Project Coordination and Construction Activity

The Commission is committed to working closely with the Mayor's Office: elected officials; Boston Public Works Department (BPWD), Boston Transportation Department (BTD), and other City departments; other public and private utility companies; state and federal regulatory agencies; and, most importantly, with abutters to ensure the project is successfully completed. Effective coordination will also help mitigate many short-term construction related impacts that may be associated with the project.

Community Relations Program

The Commission is committed to a proactive community relations program during construction of this project. The program is designed to keep residents, businesses and elected officials informed about the project by holding public meetings, placing notices in local newspapers and posting updates on the project webpage, which will be available on the Commission's website at:

Before construction begins on a section of the street, a notice will be sent in the mail. The contractor is required to provide 48-hour notice to abutters for any anticipated water interruptions. Advisories and periodic updates and notices will be distributed to the project email list and on the Commission's website. Project staff will meet periodically with residents, businesses, civic groups, and elected officials to provide updates, as requested or appropriate.

Commission staff will work closely with affected abutters regarding issues such as pedestrian and vehicular traffic management, access to residences and business establishments, and maintaining access for deliveries and trash removal. The Commission will coordinate access and water interruptions with individual businesses and property owners/managers affected by any water main replacements.

During construction hours, a full-time Inspector will be onsite. To ensure a timely response, any concerns or questions should be addressed to field personnel. Contact the BWSC Inspector onsite or at the phone numbers listed in the Project Contacts box to the right.
