A. Establishment: The location and boundaries of the zoning districts defined in this UDO must be established by ordinance and shown on the City's official zoning map, which must be maintained under the direction of the Community Development Director.
B. Maintenance And Updates: The Community Development Director is responsible for directing revisions to the official zoning map to reflect its amendment as soon as possible after the effective date of zoning map amendments (rezonings).
C. District Boundaries: Zoning district boundary lines must be described by legal description or by a map that accompanies the ordinance establishing the district or amending the district boundaries. When a legal description is used, the zoning district boundary is deemed to extend to the centerline of abutting streets. When a map is used, district boundary lines must be established by dimensions, property lines, recorded lot lines, or the centerline of abutting streets, alleys, or railroad rights- of-way, as those features were of record at the time of adoption.
D. Map Interpretations: Where any uncertainty exists about a zoning boundary that was established by legal description, the legal description accompanying the amending ordinance governs. In other cases, the Community Development Director is authorized to make an interpretation in accordance with the procedures of section 10-15-10 of this title. The following rules apply to all map interpretations:
1. A boundary shown on the zoning map as approximately following the shoreline or centerline of a river, stream, lake or other watercourse will be construed as following the actual shoreline or centerline of the watercourse. If, subsequent to the establishment of the boundary, the shoreline or centerline of the watercourse should move as a result of natural processes (flooding, erosion, sedimentation, etc.), the boundary will be construed as moving with the shoreline or centerline of the watercourse.
2. A boundary shown on the zoning map as approximately following a ridge line or topographic contour line will be construed as following the actual ridge line or contour line. If, subsequent to the establishment of the boundary, the ridge line or contour line should move as a result of natural processes (erosion, slippage, subsidence, etc.), the boundary will be construed as moving with the ridge line or contour line.
3. A boundary shown on the zoning map as approximately following lot lines or other lot boundaries will be construed as following such lot lines or lot boundaries.
4. A boundary shown on the zoning map as approximately following a street or railroad right-of-way line will be construed as following the centerline of the street or railroad right-of-way.
5. A boundary shown on the zoning map as approximately following the boundary of an adjacent municipality will be construed as following that boundary.
6. A boundary shown on the zoning map as approximately parallel to, or as an apparent extension of, a feature described above will be construed as being actually parallel to, or an extension of, the feature.
E. Zoning Of Annexed Land: When land is annexed or otherwise brought into the zoning jurisdiction of the City, it may be classified in the RS District or assigned another zoning classification based on the comprehensive plan, existing land uses, any applicable annexation agreement and other relevant considerations.
