§ 151.15  VARIANCES AND MODIFICATIONS.
   (A)   Planned unit development. The design requirements of this chapter may be modified in the case of planned unit development, upon determination by the Planning Commission that the proposed development will provide adequate public spaces and fully meet needs for light, air, service, circulation, recreation and livability. Before approval of any such planned unit development, a detailed site plan shall be submitted in accordance with the provisions of this chapter and provisions shall be made for such covenants and other legal provisions as will ensure that the plan will be carried out.
   (B)   Variances. Where, because of unusual topographical conditions peculiar to the site or because of unusual shape of the property, the Planning Commission finds that strict adherence to the requirements of this chapter would result in extraordinary hardship to the subdivider, or builder including but not limited to summer homes or vacation cottages built on mountainous or rough terrain, it may permit a variance in the regulations so that substantial justice is done and the public interest secured; provided that the granting of such variance will alleviate a clearly demonstrable hardship as distinguished from a special privilege or convenience sough by the subdivider; and, provided further that such variance will not have the effect of nullifying the intent of this subchapter.
   (C)   Conditions. In granting variance and modifications, the Planning Commission may impose such conditions as will, in its judgment, secure substantially the objectives of the standards or requirements so varied or modified.
