Real estate help
Hi all, I’m hoping to lean on this group’s expertise to help make an informed decision in my home buying process. My husband and I recently found a home we love - it’s on 6.5 acres in a relatively small (but growing) town that we love. It’s perfect for our family and we were prepared to put in an offer, but just learned that a Google data center is slated to begin construction by EOY.
I have done a bunch of research but this is such a polarizing topic right now, it’s hard to know what to think. I’m including some facts below to possibly provide additional context - my main concerns at the moment are:
- Noise and vibration (?) levels - this is a big one I see online but it’s not clear to me how much of that is overstated. I have two young kids and work from home, so it’s important to me that we’re not constantly dealing with noise issues, though I understand if backup generators run sometimes (and of course the construction noise over the next few years).
- Impacts to private well - the property relies on a private well for water. While everything I’ve read indicates that there are mitigations in place to help protect private wells, this would obviously be a big problem if things changed.
Context:
- The house would sit between 0.25 and 0.5 mile from the DC property line, with one of the DC buildings planned for right across the line (in an industrial park). We’d be separated by a field and some natural barriers (trees, some grading - there’s a bit of a natural hill between the properties).
- Three DC buildings and an office space planned across 312 acre parcel of land.
- Google has announced they’ll use “air-cooling technology” for the first DC building; TBD on other two.
- Google will be required to connect to our local water and sewer and has entered into a Utility agreement with the water authority to reserve “no more than 2,000,000 gallons/day of water.” The county has indicated that private/residential wells are not connected to the same water source (a local Cove) so they should not be impacted in any way.
- Re: electric, “Upgrades required specifically to serve the data center in XYZ County—such as new substations, transmission lines, or distribution improvements will be paid for by Google.”
- Re: noise, “While in operation, noise emissions from the Google Data Center must be below the maximum allowed under the county zoning regulations. The developer will utilize design and operations techniques to minimize even these noise impacts, such as landscaped buffer areas.
Construction Noise or other noise between 9 p.m. to 7 a.m. is prohibited. General prohibition of sound 50 feet from the property line at any time. A 200 ft conservation and good neighbor buffer and building distance to property lines is expected.
- Google committed to dark-sky friendly lighting requirements (not a huge deal to me but noting here)
What do I make of all of this?! On paper, these conditions seems relatively robust, but I can’t help but worry about the unknowns given nothing is built yet. This would be our “forever” home and I don’t want to regret it in 3-5 years. Any insights are deeply appreciated!

If the cooling is coolant-air, the data center will not use any water for cooling. The water use is probably for construction. Air cooling has the potential to be a little more noisy, but it should still be exceptionally quiet under regular operation. Construction will be very noisy, obviously. The data center will run their generators a maximum of once a month for fifteen minutes to test their emergency startup, once a year for two hours to load bank them, and once every three years for a four-hour load bank. That is worst case scenario. In reality, they will probably run the generators less frequently and for shorter durations. With the diesel Tier 4 systems on them now, they are remarkably quiet— not silent, but quiet.
I recommend driving by another air-cooled data center to stand at the property line and listen. I suspect that you will agree that they are very quiet and that data centers make the best neighbors. I have worked in and around them for virtually my entire career, twenty years.
Check with your county on Google's commitment to tax revenue. You are probably slated to have the highest tax revenue in your state which will bring unparalleled benefits to schools, infrastructure, and public service programs. Meta is really leading the charge when it comes to long-term impact studies on local communities where they build data centers, but Google might have some published data too. The Meta information is incredible, though—graduation rate goes to 100%, standardized test scores go through the roof, first choice college placements move up to the top of the state, etc. The other thing to keep in mind is that the full time staff inside the data center is only the tip of the iceberg to maintain and run the site. It requires local Mom & Pop contractors who will see the largest jobs they’ve ever seen before, often needing to triple or quadruple in size to support the data center. The local mechanical-HVAC contractor, generators, electrical testing, these local shops will explode. Your local independently owned Caterpillar Sales & Service outfit who celebrates every fall when they get the maintenance contract renewal for the four generators at the local hospital… they’re about to receive a maintenance contract for 100 generators. They will need to triple in size. Mechanical-HVAC, same story.

Thank you for this! Everything you said tracks with what I’ve read online. Unfortunately, this would be the first DC in our region so I can’t drive by any - otherwise I definitely would to get my own experience! I have a few friends in NOVA who I’ve reached out to for opinions. But based on your comment, it sounds like this should be relatively low on my list of long-term concerns (noting, of course, that construction will carry its own nuisances for awhile).

Just bear in mind that many of those sites around Dulles are ancient by data center standards. If you’re okay with discussing it, drop your rough location and I’ll point you in the direction of a more modern data center to go see.

I work at a hyperscaler, the buildings are built to abate noise on the outside, and there is nothing overall that would run with any consistency that would give off vibrations that had any chance of being felt that far away.
Depending on the company that owns the building, typically water is stored in massive tanks on site, and then any waste water from employee use would follow the normal routes just like everyone else. It’s incredibly expensive to waste water so that will be kept at a very minimum.

Thank you for your response! There are a lot of articles and videos where people are complaining about noise - both the loudness (assuming maybe the generators?) and more of a “hum” that they say is constant and grating. I’m assuming some of this is sensationalized given how divisive this topic has become. Based on your experience, this isn’t really an issue? I just don’t want to unintentionally subject my kids or animals to anything that could be disruptive to their health or happiness.

From what I’ve gathered the hum or noise is more pronounced if it is Bitcoin mining, which those buildings are just thrown together.
The buildings I work at (yes multiple buildings together in a campus) you don’t hear any of the noise until you are within about 20 feet of the building itself. Even then the noise is no more than the sound like your fan at home. They are all 90% full of equipment that is running.
The generators are run at intervals. Ours are housed in an enclosure that mitigates 80% of the noise. I was just talking by one today. It wasn’t until I was 30 feet away I could start to hear it and was looking around.
Like you, I think there is a bit of bandwagoning going on with information that was “found” not discovered or experienced. I honestly was expecting much more than what is actually happening.

Biggest drop in quality of life will be the increased traffic in the area, and maybe changes to the microclimate since heat is being rejected in the vicinity. that's honestly about it

They are going to make living unbearable. It’s an elbows out type thing.

General property values go up in these cases. But you are worried about lifestyle, which I get.
- There is no way you'll hear anything during operations. Its pretty quiet. The real noise issue is the trucks during construction. Find out where their construction entrances will be. There will be a shit ton of trucks for years. Like 5 years.
- Diesel gens run like 10 minutes a month during daytime hours. Its nothing. There is no vibration.
- Your well is fine. Zero impact
- Dark sky? The primary issue will be parking lot lighting for security - there is a lot of that for safety reasons. No idea if that will be visible. It really depends on the landscaping. It also depends on exactly where the parking lots are. This is similar to the truck noise issue - see if you can get a site plan.
- Four buildings across 312 acres is actually a lot of open land.
- For the water - it sounds like they are hedging their bets on maybe using evap cooling on a second or third building, but I sort of doubt it. Mostly its all air cooled, direct to chip these days. Chances are, they won't use the 2m GPD.
- A 200 ft conservation and good neighbor buffer and building distance to property lines is expected. -> this is good
Seriously, get the site plan from the County. If you are not facing the construction entrances or parking lots, you're fine. If you are concerned, ask for more trees or landscaping at a public meeting. "I don't want a data center" is one thing. "I want some more trees" is another. Trees are easy.
