A developer has offered Fairfax County $166.8 million for part of a Chantilly police training campus, potentially placing a future data center alongside redesigned law enforcement facilities.
SCG Global Holdings LLC is seeking approximately 41.7 acres of the county’s 128-acre property at 3721 Stonecroft Boulevard. The proposed price works out to $4 million per acre.
Fairfax County received the offer last spring. At its Feb. 17 meeting, the Board of Supervisors is expected to consider scheduling a public hearing for March 17.
Residents will be able to comment before the board decides whether to enter into a purchase and sale agreement. County officials stressed that approving the land deal would not authorize construction of a data center, which would face a separate review process.
SCG appears to be affiliated with investment firm Starwood Real Estate Income Trust.
Sale could finance a campus overhaul
The Fairfax County Police Department has used the Stonecroft Boulevard property for training since 1993. It contains the Emergency Vehicle Operations Center and driver training track, along with firearms, rifle-range and K-9 training facilities.
The county also plans to build a new Criminal Justice Academy there to replace a facility at 14601 Lee Road that dates to 1983. The new academy is intended to help consolidate police training operations at the Chantilly campus.
That project is estimated to cost $88 million and is fully funded through public safety bonds approved by voters in 2018 and 2024.
If supervisors approve the land sale, the county plans to use the proceeds to redesign the entire training campus. That could release some bond funding for other projects.
Another $3.6 million remains from a 2015 bond referendum for replacing the Emergency Vehicle Operations Center and K-9 facility. The vehicle center was built in 1995 as a temporary structure, while county planning documents describe the K-9 facility as a small shed with severely limited space.
County staff said the redesigned campus would replace the driver training track, Firearms Training Center and rifle range, improving conditions for recruits and current officers while reducing long-term maintenance expenses.
Data center details remain limited
The size and design of SCG’s proposed facility have not been disclosed. County staff estimate, however, that the completed development could generate more than $20 million in local tax revenue during its first year of operation.
The property sits in an established industrial corridor south of Dulles International Airport and west of the Smithsonian’s Udvar-Hazy Center. It is surrounded by office parks and other data centers, and county officials said no residential development is planned or anticipated at the site.
Northern Virginia remained the world’s largest data center hub in the first quarter of 2025, with 4,900 megawatts of computing capacity and another 6,600 megawatts planned or under construction.
Additional Fairfax County projects are advancing in Reston, Lincolnia and the Dulles area, including one near a future high school. Penzance also broke ground last fall on a three-story Chantilly data center across Route 50 from the police training campus.
That growth has fueled opposition from residents and lawmakers concerned about noise, environmental effects, pressure on the electrical grid and proximity to neighborhoods.
In 2024, the Board of Supervisors adopted tighter zoning rules, including a ban on data centers within 200 feet of residential neighborhoods and an 80,000-square-foot limit for sites in most industrial districts.
Meanwhile, Virginia lawmakers are considering legislation intended to shift more energy costs to data centers and reduce the financial burden on residents and other electricity customers.
