Any land or territory within the city which is not indicated on the zone map in any zone shall be classified in the same zone as that existing on the side of the street across from such unzoned land or territory, and the zone map shall thereupon be amended to indicate such zoning as herein required without additional procedure. Where uncertainty exists as to the zoning classification to be indicated on the map, or any other provision of this chapter, such zoning shall be determined by the commission by written decision.
