A view of the NORTH DEKALB Rich's, which was sporting a Macy's moniker by the time this photo was taken. The store (while operating under the Rich's nameplate) had been expanded in the mid-1980s. The addition is the single-story portion seen at the front of the structure.

The 1980s reinvention was successful for a time, but -eventually- the shopping hub was in a downward spiral. A demalling was proposed by Hendon Properties in 2004. It would have demolished the existing Food Court and Main Entrance and inserted a new Costco. An "Ultimate Plan" would have demolished more of the original mall and cut a wide boulevard through the structure. Neither of these plans were carried out.
