Iowa Code § 380.3: Two considerations before final passage — how waived.

A proposed ordinance or amendment must be considered and voted on for passage at two council meetings prior to the meeting at which it is to be finally passed, unless this requirement is suspended by a recorded vote of not less than three-fourths of all of the members of the council. If a proposed ordinance, amendment, or resolution fails to receive sufficient votes for passage at any consideration and vote thereon, the proposed ordinance, amendment, or resolution shall be considered defeated.
