2. 
No accessory land use or development shall be established until a primary structure or use is established on the same lot. No accessory land use or development shall be allowed to continue after termination of the primary use or development on a lot.
3. 
In the event two (2) or more permitted, conditional or accessory uses are conducted on the same tract of land, each having different minimum area requirements, the minimum area regulations for the combined uses shall be the largest of the required minimum areas for each of the particular uses.
B. 
Approved Lots. Every building or complex of buildings erected or structurally altered after the effective date of this Chapter shall be located on a lot that meets the requirements of this Chapter and Subdivision Regulations. The open space requirements for the district in which each lot is located must likewise be met.
C. 
Minimum Lot Size. Land dedicated for street right-of-way shall not be included in computing minimum lot area for the purposes of this Chapter. However, if through dedication of street right-of-way, the area of any lot or parcel already established via the provisions of the Land Use and Subdivision Regulations is decreased below the minimum area required in the applicable zoning district, development rights shall not be denied.
D. 
Right-Of-Way Acquisitions. If any legal lot of record, because of the acquisition of right-of-way by the City or other governmental entity, is caused to fall below the minimum applicable setback, lot width, lot coverage or open space requirement established by the lot's zoning district, the lot shall not be considered a non-conforming lot and the minimum setback, lot width, lot coverage or open space requirements for that lot, if less than the applicable minimum standards, shall be those of the lot after such right-of-way acquisition. Any building or structure on such lot that, prior to the City's acquisition of right-of-way, would have been permitted to be expanded under the applicable setback, lot width, lot coverage or open space requirement may still be expanded or enlarged so long as the deviation from the requirement does not exceed twenty-five percent (25%) of the regulation or regulations in question.

A. 
Purpose. The general purpose of this Section is to regulate the placement, construction and modification of commercial wireless communications facilities, including towers, support structures, and antennas in order to protect the health, safety, morals and general welfare of the community, while at the same time encourage utilization of existing telecommunication towers, and other publicly and privately owned facilities to minimize the unnecessary proliferation of new facilities and to not unreasonably interfere with development of the competitive wireless telecommunications marketplace within the City of Wentzville. Specifically, this Section is intended to:
1. 
Provide for the appropriate location and development of wireless communications facilities and systems to serve the citizens and businesses of the City of Wentzville;
2. 
Minimize adverse visual impacts of wireless communications facilities through careful design, location, landscape screening, and innovative camouflage techniques;
3. 
Maximize the use of existing and new support structures so as to minimize the need to construct new or additional facilities;
4. 
Maximize the co-location of facilities on any new support structures and facilitate the fewest and least visible new support structures capable of achieving these objectives;
5. 
Ensure that any new wireless communications facility is located in an area compatible with the neighborhood or surrounding community to the extent possible;
6. 
Ensure that regulation of wireless communications facilities does not have the effect of prohibiting the provision of personal wireless services, and does not unreasonably discriminate among functionally equivalent providers of such service.

h. 
That the design of the wireless communications facilities, including ground layout, maximally reduces visual degradation and otherwise complies with provisions and intent of this Section.
i. 
That the proposal minimizes the number and/or height and visibility of support structures that will be required in the area. Where alternate technology or design exists or is reasonably available that would satisfy the general need for the proposal, this factor is ordinarily not satisfied;
j. 
That the applicant has not previously failed to take advantage of reasonably available shared use opportunities or procedures provided by this Section or otherwise;
k. 
That no land owned by any agency of the Federal or State Government, or by any political subdivision of the State, is available for locating the wireless communications facility.
7. 
Performance guarantee. Upon final approval of the conditional use permit, the applicant shall deposit with the Community Development Department a bond, or other form of security acceptable to the City as to type of security and the form and manner of execution in an amount to insure performance of certain obligations of the applicant to make improvements shown upon the approved plan or attested to in any of the accompanying documents pursuant to Section 405.435. Improvements that are to be guaranteed by escrow are as follows, but shall not be limited to: required fencing, landscaping, and access roads/public roadway extensions.
8. 
RF engineer certification required — additional studies. The City may require, at the expense of the applicant, any additional studies or the hiring of an external consultant, including technical and legal services, to review exhibits and/or other requirements in accordance with this Section. Applications for a new tower shall be considered only after a letter, certified by a radio frequency engineer under oath, stating that the planned telecommunication equipment cannot be accommodated on an existing or already approved support structure that is capable of shared use and providing facts including:
a. 
All alternatives considered; and
b. 
Precise cost estimates where cost is a basis for the determination clearly demonstrating one (1) or more of the following conditions:
(1) 
Planned telecommunications equipment would exceed the structural capacity of an existing or approved support structure, and the support structure cannot be reinforced to accommodate planned telecommunication equipment at a reasonable cost;
(2) 
Planned telecommunications equipment will cause radio frequency interference with other existing or planned telecommunications equipment for that support structure and the interference cannot be prevented at a reasonable cost;
(3) 
Existing or approved support structures do not have space on which the planned telecommunications equipment can be placed so it can function effectively and at least in parity with other similar telecommunications equipment in place or approved by the City or other area jurisdictions; or
(4) 
Other reasons that make it impractical and not feasible to place the telecommunications equipment planned by the applicant on an existing or approved support structure.
H. 
Removal Of Obsolete Towers. Any tower that is no longer in use for commercial communication purposes shall be removed at the owner's expense. The owner shall provide the City with a copy of the notice to the FCC of the intent to cease operations and shall be given ninety (90) days from the date of ceasing operations to remove the obsolete tower and accessory structures.

The provision of traffic control or security personnel to ensure the public safety and convenience;

The provision of liability and personal injury insurance in the forms and amounts that the City finds necessary to protect the safety and general welfare of the community;

Limitations and conditions on signs;
