Millennium Partners has been approved to build a tower on the former site of the Winthrop Square Garage.Though the garage itself was not historically significant, the site at Winthrop Square joins the Financial District and Downtown Crossing in historic downtown Boston and is near a number of historically significant sites, buildings, and landscapes. The building will have a range of impacts from the pedestrian realm to the skyline and has therefore undergone review and scrutiny by the City, the Boston Planning and Development Agency (BPDA), neighbors and abutters, and organizations like the Alliance. However, it received a certificate of compliance from the Mass. Secretary of Environment (MEPA Certificate) that was contingent on completion of Consultation with the Mass. Historical Commission, which is still in process.


Alliance Involvement 

In the summer of 2016 six development teams presented proposals to purchase and redevelop the City-owned Winthrop Square garage site. Ultimately, the proposal by Millennium Partners was selected and the process of reviewing the specific project began. The Alliance publicly opposed a change in state law that was necessary to facilitate a tower on this site. The purpose of the law was to protect our historic open space (Boston Common and Public Garden) from shadow and intrusive development and we felt that changing state law to facilitate one project was inappropriate and poor precedent. The law was successfully changed, however, and the Alliance engaged with the proposal as it evolved over time. Through several public meetings, comment letters, and meetings with the project team, the Alliance was able to express concerns about the impacts of the tower on historic resources and move towards mitigation efforts with the proponent which are ongoing.

However eliminating the shadow bank does not mean that no future shadow can be created by new development.
