A group of Norwell residents has embarked, once again, on the planning process aimed at replacing the town’s outdated 10,722-square-foot police station. In December, residents voted, 579 to 435, against a debt exclusion override that would have raised taxes to fund a 12,250-square-foot, $5.1 million facility attached to the fire station. At the time, Police Chief Theodore Ross called the loss disappointing, particularly because the planning process had been extensive. Ross said residents agree on the need for an improved station, but not on a solution. In May, the town announced it would restart the planning by gathering architectural bids, a process that recently closed. Now the town’s Permanent Building and Maintenance Committee will begin meeting as often as twice weekly to discuss the police station project, including finding a location for a new building.
