Before the City Council acts on a variance application, the applicant must prove physical hardship, and the Council must find that:
(A) There are special circumstances or conditions applying to the land, buildings, topography, vegetation, sign structures or other matters on adjacent lots or within the adjacent right-of-way, which would substantially restrict the effectiveness of the sign in question; provided, however, that such special circumstances or conditions are unique to the particular business or enterprise to which the applicant desires to draw attention, and do not apply generally to all businesses or enterprises;
(B) That such special circumstances were not created by the applicant or anyone in privy to the applicant;
(C) That the granting of the variance will be in general harmony with the purposes of this chapter, and will not be materially detrimental to the persons residing or working in the vicinity, to adjacent property, to the neighborhood, or to the public welfare in general;
(D) The variance applied for does not depart from the provisions of this chapter any more than is required to identify the applicant's business or use;
(E) Such other factors and criteria as the Council deems applicable to the proposed variance.
