For the purpose and provisions of this title, Prospect Heights, Illinois, is hereby organized into the following zoning district classifications:

 

(Ord. 0-77-27, 7-18-1977)

The boundaries of the zoning districts designated above are established as shown on the map entitled "official zoning map of Prospect Heights, Illinois", which map is attached as exhibit A to the ordinance codified herein and is made a part hereof, and shall have the same force and effect as if the zoning map, together with all notations, references, other information shown thereon, and any subsequent amendments were fully set forth and described herein. (Ord. 0-77-27, 7-18-1977)

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 line of sections, quarter sections, divisions of sections, tracts, or lots, or such lines extended or as 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 measured at right angles from the centerline of the street or highway and the length of frontage shall be in accordance with the dimensions shown on the map from section, quarter section, or division lines, or centerlines of streets, highways or railroad rights of way unless otherwise indicated.

   C.   Where a lot held in one ownership of record on the effective date hereof is divided by a district boundary line, the entire lot shall be construed to be within either district at owner's discretion, provided that this shall not apply if it increases the less restricted frontage of the lot by more than twenty five feet (25'). (Ord. 0-77-27, 7-18-1977)

All streets, alleys, public ways, waterways 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 alleys, streets, public ways and railroad rights of way, or waterways. Where the centerline of a street, alley, public way, waterway or a 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 centerline. (Ord. 0-77-27, 7-18-1977)

Any land hereafter annexed to the city of Prospect Heights shall automatically be zoned R-1. Any rezoning of newly annexed land or land to be annexed pursuant to an annexation agreement shall follow the procedures as outlined in chapter 10, "Administration And Enforcement", of this title. (Ord. 0-77-27, 7-18-1977)
