Louisiana Revised Statutes Tit. 2, § 345. Authority to levy special tax

A. Whenever an election is called by the board of commissioners of the airport and transportation authority to vote on the question of incurring debt and issuing bonds for the purpose of acquiring, constructing, equipping, or maintaining an airport or airport facilities, the board may submit to the qualified electors of the district in the same election, in the manner provided in Chapter 4 of Subtitle II of Title 39, a proposition to levy a special tax for the purpose of maintaining and operating the airport and airport facilities to be acquired or constructed by the authority. The special tax shall not exceed five mills on the dollar for a period not to exceed ten years.

B. The provisions of this Section shall not prohibit the voting of such maintenance tax by the authority which has acquired or proposes to acquire its airport and airport facilities through means other than the issuance of bonds, nor shall they prohibit the submission of such a proposition at a time other than that at which an election is called for the purpose of authorizing the incurring of debt and issuance of negotiable bonds therefor.
