§ 151.05 ZONING MAP.
   (A)   This chapter has no effect until the boundaries of the use districts are delineated on an Official Zoning Map, created pursuant to M.S. § 462.357, Subd. 1, as it may be amended from time to time, which, once it is adopted by ordinance after notice and hearing as provided in M.S. § 462.357, Subd. 3, as it may be amended from time to time, is hereby adopted by reference and declared to be a part of this chapter. This map shall be on permanent file and available for public inspection in the City Office. It shall be the responsibility of the Clerk or other person appointed by the City Council to administer this chapter to maintain and keep the map up to date.
   (B)   All property within the city shall have the zoning designation shown on the official zoning map. If there is any discrepancy or inconsistency between the official zoning map and any other map, ordinance or source which purports to indicate the zoning of property, the official zoning map shall take precedence. The provisions of this section shall not be interpreted to require the city to zone all properties within the city limits or to prevent zoning of only a portion of the city.
   (C)   Zoning district boundary lines shown on the official zoning map are intended to follow lot lines, the center lines of streets or alleys, the center lines of street or alleys projected, railroad right-of-way lines, the center of watercourses or the corporate limits of the city, unless otherwise specifically indicated.
