Montavilla North Sewer Repair

Updated September 9, 2019Button. Click to sign up for email updates

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.

For information about the sewer improvements in the Hollywood-Grant Park neighborhoods that are included in this project, visit www.portlandoregon.gov/bes/HGP2.

General Schedule

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.

Look-Ahead Schedule

During the week of September 9, 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. See below for the types of activity and locations.

Pre- and Post-construction Video Inspections
On September 10, crews will conduct pre-construction video inspections of public sewer pipes at the following locations:

  • NE 75th Ave north of E Burnside St – Video inspection September 10
  • NE Pacific St east of NE 82nd Ave – Video inspection September 10

Before crews complete sewer repairs at these locations, they will run water through the pipes to clear them of debris. Crews will then insert a video camera into the pipes to document their condition and locate connections to adjacent properties. The pre-construction inspections will help verify and prepare for appropriate construction methods at each location.

Also, on September 10, crews will conduct post-construction video inspections of public sewer pipes at the following location:

  • NE Holladay St east and west of NE 84th Ave – Video inspection September 10

The post-construction inspections will help verify that the work was done properly and no additional repairs are necessary.

To complete these video inspections, crews typically park trucks and equipment near manholes. The work can cause minor traffic disruptions and typically lasts only a few hours or one day at each location.

Miscellaneous Concrete Work
When crews see an opening in the forecast, they will do a variety of concrete work at various locations throughout the project area. This may include manhole repairs, curb and sidewalk restoration, and concrete pavement restoration. We cannot provide a schedule of specific dates and locations for this work, because crews may be able to work at multiple locations in one day, depending on the scope and complexity of the repairs.

Pre-construction Activities

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. Click here for more information about pre-construction activities.  

Construction Methods

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.
