[R.O. 2011 §400.370; Ord. No. 01-10 §1(8.01), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
A. 
The following residential districts are hereby established: "R-1", "R-2", "R-3", "R-4" and "R-5." Each of these districts is designed and intended to secure for the persons who reside there a comfortable, healthy, safe and pleasant environment in which to live, sheltered from incompatible and disruptive activities that properly belong in non-residential districts. Other objectives of some of these districts are explained in the remainder of this Section.
B. 
The "R-1" District is designed to accommodate single-family residential development in areas within the City's planning jurisdiction that are not served by public water or sewer facilities and that are not yet appropriate for development at higher densities.
C. 
The "R-2" and "R-3" Districts are designed primarily to accommodate single-family detached residential uses (other than mobile homes) at medium densities in areas served by public water and sewer facilities. These are residential districts in transition and can be considered to be "mixed use" residential neighborhoods with some businesses and commercial establishments also located within the same neighborhood by conditional use permit.
D. 
The "R-4" District is designed to accommodate single-family detached, two-family and multi-family dwelling units, as well as some types of mobile homes located within mobile home parks.
E. 
The "R-5" District is designed primarily to accommodate higher density multi-family developments.
[R.O. 2011 §400.380; Ord. No. 01-10 §1(8.03), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
A. 
The following business districts are hereby established: "B-1", "B-2", "B-2H", "B-3", "B-4" and "M-U." These districts are created to accomplish the purposes and serve the objectives set forth in the remainder of this Section.
B. 
The "B-1" (downtown business) District is designed to accommodate a wide variety of commercial activities (particularly those that are pedestrian oriented) that will result in the most intensive and attractive use of the City's former central business district.
C. 
The "B-2" and "B-2H" (community business) Districts are designed to accommodate business development on a scale that is less intensive than that permitted in a "B-1" District. A lesser intensity of development is achieved through setback, height and minimum lot size requirements that are more restrictive than those applicable to the "B-1" zone. The types of uses permissible in these zones are generally similar to the types permissible in a "B-1" zone, except that additional automobile-oriented businesses (e.g., drive-in banks and restaurants) not allowed in the "B-1" zone are permissible in these zones. The "B-2" and "B-2H" thus may provide a transition in some areas between a "B-1" zone and a residential zone or may provide for a smaller scale shopping that primarily serves one (1) neighborhood or area of the City. The dimensional restrictions in the zone are also designed in appropriate areas to encourage the renovation for commercial purposes of buildings that formerly were single-family residences. The only difference between the "B-2" and "B-2H" zones is the difference in height limitations spelled out in Section 400.670. Therefore all other references in this Chapter to the "B-2" District shall be deemed to include the "B-2H" District.
D. 
The "B-3" (general business) District is designed to accommodate the widest range of commercial activities.
E. 
The "B-4" (highway service) is designed to accommodate business activities primarily from and provide services primarily to the existing designated highways.
F. 
The "MU" (mixed use office/residential uses and uses that fall primarily within the corresponding classification in the Table of Permissible Uses (office, clerical, research, services, etc.)). It is intended that this zoning classification be applied primarily to residential areas because of land use conflicts, lack of access, obsolete buildings or structures, inadequate street widths or because of other market factors but remain viable as locations for single or multi-family residential developments, neighborhood businesses or offices. Such areas will also generally constitute transition or buffer zones between major arterials or more intensively developed commercial areas and residential districts.
[R.O. 2011 §400.390; Ord. No. 01-10 §1(8.05), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
The following districts are hereby established primarily to accommodate enterprises engaged in the manufacturing, processing, creating, repairing, renovating, painting, cleaning or assembling of goods, merchandise or equipment: "I-1" and "I-2." The performance standards set forth in Article XI place limitations on the characteristics of uses located in these districts. The limitations in the "I-1" District are more restrictive than those in the "I-2" District.

[R.O. 2011 §400.400; Ord. No. 01-10 §1(8.07), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
A. 
There is hereby created a public/semi-public zone district to allow for the siting of activities in the public domain, the expansion of North Central Missouri College and which shall be devoted to land uses intended to serve the public, either directly or indirectly, to permit orderly development of public facilities, utilities and schools and to promote the orderly establishments of certain institutional land uses.
B. 
The Planning Commission may require the provision of a buffer strip consisting of trees, shrubbery, fencing or other open space or buffer strip between land uses that appear to be in conflict as determined and interpreted by the Planning Commission.
[R.O. 2011 §400.405; Ord. No. 01-10 §1(8.08), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
A. 
There are hereby established twenty-four (24) different planned unit development ("PUD") districts as described in this Section. Each "PUD" District is designed to combine the characteristics of at least three (3) and possibly four (4) zoning districts.
1. 
One (1) element of each "PUD" District shall be the medium density residential element. Here there are two (2) possibilities, each one corresponding either to the "R-2" or "R-3" residential districts described in Section 400.370(C). Within that portion of the "PUD" zone that is developed for medium density residential purposes, all development must be in accordance with the regulations applicable to the medium density residential district to which the particular "PUD" zoning district corresponds (except that planned residential developments shall not be permissible).
2. 
A second (2nd) element of each "PUD" District shall be the higher density residential element. Here there are two (2) possibilities, each one corresponding either to the "R-4" or "R-5" zoning districts described in Sections 400.370(D) and (E) respectively. Within that portion of the "PUD" District that is developed for higher density residential purposes, all development must be in accordance with the regulations applicable to the higher density residential district to which the "PUD" District corresponds.
3. 
A third (3rd) element of each "PUD" District shall be the commercial element. Here there are three (3) possibilities, each one corresponding to one (1) of the following commercial districts identified in Section 400.380: "B-1", "B-2" or "MU." Within that portion of a "PUD" District that is developed for purposes permissible in a commercial district, all development must be in accordance with the regulations applicable to the commercial district to which the "PUD" District corresponds.
4. 
A manufacturing/processing element may be a fourth (4th) element of any "PUD" District. Here there are two (2) alternatives. The first (1st) is that uses permitted within the "I-1" District would be permitted within the "PUD" District. The second (2nd) alternative is that uses permitted only within the "I-1" or "I-2" Zoning Districts would not be permitted. If an "I-1" element is included, then within that portion of the "PUD" District that is developed for purposes permissible in an "I-1" District, all development must be in accordance with the regulations applicable to the "I-1" District.
B.

[R.O. 2011 §400.405; Ord. No. 01-10 §1(8.08), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
A. 
All plans submitted in support of permit applications shall be approved by the Planning and Zoning Board prior to the issuance of a building permit.
B. 
The plans for the proposed planned unit development shall indicate the particular portions of the lot that the developer intends to develop for higher density residential purposes, lower density residential purposes, purposes permissible in a commercial district (as applicable) and purposes permissible only in an "I-1" District (as applicable). For purposes of determining the substantive regulations that apply to the planned unit development, each portion of the lot so designated shall then be treated as if it were a separate district zoned to permit, respectively, higher density residential ("R-4" or "R-5"), lower density residential ("R-2" or "R-3"), commercial or "I-1" uses. However, only one (1) permit — a planned unit development permit — shall be issued to the entire development.
C. 
Within any lot developed as a planned unit development, not more than thirty-five percent (35%) of the total lot area may be developed for higher density residential purposes ("R-4" or "R-5" as applicable), not more than ten percent (10%) of the total lot area may be developed for purposes that are permissible only in a "B-1", "B-2" or "M-U" Zoning District (whichever corresponds to the "PUD" Zoning District in question) and not more than five percent (5%) of the total lot area may be developed for uses permissible only in the "I-1" Zoning District, assuming the "PUD" Zoning District allows such uses at all.
D. 
No area of less than five (5) contiguous acres may be zoned as a "PUD" District and then only upon the request of the owner or owners of all the property intended to be covered by such zone.
E. 
As indicated in the Table of Permissible Uses, a planned unit development is the only permissible use of a "PUD" zone and planned unit developments are permissible only in such zones.
[R.O. 2011 §400.410; Ord. No. 01-10 §1(8.09), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
The floodplain and floodway districts are hereby established as "overlay" districts, meaning that these districts overlay upon other districts and the land so encumbered may be used in a manner permitted in the underlying district only if and to the extent such use is also permitted in the applicable overlay district. The floodplain and floodway districts are further described in Part 1 of Article XVII of this Chapter.
[R.O. 2011 §400.415; Ord. No. 01-10 §1(8.10), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
This is an overlay district created by separate ordinance for the airport vicinity, Trenton, Missouri. Contact City Hall for a copy. This overlay zone protects the airport air rights from encroachment by land use activities of structures that would pose a hazard to aviation.
[R.O. 2011 §400.425; Ord. No. 01-10 §1(8.12), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
A. 
There shall be a map known and designed as the Official Zoning Map which shall show the boundaries of all zoning districts within the City's planning jurisdiction. This map shall be drawn on acetate or other durable material from which prints can be made, shall be dated and shall be kept in the Planning Department.
B. 
The Official Zoning Map dated April 9, 2001, is adopted and incorporated herein by reference. Amendments to this map shall be made and posted in accordance with Section 400.430.
C. 
Should the Official Zoning Map be lost, destroyed or damaged, the Administrator may have a new map drawn on acetate or other durable material from which prints can be made. No further Council authorization or action is required so long as no district boundaries are changed in this process.
[R.O. 2011 §400.430; Ord. No. 01-10 §1(8.13), 4-9-2001; Ord. No. 04-25 §1, 7-26-2004]
A. 
Amendments to the Official Zoning Map are accomplished using the same procedures that apply to other amendments to this Chapter as set forth in Article XXII.
B. 
The Zoning Administrator shall update the Official Zoning Map as soon as possible after amendments to it are adopted by the Council. Upon entering any such amendment on the map, the Administrator shall change the date of the map to indicate its latest revision. New prints of the updated map may then be issued.
C. 
No unauthorized person may alter or modify the Official Zoning Map.
D. 
The Planning Department shall keep copies of superseded prints of the Zoning Map for a historical reference.
