The town has hired David J. Field to be director of the Department of Public Works as well as town engineer, a post that had been vacant for many years. Field, who lives in Attleboro, is director of engineering for Dedham, said Town Administrator David A. Colton. Field, a 1997 graduate of the University of Massachusetts in Dartmouth, will take the lead role in completing the town’s comprehensive wastewater management plan, the revitalization of North Easton Village, the renovation of Frothingham Hall, and multiple roadway and intersection projects, Colton said. He assumes the post, being vacated by Wayne Southworth, on Feb. 13. - Steve Hatch
