Variances from the standards of this title may be authorized by the city council in accordance with the procedures set forth in title 13 of this code, zoning. In granting such a variance, the city council, after review and recommendation by the planning commission, shall find:
A. Because of the special circumstances applicable to the subject property, including size, shape, topography, location or surroundings, or the size or nature of the critical area, the strict application of this title would deprive the property owner of reasonable use of their property;
B. The granting of the variance is the minimum necessary to accommodate the development proposal and will not be materially detrimental to the public welfare or injurious to the property or improvements in the vicinity and zone in which the property is situated, or contrary to the goals and purposes of this title.
