If any article, section, subsection, sentence, clause, phrase, term, provision, condition, covenant, or portion of this chapter is for any reason held to be invalid or unenforceable by any court of competent jurisdiction, or superseded by state or federal legislation, rules, regulations, or decision, the remainder of this chapter shall not be affected thereby but shall be deemed as a separate, distinct, and independent provision, and such holding shall not affect the validity of the remaining portions hereof, and each remaining section, subsection, sentence, clause, phrase, provision, condition, covenant, and portion of this chapter shall be valid and enforceable to the fullest extend permitted by law. In the event that federal or state laws, rules, or regulations preempt a provision or limit the enforceability of a provision of this chapter, then the provision shall be read to be preempted only to the extent required by law. In the even such federal or state law, rule, or regulation is subsequently repealed, rescinded, amended, or otherwise changed so that the provision hereof that had been preempted is no longer preempted, such provision shall thereupon return to full force and effect, and shall thereafter be binding, without the requirement of further action on the part of the city. (Ord. 4734 §1, 2000).
