SW Ventilation and Capacity Improvements Project

Due to weather and contractor schedules, there will NOT be continuous construction Friday April 24 - Monday April 27.

Environmental Services began construction in early February 2015 on a project to install about 1,000 feet of 24-inch concrete pipe along SW Taylors Ferry Road and 800 feet of 48-inch concrete pipe along SW Virginia Avenue.

The project will increase the capacity of the Southwest Parallel Interceptor sewer system to accommodate future growth, and will install a permanent odor control facility to reduce sewer odors in this area.

Developments of Note

  • Due to weather and contractor schedules, there will NOT be continuous construction Friday April 24 - Monday April 27.

  • The contractor plans to work the weekend of May 1-4 from 8:00 p.m. Friday to 6:00 a.m. Monday. The contractor will work the same continuous hours May 8-10. The weekend work is weather dependent and may be rescheduled.
  • Detours will be in place during this weekend construction to allow work crews to install 84-inch manhole.
  • Traffic will be reduced to one lane with flaggers controlling traffic. The city may close Taylors Ferry Road if construction makes vehicle passage unsafe. Please plan to use an alternate route.
  • Environmental Services and the project contractor have decided to reduce the size of the manholes installed for this project. This will reduce traffic impacts and the time it will take to complete the project.
  • Work is weather dependent. Bypass pumps move sewage around the section of pipe under construction. When it rains, stormwater runoff can increase flow beyond the capacity of bypass pumps, which can postpone construction.
  • Vibrations are normal during trenching and breaking up boulders. Engineers monitor vibrations to ensure they are within the anticipated and normal range.

Schedule and Construction MethodsPhoto of Night Work Construction

  • Beginning Monday, April 20, Northwest Natural crews will move a gas line on the shoulder of SW Taylors Ferry Road. Construction hours will be from 8:00 a.m. to 4:00 p.m. and construction will be completed by Friday. One lane in each direction will be maintained. Traffic delays will be minimal.
  • Crews will install an 84-inch manhole on SW Taylors Ferry Road south of SW Virginia Avenue. Manholes have been downsized to reduce disruption.



  • Install 84-inch manholes south of SW Fulton Park Boulevard (weekend work)
  • Install pipe and use cured-in-place pipe repair


  • Sawcut and trench SW Virginia
  • Begin installation of 84-inch and 96-inch manholes on SW Virginia

The contractor is using both open trench construction and cured-in-place pipe lining. The contractor uses excavators to cut pavement, and bypass pumps to move sewage around the work sites and to circulate steam through sewer pipes to cure the liner. The contractor may also use utility trucks, backhoes, and lights during night work hours.

Nighttime Construction

The Portland Noise Control Office granted Environmental Services a noise variance for overnight construction. Night work on SW Taylors Ferry Road is from 8:00 p.m. to 6:00 a.m. Monday through Friday. There will be work 24-hours for up to five non-consecutive weekends. Weekend construction hours will be 8:00 p.m. on Fridays to 6:00 a.m. on Mondays as indicated under Developments of Note section.

If you have questions or concerns during night work, you can call the City of Portland onsite hotline at 503-823-6659. You can also contact the Portland Noise Control Office at 503-823-7350 or

If you have questions or concerns about the project during regular business hours, please contact Ashley Tjaden at 503-823-5281. Environmental Services will also forward any noise-related comments to the Noise Office. 

Road Closure During Night Construction

Nighttime construction on SW Taylors Ferry Road began in early February. The overnight construction could last up to four months. During nighttime construction, SW Taylors Ferry Road will be closed to both local and through traffic from SW Macadam to just north of River View Cemetery and Riverview Abbey Funeral Home, both businesses will be open during construction.
