B. Authorize, upon appeal, in specific cases, such variance from the terms of this zoning resolution as will not be contrary to the public interest, where, owing to special conditions, a literal enforcement of this resolution will result in unnecessary hardship, and so that the spirit of this resolution shall be observed and substantial justice done.

At the hearing, the holder may appear in person, by his attorney or other representative, or he may present his position in writing.
