Pleasanton ALPR fact sheet — checked 19 October 2026
Vendor / technology
Pleasanton Police says it has used fixed ALPR cameras since 2019 and now uses a Flock system exclusively, with retroactive search and real-time hot-list alerts.
Camera count — 2025 agreement
The City's 9 July 2025 supplemental memo corrected the staff report from 54 cameras to 38 ALPR cameras.
Camera locations — September 2026
The ALPR page lists 34 current or planned camera locations as of 24 Sept 2026.
Camera count — October 2026
The Flock portal lists 47 total cameras, described as "LPR and other cameras" (updated 19 Oct 2026).
Retention
Policy 446.5: a maximum of 30 days, then purge unless the data is or may become evidence. The ALPR page and the portal both say 30 days.
Suspicion standard
Policy 446.4(b): "reasonable suspicion or probable cause is not required before using an ALPR."
Search requirements
Every detection browsing inquiry must be documented with a case or incident number and/or a reason, and access is logged by name, date and time (446.6).
Audits
At least twice a year, an audit of at least 10 PPD searches and 10 outside-agency searches, documented in a memo to the Chief of Police (446.7).
Collection scale — 30 days
762,704 unique vehicles detected, 229 search sessions and 3,213 hotlist hits in the 30 days to 19 Oct 2026. Our calculation: about 3,300 vehicles recorded per search session.
Flock contract ceiling
A five-year agreement, not to exceed $639,760, approved 5–0 on the 15 July 2025 Consent Calendar (Item 15). This is a ceiling, not actual spending.
Former Vigilant federal-access error
The City says the San Diego Sector Border Patrol was misclassified as a state agency and stayed eligible to search data from three Vigilant locations until 8 July 2026.
Did Border Patrol actually search?
The City cannot say. The former Vigilant system did not log outside-agency searches.
Sharing list
The Flock portal lists the organizations granted access to Pleasanton's data. By our count, there were 160 on 19 Oct 2026.
Pleasanton's sharing limits
Policy 446.8: sharing agreements only with California law enforcement agencies. Policy 446.10: no sharing for federal immigration enforcement (ICE, CBP) or for investigating abortion or gender-affirming care lawful in California.
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 Attorney General's ALPR guidance excludes federal and out-of-state law-enforcement agencies from the statute's definition of a qualifying public agency.
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
Names, titles and districts were re-checked against the City Council page, which lists one office line, (925) 931-5001. The Mayor, District 1 and District 3 seats are on the 3 November 2026 ballot. All checks done 19 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 $639,760 ceiling
- How many of the portal's 47 cameras read plates, and how they map to the 34 listed locations
- Annual totals for plate reads, unique plates, searches, verified and false alerts, stops, arrests and recoveries
- Whether the San Diego Sector Border Patrol ever searched Pleasanton's former Vigilant data
- How the City defines the regions its sharing is limited to, and which listed entities it treats as law enforcement agencies
- 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 $639,760 contract ceiling as Pleasanton's actual Flock spending. We are not claiming Pleasanton's current Flock system has been proven to share data with federal or out-of-state agencies. We are not claiming Border Patrol actually searched the former Vigilant data; the City says the necessary logs do not exist. We are not claiming all 47 cameras on the Flock portal are plate readers; the portal describes them as "LPR and other cameras." We are not treating the older 2023 two-year Vigilant retention figure as current. We are also not claiming that any specific agency on Pleasanton's sharing list is receiving data unlawfully unless and until the underlying records and law support that conclusion.
Corrections in this update (19 October 2026)
- Camera count. We had described a "54-camera replacement program." The City's 9 July 2025 supplemental memo corrected the staff report to 38 ALPR cameras. We now cite 38, and add the September 2026 location list (34) and the October 2026 portal count (47).
- Cameras per mile. Our "one ALPR for every 4.0 miles (7,007 yards)" used 54 cameras. At 38 cameras it is one for every 5.7 miles (9,958 yards).
- Contract source. The $639,760 figure was sourced to Pleasanton Weekly. It now links to the City's own agenda, supplemental memo and minutes. The amount was correct.
- Council terms. We listed "November 2026" and "November 2028." The City Council page gives no end dates. We now list 2026 or 2028, based on which seats are on the City's 2026 ballot.
- Policy source. We now cite Policy 446 in the 9 July 2026 policy manual directly, rather than relying only on the City's July 2026 memo.
