Sellwood-Moreland Sewer Repair Project

Sellwood-Moreland Sewer Rehab Project Construction Update: March 17, 2015   

Environmental Services is repairing or replacing about 25,000 feet of public sewer pipes in the Sellwood-Moreland neighborhood that are between 80 and 100 years old and failing due to age. This project will help protect the public and the environment by reducing the possibility of costly breaks, leaks, blockages and sewage releases to homes, businesses and streets.   


We still do not yet have a date for the start of work to repair the mainline sewer on SE 17th Avenue between Rex Street and Bybee Boulevard. We appreciate your patience and cooperation!


Below is the anticipated construction schedule for the next three weeks. The schedule is subject to change due to a variety of factors, including underground conditions, weather, subcontractor schedules and availability of materials. As the contractor completes construction on each street, work crews apply a temporary patch. They will return at a later date to apply permanent paving. 

Week of March 16:

  • If weather conditions allow, crews hope to complete final paving and concrete work this week at:
    • SE 22nd Avenue between Yukon and Bybee
    • SE Tolman Street between 21st and 22nd
  • SE 20th Avenue (between Tolman and Claybourne) – install manholes
  • SE Rural Street (between 13th and 16th) – install manhole and connect individual sewer branches to new mainline, prepare for pipe bursting between 16th and Milwaukie

Week of March 23:

  • SE 20th Avenue (between Tolman and Claybourne) – install manhole and reconnect individual sewer branches to new mainline
  • SE Rural Street (between 13th and 16th) – conduct pipe bursting between SE 16th and Milwaukie, and install manholes and connect individual sewer branches to new mainline between SE 13th and 16th. 
  • SE Clatsop Street and 21st Avenue – install manhole and stormwater drain at intersection
  • SE 21st Avenue (between Miller and Lambert) – install manholes at intersections and in front of 2038

Week of March 30:

    • Paving around the intersection of SE 18th Avenue and Yukon Street will be completed when weather allows
    • SE Milwaukie and Lambert – install stormwater drain
    • SE 20th Avenue (between Tolman and Claybourne) – reconnect individual sewer branches to mainline
    • SE 13th Avenue (between Ogden and Rural) - prepare for and conduct pipe bursting, install manhole
    • SE Milwaukie and Lambert – install stormwater drain
    • SE 21st Avenue (between Miller and Lambert) – install manholes at intersections and in front of 2038

Note: Though our work may be directly in front of specific homes, all homes on the block are likely to be impacted by noise, traffic disruptions, and presence of equipment.

What to Expect During Construction

The following are answers to some of the most frequently asked questions we receive from neighbors about construction:

  • Work hours: Work hours are 7:00 a.m. to 6:00 p.m. Monday through Thursdays for most work.  If needed, the contractor may work the same hours on some Fridays and Saturdays. The contractor will work at night to complete the cured-in-place pipe lining on larger pipes in several locations (see map). We will notify residents in advance of night work.
  • Expected impacts: Construction creates noise, vibration, dust and traffic impacts. Also, equipment and materials may need to be stored on some city streets.
  • Traffic: Expect traffic delays. The contractor will set up traffic control signs and flaggers may direct traffic on higher-volume streets. Orange barricades and signs reading “ROAD CLOSED to Thru Traffic – Local Access Only” are intended to reduce overall traffic going through the area while construction is underway, but anyone who lives in or needs to conduct business within the construction zone will be allowed access.
  • Parking: On-street parking in or near the work area is prohibited during work hours and you may be delayed getting to your driveway. Please plan to move your vehicle by 7:00 a.m.
  • Planting strip and sidewalks: Sewer construction generally occurs in the street. However, in a few areas the contractor will have to cut into sidewalks or driveway edges then restore the areas. Construction may also affect the planting strip, or the area between the curb and sidewalk. We will notify property owners where this may occur.
  • Advance notice: We will post doorhanger notices a few days before work starts on your street. Keep in mind that schedules are always subject to change due to weather, supply availability, or other issues in the field.
  • Sewer and water service: During construction, the city’s contractor will use by-pass pumps to maintain sewer service. If a short, temporary sewer service shut-off is necessary to relocate a line, the contractor will notify property owners in advance.
  • Construction duration: Construction near an individual property could last a few weeks. This may seem longer where the work extends on the same street for a block or more. Sewer construction has many phases, and there may be periods of inactivity between construction phases at each site.
  • Safety: 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. A city inspector will be on-site during work hours and may be able to assist you with construction concerns. Inspectors wear a hard hat and a City of Portland safety vest.
