Sellwood-Moreland Sewer Rehab Project Construction Update: January 20, 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.
Below is the anticipated construction schedule for the next three weeks. This 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 asphalt patch. They will return at a later date to apply permanent paving.
Week of January 19:
- SE 22nd Ave (between Tolman and Claybourne) - open trench construction on mainline for southern half of block (south of 6414), manhole repair in front of 6414, 6415, 6424 and 6425
- SE Knapp (between 13th and 14th Ave) – installation of branches to individual properties and open cut spot repairs in front of 1339, 1340, 1351, and 1354
- SE Rex (between 9th and 11th Ave) - installation of branches to individual properties and open cut spot repairs in front of 906 and 926 SE Rex and in back of 916 and 926 SE Sellwood Blvd)

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 equipment.
Night Work at Several Locations
The Portland Noise Control Office granted Environmental Services a noise variance for nighttime construction at several locations in this project (see map below). A city inspector will be on-site during this night work. To report concerns during night work, please call the on-site hotline at 503-823-1257. You may also call the Portland Noise Control Office at 503-823-7350 or email firstname.lastname@example.org.
Cured-in-place Pipe Lining Locations
The contractor will use cured-in-place pipe lining (CIPP) to repair several sewers. Work crews may install lining at night at some locations because of the size of the pipe. Work at each location should take no more than a few days. People who live and work near a CIPP repair project can sometimes smell a chemical odor during pipe-lining. The odor is from the chemical styrene, which is in the resin liner installed inside the pipe. The odor dissipates quickly once the installation process is complete. The amount of airborne styrene the repair process produces is not a human health risk. More details about CIPP are available at www.portlandoregon.gov/bes/64780.
Other Sewer Construction Methods
The city's contractor is using a combination of open trench construction, cured-in-place-pipe lining, and pipe bursting. For example, the contractor may use CIPP on the main public sewer pipe and open trench construction to repair or replace laterals that connect private sewers from the curb to the public sewer in the street. Details about each construction method are available at www.portlandoregon.gov/bes/64780. The contractor may use more than one construction method in some areas.
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: Typical construction hours are 7:00 a.m. to 6:00 p.m. Monday through Friday. If needed, the contractor may work the same hours on 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.
