Bowdoin College wants to buy a former assisted living home in Brunswick and turn it into student housing, but some town officials are concerned about the impact it would have on the neighborhood. The college signed a purchase and sales agreement in November, but can’t turn the building into a dorm unless the town approves a requested zoning change. Town councilors voted 8-1 last week to send the request to the Planning Board. The Times Record, reports that Councilor Sarah Brayman worried about the college expanding beyond its traditional footprint. Councilor John Perreault worried the town was showing favoritism to the college that might not be extended to a private citizen.
