Schedule

The city's contractor, James W. Fowler Co., continues construction of public sewer repairs. The project, which began in September of 2022, will continue through the Spring of 2023, with work at each location lasting a few to several weeks.

What's Happening Now

Public sewer repairs continue in NW Westover Road. The schedule below is subject to change due to weather, materials availability, subcontractor schedules, underground conditions, unknown utility conflicts, or other factors.

Week of February 6:

  • Complete installation of maintenance hole in NW Westover Rd at 2705 NW Westover.
  • Install seven (7) sewer service laterals in NW Westover Rd between NW Summit Ave and 2705 NW Westover. A sewer service lateral is a pipe that provides a public sewer connection for a house, business, or undeveloped property. It runs from the mainline public sewer in the street to the curb and connects to the property’s private sewer line or is capped at the property line for future use, e.g., future development or resolution of a nonconforming sewer connection.

Week of February 13:

  • Install six (6) catch basin inlet leads in NW Westover Rd between NW Summit Ave and 2705 NW Westover. Catch basins and curb inlets are a key component of underground drainage systems. They prevent flooding and convey stormwater. Most catch basins consist of a below-ground box or cylinder topped with a grate. 
  • Begin work on the construction punch list—also called a deficiency list. The punch list refers to remaining action items that must be completed before a project officially ends. It lists items that have not been completed or that need to be adjusted to ensure the work passes inspections.

Week of February 20:

  • Continue work on the construction punch list. 
  • Sewer crews will insert closed-circuit television cameras into maintenance access holes to conduct post-construction inspections and determine any unresolved issues for the contractor to address.

Pavement Restoration

In sewer and stormwater construction projects where crews dig into city streets, Environmental Services is required to follow specifications set by the Portland Bureau of Transportation (PBOT), who owns the streets and manages the public rights-of-way. PBOT determines what pavement restoration a project must do and provides direction that meets the intent of the City’s Pavement Restoration Standard Drawings for Local Streets or Busy Streets.

For the NW Westover Road Sewer Repairs Project, sewer and transportation crews will walk NW Westover Road, NW Summit Avenue, and NW Lovejoy Street to determine pavement restoration requirements and area limits for new pavement. They will review where crews had to dig up the street to install new sewer pipes, maintenance access holes, and storm drain inlets and determine where and how to provide permanent restoration of the temporary asphalt patches. 

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:

  • Regular work hours will be from 7 a.m. to 6 p.m. Monday through Friday, and Saturdays as needed.
  • Temporary road closures, lane restrictions, parking 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. 
  • Sewer, water, and other utilities will remain in service during construction.
  • There may be periods of inactivity between construction phases due to a variety of factors including weather, subcontractor schedules, and availability of materials.
  • After work passes inspections, crews will re-pave sections of the street that they had to dig up to install new sewer pipes and maintenance holes.

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.
