For general questions:
Remember, what goes down the storm drain goes to the nearest stream and eventually the Tualatin River. Unfortunately, some people use storm drains to dump hazardous waste which kills fish and pollutes our watershed. If you see someone dumping paint, oil, soap, fertilizer or other waste into a storm drain, report it to our Environmental Services department at 503.681.5175. If you have questions or concerns about pesticides, call our Natural Systems department at 503.681.3680.
