The elected planning commission shall be governed by the appropriate provisions of either sections 64.510 to 64.695 or sections 64.800 to 64.905 according to the provisions whereby the county adopted county planning and zoning.  3. If a county commission does not call for an election as provided in subsection 2 of this section, the voters of the county may submit a petition, signed by five percent of the number of voters in the county voting at the last gubernatorial election, calling for an election to elect members to a county planning commission. Upon receipt of such a petition, the county commission shall make an order to provide for the election of a county planning commission, pursuant to subsection 2 of this section, at the next countywide election. ­­-------- (L. 1996 H.B. 1259)  Effective 4-12-96
