Neb. Rev. Stat. §§ 15-724
The mayor and city council of a city of the primary class may by ordinance purchase and own grounds for and erect and establish market houses and market places, regulate and govern such market houses and market places, and prescribe the fees to be charged persons for stalls therein. Any revenue from such fees shall be applied (1) to the payment of the salaries of the officers appointed to take charge of such market house or market place, (2) to the payment of repairs of the market house or market place, and (3) to the payment of the cost of erecting such market house or market place. After all salaries, repairs, and costs of construction have been paid, the surplus, if any remaining, shall be disposed of as the city council shall direct. The mayor and city council may contract with any person or persons, or association of persons, companies, or corporations, for the erection and regulation of such market house or market place on such terms and conditions and in such manner as the city council may prescribe, and raise all necessary revenue therefor as provided in this section. The mayor and city council may locate market houses or market places on any street, alley, or public ground, or any land purchased for such purpose, and provide for the erection of all other useful and necessary buildings for the use of the city and for the protection and safety of all property owned by the city, except that any such improvement, costing in the aggregate a sum greater than five hundred dollars, shall not be authorized until the ordinance providing for such improvement shall be first submitted to and ratified by a majority of the legal voters of such city.
