Kenton Sewer Project Will Begin Construction Soon
Environmental Services will begin construction within a few weeks on the Kenton Sewer Repair Project. This project will replace about 7,000 feet of public sewer pipes that are between 80 and 90 years old and failing due to age. The work will include repairing or replacing about 2,500 feet of existing service laterals that connect houses and businesses from the curb to the public sewer in the street. This project will increase sewer capacity and reduce the risks of street flooding and sewage releases to homes, businesses and streets.
The city will use a combination of open trench construction, cured-in-place-pipe lining, and pipe bursting. Details about each construction method are available at www.portlandoregon.gov/bes/64780.
Construction is scheduled to begin within a few weeks and may take up to 14 months to complete. You may see city staff or contractors surveying, marking and moving utility lines, and trimming trees to prepare for the start of construction. 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 at several approved locations.
NIGHT WORK AT SEVERAL LOCATIONS
The Portland Noise Control Office granted Environmental Services a noise variance for nighttime construction at several locations in this project (see map at www.portlandoregon.gov/bes/kenton).
A city inspector will be on-site during this night work. To report concerns during night work, please call the on-site hotline at 503-823-8458. You may also call the Portland Noise Control Office at 503-823-7350 or email firstname.lastname@example.org.
N INTERSTATE AVENUE AND N RUSSET STREET
Construction in the intersection of N Interstate Avenue and N Russet Street will occur from 10:00 p.m. to 6:00 a.m. Monday through Saturday and should take no more than five days to complete. Businesses and residents in the construction area will be notified in advance of this night work.
The city’s contractor will excavate a trench to replace the public sewer pipe. The contractor will use heavy equipment to excavate and restore the pavement, and temporary lighting for the work area at night. The southbound travel lane of N Interstate Avenue will be closed and traffic re-routed during construction hours.
CURED-IN-PLACE PIPE LINING LOCATIONS
The contractor will use cured-in-place pipe lining (CIPP) to repair several sewers. Work crews may install lining at night at some locations because of the size of the pipe. Work at each location should take no more than a few days. People who live and work near a CIPP repair project can sometimes smell a chemical odor during pipe-lining. The odor is from the chemical styrene, which is in the resin liner installed inside the pipe. The odor dissipates quickly once the installation process is complete. The amount of airborne styrene the repair process produces is not a human health risk. More details about CIPP are available at www.portlandoregon.gov/bes/64780.
WHAT TO EXPECT DURING CONSTRUCTION
- Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
- 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.
- 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.

Working for clean rivers
Over one-third of Portland's 2,500 miles of sewer pipes are more than 80 years old. Projects to replace or repair aging sewers are important for protecting water quality, public health and the environment. Learn more at www.portlandoregon.gov/bes.
