Environmental Services continues construction on the Woodlawn-King Streets Sewer Repair Project. The project will repair or replace over 16,000 feet (over 3 miles) of public sewer pipes in your neighborhood that are on average 90 years old and in deteriorating condition. This work will also include repairing or adding over 6,000 feet of service laterals that connect houses and businesses from the curb to the public sewer in the street. This project will protect the public and the environment by reducing the possibility of sewage releases to homes, businesses and streets.

Developments of Note

Paving will continue throughout the project area over the next several weeks as weather and crew availability allows.

Crews are scheduled to do open-trench construction to replace the mainline, as well as associated spot repair, manhole and lateral work, in the following locations:

  • N Williams Avenue between NE Dekum Street and N Rosa Parks Way
  • NE 10th Avenue between NE Wygant Street and NE Alberta Street
  • NE 11th Avenue at NE Wygant Street
  • NE 12th Avenue at NE Alberta Street
  • NE 8th Avenue between NE Alberta Street and Wygant Street
  • NE Sumner Street between NE 7th Avenue and NE Grand Avenue
  • NE Sumner Street between NE 8th Avenue and NE 11th Avenue
  • NE Dekum Street between NE Mallory Avenue and NE Garfield Avenue
  • NE 6th Avenue between NE Webster Street and NE Humboldt Street

Sewer Repairs using Cured-in-Place Pipe-Lining (CIPP) will occur in multiple locations in the coming weeks.

Over the coming weeks, crews are scheduled to conduct sewer repairs in several locations throughout the project area using a method called cured-in-place pipe sewer pipe lining which requires considerably less excavation than conventional pipe replacement. Work at each location will take about a day to complete.  Odors from the chemical styrene, which is the resin liner installed inside the pipe, may be detected during this work. The odor dissipates quickly once the installation process is complete. The amount of airborne styrene produced by the process is not expected to cause health issues for workers or the public. Your patience is appreciated during this work, which, similar to other sewer repair methods, may result in minor impacts to traffic flow.

Night Work on NE Dekum Street between NE 8th Avenue and NE Durham Avenue coming soon.

Sewer repairs on NE Dekum Street between NE 8th Avenue and NE Durham Avenue will be conducted one night only – Thursday July 19, 2018 into Friday morning, July 20, 2018 - to minimize impacts in this area. A noise variance was granted to allow for overnight construction at this location, and work is expected to take place Friday morning July 20 from 1 a.m. to 6:00 a.m., though exact work hours at may vary.

Concrete Paving: Did You Know?

Paving performed by Environmental Services is limited to replacing areas of roadway removed for construction. This means patching trenches we excavate to install sewer pipe, perform spot repairs or install cleanouts.

Occasionally, the footprint for sewer replacement work can become larger due to underground conditions or other circumstances. In those cases, the scope of our paving grows, as needed, to produce a structurally sound and functional roadway – not to address previous wear and tear such as pre-existing potholes or cracks. City staff takes photos of all streets, curbs, driveways, retaining walls and sidewalks before construction to document pre-construction conditions.
