When any police officer responds to any loud party or similar event, and that police officer determines that the party or similar event violates Section 9.17.020 of this chapter, or that the party or event endangers the public peace, health, safety or general welfare, that police officer shall issue a written notice to the responsible person or persons to immediately discontinue the loud and unreasonable noise, or other activity which violates Section 9.17.020, and further give notice that a second response to that same location or address within a twenty-four hour period shall cause the responsible persons to be subject to liability for civil penalties amounting to the cost of services as defined in this chapter.
(Ord. 819-97 § 1)
If, after a written notice is issued pursuant to Section 9.17.030, a second response is necessary to the same location or address within a twenty-four hour period, all responsible persons shall be jointly and severally liable for civil penalties amounting to the cost of services as defined in this chapter, to a maximum of one thousand dollars.
(Ord. 819-97 § 1)
The police officer in charge at the scene is hereby authorized to immediately close and disperse any party or similar event for which a second response is required unless such officer determines that immediate closure would create an even greater threat to the public peace, health, safety or general welfare.
(Ord. 819-97 § 1)
The cost of services shall be collected in the manner described below:

Copies of the notice issued pursuant to Section 9.17.030 and of the incident report and any supplemental report shall be used by the Los Angeles County sheriff's department to compute the cost of services in connection with the second response and any further response that may be required. The Los Angeles County sheriff's department shall notify the finance department of the city of the proper amount, and the finance department shall bill the responsible persons.
B. 
The invoice shall notify the responsible persons that a hearing to present any evidence or argument challenging the amount of the invoice or liability therefor shall be available if a written request for such hearing is received by the office of the city manager within ten calendar days of the date the invoice is mailed. If no such written request is received within such ten-day period, the total invoice amount shall be immediately due and payable as provided in Section 9.17.040 of this chapter.
C. 
If a written request for hearing is received within such ten-day period, the city manager or his or her designee (who shall not have been involved in the underlying incident) shall conduct a hearing within twenty calendar days after receipt of the written request, at a date set by the city manager. Written notice of the hearing shall be mailed to the requester at least ten calendar days in advance of the hearing. The decision of the city manager, or his or her designee, shall be final, and the civil penalties imposed, if any, shall become immediately due and payable upon the mailing of notice of the decision.

A. 
The imposition of civil penalties pursuant to this chapter shall not prevent the imposition of any other civil or criminal penalties or remedies which may be available to the city.
