§ 9.10.100. Administrative monetary penalties.¶
As an alternative to punishment as an infraction, the sheriff may assess an administrative monetary penalty pursuant to California Government Code Section 53069.4. Administrative penalties shall be assessed in accordance with the procedures set forth in this section. Unless otherwise stated, administrative monetary penalties shall be the maximum amounts specified in Government Code Section 25132.
A. Notice of Violation. When a violation of any of the provisions of this article is identified, the sheriff shall issue a notice of violation to the responsible person(s). The notice shall contain the following information: (1) date, approximate time, and address or definite description of the location where the violation(s) occurred; (2) the code section violated and a description of the violation; (3) the amount of the monetary penalty for the violation(s); (4) an explanation of how the penalty shall be paid, the time period by which it shall be paid, and the place to which the penalty shall be paid; (5) identification of rights of appeal, including the time within which the notice may be contested and the place to obtain a notice of appeal and request for hearing form to contest the notice of violation; and (6) the name and signature of the citing officer and, if possible, the signature of the responsible person(s). A single notice of violation may charge a violation for the violation of one or more code sections.
B. Service of Notice of Violation. The sheriff shall impart notice to the responsible person(s) of the violation in the following manner:
Personal Service. The sheriff shall attempt to locate and personally serve the responsible person(s) and, if possible, obtain the signature of the responsible person(s) on the notice of violation. If the responsible person served refuses or fails to sign the notice, the failure or refusal to sign shall not affect the validity of the notice or of subsequent proceedings.
Mail. If, for any reason, the sheriff is unable to personally serve the notice of violation on the responsible person(s), the notice shall be mailed to the responsible person(s) by certified mail, postage prepaid with a requested return receipt. Concurrently, the citation shall be sent by regular mail. Service by mail shall be sent to the responsible person's address as shown on public records or as known by the county. If the notice is sent by certified mail and returned unsigned, then service shall be deemed effective by regular mail, provided the notice sent by regular mail is not returned by the post office. Service by mail shall be effective on the date of mailing.
The failure of any responsible person(s) to receive any notice served in accordance with this section will not affect the validity of any proceedings taken under this chapter.
C.
- Satisfaction of Notice of Violation.
- Upon receipt of a notice of violation, the responsible person(s) must pay the administrative penalty to the county.
- If a responsible person fails to pay the administrative penalty, the responsible person(s) shall pay the accrued penalty amount to the county.
D. Appeal.
Any recipient of a notice of violation may contest that there was a violation of this article, or that he or she is the responsible person(s) by completing a notice of appeal and request for hearing form and filing it with the sheriff within 15 calendar days from the date of issuance of the notice, together with an advance deposit of the total amount of the monetary penalty. Any appeal of the notice of violation must include a detailed written explanation of the grounds for appeal.
Any penalty amount that has been deposited in advance shall be refunded if it is determined, after a hearing, that the person charged in the notice of violation was not responsible for the violation(s) or that there was no violation(s) as charged in the notice of violation.
The failure to submit a timely and complete request for hearing will terminate a person's right to contest the notice of violation and result in a failure to exhaust administrative remedies, and the order of the notice of violation will serve as a formal determination and conclusive evidence of the named responsible person(s)'s liability.
E. Hearing Officer. A county hearing officer, selected by the sheriff shall conduct the administrative hearing.
F. Hearing Procedure. The following rules shall apply to the conduct of a hearing under this section:
No hearing to contest an administrative penalty before a hearing officer shall be held unless and until a notice of appeal and request for hearing form has been completed and timely filed, and the total amount of the penalty has been timely deposited in advance with the sheriff.
The hearing before the hearing officer shall be set for a date that is not less than 15 and not more than 60 calendar days from the date that the notice of appeal is filed in accordance with the provisions of this section. The person requesting the appeal shall be notified of the time and place set for the hearing at least 10 calendar days prior to the date of the hearing.
The hearing officer shall only consider evidence relevant to whether the violation(s) occurred and whether the person filing the appeal is the responsible person.
The person contesting the administrative penalty shall be given the opportunity to testify and present witnesses and evidence concerning the alleged violation.
The failure of any recipient of a notice of violation to appear at the hearing or, in the alternative, to present written or demonstrative evidence shall constitute an admission of the violation by the recipient and an admission that the amount of the administrative penalty is appropriate as well as a failure to exhaust administrative remedies that may bar judicial review.
The notice of violation and any additional documents submitted by the sheriff shall constitute prima facie evidence of the respective facts contained in those documents.
If the sheriff submits an additional written report concerning the alleged violation to the hearing officer for consideration at the hearing, then a copy of this report also shall be served by first class mail on the person requesting the hearing at least five days prior to the date of the hearing.
At least 10 days prior to the date of the hearing, the recipient of a notice of violation shall be provided with copies of the notices, reports and other documents submitted or relied upon by the sheriff. No other discovery is permitted. Formal rules of evidence shall not apply.
The hearing officer may continue the hearing and request additional information from the sheriff or the recipient of the notice of violation prior to issuing a written decision.
The hearing officer is not required to provide transcripts of hearings, but is required to make available tapes of hearings for a fee.
G. Hearing Officer's Decision.
After considering all of the testimony and evidence submitted at the hearing, the hearing officer shall issue a written decision within 10 days of the date of the hearing to uphold or cancel the notice of violation and shall list in the decision the reasons for that decision. The decision of the hearing officer shall be final.
If the hearing officer determines that the notice of violation should be upheld, then the sheriff shall retain the penalty amount, including any fee that is the subject of the notice of violation, on deposit with the sheriff.
If the hearing officer determines there has been no violation and the penalty was deposited with the sheriff, then the county shall promptly refund the amount of the deposited penalty.
The recipient of the notice of violation shall be served with a copy of the hearing officer's written decision.
H. Right to Judicial Review. Any person aggrieved by the administrative decision of the hearing officer may obtain review of the administrative decision by filing a petition for review with the Placer County Superior Court in accordance with the timelines and provisions as set forth in California Government Code Section 53069.4.
(Ord. 5907-B § 1, 2018)
§ 9.10.110. Failure to pay response costs and/or administrative penalties.¶
A. The failure of any person to timely pay either the response costs or the assessed administrative penalties constitutes a debt to the county and may result in the matter being referred to the Placer County department of administrative services, which may file a claim with the small claims court or, in the alternative, utilize any means within its power to collect the amount owed. The county may pursue any other legal remedy to collect the administrative fines.
B. Any person who fails to pay to the county any response costs or administrative penalty imposed pursuant to this article on or before the date such costs or penalty are due shall also be liable in any action brought by the county for all costs incurred in securing payment of the delinquent amount, including, but not limited to, administrative costs and attorneys' fees. Such collection costs are in addition to any required fees, penalties, interest and late charges.
C. Notwithstanding all of the procedures set forth in this section, the sheriff shall have the ability and discretion to enforce violations of this article, to impose necessary conditions, to forgive portions of a debt or penalty owed to the county under this article, and to coordinate collection and enforcement efforts.
(Ord. 5907-B § 1, 2018)
§ 9.10.120. No duty to enforce.¶
Nothing in this article shall be construed as imposing on the sheriff or the county of Placer any duty to issue any violations of this article and neither the sheriff, district attorney, nor the county, shall be held liable for failure to issue a citation for violation of this article. (Ord. 5907-B § 1, 2018)
§ 9.10.130. Severability.¶
The provisions of this article are declared to be separate and severable. The invalidity of any clause, phrase, sentence, paragraph, subdivision, section or portion of this article, or the invalidity of the application thereof to any person or circumstance shall not affect the validity of the remainder of this article, or the validity of its application to other persons or circumstances. (Ord. 5907-B § 1, 2018)
