The Port Infrastructure Improvements Project

Notice: Essex St. Closure

Beginning approximately Monday, October 1, 2018, the City’s contractor for the Port Infrastructure Project, Skanska Civil USA, will be performing water main relocation work at the intersection of Essex Street and Bishop Allen Drive.   Given the size of the work zone needed, vehicular access to Essex Street from Bishop Allen Drive will need to be blocked during much of this work.  This work is expected to be completed within 2-3 weeks.   
 
Within this time frame, during general working hours, you may not have vehicular access to Essex Street from Bishop Allen Drive.  Normal street access is expected to resume at the completion of every construction work day. 

What to expect during construction: 

  • General work hours will be from 7AM to 4PM, Monday through Friday.
  • Abutter vehicles will be able to enter Essex Street “wrong way” from Harvard Street, under the supervision of a Police Detail officer stationed at the Harvard/Essex Street intersection.  Due to the narrow width of the street, we ask that vehicle trips be reduced to a minimum, and that drivers exercise caution and patience. 
  • “No Parking” signs, if needed to facilitate the work or traffic flow, will be posted at least 24 hours in advance of construction. Please be sure to check posted signs for exact dates and times.  
  • There may be some exploratory work starting during the week of September 24th, 2018, but this work will not prevent vehicular access to Essex Street from Bishop Allen Drive. 
For Information and Assistance During Construction If you have any questions about the construction work or need assistance, including if you have any special needs or disabilities that require special accommodations, please contact Kate Riley, DPW Community Relations Manager at (617) 349-4870 or kriley@cambridgema./gov.  More information about the project in general can be found at www.cambridgema.gov/theworks/theport.

Notice: The Port - PL 6 Stormwater Tank Project - Upcoming Construction on Massachusetts Avenue

The City of Cambridge has awarded a contract to the firm of Skanska USA Civil for the construction of the first phase of The Port Infrastructure Improvements Project. This first phase, known as the “PL6 Stormwater Tank Project”, includes the construction of an underground 390,000 gallon storage tank and pump station, which will be located beneath a portion of the City’s Parking Lot 6 on Bishop Allen Drive.

In addition to the tank and pump station, the PL6 Project includes construction of a utility tunnel beneath the MBTA Red Line to connect the tank to the existing Mass. Ave. storm drain. This work, along with associated utility relocations and surface restoration, will require construction work in Massachusetts Avenue between Douglass and Sidney Streets, for a period of approximately 15 months, beginning in mid-August 2018.

WHAT TO EXPECT ALONG MASSACHUSETTS AVENUE (NOTE - ALL SCHEDULE DATES ARE APPROXIMATE, AND THE CITY WILL ISSUE PERIODIC UPDATES AS MORE DETAILED TIME FRAMES BECOME KNOWN):
  • Mid-August 2018: Excavation of test pits at several locations between Douglass Street and Lafayette Square to verify existing utilities. 
  • Mid-September 2018: Establishment of a long-term work zone on the north side of Mass. Ave. along Lafayette Square (across from the Salvation Army building) and extending west along the Mass+Main frontage. This will allow for utility relocations and the major work of constructing the utility tunnel and its access shafts. The City will provide additional details (including maps) about this aspect of the project later this summer, but in general:
- The work zone will be in place from mid-September 2018 until August 2019.

- Approximately 8-10 parking and loading spaces on the north side, beginning at Lafayette Square and heading west, will be temporarily eliminated.

- A portion of Jill Brown-Rhone Park at Lafayette Square, primarily the open plaza area across from the Salvation Army building, will not be accessible during this time.

- The crosswalk at 424 Mass. Ave (Mariposa Bakery) will be eliminated for much of this time.

- Mass. Ave. will be reduced to one vehicle lane in each direction, plus one bicycle lane in each direction, from approximately 450 Mass. Ave. (La Fabrica) to Sidney Street.

- We are coordinating closely with the Mass+Main project, so that Mass+Main can do its own required utility work on Mass. Ave. during this same timeframe, avoiding multiple shutdowns.

  • Mid to late October 2018: Excavation across Mass Ave just east of McDonalds, to replace an obsolete water main. This work will be performed in stages to accommodate traffic at this location. 
  • Late October - mid-December 2018: Reconstruction of a major drainage structure located in the sidewalk in front of 485 Mass. Ave. (Peoples United Bank). This work also requires relocation of water, electric, and telephone conduits at this location. 
  • August 2019 - November 2019: Construction of a new section of sanitary sewer in the north side of Mass. Ave. from Lafayette Square to Sidney Street, and across Mass. Ave. into Sidney Street. Repaving of the portions of Mass. Ave. which have been disturbed during the project, and restoration of full pedestrian, bicycle, and vehicular access. 

GENERAL INFORMATION:
  • Work hours will be 7 AM to 4 PM, Monday through Friday. Evening and weekend work is not planned but is possible. Abutters will be notified in advance.
  • There will be noise and disruption from construction activities.

  • The City has awarded a contract to the firm of Skanska USA Civil for the construction of the first phase of the project. This first phase, known as the “PL6 Stormwater Tank Project”, includes the construction of an underground 390,000 gallon storage tank and pump station, which will be located beneath a portion of the City’s Parking Lot 6 on Bishop Allen Drive. Stormwater runoff from The Port neighborhood will be stored in this tank, and subsequently will be pumped out into a large storm drain located in Massachusetts Avenue. 
  • In addition to the tank and pump station, the PL6 Project includes the construction of a utility pipe tunnel beneath the MBTA Red Line tunnel, which will allow for the connection of the tank to the Mass. Ave storm drain. The project also includes associated utility relocations and improvements in Bishop Allen Drive between Columbia and Essex Streets; and in Massachusetts Avenue between Douglass and Sidney Streets. 
  • At the completion of the project in mid-2020, the impacted portion of Bishop Allen Drive, including the roadway and sidewalks, will be reconstructed.
  • The City project will be performed in close coordination with the private Mass+Main project, which is also located in the Parking 6 area. At the conclusion of both projects in mid-2020, the Mass+Main project will completely reconstruct Parking Lot 6 to the City’s requirements, and it will again be available for public parking. In the meantime, the temporary Parking Lot 6 at 65 Bishop Allen Drive will continue to be available to the public. 
  • Additional community engagement about the PL6 Project, and the overall Port Infrastructure Project, will continue in the late summer/early fall of 2018.

Learn about Flow...A Grant Program for the Port from Cambridge Arts.
Many neighborhoods in the Cambridge area are susceptible to the impacts of flooding. Particularly at risk are those properties with basement spaces and first levels at a lower elevation. The City’s assessment on climate change vulnerability has shown the risk of flooding is increasing over time, as the impacts of climate change lead to more frequent and intense rainfall events.

The Port has experienced significant flooding in the past. The City is focusing on this area in the coming years via The Port Project to improve these conditions.

While change remains an inevitable process, infrastructure projects like these will decrease future flooding risks.

PRE-CONSTRUCTION ACTIVITY NOTICE

Over the next five years, the City anticipates spending over $35M for the design and construction of water, sewer, drainage, street and sidewalk improvements in your neighborhood. The improvements will focus on rehabilitating existing infrastructure, constructing two underground stormwater tanks, reducing flooding in the area, and reconstructing the streets and sidewalks. The locations of these improvements are (see map):

  • Streets and Sidewalks: Bishop Allen Drive (Prospect to Main), Cherry Street (Main to Harvard), Columbia Street (Main to Washington), Eaton Street (Pine to Cherry), Pine Street (School to Harvard), and Washington Street (Norfolk to Windsor)
  • Stormwater Tanks: Parking Lot 6 on Bishop Allen Drive and Clement Morgan Park on Columbia Street

While the formal design and community process for this project will not begin until the winter months of 2015, pre-construction activities are scheduled to begin the week of October 12th in your neighborhood and we wanted you to be aware of this activity. These activities include:

  • Data collection: The City’s consultant engineers, Kleinfelder, MWH and WSP, along with their sub-consultants, will begin to collect the data needed to complete the design of this project - including topographic surveys, cleaning and inspection of pipes and structures, and soil borings. Soil borings will be conducted in public streets and sidewalks and should have little impact on the community. They will also be performing building inspections, to verify the number and location of utility connections. Owners will be sent a separate notice with details on how to schedule inspections at their property, if required.
  • Questionnaire: In the months ahead, you will be receiving a questionnaire that we encourage you to fill out and return to us. As a resident, your knowledge of this neighborhood is valuable and will help us to inform and improve the final project design, which will directly benefit you and your neighborhood.
