Safeguarding
Trinity County
Aviation
Airport Management
 

Keeping our airport running is a challenging mix of funding, Federal regulations, and State permitting and safetly inspections. This section provides reference to documents that guide how our airports are maintained and improved.

Airport Funding

Keeping our airports running in Trinity County is always a challenge since the airports generate little direct revenue. Revenue is collected via parking fees, hangar rent, and encroachment permit fees. These revenues are normally use as matching fund for federal and state grants.

Our airport funding comes in two ways:

  • A yearly direct credit of $10,000 per airport from the California Division of Aeronautics fund. This funding was suspended in 2009 due to the State's spending problems. The outlook for 2010 funding is unknown.

  • The federal Airport Improvement Program. California's participation of matching 2.5% of federal aviation grants was suspended in 2009.
