Where the Planning Board finds that because
of unusual circumstances of shape, topography or other physical features
of the proposed subdivision or because of the nature of adjacent developments
extraordinary hardship may result from strict compliance with these
regulations, it may change the regulations according to § 7-728
of the Village Law and as authorized by the Village Board of Trustees
so that substantial justice may be done and the public interest secured;
provided, however, that no such change shall be granted which will
have the effect of nullifying the intent and purpose of the Official
Map (as it may be adopted), the Zoning Ordinance, these regulations or any other pertinent rules, regulations
or laws of the Village. In granting changes and modifications, the
Planning Board may require such conditions as will, in its judgment,
secure substantially the objectives of the standards or requirements
so changed or modified.
