In accordance with statutes relative to adoption by reference now or hereafter in effect, the Council may enact any appropriate Colorado Statute or any standard code promulgated or enacted by any municipality, county, state or federal agency, or by recognized trade or professional organizations, by reference thereto in an enacting ordinance and without publishing such statutes or codes in full. In the event that any such statute or code, after being adopted by reference, is revised or amended by the agency or organization by whom it was enacted or promulgated, then any such revision or amended version may be adopted by reference by an ordinance passed in the usual manner without strict compliance with the statutory regulations relative to notices and public hearings.
