13.100.020 - Findings, Purpose and Intent.

The Board of Supervisors finds and declares as follows:

A.

As a legal subdivision of the State of California charged with governmental powers authorized by Article XI of the California Constitution, the County of Los Angeles (County) has broad and plenary authority to regulate with regard to municipal affairs within its unincorporated area, subject only to restrictions and limitations provided by its charter, by State law, and by the United States Constitution.

B.

Los Angeles County recognizes that the consumption of alcoholic beverages by minors is a persistent problem, and the costs and consequences of underage drinking affect virtually everyone. According to a 2016 study by the American Medical Association, alcohol continues to be the most abused substance for American youth. And, although alcohol consumption and binge alcohol use among adolescents in Los Angeles County has decreased over recent years, the rates remain high.

C.

Underage drinking is a public health concern for youth in the County because the effect of alcohol on an adolescent's brain can result in severe impairment of biological, psychological, and social functioning. Such impairment can increase the likelihood of engaging in unprotected sex, driving under the influence, and other reckless and dangerous behaviors. Underage drinking can also lead to low self-esteem, depression, and poor concentration, which can increase school dropout rates, and foster a reliance on alcohol for social interactions throughout adulthood.

D.

The County recognizes that the possession or ingestion of cannabis by underage persons for other than medical purposes, as well as its provision to those youth, is of equal concern.

E.

The implementation of a social host ordinance can reduce access and availability of alcohol and cannabis to minors, and thus remove opportunities for minors and underage persons to engage in drinking alcohol or ingesting cannabis.

F.

In California, more than 40 cities and counties have adopted some form of social host laws. These ordinances have successfully reduced the number of parties serving alcohol to minors. Moreover, cities and counties have found that passage of social host laws led to a decrease in alcohol use among youth and a very low rate of party host citations - indicative of such laws' deterrent effect. Recently, several jurisdictions have amended their existing social host laws to include cannabis.

G.

In Los Angeles County, the cities of the Palos Verdes Peninsula have recently adopted social host ordinances: Palos Verdes Estates; Rancho Palos Verdes; Rolling Hills Estates; and Rolling Hills (collectively, "Peninsula Cities"). The Peninsula Cities share boundaries with a small region of unincorporated County areas known as "Academy Hill," "Westfield," and "the Estates." This ordinance will ensure conformity of laws on the Palos Verdes Peninsula, where the Los Angeles County Sheriff's Department patrols most of the region.

H.

This chapter's purpose is to ensure public health, safety, and general welfare; discourage and decrease underage drinking and ingestion of cannabis by imposing a civil fine on persons responsible for gatherings where alcoholic beverages and/or cannabis are consumed or ingested by, or served to, underage persons; and facilitate the enforcement of laws prohibiting the service to, and consumption or ingestion of, alcoholic beverages and/or cannabis by underage persons. It is not the intention of this Chapter to hold persons responsible for the provision or facilitation of cannabis to persons who possess and/or consume cannabis for medical purposes pursuant to State law.

I.

It is the intent of this Board that this Chapter be implemented in the unincorporated County areas known as "Academy Hill," "Westfield," and "the Estates."
