Taggart Sewer Outfall Repair

Updated February 28, 2017

Schedule

Safety requires that crews will only be able to work in the Outfall pipes on days when there will be no flow from either rain or other parts of the sewer system. Therefore, construction may require nighttime work or two consecutive seasons - the summer of 2018 and the summer of 2019.

Between now and the start of construction, engineers will perform field surveys of the manhole access areas (see map below for updated locations). The measurements they take should not have any adverse effects on traffic.

Once construction begins, crews will most likely work Monday through Friday between 7 a.m. and 6 p.m. and Saturdays as needed, unless nighttime work is necessary and approved by the Portland Noise Office. The city will provide public notice if nighttime work will be necessary.

Sewer Repair Plan

Environmental Services has conducted a thorough study of the 110-year-old brick Taggart Outfall sewer. Engineers have determined its condition, needed repairs, and best access points along the sewer line for future construction with the fewest possible impacts to the surrounding community. The project team is currently finalizing plans for how best to repair about 3,700 feet of the Taggart Outfall sewer line so that it can operate for another hundred years.

Based on information collected about the condition of the Outfall, the project team has selected repair technologies that can be completed from inside the sewer line and will require minimal work aboveground in the roadway.

The project work zones will be located at manholes (see map below) and will move as the project segments are completed. Work at each manhole west of the MAX light rail tracks may last several months, while work on manholes in SE 16th Avenue and in SE Tibbetts Street should be less than a month at each locations. Crews may be working at multiple locations at the same time.

Note that the manhole on SE 16th Avenue at SE Rhine Street has been removed from the project. It is not needed as an access point to repair the sewer.

Possible Traffic Impacts

Accessing the sewer line through manholes will require lane closures, which will require traffic control and construction signage. When lanes are closed in a work zone, they will be closed 24/7 for the duration of construction in that area, including at night and on weekends. Where needed, traffic will be routed around the work zones.

The seven manhole access locations (see map) will have adjacent staging areas for materials and construction vehicles. 

  • Traffic restrictions along SE 10th Avenue from SE Gideon to SE Woodward
  • Pedestrian and cycling detours near the "Clinton Triangle" - along SE Gideon between SE 13th-16th
  • Minor traffic restrictions for a day or two at Se Milwaukie and SE Woodward
  • Traffic restrictions for short periods of time near SE 1th and SE Pershing, SE 16th and SE Center, and SE Tibbetts and SE 19th. 

For More Information

Prior to any construction, project staff will work closely with adjacent businesses and residents to discuss impacts and identify strategies to minimize disruptions to those who live, work or travel in the area.
