No ordinance shall contain more than one subject which shall be fully and clearly expressed in its title. Ordinances shall be presented to each member of the city council and the mayor in written form prior to any vote thereon; provided, that revisions and amendments may be made by voice vote at the meeting. Ordinances which meet these requirements may be passed without having the ordinance read in full at the meeting but shall require only that the title to the ordinance be read aloud at the meeting and that thereafter the procedures in voting referred to in RCW 35A.12.130, 35A.12.150 and 35A.12.160 be complied with. (Ord. 620 § 1, 1971)
