What happened

The commission deferred final approval of a home rebuild at 15 Otis Street to November 5, citing concerns that invasive knotweed on a steep slope could compromise new retaining walls above a wetland. The body approved replacement of a failing 35-year-old septic tank at 8 Phillips Pond Road and a one-story addition at 84 Cottage Street. Staff reported an escalating dispute with MassDOT over a drainage discharge that the agency claims is exempt from state permitting.
