Stormwater and Water Quality

You can help keep local waterways healthy

Anything on a roof, driveway, parking lot, sidewalk, and even your lawn or garden can be washed into a storm drain.  It's up to all of us to connect the dots and keep pollution out of our waterways.  See our tips and resources below.


Pesticides and Fertilizers

Pet Waste

Car Washing

  • Use phosphate-free and biodegradable cleansers or just water
  • Use rolled-up towels to divert wash water into a grassy or gravel area to allow the ground to filter pollutants
  • Read our fact sheet for more tips on stormwater-friendly car washing
  • To borrow a Fish-Friendly Carwash Kit for your carwash fundraiser, call 541-682-4929

Pressure Washing

  • Start with dry absorbents, sweeping and vacuuming
  • Filter runoff, divert it into landscaped areas, or pump it into the sanitary sewer to keep debris and chemicals out of storm drains
