California Aviation System Plan
California Aviation System Plan
The California Public Utilities Code Sections 21701- 21705 establish the requirements for the California Aviation System Plan (CASP). The CASP examines aviation activity and air transportation issues in California and includes state and regional planning elements. The CASP includes airports in the federal National Plan of Integrated Airport Systems, and other public use airports as designated by Caltrans.
The 2026 CASP is currently under development. In 2025, an advisory committee was established to support the 2026 CASP development. A draft of the 2026 CASP is expected to be available for public comment in late 2026.
The 2020 CASP represents a comprehensive progression for all California airports to evaluate aviation and contribute to the California Transportation Plan (CTP) 2050.
