The City Council hereby declares that it would have passed the ordinance codified in this title and each section, subsection, paragraph, sentence, clause and phrase thereof, irrespective of the fact that one or more such sections, subsections, paragraphs, sentences, clauses or phrases might be declared invalid, unconstitutional or void. Should any section, subsection, paragraph, sentence, clause or phrase of the ordinance codified in this title be declared invalid, such declaration shall not affect the validity of any other section, subsection, paragraph, sentence, clause or phrase; and if this title or any portion thereof should be held to be invalid on one ground but valid on another, it shall be construed that the valid ground is the one upon which the ordinance codified in this title or such portion thereof was enacted.
