[Ord. No. 7249 §1, 2-13-2006]
A. 
The boundaries of these Districts are indicated upon the Zoning District Map of the City of Florissant, which map is made a part of this Chapter. The said Zoning District Map of the City of Florissant and all the notations, references and other matters shown thereon shall be as much a part of this Chapter as if the notations, references and other matters set forth by said map were all fully described herein; which Zoning District Map is on file in the office of the City Clerk of the City of Florissant.
B. 
All territory which may hereafter be annexed to the City of Florissant shall retain the zoning classification or the Florissant zoning classification closest to that which it had prior to the annexation unless the zoning classification is affirmatively changed through a rezoning. Except as hereinafter provided:
1. 
No building shall be erected, converted, enlarged, reconstructed or structurally altered, nor shall any building or land be used for any purpose other than is permitted in the district in which such building or land is located.
2. 
No building shall be erected, converted, enlarged, reconstructed or altered to exceed the height limit herein established for the district in which such building is located.
3. 
No building shall be erected, converted, enlarged, reconstructed or altered except in conformity with the area regulations of the district in which such building is located.
4. 
The minimum yards and required off-street parking spaces and open spaces, including lot area per family requirement, for each and every building existing at the time of passage of this Chapter shall not be encroached upon or considered as yard or required off-street parking spaces or open space requirements for any other building.
5. 
Every building hereafter erected or structurally altered shall be located on a lot as herein defined and in no case shall there be more than one (1) main building on one (1) lot, except as provided elsewhere in this Chapter.
6. 
No land dedicated for roadway purposes, either in a public or private street or place, shall be used as a yard or as any part of the required lot area prescribed by this Chapter.
7. 
No building shall be erected or reconstructed nor shall it be enlarged to the extent of increasing the floor area by twenty-five percent (25%) or more, except when the existing structure as well as the addition conforms to the off-street parking and loading requirements of this Chapter.
8. 
Nothing contained in this Chapter shall prevent the use of land or require permits therefore for the raising of agricultural crops, orchards or forestry.
C. 
Whenever any street, alley or other public way is vacated by official action of the City Council or other public officials, the Zoning Districts adjoining each side of such street, alley or public way shall be automatically extended to the center of such vacation and all area included in the vacation shall then and thenceforth be subject to all regulations of the extended Districts.
D. 
More than one (1) industrial, commercial, multiple dwelling or institutional building may be erected upon a single lot or tract in districts where said uses are authorized, but the yards and open spaces required around the boundaries of the lot or tract shall not be encroached upon by any such buildings, nor shall there be any change in the intensity of use requirements. Also, a building may be erected upon more than one (1) lot in which event the front and rear building line must be observed but side lot lines need only be observed on each side of building.
[Ord. No. 7249 §1, 2-13-2006]
In the event that the Official Zoning Map becomes damaged, destroyed, lost or difficult to interpret because of the nature or number of changes made thereto, the City Council may by ordinance adopt a new Official Zoning Map which shall supersede the prior Official Zoning Map. The new Official Zoning Map may correct drafting or other errors or omissions on the prior Official Zoning Map. The new Official Zoning Map shall be identified by the signature of the Mayor attested by the City Clerk. Unless the prior Official Zoning Map has been lost or has been totally destroyed, the prior map or any significant parts thereof remaining shall be preserved together with all available records pertaining to its adoption or amendment.
[Ord. No. 7249 §1, 2-13-2006]
A. 
Where uncertainty exists with respect to the boundaries of any of the aforesaid Districts as shown on the Zoning Map, the following rules shall apply:
1. 
Where District boundaries are indicated as approximately following the centerline or street line of streets, the centerline or alley line of alleys or the centerlines or right-of-way lines of highways, such lines shall be construed to be such District boundaries.
2. 
Where District boundaries are so indicated that they are approximately parallel to the centerlines or street lines of streets, the centerlines or alley lines of alleys or the centerlines or right-of-way lines of highways, such District boundaries shall be construed as being parallel thereto and at such distance therefrom as indicated on the Zoning Map. If no distance is given, such dimension shall be determined by the use of the scale shown on said Zoning Map.
3. 
Where District boundaries are indicated as approximately following lot lines, such lot lines shall be construed to be said boundaries.

Where the boundary of a District follows a railroad line, such boundary shall be deemed to be located midway between the main tracks of said railroad line.

The regulations established by this Chapter within each Zoning District shall be minimum regulations for promoting and protecting the public health, safety and general welfare and shall be uniform for each class of land or building, dwellings and structures throughout each District. Where there are practical difficulties or unnecessary hardship in the way of carrying out the strict letter of this Chapter, the Board of Adjustment shall have power in passing upon appeals to vary or modify any rules, regulations or provisions of this Chapter so long as the intent and purposes of this Chapter shall be observed, public safety secured and substantial justice done.
[Ord. No. 7249 §1, 2-13-2006]

All rights or remedies of the City are expressly saved as to any and all violations of any previous Zoning Code or amendments thereto of the City and that have accrued at the time of the effective date of this Chapter and such accrued violation of previous Zoning Codes which would otherwise become non-conforming uses under this Article shall be considered as violations of this Chapter in the same manner that they were violations of prior Zoning Codes of the City.
