(2) Zoning district hierarchy. References in this chapter to less restrictive or more restrictive zoning districts refer to the base zoning districts established in this section and represent a progression from the AG District, the most restrictive base zoning district, to the II District, the least restrictive base zoning district. The OS District and the GW District are not included within the hierarchy.
(B) Zoning map. The boundaries of the zoning districts established by this chapter are shown on the “Official Zoning Map of Lake County, Illinois” which is a part of this chapter as fully as if it were set out in this chapter in detail. Original zoning district maps are maintained in the office of the Planning, Building and Development Director. In case of any dispute regarding the zoning classification of property subject to this chapter, the original maps maintained by the Planning, Building and Development Director shall control.
(1) Omitted land. It is the intent of this chapter that every part of unincorporated Lake County be included in one of the zoning districts established by this chapter. Any land located now or in the future outside of municipalities not shown to be included in a zoning district shall be deemed to be classified in the AG District.
(2) Additional land areas. Any land area that comes under the jurisdiction of this chapter shall automatically be classified in the AG District.
(3) District boundaries. The following rules govern interpretations regarding the location of zoning district boundaries.
(a) Municipal boundaries. Boundaries shown as following or approximately following the limits of any incorporated municipality shall be construed as following those limits.
(b) Streets. Unless otherwise indicated on the map, boundaries shown as following or approximately following streets shall be construed to follow the centerlines of those streets, except in the case of interstate highways. In the case of interstate highways, boundaries shall be construed as following rights-of-way lines.
(c) Property lines. Boundary lines shown as following or approximately following platted lot lines or other property lines shall be construed as following those lines, as shown on the county tax maps.
(d) Section lines. Boundaries shown as following or approximately following section lines, half-section lines, or quarter-section lines shall be construed as following those lines.
(e) Railroads. Unless otherwise indicated on the map, boundaries shown as following or approximately following railroad lines shall be construed to lie midway between the main tracks of those railroad lines.
(f) Shorelines. Boundaries shown as following or approximately following shorelines of any body of water shall be construed to follow the mean high waterlines of that body of water and, in the event of change in the mean high waterline, shall be construed as moving with the actual mean high waterline.
(g) Watercourses. Boundaries shown as following or approximately following the centerlines of streams, rivers, or other continuously flowing watercourses shall be construed as following the channel centerline of those watercourses taken at mean low water, and, in the event of a natural change in the location of those streams, rivers, or other watercourses, the zone boundary shall be construed as moving with the channel centerline.
(h) Map scale and distances. Boundaries shown as separated from, and parallel or approximately parallel to, any of the features listed in this subsection (B)(3) shall be construed to be parallel to those features and at the distances as are shown on the zoning district map. Distances not specifically indicated on the map shall be determined by the scale of the map.
