The Administrative Board shall have the following powers and duties:
   (a)   To hear and decide appeals where it is alleged there is error in any order, requirement, decision, or determination made by the City Engineer in the enforcement of this Zoning Code.
   (b)   To interpret the provisions of this Zoning Code in such a way as to carry out the intent and purpose of the plan, as shown upon the map fixing the several districts accompanying and made a part of this Zoning Code, where the street layout actually on the ground varies from the street layout as shown on the map.
   (c)   To determine whether an industry should be permitted within the M Industrial Districts because of the methods by which it would be operated and the minimizing of dust, odor, gas, smoke or noise.
   (d)   To authorize, upon appeal, whenever a property owner can clearly show that, due to peculiar, unusual conditions applicable to his property and not to surrounding property generally the strict application of the terms of this Zoning Code results in unusual practical difficulties and particular hardship, such variation in the terms of this chapter as are in harmony with its general purpose and intent, but only when the Board is satisfied that the variation is necessary to alleviate the unusual hardship and does not merely serve as a convenience to the applicant.
   (e)   To permit, upon appeal, the following exceptions:
      (1)   The extension of a district where the boundary line of a district divides a lot in single ownership at the time of the adoption of this Zoning Code.
      (2)   The reconstruction of a nonconforming building which has been destroyed or partially destroyed, by fire or act of God, by more than seventy-five percent (75%) where the Board shall find some compelling public necessity requiring a continuance of the nonconforming use.
      (3)   The erection and use of a building or the use of premises in any location for a public service corporation for public utility purposes which the Board deems reasonably necessary for the public convenience or welfare.
      (4)   Variation of the parking and loading requirements of this Zoning Code whenever it is clearly demonstrated that the provision of the full parking or loading facilities is unnecessary in any district or where such a requirement would impose an unreasonable hardship upon the use of the lots, as contrasted with merely granting an advantage or a convenience.
      (5)   A temporary building used in conjunction with construction work, but only for the period, not exceeding one year unless the permit is renewed, during which the construction is in progress, provided that any such temporary building shall be removed on completion of the construction work.
