SW Alder-Oak-Taylor Sewer Repair Project

Updated November 9, 2017Button. Click to sign up for email updates

Environmental Services is designing a project to repair about 800 feet of public sewer pipes in downtown Portland that are 100 to 140 years old and in deteriorating condition. The sewer pipes are showing signs of cracks, breaks, holes, offset pipe connections, and obstructions, putting the pipes at risk of structural failure. Urgent repairs at three locations shown on the map below will protect the public and the environment by reducing the possibility of sewage releases to buildings and streets.

Utility Locates

On Tuesday and Wednesday, November 14-15, city crews will be working in SW Oak Street between SW 1st and SW 2nd Avenues. They will conduct a simple excavation process to drill holes and remove debris from proposed construction areas to locate utilities and determine other underground conditions. What the engineers learn from this process will help them determine construction locations and methods.

What to Expect

The utility locates are scheduled to occur both days - November 14-15 - between 7 a.m. and 3 p.m.

  • On Tuesday, crews will drill five holes, about 12 inches wide and 3 feet deep, in street pavement. This work is expected to take about two hours.
  • On Wednesday, crews will vacuum out the holes and record the location and depth of utilities they find. Crews will fill the holes immediately after this work is completed. This work is expected to take about four hours.

There may be brief periods of noise, dust, and mild vibration during drilling.

Drilling to locate utilities will not be necessary at the other two locations in the project.

Traffic Impacts

On-street parking will be removed for half of the block on the north side of SW Oak Street just west of the intersection at SW 1st Avenue. The traffic lane and bike lane will remain open.

Construction Timeline

No construction in the public right-of-way (streets and sidewalks) will occur during the city's Holiday Moratorium from November 16, 2017, continuing through January 2, 2018.

Construction of sewer repairs in all three locations illustrated on the map is currently expected to occur between January and June of 2018. Keep in mind that schedules are always subject to change due to weather, equipment, subcontractor schedules, or other issues.
