Environmental Services continues construction of the Montavilla North Sewer Repair Project in the Montavilla Neighborhood (north of Stark Street). The project includes replacing or repairing more than three miles of deteriorating 100-year-old public sewer pipes, 87 manholes, and public sewer connections for 221 properties. These improvements will help protect the public and our environment by reducing the possibility of sewage releases to homes, businesses, and streets.
The map below indicates pipe work locations and provides a construction update for the project.
Construction is expected to continue through December 2019.
In general, work hours are from 7 a.m. to 6 p.m., Monday through Friday, and Saturdays as needed.
To reduce traffic impacts, the Portland Noise Office granted Environmental Services a noise variance to work at night in NE Halsey Street at NE 71st Avenue. This location will include one or two nights of work, moved up to April 18.
Between this week and May 3, the contractor is scheduled to work at several locations. The schedule may change due to a variety of factors, including weather, conditions underground, availability of materials and labor, and other factors.
Several streets where crews had to dig into the street to repair public sewer pipes now have temporary asphalt patches.The contractor is completing final pavement restoration as weather permits. Paving is scheduled at the following locations:
The concrete pours originally scheduled for April 16 at the locations below have been postponed due to weather. When crews see an opening in the forecast, they will pour the concrete, let it cure, and then return to add a four-inch layer of asphalt on top of the concrete and level it off. That will complete the pavement restoration:
Open trench excavation and one pipe bursting to repair public sewer pipes and service laterals to adjacent properties are scheduled to occur at the following locations:
Cured-in-place-pipe lining (CIPP) to repair mainline public sewer pipes begins the week of April 17:
For all CIPP locations, see the construction methods map (click here). The work is weather-dependent. Because these pipes carry both sewage and stormwater, crews must complete the lining when there is no stormwater runoff flowing through the pipes.
Pre-construction activities may occur throughout the project area to prepare locations for construction at a future date. These activities may include inspecting and cleaning sewer pipes, marking underground utilities, tree trimming, installing tree protection, installing erosion control measures, staging equipment and materials, and setting up traffic controls.

The contractor will use a variety of construction methods to replace and repair public sewer pipes in this project. Methods include open trench excavation, cured-in-place-pipe lining, and pipe bursting. For details and photos about each method, click here.

Residents have inquired about the orange fencing around the trees on their street. This is tree protection fencing put in place before tree trimming and construction activities occur on the street. Its purpose is to protect the tree from damage due to large construction equipment on the street and construction activities in the planting strip, at the curb, and in the street. This fencing may remain in place for a few to several weeks, depending on many factors, including tree trimming subcontractor schedules, certified arborist schedules, construction schedules, and seasonal restrictions for when certain types of trees should be trimmed.
To make room for large equipment, reduce the possibility of damage to trees, and help ensure public safety, crews will trim street trees within the project area. Arborists may also trim low lying limbs on privately owned trees if they are encroaching into the public right-of-way. To accommodate the construction equipment required to perform trench excavation, trees are generally trimmed to 15 feet at each curbside and 20 feet in the center of the street.
The city only removes limbs that could be damaged or cause unsafe working conditions in construction areas. If it is necessary to remove a limb on the street side of a tree, the arborist may also direct the removal of an adjacent limb on the sidewalk side of the tree to maintain balance in the tree canopy and protect the health of the tree.
