   A.   General Rule: This title rejects as outdated and inappropriate the concept of hierarchical and cumulative zoning districts and, except as noted below, is based on the concept that each district should be designed to accomplish a specific purpose, to encourage a particular type of development, and to protect that development from being encroached upon by incompatible types of development.

   B.   Special Rule: Within the foregoing philosophy, however, it is recognized that, when different districts are juxtaposed, their differing characters may require special treatment to ameliorate incompatibilities that might otherwise result. For this limited purpose, this title recognizes the concept of "more restrictive" and "less restrictive" districts, and the districts established by this title shall be considered "more restrictive" or "less restrictive" in accordance with the following rules:

      1.   The residential districts shall be deemed to be more restrictive than any nonresidential district;

      2.   The R-1 single-family residential district shall be deemed to be the most restrictive residential district and the R-4 central core residential district shall be deemed to be the least restrictive residential district, and the residential districts shall be deemed to become less restrictive as the district number increases;

      3.   The MH-1 mobile home park district shall be deemed to be more restrictive than any nonresidential district but less restrictive than any residential district;

      4.   The commercial districts shall be deemed to become less restrictive as the district number increases;

      5.   The I-1 institutional district shall be deemed to be more restrictive than the manufacturing districts but less restrictive than any residential district; and

      6.   The M-2 general manufacturing district shall be deemed to be less restrictive than any other district. (Ord. Z-8-98, 9-21-1998)

All territory hereafter annexed to the city of Des Plaines shall, at the time of annexation, be rezoned to the appropriate district classification described herein. (Ord. Z-8-98, 9-21-1998)

   A.   Map Incorporated: The location and boundaries of the zoning districts established by this title are as shown on a map entitled "Zoning Map Of The City Of Des Plaines, Illinois", hereafter referred to as the zoning map, which is by this reference incorporated as part of this title. All notations, references, and other information shown on the zoning map, and all amendments thereto, shall be as much a part of this title as if specifically set forth and literally described herein.

   B.   Omitted Land: It is the intent of this title that the entire area of the city, including all land and water areas, be included in the districts established by this title. Any area lying within the city but not shown on the zoning map as being included in a district shall be deemed to be, and is hereby classified as being within the R-1 single-family residential district.

   C.   District Boundaries: In the event that any uncertainty exists with respect to the intended boundaries of the various districts as shown on the zoning map, the following rules shall apply:

      1.   The district boundaries are the centerlines of highways, streets, alleys, waterways, railroads, and other rights of way unless otherwise indicated. When the designation of a boundary line on the zoning map coincides with the location of any such right of way, the centerline of such right of way shall be construed to be the boundary of such district;

      2.   When a district boundary does not coincide with the location of the centerline of any right of way but does coincide with a lot line, such lot line shall be construed to be the boundary of such district; and

      3.   When a district boundary does not coincide with the location of the centerline of any right of way or a lot line, the district boundary shall be determined by the use of the scale shown on the zoning map.

   D.   Maintenance And Availability Of Official Zoning Map: The official copy of the zoning map shall be maintained by the zoning administrator and shall be available for public inspection during city business hours at the department of community and economic development. Any amendment to zoning district boundaries or any change in any other information shown on the zoning map made by amendment to this title shall be indicated on the official copy of the zoning map.

   E.   Availability Of Zoning Map: A revised, up to date copy of the official zoning map, certified as to being inclusive of all amendments and drawn to a convenient scale, shall be published from time to time and made available for sale. (Ord. Z-8-98, 9-21-1998)
