La. Stat. tit. 33 § 3883
The police jury shall hear all objections at the time appointed, or at any time to which the hearing may be adjourned and pass upon the same, and its decision shall be final and conclusive.
At the hearing the police jury may change the boundaries of the proposed district by excluding therefrom the lands of the persons objecting or by including therein the lands of persons petitioning to be included therein. After disposing of all objections, the police jury shall, if it determines to create the district, adopt an ordinance finally fixing the general boundaries of the district and giving the district a numerical designation and name as follows:
"Sewerage District No. _____ (here insert number) of the Parish of __________ (here insert name of parish)".
Notice of the formation of the district shall forthwith be given publication in a newspaper published in the parish, or if there be none, then by posting in two public places in the parish, and publication in a newspaper published in an adjoining parish. One publication shall be sufficient, but if the police jury at the time it determines to create the district, also decides to submit to the qualified property taxpaying voters the question of incurring debt and issuing bonds on the district, notice of the election may contain notice of the formation of the district and a description of the boundaries thereof. The notice of election shall be published in the manner prescribed by the general laws in relation to incurring debt and issuing bonds.
