Alameda County is mourning the passing of former Alameda County Board Supervisor Scott Haggerty, a dedicated public servant who represented District 1 for over two decades.

President David Haubert, District 1, stated, “We are deeply saddened by the passing of former Supervisor Haggerty. His long-standing commitment to our community touched many lives, and we extend our heartfelt condolences to his family, friends, community, and former colleagues as they grieve this loss.”

Supervisor Nate Miley, District 4, served alongside Haggerty for decades, he stated, "I witnessed firsthand Supervisor Haggerty's unwavering commitment to improving transportation, strengthening our communities, and advocating for the residents he represented," Supervisor Miley wrote. "His leadership helped shape countless transportation projects and regional initiatives that will benefit generations to come. Scott’s legacy is one of service, vision, and steadfast dedication to the public good."

Haggerty was a valued partner and steadfast supporter of county administration as well, “Supervisor Haggerty will be most remembered for his dedication and for his countless
advocacy efforts to expand county services in the Tri-Valley. He also prioritized the county’s fiscal health to promote and protect the county’s long-term financial resilience.” said County Administrator Susan S. Muranishi.

The Board of Supervisors will pause to honor his memory at its next meeting on July 14, and flags at all county buildings will be lowered at half-staff.
