The council may provide for the revision and codification of its ordinances, bylaws and permanent resolutions, or for the adoption of a code or codes by ordinance. Such code or codes and the revisions or amendments thereof may relate to the whole system of city bylaws, ordinances and permanent resolutions, or may relate to that portion of such ordinances, bylaws and permanent resolutions which relate to, affect or purport to govern any particular subject of municipal legislation. The council shall have full power and authority to prescribe the manner in which said code or codes, revisions or amendments thereto, shall be made public, whether by proclamation of any officer of said city by posting or by publication, one or all, but it shall not be necessary unless so prescribed by the council for such code or codes, revisions or amendments thereto, to be published in a newspaper or newspapers unless such codes, revisions, or amendments include theretofore unpublished substantial changes, in which case such changes along with at least so much of the context thereof as is necessary to convey the meaning of such changes shall be published in accordance with then existing state law. Nor shall it be necessary that such code or codes, revisions or amendments thereto, be spread at length upon the minutes, but they will be noted in the minutes. The council may prescribe that such code or codes, revisions or amendments thereto may be certified by and filed with the city clerk, or other corresponding officer, in lieu of spreading at length the same on the minutes; and the council may prescribe the manner in which copies of such code or codes, revisions or amendments thereto, may be officially certified for use by the residents or by the courts. The council may adopt and provide for the maintenance in a designated office of the city of a comprehensive zone map of the city open for inspection by the public at all reasonable times, and may make such zone map a part of any ordinance by reference thereto in such ordinance and without publication of such zone map in any newspaper. Such zone map need not be in one piece but may for convenience be in sections. A zone map of territory newly added to the city shall be treated as a comprehensive zone map of the city for purposes of application of the provisions of the preceding sentence. These provisions are subject to the publication and recordation of ordinances as set out in section 11-45-8.
