Cedar Street Water & Sewer Project
As an older city, Somerville's underground infrastructure is aging and in need of replacement; in the area of Cedar St., water mains are approximately 100 years old, or older. The combination of aging infrastructure, the need to minimize the frequency of flooding and continuation of the City's efforts to reduce its reliance on combined sewers, makes this a valuable project for the City.
In June and July 2016, the City of Somerville and its contractor, P. Giosioso & Sons Inc., began these needed improvements to the sewer, drainage, and water systems on Cedar St. (Highland Ave. to Elm St.) and Elm St. (Cedar St. to Somerville Ave.).

Dear Cedar Street Community Member,
Beginning on Monday, February 12 and lasting for approximately 2 weeks, Gioioso will begin replacing water valves in the intersection of Cedar St. and Highland Ave. While this work will not require the closure of the intersection, it will require lane shifts and some parking restrictions in order to allow two-way traffic to pass. This will be similar to the lane shifts created in November – December 2017, which generally caused minimal disruption. Work hours will be 7 a.m. to approximately 4 p.m., Monday through Friday (and if necessary, some Saturdays).
The timeline for the full closure of the Highland Ave./Cedar St. intersection has not yet been determined, however we are currently working on a detour plan as well as a communication plan so that when the dates do become available, we can share those with you immediately and with plenty of advance notice. This closure is dependent on the winter weather forecasts, among other factors, and may not take place until early March, but again we will be sure to give you advance notice as soon as the dates are available.
If you have questions or concerns in the meantime, please email [email protected], or contact the City’s Engineering Department at 617-625-6600 ext 5400.
Dear Cedar Street Neighbor:
This morning, you may have noticed a slightly altered traffic pattern at the intersection of Cedar St. and Highland Ave. Though two-way traffic continues to flow, the construction team currently working on the Cedar St. Water & Sewer Infrastructure Upgrade made the determination that, for safety, a lane shift at the intersection will be necessary for the next several weeks of the project. To accommodate the lane shift, there will also be minimal parking restrictions in the immediate area.
As the project has progressed toward the Highland Ave. intersection, larger construction equipment has begun to interfere with traffic on Highland Ave., making all forms of travel potentially unsafe if not for a lane shift to accommodate the equipment. Though it was the hope and intent of the City and the construction team to wait until after the holiday season to initiate this slight traffic pattern change, safety is always our first priority. This morning, it became evident that waiting was no longer an option. We apologize that we were unable to give you more advance notice of this change, though the lane shift is contained to a very small section surrounding the intersection itself.
As we approach much colder weather, the construction team is working diligently to complete major excavation and underground repairs within the next two weeks, at which time they will pave the entire length of Cedar St. (Elm St. to Highland Ave.), anticipated during the week of December 18. (NOTE: This is not the final pavement layer, but rather a temporary layer for the winter season.) Crews will then recess until after the New Year holiday, and work will resume at the intersection of Highland Ave. for approximately one month.
As work continues through January, we are exploring options to make this work as minimally intrusive as possible. Two options we are currently exploring include:
- Continue work during weekdays, with slight lane shift in place during working hours (7am-7pm).
- Conduct this work overnight, leaving the road open during the daytime. There will be noise associated with the work, in the vicinity of Highland Ave. & Cedar St. intersection.
We welcome your input on both options so that we can reach a decision that makes the most sense for abutters. If you have input you would like to share, please email [email protected] as soon as possible.
Again, we apologize for any inconvenience. If you have questions or concerns about this phase of work, please contact the City’s Engineering Department at 617-625-6600 ext 5400.
Construction Update & Upcoming Construction Schedule
Gioioso continues to make progress between Summer St. and Highland Ave., and work has now progressed beyond Hall Ave. As we near the end of the construction season, our goal and the contractor’s goal is to be able to complete all necessary work below the road surface before the end of the season. To accomplish this, crews may need to work into the evening hours. Work will not continue past 7 p.m. except in urgent situations, in which case you will be notified separately. Additionally, crews will plan to work on Saturdays, between 9 a.m. and 7 p.m., over the next several weeks. This will enable crews to complete the work and to pave a temporary layer of pavement before the weather becomes too cold to do so. Typically, the “winter moratorium” on street excavation and construction takes effect in mid-November. With the unseasonably warm weather, this moratorium may be later than normal, but we will be sure to keep you informed as to the official end of the construction season.
IMPORTANT NEW INFORMATION: Beginning on Monday, October 30 (weather permitting), construction crews will need to do additional work to secure the water bypass at the intersection of Cedar St. and Highland Ave. For this work, No Parking will be posted in the immediate vicinity in order to allow two-way traffic to flow on Highland Ave. This work is expected to take approximately 5 days to complete.
Please note that when crews complete work for the evening, they will do their absolute best to keep driveway access clear. Due to the size of the machinery, sometimes this is unavoidable. In these instances, crews make every effort to alert residents, however where possible we suggest parking outside of your driveway in the immediate work zone in order to avoid unintentionally being blocked in. If you do find yourself blocked in and you need urgent assistance, please call 311 and we will contact the project team.
If you have any questions, please call 311 (617-666-3311). Thank you.

Work in the Summer/Cedar intersection will include excavation of the pavement with the use of jackhammers. Crews will complete upgrades to underground water & sewer infrastructure and other necessary utilities, as well as upgrades to electronic signaling. This work is expected to take approximately one month to complete.
If you have any questions, please contact the Somerville Engineering Department at 617-625-6600 ext 5400.
Beginning on August 7, P. Gioioso will resume work on Cedar St., between Sartwell and Summer. Work had been delayed due to necessary remediation by Eversource, but crews will resume scheduled construction next week.
P. Gioioso & Sons completed repaving on portions of Elm St.
Upcoming Construction Schedule
Blasting and jackhammering will begin again on August 7 between Sartwell and Summer, though the end of this phase of construction is in sight! Within the next three weeks, Gioioso anticipates that they will move into the intersection of Cedar St. and Summer St. Once those details become available, and when we have a clear understanding of the schedule, abutters will be notified with at least 2 weeks notice (where possible). Please stay tuned for those updates!
NOTE: If you are moving into or out of a home in a designated work zone, please be advised that PODS will not be allowed in these areas during the construction period. Parking permits for moving trucks or moving vans should be obtained 10 days in advance in order to allow staff to determine the safest place for the trucks. If you have questions, please call 311.
Last week, a minor accident occurred when a contractor fell into an open trench on the construction site. Although the situation was serious, the nature of the injuries was not serious. Following proper protocol, Gioioso has stopped regular operations on site until review and repairs are complete, which we anticipate will be early next week. Until that time. Cedar Street will remain open to through traffic. Please note that at no time was there any danger to the general public nor to abutters on Cedar Street.
Last Week's Accomplishments
Over the last two weeks, Gioioso began blasting operations near the intersection with Summer Street. The work has been successful thus far, and work will continue early next week. We anticipate that blasting will continue through approximately August.
Upcoming Construction Schedule
Once regular construction operations resume next week, blasting and jackhammering will continue, and Cedar Street will be closed to traffic between Summer Street and Sartwell Ave. During those times, abutters may access homes via Sartwell Ave. Unless otherwise noted, Cedar Street will be open to traffic during weekends. Also next week, paving crews will begin final repairs to sidewalks along Elm Street, though no closures are anticipated at this time. We will continue to update you as construction progresses, however should you have any questions, please contact 311 (617-666-3311), or the Engineering Department. Thank you!
Beginning on Monday, June 5, and lasting for approximately 2 months, construction will take place Monday through Friday, from 7 a.m. to approximately 3:30 p.m., and will include jackhammering and blasting. Blasting is anticipated to take place once per day, and residents will be warned in advance with the use of air horns.
Beginning on Monday, Cedar Street between Summer Street and Sartwell Ave. will be closed to through traffic. Abutters will be able to access homes via Sartwell Ave., which will be temporarily converted to accommodate 2-way traffic. This portion of the street will remain closed at all times during week days and weeknights, and will reopen each weekend. Through traffic will be detoured onto Cherry Street or Linden Ave.
If you have any questions or concerns, please call 311, or the City’s Engineering Department at 617-625-6600 ext. 5400.
Improvements Above and Below Ground
Improvements during this project include upgrades to both underground water & sewer infrastructure as well as surface-level roadway improvements for cars, bicycles, and pedestrians. During the first phases of construction, crews will address the major underground infrastructure work (which may mean some temporary water service disruptions, in which case residents will be notified in advance). In later phases, Cedar St. will be repaved, new, ADA compliant sidewalks added, and bike lanes striped. In all, the project will include:
- Improving the drainage system
- Reducing the frequency of flooding events at Hall St.
- Separating sewer & drainage systems
- Installing new water mains
- Installing ADA compliant sidewalks
- Repaving Cedar & (portions of) Elm Streets
