NE 20th and Tillamook Sewer Project

Updated December 02, 2019

Environmental Services, the city’s sewer and stormwater utility, has finished construction to replace the main sewer pipe in NE 20th Ave between NE Tillamook and NE Thompson streets. The project included repairing approximately 500 feet of deteriorating 128-years-old public sewer pipe, repairing 12 lateral service connections, which connect private properties to the new public sewer, and installing three manholes. These improvements will increase capacity and protect water quality, public health, and the environment by reducing the possibility of sewage releases to buildings and streets.

Construction was completed in late November 2019.

NE 20th and Tillamook Sewer Repair Project


Construction has been completed.

Pre-Construction Activities

Pre-construction activities may occur throughout the project area to prepare for the upcoming sewer repair work. These activities marking underground utilities, tree trimming, installing tree protection, installing erosion control measures, staging equipment and materials, and setting up traffic controls. More details along with photos of these activities are available online at

Construction Methods

Environmental Services will use an open trench excavation method for the sewer work on this project. Open trench excavation is the traditional and most common method of sewer construction, repair or replacement. Open trench excavation consists of excavating down to and exposing the existing pipe so that it can be repaired or replaced. Learn more about this construction method at

Private Improvements in the Right-of-Way

The space between the sidewalk and curb next to your property, also known as the planting strip, is public right-of-way and the contractor may discard items that are in the planting strip when construction begins. Please remove items in the right-of-way that you would like to keep before construction begins.

What to Expect During Construction

  • Work Site Safety is our top priority for every construction site. You can help keep the area safe by staying clear of all construction activities and keeping children, pets and vehicles out of construction areas.
  • Noise, Vibration, and Dust from construction may disrupt normal neighborhood activity.
  • Traffic Delays should be expected in and near the work area. Please observe traffic control signs and follow the directions of flaggers.
  • Local access to all properties will be maintained, but construction may impact normal use of your driveway.
  • 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 will be stored on your street or nearby streets overnight.
  • Sewer, water, and other utilities will remain in service during construction.
  • Typical Work Hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.
  • Schedule Changes and Inactivity during construction phases can occur due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials.
