In order to carry out the intent, purposes and provisions of this Code, the Town of Normal is hereby divided into the following districts:

The location and boundaries of the districts provided in this Code as of December 28, 1978, the effective date of the ordinance adopting this Zoning Code (Chapter 15 of the Municipal Code of the Town of Normal, Illinois, 1969, as amended) are hereby established as shown on the Zoning Map, Town of Normal, and such map and all notations, references and other information shown thereon shall be the boundaries of the districts provided herein. Amendments to such map shall be by ordinance duly adopted by the corporate authority.

Annually, not later than March 31 of each year, the corporate authority shall, by resolution, cause the publication in pamphlet form of a revised Zoning Map, Town of Normal, indicating to the extent practicable all changes made during the preceding calendar year. The original Zoning Map, Town of Normal, shall be the final authority on the zoning status of land, buildings and other structure and land uses within the Town of Normal as of the effective date of the ordinance adopting this Code. The original Zoning Map, Town of Normal, or after the publication and effective date of an annual Revised Zoning Map, Town of Normal, the latest Revised Zoning Map of the Town of Normal in effect on a specific date shall raise a rebuttable presumption as to the zoning status of land, building or other land uses within the Town of Normal as of said date, rebuttable solely and exclusively by the provision of an ordinance duly adopted by the corporate authority after the effective date of this Code (or after the effective date of the Zoning Map, Town of Normal or after the effective date of any revision thereto).

One copy of the Zoning Map and thereafter, one copy of the current annual revision thereto is to be kept available for public inspection in the office of the Town Clerk. Such map shall be identified by the signature of the Mayor, attested by the Town Clerk and bearing the seal of the Town under the words: “This is to certify that this Zoning Map supersedes and replaces the Zoning Map adopted on (day of adoption of the map being replaced) and is part of Chapter 15 of the Municipal Code of the Town of Normal, Illinois, l969, as amended.”

1. Rules for Interpretation. Where uncertainty exists with respect to the boundaries of districts shown on the Zoning Map, the following rules shall apply:
   1. Boundaries indicated as approximately following the center lines of streets, highways, or alleys shall be construed to follow such center lines;
   2. Boundaries indicated as approximately following platted lot lines shall be construed as following such lot lines;
   3. Boundaries indicated as approximately following corporation limits shall be construed as following such corporate limits;
   4. Boundaries indicated as following railroad lines shall be construed to lie midway between the main tracks of such railroad lines;
   5. Boundaries indicated as approximately following the center line of streams, canals, creeks, or other bodies of water shall be construed to follow such center lines;
   6. Boundaries indicated as parallel to an extension of features indicated in (1) through (5) above shall be so construed.
   7. Where a district boundary divides a lot in single ownership at the time of the passage of this Code, the Zoning Code Administrator, upon request of such property owner submitted within 30 days of the adoption of this Code, may extend the least restrictive portion to such lot to the entire lot.
   8. Where, due to the scale, lack of detail, illegibility, or where physical features existing on the ground are at variance with those shown on the Zoning Map and there exists any uncertainty, contradiction or conflict as to the intended location of any boundary as shown thereon, the Zoning Code Administrator shall make an interpretation of said map upon request of any person and within a reasonable period. Any person aggrieved by such interpretation may appeal such interpretation to the Zoning Board of Appeals.
2. Annexed Land and Reverted Public Lands. The following shall apply to all property which is hereafter annexed by the Town of Normal, or any publicly owned land which is transferred to private ownership.
   1. All annexed property, without further action of the Town Council, shall automatically assume the classification of A-Agriculture unless and until otherwise classified by amendment.
   2. Whenever any street, alley or other public way is vacated by the Town of Normal, the zoning district adjoining each side of such street shall automatically, and without further action of the Town Council, be extended to the centerline of such street, alley or other public way existing prior to such vacation.
3. Replacement of the Zoning Map. In the event that the Zoning Map becomes damaged, destroyed, lost, or difficult to interpret because of the nature or number of changes and additions, the Town Council may by resolution adopt a new Zoning Map which shall supersede the prior map.
