California Aviation System Plan

The CASP Project (Project) has been completed for each subject area below:

  • Policy and Regulations
  • Infrastructure and Safety
  • Economics and Funding
  • Future Trends and Needs
  • Mobility and Access
  • Land Use and Sustainability


The CASP was first introduced in 1989 when codified in California Public Utilities Code section 21702 but has not kept pace with California transportation planning. Likewise, FAA Advisory Circular 150/5070-7, The Airport System Planning Process, has evolved without an updated approach in California. The purpose for updating the CASP is to better align aviation planning from the perspectives of both the FAA and the California Department of Transportation (Caltrans) to positively demonstrate that aviation is an integral part of California’s multimodal transportation system.

Accessibility Assistance: The CASP file has been processed for accessibility and ADA compliance. For additional assistance, please contact us at (916) 654-4848 or visit

CASP 2020 presents a comprehensive progression for all California airports to evaluate aviation and contribute to the California Transportation Plan (CTP) 2050.
