and market saturated" is often the best entry point.
State-level incentives add another layer. Pennsylvania's data center tax exemption — which covers sales tax on servers, power, and cooling equipment for qualifying facilities — is among the more competitive in the Mid-Atlantic. Developers who can structure projects to capture both the state-level incentive environment and a clear local zoning framework have a meaningful cost advantage over comparable projects in less prepared jurisdictions.
The Carroll Twp. data center zoning amendment, whatever its final form, signals that the township is getting its regulatory infrastructure ready. That's not a minor administrative footnote — it's a market signal.
Future-Proofing Your Data Center Projects
Here's the non-obvious point that often gets missed in coverage of local zoning actions: regulations adopted today will govern projects that won't be fully operational until 2027 or 2028. The zoning language being written now needs to accommodate technology that doesn't fully exist yet.
Liquid cooling is the clearest example. Air-cooled data centers have been the standard for decades. But as GPU-dense AI workloads push rack densities from 10-20kW per rack toward 100kW and beyond, liquid cooling — direct-to-chip, immersion, rear-door heat exchangers — becomes mandatory. Zoning frameworks written around air-cooled assumptions may inadvertently prohibit or complicate the cooling infrastructure next-generation facilities require.
Developers engaging with Carroll Township's amendment process right now have a genuine opportunity to shape the regulatory framework rather than simply comply with it.
That means showing up to public comment periods, not just monitoring them. It means submitting technical input on use definitions and utility standards. Municipalities genuinely benefit from developer expertise in this process — most township planning commissions don't have staff who deeply understand data center operations. The developers who engage constructively tend to get regulatory environments that work for their projects. The ones who show up after adoption and complain about the rules rarely get much sympathy.
For compliance planning, the practical checklist is straightforward: retain local land use counsel familiar with Pennsylvania municipal law before site acquisition, not after. Commission preliminary utility impact studies that can be presented proactively to township officials. And build relationships with the supervisors and planning commission members who are actually writing these rules — in townships like Carroll, those are real people who answer their phones.
The Precedent Question
Carroll Township is one municipality. Its zoning amendment, on its own, doesn't reshape the national data center market.
But watch the pattern. As data center demand accelerates — driven by AI infrastructure buildout, cloud expansion, and enterprise digital transformation — the pressure on secondary and tertiary markets intensifies. Land-constrained primary markets in Northern Virginia, Phoenix, and Silicon Valley are pushing developers outward. That means municipalities across Pennsylvania, Ohio, Indiana, and the broader PJM footprint are going to face the same questions Carroll Township is addressing now.
The townships that have clear, well-crafted zoning frameworks in place will attract investment. The ones that don't will either lose deals to better-prepared neighbors or find themselves approving facilities under frameworks that weren't designed for them — and dealing with the community conflicts that result.
Carroll Township's supervisors may not be thinking of themselves as setting national precedent. But that's often how precedent gets set — by local officials making practical decisions in front of them, one zoning amendment at a time.
If you're tracking Carroll Twp. data center zoning developments — as a developer, investor, or neighboring municipality — the March 10 advancement is the moment to start paying close attention. The final regulatory text will define the real opportunity.
