Upon the initial response of the police department to any disturbance involving loud, unnecessary and unusual noise, the chief of police may, in lieu of or in addition to taking other action authorized by law, give notice to the person or persons in actual or apparent control of the activity creating the disturbance, or to the person or persons in actual or apparent control of the property or premises wherein the disturbance has occurred, or both, that liability may be imposed upon the person or persons receiving such notice for the costs to the city of any subsequent response by the police department in connection with any continuation or resumption of such disturbance. Such notification shall be in such form as may be approved by the chief of police. The costs of any subsequent response shall be assessed to the person or persons receiving such notice and shall include all costs reasonably incurred by the city in providing law enforcement services and equipment at the scene of the disturbance, including the cost or value of the time expended by police department personnel in making any subsequent response. The method of computing such costs shall be established by the chief of police and approved by the city council. The finance department shall invoice such costs to the person or persons liable therefor under this chapter, and such costs shall constitute a debt to the city and be collectible by the city in the same manner as in the case of an obligation under a contract; provided, however, that in no event shall a person's liability hereunder exceed $1,000 for any single subsequent response.
(Ord. 1515)
If a minor is in actual or apparent control of the activity creating the disturbance, or is in actual or apparent control of the property or premises wherein the disturbance has occurred, and, following notification, a subsequent response by the police department is made in connection with any continuation or resumption of such disturbance, then the acts or omissions of such minor shall be imputed to the parent or guardian having custody and control of the minor for all purposes of imposing liability for costs hereunder, and the parent or guardian shall be jointly and severally liable with the minor for all costs resulting there from. The liability imposed by this section shall be in addition to any other liability imposed by law.
