9.13.010 Findings And Intent¶
Minors often obtain, possess, or consume alcoholic beverages at parties held on private property under the control of a person who knows or should know of such conduct, but fails to stop it.
Underage consumption of alcoholic beverages poses an immediate threat to public health, safety and welfare in that it increases alcohol abuse by minors, physical altercations, violent crimes including rape and other sexual offenses, accidental injury, neighborhood vandalism, and excessive noise disturbance, all of which may require intervention by local law enforcement.
Law enforcement responses to disturbances involving underage consumption of alcoholic beverages at private parties frequently require the use of extensive resources. Further, when law enforcement personnel respond to disturbances at private parties it limits their ability to respond to other service calls in the community, thereby placing the community at increased risk. Law enforcement is not currently reimbursed for their expenses when called to a private party.
The prohibitions found in this chapter are reasonable and expected to deter the consumption of alcoholic beverages by minors by holding responsible persons who encourage, are aware of, or should be aware of, the illegal conduct yet fail to prevent it.
