12-123: POWERS RELATIVE TO VARIATIONS:
   A.   The board of adjustment shall have the power to authorize variances from the strict application of the provisions of this chapter, as well as such other ordinances as the council shall so determine, where the strict application of such provisions would result in an unnecessary hardship, and may establish such requirements relative to such property as would carry out the purpose and intent of the regulations.
   B.   The board may grant a variance only upon finding that:
      1.   The strict application of the ordinance to the particular piece of property would result in an unnecessary hardship; by reason of:
         a.   Exceptional narrowness, shallowness, or shape of a specific parcel of property at the time of the original adoption of the regulations;
         b.   Exceptional topographic conditions; or
         c.   Other extraordinary or exceptional situation or condition of a specific parcel of property;
      2.   The conditions are peculiar to the particular piece of property involved; and
      3.   Relief, if granted, would not cause substantial detriment to the public good, or impair the purposes and intent of the ordinance or the comprehensive plan. (Prior code § 16-48)
