Lake County presents draft drone policy for cannabis code enforcement; supervisors ask for clearer privacy limits and reporting

County Community Development staff presented a draft drone-usage policy to the Lake County Board of Supervisors on Oct. 12, describing a three-part approach intended to support code enforcement and evidence collection for suspected illegal cannabis cultivation.

Maria Turner, community development director, said the policy work was funded in part by Proposition 64 cohort 3 money and follows up on earlier satellite imagery and training. “We have developed a 3 part policy. The first policy is a policy on inspection warrants that outlines the process for assessing, privacy expectations, scope, and legal requirements ahead of our drone use. And then policy 2 is a drone operations policy ... And the 3rd policy is a records retention policy,” Turner said.

Marcus, a community development staff member, described the intended operational limits: launches from public vantage points, flights focused on remote parcels and reliance on the open-field doctrine where applicable. “We're not gonna be flying over people's properties. We're gonna have, suspicion before we go over,” he said, adding that drone use will generally be preceded by a determination that reasonable suspicion exists.

Marcus and Turner said drone imagery will usually be used to obtain inspection warrants and to improve officer safety and efficiency; boots-on-the-ground inspections remain the default for annual and compliance checks. “The purpose of the drone would be to ... get the evidence to get an inspection warrant,” Marcus said, and staff emphasized they will continue to use satellite imagery available through an MOU with the California Department of Fish and Wildlife.

Supervisors raised privacy and oversight questions. Supervisor Spatier asked the staff to explicitly prohibit enhanced identification technologies such as facial recognition and license-plate reading unless a warrant or specific legal authorization exists. “I'm just wondering if we can identify specifically, we're here to take pictures. We're not here to do facial recognition,” the supervisor said.

County staff responded that the drones purchased for the program lack facial-recognition capabilities. “The drones that we have purchased do not have, facial recognition, within it,” a staff member said, and Marcus reiterated that the county did not buy drones with enhanced identification features and that the program will focus on signs of cultivation — hoop houses, water tanks, fencing and other infrastructure — rather than identifying individuals.

Supervisors also requested periodic reporting to the board about drone use. One supervisor asked for an annual summary of drone deployments and the types of issues identified, without requiring property-level detail, to maintain oversight of a sensitive technology. Staff agreed to consider clearer statements of purpose at the beginning of the policy and to add reporting language.

Public commenters asked practical operational questions. Angela Emerald asked about launch ranges and how staff would operate where parcels are surrounded by private land; staff said a “public vantage point” can include easements, roadways or open hillsides and that pilots would tailor operations to minimize overflight of adjacent private parcels.

Turner said the county has trained four Community Development staff as FAA-licensed remote pilots. Staff stressed the policy is intended to avoid the legal pitfalls some jurisdictions have faced by relying solely on drone footage to take enforcement action.

The item was presented for discussion; no policy was adopted and no vote was taken. Staff will return with refinements to the draft language, including clearer statements of purpose, explicit prohibitions or limits on identification technologies, and reporting or auditing language for board review.
