If the county board may do an act, incur a debt, appropriate money for a purpose, or exercise any other power or authority, only if authorized by a vote of the people, the question may be submitted at a special or general election, by a resolution specifying the matter or question to be voted upon. If the question is to authorize the appropriation of money, creation of a debt, or levy of a tax, it shall state the amount. Notice of the election shall be given as in the case of special elections. If the question submitted is adopted, the board shall pass an appropriate resolution to carry it into effect. In the election the form of the ballot shall be: "Shall (here state the substance of the resolution to be submitted)?, Yes ...... No......,". The county board may call a special county election upon a question to be held within 74 days after a resolution to that effect is adopted by the county board. Upon the adoption of the resolution the county auditor shall post and publish notices of the election, as required by section 204D.22, subdivisions 2 and 3. The election shall be conducted and the returns canvassed in the manner prescribed by sections 204D.20 to 204D.27, so far as practicable.
