If a hearing is requested within the ten-day period as provided in § 8-308, such request shall be made in writing to the governing body. Failure to make a timely request for a hearing shall constitute a waiver of the person’s right to contest the findings of the public officer. The hearing shall be held by the governing body or its designated representative as soon as possible after the filing of the request therefor, and the person shall be advised by the city of the time and place of the hearing at least five days in advance thereof. At any such hearing, the person may be represented by counsel, and the person and the city may introduce such witnesses and evidence as is deemed necessary and proper by the governing body or its designated representative. The hearing need not be conducted according to the formal rules of evidence. Upon conclusion of the hearing, the findings of the governing body or its designated representative shall be prepared in resolution form, adopted by the governing body, and the resolution shall be served upon the person in the matter provided in § 8-310.
