In this zoning appeal out of Bucks County. the Commonwealth Court was asked whether the existence of man-made improvements that exceeded the permitted impervious coverage on a property could constitute a sufficient hardship to warrant the issuance of a variance. In concluding that such improvements could not, the court held that generally for a unique condition to warrant a variance it must relate to the physical conditions of the land itself and not to man-made improvements, such as poured asphalt and concrete.
