A. The unlawful fireworks use or a fireworks gathering is in violation of this chapter; and

B. The responsible person(s) may be charged for any response costs incurred for subsequent responses to the property for unlawful fireworks use or a fireworks gathering in violation of this chapter within a twelve-month period.

This warning will be given to all identified responsible persons at the time of the first response to unlawful fireworks use or a fireworks gathering in violation of this chapter where a citation is issued for violation of this chapter before assessing response costs pursuant to this section for subsequent responses within a twelve-month period following issuance of the citation. Within thirty calendar days of the initial citation, an additional written warning shall be transmitted via certified mail to the record owner of the residence or private property as shown in the records of the Sonoma County assessor’s office.

When a peace officer or code enforcement officer responds to unlawful fireworks use or a fireworks gathering in violation of this chapter at a residence or other private property within the city within twelve months of a citation and warning given to responsible person(s) at the same property, and an officer issues a second or subsequent citation pursuant to this chapter, all responsible persons shall be jointly and severally liable for the city’s response costs concerning such second or subsequent unlawful fireworks use or a fireworks gathering that exists in violation of this chapter, but only to the extent that such responsible person(s) concerning the first citation at such property remain responsible person(s) for the second or subsequent citation at such property.
