NW Portland Sewer Extension Project

Sewer and Stormwater
Environmental Services is in construction on a project to add 1,080 linear feet of sewer pipe in NW Portland. Sewer extensions will allow direct access to the sewer system for properties that currently receive service through a neighboring property.
Construction started at the end of June and will take a year to complete. Approved work hours are 7 a.m. to 6 p.m., Monday through Friday.

General Schedule

Construction will start at the end of June and will take a year to complete. Approved work hours are 7 a.m. to 6 p.m., Monday through Friday.


Over the next three weeks, crews will install sewer pipes using the open trench excavation method, install maintenance holes, and complete final paving and restoration.

  • Final surface restoration and clean up on NW 21st Avenue just south of Wilson.

Week of October 18 activities include:

What to Expect During Construction

The contractor will develop detailed traffic control plans before construction begins. You can expect the following activities and impacts during construction: 

  • Noise, Vibration, and Dust: Construction creates noise, vibration, and dust and disrupts normal neighborhood activity. 
  • Equipment Storage: Equipment and materials may be stored on streets overnight. 
  • No Parking: Little or no on‐street parking will be allowed in and near work zones, especially during work hours. On days when crews will be working in front of your house or nearby, please plan ahead. If you park your vehicle on the street, plan to move it off the street by 7 a.m. and return it at 6 p.m. 
  • Traffic Delays: Expect traffic delays in and near the work area. 
  • Services Maintained: Sewer, water, and other utilities are expected to remain in service during construction. 
  • Garbage Pickup: Access to garbage and recycling bins for haulers will always be maintained.

Safety Around Construction

Safety is our top priority for the public and our crews. Please use caution and stay outside of the work zone. If you need to get the attention of a crew member, please do so from the sidewalk or contact Joe Tursi, the community outreach representative for the project. We understand that construction can have many impacts on people living and working in the area, and we appreciate your patience and understanding while we perform this necessary sewer work.

Construction Methods

Open Trench Excavation will be necessary to install the new sewer extensions and sewer service laterals to adjacent properties. It consists of excavating down to the required depth for the sewer system, installing the new pipe, then backfilling the trench, and completing final pavement restoration of the trench after the work passes inspections.

How to prepare for construction

If you have a concern about any items or features inside your house or other structures that you think might be vulnerable to construction vibration, we recommend that you secure them before construction begins at your property. Secure hanging items like photos, china dishes, or ceramics, or remove them temporarily before construction begins. Items on shelves may rattle and move, so take precautions you think are necessary. We also recommend that you take photos and/or videos to document pre-existing conditions inside your house, including existing cracks on ceilings, walls, and floors. Be sure photos and videos are date-and-time-stamped for verification. 

On-Street Parking—Please Plan Ahead

The city’s contractor for this project has posted NO PARKING signs in and around areas where crews are working and staging equipment and materials. On days when crews will be working in front of your house, nearby, or where you park your vehicles on the street, please plan ahead. Plan to move your vehicles off the street by 7 a.m. and return them at 6 p.m. Monday through Friday. Keeping your vehicles parked on the street puts them at risk of being towed, delays the work, and extends the inconvenience. Thank you for your cooperation.

If you know that you will be away from home for an extended period, such as a week or two, please plan ahead and arrange to store your vehicles off the street if possible. You may also check in about the tentative schedule for construction on your street to avoid conflicts. We want to make sure that you keep your vehicles safe and that our crews can do their work. Thank you. 

We Want to Hear from You

Please let us know if you have a concern or question about the project. Be sure to include your name, property address, and project name (NWSE) in your voicemail and email so we can provide you more details about what to expect in front of your property. Also, please write “NWSE” in the subject line of your email.  

Environmental Services will be working with our contractor to do all we can to minimize construction impacts on the neighborhood. Construction is noisy, dusty, and causes vibration. It will be disruptive.
