To replace the aging 1964 Tryon Creek wastewater plant, Lake Oswego is undertaking a major capital investment in a new wastewater treatment facility which will produce cleaner water, withstand seismic and flood events, and ensure reliable service for generations to come.
Because sewer rates fund the sewer system, a rate increase is necessary to help fund this essential infrastructure investment.In September and October, the project team will be holding virtual community information sessions to provide an update on the project and discuss the proposed rate increases with the public.
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.
Paving is taking place on several streets in Lake Oswego in summer 2026. Paving activities may include extensive repair areas, grinding existing pavement, a new overlay or pavement of the driving lanes, new curb ramps, signal improvements, storm drains, and some waterline upgrades. Learn more about the streets being paved this year and what to expect.
Construction is underway through summer 2026 for a new sidewalk on the north side of McEwan Road, between SW 65th Avenue and Kristi Way.
Construction is underway for the new sidewalk on Carman Drive, between Waluga Drive and Quarry Road, through summer 2026. During construction, Carman Drive is open to one-way traffic westbound only, between Waluga and Quarry. Please obey detour signage for your safety.
