Public Works

The Lake Oswego Public Works Department is responsible for maintaining infrastructure systems throughout the City to ensure they are working correctly, efficiently, and that the life of our assets is maximized. Streets, Water, Sewer, Stormwater, Motor Pool and City Beautification maintenance programs make up the department with each responsible for their own infrastructure system.

Here at Public Works, we take pride in providing utility maintenance to help make Lake Oswego a great place to live.
