Louisiana Revised Statutes Tit. 33, § 172.1. Petition to annex territory in Jefferson Parish;  valuation of property;  notice of filing petition;  hearing concerning proposed ordinance

A. No ordinance enlarging the boundaries of a municipality in Jefferson Parish shall be valid unless prior to the adoption thereof a petition has been presented to the governing body of the municipality containing the written assent of a majority of the registered voters and a majority in number of the resident property owners as well as twenty-five percent in value of the property within the area proposed to be included in the corporate limits, provided that if the area proposed to be included in the corporate limits receives such services as water, sewerage, road lighting, garbage disposal, etc., from Jefferson Parish, then the petition presented to the governing body shall contain the written assent of a majority of the registered voters and more than fifty percent in number of the resident property owners as well as fifty percent in value of the property within the area proposed to be included in the corporate limits according to the certificate of the parish assessor.  The valuation shall be certified to by the assessor according to the assessment of each of the owners signing the petition.  Where there has been a change of ownership since the last assessment of the property, the assessor shall certify the valuation of the present owner in accordance with the last assessment appearing on the rolls against any previous owner.  In any case where the property of the present owner has not specifically been assessed, the assessor shall estimate the assessed value of the property for the current year and certify the same as the value of the property.

B. Notwithstanding any other provision of law to the contrary, no ordinance enlarging the boundaries of a municipality in Jefferson Parish shall be valid unless the area proposed to be annexed is contiguous and adjacent to the territorial corporate limits of the municipality.

C. The petition required by Subsection A shall be in writing, but no special form shall be necessary;  however, the petition shall provide a description of the general area to be annexed which shall be attached thereto.  Multiple petitions may be used to annex different properties so long as the petitions, when considered together, are capable of covering an area which has a contiguous outer boundary in which the above majority and percentage requirements for annexation are met.

D. Notice by publication shall be given once of the filing of the petition in some newspaper published or having general circulation in the municipality.  No ordinance enlarging the boundaries of the municipality shall be adopted until ten days after the publication of the notice.  Anyone desiring to be heard with reference to the proposed ordinance shall notify the clerk or secretary of the municipality in writing, and the governing authorities before adopting any ordinance shall grant such hearing.

E. Notwithstanding any other provisions of law to the contrary and except as otherwise provided in Subsection F, any area in Jefferson Parish proposed to be annexed within the corporate limits of a municipality shall consist of one or more entire voting precincts which are contiguous and adjacent to the municipality, and prior to any municipality enlarging its boundaries, the question of the annexation shall be submitted to the registered voters residing in the voting precinct or precincts of the area proposed to be annexed, in a special election called for that purpose by the municipality and held according to the provisions of R.S. 33:154 through 161.  For the annexation to take effect a majority of the registered voters residing in the voting precinct or precincts to be annexed shall have voted in favor of the annexation.

F. If an area in Jefferson Parish sought to be included within a municipal annexation either has no registered voters or consists of one or more parcels of property which do not comprise an entire voting precinct, the question of the annexation shall be submitted to the governing authority of the parish of Jefferson prior to any municipality enlarging its boundaries and, where applicable, the question of the annexation also shall be submitted to the qualified voters residing within the area proposed to be annexed in a special election called for that purpose by the municipality and held according to the provisions of R.S. 33:154 through 161.  For the annexation to take effect, the parish governing authority shall have adopted an ordinance concurring in the proposed annexation and, where applicable, a majority of qualified voters, residing within the area proposed to be annexed, voting on the proposition at such election, shall have voted in favor of the annexation.

G. The parish of Jefferson may file suit in the Twenty-Fourth Judicial District Court to contest any proposed extension of a municipality's corporate limits in Jefferson Parish that does not comply with the provisions of this Section.
