SE Hawthorne Boulevard Sewer Project

Updated May 19, 2020

Keep 6 feet apartSign up for email!




The City of Portland’s Bureau of Environmental Services is continuing our work to repair and replace critical sewer and stormwater infrastructure. Environmental Services will continue to provide information and updates on construction schedules and activities during the COVID-19 emergency.  

Environmental Services – your sewer and stormwater utility – is constructing a project in your neighborhood to upgrade sewers on SE Hawthorne Boulevard between SE 31st through 40th avenues. There are some side streets to the north of Hawthorne that will also be included in the work (SE 31st, 37th, 38th, Madison between 37th and 38th, and 40th). This sewer project will upgrade and install 2,900 feet of sewer mainline. The addition of new larger pipe will address basement sewer backups, reduce street flooding, and help protect public health and the environment.  

This project was previously part of the Sunnyside South Green Street and Sewer Project. It was separated from this larger project in order to complete the sewer work before the Portland Bureau of Transportation’s (PBOT) Paint and Pave Project occurs on SE Hawthorne in the spring/summer 2021.

Developments of Note

Crews are finishing portions of the project quicker than anticipated. The schedule is moving ahead and there are some changes that have developed since the previous update.

Sewer Construction Schedule 

Below are the anticipated construction activities for the remainder of this week and next. The schedule is changing weekly based on progress by the contractor.  Please note that the schedule can change for a variety of reasons, including weather, equipment and supply availability, and coordinating with crews and subcontractors. Crews are installing sewer mainline and sewer connections with two crews working from 7am – 6pm, Monday through Friday: 

Week of May 18 (Changes added):

  • Continue SE Hawthorne Blvd mainline sewer and connections between SE 33rd and 34th avenues
  • Set up to start work on SE 40th Avenue between Hawthorne and Madison
  • Finishing SE 37th Avenue between Hawthorne and Madison
  • Start work on SE 38th and Madison as soon as Thursday and work on sewer mainline and connections on Madison between 37th and 38th.
  • Starting on ADA ramps
  • Starting some concrete restoration/reinforcement work on SE Hawthorne between 31st and 32nd. 

Week of May 25 (no work on Monday, May 25 due to holiday) – Changes added:

  • SE 40th Avenue mainline sewer and connections between SE Hawthorne and Madison
  • SE 38th Avenue mainline sewer and connections between SE Hawthorne and Madison
  • Continue concrete work on SE Hawthorne between 31st and 32nd, moving to Hawthorne and 32nd Place, and Hawthorne between 33rd and 34th avenues
  • Continue ADA ramps

What to Expect During Construction

You can expect the following activities and impacts during construction:

  • Flaggers will assist vehicles and pedestrians safely through work zones. Sidewalks will remain open, except where corner ADA ramps are being constructed
  • Expect traffic delays in and near the work zone.
  • On-street parking will be temporarily removed in and near the work zone during work hours.
  • Equipment and materials may be stored on streets overnight.
  • Sewer, water, and other utilities are expected to remain in service during construction.
  • Construction creates noise, vibration, and dust and may disrupt normal neighborhood activity.
