(a) The clerk of the board shall cause a proposed ordinance or proposed amendment to an ordinance, and any ordinance adopted by the board, to be published at least once, in a newspaper of general circulation published and circulated in the board’s area of jurisdiction. (b) The publication of an ordinance, as required by subdivision (a), may be satisfied by either of the following actions: (1) The board may publish a summary of a proposed ordinance or proposed amendment to an ordinance. The summary shall be prepared by a person designated by the board. The summary shall be published and a certified copy of the full text of the proposed ordinance or proposed amendment shall be posted in the office of the clerk of the board at least five days prior to the board meeting at which the proposed ordinance or amendment is to be adopted. Within 15 days after adoption of the ordinance or amendment, the board shall publish a summary of the ordinance or amendment with the names of those board members voting for and against the ordinance or amendment and the clerk shall post in the office of the clerk a certified copy of the full text of the adopted ordinance or amendment along with the names of those board members voting for and against the ordinance or amendment. (2) If the person designated by the board determines that it is not feasible to prepare a fair and adequate summary of the proposed ordinance or amendment, and if the board so orders, a display advertisement of at least one-quarter of a page in a newspaper of general circulation in the board’s area of jurisdiction shall be published at least five days prior to the board meeting at which the proposed ordinance or amendment is to be adopted. Within 15 days after adoption of the ordinance or amendment, a display advertisement of at least one-quarter of a page shall be published. The advertisement shall indicate the general nature of, and provide information regarding, the adopted ordinance or amendment, including information sufficient to enable the public to obtain copies of the complete text of the ordinance or amendment, and the names of those board members voting for and against the ordinance or amendment.
