A. Where the planning commission finds that extraordinary hardships or practical difficulties may result from strict compliance with these regulations or the purposes of these regulations may be served to a greater extent by an alternative proposal, it may approve variances to these subdivision regulations so that substantial justice may be done and the public interest secured; provided that such variance shall not have the effect of nullifying the intent and purpose of these regulations; and further provided the planning commission shall not approve variances unless it shall make findings based upon the evidence presented to it in each specific case that:
1. The granting of the variance will not be detrimental to the public safety, health, or welfare or injurious to where other property is located;
2. The conditions upon which the request for a variance is based are unique to the property for which the variance is sought and are not applicable generally to other property;
3. Because of the particular physical surroundings, shape or topographical conditions of the specific property involved, a particular hardship to the owner would result, as distinguished from a mere inconvenience, if the strict letter of these regulations is carried out; and
4. The variance will not in any manner vary the provisions of the zoning ordinance, master plan or official map.
B. In approving variances, the planning commission may require such conditions as will, in its judgment, secure substantially the objectives of the standards or requirements of these regulations.
C. A petition for any such variance shall be submitted in writing by the subdivider at the time when the preliminary plat is filed for the consideration of the planning commission. The petition shall state fully the grounds for the application and all of the facts relied upon by the petitioner. (Res. 901, 5-10-1977)
