La. Navigation and Shipping § 34:329
The board may charge a reasonable fee to each vessel arriving in ballast or carrying cargo of any kind. It may also charge for each copy of any certificate issued by it or its deputies for inspecting hatches, surveying cargoes and the like. The master of each vessel shall, however, be furnished free one copy of all surveys upon his vessel or cargo.
The board may, when necessary, levy annually an ad valorem tax not to exceed two and one-half mills on the dollar on the property subject to taxation situated in the district. All funds derived under this section may be used to defray the administrative, operative and maintenance expenses of the board and/or to pay principal, interest and redemption costs on bonds of said district as hereinafter provided.
The board may likewise borrow money from time to time for the purpose of defraying the administrative, operative and maintenance expenses of the board and may issue certificates of indebtedness secured by any fees authorized under this Part and by any taxes authorized under this section, provided that any loan for this purpose shall in no year exceed the estimated revenues for such year.
With the approval of the State Bond and Tax Board, said district, through the board as its governing authority, is authorized to incur debt for its lawful purposes and to issue negotiable bonds in its name representing the debt, and to pledge and dedicate for the payment of the principal and interest of such negotiable bonds the revenue derived from the ad valorem tax authorized by this section and/or other revenues received by the district or the board from other sources, as may be provided by the board in the resolution authorizing the issuance of such bonds and providing the security therefor; provided, however, that such bonds shall not be issued requiring principal and interest payments in any year in excess of eighty per cent of the tax revenues which would have been received by the district had the two and one-half mill tax been levied on the last assessment roll filed and of record. Such bonds shall be issued by the board with such dates, forms, terms, series, interest rates, maturities, denominations, redemption provisions and security provisions as the board may determine in compliance with this Section and the provisions of Article XIV, Section 31 of the Constitution of the State of Louisiana for the year 1921, as amended. Such bonds, when authorized to be issued, shall constitute a general obligation of the district to the payment of which the full faith and credit of the district shall be and is hereby pledged. In addition to the pledge of said tax and/or other revenues to secure the payment of said bonds in principal and interest, the board may further secure their payment by a conventional mortgage upon any and all of the properties constructed or acquired, or to be constructed and acquired by it from the proceeds of such bonds. In the event any bonds are issued secured by a pledge and dedication of said tax revenues, said tax shall be levied and collected as long as said bonds are outstanding in an amount sufficient to pay such bonds in principal and interest as they respectively mature. Any resolution authorizing the issuance of bonds of the district may contain such covenants as the board may deem proper to assure the enforcement, collection and proper application of tax or other revenues pledged and dedicated to the payment and security of the bonds, and other security provisions including the establishment of a bond reserve if deemed advisable by the board.
Except as specifically provided in this section, said bonds shall be issued in compliance with the requirements of R.S. 34:330 and said Article XIV, Section 31 of the Constitution, including the public sale of such bonds and the thirty day prescriptive period to contest the legality of such bonds and the security therefor, all as more fully therein provided.
