The amendments, which were discussed at a recent Planning Board meeting, cover a range of issues, including business development, wireless communications facilities, and parking limits. The amendments are to be submitted to Town Meeting next month. The complete list of proposed changes has been posted online at www.town.northborough.ma.us.
