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.
News & Announcements
A flood watch and wind advisory is in effect for NW Oregon and SW Washington, with periods of heavy rain and wind Monday 12/8 through Wednesday 12/10. Our Public Works team is all hands-on deck clearing and checking catch basins and monitoring conditions. Let’s make sure we’re all prepared to weather this storm together. Please do your part by clearing debris and leaves from nearby catch basins and guttters with a rake or shovel. This helps water flow freely, reducing the risk of local flooding.

Proper disposal of fats, oils and grease protects your home, business, public health, and the environment.
The City sweeps every neighborhood on a regular rotation using our main sweepers, Oscar and Sweep Caroline. They work zone by zone, Monday through Friday, and some weekends. While they can sweep the whole city in about a week during spring and summer, fall and winter take longer due to heavy leaf and pine needle buildup. Thank you for your patience as crews make their way through each zone.
You can help sweeping be more efficient by keeping leaves and yard debris out of the street. Please do not rake, blow, or pile leaves into the roadway, as this clogs and damages equipment and is also against City code.
Our Public Works Department diligently follows weather reports, monitors local weather stations and road conditions, prepares for, and is ready to respond to winter weather events.

As leaves fall, storm drains can get blocked by debris, leading to localized flooding. These drains are vital for keeping streets and sidewalks clear of excess rainwater as well as maintaining stormwater quality standards. Simply clearing leaves and debris from the surface of catch basins near your property with a broom or rake can keep the drainage system functioning well.
The City has a limited number of free drop boxes available to support neighborhood clean-up events through a contract agreement with Republic Services. Neighborhoods can apply for a free drop box to help collect neighborhood leaves.
There is no such thing as a flushable wipe – even the ones that say flushable. “Flushable” wipes cause serious damage to sewer systems and homes because they don’t break down or dissolve, clogging sewer pipes, damaging equipment, and causing expensive repairs for homeowners and our public sewer system.
Do not flush wipes! The only items that should be flushed down the toilet are toilet paper and human waste. Other items, like wipes, should be thrown in the trash.
We want your help in making community streets a safer and more comfortable place. While staff work diligently on addressing issues that are spotted, we understand that we can’t catch everything.
