Digital Western Lands LLC, a subsidiary of Digital Realty Trust, is proposing construction of a data center campus and substations in Dulles.
The plans are listed in a July 19 notice with the U.S. Army Corps of Engineers.
The site is located northwest of the Dulles International Airport, within the Stallion Branch watershed, on an approximately 433-acre parcel southeast of the intersection of Old Ox Road (Route 606) and Beaver Meadow Road (Route 614) in Loudoun.
Digital Western Lands is proposing to construct Digital Dulles, a campus that will impact 4.91 acres of palustrine forested wetlands (PFO), 0.56 acres of palustrine scrub/shrub wetlands (PSS), 1.51 acres of palustrine emergent wetlands (PEM) and 420 linear feet of stream channels.
The applicant is required to obtain a permit from the Army Corps of Engineers to meet Clean Water Act and Virginia requirements.
In late 2018, Digital Realty Trust acquired approximately 424 acres from the Metropolitan Washington Airports Authority after signing a Letter of Intent to purchase the Dulles Airport’s Western Lands for $236.5 million.
The airports authority acquired several parcels of land west of Dulles International Airport from 2005-2007, totaling approximately 854 acres, to accommodate a fourth runway and additional support facilities, according MWAA staff.
The runway and the anticipated support area encompass approximately 414 acres, and the majority of the remaining acreage has remained undeveloped and underutilized, according to the authority.
The Corps of Engineers is soliciting comments from the public. Comments on the project should be in writing and can be sent by either email to firstname.lastname@example.org, or by regular mail, addressed to the Norfolk District, Corps of Engineers, Northern Virginia Field Office, 18139 Triangle Plaza, Suite 213, Dumfries, Virginia 22026, and should be received by the close of business on Aug. 11.
Loudoun County is home to more than 70 data centers, with most of them falling in the Ashburn corridor that has become known as “Data Center Alley.”
Digital Realty Trust is one of at least 3,500 technology companies in Loudoun, according to county officials. Eighteen million square feet of data centers are currently operational with millions more under development.
