Nevada County’s research pass read the published policy manuals of all three city police departments, the Sheriff’s military equipment policy and 2025 report, Grass Valley’s Flock Safety order form, the Sheriff’s environmental notice for a reader, Truckee’s equipment list and annual summary, and the 2021 civil grand jury report on body cameras. The Sheriff’s policy index and the county’s daily newspaper could not be read by our tools on this pass and remain open.
What's in use here
Grass Valley's policy describes a second reader system, Motorola Vigilant cameras on one parking-enforcement vehicle, with data kept up to one year. The department's August 2026 suspension statement covers "fixed-point ALPR readers within our City limits" and does not mention this vehicle-mounted system.
The Sheriff's Office entered a $78,500 twelve-month Flock Safety pilot in March 2023 under Board Resolution 23-142, according to a May 2024 Board resolution that authorized an environmental notice for a camera at Highway 49 and Tyler Foote Road. The camera count, the agreement after the pilot, and the sharing list are not in the records we fetched.
Truckee Police says it uses Flock Safety license plate readers, with data purged by the vendor after 30 days. Its policy bars sharing for federal immigration enforcement and names Immigration and Customs Enforcement and Customs and Border Patrol.
Grass Valley's Flock Safety order form covers 25 cameras over five years at $316,550 with 30-day retention. On August 11, 2026 the police department said it would "indefinitely suspend our use of fixed-point ALPR readers within our City limits, exercising our ability to cancel our contract with Flock Safety."
The Sheriff's 2025 military equipment report lists four Skydio X10 drones in a program the Board approved in 2024, and states an intention to seek approval for DJI Avata drones that "will fly in smaller environments such as residences."
Truckee Police's 2026-27 military equipment list records four DJI drones, three of them at or nearing end of life. The 2025-26 annual summary says drones were deployed for searches, collision mapping, and "as a situational awareness resource during community events."
The county accepted a $123,000 federal body-camera grant for the Sheriff's Office in 2018, noting a $463,079 county match, and the office issued a request for proposals in January 2021, according to the civil grand jury. The contract that followed is not in a record we fetched.
Nevada City Police's Policy 339 governs its public-area video cameras. The chief told the City Council in February 2026 that the city uses six Flock Safety live-feed cameras in the Commercial Street area, not license plate readers, according to The Union.
Who runs it
The agency is the accountability unit: who voted, whose policy applies, and who answers a records request.
| Agency | Jurisdiction | SB 34 policy | Systems |
|---|---|---|---|
| Nevada County Sheriff's Office | Nevada County | — | 3 |
| Grass Valley Police Department | City of Grass Valley | On file | 2 |
| Truckee Police Department | Town of Truckee | Posted | 2 |
| Nevada City Police Department | City of Nevada City | — | 1 |
| 4 agencies on record. A jointly run system counts against each of its operators, so this column is not a county total. "Posted" means the policy is published where the law requires it. "On file" means we hold the document. "Not posted" and "not found" mean we could not find it on the agency's own website on the date shown; they say nothing about how the system is used. An agency with a dash has not been checked, which is not a finding. | |||
