A. The district shall have authority to construct and/or acquire land and improvements to construct, operate, and maintain facilities, improvements, infrastructure, industrial parks and/or industrial plant buildings within the district, including sites and other necessary property or appurtenances therefor, and to acquire, construct, improve, operate, maintain and provide improvements and services necessary therefor, including but not limited to buildings, roads, street lighting, bridges, rail facilities, drainage, sewers, sewerage disposal facilities, solid waste disposal facilities, waterworks and other utilities and related properties. The district shall also have the authority to sell, lease or otherwise dispose of, by suitable and appropriate contract, to any enterprise locating or existing within the district, all or any part of an industrial plant site, industrial plant building or other property owned by the district. In determining the consideration for any contract to lease, sell or otherwise dispose of lands, buildings or other property of the district, the board may take into consideration the value of the lands, buildings or other properties involved as well as the potential value of the economic impact of the industrial or business enterprise being induced to locate or expand within the district. Such economic impact shall include increased employment, increased use of local labor, wages and salaries to be paid, consumption of local materials, products and resources and special tax revenues to be generated by the industrial or business enterprise acquiring or leasing lands, buildings or other property from the district. In no event, however, and under no circumstances shall the board dispose of any property of the district for less than fifty percent of the appraised value of the property without the prior approval of the governing authority of the parish, which approval shall be by resolution adopted by a simple majority. The resolution or ordinance adopted by the board authorizing any lease, sale or other disposition of lands, buildings or other property of the district shall set forth, in a general way, the terms of the authorized lease, sale or other disposition and such resolution or ordinance shall be published as soon as possible in one issue of the official journal of the district or board. For a period of thirty days from the date of publication of any such resolution or ordinance, any interested person may contest the legality of such resolution or ordinance or the validity of the authorized lease, sale or other disposition of district property, after which time, no one shall have any cause of action to contest the legality of said resolution or ordinance or to draw in question the legality of the authorized lease, sale or other disposition of district property for any cause whatsoever, and it shall be conclusively presumed thereafter that every legal requirement has been complied with, and no court shall have authority to inquire into such matters after the lapse of said thirty days.
