All territory annexed to the city hereafter shall be temporarily classified for agricultural purposes only, until permanently zoned by the governing body of the city. The city planning and zoning commission shall, as soon as practicable after annexation of any of the territory to the city, institute proceedings on its own motion to give the newly annexed territory a permanent zoning, and the procedure to be followed shall be the same as is provided by law for the adoption of original zoning regulations.

The procedure for establishing the permanent zoning on any annexed territory shall be the same as is provided by law for the amendment of the zoning ordinance.

An application for any use or building, other than permitted by Agricultural District Regulations, shall be accompanied by a plat showing the size of the lot or tract of land being used, and the location of and the size and type of buildings to be constructed, and shall be referred to the city planning and zoning commission for consideration and recommendation to the governing body, after due consideration to the type of permanent zoning to be applied to the area, and upon such recommendation the governing body may grant or deny the permit as the facts may justify.
