Idaho Code § 31-4510
Neither this chapter nor anything herein contained shall be construed as a restriction or limitation upon any powers which any county might otherwise have under any laws of this state, but shall be construed as cumulative of any such powers. No proceedings, notice or approval shall be required for the issuance of any revenue bonds or any instrument as security therefor, except that no revenue bonds shall be issued hereunder until the board shall by resolution adopted by a majority of the board determine that the interest of the county and the public interest or necessity demand the acquisition, construction, installation and equipment of pollution control facilities to be financed for or to be sold, leased or otherwise disposed of to persons, associations or corporations other than municipal corporations or other political subdivisions, whereupon the board shall order the submission of the proposition of issuing such revenue bonds for the purposes set forth in said resolution to the vote of the qualified electors of the county as defined in section 34-104, Idaho Code, at an election to be held subject to the provisions of section 34-106, Idaho Code. The declaration of public interest or necessity herein required and the provision for the holding of such election may be included within one and the same resolution, which resolution, in addition to such declaration of public interest or necessity, shall recite the objects and purposes for which the revenue bonds are proposed to be issued, the amount of principal of the revenue bonds, and the source of revenues pledged to the payment of said bonds.
Such resolution shall also fix the date upon which such election shall be held, subject to the provisions of section 34-106, Idaho Code, the manner of holding the same, which shall be in accordance with the provisions of title 34, Idaho Code, and the method of voting for or against the issuance of the revenue bonds. Such resolution shall designate the precincts and polling places. The county clerk shall appoint for each polling place, from each precinct from the electors thereof, the officers of such election, one (1) of whom shall act as clerk, who shall constitute a board of election for each polling place. The description of precincts may be made by reference to any order or orders of the board, or by reference to any previous order or resolution of the board or by detailed description of such precincts. Precincts established by the board may be consolidated for elections held hereunder. A notice of election shall be published by the county clerk once a week for two (2) consecutive weeks, the first publication shall be not less than twelve (12) days prior to the election, and the last publication of which shall be at least five (5) days prior to the date set for said election, in the newspaper of general circulation within the county in which legal notices of the county are customarily published, and no other or further notice of such election or publication of the names of election officers or of the precincts or polling places need be given or made.
The county clerk shall conduct the election in the manner prescribed by law for the holding of county elections to the extent the same shall apply. The returns thereof shall be canvassed and the results thereof declared as provided in chapter 12, title 34, Idaho Code.
In the event that it shall appear from said returns that a majority of the qualified electors of the county who shall have voted on any proposition submitted hereunder at such election voted in favor of such proposition, the county shall thereupon be authorized to issue and sell such revenue bonds of the county, all for the purpose or purposes and object or objects provided for in the proposition submitted hereunder and in the resolution therefor, and in the amount so provided.
