If any article, section, subsection, provision, regulation, limitation, restriction, sentence, clause, phrase, or word in the Zoning Ordinance or the zoning district boundaries as shown on the zoning map shall, for any reason, be declared to be illegal, unconstitutional, or invalid by any court of competent jurisdiction, such decision shall not affect or impair the validity of the Zoning Ordinance as a whole or any of the remaining articles, sections, subsections, provisions, regulations, limitations, restrictions, sentences, clauses, phrases, words, or remaining portions of the Zoning Ordinance. The remaining portions of the ordinance shall remain in effect as though the part or section declared unconstitutional or invalid was never a part thereof.
