As soon as said plans have been developed as hereinbefore provided, a report thereof shall be made by the commissioners, who shall file the same with the clerk of the chancery court. Such report shall include the approval thereof by the board of any levee district within which any master water management district shall be located in whole or in part. Such report shall contain an estimate of the local share of the cost of carrying out the works of improvement, together with an estimate of the total benefits that will accrue to the land in the proposed district. Upon the filing of said report and after fixing a time, date, and place of hearing by the chancellor, the clerk of the chancery court shall thereupon give notice by publication that a hearing will be held on said report and designating a date not less than twenty days and not more than thirty days after the last publication of notice on which such hearing will be held. Said notice shall be published in a newspaper in each county wherein a part of such district is situated, such newspaper to have a general circulation in the area in said county wherein such portion of such district may be located; and said notice shall be published for three weeks in such newspaper. If there be no newspaper published in such county, then the notice provided herein shall be posted for not less than fifteen days, with one copy being posted on the bulletin board at the county courthouse and two copies posted at public places in the area proposed to be included in the master water management district. The notice shall call upon landowners in the district to show cause, if any, against approval of the report by the chancery court.
