This is what the State Statute says regarding first and second readings:
******************************
(2) Each ordinance or resolution shall be introduced in writing and shall embrace but one subject and matters properly connected therewith. The subject shall be clearly stated in the title. No ordinance shall be revised or amended by reference to its title only. Ordinances to revise or amend shall set out in full the revised or amended act or section or subsection or paragraph of a section or subsection.
(3)(a) Except as provided in paragraph (c) [Zoning Ordinances], a proposed ordinance may be read by title, or in full, on at least 2 separate days and shall, at least 10 days prior to adoption, be noticed once in a newspaper of general circulation in the municipality. The notice of proposed enactment shall state the date, time, and place of the meeting; the title or titles of proposed ordinances; and the place or places within the municipality where such proposed ordinances may be inspected by the public. The notice shall also advise that interested parties may appear at the meeting and be heard with respect to the proposed ordinance.
