In addition to any fine imposed under Section 10.36.050, any person who violates this chapter shall be liable and responsible for a civil penalty of one thousand dollars ($1,000.00) for each day such violation occurs. The city may recover such civil penalty by either civil action or administrative citation. Such penalty shall be in addition to all other costs incurred by the city, including, without limitation, the city’s staff time, investigation expenses, and attorney’s fees.
B. In addition to any fine imposed under Section 10.36.050, and any civil penalty imposed under subsection A of this section, any person operating a vehicle in violation of this chapter shall be liable, and shall indemnify and hold the city harmless, for any damage or liability to public facilities arising out of or related to any such violation. Such liability shall be in addition to all other costs incurred by the city, including, without limitation, the city’s staff time, investigation expenses, and attorney’s fees. The city may recover such liability, costs, and fees by either civil action or administrative citation.
C. Where the city proceeds by administrative citation in collecting either the civil penalty imposed by subsection A of this section or the liability for damage caused under subsection B of this section, the responsible person must remit payment of the noticed costs, expenses, and/or fees to the city of St. Helena within forty-five (45) days of the issuance of the citation. The city shall provide the responsible person notice of the right to request an administrative hearing to challenge the cost recovery, and the time for requesting that hearing. The payment of any such costs shall be stayed upon a timely request for an administrative hearing made pursuant to Section 10.36.080, and if such a request is made, shall remain stayed during the pendency of the administrative hearing process. (Ord. 17-3 § 2 (Exh. A)
10.36.080 Challenge to administrative citation.¶
In accord with the following provisions, any person dissatisfied with the city’s issuance of an administrative citation under Section 10.36.070 may request an administrative hearing to challenge the citation:
A. The responsible person shall have the right to request the administrative hearing within forty-five (45) days of the issuance of the administrative citation and imposition of the civil penalty. To request such a hearing, the responsible person shall notify the city clerk in writing within forty-five (45) days of the issuance of the citation. The appeal notification shall include all specific facts, circumstances, and arguments upon which the appeal is based.
B. The city manager is hereby authorized to designate a hearing officer to hear such appeal. The city hearing officer shall conduct a hearing on the appeal within ninety (90) days of the request for the hearing unless one of the parties requests a continuance for good cause. The hearing officer shall only consider those facts, circumstances, or arguments that the responsible person has presented in the appeal notification.
C. The hearing officer shall render a decision in writing within thirty (30) days of the conclusion of the hearing. The hearing officer shall have discretion to reduce the amount of the administrative citation based upon evidence presented by the responsible person that such a reduction is warranted by mitigating factors including, without limitation, lack of culpability and/or inability to pay. Provided, however, that in exercising its discretion the hearing officer should consider the purpose of this chapter to prevent and deter violations and whether the reduction of civil penalties will frustrate that purpose by resulting in the responsible person’s enrichment or profit as a result of the violation of this chapter.
D. Any aggrieved party to the hearing officer’s decision on the administrative appeal may obtain review of the decision by filing a petition for writ of mandate with the Napa County superior court in accordance with the timelines and provisions set forth in Government Code Section 53069.4.
E. If, following an administrative hearing, appeal, or other final determination, the responsible person is determined to be liable for the administrative citation, such liability, if unpaid within forty-five (45) days of the notice of the final determination, may be recovered by civil action. (Ord. 17-3 § 2 (Exh. A)
10.36.090 Remedies cumulative—Actions—Relationship to other laws.¶
The remedies provided under this chapter are cumulative, and shall not restrict the city to any other remedy to which it is entitled under law or equity. Nothing in this chapter shall be deemed to conflict with any penalty or provision under state law, or prohibit any conduct authorized by the state or federal constitutions. If any section, subsection, sentence, clause, phrase, or word of this chapter is for any reason held to be invalid by a court of competent jurisdiction, such decision shall not affect the validity of the remaining portions of this chapter.
