BRUNSWICK, Maine (AP) – Brunswick’s Planning Board has approved a zoning change that opens the door for Bowdoin College to convert a former assisted-living facility near campus to student housing. The college agreed late last year to buy the building on Harpswell Road, but needed the town to change the zoning to turn it into a dormitory. The board this week voted 4-1 to approve the change. The Times Record (http://bit.ly/ZtuE2S ) reports that a Bowdoin official says acquisition and renovation of the building is part of the college’s ongoing effort to consolidate students who are now scattered around town. The college has assured neighbors that the dorm will be “chemical-free quiet” housing. The zoning change now goes to the town council for a public hearing.
