A series of proposed zoning regulation changes at the Connecticut Post Mall brought forth by Centennial, the mall owner, were denied by the planning and zoning board recently. The zone change application was denied, 7-3, with Peg Kearney, John Mortimer and Chair Jim Quish in favor, and Nancy Austin, Joseph Castignoli, James Kader, Brian Kaligian, Carl Moore, Robert Satti and Marc Zahariades voting against the plan. Some commissioners expressed concern that a regulation change would have unintended consequences during deliberations held Oct. 5 over the proposal, the public hearing for which was closed at the September meeting. The redevelopment project of the Connecticut Post Mall is planned to be completed in phases. Phase 1 would include about 300 apartments around a central plaza in the area formerly occupied by Sears Auto Service. Phase 2 includes demolishing the entire wing of the mall formerly occupied by Sears, which would free up 450,000 square feet of commercial space.
