A circa-2011 physical layout of POTOMAC MILLS. The old Ikea and Waccamaw Pottery store structures have been replaced with a new Costco and 18-plex / IMAX. Bloomingdale's-The Outlet moved into the neighborhood in the summer of 2010. The mall lost a major tenant when the J.C. Penney Outlet Store shut down, in July 2011. However, it would eventually re-open as a conventional J.C. Penney operation.
