The purposes of this chapter are:

A.

To protect the public health, safety and general welfare;

B.

To promote the reduction of underage drinking by imposing a civil fine on persons responsible for loud or unruly gatherings where alcohol is consumed by, served to or in the possession of underage persons;

C.

To facilitate the enforcement of laws prohibiting the service to, consumption of or possession of alcoholic beverages by underage persons; and

D.

To offset the municipal costs associated with providing fire, police, and other emergency services to loud or unruly gatherings by imposing a civil cost recovery penalty upon social hosts and/or landowners who conduct or allow such loud or unruly gatherings to occur on their premises, at their residences, or at rented facilities where alcoholic beverages are served to, consumed by, or in the possession of underage persons.

9.42.030 - Legislative findings.

The board of supervisors finds as follows:

A.

The county of Alameda, 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 on private property where alcoholic beverages are served to, consumed by or in the possession of underage persons is harmful to the underage persons themselves and is a threat to the public health, safety, or quiet enjoyment of residential property and the general welfare;

C.

The county of Alameda has made numerous and substantial efforts to enforce underage drinking laws; yet, despite these efforts, alcohol use by youth remains a serious problem in the county, contributing significantly to the incidence of adolescent crime, addiction, sexual assault, truancy, driving under the influence of alcohol, and motor vehicle crashes involving alcohol and causing injury and/or death;

D.

Underage persons often obtain alcoholic beverages at gatherings held at private residences or at rented residential and commercial premises that are under the control of a person who knows or should know of

the service to, possession by, and/or consumption of alcohol by underage persons. Persons responsible for the occurrence of loud or unruly gatherings on private property over which they have possession or control have failed to ensure that alcoholic beverages are not served to, consumed by or possessed by underage persons at these gatherings;

E.

Residents have failed to prevent the occurrence or reoccurrence of loud or unruly gatherings, including those where alcoholic beverages are served to, consumed by or possessed by underage persons, on private property, which seriously disrupts neighboring residents' quiet enjoyment of their property;

F.

Control of loud or unruly gatherings on private property where alcoholic beverages are served to, consumed by or in the possession of underage persons is necessary when such activity is determined to be a threat to the peace, health, safety, or general welfare of the public;

G.

Persons held responsible for abetting or allowing loud or unruly gatherings where alcohol is served to, consumed by or in the possession of underage persons will be more likely to properly supervise or to stop such conduct at gatherings held on property in their possession or under their control;

H.

In the past and present, law enforcement, fire and other emergency response services personnel have responded and are required to respond, sometimes on multiple occasions, to loud or unruly gatherings on private property at which alcoholic beverages are served to, consumed by or in the possession of underage persons, and responses to such gatherings result in a disproportionate expenditure of public safety resources of Alameda County, which are underwritten by general county taxes paid to the county by its taxpayers and residents, and also result in a delay of sheriff responses to regular and emergency calls to the rest of the county;

I.

Problems associated with loud or unruly gatherings at which alcoholic beverages are served to, consumed by or in the possession of underage persons would be greatly deterred and alleviated if the Alameda County sheriff's office has the additional legal authority to issue a civil citation for a civil fine and/or a civil citation for the cost of public safety response;

J.

The intent of this chapter is to protect the public health, safety, quiet enjoyment of residential property, and general welfare, rather than to punish. Persons who actively or passively aid, abet, or allow loud or unruly gatherings shall be held liable for the nuisances created by such gatherings, the civil fine(s) for such violations and the costs associated with responding to such gatherings;

K.

Section 25658 of the state of California Business and Professions Code makes it unlawful for a person under the age of twenty-one (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 twenty-one (21) years;

L.

According to local, state and federal surveys, alcohol is overwhelmingly and consistently the most widely used drug at all adolescent age levels. A child who begins alcohol use prior to age fifteen (15) is four times as likely to experience alcohol dependence than one who refrains from alcohol use until age twenty (20) or older;

M.

This county of Alameda board of supervisors therefore 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 county of Alameda.

9.42.050 - Prohibition of loud or unruly gatherings where alcohol is served to,…

Except as permitted by Article 1, Section 4, of the California Constitution, no person shall knowingly suffer, permit or host a gathering at his or her place of residence or other private property, place or premises or host a gathering at a public place under his or her control where two or more persons under the age of twenty-one (21) are present, where the gathering is loud or unruly and alcoholic beverages are in the possession of, being consumed by, or served to any underage person. In addition to any fine or penalty that may be imposed by law, any violation of the provisions of this chapter shall be subject to a civil fine or penalty as provided herein. The following fines or penalties apply to this chapter:

A.

Violation(s)/Civil Fine(s). It shall be a civil violation for a person to knowingly conduct or allow a loud or unruly gathering where alcohol is served to, consumed by or in the possession of an underage person or persons on premises owned by the person responsible for the event, on premises rented by or to the person responsible for the event, on premises where the person responsible for the event resides or on premises where the person responsible for the event is in control of such premises during the loud or unruly gathering. The sheriff, at his or her discretion, may immediately issue a citation for this civil violation upon

evidence of the violation. There is no requirement of a first warning in order for the sheriff to issue this civil citation.

1.

Civil Fine. A first violation of this section shall result in a citation with a seven hundred fifty dollar ($750.00) fine. A second violation shall result in a citation with a one thousand five hundred dollar ($1,500.00) fine. A third or subsequent violation shall result in a citation with a two thousand five hundred dollar ($2,500.00) fine.

2.

The sheriff shall give notice of a violation of this section by issuing a citation to any and all responsible persons identified by the sheriff within thirty (30) days of the violation. The citation shall also give notice of the right to request an administrative hearing to challenge the validity of the citation and the time for requesting that hearing (see Section 9.42.055).

3.

The civil fine prescribed in subsection (A)(1) of this section is in addition to any imposition of civil penalty for cost recovery for public safety responses that may be assessed pursuant to subsection B of this section.

4.

In the event that the responsible person who is in violation of this section is a juvenile, then the juvenile and the parents or guardians of that juvenile will be jointly and severally liable for the civil violation.

B.

Imposition of Civil Penalty for Cost Recovery for Public Safety Responses. In addition to any civil fine imposed for violation of this section, when any loud or unruly gathering where alcohol is served to, consumed by or in the possession of underage person(s) occurs on private property and a public safety officer at the scene determines that there is a threat to the public peace, health, safety or general welfare, the public safety officer shall give to the person(s) responsible for the event warning that a second or follow up violation of this section on the same date or on any later date will result in his/her/their liability for the cost of providing public safety services (i.e., fire, ambulance, sheriff, and other emergency providers). The requirement of a first warning does not limit the ability of public safety personnel to issue a civil citation for the imposition of civil penalties for cost recovery on the same day that the warning is given if the warning does not end the loud or unruly gathering. The cost recovery for public safety responses shall be separate and distinct from a citation and fine for a civil violation described in subsection A of this section.

1.

The amount of cost recovery under this subsection shall be calculated pursuant to Section 9.42.040(G) of this chapter.

In the event that the responsible person who is in violation of this section is a juvenile, then the juvenile and the parents or guardians of that juvenile will be jointly and severally liable for the imposition of civil penalties for the cost of providing public safety services.

3.

Civil cost recovery penalties will not be imposed in those situations where those present at the gathering call for emergency services for an actual emergency at the premises.

C.

Administrative Penalties. Taking into consideration the age and/or financial ability of the responsible person(s) to pay, the hearing officer may impose, in addition to or in lieu of civil fines and/or cost recovery penalties in subsections A and B of this section:

1.

Community service work on behalf of the county;

2.

Training or classes that are relevant to the legislative purpose and findings of this chapter as set forth in Sections 9.42.020 and 9.42.030; and/or

3.

Failure to complete the administrative penalties as directed will result in that penalty or penalties being converted to civil fines and/or cost recovery penalties as set forth herein without further right to appeal.

(Ord. 2007-25 § 1 (part))

9.42.055 - Hearings on the imposition of civil fine and/or imposition of civil penalty…

A.

Administrative Hearing. Any person subject to a civil fine pursuant to Section 9.42.050(A) or subject to a civil cost recovery penalty for public safety responses pursuant to Section 9.42.050(B) shall have the right to request an administrative hearing within forty-five (45) days of the issuance of a citation for a civil violation of this chapter (Section 9.42.050(A)) and/or the issuance of a citation for the imposition of civil cost recovery penalties for a public safety response as specified in this chapter (Section 9.42.050(B)) pursuant to the authority granted to the board of supervisors by Government Code Section 25845, subdivision (i). To request such a hearing, the person requesting the hearing shall notify the Alameda County clerk of the board of supervisors in writing within forty-five (45) days of the issuance of the citation.

The Alameda County clerk of the board of supervisors shall refer any request for a hearing under Section 9.42.050(A) and/or Section 9.42.050(B) to a neutral hearing officer. The neutral hearing officer shall conduct a hearing on the matter within ninety (90) days of the request for the hearing unless one of the parties requests a continuance for good cause. The hearing officer shall render a decision within thirty (30) days of

the conclusion of the hearing. Either party may appeal the decision of the hearing officer pursuant to the requirements set forth in subsection B of this section. The Alameda County administrator's office may contract for the services of a neutral hearing officer as appropriate and the hearing officers may be compensated for their services. The costs of the administrative hearing shall be assessed to the responsible person in addition to any other fines and penalties in the event that the citation is upheld.

B.

Appeal from Decision of Neutral Hearing Officer. The person upon whom a civil fine is imposed pursuant to Section 9.42.050(A) and/or upon whom a civil cost recovery penalty is imposed pursuant to Section 9.42.50(B) may appeal the decision of the neutral hearing officer. The county may also appeal the decision of the neutral hearing officer. No appeal can lie unless the party filing the appeal has first properly requested and obtained a hearing under Section 9.42.055(A).

The appeal must be filed in writing within twenty (20) days after service of the final decision issued by the hearing officer pursuant to California Government Code Section 53069.4, subdivision (b). The procedures outlined in Government Code 53069.4 shall apply.

(Ord. 2007-25 § 1 (part))

9.42.060 - Civil fine and civil penalty for cost recovery for public safety…

The amount of a civil fine and/or civil cost recovery penalty for public safety responses shall be deemed a debt owed to the county by the person(s) found in violation of Section 9.42.050 and therefore liable for a fine under Section 9.42.050(A) and/or penalties under Section 9.42.050(B), and, if that person is a juvenile, then also his/her parents or guardians. Any person owing such fine and/or penalties shall be liable in an action brought in the name of the county for recovery of such fine and/or penalties. These recovery costs may include reasonable attorney fees incurred in the action if the county prevails, as the county reserves the right to seek to recover reasonable attorney fees, on a case by case basis, pursuant to California Government Code Section 25845, subdivision (c). In those cases in which the county seeks to recover reasonable attorney fees, the other party may likewise do so. All such costs recovered by the county pursuant to this chapter shall be placed in the sheriff's unincorporated area trust fund.
