Waivers. The provisions of this article are intended as a minimum standard for the protection of public health, safety, and welfare. Any person desiring a waiver of the requirements of this article shall make application for such waiver in writing, identifying the section of the article from which a waiver is requested, the reasons for the waiver, and the alternative proposed. If the literal compliance with any mandatory provision of this article is shown by the applicant, to the satisfaction of the Board of Supervisors, to be unreasonable or to cause undue hardship as it applies to a particular property, or if the applicant evidences that an alternative proposal will allow for equal or better results, the Board of Supervisors may grant a waiver from such mandatory provisions so as to permit the reasonable utilization of the property. The granting of any such waiver shall not have the effect of making null and void the intent and purpose of this article. In granting a waiver, the Board of Supervisors may impose such conditions as will, in its judgment, secure substantially the objectives of the standards and requirements of this article.
