Wastewater Treatment Facility - Proposed Rate Increase & Information Sessions

To replace the aging 1964 Tryon Creek wastewater plant, Lake Oswego is undertaking a major capital investment in a new wastewater treatment facility. A rate increase is necessary to help fund this essential infrastructure investment.

During their September 1 meeting, City Council evaluated two rate options: a one-time 28% increase, followed by annual inflationary adjustments of about 3.9% or an 8% annual increase for 10 years, followed by annual inflationary adjustments of about 3.9%.Council will determine which approach to take at their October 13 meeting.

Learn More: Join a virtual community information session on September 16 or October 1 to learn more about the project and proposed rate increases, or visit the project webpage to sign-up for e-news. Register in advance here.

Busy Construction Season is Here!

We have an extremely busy summer of construction work upon us, as many public utility and roadway projects will be taking place throughout Lake Oswego. Work includes paving, sidewalk pours, curb ramps, sewer rehabilitation, water lines, pump stations, bridge repairs, traffic signal upgrades, and stormwater improvements. Some of these will result in lane closures, flaggers, or one-way traffic, others will require road closures with traffic detours in place. Most work will be taking place during the day, but some paving work will take place at night. Please be alert, drive safely, follow signage, and plan ahead for travel delays.

Go sLOw: 20 is Plenty

In September 2025, City Council approved an ordinance to lower the speed limit on local residential streets and some neighborhood collectors in Lake Oswego from 25 miles per hour (mph) to 20 mph.

Public Works crews are rolling out the Go sLOw speed reduction program, moving clockwise one neighborhood at a time. Phase 1 includes replacing existing 25 MPH signs and was completed in late 2025. Phase 2 adds new posts and additional signs and is underway through summer 2026.

New speed limits take effect as soon as the signs change.
