La. Stat. tit. 33 § 4222
Whenever the governing authority of any municipal corporation or district desires to issue bonds to be secured as provided in R.S. 33:4221 it shall, by resolution adopted by a vote of two-thirds of its members, order an election to be held to determine whether or not it is the sense of the qualified resident electors of the municipality or district that the bonds be so issued and secured. The resolution shall set forth specifically the amount of bonds proposed to be issued, the number of years they shall run, the maximum rate of interest which they shall bear, the purpose for which they are to be issued, and a particular description of the property to be mortgaged and the income and revenues which are to be pledged for the security of the bonds, and shall designate the date of the election and the polling places. Notice of the election shall be given by publication for thirty days in a newspaper published in the municipality or district; or if there be no newspaper published in the municipality or district, then in a newspaper published in the parish. Publication for four successive weeks shall be deemed sufficient if thirty days intervene between the first publication and the date of the election.
If there be no newspaper published in the parish, then the notice may be given by posting for thirty days prior to the election in five public places within the municipality or district. The notice shall embrace substantially all matters required to be set forth in the resolution ordering the election, and shall be signed by the chief executive officer of the municipality or of the district.
