SE 3rd Avenue Sewer Project Construction Update: September 1, 2021

The Water Bureau continues to relocate a water mainline on SE 3rd Avenue, south of SE Belmont Avenue until September 17.

Sewer construction will begin September 20 and is expected to last about five months.

Construction work hours are 7 a.m. to 6 p.m., Monday through Friday, and Saturdays if needed.



Due to the very soft soil conditions in the area, the contractor will be using the Jack and Bore method of sewer construction. Jack and Bore is a trenchless construction method that involves drilling a hole underground and pushing a new pipe in to place.  To learn more about the Jack and Bore method of construction, visit


You can expect the following activities and impacts with this sewer repair project:

  • Safe 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: Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
  • Traffic Delays: You should expect traffic delays in and near the work area. Please observe traffic control signs and follow the directions of flaggers. The contractor will maintain local access to all properties, but construction may impact normal use of your driveway or entrance to your business
  • 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 will be stored on your street or nearby streets overnight.
  • Maintained Service: Sewer, water, and other utilities will remain in service during construction.
  • Typical Work Hours: 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: Construction schedules can change due to a variety of factors, including conditions underground, weather, traffic impacts, subcontractor schedules and availability of materials. These same variables may cause periods of inactivity during construction phases.
