13.49.010 Findings and purposes.¶
A. The City Council finds as follows:
Unsupervised parties on private property where alcohol is consumed by minors are harmful to the minors themselves and to the communities where such parties are held.
Police ability to abate gatherings where alcohol is consumed by minors on private property will result in a decrease in abuse of alcohol by minors, physical altercations and injuries, neighborhood vandalism, and excessive noise disturbance thereby improving public safety.
Problems associated with such gatherings are difficult to resolve unless the Police Department has the legal authority to direct the host to disperse the group.
Control of large parties, gatherings or events on private property where minors are consuming alcohol is necessary when such activity is determined to be a threat to the peace, health, safety, or general welfare of the public.
Police officers frequently have been required to make calls to a location of a party, gathering, or event in order to disperse uncooperative participants, causing a drain of human effort and resources and in some cases, leaving other areas of the City with inadequate police protection.
Alameda County respondents to a 2006 BHCS AOD Youth Survey, Berkeley High School youth uniformly had significantly higher rates of alcohol use in the past 30 days (58%) when compared to their county-wide high school cohorts (33% and 35%), and 30% of the Berkeley High School respondents claimed that obtaining alcohol was "easy."
According to a 2004 Safer California Universities Study, 58.8% of UC Berkeley students consumed alcohol in the past 30 days, 49.8% of underage UC Berkeley students consumed alcohol in the past 30 days, 44.2% of UC Berkeley students who drank alcohol reported binge drinking in the previous two weeks, and 55.1% of UC Berkeley students surveyed thought it would be "very easy" to find an off-campus party if they wanted to drink alcohol.
B. The purpose of this Chapter is to address the problems identified above and protect the public health, safety and general welfare by enhancing the enforcement of laws prohibiting the consumption of alcohol by minors and reducing the costs of providing police services to parties, gatherings, or events requiring a response, by requiring hosts to ensure minors are not consuming alcoholic beverages.
