Amazon Web Services (AWS) is planning to build a 1.75 million square foot data center facility in Loudoun County, Virginia.

According to Loudoun County records, Blue Ridge Group LLC, which is acting on behalf of Amazon, is seeking approval to rezone 100 acres at the Chantilly site from Mineral Resource/Heavy Industry to Planned Development-General Industry. This site is part of the $73 million land that Amazon acquired last year for the development of its data center.

The property is located near Dulles International Airport, to the immediate south and east are industrial utilities, including the Loudoun County Sheriff’s Office Firing Range and a mulch stockpile along Williard Road. The proposed facility will be joining over 70 data centers in Loudoun County, which is home to about 18 million square feet of data center space.

In March, AWS submitted an application to build three new data centers in Loudoun County with plans to fast-track the approval. Totaling about 300,000 square feet, the three data centers are to sit on a 90-acre land which Amazon acquired last year from Inova Health System Foundation for $116.4 million.

Also in Loudoun, Compass Datacenters is constructing its first data center in the County, where the company will be applying its 1.2MW incremental design principle to the campus model to achieve delivery timeframes in the process. The facility is expected to deliver 6MW of IT Load to the company’s cloud/hyperscale customers.

Expected to have been completed in Q1 2020, Boston-based data center operator Iron Mountain announced the construction of another data center on its Manassas Campus in Prince William County, also in Northern Virginia.

For this proposed AWS facility, the company’s applicant is also seeking approval to increase the Floor Area Ratio (FAR) from 0.4 to 0.6, thereby increasing the square footage of the new Loudoun County project.
