8.16.010 - Findings.

The board of supervisors of the county makes the following findings:

A. The operation of aircraft at supersonic speeds above and in the vicinity of the county is causing more frequent, very loud, and increasingly intense, sudden and startling noises and ground level vibrations commonly known as "sonic booms."

B. Such sonic booms are causing physical injuries to persons, particularly persons engaged in hazardous or delicate activities, are damaging plaster, bricks and glass in buildings, are disturbing and detrimental to animals and livestock and do seriously frighten and alarm a large percentage of the citizens of the county.

C. No recognized or established "sonic corridors" travel over or near Trinity County.

D. Operation of supersonic aircraft above and in the vicinity of the county so as to cause such sonic booms are not reasonably necessary for national safety or defense, for convenience of air bases, nor for any other reason.

E. Enforcement of any prohibition against sonic booms is extremely difficult due to the lack of knowledge and information by local officials as to the identity of the individual piloting supersonic aircraft over or in the vicinity of Trinity County.

F. Information as to the identity of the individual or individuals piloting supersonic aircraft over or in the vicinity of Trinity County is available to or within the knowledge of the military and the Federal Aviation Administration.
