Appeals may be taken to and before the Zoning Board of Adjustment by any person aggrieved or by any officer, department, board or bureau in the city. Such appeal shall be made by filing in the office of the City Secretary a written notice of appeal and specifying the grounds thereof. The office or department from which the appeal is taken shall forthwith transmit to the Board all of the papers constituting the record from which the action appealed was taken.
 

An appeal shall stay all proceedings in furtherance of the action appealed from unless the Building Inspector shall certify to the Zoning Board of Adjustment that, by reason of facts in the certificate, a stay would cause imminent peril to life or property, in which case proceedings shall not be stayed otherwise than by a restraining order which may be granted or [sic] by a court of equity, after notice to the office [officer] from whom the appeal was taken.
 

The Board shall fix a reasonable time for the hearing of the appeal or other matter referred to it, and shall mail notices of such hearing to the petitioner and to the owners of property lying within two hundred (200) feet of any point of the lot or portion thereof on which a variation is desired, and to all other persons deemed by the Board to be affected thereby, such owners and persons being determined according to the current tax rolls of the City. Depositing of such written notice in the mail shall be deemed sufficient compliance therewith.
 

The Board shall decide the appeal within a reasonable time. Upon the hearing, any party may appear in person or by agent or attorney. The Board may reverse or affirm wholly or partly or may modify the order, requirements, decision, or determination as in its opinion ought to be made in the premises, and to that end, shall have all powers of the officer or department from whom the appeal is taken.
