NW Westover Road Sewer Repairs

Sewer and Stormwater
Active
Environmental Services will begin construction in September on a project to construct almost 1,600 feet of public sewer improvements in NW Westover Road, NW Summit Avenue, and NW Lovejoy Street. This project will reduce risks of basement sewer backups and street flooding.
Construction is anticipated to begin in September and take up to a year to complete.

Work will include repairing or replacing 100-year-old public sewer pipes, and constructing sewer service laterals, maintenance holes, sewer cleanouts, and storm drain inlets.

Project Area

This project includes public sewer repairs in NW Westover Road, NW Summit Avenue, and NW Lovejoy Street.

Schedule

This project has experienced several delays due to the processes to obtain permanent and temporary construction easements on private properties and to finalize construction contract agreements. The City now anticipates construction to begin in September, with pre-construction activities occurring in late August and early September. 

The project will take up to a year to complete, with work at each location lasting a few to several weeks. There will be periods of inactivity between phases of construction at each location. Pavement restoration will occur after all work is completed and passes inspections. 

What's Happening Now

We anticipate the City granting the contractor a notice to proceed with construction later this month. You may then see crews in the neighborhood preparing for sewer construction. These pre-construction activities typically occur over time rather than all at once:   

  • Inspect sewer pipes and maintenance access holes.
  • Locate underground utilities and mark them with paint or small flags.
  • Survey the land and take various measurements.
  • Drill holes in the street to collect soil and pavement samples.
  • Determine if trees will need construction protections and put them in place.
  • Coordinate with the Portland Bureau of Transportation to develop traffic control plans and anticipate pavement restoration requirements.
  • Take photos to document existing conditions. 

Looking Ahead

The sequence of work for sewer improvements at each location is not known at this time. We anticipate that crews will begin in NW Lovejoy Street at SW Cornell Road with the installation of a large maintenance hole, followed by the installation of new public sewer pipes to the end of NW Lovejoy. The work in NW Lovejoy could take several weeks. That plan is dependent upon contractor coordination with their subcontractors on the schedule and the availability of labor and materials. 

We then anticipate that crews will move to NW Summit Avenue and finally to NW Westover Road. We hope to have a general schedule from the contractor in late August, at which time we will provide another public notice with the anticipated timeline for each location. 

What to Expect During Construction

To establish a safe work zone, it will be necessary to restrict use of NW Westover Road, NW Summit Avenue, and NW Lovejoy Street periodically during construction:

  • Temporary road closures, lane restrictions, crosswalk closures, and detours will be in place as needed. 
  • Local access to businesses and residents will be provided, but through traffic will be restricted. Please observe traffic control signs, follow signed detours, and share the road safely.

On-Street Parking

The contractor will post NO PARKING signs on streets where crews will be working and staging equipment and materials. Please plan to move your vehicles off the street by 7 a.m. and return them at 6 p.m. on days when crews are working. Keeping your vehicles parked on the street puts them at risk of being towed, delays the work, and extends the inconvenience to you and your neighbors. 

The following on-street parking restrictions apply:

  • Residents may NOT park in any space signed NO PARKING during the hours of 7 a.m. to 6 p.m. on days when crews are working.
  • Residents may park in any space signed NO PARKING during the hours of 6 p.m. to 7 a.m. on days when crews are working.
  • Residents may park in any space signed NO PARKING during all hours when crews are NOT working.

Construction Methods

Crews will use a combination of Open Trench Excavation and a trenchless method called Cured-in-Place-Pipe Lining (CIPP) to construct the sewer improvements in this project. Below is a description of the work to occur at each location and the construction methods to be used.  

  • NW Lovejoy at NW Cornell: Crews will repair one sewer pipe segment, or 45 feet, using Cured-in-Place-Pipe (CIPP) lining. The lining will seal cracks and help prevent root intrusion. Crews will also construct maintenance holes and storm drain inlet leads.
  • NW Lovejoy between NW Marcia and NW Cornell: Crews will abandon old clay sewer pipes that run behind the curb and near trees. They will replace the clay pipes with 216 feet of reinforced concrete pipe using Open Trench Excavation. Crews will also construct maintenance holes, storm drain inlet leads, and service laterals.
  • NW Lovejoy between NW Summit and NW Marcia: Crews will abandon old clay sewer pipes that run under stairs, behind the curb, and near trees. They will replace the clay pipes with 192 feet of reinforced concrete pipe using Open Trench Excavation. Crews will also repair two pipe segments, or 221 feet, underneath the stairway using Cured-in-Place-Pipe (CIPP) lining. Because no digging will occur near the stairway, it will remain open, with short-term closures as needed to perform the work safely. The lining will seal cracks and help prevent root intrusion. Crews will also construct maintenance holes, storm drain inlet leads, and service laterals.
  • NW Summit between NW Westover and NW Lovejoy: Crews will replace 393 feet of old clay sewer pipes with upsized, reinforced concrete pipe using Open Trench Excavation. Crews will also construct sewer cleanouts, maintenance holes, storm drain inlet leads, and service laterals.
  • NW Westover west of the intersection with NW Summit: Crews will replace 490 feet of old clay sewer pipes with upsized, reinforced concrete pipe using Open Trench Excavation. Crews will also construct maintenance holes, storm drain inlet leads, and service laterals. The existing speed bump will be removed for sewer construction and replaced after sewer construction is completed.

Open Trench Excavation is the traditional method of sewer construction and the most common method for installing a new sewer pipe. It consists of digging down to the required depth, installing a new pipe, and then backfilling the trench.

CIPP involves inserting a flexible liner inside the existing pipe, inflating the liner, and exposing it to heat or ultraviolet light to dry and harden the liner inside the pipe. The liner essentially forms a smooth surface inside the existing pipe, restoring it to near-new condition.

Pavement restoration will occur after all work is completed and passes inspections.

Project Background

Environmental Services completed two urgent sewer repairs in this area in 2020. Issues and investigations associated with those repairs led to this new and larger project to make public sewer improvements in NW Westover Road, NW Summit Avenue, and NW Lovejoy Street.

The prior urgent sewer repairs were as follows:

  • Urgent Pipe Repair Between NW Westover and NW Summit—In January of 2020, crews completed an urgent public sewer repair that was located in private property between NW Westover Road and NW Summit Avenue.  
  • Small Pipe Repair in NW Westover—In late October of 2020, crews repaired a small, 50-foot section of sewer pipe located in NW Westover Road.  

The new project scheduled to begin construction in January of 2022 will increase capacity of the mainline public sewer and reduce the risks of basement sewer backups and street flooding in the area. 

We Want to Hear from You

Environmental Services will inform residents and businesses about project activities and respond to questions and concerns in a timely manner. We encourage you to:
