Rose City Park Sewer Repair

December 19, 2014 

Environmental Services is repairing about 40,000 feet (7.5 miles) of public sewer lines in your neighborhood that are between 60 and 100 years old and failing due to age. The project will help protect the public and the environment by reducing the possibility of sewage releases to homes, businesses and streets. 

Current Construction Activities

Three construction crews have been working on sewer and lateral pipe repairs in the area. Please be aware that construction schedules are subject to change due to conditions underground, weather, traffic, subcontractor schedules and availability of materials. You will notice several phases as different equipment or specialized crews are required at each site.

 Holiday schedule:

  • Crew plan to clean up work areas on December 24th and break for the holidays. They will return to work on January 5th, 2015.

 Sewer repair locations underway:

  • NE Tillamook between NE 72nd and NE 73rd avenues have been completed. The road has been prepared so that the Bureau of Maintenance can schedule final paving.
  • Spot repairs continue at the following locations:
    • NE 62nd Avenue between NE Alameda Street and Sandy Boulevard
    • NE 61st Avenue between NE Alameda and Stanton Streets
    • NE 65th Avenue between NE Halsey and Tillamook streets
    • NE Clackamas and Hassalo streets between NE 60th and 62nd Avenues
    • Street restoration – Where pipe spot repairs have been completed, there are still several areas with temporary asphalt patches. Crews are waiting for better weather to do the permanent restoration of those areas.

 Upcoming:

  • The following areas will be started as crews wrap up in other areas:
    • NE 64th Avenue between NE Broadway and Tillamook Streets
    • NE 65th Avenue at NE Hancock, southeast to NE 66th and Broadway (road curves through the Ellington Apartments complex)
    • NE 56th Avenue between NE Halsey and Thompson Streets

 Other activities in the field:

  • Video inspections of pipe throughout the area

What to Expect During Cured-in-Place Pipe Lining

  • Construction crews access sewer pipes through manholes in the streets.
  • You may notice an odor during the pipe lining process but it will dissipate quickly. To help reduce odors, run water in all sinks and basins to fill P-traps and completely cover floor drains with a wet towel or a zip bag filled with water. Keep in mind that schedules are always subject to changes due to weather, supply availability, or other issues in the field.

What to Expect During Construction

  • Construction creates noise, vibration and dust and disrupts normal neighborhood activity.
  • Expect traffic delays. Traffic control signs are set up and flaggers may direct traffic on higher-volume streets. You may see barricades and orange signs reading “ROAD CLOSED to Thru Traffic – Local Access Only.” These signs 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.
  • On-street parking in or near active work areas is prohibited during construction hours. Please plan to move your vehicle by 7:00 a.m.
  • Equipment and materials may be stored on nearby streets overnight.
  • There may be periods of inactivity between construction phases.
  • A city inspector is on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a hard hat and a green City of Portland safety vest.
  • Please stay clear of all construction activities and keep children and pets out of construction areas.
  • You should receive a doorhanger notice a few days before repair work starts on your street. You may notice pre-construction activities like survey or sewer inspections in advance.

Sewer Construction Methods

The city will use a combination of open trench construction and cured-in-place-pipe lining (CIPP). The contractor may use more than one construction method in some areas. 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.

There are several phases of open trench construction:

  • Saw cut pavement along the width of the trench
  • Remove pavement and existing material
  • Install public sewer pipe in the street
  • Backfill trench with sand or gravel
  • Replace laterals that connect private sewers to the system (from the curb to the street)
  • Restore surface temporarily with an asphalt patch
  • Complete final paving
  • Restore other areas disturbed by construction, such as sidewalks, driveway aprons and planting strips

Cured-in-place-pipe lining (CIPP) doesn’t require digging a trench. Work crews access the sewer from manholes to insert a flexible liner inside the old pipe. Hot water or steam inflates and cures the liner, which gradually hardens to form a rigid, smooth surface that seals cracks and restores the pipe to near-new condition. People who live and work near a CIPP repair project sometimes smell a chemical odor during the pipe-lining work. 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 produced is not a human health risk. Get more information about CIPP construction.
