Residents are being asked to weigh in on whether to create historic districts in Norwell. An ad hoc committee appointed by selectmen last year has posted information about its mission, and work it has done to date, on the town’s website, www.townofnorwell.net. Stephen Hull, chairman of the Norwell Historic District Study Committee, said that residents on High, Main, and Summer streets were sent surveys last fall about creating historic districts. Because there wasn’t much response from residents on Main and High streets, a survey was recently mailed again to residents there. Once the committee hears from more residents in the areas that are being considered for local historic district distinction, it will put together a report and share the findings with the community.
