Is Rezoning Agricultural Land for Data Centers Smart?

The fields are quiet, but the zoning map is not.

Across rural America, agricultural parcels that once grew corn, soybeans, or sat fallow are increasingly finding their way onto the shortlists of data center developers. The pitch to local officials usually sounds something like this: minimal traffic, massive tax revenue, hundreds of construction jobs. What's not to like?

Quite a bit, actually — if you're not asking the right questions first.

Rezoning agricultural land for data centers is one of the more consequential land use decisions a county can make. Done well, it can transform a struggling rural economy. Done carelessly, it locks communities into trade-offs they didn't fully understand when they signed the paperwork. The decision deserves more scrutiny than it typically gets.

Why Data Centers Are Coming for Agricultural Land

The numbers driving this trend are not subtle. Global data creation is projected to hit 120 zettabytes by 2023, and AI workloads are accelerating that curve sharply upward. Every large language model training run, every streaming video, every connected device pushing telemetry to the cloud — all of it needs a physical home. That home is a data center, and data centers need land.

A lot of it. A hyperscale facility might consume 100 to 500 acres, require 100+ megawatts of power at full buildout, and draw millions of gallons of water daily for cooling. Urban and suburban land can't accommodate that footprint at a price that makes development economics work. Agricultural land can.

The math is brutally simple: rural agricultural land might trade at $5,000 to $15,000 per acre, while comparable industrial-zoned land near power infrastructure can run five to ten times that.

Rural parcels also offer something developers prize even more than cheap land — proximity to transmission infrastructure without the political complexity of dense neighborhoods. A 500-acre farm near a 345kV transmission corridor is, from a data center developer's perspective, a nearly perfect blank canvas. That explains why you're seeing serious conversations about rezoning agricultural land for data centers in places like central Virginia, rural Iowa, central Texas, and the Carolinas.

What Rezoning Actually Involves — and Why It's Harder Than It Looks

The rezoning process sounds procedural. In practice, it's political, technical, and sometimes contentious.

The basic pathway runs through the local planning commission: a developer submits a rezoning application, staff reviews it against the comprehensive plan, the planning commission holds public hearings and makes a recommendation, and the county board of supervisors or commissioners makes the final call. On paper, that process might take six to eighteen months. In contested cases, it stretches longer.

The substantive challenges are harder to navigate than the procedural ones. Comprehensive plans — the long-range land use documents that most counties maintain — often explicitly protect prime agricultural soils or designate rural land for agricultural preservation. A rezoning request that runs counter to those designations forces local officials to make a values judgment, not just a technical one.

Neighbors raise legitimate concerns about water consumption, visual impact, noise from cooling systems, and the loss of farmland that, once converted, almost never reverts.

Traffic is usually a non-issue — data centers don't generate much of it after construction — but the infrastructure demands tell a different story. A 200-megawatt facility pulling power from the local grid can stress substations and require transmission upgrades that utilities and developers negotiate behind closed doors, sometimes with ratepayers absorbing costs they never voted on.

Experienced infrastructure planners know to look past the rezoning itself to the interconnection queue. If a site doesn't have a credible path to grid interconnection within a reasonable timeline, the rezoning approval is essentially worthless. Some developers learn this lesson after the fact.

The Factors That Actually Determine Whether a Rezoning Succeeds

Local regulations are the obvious variable. But the less obvious factors often matter more.

Economic impact assessments have become central to the rezoning conversation — and they deserve skepticism on both sides. Developers commission studies that emphasize property tax revenue (often tens of millions of dollars annually at full buildout), construction employment, and multiplier effects. Critics point out that permanent employment at data centers is thin: a 100MW facility might run with 30 to 50 full-time employees. That's not nothing, but it's not the job-creation story that traditional industrial development delivers.

The honest version of the economic case for data center development is less about jobs and more about the fiscal math. A data center paying $20 million a year in property taxes to a county with a $40 million annual budget changes what's possible for local schools, roads, and public services. For the right community, that tradeoff — farmland converted, few direct jobs, transformative tax revenue — is worth making.

Water availability is emerging as an equally critical constraint. Cooling a large data center can consume 3 to 5 million gallons of water per day, a figure that puts facilities in direct competition with agricultural users who depend on the same aquifers. Counties in water-stressed regions are starting to treat water access as a threshold issue before they'll entertain rezoning discussions.

Power infrastructure, water rights, and the county's existing comprehensive plan are the three variables that most reliably predict whether a rezoning application succeeds or fails. Get two out of three wrong, and the project stalls.

What the Track Record Shows

Prince William County, Virginia, processed one of the more closely watched data center rezoning battles in recent memory. The county designated a "rural crescent" for agricultural preservation decades ago, then watched as data center demand pressure pushed developers to its edges. The resulting debate — over traffic, water, and the rural character of the county — played out over years and produced a more nuanced zoning framework that tried to direct data center development toward already-disturbed land rather than prime farmland.

The lesson from Virginia isn't that rezoning is always wrong. It's that the absence of a proactive land use strategy forces communities into reactive, parcel-by-parcel fights that satisfy no one. Counties that have done this well — Loudoun County, Virginia, is the canonical example, now home to the largest concentration of data centers on earth — built their frameworks early, designated appropriate zones, invested in infrastructure, and captured enormous fiscal benefits as a result.

The counties that struggle are the ones getting their first serious data center proposal with no existing policy framework to evaluate it against. They're making permanent land use decisions under time pressure, often with developers who are far more sophisticated negotiators than local planning staff.

What Comes Next

Infrastructure planning for data centers is evolving fast, and two trends will reshape the rezoning calculus over the next decade.

Sustainability pressure is already changing where developers look and what they'll build. Hyperscalers including Microsoft, Google, and Amazon have made net-zero commitments that force real decisions about water use, carbon intensity of local grids, and land impact. Developers willing to invest in air cooling, on-site renewable generation, or brownfield redevelopment are finding they face shorter regulatory timelines and less community opposition — because they've addressed the most common objections before the hearing room fills up.

The second trend is the geographic diversification of data center development itself. The industry spent twenty years concentrating capacity in a handful of markets — Northern Virginia, Silicon Valley, Phoenix, Dallas. That concentration is now a liability: power constraints, water stress, and land costs are pushing development into secondary markets. That means more rezoning applications in places that have never seen one before, from county planning commissions that have never evaluated one.

Communities that develop clear, proactive frameworks for data center land use — defining where development is appropriate, what infrastructure commitments are required, and what fiscal benefits must flow to the public — are positioned to capture real economic gains without sacrificing agricultural land that took generations to cultivate.

The smart move for any county sitting on this question right now isn't to approve or deny the next application that comes in. It's to build the policy infrastructure to evaluate all the ones that follow. Because if the demand trajectory holds — and there's no credible scenario where it doesn't — there will be more applications. The question is whether your community is ready to make those decisions on its own terms.
