Rose City Park Sewer Repair

June 26, 2014

Environmental Services is repairing approximately 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. Repairing these pipes will help protect the public and the environment by reducing the possibility of sewage releases to homes, businesses and streets.

Current/Upcoming Construction Activities

  • Video Inspections – Crews are still in various areas of the neighborhood conducting video inspections of pipe at manhole locations.

  • NE 58th Avenue (north of Sacramento) – Sewer line construction continues on NE 58th Avenue, from NE Sacramento Street to a manhole just south of NE Alameda Street, near Rose City Park United Methodist Church. The work on NE 58th Avenue requires crews to excavate a trench in the street to lay the new main sewer line; the work will take a few weeks. After work crews install the main sewer line, they will repair lateral pipes on this street from the main sewer line to the curb. The contractor will maintain local access to individual properties but will prohibit on-street parking during daytime construction hours. Please watch for signage. The contractor will work on this street for about a month. After pipe installation, crews will apply a temporary pavement patch and come back later in the summer to apply permanent pavement.

  • NE 58th Avenue (south of Thompson) – A second crew will begin work on NE 58th Avenue south of Thompson. They will be sawcutting on NE 58th Avenue between NE Thompson and Tillamook streets the week of June 30 and then begin the pipe repairs after the Independence Day holiday. Two crews will be working throughout the summer.

  • Keep in mind that schedules are always subject to changes due to weather, supply availability, or other issues in the field.

The map below shows the location of pipes we will repair or replace. They are mostly in the Rose City Park neighborhood, with some blocks in the Madison South and Roseway neighborhoods. There may be temporary traffic controls, construction signage or increased traffic volume and parking on nearby streets.

What to Expect During Construction

  • Typical work hours are 7:00 a.m. to 6:00 p.m. Monday through Friday, but the contractor may schedule work during the same hours on Saturdays.
  • Construction will create noise, vibration and dust and will disrupt normal neighborhood activity.
  • Expect traffic delays. Traffic control signs will be 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 will be on-site during work hours and may be able to assist you with construction concerns. Inspectors typically wear a green safety vest with “City of Portland” across the back and a hard hat.
  • 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 actual 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.

Open trench installation is done in phases:

  • 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. For more information about the CIPP construction method and the chemical styrene, click here.
