email sign up button

Environmental Services ‐ the City’s sewer and stormwater utility ‐ will begin construction soon on a public sewer project that will replace 350 feet of sewer line in NE Everett Street that is deteriorating due to age. This project will help protect public health and our environment by reducing the possibility of sewer backups and sewage releases to homes, businesses, and streets.

Map of the Davinci Sewer Project Area


The Portland Water Bureau has completed relocation of water lines in NE 26th Avenue between NE Everett Street and NE Flanders Street.

Sewer construction will begin during the week of April 8th, 2019 and will take approximately six months to complete.

Previous Activities

In January of 2018, crews completed work to abandon and decommission the old sewer line from 1908 that runs through the grounds of the Da Vinci Arts Middle School. This process installed a plug in one end of the line and then pumped grout in to the old line. This shored up the line and will prevent sinkholes or collapses in the future.

What to Expect During Construction

You can expect the following construction impacts in the area:

  • Preparation: you may see some activities in the area as work crews prepare for the project. These activities include surveying and utility locating (colorful paint on the ground), erosion control measures, and construction crew mobilization and materials staging.
  • 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.
