§ 2.30. Boundaries of the District.

The boundaries of zoning districts, as shown on the zoning map, unless otherwise shown by dimensions from street lines or other designated lines, follow the center of the streets or alleys or lot lines, and such lines extended and the corporate limits of the city as they exist at the time of adoption of this Ordinance.

Where a district boundary line, as established in the above paragraph or as shown on the zoning map, divides a lot which was in single ownership and of record at the time of enactment of this Ordinance, a district boundary shall be fixed from the scale of the zoning map. The use authorized thereon and the other district requirements applying to the most restricted portion of such lot shall be considered as extending to the entire lot. The use so extended shall be deemed to be conforming.

All street and alley rights-of-way, if not otherwise specifically designated, shall be deemed to be in the same zone as the property immediately abutting upon such street and alley rights-of-way. Where the centerline of a street or alley serves as a district boundary, the zoning of such street or alley, unless otherwise specifically designated, shall be deemed to be the same as that of the abutting property up to such centerline.

Questions concerning the exact location of district boundary lines shall be determined by the zoning board of appeals after recommendation from the planning commission, according to rules and regulations which may be adopted by it.
