Idaho Code § 50-326
Whenever any city in this state shall own its own water plant, water system, electric power plant or electric light and power transmission and electric distribution system or natural gas distribution system, the city council of such city may lease and sell such systems, provided, however, that before doing so, the question of leasing or selling such property shall be submitted to the qualified electors who pay taxes on real property within said city, at a special election held for that purpose, and if a majority of the votes cast at such election are in favor of leasing or selling such property, the city council may then lease or sell the same; but in case the majority of the votes cast at such special election shall be against the leasing or selling of such property, the city council shall have no power to lease or sell the same. The election to be called shall be held only after notice thereof has been published at least once a week for two (2) consecutive weeks, before the election, in the official newspaper of said city. Notice of such special election shall also be posted by the city clerk in three (3) public places in such city, at least ten (10) days before such special election. A city council may enter into agreements pursuant to this section to lease with the option to sell any plant or system described in this section. A city council may only terminate such lease/option to sell agreements during the term of the agreement for default by the entity leasing such plant or system. Such lease/option to sell agreements are subject to the voter approval requirements of this section.
