The Drone Integration and Zoning Act seeks to clarify the regulatory framework for unmanned aircraft systems (UAS) by redefining federal and local authority over airspace. A key provision amends federal law to exclude the area within 200 feet above ground level from the definition of "navigable airspace" for civil UAS operations, effectively creating a lower airspace zone for local regulation. The Federal Aviation Administration (FAA) is mandated to conduct rulemaking to update this definition and designate the area between 200 and 400 feet above ground level for its exclusive authority over civil UAS. The bill explicitly preserves the authority of State, local, and Tribal governments to issue reasonable time, manner, and place restrictions on civil UAS operating below 200 feet above ground level. These restrictions can include limitations on speed, prohibitions near schools or parks, and rules for specific times or events, provided they do not create a significant safety hazard. Furthermore, the FAA is prohibited from authorizing UAS operations below 200 feet over private property without the owner's permission, reinforcing property rights. For commercial drone operations, the FAA must establish a process to designate "authorized commercial routes," which cannot include any area below 200 feet above ground level. The legislation also preserves local zoning authority for the designation, placement, construction, or modification of unmanned aircraft take-off and landing zones . Local governments must act on applications for these zones within 60 days and cannot unreasonably discriminate among commercial operators or effectively prohibit their operations. While granting local control, the bill prohibits State, local, or Tribal governments from adopting laws that unreasonably or substantially impede the ascent or descent of UAS to navigable airspace, such as a complete ban on overflights. It also clarifies that certain federal preemption provisions for air carriers do not apply to civil UAS operations, and operators of civil UAS are excluded from the definition of an "air carrier." States are permitted to authorize intrastate carriage of property by commercial UAS operating solely within the immediate reaches of airspace and their lateral boundaries. Finally, the bill establishes a process for State, local, or Tribal governments to apply for the designation of "complex airspace" (above 200 feet with tall structures), allowing the FAA to delegate management responsibilities for such areas. It also mandates improvements to the Unmanned Aircraft Systems Traffic Management (UTM) plan, requiring collaboration with State, local, and Tribal governments and permitting the testing of their restrictions within the immediate reaches of airspace to ensure safe and efficient drone integration.
