  • Between 5th and Park avenues: CCTV cameras and root removal within manholes
  • Between Park and 10th avenues: Prep work in the sidewalk

The week of March 27:

Pre-construction and maintenance work will continue along Yamhill and Morrison Streets between 1st and 13th Avenues, along Stark between Naito and 2nd, and along 5th between Taylor and Yamhill. Activities include cutting roots from sewer pipes, flushing the pipes with water to clear debris, documenting pipe conditions via video cameras, evaluating and installing sewer cleanouts, and taking photos of the work area for documentation.

What to Expect during Construction

Expect minor traffic delays, traffic control signage, and flaggers as needed within the work area. For details about ongoing activities and impacts to expect during construction, read the Project Overview.
