AUBURN, Calif. – Placer County is celebrating its 175th anniversary this year, marking a milestone that reflects generations of community, innovation and resilience.

Established on April 25, 1851, the county’s story is deeply tied to the California Gold Rush, when prospectors first arrived seeking opportunity in the Sierra foothills. Over the decades that followed, agriculture, the development of the First Transcontinental Railroad and the mobilization during World War II all played key roles in shaping the communities that make up Placer County today.

“Placer County has a remarkable story built by generations of residents who helped shape the community we enjoy today,” said Placer County Executive Officer Daniel Chatigny. “Our 175th anniversary is an opportunity to celebrate our past, recognize the people and industries that built this county and look ahead to a bright future.”

County staff created a 175th anniversary emblem to celebrate the region’s legacy. The emblem features golden 175 numerals in a nod to the gold rush along with snow-covered mountains, the Foresthill Bridge and rolling agricultural farmland.

Residents and visitors alike are invited to join the celebration through a series of community events taking place across the county, from Lake Tahoe to Roseville, as the county honors this important milestone in its shared history.

In the months ahead, the county will also launch opportunities for residents to learn more about local history and share their own history through the county’s online engagement platform, Engage Placer.
