That such variance, if granted, will not constitute a special privilege, inconsistent with the limitations imposed upon other property in the vicinity and similarly zoned; and
That the granting of the variance will not be materially detrimental to the public welfare or injurious to the adjacent property; and
That the granting of the variance will be consistent with the purpose and intent of the provisions of this title.
