The Board shall fix a reasonable time for the hearing of the appeal, give public notice thereof in the same manner as set forth in § 410-112 of this chapter, as well as due notice to the parties of interest, and decide the same within 30 days of the hearing. The hearing of any appeals shall be at a separate meeting from the hearing of any variance or special use permit applications, although such hearings may be held on the same day or night. At the hearing, any party may appear in person or by agent or by attorney. The officer or a designated individual of the agency, commission or board from whom the appeal is taken shall appear before the Zoning Board of Review at the hearing to represent such agency, commission or board. Other members of the agency, commission or board may appear and be heard, but shall not represent the agency, commission or board. The cost of any notice required for the hearing shall be borne by the appellant.
