ALPR Program Overview

Executive summary

The available records show that the Board of Supervisors approved a proposed Flock Safety contract on February 25, 2025, followed by a 24-month agreement with a stated contract total of $85,500. Earlier records identify eight installed camera units at five general location groups; the July 27, 2026 email later produced with the focused response says two locations were still left to install.

The archive also contains training and access emails from 2023—well before the supplied 2025 contract—creating an unresolved question about the type of Flock subscription, network access, or other arrangement in place at that time.

Retention is another unresolved issue. The written CPRA response and Flock contract use a 30-day default, while the released Policy 473 says ALPR data downloaded to the server should be stored for a minimum of one year.

Program purpose in the records

The Board proposal describes intended uses including stolen or wanted vehicles, missing persons, warrants, investigations, and stolen property recovery. Policy 473 similarly limits the system to official law-enforcement business, though it states reasonable suspicion or probable cause is not required before using an ALPR.

General camera locations

The Sheriff’s Office identified Lake Camanche entrance/exit (two cameras), Shenandoah Road near Highway 49, Ridge Road and Highway 49 (two), Airport Road (two), and Ridge Road near Highway 88. Those descriptions account for eight camera units.

A July 27, 2026 Flock email says two locations were still left to install but does not identify either site. The archive therefore lists those two as unresolved rather than assigning them to a road or map point. A single-item August 10 request seeks their planned or current locations.

Key findings

• The Board approval packet is marked approved unanimously on February 25, 2025.
• The executed order form states an initial 24-month term, a $45,500 first-year subtotal, a $40,000 annual recurring subtotal, and an $85,500 contract total.
• Training and access rollout records date to 2023.
• Two external data-sharing records were released: Sacramento County and San Rafael.
• The released 30-day volume file contains 700,047 reads, averaging about 23,335 per day.
• The aggregate hotlist files contain 1,072 alerts.

Questions remaining

• What contractual or network arrangement supported the 2023 access and training?
• Does the one-year policy language apply to any server-side copy distinct from Flock’s 30-day cloud retention?
• Which California agencies were on the permitted-access list referenced in the response?
• Where are the two remaining installations referenced on July 27, and what are the installation, activation, and current statuses of all ten project locations?
• Did the County issue a substantive response to the July 30 policy-compliance notice or adopt any corrective policy changes?
