Council shall have the authority to permit a variation in the sign requirements in any zoning district where there are unusual and practical difficulties or unnecessary hardships in complying with such requirements, provided that any such variation shall not unreasonably affect any adjoining property or the general welfare and further provided that the purpose and intent of the sign requirements not be diminished any more than is reasonably necessary to permit the variation.
