Stormwater Curb Markers

A City of Hillsboro curb marker. A circular marker that contains images of a person kayaking, fish, ducks, and a faucet pouring a glass of water. The text reads No Dumping, Drains to River, City of Hillsboro, 503-681-6146.

To remind residents and visitors that catch basins flow to local waterways, the City of Hillsboro Public Works Department is placing curb markers on catch basins across the City.

The City of Hillsboro maintains over 7,800 catch basins. Catch Basins are typically curbside grates or inlets on streets that collect stormwater and carry it to nearby streams and rivers.

Impact of Pollution

Federal, state, and local laws prohibit dumping of any kind down catch basins. 

Pollutants such as dirt garbage, yard debris, and chemicals can harm the aquatic plants and wildlife of our local streams, rivers, and creeks. Once pollutants drain into the Stormwater System, the City may not be able to prevent them from entering our local waterways.

Keep Local Waterways Healthy

Did you know your garden hose, sprinklers, and rain can wash chemicals and waste from your home, driveway, yard, and garden into catch basins?

Help us keep our streams and rivers clean by following these six tips:

  • Reduce the use of chemicals in your yard.
  • Pick up after your pets and place pet waste into the garbage.
  • Use phosphate-free and biodegradable cleansers or just water.
  • Rake leaves back to prevent catch basins from becoming clogged during storms.
  • Pick trash up before it goes down the catch basin.
  • Clean driveways and sidewalks with a broom or a leaf blower instead of a hose.
