The Planning Board on Feb. 14 will hold a public hearing on a proposal for a new Volkswagen dealership on Route 114 east. Cathleen Kavanagh, trustee of 72-74 Andover Street Realty Trust, which owns the property, has applied for approval of a site plan for the project. The plan calls for demolishing a Fiat dealership and constructing a 32,000-square-foot building on the 4.7-acre site, according to town planner Kate Day. The new single-story building would include a small mezzanine and provide space for a showroom, a service department, a parts storage area, an accessory car wash, and a dealership office area. She said the new dealership would be operated by Kelly Automotive Group. The meeting will be at 7 p.m. in the Toomey Hearing Room at Town Hall.
