1. Where the Planning Commission finds that extraordinary hardships or practical difficulties may result from strict compliance with these regulations, and/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. The Planning Commission shall not approve variances unless it shall make findings based upon the evidence presented to it in each specific case that:
a. The granting of the variance will not be detrimental to the public peace, safety, health or welfare, or injurious to other property in the area where the variance is located;
b. 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 any other property;
c. 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 were to be carried out; and
d. The variances will not in any manner conflict with, or vary from, the provisions of the adopted zoning ordinance or present or future comprehensive plan.
2. 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.
