La. Stat. tit. 33 § 130.17
The governing authority of a parish may abolish an industrial area or remove a portion of the territory from an industrial area only if the industry or industries located therein fail to furnish at the expense of said industry or industries any of the services listed in R.S. 51:1202 for an extended period of time and only if there is a definite need for such services in the portion of the industrial area involved. The parish governing authority may abolish an industrial area or remove a portion of the territory from an industrial area only by resolution adopted after not less than one public hearing on the question. The resolution of a parish governing authority to abolish an industrial area or remove a portion of the territory from an industrial area shall be effective thirty days after the resolution is adopted by the governing authority, provided that no resort to the courts is taken challenging such action prior to the expiration of such thirty days by a property owner within the area affected. If such action is taken by a property owner, the resolution of the parish governing authority shall be effective only when a judgment adverse to the property owner has been rendered and is final, executory, and definitive. In any suit by a property owner questioning the legality of action by the parish governing authority abolishing an industrial area or removing a portion of the territory from an industrial area, the burden of proof shall be on the parish to establish that certain of the services listed in R.S. 51:1202 have not been properly furnished by the industry or industries involved and that there is a definite need for such services in the area involved. The results of any final action taken under this Section which in any way alters the boundaries of an industrial area shall be filed with the clerk of court of the parish in accordance with the applicable provisions of R.S. 33:130.13.
