A.
In any case in which an applicant demonstrates to the satisfaction of the Council that strict application of any provisions of this chapter would be unreasonable and would cause unnecessary hardship as applied to the proposed subdivision or land development, the Council may grant a modification of such provision so as to grant relief from the unnecessary hardship. Any such modification granted shall be the least modification necessary to grant relief from the unnecessary hardship and shall be applied so that substantial justice may be done and the public interest secured; provided, however, that such modification shall not be granted if it would have the effect of nullifying the intent and purpose of this chapter.
B.
In granting modifications, the Council may impose such conditions as will, in its judgment, secure substantially the objectives of the standards and requirements so modified.
