Project Overview

The City of Somerville is making substantial systemwide investments to modernize its sewer and stormwater infrastructure. As part of this effort, the City will be installing new drainage infrastructure and rehabilitating the existing sewer system along Morrison Avenue (between Cedar Street and Grove St.) as well as throughout the surrounding neighborhood. This project will reduce flood risk in the surrounding area and help maintain the water quality of local rivers.

Prospective Timeline

City Staff from the Department of Infrastructure and Asset Management, along with consulting partners, are currently working on preliminary design for this project.

We anticipate sharing more information and initial design concepts at a community meeting to be scheduled in late spring/early summer 2024.

Final designs are currently anticipated to be completed by fall '25. Construction is anticipated to start in spring '26. All schedules are preliminary and subject to change.

    Over the coming weeks, City contractors will be performing geotechnical investigations along Morrison Avenue and nearby streets.

    Crews will drill to collect soil/rock samples and install observation wells in order to gather information about the existing soil profile.

    The information gathered will help the design team determine the suitability of the site for implementation of various utility tools/strategies as we pursue our project goals of reducing flooding and improving water quality.

    Schedule and Construction Impacts

    • Geotechnical investigations are scheduled to take place over the coming weeks. weekdays 7 a.m. - 3 p.m.
    • Work in any particular location is expected to be brief–ranging from a few hours to 1-2 days.
    • Some temporary parking restrictions will be required to facilitate work.
      • Please observe posted signage.

    If you have questions about this work, please email construction@somervillema.gov or call the Engineering Division at (617) 625-6600 x 5400.

    Schedule a Home Plumbing Survey

    To help better inform this project's initial design, the City and its consulting partners, Kleinfelder and Dewberry Engineers, are seeking to implement a home plumbing survey program. This program involves scheduling appointments with residents to perform a survey of their property and internal plumbing. This will require access to your basement or utility room. The goal of these surveys is to confirm existing connections between individual properties and the City’s sewer/drainage systems and identify existing surface drainage locations.

    If you live in or own a property listed here, we would like to perform a survey of your plumbing. Please click the link below to sign up and schedule a home plumbing survey. You will receive a form that requests permission to enter your property (with proper notice and coordination) to perform this plumbing survey. The information gathered will be used solely for the design of underground utilities on your street and will not be shared with other persons or parties outside of the project team.
