The committee accepted the surveillance-technology impact report for the Smart Tree Inventory, a one-time vehicle-mounted LiDAR and photography survey processed with AI that produced a roughly 16,000-tree digital inventory and 3-D models. Staff said imagery is focused on trees, hosted by a vendor, and not publicly accessible; incidental capture of people is possible but access is limited to authorized users.
