Drive down I-84 along the Columbia River and you'll see it. The landscape in Gilliam County is shifting. It’s not just wheat fields and wind turbines anymore. Giant, windowless boxes are rising from the basalt. The Amazon data center expansion Arlington Oregon is currently one of the most significant industrial shifts in the Pacific Northwest, yet most people driving past have no idea how much power—both literal and economic—is being packed into these dusty hills.
It’s big. Really big.
Amazon Data Services, the muscle behind Amazon Web Services (AWS), has been gobbling up land in this corner of the world for years. But the recent moves in Arlington and nearby Boardman represent a scaling effort that dwarfs their earlier investments. We are talking about billions of dollars. We are talking about thousands of miles of fiber optic cable. And, perhaps most importantly, we are talking about water and electricity in a region where both are becoming increasingly precious commodities.
Why Arlington? It’s Not Just the Cheap Land
You might wonder why a trillion-dollar company wants to hang out in a town with a population that barely cracks 600 people. Honestly, it’s a mix of geography and taxes.

Oregon’s enterprise zone program is basically a magnet for big tech. In Gilliam County, these zones allow companies like Amazon to dodge property taxes for a set period—usually three to five years—in exchange for creating jobs and meeting certain investment thresholds. For a facility that costs $200 million to build and houses servers worth even more, those tax breaks aren't just "nice to have." They are the entire point.
Then there’s the "Pueblo Effect." No, not the city in Colorado. It’s the idea of clustering. Once you have one data center, it’s cheaper to build the second, third, and fourth right next to it because the infrastructure is already there. The power lines are dropped. The high-speed fiber is buried. The cooling systems are mapped out.
Arlington sits in a sweet spot. It’s close enough to the massive hydroelectric dams on the Columbia River to get relatively green, reliable power, but far enough away from the seismic risks of the coast to keep the "five nines" of uptime that AWS customers demand. If the "Cloud" goes down, the world stops. Amazon ensures that doesn't happen by burying its brains in the Oregon desert.
The Scale of the New Build-Out
Let’s look at the actual footprint. The expansion isn't just one building; it's a campus approach.
The Port of Arlington has been a key player here. Recent filings show Amazon securing hundreds of acres of land near the industrial park. These aren't your typical warehouses. A standard AWS data center can be upwards of 200,000 square feet. Multiply that by three or four buildings, and you have a footprint that rivals some small cities.
- Phase One usually involves the "shell" construction. This is where you see the massive steel skeletons and the tilt-up concrete walls.
- Phase Two is the fit-out. This is the expensive part. Thousands of racks, cooling units, and backup diesel generators.
Wait, diesel? Yeah. Despite the push for green energy, these facilities need massive "uninterruptible power supply" (UPS) systems. If the grid flickers, those generators kick on in seconds. It’s a point of contention for environmental groups, but for Amazon, it’s a non-negotiable insurance policy.
The Water Problem No One Wants to Talk About
Data centers are thirsty. They generate an incredible amount of heat. Think about your laptop getting hot on your legs—now multiply that by 50,000 servers. To keep them from melting, Amazon uses evaporative cooling. Basically, they use water to chill the air.

In a dry climate like Arlington’s, this puts a strain on local aquifers.
There’s a tension here. Local officials love the "fees in lieu of taxes" because it funds schools and paved roads. But farmers in the region look at the water usage and start to sweat. Amazon has tried to mitigate this by promising "water positive" operations by 2030, which involves recycling water and investing in local watershed restoration. Whether that’s enough to offset the sheer volume of a multi-campus expansion remains a hot topic in town hall meetings.
Who Actually Works There?
Here is a reality check: data centers don't employ that many people once they are built.
During the construction phase of the Amazon data center expansion Arlington Oregon, the town is buzzing. Hundreds of contractors, electricians, and steelworkers fill up the local motels and diners. It’s a temporary gold rush. But once the doors are locked and the servers are humming? A skeleton crew runs the place.
You need:
- Security guards (lots of them).
- HVAC technicians to keep things cool.
- A handful of "smart hands" (technicians who swap out broken hard drives).
- Facilities managers.
We aren't talking about 2,000 office jobs. We are talking about maybe 50 to 100 high-paying technical roles per site. The real benefit to Arlington isn't the payroll; it's the sheer amount of cash Amazon pumps into the county's general fund through those enterprise zone agreements. For a small county, that money is the difference between a crumbling bridge and a brand-new community center.
The Connectivity Web
Arlington is a node in a much larger machine. It’s connected via "dark fiber" to Boardman, Umatilla, and all the way back to the "Hillsboro Ring" near Portland. This connectivity is what makes the Pacific Northwest one of the most important data hubs on the planet.
When you click "buy" on your phone or stream a movie, there is a statistically significant chance that the data is passing through a router in Gilliam County.
What Critics Get Wrong
People often call these "vampire buildings." They say they suck up power and give nothing back.
But it's more nuanced. Amazon is currently the world’s largest corporate buyer of renewable energy. They’ve invested heavily in wind farms right there in Gilliam and Morrow counties. In a weird way, the data centers are subsidizing the transition to green energy in Oregon because Amazon provides the "guaranteed buyer" status that wind developers need to get their projects financed. Without the data centers, many of those turbines you see on the ridges might not exist.
Future Outlook: AI and the Power Hunger
The recent pivot toward Artificial Intelligence (AI) is changing the specs for the Arlington sites. AI chips, like those from NVIDIA, run much hotter and require significantly more power than standard web-hosting chips.
This means the "expansion" isn't just about more buildings; it's about more power density. We are seeing Amazon upgrade the electrical substations in the area to handle massive loads. They are preparing for a world where generative AI requires a level of compute power that we can barely wrap our heads around today.
Moving Forward: What This Means for You
If you live in the region or are an investor following the tech footprint, here are the three things you need to watch.
First, keep an eye on the Port of Arlington’s public records. Any new land lease is a signal of the next phase. Amazon moves in "clusters," so if they buy one plot, they are likely looking at the three adjacent ones.
Second, watch the power grid. The Bonneville Power Administration (BPA) is under pressure to manage the load from these data centers without raising rates for residential customers. This will be the primary political battleground for the next decade.
Third, look at the local infrastructure. The "Amazon effect" in small towns usually results in improved fiber-to-the-home for residents as a side effect of the industrial build-out. If you're looking for a silver lining, it's that your Netflix might actually load faster because you live next to the source.
The Amazon data center expansion Arlington Oregon is a permanent shift in the Pacific Northwest's identity. The region is no longer just a "timber and wheat" economy. It’s the backbone of the global internet. Whether that’s a good thing depends entirely on how well the local government manages the influx of tech cash against the long-term needs of the environment.

Actionable Next Steps for Staying Informed
- Check the Gilliam County Planning Commission minutes: These are public documents that often reveal building permit applications months before an official press release.
- Monitor BPA Load Forecasts: If you want to know how big the expansion will truly get, look at the "interconnection requests" filed with the power authorities.
- Follow the Water: Keep an eye on the Oregon Water Resources Department (OWRD) for any new groundwater permit applications in the 97812 zip code. This is the clearest indicator of how many "chillers" Amazon plans to run.
The expansion is happening, whether the sagebrush is ready for it or not. The best way to navigate it is to understand that in the modern economy, data is the new oil, and Arlington just happens to be sitting on a massive well.
