Louisiana Revised Statutes Tit. 38, § 115. Removal of works in front of levees

If any person shall erect any work in front of the levee, on the banks of the Mississippi, out of the limits of New Orleans, either by making a new levee, building houses, sheds, dikes, or keys, so as to impede its navigation, or to encroach on that part of the bank reserved by law for the use of the public, or for roads used for tracking, whether the works or buildings are only commenced or completed, without having applied to the police jury and obtained from them permission, the works shall be destroyed, or removed, if susceptible of removal, to such a distance from the river, as may be required by the ordinance of the police jury; in either case, at the expense of the owner.
