"Columbia County has approached this carefully and on its own terms," said Rick Evans, chairman of the Economic Development Authority of Columbia County, on August 26, describing the vote his board had just taken. What they approved was a memorandum of understanding worth at least $17 billion with Kinetic Infrastructure Solutions, an Alphabet subsidiary, for a data center campus at White Oak Technology Park, the stretch of land between Appling and Harlem that local news outlets have been covering under a Harlem dateline for months.
If you're looking at homes in Harlem right now, you've probably already heard some version of the headline: Google is coming, and property taxes might disappear. Both halves of that sentence are true in outline and misleading in detail. Here's what the county actually locked in on August 26, what still depends on a vote that hasn't happened yet, and what any of it means if you're deciding whether to buy in Harlem this year or wait.
What Got Approved, and What Didn't
The August 26 vote by the Economic Development Authority of Columbia County covers financing and zoning, not tax relief. The $17 billion commitment is structured as a bond-for-title arrangement, a financing method long used in Georgia where the private company, not the county, carries the debt. The bonds are non-recourse to the county and the authority, meaning no resident's taxes repay them and the county's credit isn't on the hook if the project underperforms.
That's the part that's settled. The property tax relief that's driving most of the local conversation is a separate, still-pending question.
County Manager Scott Johnson laid out the mechanism in a July 28 briefing: the path runs through House Bill 439, legislation the county itself wrote and which has already passed both chambers of the Georgia General Assembly. The bill lets local governments set aside data center revenue for homestead tax credits, but only if voters approve it. That vote happens in November 2026. If it passes, Johnson said residents could see credits on their bills as early as 2027. Full elimination of the homestead property tax, the number that's been circulating in national coverage, isn't projected before 2028 at the earliest, and Johnson noted a separate state constitutional amendment is still required to lift the cap on how much relief the fund can actually deliver.
Two votes, two different bodies, two different timelines, before a homeowner sees a dollar of relief locked into law.
The Number That Doesn't Quite Match the Headline
Property taxes currently fund about 40 percent of Columbia County's total budget, according to County Commission Chairman Doug Duncan, who has said the county's goal in courting data centers is to eliminate its share of homestead property taxes altogether. The new agreement is projected to deliver $40 million a year to the county for seven years. Homestead property taxes across the county currently bring in roughly $25 million annually.
On paper, $40 million a year covers $25 million a year with room to spare. In practice, that $40 million has other claims on it before it reaches a homeowner's bill. Some of it flows to the Development Authority rather than directly into the tax relief fund. Some of it is earmarked for infrastructure and services tied to the project itself. The county has said additional details on a comprehensive relief plan are still coming, which is a polite way of saying the exact homeowner-facing number hasn't been finalized even as the headline writes itself as "taxes eliminated."
Here's a plain look at what's actually locked in versus what's still a promise:
| Locked in as of August 26, 2026 | Still pending |
|---|---|
| $17 billion investment commitment from Kinetic Infrastructure Solutions | November 2026 referendum authorizing the county to use data center revenue for homestead relief |
| Bonds structured as non-recourse; county credit not pledged | State constitutional amendment needed to lift the cap on the relief fund |
| Data Center zoning overlay with buffers, noise limits, and decommissioning requirements | First tax credits, if approved, expected no earlier than 2027 |
| $40 million a year committed to the county for seven years | Full elimination of homestead property tax, not projected before 2028 |
If you're budgeting a home purchase in Harlem around the assumption that your tax bill is about to shrink, the honest answer is: maybe, starting in 2027 at the earliest, and only if two separate votes go the county's way between now and then.
The Buffer Zone Only Matters If You're Close to It
The zoning standards attached to the White Oak site are real and already in place, which is more than can be said for the tax relief timeline. Authority officials describe the Data Center zoning district as among the strictest in Georgia. It requires:
- A 500-foot buffer between the facility and any residential parcel
- A 65-decibel noise limit measured at the property line
- Closed-loop cooling, which means no reliance on private wells
- Full-cutoff lighting fixtures to limit glare and light spill
- A decommissioning plan required for the end of the facility's useful life
Those standards matter most if you're looking at a parcel near Pumpkin Center or another home close to the White Oak footprint itself. A house a few miles into Harlem proper, away from the immediate site, isn't going to feel the noise or lighting rules one way or another. The tax question, on the other hand, applies countywide regardless of how close you live to the actual buildings.
Johnson also addressed a question a lot of buyers ask without saying out loud, which is whether this is the first of many sites. As of his late-July briefing, he said the county does not need additional data centers to reach its tax relief goals, and that there were no active rezoning requests in the pipeline at that time, though landowners and developers have reached out. That's not a guarantee about what happens next year, but it's a useful data point if you're weighing how much more growth to expect in the immediate area before you commit to a parcel.
What This Means If You're House Hunting in Harlem Right Now
The mistake would be treating this deal as a reason to either rush in or wait it out. It's neither yet. The tax relief isn't law. It's a proposal with a real chance of passing, backed by legislation the county already wrote and a revenue stream that's already been approved on the corporate side. But it depends on a November referendum and a state constitutional change, and even in the best case the money shows up gradually starting in 2027, not all at once.
What you can act on now is the physical geography. If a listing sits close to the White Oak footprint, ask specifically how close and what that 500-foot buffer looks like on the actual parcel lines, not just the marketing map. If a listing is further into Harlem's established neighborhoods, the zoning overlay is mostly irrelevant to your day-to-day, and the tax question is the same one every Harlem buyer is watching regardless of address.
Either way, this is exactly the kind of local detail worth walking through with someone who's tracking the county's actual filings and public statements rather than the national headline version of the story.
A Few Questions Worth Asking
Will my property tax bill go down this year because of this deal? No. The relief mechanism requires a November 2026 referendum and a state constitutional amendment, neither of which has happened. Officials have said credits could begin as early as 2027 if voters approve.
Does the zoning overlay affect homes anywhere in Harlem, or just near the site? Just near the site. The 500-foot buffer, noise ceiling, and lighting standards apply to the immediate area around White Oak Technology Park. Homes elsewhere in Harlem aren't governed by this overlay.
What exactly is White Oak Technology Park? It's the site between Appling and Harlem where the data center campus is planned, adjacent to the existing White Oak Business Park.
What happens if voters reject the November referendum? The county has said additional details on a full relief plan are still forthcoming. A rejected referendum would mean the current path to homestead tax relief through this specific revenue stream would need to be revisited, though the underlying investment and zoning agreement would still stand on its own terms.
If you're weighing a purchase in Harlem and want to talk through what a specific address means for both the zoning question and the tax question, that's a conversation worth having before you write an offer, not after. Tara McNaylor can walk you through both.
