The once-in-a-generation planning effort that goes by the name "Plan JP/Rox" has started to produce specifics about what our neighborhood will look like. Here's the vision for Green Street. Green Street: This area between Amory and Washington Street is identified as neighborhood commercial center of mixed use buildings and "21st century commercial business" spaces are proposed for the rear of the BMS paper company at 3390 Washington Street and at Amory Street next to Bartlett Square I where the Interstate Trucking yards are located. "The most important part of this," said John Dalzell, a senior architect for the Boston Redevelopment Authority, "is a need for mixed commercial business on the ground floor. Some business are new and don't have that obnoxious quality about them."
