Arbor Lodge–Kenton Sewer Project

Construction type
Sewer and Stormwater
Project status

Environmental Services is constructing a project in the Arbor Lodge-Kenton Neighborhood area to repair over two miles of public sewer pipe. Having provided over 85 years of service on average, the pipes require repairs to maintain reliable sewer service and protect public health and the environment.

Construction began in August 2020 and the entire project will take about a year and a half to complete.

Project Area

This project will construct sewer improvements in multiple locations within the Arbor Lodge, Kenton, and Portsmouth neighborhoods. The map below illustrates where construction will occur, and which construction method will be used at each location.  The map also indicates where evening and overnight construction are expected.

What's Happening Now

Work will occur in phases at each location in the project area often with periods of inactivity between each phase. Depending on the location and construction method, work could last a few weeks to a few months in one area. Below is a two-week look ahead of construction activities: 

Week of March 8

Crews will install sewer cleanouts using a trenchless system over the next two weeks at the following locations:  

  • N Greeley Avenue south of N Buffalo Street
  • N Greeley Avenue between N Rosa Parks Way and N Holman Street
  • N Rosa Parks Way between N Fenwick Avenue and N Concord Avenue

Week of March 15

N Fowler Avenue north of N Willamette Boulevard:

  • Crews will repair the sewer mainline and reconstruct a couple of lateral sewer connections using open trench construction. This will take about 4 days to complete.

Crews will install sewer cleanouts using a trenchless system over the next two weeks at the following locations:

  • N Peninsular Avenue between N Hunt Street and N Houghton Street
  • N Baldwin Street east of N Washburne Avenue
  • N Greeley Avenue south of N Bryant Street
  • N Greeley Avenue north of N Dekum Street
  • N Greeley Avenue north of N Rosa Parks Way


The pipe lining process involves inserting a flexible liner inside the old pipe, inflating the liner, and exposing it to heat or ultraviolet light to "cure" and harden the liner inside the pipe.

You may smell an odor like plastic or glue during CIPP that will dissipate quickly once the process is complete. The odor is from chemicals in the liner resin. The amounts detected by an independent industrial hygienist are below health risk levels.

To keep the resin odors from entering your home or business through your private sewer, fill any floor drains and infrequently used sinks with a small amount of water. This water will collect in the bend in the drain and block odors from the sewer.


A sewer cleanout is a capped opening above the sewer service lateral that connects a property or a building to the mainline public sewer. It provides access for future maintenance to enable crews to clean and repair that connection. Cleanouts may also be used to maintain sewer service during a mainline pipe lining process or to provide ventilation during that process.

Cleanouts are typically installed near the curb but may also be placed in the planting strip between the curb and the sidewalk, in the sidewalk near a property or building, or on private property above the sewer lateral.

Sewer cleanout installation requires digging a small-diameter hole where the cleanout will be located. Crews dig down to the service lateral, cut into the service lateral, connect a standing pipe to the surface, and add a cap at ground level. 

We Want to Hear from You

Also, please write “ALK” in the subject line of your email.  

Sewer Emergency: In the event of a sewer backup or basement flooding, call the Maintenance hotline immediately at 503-823-1700. It is staffed all hours and all days, 24/7.  

Construction Methods

The contractor will use several construction methods to complete sewer and stormwater improvements. Some will require digging trenches. Others will replace pipes through manholes or access pits to reduce surface disruption. 

  • Open Trench Excavation: The contractor excavates a trench, installs a new pipe, fills in the trench and restores the disturbed pavement. 

  • Cured-in-Place-Pipe Lining (CIPP): Through a manhole, the contractor inserts a flexible liner into the old pipe. The liner hardens, creating a new interior lining. You may smell an odor like plastic or glue during this process from the liner resin. 

  • Pipe Bursting : The contractor pushes a bursting head into the sewer line to break apart the old pipe while pulling a new pipe into place behind it. 

See the map above for the construction method at each location. 

What to Expect

You can expect the following activities and impacts during construction: 

A Safe Work Site: We want you to be safe around the work site. Please keep children, pets, bikes, cars, and trucks away from the tools, machines, supplies, and construction workers. 

Noise, Vibration, and Dust: Construction creates noise, vibration, and dust and disrupts normal neighborhood activity. 

Traffic Delays: The work will slow down traffic in your neighborhood. Please read the traffic signs and follow directions from the workers with flags. 

Access to Your Home or Business: You will be able to go to your home or business, but you may not be able to park as close as you would like. We will try to make sure driveways and parking lot entrances stay open. Crew members can help you safely enter or exit your driveway or business parking lot.   

Parking Restrictions: We want you to be safe, so you might not be able to park your car next to work spaces, equipment, or materials. If crews are working directly in front of your home or a business, you may need to park in another place. 

Equipment Storage: Sometimes we will leave tools, machines, and supplies on your street overnight.  

Maintained Service: You can still use sewer, water, and other services while we work on your street. 

Work Hours: Work hours are 7 a.m. to 6 p.m., Monday through Friday. Sometimes we work on Saturdays from 7 a.m. to 6 p.m. 

Schedule Changes and Inactivity: Work schedules can change for many reasons like weather, traffic, and problems with tools, machines, or supplies. Sometimes we need to stop between different types of work and start again later.
