9.22.020 - Findings and purpose.¶
The city council finds and declares as follows:
A. Unruly gatherings, including but not limited to those where alcohol is consumed by underage persons, pose a hazard to public health, safety, the quiet enjoyment of property and the general welfare.
B. Gatherings at which underage persons and/or others consume alcoholic beverages may result in physical altercations, violent crimes including sexual offenses, automobile accidents, neighborhood vandalism and excessive noise disturbance.
C. Unruly gatherings frequently require a response by numerous law enforcement personnel, limiting their ability to respond to other service calls in the city.
D. Unruly gatherings are often the result of inadequate, or a lack of, adult supervision.
E. It is the purpose and intent of this chapter to protect the public health, safety and general welfare by reducing the occurrence of inadequately supervised and unruly gatherings, by holding persons responsible who allow, encourage, are aware of or should be aware of such gatherings, including but not limited to those where alcoholic beverages are consumed by underage persons.
F. It is further the purpose and intent of this chapter that the city deter persons from allowing unruly gatherings by assessing administrative penalties against such persons.

A. A person who has been issued an administrative citation pursuant to this chapter may contest the citation by filing a written appeal on a city-approved form with the city manager within ten (10) calendar days from the date of the citation. The basis for the appeal must be specified in detail on the appeal form. There shall be no filing fee for the appeal, however, a deposit in the amount of the citation must be paid at the time the appeal is filed. If the citation is dismissed as a result of the appeal hearing, the deposit shall be returned to the appellant within thirty (30) days from the date of the written appeal decision.
B. Failure of the city manager to receive a timely appeal constitutes a waiver of the right to contest a citation; in this event, the citation is final and binding.

The hearing shall be conducted by an independent and impartial hearing officer.

E. Failure of an appellant to appear at the scheduled hearing shall constitute the appellant's waiver of the right to appeal and a forfeiture of the citation amount deposited at the time the appeal was filed.
F. Appeal hearings are informal, and formal rules of evidence and discovery do not apply. The city bears the burden of proof to establish, by a preponderance of evidence, that the appellant conducted, hosted, permitted or allowed an unruly gathering. The officer issuing the administrative citation and/or submitting the written statement of facts shall not be required to appear at the hearing. The hearing officer shall accept testimony by declaration under penalty of perjury relating to the commission of the offense, as set forth in the issuing officer's statement of facts, and shall consider any other relevant evidence concerning the commission of the offense that the city manager may present at the hearing. The hearing officer shall also take the testimony of the appellant, and/or his or her witnesses, and will consider any other credible relevant rebuttal evidence the appellant may wish to present. The appellant may represent himself or herself or be represented by anyone of his or her choice, including counsel, at his or her sole expense. The appellant may bring an interpreter to the hearing at his or her sole expense.
G. The hearing officer shall make findings based on the record of the hearing, and shall prepare a written decision, based on those findings, to either uphold or dismiss the citation. A copy of the written decision shall be served on the appellant by first class mail within ten (10) days after the hearing. If the citation is dismissed, the city shall refund the amount of the citation deposit to the appellant within thirty (30) days from the date of the decision.
H. The decision of the hearing officer is final and conclusive, subject only to review by the superior court in accordance with the time limits set forth in Government Code Section 53069.4 and/or Code of Civil Procedure Section 1094.6.
