Storm Drain Marking

City of Lake Oswego Storm Drain Marker

The goal of the program is to help our community realize that anything that is poured down the storm drain or collected with rainfall ends up in our local rivers, streams and Oswego Lake. This storm drain marker, together with the informational door hanger, are visual reminders that only rain belongs down the storm drain.


Installing storm drain markers is an ideal project for community groups, churches, scouts or neighborhoods. Children as well as adults can install the markers. We recommend you have at least six people in your group. Click here for a link to the City's Volunteer page to get started!


There is no cost for this program - the City of Lake Oswego supplies all the materials. To check out materials, please contact David Gilbey, Water Quality Program Coordinator, at 503-675-3999.
