A Virginia county hosting over 250 data centers, including Loudoun, has revised zoning policies to require formal approval processes for new facilities, responding to resident pushback.

Loudoun County, Virginia, located just 22 miles west of Washington, D.C., holds the greatest concentration of data centers in the United States, with more than 250 facilities operating within its borders. After more than a quarter-century of leveraging this industry, the county is beginning to rein in construction in response to growing resident complaints. The region’s data center boom originated from federal government demands for fiber internet infrastructure, amplified by its proximity to the nation’s capital. During the dot-com craze of the late 1990s, numerous companies deployed extensive fiber networks throughout the area, establishing it as an ideal hub for early data centers. This trend accelerated when AOL relocated its headquarters to the region in 1996. By 2000, Loudoun County voted to classify data centers as office parks, allowing developers to construct these facilities with minimal oversight or regulatory approvals.

This regulatory environment incentivized major technology firms to invest heavily in the area. By 2007, Loudoun hosted 29 data centers, a figure that grew nearly ten-fold over the following two decades. Initially, the negative impacts of these projects were negligible, and residents largely welcomed them for the substantial economic benefits they delivered. Data center revenue surged from $150 million in 2015 to $1.1 billion in 2025. This financial windfall enabled the county to reduce property taxes to just $0.805 per $100 of assessed value—less than 0.8%, ranking among the lowest in the United States, particularly for a suburban jurisdiction. Beyond tax relief, the revenue funded significant public improvements: two new schools were opened with a third currently under construction, a $102 million recreation center featuring multiple pools and hydro-massage chairs was built, and $22 million was allocated to convert a former presidential estate into a public park. Additionally, the county expanded its fire and emergency services while maintaining its roads, bridges, and toll infrastructure in excellent condition. Consequently, many residents remain supportive; at a July town hall meeting addressing the industry, attendees wore shirts reading, “I Support Data Centers Because I Like: Lower Taxes, Excellent Schools, Better Job Opportunities, and More.”

This local prosperity stands in stark contrast to nationwide trends surrounding data center development. Across the country, new facilities have sparked widespread opposition due to electricity price increases of up to 76% in the largest U.S. power grid, excessive water consumption that has reduced supply pressures for neighboring communities, 24/7 noise pollution rendering areas unlivable, and allegations of air pollution from unpermitted gas turbines used to power operations. In response, numerous counties and states have enacted moratoriums on new developments. Despite Loudoun’s historical acceptance, sentiment is shifting. Juli Briskman, a Loudoun Board of Supervisors member overseeing land use, zoning, and economic policy, stated, “It’s gone way too far. We’ve become addicted to the data centers for their tax revenues, but at what cost?” Residents have begun voicing specific grievances regarding recent projects. A newly operational Vantage data center faced noise complaints stemming from its diesel and gas turbine generators, while an Ashburn-area resident raised concerns over Dominion Energy’s plans to install an 185-foot-tall high-voltage electricity transmission tower near her home. Furthermore, reports indicate that a technology company is purchasing over 100 homes in a luxury community for $4 million each—double their current market value.

In direct response to these mounting concerns, Loudoun County has officially ended its policy of zoning data centers as office parks. Developers seeking to build in the area must now navigate a formal public approval process, significantly slowing project timelines and offering no guarantee of authorization. Just last month, Amazon submitted applications to construct four additional data centers in the region, with several board members already signaling intent to reject the proposals. When managed responsibly, data centers can deliver substantial economic prosperity to host communities, precisely the outcome Loudoun County achieved. It is important to note that these facilities do not solely support artificial intelligence; they also underpin the broader digital economy, ensuring the smooth, large-scale operation of online services such as Facebook, Instagram, Netflix, Spotify, Google Maps, and Uber. However, the immense processing power required for AI workloads means modern data centers consume vastly greater amounts of electricity and water. Without proactive local government intervention to safeguard community interests, living adjacent to these facilities has become increasingly untenable for residents.
