Bowman, of Miller, Wolff, Napolitano LLC, says Monday night’s vote comes after “a long 20 years” of various efforts to transform several lots on the north end property into a complex that is now projected to feature a gas station and a convenience store, a hotel, a grocer, restaurants, and other anticipated retail uses, along with new housing already underway. Commission members were largely enthusiastic in their comments following the public hearings on a series of applications, which did not draw any public input. In a separate set of waiver applications, project engineer Darin Overton, of SLR Consulting, described some of the earthwork plans. In order to create a flat pad for the retail stores, the level of the development will be below the level of Route 10. The work will also involve disturbing more than five acres at a time, due to the scope of the project.
