Kenton Sewer Repair Project

Environmental Services is replacing about 7,000 feet of public sewer pipes in the Kenton neighborhood that are between 80 and 90 years old and deteriorating due to age. This project will increase sewer capacity and reduce the risks of street flooding and sewage releases to homes, businesses and streets.


  • Most mainline repairs and replacements are complete. However, you may still see crews on your street working on spot repairs and “punch list” items over the next six weeks. Punch list items are small repairs or other minor pieces of work that need attention after the main work is completed.
  • Crews will be reseeding the field adjacent to De La Salle North High School (7528 N Fenwick Ave). Please stay off of newly seeded areas. On September 8th, the contractor will be replacing a section of fence that was taken down to give access to machines working on the sewer line under the field.


This schedule is subject to change due to a variety of factors, including underground conditions, weather, subcontractor schedules and availability of materials. As the contractor completes construction on each street, work crews apply a temporary asphalt patch. They will return at a later date to apply permanent paving.

As weather and availability of work crews and equipment allow, crews are beginning to do final paving on streets where sewer repairs are complete. Due to these variable circumstances, paving work may occur that is not part of this notice and some scheduled final paving may be delayed.

Week of August 24th:

  • Throughout project area –  crews will be doing minor repairs, spot paving and replacing a small number of private branches to connect residences to the main public sewer line. 
  • Kenton Park – Crews will begin preparation for mainline repairs along the north side of the park. Please stay away from work zones and keeps kids and pets away from any construction activities.  All pathways will remain open during construction in the park.

What to Expect during Construction

  • Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
  • Typical construction hours will be 7:00 a.m. to 6:00 p.m. Monday through Friday. If needed, the contractor may work the same hours on Saturday. The contractor will work at night to complete the cured-in-place pipe lining on larger pipes in several locations (see map). One location will require nighttime work to complete the open trench sewer repair. To minimize daytime traffic disturbance on N Interstate Avenue, sewer construction in the intersection of N Russet Street and N Interstate Avenue will require night work for no more than five days. We will notify residents in advance of night work.
  • Please stay clear of all construction activities and keep children, pets and vehicles out of construction areas.
  • On-street parking in or near the work area may be limited. Please observe no parking signs.
  • Equipment and materials may be stored on nearby streets overnight.
  • The contractor will maintain local access on streets, but you should expect delays. In some cases, construction activities may impact normal use of your driveway.
  • Sewer construction generally occurs in the street. However, in a few areas the contractor will have to cut into sidewalks and driveway edges then restore the areas. Construction may also affect the planting strip, the area between the curb and sidewalk. We will notify property owners where this may occur.
  • During construction, the city’s contractor will use by-pass pumps to maintain sewer service. If a short, temporary sewer service shut-off is necessary to relocate a line, the contractor will notify property owners in advance.
  • Construction near an individual property could last a few weeks. This may seem longer where the work extends on the same street for a block or more. Sewer construction has many phases, and there may be periods of inactivity between construction phases at each site.
  • A city inspector will be on-site during work hours and may be able to assist you with concerns. Inspectors wear a hard hat and a safety vest with “City of Portland” on the back.
