Sellwood-Moreland Sewer Repair Project

Sellwood-Moreland Sewer Rehab Project Construction Update: April 21, 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.   

DEVELOPMENTS OF NOTE

Sewer repairs have begun on SE Milwaukie, between Henry and Duke, in front of QFC.  Flaggers will maintain traffic flow and we will inform you of updates as work progresses on the block.  Street parking will be unavailable and the sidewalk on the east side of the street will be closed during much of the work. 

Construction on the mainline sewer on SE 17th Avenue between Rex Street and Bybee Boulevard has been rescheduled.  Some of the preparation is beginning this week, and the street closure is scheduled to begin early next week, around April 27th.   We appreciate your patience!

CONSTRUCTION SCHEDULE

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 April 20:

  • SE Milwaukie Avenue (between Henry and Duke) – open trench construction to repair individual sewer branches
  • SE 17th Avenue (between Bybee and Rex) – prepare for pipe lining
  • SE Ogden Street (between 13th and 16th) – repair one spot in pipe
  • SE Ogden Street (between 16th and Milwaukie) – connect sewer branches to individual properties
  • SE Knapp Street (between 14th and 16th) – prepare for pipe bursting

Week of April 27:

  • SE Milwaukie Avenue (between Henry and Duke) – possible continued open trench construction to repair individual sewer branches
  • SE 17th Avenue (between Bybee and Rex) – prepare for pipe lining by installing branches to individual properties
  • SE 21st Avenue (between Lambert and Miller) – install manholes in intersections
  • SE Ogden Street (between 16th and Milwaukie) – open trench excavation to repair section of mainline closest to Milwaukie.  Note: Original plan for pipe bursting changed due to additional field investigations.
  • SE Knapp Street (between 14th and 16th) – prepare for and conduct pipe bursting, connect individual sewer branches to mainline
  • SE 9th and Ochoco Street – replace manhole at intersection

 Week of May 4:

  • SE 17th Avenue (between Bybee and Rex) – prepare for and conduct pipe lining
  • SE 20th Avenue and Claybourne – install manhole in intersection
  • SE Nehalem Street (between 6th and 7th) – install manholes in intersections
  • SE 21st Avenue (between Lambert and Miller) – install manholes in intersections
  • SE Knapp Street and 14th Avenue – connect new mainline to existing manhole in intersection
  • SE 15th Avenue (between Lambert and Bidwell) – open trench construction on mainline and install manholes
  • SE 9th Avenue and Ochoco Street – replace manhole in intersection
  • If weather conditions allow, crews hope to complete final paving this week on:
    • SE 21st Avenue (between Marion and Linn and between Sherrett and Clatsop)
    • SE Clatsop Street (between 19th and 21st)
    • SE 19th Avenue (between Clatsop and Linn)
    • SE Linn (between 17th and 19th)

 Within the next three weeks, crews also plan to pour concrete around manholes and stormwater drains at the following locations, as needed:

  • SE 22nd Avenue (between Tolman and Claybourne)
  • SE Tolman Street (between 20th and 22nd)
  • SE Clatsop Street (between 19th and 21st)

Sellwood-Moreland Sewer Project mapWhat 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.
