   The boundaries of the zoning districts designated above are established as shown on the maps entitled “Official Zoning Map of Polo, Illinois,” dated August 4, 1986, which map is referred to herein and made a part hereof by reference and shall have the same force and effect as if the zoning map together with all its notations, references and other information shown thereon, were fully set forth and described herein.

(Ord. passed 8-4-86)

   When uncertainty exists with respect to the boundaries of the various districts as shown on the zoning map, the following rules shall apply:

   (A)   District boundary lines are either the centerlines of railroads, highways, streets, alleys or easements, or the boundary lines of sections, quarter-sections, divisions of sections, tracts or lots of such lines extended otherwise indicated.

   (B)   In areas not subdivided into lots and blocks, wherever a district is indicated as a strip adjacent to and paralleling a street or highway, the depth of such strips shall be in accordance with the dimensions shown on the map from section, quarter-section or division lines, of center lines of streets, highways or railroad right-of-way unless otherwise indicated.

   (C)   Where a lot held in one ownership and of record on August 4, 1986, is divided by a district boundary line, the entire lot shall be construed to be within the less restricted district, provided that this construction shall not apply if it increases the less restricted frontage of the lot by more than 25 feet.

(Ord. passed 8-4-86)

   All streets, alleys, public ways and railroad rights-of-way if not otherwise specifically designated shall be deemed to be in the same zone as the property immediately abutting on such alley, streets, public ways and railroad rights-of-way. Where the center line of a street, alley, public way or railroad right-of-way serves as a district boundary, the zoning of such areas, unless otherwise specifically designated, shall be deemed to be the same as that of the abutting property up to such center line.

(Ord. passed 8-4-86)

   Prior to the annexation of any territory to the city, a plan of zoning the area to be annexed shall be forwarded to the city by the Buildings and Grounds Committee. Upon approval of such plan for zoning, the area to be annexed, the City Council shall direct the Buildings and Grounds Committee to hold a public hearing in accordance with the regulations of § 152.139.
