Many of the residents who attended a BRA get-together on a 138-condo complex proposed for Baker Street where it crosses the Needham Line opposed the idea, saying that's a bad location for so many cars - 210 parking spaces proposed- and worrying about the effect on already oversubscribed local BPS schools, according to Tim Sullivan, who attended the session at the West Roxbury Elks. He added a number of residents expressed doubts the BRA would really listen to their concerns.
