Sonoma-Marin Fair Briefing

It’s not just a Fair.
It’s a community, gathering place, & EMERGENCY CENTER!

First and foremost, the Sonoma-Marin Fair Board expresses its sincere appreciation to community members advising the City of Petaluma on this project.The fate of the Sonoma-Marin Fair and the future use of the historic property – the fair’s home for more than a century – is a complex, emotional and contentious issue. The decisions made by the advisory panel will not only impact the landscape of downtown Petaluma but the city’s identity and culture as well. The panel’s recommendations will affect our youth, non-profit organizations, farm families, and city neighbors who consider the fair and fairgrounds part of Petaluma’s way-of-life.
