Missouri Revised Statutes Title VII. Cities, Towns and Villages § 89.145. Peripheral zoning by certain cities--approval by county commission, hearing, notice--termination

1. Any constitutional charter city having a population of more than thirty-five thousand inhabitants, located in any county of the first class not having a charter form of government or in any county of the second class, may, by ordinance, adopt and enforce any and all regulations governing zoning, planning, subdivision and building within all unincorporated area extending up to two miles outward from the corporate limits of the city if the city has a zoning commission and a board of adjustment established pursuant to sections 89.010 to 89.140. When authorized by ordinance, the zoning commission and the board of adjustment of the city shall have the same powers within the above county as they have within the corporate limits of the city.

2. The ordinances, before passage, must be approved by order of a majority of the county commission of the county in which the city is located and the ordinances shall not be more, but may be less, restrictive than the ordinances governing zoning, planning, subdivision and building within the corporate limits of the city. Before the approval of the ordinance, the county commission shall hold at least one public hearing thereon, fourteen days' notice of the time and place of which shall be published in at least one newspaper having general circulation within the county; the notice of such hearing shall also be posted at least fourteen days in advance thereof in one or more public areas of the courthouse of the county. Such hearing may be adjourned from time to time.

3. In the event the county in which such city is located creates a county planning commission and the planning commission adopts an official master plan for the unincorporated areas of the county in accordance with the authority granted by sections 64.211 to 64.295 or by sections 64.510 to 64.690, the authority granted such constitutional charter city under the terms of this section shall terminate.
