Inside Data Center Alley’s growing impact on Loudoun neighborhoods
Loudoun County, Virginia, known as "Data Center Alley," is grappling with the extensive growth of data centers and their impact on housing affordability, land use, and local infrastructure. Residents and officials express concerns about the conversion of residential land, rising land values, and the environmental and aesthetic toll of these developments, including massive power lines. Despite the significant tax revenue generated, the community is increasingly questioning the overall cost of this rapid expansion.
Loudoun County, Virginia, home to approximately 200 existing data centers and another 100 planned, is grappling with the societal and environmental impacts of its rapid growth as "Data Center Alley." While data centers contribute over 40% of the county's property tax revenues, local officials and residents are increasingly concerned about the downsides.
Algonkian District Supervisor Juli Briskman highlighted how the rezoning of residential land for data centers exacerbates Loudoun County's housing affordability crisis and hinders economic diversification. She noted that constant land purchases by data center companies drive up land values, pushing out residential developers and making it difficult for younger generations to afford to live in the area. Residents from communities like Ashburn, Sterling, Hamilton, and Purcellville are expressing concerns about unsightly power lines, increased infrastructure demands, and the overall environmental footprint, including potential impacts on water, power, and air quality.
On June 22, Rep. Suhas Subramanyam (D-10th Congressional District) hosted a town hall where constituents voiced grievances about data center expansion, specifically mentioning issues like above-ground power lines and the strain on local infrastructure. The electrical grid serving these facilities is a long-standing point of contention; the Virginia State Corporation Commission recently approved Dominion Energy's plan for 185-foot transmission lines through neighborhoods, with one even slated for a resident's backyard. Officials like LCSB Chair April Chandler acknowledge the continued demand for data centers and emphasize the need for a thoughtful, deliberative approach to future development.
