9.06.020 Purpose and intent.

The operation of unmanned aircraft systems (herein known as “UAS”) can pose a hazard to piloted aircraft in flight and to persons and property on the ground. In addition to safety concerns, UASs also raise serious privacy and trespass concerns. It is therefore the intent of this ordinance to impose community-based safety requirements on the operation of model aircraft and to restrict the operation of all UASs consistent with federal aviation rules and state law in order to mitigate such risks, to respect privacy and trespass issues, and to protect the public from the hazards associated with their operation. (Ord. 623, 2017)
