Bowing to the city's opposition to its plans, Suffolk University is giving up on the idea of putting a new dormitory tower on a Beacon Hill site. BRA director Mark Maloney told Suffolk Tuesday that the city was reversing its position and would oppose Suffolk's plans to house students at the site of a former Metropolitan District Commission building on Somerset Street. Outcry from the Beacon Hill community influenced the city's decision.Maloney suggested that the city and the neighbors may not be in as much of a hurry as Suffolk. "Interactive dialogue can be hard, and it's time-consuming, but it pays off," Maloney said. "We have to make sure we do this with the community, and they need a breather."
