Boston Properties: 133 Boston Post Road

Boston Properties has proposed a 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, and School Committee and is currently before the Zoning Board of Appeals for a comprehensive permit.

The proposal calls for 345 rental units with 25% set aside at the 80% area mean income (AMI) and was discussed as a friendly partnership development in the Housing Production Plan. 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 total unit count is currently under negotiations.


Boston Properties is looking for a friendly process and wants to work with the Town. The Selectmen have signed a First Amendment to the 2008 Declaration of Restrictions with Boston Properties. This document provides conditional support for further investigation into this concept and specifies that school, traffic, and financial impact studies must be conducted, as well as a decrease in unit count and an alternate access road to the development (i.e. not Church Street). The Selectmen also signed an initial letter of support that was used by Boston Properties as a part of its site approval application to  Mass Housing, which was approved (documents are below). The project will continue through the public process through the Planning Board, as site issues are further discussed, and the Zoning Board of Appeals.


The traffic and financial impact studies have been conducted and are below. An alternate access road to the residential development has been proposed as Jones Road in Waltham, which is under city council review.  The Development Agreement with Boston Properties will also need to be modified, which will require a vote of Town Meeting in order for the proposal to move forward.
