§ 159.096  ZONING DISTRICTS.
   (A)   Official Zoning Map.  The Planning Jurisdiction is hereby divided into zones, or districts, as shown on the Official Zoning Map which, together with all explanatory matter thereon, is hereby declared to be a part of this chapter.
      (1)   Identification Of Official Zoning Map.  The Official Zoning Map shall be identified by certification and bear the seal of the City under the following words: "This is to certify that this is the Official Zoning Map referred to in Article 7 of Ordinance Number 62-12-95 of the City of Noblesville, State of Indiana," together with the date of adoption of this chapter.  Certification  should be by the signature of the Mayor and attested by the City Clerk-Treasurer.  The title "Official Zoning Map" in large letters may be placed in an appropriate open space around the map or in the title block.
      (2)   Maintenance Of Official Zoning Map.  If in accordance with the provisions of this chapter changes are made in district boundaries or other matter portrayed on the Official Zoning Map, such changes shall be entered on the Official Zoning Map promptly after the amendment has been approved by the Common Council with an entry on the Official Zoning Map as follows: On     (date)      by official action of the Common Council, the following changes were made on the Official Zoning Map:                               , which entry shall be initialed by the Director or Chairman of the Plan Commission and attested by the City Clerk Treasurer.  No changes of any nature shall be made on the Official Zoning Map or matter shown thereon except in conformity with the procedures set forth in this chapter.  Any unauthorized change of any kind by a person or persons shall be considered a violation of this chapter and punishable as provided under § 159.999.
      (3)   Location Of Official Zoning Map.  Regardless of the existence of purported copies of the Official Zoning Map which from time to time may be published, the Official Zoning Map shall be located in the office of the Clerk-Treasurer of the City of Noblesville.  It shall be the final authority as to the current zoning status of land and water areas in the City, and its administrative jurisdictional area.

         Flood Hazard (FH) District
         Federal Hill Planned Development (FeHiPD) District
   (C)   Interpretation of District Sequence
      (1)   General Rule.  This chapter rejects as outdated and inappropriate the concept of hierarchical and cumulative zoning districts and, except as noted below, is based on the concept that each district should be designed to accomplish a specific purpose, to encourage a particular type of development, and to protect that development from being encroached upon by incompatible types of development.
      (2)   Special Rule.  Within the foregoing philosophy, however, it is recognized that, when different districts are juxtaposed, their differing characters may require special treatment to ameliorate incompatibilities that might otherwise result.  For this limited purpose, this chapter recognized the concept of "more restrictive" and "less restrictive" districts, and the districts established by this chapter shall be considered "more restrictive" or "less restrictive" in accordance with the following rules.
         (a)   The residential districts shall be deemed more restrictive than any nonresidential district.
         (b)   The SR District shall be deemed to be the most restrictive residential district and the R-5 District shall be deemed to be the least restrictive residential district, and the residential districts shall be deemed to become less restrictive as the district number increases.
         (c)   The commercial, industrial and special districts shall be deemed to be equally restrictive.
   (D)   Rules For Interpretation Of District Boundaries.  Where uncertainty exists with respect to the boundaries of districts as shown on the Official Zoning Map, the following rules shall apply:
      (1)   Boundaries indicated as approximately following the center lines of thoroughfares or highways, street lines or highway right-of-way lines, or alleys shall be construed to follow such center lines.
      (2)   Boundaries indicated as approximately following platted lot lines shall be construed as following such lot lines.
      (3)   Boundaries indicated as approximately following city limits shall be construed as following such city limits.
      (4)   Boundaries indicated as following railroad lines shall be construed to be midway between the main tracks.
      (5)   Boundaries indicated as following shore lines shall be construed to follow such shore lines; and in the event of change in the shoreline, shall be construed as moving with the actual shoreline.
      (6)   Boundaries indicated as approximately following the center lines of streams, rivers, canals, lakes, or other bodies of water shall be construed to follow such center lines, provided, however, when streams meander from the stream bed as it existed on the effective date of this chapter, the boundaries shall be construed as following the original stream bed, except for floodplain boundaries which are somewhat dependent on streams for their definition.
      (7)   Boundaries indicated as approximately following flood plain lines shall be construed to follow such contour lines.  In addition to the boundaries shown on the zone maps, the flood plain boundaries of minor ditches and streams may be designated as being 100 feet either side of the edge of the water at mean elevation, or the outer edges of a horizontal plane established at an elevation of five feet above the mean water level, whichever is the greater distance.  In this case, the stream, or ditch, shall be designated as one which flows at least 180 days of the year.
      (8)   Boundaries indicated as parallel to or extensions of features indicated in divisions (D)(1) thorugh (7) of this section shall be so controlled.  Distances not specifically indicated on the Official Zoning Map shall be determined by the scale of the map.
      (9)   Where physical or cultural features existing on the ground are at variance with those shown as the Official Zoning Map, or in other circumstances not covered by divisions (D)(1) through (6) of this section, the Board of Zoning Appeals shall interpret the boundaries.
      (10)   Where a district boundary line divides a lot which was in single ownership at the time of passage of this chapter, the Board of Zoning Appeals may permit, as a special exception, 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.
   (E)   Annexed Land.  All territory which may hereafter be annexed to the City of Noblesville shall be zoned consistent with the land use policy of the comprehensive plan and with the zoning district most similar to the zoning which was applicable prior to annexation, as long as that zoning is consistent with the comprehensive plan land use policy map.
   (F)   Zoning District Equivalency Table.  Zoning districts existing prior to the effective date of this chapter, but which are no longer a district described by this chapter, shall require a map amendment to an equivalent and appropriate district which is described in this chapter.  Additionally, districts newly created by this chapter, but which do not currently exist on the zoning map, may later be a part of the Zoning map subsequent to a map amendment.  Prior to the amendment of the zoning map for such purposes, the following Table 4 shall be used to establish the relationship between existing and new districts:
