For the purpose of this chapter, the city and the territory within the extraterritorial jurisdiction of the Plan Commission are hereby divided into eight categories of zoning districts as follows:

      A      Agricultural

      R-1      One-Family Residential

      R-2      One- and Two-Family Residential

      R-3      Multi-Family Residential

      B-1      Neighborhood Business

      B-2      Community Business

      M      General Manufacturing

(Ord., passed - -79)

   The several districts and boundaries thereof are hereby adopted and established as shown on the Zoning Map of the city, which map, together with all notations, references, data, district boundaries and other information shown thereon shall be and are hereby made a part of this chapter. The Zoning Map, properly attested, shall be and remain on file in the office of the Zoning Inspector.

(Ord., passed - -79)

   (A)   Except where referenced on the map to a street or alley lines or other designated line by dimensions shown on the map, the district boundary lines follow lot lines or the center lines of streets or alleys as they existed at the time of the adoption of this chapter; but where a district line obviously does not coincide with the lot lines or such center lines or where it is not designated by dimensions, it shall be determined by scaling.

   (B)   All questions concerning the exact location of district boundary lines shall be determined by the Board according to rules and regulations which may be adopted by it.

(Ord., passed - -79)

   Where a district boundary line established in this subchapter or as shown on the Zoning Map divides a lot which was in single ownership at the time of enactment of this chapter, the use authorized thereon and the other district requirements applying to the least restricted portion of such lot under this chapter shall be considered as extending to the entire lot, provided the more restricted portion of such lot is entirely within 25 feet of the dividing district boundary line. The use so extended shall be deemed to be conforming.

(Ord., passed - -79)

   Whenever any street, alley or other public way is vacated by official action as provided by law, the zoning district adjoining the side of such public way shall be extended automatically, depending on the side or sides to which such lands revert, to include the right-of-way thus vacated, which shall henceforth be subject to all regulations of the extended district or districts.

(Ord., passed - -79)

   In every case where property has not been specifically included within a district, the same is hereby declared to be in R-1 District. Territory included within the extraterritorial jurisdiction of the Plan Commission subsequent to the effective date of this chapter shall upon the effective date of such inclusion become a part of the A District. Such districting shall be temporary, and the Plan Commission shall recommend to the Common Council, within a period of not to exceed six months from the effective date of such inclusion, a final zoning districting of such property.
