Section 511.   ADOPTION OF ORDINANCES AND RESOLUTIONS.
   With the sole exception of emergency ordinances which take effect upon adoption, referred to in this Article, no ordinance shall be adopted by the City Council on the day of its introduction, nor within five days thereafter nor at any time other than at a regular or adjourned regular meeting. At the time of its introduction an ordinance shall become a part of the proceedings of such meeting in the custody of the City Clerk. At the time of adoption of an ordinance or resolution it shall be read in full, unless the City Council has adopted a motion at such meeting waiving the reading in full of all ordinances or resolutions adopted at such meeting, or the reading in full of the specific ordinance or resolution is waived by a motion duly adopted by the City Council, except that emergency ordinances shall either be read in full or the full text of such emergency ordinance shall be made available to the public prior to adoption thereof. An emergency ordinance may be made available to the public for review prior to its adoption in compliance with the preceding sentence by either (i) a statement on the printed agenda of the City Council meeting at which the emergency ordinance is to be adopted indicating that a copy of the full text of the proposed ordinance is available for public review in the City Clerk's Office, or (ii) whether or not such ordinance appears on the printed agenda of the meeting at which it will be adopted, by publicly announcing at the City Council meeting at which the emergency ordinance is to be adopted that the full text of the emergency ordinance is available for public review and by posting a copy of the full text of the emergency ordinance at or near the entrance of the City Council chambers or otherwise making the full text of the emergency ordinance available to the public prior to its adoption. In the event that any ordinance is altered after its introduction, the same shall not be finally adopted except at a regular or adjourned regular meeting held not less than five days after the date upon which such ordinance was so altered. The correction of typographical or clerical errors shall not constitute the making of an alteration within the meaning of the foregoing sentence.
   No order for the payment of money shall be adopted or made at other than a regular or adjourned regular meeting.
   Unless a higher vote is required by other provisions of this Charter, the affirmative votes of at least four members of the City Council shall be required for the enactment of any ordinance or resolution, or for the making or approving of any order for the payment of money. All ordinances and resolutions shall be signed by the Mayor and attested by the City Clerk.
   Any ordinance declared by the City Council to be necessary as an emergency measure for the immediate preservation of the public peace, health, or safety, and containing a statement of the reasons for its urgency, may be introduced and adopted at one and the same meeting if passed by the affirmative votes of at least four-fifths of the total members of the City Council.
