The University Station proposal is hitting a sore spot with residents who say they are unhappy the development team has not submitted a mitigation plan for traffic and also question the financial projections. Residents attended a meeting with selectmen and the Planning Board in recent weeks and on Wednesday will bring their concerns to the School Committee. Superintendent John Antonucci has questioned estimates of another 55 students coming from the condo portion of the plan, which calls for 650 studio, one- and two-bedroom units. The project also calls for retail and office space and a 160-room hotel. Consultants say the upscale mall at the junction of Routes 128 and Interstate 95 will eventually generate an annual fiscal benefit of $5.9 million, less the $2 million in current property taxes. But residents like John Harding say a new fiscal impact study shows substantial costs to the town for increased police, fire, and other services, while no funding has been offered to address it. Wednesday’s meeting begins at 7:30 p.m. in the High School Little Theater, 200 Nahatan St.
