Upon the findings of the Board that, due to special conditions peculiar to a subdivision or a site, certain requirements of this Part
1 are inappropriate or that strict compliance with said requirements may cause extraordinary and unnecessary hardship, the Board may vary or waive said requirements, provided that such variance or waiver will not be detrimental to the public health, safety or general welfare or have the effect of nullifying the intent and purpose of the Official Map, Chapter
300, Zoning, the Comprehensive Plan or this Part
1. In varying or waiving certain requirements, the Board may specify such conditions as will, in its judgment, secure substantially the objectives of the requirements so varied or waived.
