Livermore ALPR fact sheet — checked 17 October 2026
Vendor / technology
Livermore Police says it uses Flock Safety technology, retroactive search and real-time hot-list alerts.
A second ALPR system
Policy 460.5.3 lets authorized users search ALPR information through Flock or Motorola, with separate query requirements for each.
Camera count — 2025
LPD's 2025 ALPR Annual Report lists 78 ALPR cameras. This is a dated count and can change.
Camera count — October 2026
The Flock portal lists 148 total active cameras: 75 Flock ALPR cameras and 73 non-Flock "ALPR capable" traffic cameras (updated 17 Oct 2026).
Retention
Policy 460.6: stored for a minimum of one year, then purged unless it is or may become evidence. The 2025 report says data is deleted within one year. The portal lists 365 days.
Search requirements
Before a Flock query, users must enter an offense type, a case or CAD number and a reason. All access is logged (Policy 460.5.3).
Collection scale — 30 days
1,201,553 unique vehicles detected, 238 LPD search sessions and 10,897 hotlist hits in the 30 days to 17 Oct 2026. Our calculation: about 5,000 vehicles recorded per search session.
Reported outcomes — 2025
225 stolen-vehicle hits, 23 felony-vehicle hits and 84 calls for service generated from ALPR information.
Flock contract ceiling
Resolution 2025-088 raised the Flock agreement to a not-to-exceed amount of $815,000. The Council approved it 5–0 on the 9 June 2025 Consent Calendar. This is a ceiling, not actual spending.
FY 2025–26 budget
$55,000 for project PS201722, Automated License Plate Readers, funded by Asset Seizure – County. This is a project appropriation, not total historical Flock spending.
Planned expansion
The City's project description says PS201722 will increase the number of ALPR systems, with remaining installations including the downtown core after the L Street Garage is completed.
Sharing list
The Flock portal lists the organizations granted access to Livermore's data. By our count, there were 340 on 17 Oct 2026.
Livermore's sharing limits
Policy 460.8 allows sharing only with California public agencies as permitted by law. It bars private, federal and out-of-state access except narrow, legally permitted functions.
California ALPR sharing restriction
Civil Code § 1798.90.55 says a public agency shall not sell, share or transfer ALPR information except to another public agency and only as otherwise permitted by law.
California DOJ interpretation
The California Attorney General's ALPR guidance states that federal and out-of-state law-enforcement agencies are not included in the statute's definition of a qualifying public agency, and says the restriction also applies to vendor-operated multi-agency ALPR databases.
Access logging requirements
California law requires ALPR operators that access or provide access to ALPR information to keep records of the date and time, query terms, user identity and affiliation, and purpose of access.
State enforcement is active
In October 2025, the California Attorney General sued El Cajon over alleged sharing of ALPR data with out-of-state law-enforcement agencies.
Decision-makers
Council members, districts, terms and office phone numbers were re-checked against the City Council page. The City Manager and Chief of Police office numbers were re-checked against their official pages. All checks done 17 Oct 2026.
What we could not verify
Unknown The records we have do not establish:
- Actual payments to Flock to date, as opposed to the $815,000 ceiling
- Which Motorola ALPR product Livermore uses, what it costs, and how its data is retained and shared
- How many of the 73 non-Flock "ALPR capable" traffic cameras actually read plates
- 2025 totals for plate reads, unique plates, searches, verified and false alerts, stops, arrests and recoveries
- What the "Flock AI" tool named in Policy 460.7 does in Livermore
- The staff, dispatch, IT and audit costs of running the program
We keep these on file as open questions and as public-records targets, not as claims.
What we are not claiming
We are not presenting the $55,000 appropriation or the $815,000 contract ceiling as Livermore's actual Flock spending. We are not claiming SignalTrace is deployed in Livermore. We are not claiming a court has ruled Livermore's specific ALPR deployment unconstitutional. We are not claiming all 148 cameras on the Flock portal are plate readers; the portal itself describes 73 of them as "ALPR capable" traffic cameras. We are also not claiming that any specific agency on Livermore's sharing list is receiving data unlawfully unless and until the underlying records and law support that conclusion.
Corrections in this update (17 October 2026)
- Policy 460 links. Links labelled "Policy 460" opened LPD's 2025 ALPR Annual Report. They now open Policy 460 itself.
- Retention. We had said Policy 460 sets a maximum of one year. The current policy, revised 9 September 2026, says a minimum of one year, then purge.
- Suspicion standard. We had said Policy 460 states that reasonable suspicion or probable cause is not required before using an ALPR. That sentence is not in the current policy, so we removed it.
- Council vote source. The June 9, 2025 minutes we link are the draft minutes in the June 23, 2025 agenda packet. We now label them that way.
- Camera count. We added the October 2026 portal count alongside the 2025 report's 78. An earlier, unsourced figure of 147 was never published here.
