While many Prince George’s County officials have thrown their weight behind Greenbelt as a landing place for the new FBI headquarters, a massive Canadian developer is looking to change their minds.

The Walton Group’s proposal would swap part of its planned 479-acre Westphalia Town Center for the FBI’s much-maligned headquarters in the J. Edgar Hoover Building in downtown D.C. The company is already planning to build hundreds of apartments and townhouses, with retail space and a 150-room hotel, on the site, located on Pennsylvania Avenue just northeast of Joint Base Andrews.
