A new 4.25 million square foot (394,800 sqm) data center campus is being proposed in Bristow, Virginia.

First reported by Inside NoVa, Virginia-based developer Stanley Martin is seeking to rezone more than 250 acres in Northern Virginia’s Prince William County on a site it had previously earmarked for a housing development and adjacent to another upcoming data center development.

The company has filed an application with Prince William County for a Comprehensive Plan Amendment to change 269.85 acres between Linton Hall Road and Devlin Road from Suburban Residential Low (SRL) to Flexible Employment Center (FEC) for data center uses. The Comprehensive Plan amendment was submitted in February and comes ahead of a planned rezoning application.

The project is known as the Devlin Technology Park; the zoning change would allow for up to 4.25 million sq ft of development.

The current land use designation allows for 1,079 single-family units, for which Stanley Martin was granted zoning approval in 2020. At the time, the property was owned by Edith Rameika, trustee of the EV Hunter Trust. Since then, Stanley Martin has reportedly acquired the property for nearly $51.3 million.

Rameika was also owner of properties adjacent to the Stanley Martin land that was approved for data centers in September 2021; possibly for Yondr’s upcoming campus.

In 2015, the Stonehaven development was pitched to bring 1,006 residential units and 1.1 million sq ft (102,200 sqm) of commercial space to 718 acres. The Stanley Martin proposal first came to the county’s Planning Commission in September 2018.

Stanley‐Martin became part of Japan's Daiwa House Group in 2017. This would seemingly be the US firm's first data center project, though Daiwa has previously been involved in such developments in Japan.
