Editor's note— Ord. No. 11-15, § 1, adopted November 22, 2011, amended chapter 5 in its entirety to read as herein set out. Former chapter 5, §§ 4-11-501—4-11-505, pertained to loud parties, and derived from Ord. No. 95-21, §§ 1(IV.J-601)—(IV.J-605), 11-28-95.

Sec. 4-11-500. - Intent and purpose.

The intent of this chapter is to address inadequate supervision of parties and other types of events or gatherings of people on private property resulting in loud and/or unruly behavior that constitutes a threat to the peace, health, safety, and/or general welfare of the public. This chapter is also intended to address the problem of hosts of such gatherings who fail to ensure that alcoholic beverages are not served to, possessed by, or consumed by underage persons. Underage persons who consume alcoholic beverages are at a greater risk for injuries, vehicle collisions, addiction, truancy and making poor or dangerous choices, and hosts of parties, gatherings or events will be more likely to properly supervise or stop the consumption of alcohol by minors if they are held responsible for enabling or tolerating such conduct.

(Ord. No. 11-15, § 1, 11-22-11)

A responsible person or host need not have been issued a prior warning in order to be subject to the penalties for violation of this section. A responsible person or host shall be rebuttably presumed to have knowledge that an underage person was being served, was in possession of, or was consuming an alcoholic beverage at a party, gathering or event if the responsible person or host did not take all reasonable steps to prevent such activity from occurring. Reasonable steps include, without limitation: controlling the access to and serving of alcoholic beverages to underage persons, and monitoring the responsible, safe and lawful conduct of underage persons.

Sec. 4-11-504. - Cost; collection.

A. The Director of Public Safety shall provide the City Treasurer in writing with all information necessary concerning any police services fee and/or administrative fines imposed pursuant to this chapter. The City Treasurer may thereafter cause appropriate billing to be made to each responsible person or host. All fines and police services fees imposed pursuant to this chapter shall be due and payable to the City within the time period indicated by the City. However, if a timely appeal is requested pursuant to Section 4-11-505, the fines and fees shall be due and payable within 30 calendar days of a final decision on the appeal. The payment of fines and/or fees shall not constitute a waiver of a person's right to an administrative appeal.

B. The amount of any fines and fees imposed pursuant to this chapter shall be deemed a debt owed to the City. At its discretion, the City may pursue any and all legal and equitable remedies to collect unpaid fines and/or fees. Pursuit of one remedy does not preclude the pursuit of any other remedy. It is intended that responsible persons causing, maintaining and/or permitting the violation, and not the taxpayers, bear the financial burden of the City's enforcement efforts. Any person who fails to pay a fine or fee imposed under this chapter shall be liable in any proceeding brought by the City for costs incurred in securing payment of the unpaid amount, including, without limitation, administrative costs and attorney's fees. Liability for such costs shall be in addition to any penalties, interest and/or late charges imposed upon the unpaid fines and/or fees.

Failure of a person to request an administrative hearing within such time period, or failure of a person to appear at a scheduled hearing, shall constitute a waiver of the right to such a hearing.

B. Hearing procedures. If a written request for an administrative hearing is timely received by the Director of Public Safety, the City shall schedule a date for the hearing, and shall provide the person appealing with notice of the hearing date, time and location at least 20 days prior to the hearing date. The Director of Public Safety, or his or her designee ("hearing officer"), shall conduct the hearing in accordance with Section 4-13-308 of this Code. Challenges to the hearing officer's impartiality under Code of Civil Procedure § 170.1 shall be handled pursuant to Section 4-13-308D. The decision of the hearing officer shall be final.

C. Judicial review. If a decision is rendered in favor of the City, the responsible person may seek judicial review of the administrative decision by following the procedures set forth in Section 4-13-309.
