The contractor will be working on Saturday, October 3, between REI and 401 Park Drive forming the sidewalk in preparation for plans to pour the sidewalk on Monday, October 5.


The fence line in front of 421 Park Drive has shifted to allow for more accessibility for pedestrians and cyclists. Punchlist work is ongoing throughout the interior of the building and around the exterior largely inside the site fence.


There is some hardscape and streetscape work taking place on Fullerton Street in coordination with the City of Boston. The street is scheduled to be milled and paved in the October/November timeframe. The contractor is doing the work needed to support some new planting beds. More details and dates will be shared once they become available. 


A landscape contractor began the initial phase of streetscape improvement work on Aberdeen Street in mid-September, and the work has been progressing towards Beacon Street. Planned improvements include replacement of the existing streetlights, the addition of at least one new streetlight, and installation of some raised planter boxes and a privacy fence at the end of the street that abuts the MBTA tracks. The utility work for the streetlights is expected to last approximately six weeks followed by about two weeks of work on the privacy fence and planters. Work hours are Monday through Friday from 7:00 am to 3:30 pm. The contractor is setting up and coning off work areas in the street in sections along the curb line so the contractor can excavate and create a trench for new electrical conduit to support the new light poles. Street parking spaces are coming offline temporarily to accommodate each of these work areas as the contractor makes their way up the street. 


As of last Wednesday, September 30, the trench extending from approximately 7 to 21 Aberdeen had been backfilled with soil, and the contractor moved the work area down the street, setting up the next and final section along the curb line close to the corner of Aberdeen and Beacon Streets. About four street parking spaces in this area had to come offline. Street parking is now available in front of 7 to 21 Aberdeen Street. A police detail has been requested to support the work and assist with traffic. When a detail cannot be filled, the laborers will help guide vehicles needing access to Aberdeen, including the garbage trucks. Neighbors can expect some noticeable noise during work hours, particularly during the excavation portion of the work. The properties on Aberdeen Street are being notified separately about the work plans and impacts to the street.
