La. Navigation and Shipping § 34:1655
The Greater Lafourche Port Commission may acquire by expropriation, in accordance with the expropriation laws of the state, any properties necessary for the construction of port facilities and a deep sea channel, provided, however, that said Port Commission shall not have the right to expropriate minerals or mineral rights, and shall not have the right to expropriate existing facilities. Should the properties expropriated hereunder cease to be used for the purposes for which they were expropriated, such properties shall revert to the original landowner, or his heirs or assigns, provided such landowner, or his heirs or assigns, shall reimburse said Port Commission, or its successor, in the full amount originally paid by the Port Commission for such land.
