In order to classify, regulate and restrict the location of businesses and industries, and the location of buildings designed for specified uses; to regulate and limit the height and bulk of buildings hereafter erected or altered; to regulate and limit the intensity of the use of lot areas, and to regulate and determine the area of yards, courts and other open spaces within and surrounding such buildings, the village is hereby divided into nine classes of districts. The use, height and area regulations shall be uniform in each class of districts, and said districts shall be:

   C1 Commercial District

   C2 Commercial District

   C3 Central Commercial District

   ORIC Office/Research/Industrial/Commercial District

   PRI Public, Recreational and Institutional District

   R1 Wide Lot Single-Family Residential District

   R2 Single-Family (Detached) Residential District

   R3 Single-Family (Attached) Residential District

   R4 Multi-Family Residential District

(Ord. 2640, 5-23-95)

   A.   The boundaries of the districts mentioned in Section 10-6-1 are shown upon a map hereby made a part of this Zoning Title, which map is designated as the "Zoning District Map". The Zoning District Map and all the notations, references and other matters shown thereon shall be as much a part of this Zoning Title and have the same force and effect as if the notations, references and other information set forth thereon where all fully set forth or described herein, which Zoning District Map is properly attested, and is on file in the office of the Village Administrator. To the extent that the Zoning District Map conflicts with the text contained in this Zoning Code, however, the text shall prevail.

   B.   The boundaries of the River Forest Historic District have been overlaid on the Zoning District Map solely to recognize the significance the District holds for the Village and is for informational purposes only. There are no regulations in this Title which exclusively affect those properties located within the Historic District boundaries. The significance of the River Forest Historic District (entered in the National Register of Historic Places on August 26, 1977) lies primarily in the Village’s architecture, especially in those buildings embodying the revolutions in design developed in the late Nineteenth and early Twentieth Centuries by Frank Lloyd Wright and his contemporaries.

Where uncertainty exists with respect to the boundaries of the various districts as shown on the Zoning District Map, as hereinabove described, the following rules shall apply:

   A.   The district boundaries are either streets or alleys unless otherwise shown, and when the designations on the said Zoning District Map indicate that the various districts are approximately bounded by street or alley lines, said street or alley shall be construed to be the boundary of such district.

   B.   Where the district boundaries are not otherwise indicated and where the property has been or may hereafter be divided into blocks and lots, the district boundaries shall be construed to be lot lines, and where the designations on the Zoning District Map indicate that the various districts are approximately bounded by lot lines, said lot lines shall be construed to be the boundaries of such district, unless said boundaries are otherwise indicated on the Zoning District Map.

   C.   Where the district boundaries are not shown by streets or alleys, or lot or block lines, the district boundaries shall be determined solely by the dimensions shown on the Zoning District Map.

   D.   The Zoning Board of Appeals shall make the final determination on any question of district boundaries. (Ord. 2640, 5-23-95)
