Fences erected after passage of this Section that do not comply with all applicable provisions of this Section shall be considered illegal and shall be dismantled and removed by the property owner(s) at their expense.
5. 
Issuance of a permit by the City of Dardenne Prairie, Missouri, is verification that all of the provisions of this Section have been met, but this does not guarantee or constitute subdivision approval.
C. 
Design And Placement.
1. 
The maximum height for fencing, accompanying structures and decorative posts is six (6) feet, six (6) inches, except as noted elsewhere within this Section.
2. 
Fences/decorative posts must be constructed on or within the property lines; may not be placed in the State right-of-way without a State permit; and if they are constructed within the easement on the subject property, are subject to removal by the property owner or other authorized party without compensation or renumeration.
3. 
Fences/decorative posts may be located on any side or rear yard property line that does not abut a street.

Installation of the fence may not obstruct any manhole or inlet covers and must not impede/disturb the existing drainage patterns/swales or natural water flows on the subject property or adjacent properties.
5. 
Fencing built forward of the required lot setback line is prohibited, except in cases where more than one (1) side of the lot abuts a public street. In this case, the fence may project up to ten (10) feet over the building line only on the side yard that is adjacent to the street. Fencing within the front yard setback is prohibited.
6. 
Decorative posts less than thirty (30) inches in height may be placed in the front yard, provided they are no closer than two (2) feet to the property line. For purposes of this Section, "decorative posts" are defined as ornamental poles or stakes with attached chains, rope or other material that serve only aesthetic purposes.

All fencing in place prior to the effective date of this Section shall be considered legal non-conforming structures.
2. 
As long as a legal non-conforming fence is not replaced or relocated or the frame or structural supports are not altered in any manner that extends, enlarges or intensifies the non-conformity, the fence will be allowed to remain. If the fence is altered, then the fence must be brought into compliance with all applicable provisions of this Section.
F. 
Special Fencing Requirements.
1. 
Commercial bufferyard fencing.
a. 
Base material. The base material used to construct the fence must be rigid polyvinyl chloride (PVC) and the extruded product must adhere to the ASTM (American Society for Testing Materials) standards. The PVC used must be impact tested for durability and must be formulated to be stable in ultraviolet (UV) light. The material must also be "self-extinguishing", non-flammable with a flash temperature of not less than nine hundred degrees Fahrenheit (900°F).
b. 
Brackets and fasteners. Brackets and fasteners can be made of stainless steel, galvanized steel, brass or any other material fashioned for outdoor use. This is in order to provide better weathering and rust protection. This includes all nuts, bolts, screws and washers, as well as all hinge assemblies and latching mechanisms.
c. 
Internal dimensions. The PVC used must be of a weight and thickness that can support itself. The walls of each component of the fence must be thick enough to ensure that the piece will not bend or warp because of heat, cold, strong winds or any other external force. The wall thickness of each component should be matched to the size of the component used. The standard component sizes and thickness are listed below:

d. 
Posts. All line posts should be fully reinforced and set the minimum depth required to support a fence of the stated height. These details should be stated on the fence diagram. All posts should be topped with molded PVC caps that are complimentary to the style of the fence. Posts should be routed to receive rails.
e. 
Rails. Bottom rails should contain a stiffener channel for added strength and stability. A steel or aluminum channel may be used. Rails should be routed to receive pickets.
f. 
Pickets. The pickets used in the fence can be either ribbed or hollow and can be either flat sided or tongue and grove interlocking.
g. 
Gates. Should be fully reinforced so that the gate retains its shape and fit and can be fully opened and closed without difficulty.
h. 
Design. The design and color of the fence should be complementary to the other structures located on and around the site. Although chemical pigment may be added to some PVC compounds to give the fence color, any additives to the PVC material should not supersede the material standards previously stated in this document.
i. 
Configuration. The sizes and shapes of the pickets, rails and posts should not deviate from the standard sizes previously listed, unless necessary for a custom fence installation. For any deviation, a review of the fence schematic and prior approval will be required.
j. 
Aesthetic. All fencing materials must be contiguous; any fencing that is installed on a piece of property must be of the same material and design as the existing fence. If this is not possible, for instance, the material used to make the existing fence is no longer available, all existing fencing must be removed or altered so that it is the same as the new fence. Mixing of fence elements is not permitted i.e., connecting the twenty (20) foot span between two (2) sections of wood fencing with a chain-link fence.
2. 
Enclosures for pools, spas and hot tubs.
a. 
All swimming pools, hot tubs and spas shall be fully enclosed by a continuous fence with a minimum height of four (4) feet at its lowest point when measured from finished grade to the top of the fence. The maximum clearance between the finished grade and the bottom edge of the fence is two (2) inches.
b. 
All fencing used around pools, hot tubs and spas are required to have gates that open away from the pool structure and are self-closing and self-latching.
c. 
For all inground pools and for all aboveground pools that have a wall height of less than forty-eight (48) inches, when measured from finished grade to the lowest point of the structure, the fencing that encloses the pool will be separate from the pool itself and must meet the four (4) foot height requirement when measured on the side of the fence that faces away from the pool.
d. 
For all aboveground pools that have a wall height of forty-eight (48) inches or greater, the pool structure will be accepted as the barrier, if the minimum height can be reached without any additional constructs (fencing, railing, etc.) being added to the top of the pool structure.
e. 
If the pool comes equipped with a removable ladder, the ladder alone shall not constitute an acceptable alternative to the fencing requirements. When the pool structure qualifies as the barrier, the ladder access area must be enclosed with a fence at a minimum height of four (4) feet and have a self-closing, self-latching gate.
f. 
In addition to the requirements listed, all fencing used around any pool must comply with all applicable provisions of the current building codes as adopted in the City Code.
g. 
A fence must be completely constructed and installed in compliance with this Subsection within fifteen (15) days of the completion of construction or installation of any pool.
G. 
Exceptions.
1. 
Temporary protective fencing that is used to secure an area during active earth work (excavation, construction, grading) is permitted without the issuance of a fence permit.
2. 
Swimming pools, hot tubs, spas and other water features less than twenty-four (24) inches deep and less than two hundred fifty (250) square feet of surface area are not required to have fencing or protective barrier.
3. 
Hot tubs or spas with an approved safety cover.
4. 
Fencing that is installed as a structural construct or as a safety device (i.e. batting cages, backstops on ball fields, fencing on the top of a retaining wall or similar structure, etc.) is permitted without the issuance of a permit, however, it shall be shown as an improvement and is subject to review and approval by City staff.
5. 
The maximum height limit for fencing/decorative posts may be exceeded either:
a. 
With the approval of a conditional use permit, provided the following conditions apply: The increase in height shall in no way further obstruct vision for intersecting streets, driveways, sidewalks or other traffic areas. The fence shall be screened on its external side with adequate plants so as to maintain an attractive appearance to said side; or
b. 
Without a conditional use permit, if a fence with a height of greater than six (6) feet six (6) inches is required in order to maintain compliance with any current City ordinance.
H.
