Existing law, the State Aeronautics Act, governs various matters relative to aviation in the state, and authorizes the Department of Transportation to adopt, administer, and enforce rules and regulations for the administration of the act.
This bill, the Advanced Air Mobility Infrastructure Act, would require the department, in coordination with specified agencies, to include advanced air mobility, as defined, in the next update to the California Transportation Plan prepared after January 1, 2027, and to establish a statewide working group to facilitate ongoing collaboration to explore California’s role as a leader in the development and implementation of advanced air mobility, as specified. The bill would prohibit its provisions from being construed to (1) interfere with or suspend the authority of the Federal Aviation Administration or any other federal department or agency, or state zoning laws or regulations, as specified, or (2) limit or interfere with the jurisdiction, authority, rights, or responsibilities of any airport sponsor or operator, as specified.
The people of the State of California do enact as follows:
SECTION 1.
The Legislature finds and declares all of the following:(a) If developed and deployed at scale, the development of advanced air mobility can provide economic and environmental benefits to the state and the nation.
(b) The use of advanced air mobility can aid in California’s progress toward its statutory renewable energy and climate mandates.
(c) Diversity in technologies lowers overall costs. Advanced air mobility technology adds diversity to the state’s transportation portfolio.
(d) The development of advanced air mobility presents an opportunity to California by providing a tremendous opportunity for economic growth, including the development and preservation of a skilled and trained construction workforce to carry out projects and long-term job creation, all while improving mobility and accessibility for all Californians.
(e) Advanced air mobility improves multimodal transportation and access to destinations by providing transportation opportunities that improve access to jobs, services, educational opportunities, and emergency and medical services.
(f) Advanced air mobility will allow all Californians to traverse densely populated areas in a matter of minutes instead of hours, expanding accessibility while reducing traffic congestion on our roadways.
(g) Investment in advanced air mobility can offer career pathways and workforce training in clean energy development. Advanced air mobility will provide additional blue collar industrial work opportunities and support apprenticeship opportunities for a diverse labor pool.
