Each chapter, section, paragraph, sentence, clause, phrase, or other divisible part of the Subdivision Regulations is hereby declared to be severable and if any such chapter, section, paragraph, sentence, clause, phrase, or other divisible part is declared unconstitutional or otherwise invalid by any court of competent jurisdiction in a valid judgment or decree, such unconstitutionality or invalidity shall not affect any of the remaining chapters, sections, paragraphs, sentences, clauses, phrases, or other devisable part of these Regulations since the same would have been enacted without the incorporation into these Regulations of such unconstitutional or invalid chapter, section, paragraph, sentence, clause, phrase, or other devisable part.
