§ 59-5250. - Official Zoning Districts Map.
5250.1. Official Zoning Districts Map Established. The location and boundaries of the various districts, as defined herein, shall be established by ordinance, and shall be shown and delineated on the Official Zoning Districts Map of the City. The Planning Director shall maintain the Official Zoning Districts Map. The map may be divided into parts or sections; said parts may be separately maintained for identification purposes when adopting or amending the Official Zoning Districts Map for any reference to the Official Zoning Districts Map. The Official Zoning Districts Map may also be maintained as an electronic map.
5250.2. Effect of Zoning District Change. The reclassification of property to a new zoning district shall be an amendment of the Official Zoning Districts Map and shall be so recorded.
5250.3. Accretion by Vacation of Street or Alley. Whenever any street or alley is vacated, the particular district in which property fronting on that street or alley is located shall automatically be extended to the centerline of the vacated street or alley, except as provided elsewhere in this chapter. Said centerline shall then be considered as the property line for purposes of calculating the development regulations requirements of the individual zoning district.
5250.4. Delineation of Zoning District Boundaries.
A. Zoning district boundary lines shall be established by government or rectangular survey, metes and bounds description, or the legal description of a lot contained in a plat of record.
B. Where a property abuts a public or private street or alley right-of-way, the district boundary shall be considered to extend to the centerline of said right-of-way, whether or not the legal description of the adopted ordinance of rezoning includes said street.
C. For purposes of applying the development regulations of an individual zoning district, all such requirements shall be calculated from the appropriate right-of-way line delineating a street or alley. However, for calculating lot size requirements within the AA Zoning District, the boundaries shall be calculated from the centerline of abutting streets and roads. For calculating the lot size requirements for mobile home residential within the R-1 Zoning District, the boundaries shall be calculated from the centerline of abutting streets and roads.
5250.5. Interpretation of District Boundaries. When uncertainty exists as to the boundaries of the districts on the Official Zoning Districts Map, the following rules apply.
A. Boundaries indicated as approximately following the centerlines of streets, highways or alleys shall be construed to follow such centerlines.
B. Boundaries indicated as approximately following platted lot lines shall be construed as following such lot lines.
C. Boundaries indicated as approximately following City limits shall be construed as following such City limits.
D. Boundaries indicated as following railroad lines shall be construed to be midway between the main tracks.
E. Boundaries indicated as following shorelines shall be construed to follow such shorelines, and in the event of change in the shoreline, shall be construed as moving with the actual shoreline. Boundaries indicated as approximately following the centerlines of streams, rivers, canals, lakes, or other bodies of water shall be construed to follow such centerlines.
F. Boundaries indicated as parallel to, or extensions of, features indicated in Paragraphs A. through E. above, shall be so construed. The scale of the map shall determine distances not specifically indicated on the Official Zoning Districts Map.
G. Where physical features existing on the ground are at variance with those shown on the Official Zoning Districts Map, or in other circumstances not covered by Paragraphs A through F above, the Board of Adjustment shall interpret the district boundaries.
H. Where a district boundary line divides a lot that was in single ownership on the effective date of this chapter, the Board of Adjustment, upon application and public hearing, may permit, as a variance, the extension of the regulations for either portion of the lot, not to exceed 50 feet beyond the district line into the remaining portion of the lot.
