The city council finds as follows:
A. 
The city of Pittsburg, pursuant to the police powers delegated to it by the California Constitution, has the authority to enact laws which promote the public health, safety and general welfare of its residents.
B. 
The occurrence of loud or unruly gatherings, or gatherings where persons under the age of 21 are present and where alcoholic beverages or cannabis are in the possession of, or are being consumed by, any person under the age of 21, is harmful to the community and the underage persons and is a public nuisance.
C. 
The city of Pittsburg has made numerous and substantial efforts to enforce underage drinking laws. Despite these efforts, alcohol use by youth remains a serious problem in the city, contributing significantly to the incidence of adolescent crime, addiction, truancy, driving under the influence of alcohol, and motor vehicle crashes involving alcohol and causing injury and/or death.
D. 
Cannabis use by youth is also a serious problem in the city. Frequent cannabis use during adolescence is associated with risk of cannabis addiction; impairments in attention, memory, and learning; and mental health issues. Cannabis use also poses risks to those on the road. In California, the percentage of driver fatalities testing positive for legal and/or illegal drugs increased from 43 percent in 2018 to 50 percent in 2019.
E. 
Residents have failed to prevent the occurrence of loud or unruly gatherings, including those where alcohol or cannabis is served to, consumed by or possessed by underage persons, which seriously disrupt neighboring residents' quiet enjoyment of their property.
F. 
Control of loud or unruly gatherings and control of gatherings where alcohol or cannabis is served to a minor is necessary because such activity is determined to be a public nuisance.
G. 
Persons held responsible for allowing, permitting or hosting loud or unruly gatherings or gatherings where alcohol or cannabis is served to persons under 21 will be more likely to properly supervise or stop such gatherings.
H. 
Law enforcement, fire, and other emergency response services personnel have responded, sometimes on multiple occasions, to loud or unruly gatherings or gatherings where alcohol or cannabis is served to, consumed by, or in the possession of underage persons, on private property, and responses to such gatherings result in a disproportionate expenditure of public safety resources of the city, which are supplemented by the general municipal taxes paid by residents and taxpayers, and such responses result in a delay of responses to regular and emergency calls to the rest of the city.
I. 
Problems associated with loud or unruly gatherings or gatherings where alcohol or cannabis is served, consumed by, or in the possession of underage persons are difficult to prevent or deter unless the city has the legal authority to issue an administrative citation or an administrative fine.
J. 
The intent of this chapter is to protect the public health, peace, safety and quiet enjoyment of residential property, and general welfare.
K. 
Section 25658 of the California Business and Professions Code makes it unlawful for a person under the age of 21 years to purchase or attempt to purchase or consume alcoholic beverages and makes it unlawful for any person to sell any alcoholic beverage to any person under the age of 21.
L. 
Section 26140 of the California Business and Professions Code prohibits the sale of cannabis to persons under the age of 21. (Those 18 years of age or older may use cannabis for medicinal use with a doctor's recommendation.)
M. 
The city council of the city of Pittsburg determines that this chapter is a reasonable and necessary means to protect and promote the health, safety, and general welfare of the youth and other residents of the city of Pittsburg.
