Any person receiving a cost recovery fee bill for public safety services pursuant to this Chapter may, within fifteen (15) days after the billing date, file with the City Clerk a written request appealing the imposition of such charges. Any billing sent pursuant to this Chapter shall inform the billed party of the right to appeal said billing. All appeals shall be made in writing, shall state the grounds for such appeal, shall specify the factual basis for the appeal and shall contain a signature verifying the truth of all matters asserted. Any appeal regarding such billing shall be heard by the City Manager, or by his or her designee, as the hearing officer. Notice of the hearing shall be sent by certified or registered mail to the appellant (unless such mail is refused or unclaimed, then the City shall send the mail via first class postage prepaid mail and such mailing shall be deemed actual service). Within ten (10) days after the hearing, the hearing officer shall give written notice of the decision of the hearing officer. If the appeal is denied in part or in full, all amounts due to the City shall be paid within thirty (30) days after notice of the decision of the hearing officer is sent by certified or registered mail to the appellant (unless such mail is refused or unclaimed, then the City shall send the mail via first class postage prepaid mail and such mailing shall be deemed actual service). The decision of the hearing officer may be appealed to the City Council pursuant to the procedure set forth in Section 8.25.090 of this Code. If such decision is not appealed, then the decision is final.
