Amazon could be using a site that was once a contender for its vaunted second headquarters as a distribution center.

An unnamed developer is under contract for a portion of Tilford Yard off Marietta Boulevard for a potential last-mile distribution hub, the Atlanta Business Chronicle reports. Tilford Yard is a more than 290-acre inactive rail property along the Atlanta BeltLine owned by rail giant CSX. The site was among those the state pitched to Amazon in 2018 as a potential HQ2 site, the ABC reported.

Amazon and CSX officials declined to comment on the deal.

“Amazon is a dynamic business and we are constantly exploring new locations and weighing a variety of factors when deciding where to develop sites to best serve customers," an Amazon spokesperson told the ABC.

Amazon has been the runaway leader of the industrial leasing pack in Atlanta — and across the country — over the past year, with its activity accelerating during the coronavirus pandemic as more consumers shopped online. The retail giant inked 6M SF of warehouse space across Metro Atlanta during 2020, giving it 13M SF in the region, according to Colliers.
