Updated July 22, 2019

Environmental Services continues construction on a sewer repair project in the King neighborhood to repair or replace approximately 700 feet of public sewer on NE 12th and 13th avenues between Humboldt and Wygant streets. The project will also replace 27 public lateral connections from the sewer mainline to the curb. These pipes are almost 100 years old, and are deteriorating due to age. This project will reduce the possibility of costly breaks and sewage releases to homes, businesses, and streets.


Construction began in late May 2019 and is expected to be complete in early August 2019. All work will occur between 7:00 a.m. and 6:00 p.m., Monday through Friday, with the option of working Saturdays.

Construction Method

Open trench construction will be used to complete all work. Go to to view photos and learn more.  After sewer construction, crews will backfill trenches and apply a temporary asphalt patch. The temporary patch may be in place for several weeks while quality control inspections occur. After all work has met required standards, crews will return to apply a permanent patch.  

What to Expect During Construction

Project Map

  • Local Access: Local access to all properties will be maintained, but construction activities may impact or delay normal use of your

    driveway. Please allow for extra time for our crews to make the area safe before entering or leaving the construction area.

  • Traffic Delays: You should also expect traffic delays in and near the work area. Please observe traffic control devices and signs, and follow the directions of flaggers if present.

  • Parking Restrictions: On-street parking will be restricted in and near the work zones to create a safe work environment and to stage equipment and materials.

  • Equipment Storage: Some equipment and materials may be stored overnight on your street, nearby streets, or other public right-of-way areas.

  • Noise, Vibration, and Dust: Construction creates noise, vibration, and dust.

  • Periods of Inactivity: Work will be conducted in multiple phases. A variety of factors, including conditions underground, weather, subcontractor schedules, and availability of materials may cause periods of inactivity. 

  • Maintained Service: Water and other utilities will remain in service during construction.
