For the first time in decades, there is a competitive race for the powerful position of Alameda sheriff, the county’s top cop. The sheriff oversees an office with far-reaching and wide-ranging responsibilities, while managing a massive budget and the East Bay’s largest law enforcement agency. Only two people have occupied the office since 1986, and neither ever faced a challenger in a single election. Until now. 

Sheriff Gregory J. Ahern, who has held the office since the previous sheriff retired and endorsed him in 2006, faces two challengers on the June 7 primary ballot: Alameda Sheriff’s Commander Yesenia Sanchez and San Francisco police Officer JoAnn Walker. 

The voter registration deadline is 15 days before the election, and early voting begins May 9. You can register here.

What does the sheriff do?

The sheriff sits atop a vast organizational chart. Besides needing a background in law enforcement or being certified as a deputy or police officer, the job comes with a number of administrative duties. The sheriff is in charge of the office’s budget, currently about $550 million, as well as 1,000 sworn deputies and 700 professional staff. 

When potential misconduct cases arise involving members of the sheriff’s office, the sheriff has the final say on discipline recommended during internal affairs investigations. 

Members of the office work throughout Alameda County in multiple offices and substations, serving about 150,000 residents in unincorporated areas in the Tri-Valley, San Leandro, Hayward, and Castro Valley. One of its primary tasks is operating Santa Rita Jail in Dublin, one of the largest county jails in the country. 

Sheriff commanders, who run search-and-rescue and dive teams, the crime lab, the gun range, and a regional training center, where current officers train, all work under the sheriff. 

Since most small police agencies do not have their own training academies, the sheriff’s office trains recruits who go on to work as police officers throughout the Bay Area and Northern California. Locally, only Oakland, San Jose, and San Francisco run their own police academies. 

The duties of the office also go beyond traditional law enforcement work. It performs orders of the court, such as serving eviction notices. The sheriff has the authority to issue or deny concealed-carry permits that allow citizens to carry firearms.

Sheriff Ahern is also the director of emergency services — like in the event of a major earthquake — for a region that covers the Bay Area and a large swath of Northern California. In those times, the county’s top cop can make emergency declarations and seek disaster funding through the state. 

The Coroner’s Bureau, which is also under the sheriff, conducts autopsies of people who die in car wrecks, overdoses, COVID-19 cases, and deaths by shootings, stabbings, blunt force trauma, and other suspicious deaths. 

Those reports by pathologists determine the cause of death and can be crucial pieces of evidence used in investigations, including people killed by the police. The sheriff also has the power to form a committee to determine the cause and manner of death in deaths caused by police officers or while in police custody. 

Who’s running

The first contested sheriff’s race in 36 years comes in the wake of a debate over law enforcement’s share of general fund dollars and the best ways to spend that money. Residents are also paying closer attention to police tactics, tools, and accountability for officer misconduct

In Alameda County, Ahern has had a strong support base in the Tri-Valley and southern parts of the county and within the sheriff’s administration. Supporters say he has the know-how to run both the law enforcement and administerial duties of sheriff, and that his years in the office set him apart. 

He has a fair share of critics in Oakland and Berkeley. The sheriff has faced backlash over his cooperation with federal immigration agents, the controversial Urban Shield training program, which critics said focused more on the militarization of police and tactics viewed as oppressive to communities of color instead of a focus on disaster preparedness, and problems at Santa Rita Jail, which were highlighted in a federal civil rights investigation over the treatment of detainees with mental health issues, and two class-action suits. In February, a judge placed the jail under federal court supervision for at least six years. 

Under current state law, candidates for the county sheriff’s office must have either an advanced certificate from the state’s Commission on Peace Officer Standards and Training or a certain amount of recent full-time law enforcement experience. Building up to this year’s campaign, police reform activists had sought to widen the pool of candidates who could challenge Ahern by backing S.B. 271, a bill that aimed to dramatically lower the eligibility requirements so that any registered voter could run. The bill failed. 

Nevertheless, two candidates with long law enforcement careers have stepped up to challenge Ahern.

Walker, a Hayward resident, has worked as a San Francisco police officer for 26 years in various capacities including as an academy instructor, terrorism liaison officer and community relations liaison. She has emphasized her experience handling domestic violence cases, crisis support and suicide prevention support as a volunteer in Alameda County. 

Walker entered the race early as a progressive candidate and on the promises of addressing the high number of in-custody deaths at the county jail, increasing transparency around the sheriff’s budget, and cutting the backlog of untested rape kits. 

Sanchez joined the sheriff’s office as a technician in 1997 and rose up the ranks. She’s worked at the now-defunct North County Jail both as a technician and lieutenant, on patrol assignments, and as a captain in support services. She currently is a division commander overseeing and managing Santa Rita Jail. 

Her top priorities include rehabilitation and job training for incarcerated people, racial justice in law enforcement, holding the sheriff’s office accountable, and improving relationships with the community.

If none of the three candidates get 50% or more of the vote in June, there will be a runoff election between the top two vote-getters in November.
