133 Boston Post Road

Boston Properties has proposed a friendly 40B housing development and additional office space for the Biogen Idec/Monster site at 133 Boston Post Road. This proposal has been discussed with the Planning Board, Housing Trust, Board of Selectmen, School Committee and the Zoning Board of Appeals.

This project would help Weston meet its 10% affordable housing requirement and would help meet the housing needs and strategies identified in the Housing Production Plan. The Development Agreement for the site between the Town and Boston Properties will need to be amended, which will require approval by Town Meeting. 

This proposal has been discussed through the Planning Board, Board of Selectmen, various committees, and abutting neighborhoods before it went through extensive negotiations with the Planning Board. Background information is online.

Planning Board Negotiations


Several meetings with Boston Properties and the community have been held since May of 2017 and the Planning Board has enlisted input and analysis from engineering and financial consultants for traffic impacts and a fiscal impact analysis of the site's development.

Boston Properties presented new concept sketches to a neighborhood meeting on March 6, 2018 for a 275-unit project with 195,000 s.f. of office space, which can be viewed online here.

Planning Board Recommendations


The Planning Board met with the Board of Selectmen on March 27th to give its recommendations. Unfortunately, the Planning Board and Boston Properties were unable to reach an agreement on a development size that would be mutually consistent with the goals of both Weston and Boston Properties. Details are included in the March 26th memo to the Selectmen, below.

Next Step


The Board of Selectmen and Planning Board continue to assess the situation with Boston Properties, keeping in mind concerns expressed by abutting neighborhoods and the recent LIP proposal at 751 Boston Post Road. Modification to the Development Agreement at 133 Boston Post Road will need the approval of Town Meeting. 

The Zoning Board of Appeals has scheduled a continued comprehensive permit hearing for this project on January 9, 2019.
