When any levee board or levee and drainage board desires to sell or lease any lands which it owns, the board shall comply with the advertising and bid requirements contained in R.S. 41:131 et seq., R.S. 41:1212 et seq., or R.S. 41:1261 et seq., provided the aforesaid Sections do not preclude compliance with any federal contract or grant agreement or any federal laws, rules, or regulations within the area of any airport. However, any levee board or levee and drainage board may execute a campsite lease of not over three years on lands owned, or which may hereafter be acquired, for a cash consideration and under the terms and conditions which the board of commissioners of the levee districts or levee and drainage districts may deem best. All such leases shall be subordinate to any lease hereafter made of the lands for oil, gas, and mineral development. A further exception to the provisions of this Section and R.S. 38:302 shall be for those leases for hunting, trapping, and fishing leases not exceeding ten years and except when leasing those lands located within, in, or when it is a part of a marina used for boat mooring facilities when the terms do not exceed fifty-five years or when leasing airport facilities to a fixed base operator, bulk fuel facilities, and airport hangars when the term does not exceed fifty-five years.
