Construction Details

Water & Sewer Work

Over the next three weeks, National Water Main crews will continue cleaning sewers along the eastern end of Somerville Ave. Expect isolated lane shifts and temporary no parking zones between Webster Ave. and Medford St. There are no expected impacts to water service as a result of this cleaning.

Barletta crews continue to replace the old water main beneath the Plaza. Last week, the final portion of existing water mains were moved onto temporary mains. During the week of July 16, water work will continue on the Plaza and Somerville Ave. at the intersection with Bow St. In approximately two weeks, this work will move east toward El Potro and Reliable Market. While there will be no water service interruptions, sidewalk cafes and furniture in this area will be moved as crews complete the work. If you are a business owner in this area and have concerns about the work, please contact the City’s Construction Compliance Manager, Jesse Moos, at [email protected].

Somerville Ave./Plaza Work Zone

Excavation will continue in the Plaza for several weeks, however the existing fenced-in work zone will become smaller as of Tuesday, July 17, the crosswalk will fully re-open, and the work zone will be moved to extend from Stone Ave. to just east of the MBTA bus stop and the crosswalk. As of Friday, July 13, the MBTA bus stop at that area was restored to its normal location,. While the work zone remains in place, bicycle traffic should continue to share the lane with motor vehicle traffic on Somerville Ave. westbound. 

Work at Bow St. and Webster Ave.

This week and next week, expect isolated lane shifts and lane closures on Bow St., where Barletta will be conducting water work, and within the Somerville Ave./Webster Ave./Washington St. intersection, where Eversource Electric will be test-pitting. Bikes will be directed to share the lane with motor vehicle traffic.

During the week of July 23, Eversource will begin relocating duct banks in the Somerville Ave./Bow St./Stone Ave. area for approximately three months, requiring lane shifts and closures. Bikes will be directed to share the lane with motor vehicle traffic.

Highlights to Note (See Below for More Details)

  • Isolated lane shifts for vehicles on Somerville Ave. between Webster Ave. and Medford St. beginning July 2.  
  • Bicycle traffic should continue to share the lane with motor vehicle traffic on Somerville Ave. westbound while the work zone is in place.
  • Isolated water service interruptions expected the week of July 9.
  • Due to the holiday, construction work will stop by noon on Tuesday, July 3, and resume Thursday, July 5, at 7 a.m.

Construction Updates

Beginning the week of July 2, National Water Main crews will be cleaning sewers along the eastern end of Somerville Ave. Drivers should expect isolated lane shifts around manholes between Webster Ave. and Medford St. so that workers can safely access those sewers. On-street parking may also be affected depending on the location of the work at a given time. These cleanings are expected to takeabout three weeks to complete. There are no expected impacts to water service as a result of this cleaning.

Barletta crews are also making progress as they work toward replacing an old water main beneath the Plaza. To do so, they need to set up temporary water service, remove the old main, then install the new piping. During their overnight operations this past week, they began this process by cutting into the main water line and installing two new valves. Prior to installation, the temporary water system will be tested the week of July 2, and once it’s determined to be working safely and effectively, select building services will be transferred from the old water main to the temporary water line.

During this cutover, anticipated for the week of July 9, a small subset of properties in the area will experience a short interruption to their water service. This interruption is only expected to last about one to two hours, and impacted properties will be notified directly by the City.

Excavation continues in Union Square Plaza as Barletta works to replace a 24-inch sewer line. The fenced-in work zone in the Plaza is expected to remain in place until late July. During this time, bicycle traffic should continue to share the lane with motor vehicle traffic on Somerville Ave. westbound.

Please note that construction will wrap up by noon on Tuesday, July 3, for the Fourth of July holiday. Work will resume Thursday, July 5, at 7 a.m.

Highlights of Upcoming Work (See Below for Full Details)

  • Overnight water work will be conducted in the Union Square Plaza the nights of Monday, June 25, and Tuesday, June 26, from approximately 9 p.m. to 5 a.m. the following morning. Some properties will experience interruptions to water access during this time, but all those affected will be contacted directly by the City.
  • As of this week (June 14), and continuing until approximately the week of July 16, westbound bicycle traffic will be directed to a shared lane with motor vehicle traffic in front of the plaza, on Somerville Ave. 

Overnight Work & Water-Service Disruptions

Overnight work will be conducted in the plaza the nights of Monday, June 25, and Tuesday, June 26, from approximately 9 p.m. to 5 a.m. the following morning, in order to perform necessary tie-ins to existing water systems. This work has been planned during overnight hours in order to be as minimally impactful to residents and businesses as possible, particularly as there will be some water service interruptions during this work.

During these times, crews will be performing work involving two local waterline tie-ins, so some properties in the area will experience interruptions to their water service between 9 p.m. and 5 a.m. All properties that will be affected will be contacted directly by the City within the next week.

Residents may hear intermittent, moderate noise overnight while the crew’s compressor is running and when workers are sawing into pipes. Project staff ultimately chose to conduct this work overnight, however, in an effort to minimize disruptions to the community and to avoid interrupting residents’ water access during daytime hours.

Construction Updates

Crews have completed test pitting operations within the intersection of Prospect St. and Somerville Ave. and will continue to test pit the east end of Somerville Ave. (toward Medford St.).

Excavation to replace a 24-inch sewer line at the south edge of the Union Square plaza began this week, just west of the mid-block crossing at the plaza, and will continue toward the east side of Stone Ave. on Somerville Ave. westbound. 

A fenced-in work zone was set up in the plaza on Tuesday, June 12, which will remain in place for approximately five weeks, including on weekends. During this time, bicycle traffic will be directed to the shared lane with motor vehicle traffic on Somerville Ave. westbound.

Please note that the MBTA bus stop on Somerville Ave. at the Union Square plaza has shifted approximately 100 feet east toward Prospect St., near the Somerville Media Center building, to accommodate construction for the foreseeable future. 

Preconstruction Surveys

Pre-construction property surveys are underway. Pre-construction surveys include visual inspections of the exteriors and interiors of buildings using video, photographs, or a level survey that measures elevations of basements and ground floors. All inspections will be performed in the presence of the engineer and property owner or their designee.

Both the City and Barletta have sent multiple notices to property owners designated for pre-construction surveys. If you are unsure if your property was included, please reach out to a member of the project team listed below.


Updated 6/3/2018

Below are some project updates for your information:

  • Tree removals will now begin Wednesday, June 6. To see the locations of these trees and a list of trees to be replanted at the completion of the project, click here.
  • The MBTA bus stop on Somerville Ave. adjacent to the Union Square Plaza will be shifted about 100 feet east (toward Prospect St.) on or around Thursday, June 7.
  • Effective this week, westbound bicycle traffic will be directed to a shared lane with motor vehicle traffic in the plaza between 7 a.m. and 3 p.m.

Tree Removals

Due to a schedule adjustment, tree removals will now take place on Wednesday, June 6, weather permitting. Four trees in the Union Square plaza and five trees on the south side of Somerville Ave., between Bow St. and Prospect St., will be removed at that time. Almost all of these nine were found to be in poor health by the City’s arborist. In total, 37 trees are scheduled to be removed throughout project. Trees allocated for removal that are west of Allen St. are scheduled to be removed over the course of the 2018 construction season. Trees allocated for removal that are east of Allen St. are planned for removal in 2019. 40 trees will be preserved throughout construction, and 51 new trees will be planted at the end of the project. Visit www.somervillema.gov/somervilleaveto view the presentation materials from two tree hearings held in 2018, a list of trees that will be removed, and a map showing the nine that will come down Wednesday.

Upcoming Construction Schedule

Beginning the week of June 4 and continuing for approximately six weeks, excavation will occur to replace a 24-inch sewer line at the south edge of Union Square plaza, just west of the mid-block crossing at the plaza, and will continue to the east side of Stone Ave. on Somerville Ave. westbound. This work will include a work zone in the plaza itself and will also impact the bike lane and westbound travel line. Bicycle traffic will be directed to the shared lane with motor vehicle traffic on Somerville Ave. westbound during work hours (between 7 a.m. and 3 p.m.).

The MBTA bus stop on Somerville Ave. at the Union Square plaza will be shifted approximately 100 feet east toward Prospect St., near the Somerville Media Center Building, to accommodate the sewer installation. The bus stop relocation will occur on or around Thursday, June 7. Please review all posted signage.

Preconstruction Surveys

Last week, contractors from Barletta Heavy Division sent letters to property owners in specific areas notifying them about pre-construction property surveys. The purpose of pre-construction surveys is to document existing property conditions prior to construction. While not required, the surveys provide important documentation should property owners notice damage to their property during or after construction. Without proper documentation of conditions before construction, it may be difficult to demonstrate how or if damage may have been done to a particular property as a result of the project. Preconstruction surveys include visual inspection of the exteriors and interiors of buildings by means of video, photographs, a level survey giving elevations of basements and ground floor. 


If your property is impacted, building owners should already have received notice from the City and from Barletta. 

All inspections will be performed in the presence of the Engineer and property owner or their designee.


Updated 5/23/2018

Upcoming Construction Schedule

During the weeks of May 21 and May 28, contractors will continue digging test pits intermittently along Somerville Ave. between Bow St. and Prospect St., and also between Prospect St. and Medford St. Test pits are a common construction practice. Prior to the start of any excavation, construction crews dig small “test pits” to be sure that the underground infrastructure and utilities are in proper order and that the construction plan can proceed accordingly. Typically, test pits are only several feet wide and do not involve significant work or impacts to abutters, however this work will require some lane shifts, closures, and parking restrictions in various locations along Somerville Ave., just west of Prospect Street to Medford Street, between 7 a.m. and 3 p.m. No Parking signage will be posted 48 hours in advance of the parking restriction at test pit location. Please review any posted signage when parking in this area as signage and timing may change. 

Beginning the week of June 4 and continuing for approximately six weeks, excavation will occur to replace a 24-inch sewer line at the south edge of Union Square plaza, just west of the mid-block crossing in the plaza, and continue to the east side of Stone Ave. on Somerville Ave. westbound. This work will include a work zone in the plaza itself and will also impact the bike lane and westbound travel line. Bicycle traffic will be directed to the shared lane with motor vehicle traffic on Somerville Ave. westbound during work hours (between 7 a.m. and 3 p.m.).

The MBTA bus stop on Somerville Ave. at the Union Square plaza will be shifted approximately 100 feet east, near the Somerville Media Center Building, to accommodate the sewer installation. The bus stop relocation will occur sometime during the week of June 4, 2018. Please review all posted signage.

Preconstruction Surveys

Beginning the week of May 21, contractors will be contacting property owners in specific areas to conduct pre-construction property surveys. The purpose of pre-construction surveys is to document existing property conditions prior to construction. While not required, the surveys provide important documentation should property owners notice damage to their property during or after construction. Without proper documentation of conditions before construction, it may be difficult to demonstrate how or if damage may have been done to a particular property as a result of the project. Impacted properties will be notified directly by the project team. Preconstruction surveys include visual inspection of the exteriors and interiors of buildings by means of video, photographs, a level survey giving elevations of basements and ground floor. 

If your property is impacted, building owners should already have received a notice from the City, and another is forthcoming from Barletta. 

All inspections will be performed in the presence of the Engineer and property owner or their designee.

Tree Removals

Updated 4/27/2018

Upcoming Construction Schedule 

Beginning the week of April 30 and continuing over the next several weeks, contractors will begin digging test pits intermittently along Somerville Ave. between Bow St. and Prospect St. Test pits are a common construction practice. Prior to the start of any excavation, construction crews dig small “test pits” to be sure that the underground infrastructure and utilities are in proper order and that the construction plan can proceed accordingly. Typically, test pits are only several feet wide and do not involve significant work or impacts to abutters, however this work will require some lane shifts, closures, and parking restrictions at Bow St., Stone Ave., and the Union Square Plaza, between 7 a.m. and 3 p.m. No parking signs will be posted along the north side of Somerville Ave., in the vicinity of 59 Somerville Ave. Please review any posted signage when parking in this area as signage and timing may change.

Preconstruction Surveys

Over the next few weeks, contractors will be contacting property owners in specific areas to conduct pre-construction property surveys. The purpose of pre-construction surveys is to document existing property conditions prior to construction. While not required, the surveys provide important documentation should property owners notice damage to their property during or after construction. Without proper documentation of conditions before construction, it may be difficult to demonstrate how or if damage may have been done to a particular property as a result of the project. Impacted properties will be notified directly by the project team. 

Preconstruction surveys of selected buildings may begin the week of May 14 or May 21. These include visual inspection of the exteriors and interiors of buildings by means of video, photographs, a level survey giving elevations of basements and ground floor. 

The City will first provide a general notice describing the project and the need to obtain access to the buildings. The Contractor will then contact individual building owners at least 2 weeks after the City has provided notice.

The Contractor will make contact by phone call to discuss need to inspect and get signed right of entry.  If they do not reach building owner by phone, then the Contractor typically sends a letter by certified mailed. 

All inspections will be performed in the presence of the Engineer and property owner or their designee.  

Tree Removal Hearings

There are 37 trees scheduled for removal as defined in the project plans. The City of Somerville held two public tree hearings in Spring 2018 to discuss these removals: March 28 and May 2. You can view the presentation slides by clicking here.

Improvements Above and Below Ground

The Somerville Ave. Utility and Streetscape Improvements project will begin in approximately April 2018, and will include the section of Somerville Ave. between Bow St/Washington St. (the heart of Union Square) and Medford St. (just past the Target). Note: this project is separate from the recent traffic improvements on Prospect St. and Webster Ave., and builds upon the Somerville Ave. Reconstruction project that was completed in 2010.)

This project will address legacy stormwater flooding issues in Union Square, and includes significant streetscape improvements. The entire project is anticipated to take approximately 3.5 years to complete.*

There are two major categories of work of the project: Upgrades to the underground stormwater management system and other aspects of the water and sewer systems, and enhancements to the overall streetscape.

  • Underground, the stormwater upgrades will increase capacity and reduce flooding with the installation of a 14-foot wide by 6-foot tall box culvert (a rectangular concrete structure) under Somerville Ave. from Union Square to Medford St. The 800,000 gallon box culvert will remove storm flows from the 100-year old, 72-inch brick combined sewer underneath Somerville Ave., eventually allowing this pipe to serve as a dedicated sanitary line. Water main replacements and sewer pipe lining rehabilitation will provide reliable service for many years to come.
  • Above ground, streetscape improvements will include enhanced pedestrian, transit rider, cyclist, and traffic facilities; and green stormwater infrastructure.
  • The enhanced facilities will reduce intersection crossing distances and improve sight lines between pedestrians, drivers, and cyclists. 6.5-foot wide bike lanes along either side of the street will be fully separated from the road by a raised curb and offset by a few feet.
  • Green stormwater infrastructure will be used to collect and filter runoff from 25% of the project area. This will be accomplished by new planted areas, stormwater infrastructure that will support large tree growth, and permeable surfaces on the bike paths and in some buffer areas. New permeable areas will lead to a reduction of 0.7 acres of impervious hard surface.

There will also be utility work by Eversource in the Union Square plaza, in the heart of Union Square near the intersection of Bow St. and Somerville Ave., and on Prospect St. The utility work is anticipated to start in March 2018. Plans showing the approximate location of this work can be found in the Plans section of the website, below.

* Project timeline may be impacted by unforeseen challenges such as inclement / severe weather, conditions of underground infrastructure, and emergencies.
