Fair, Fair Board, and Westside Commons

Westside Commons, home of the annual Washington County Fair, is a multi-use campus located in Hillsboro, Oregon, that is dedicated to serving the entire community by hosting and producing national-class events on a local scale.

The Board of County Commissioners and the Fair Board are exercising a collaborative approach toward conducting a high-quality Fair event each year and maintaining and improving facilities and property at the Fairgrounds, now rebranded as Westside Commons, over the years ahead.

Emergency Livestock Evacuation Plan

In the event there is an emergency that necessitates our Fairgrounds to be used as a shelter for evacuated livestock, we want to assure you we will be operating and available to take in your livestock. Should a livestock evacuation be necessary, go to, our Fair website, and we will have more information to help you at that time, but please know our team is prepared to help you!

Coordination and resource sharing between the Fair and the rest of the county government organization stems from an agreement adopted in 2010 by the Board of County Commissioners and the Fair Board. The Fair and Fairgrounds Agreement, in the form of a memorandum of understanding (MOU), is designed to clarify and reinforce the partnership between the Fair Board and Board of Commissioners in support of the annual Fair event and fairgrounds property, now re-branded as Westside Commons. The agreement memorializes a more focused role for the Fair Board: to plan, prepare and produce the County Fair. The agreement also discusses the creation of a Fairgrounds Advisory Committee (FAC) to provide advice and counsel to the Board of Commissioners on the Fairgrounds Master Plan, Fairgrounds Capital Projects Plan and other major site-related initiatives.
