(A) Generally. The zoning districts set out in § 156.B.002, Zoning Districts Establishment, are shown on the Official Zoning Map, which is a part of this Zoning Ordinance as fully as if it were written out in detail. The Official Zoning Map is on file in the office of the Engineering Department and is available for inspection during regular business hours.
(B) Force and effect. The Official Zoning Map and all notations, references, and other information shown on it have the same force and effect as the text of this Zoning Ordinance.
(C) Status of the Zoning Map. The Official Zoning Map on file controls in the event of a conflict between the map on file and any other paper or digital reproduction of the map.
(D) Omitted or annexed land. Any area not shown as being included in a zoning district or annexed to the City of Marshalltown shall be deemed to be in the RL, Low-Density Residential zoning district unless the City Council changes the zoning district.
(E) Boundaries. Where there is uncertainty as to the boundaries of the districts as shown on the District Map of the city, the Zoning Administrator shall make a determination using the following criteria:
(1) Rights-of-way or easements. Where boundaries appear to follow existing streets, alleys, railroad tracks, utility lines, or similar features, the Zoning Administrator shall construe the zoning boundary to follow the center line of the rights-of-way or easement. Where the location of these features on the ground differs from that shown on the Official Zoning Map, the features on the ground control are shown approximately following street and alley lines, such street and alley lines shall be interpreted to be the boundaries.
(2) City limits. Where district boundaries are indicated as approximately following city limits, the Zoning Administrator shall consider the city limits as the district boundaries.
(3) Property lines. Where boundaries are indicated so that they approximately follow lot lines and are not more than 15 feet distant therefrom, such lot lines shall be interpreted to be the boundaries.
(4) Unsubdivided property. In unsubdivided property where a district boundary divides a parcel of land, the boundary shall be determined by the use of the scale appearing thereon.
(5) Watercourses. The Zoning Administrator shall construe boundaries shown as following, or approximately following, the centerline of drainageways, streams, water bodies, or other watercourses, as following the centerline. In the event of a natural change in the location of such streams or other watercourses, the Zoning Administrator shall construe the zoning district boundary as moving with the centerline.
(6) Vacation or abandonment. Whenever any street, alley, or other public way is vacated by the action of the City Council, the zoning district adjoining each side of such street, alley, or public way shall be extended automatically to the center of such vacated area.
(7) Ownership. When a lot held in one ownership is divided by a district boundary line, the entire lot will be construed to be within the district in which the majority of the lot is located.
(F) Conflicts resolved. In case of a conflict between the district boundaries on the Official Zoning Map and the zoning of property provided by an adopted ordinance, the ordinance controls. In case of doubt or dispute, the Board of Adjustment shall determine the boundary lines upon receiving an appeal from a ruling of the Zoning Administrator.
