Washington County has activated all three of the snow zones. Locations are as follows:

  • 175th Avenue, between Scholls Ferry and Rigert roads.(Activated Dec. 26)
  • Barnes Road, 118th Avenue east to the County line, adjacent to a city of Portland snow zone.
  • Cornell Road, Cedar Hills Boulevard east to the County line.

Motorists are required by law to use traction control devices – including chains, studded tires, Mountain Snowflake tires, winter tires or “tire socks” – on their vehicles or avoid these areas. The citations carry a fine of up to $160.

The Washington County Department of Transportation and Land Use (LUT) may need to have abandoned vehicles towed off the roads as they may pose a safety hazard. They can affect the visual field of drivers and impede the passage of snow plows, emergency vehicles and public transport.
