Project Area Map

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 constructing a new stormwater outfall pipe which will discharge to the Mystic River, installing new drainage infrastructure, and rehabilitating the existing sewer system in the neighborhood west of Foss Park. 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.

Preliminary designs are expected to be completed by Fall 2024. Final design is expected to be complete in 2025.

    For those unable to attend, the meeting recording and presentation will be shared here shortly after the meeting.

    Schedule a Property Drainage Survey

    To better inform this project’s initial design, the City and its consulting partners, Stantec and Dewberry Engineers, will be conducting an external property drainage survey program. The goal of this program is to confirm existing connections between individual properties and the City’s sewer and drainage systems and to identify existing surface drainage locations. During each survey, a Dewberry or Stantec staff member will enter your property grounds to assess yard drainage features. Staff will need to be granted access to enter the property but will not need to come inside of any building.

    If you live in or own a property listed here, we would like to perform a survey of your property drainage features. 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.
