East Bay Encryption: How Two Counties Coordinated a Regional Blackout
$1.5M+ spent. Multiple setbacks. And Berkeley—the last holdout—eventually fell too.
Key Facts
The Regional Coordination
The East Bay encryption was not a single city's decision. The East Bay Regional Communications System Authority (EBRCSA) managed a coordinated transition spanning two counties and dozens of agencies, spending over $1.5 million on the encryption upgrade between July 2022 and June 2024.
Affected areas
Alameda County
Population: ~1.7 million
- Oakland Police Department
- Fremont Police Department
- Hayward Police Department
- Berkeley Police Department (last to encrypt)
- Alameda County Sheriff's Office
- Multiple smaller agencies
Contra Costa County
Population: ~1.2 million
- Richmond Police Department
- Concord Police Department
- Walnut Creek Police Department
- Contra Costa Sheriff's Office
- Multiple smaller agencies
Combined impact: Nearly 3 million residents lost access to police radio communications.
Timeline: technical glitches and delays
The rollout faced multiple setbacks. Technical failures delayed what was planned as a coordinated regional cutover.

Berkeley: last holdout falls
Berkeley was the last agency in Alameda County with open police radio. Once every surrounding agency encrypted, the department's position became politically untenable.
Police Chief Jen Louis's Arguments
- "We've caught burglars listening to our unencrypted channels"
- Berkeley is now "only agency in Alameda and Contra Costa counties with public police channels"
- Open channels would "concentrate criminal attention on Berkeley"
- California DOJ guidance requires protecting certain private information
Community opposition
- "The scanner has long allowed residents, journalists and volunteer responders to stay informed in real time" — Berkeley Scanner founder
- "Especially during critical incidents like fires, protests or citywide emergencies when accurate information can literally save lives" — Fire Safety Commission EMT
- "When you encrypt radios, public information becomes sort of discretionary information" — Media Alliance
The final vote: 8-1
The Berkeley City Council voted to encrypt. One member dissented on transparency grounds. Regional pressure—Berkeley now stood as the only open agency in two counties—outweighed the community opposition that had organized in the two weeks between the surrounding cutover and the vote.
Cost breakdown
Regional encryption was expensive on top of the EBRCSA's $1.5M+ investment. Individual agencies added hundreds of thousands of dollars each.
Note: This is a partial accounting. Many agencies' individual costs remain undisclosed.
The California DOJ argument—and where it breaks down
Agencies across the region cited California DOJ guidance to justify full encryption. The argument doesn't hold up under scrutiny.
What agencies claimed
A 2020 California DOJ bulletin mandated protection of Criminal Justice Information (CJI) and Personal Identifying Information (PII) during radio transmissions.
What the DOJ actually required
The DOJ did not require wholesale encryption. Agencies like CHP and Palo Alto comply with the same requirements without encrypting all communications—they simply don't broadcast full PII over radio.

Impact on Bay Area journalism
The East Bay has strong local journalism—The Oaklandside, Berkeleyside, and the Mercury News—that depended on scanner access for breaking news. That access is now gone.
Response time lost
Journalists can no longer arrive at scenes as they develop—must wait for official notification
Single-source reporting
Police become the only source for initial incident information
Accountability reduced
Real-time verification of police statements no longer possible
Community monitoring ended
Organizations like Copwatch can no longer respond to incidents in progress
Alternatives that weren't tried
CHP and Palo Alto comply with the same DOJ requirements without full encryption. The East Bay chose the most restrictive approach without testing alternatives that work elsewhere in California.
The CHP Model
Officers read only partial information over radio; full details transmitted via cell phone or encrypted tactical channels.
Available but not adoptedDelayed Public Access
Baltimore model: 15-minute delay on public scanner access maintains transparency while preventing real-time exploitation.
Available but not adoptedPress Credentialing
San Antonio model: Credentialed media receive access to communications with certain channels disabled.
Available but not adoptedSplit Encryption (Seattle Model)
Dispatch channels remain open; only tactical channels encrypted.
Available but not adoptedThe domino effect
Berkeley shows what happens once a regional rollout reaches critical mass: holdouts face the "only open agency" pressure and have nowhere to point for political cover.
Why this matters for your region
- Regional coordination removes the per-agency veto points that local advocacy can work with—once a regional system standardizes on encryption, individual cities can't easily stay open.
- Each agency that encrypts strengthens the "criminal attention" argument for the next one, compounding the pressure.
- Fighting city-by-city after a regional rollout is nearly impossible—the fight has to happen at the regional governance level before it's too late.
- Organizing before encryption is announced is far more effective than trying to reverse it after the fact.
What happens next
The East Bay is fully encrypted. Reversing that is unlikely in the near term. What remains possible:
