Environmental Services is completing designs 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.
What's Happening Now
Over the next few months, crews will be in the neighborhood locating utilities, surveying, and drilling to take soil and pavement samples. This information will help engineers decide which locations need repair and what construction methods are best for each location. These information-gathering activities typically occur over time, rather than all at once. Visit the Pre-Construction Activities webpage for more details about pre-construction activities.
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.
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.
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.
