The Board of Selectmen has scheduled an informational meeting about affordable housing in town for Feb. 28. Of particular concern are residents’ reactions to and questions about a proposed 96-unit development on West Street. “Given that high level of concern, it is important for people to learn just what can and cannot be done once a 40B is proposed,’’ said Selectman Osler Peterson, referring to the chapter of state law that guides affordable housing of the kind in question. “In general, unfortunately, a town’s options are truly limited.’’ The time and location of the meeting are forthcoming at town.medfield.net. According to Peterson, the town administrator has described the proposed units as being 100 percent affordable-housing type residences. - James O’Brien
