4.1.2   Official zoning atlas.  The land areas subject to these land development regulations are hereby divided into zoning districts as set out in this article above and as shown on the official zoning atlas of the county. The official zoning atlas, which may consist of one or more maps, together with all explanatory material shown therein is hereby adopted by reference and declared to be part of these land development regulations. The official zoning atlas is and shall remain on file in the office of the land development regulation administrator. The official zoning atlas shall be identified by the signature of the chairman of the board of county commissioners and attested by the clerk of the circuit court of the county. 
If, in accordance with the provisions of these land development regulations, changes are made in district boundaries or other subject matter portrayed on the official zoning atlas by the land development regulation administrator, such changes shall be made on the official zoning atlas promptly after the amendment has been adopted.
All changes made on the official zoning atlas or matter shown thereon shall be in conformity with the procedures set forth in these land development regulations.
The official zoning atlas, which shall be located in a designated place easily accessible to the public, shall be the final authority as to the current zoning status of land and water areas, as well as, buildings and other structures in areas subject to these land development regulations.
Prior zoning atlases or remaining portions thereof, which have had the force and effect of official zoning maps or atlases for areas subject to these land development regulations, shall be retained as a public record and as a guide to the historical zoning of land and water areas.
4.1.3   Rules for interpretation of district boundaries.   
4.1.3.1   [Applicability.]  District regulations extend to all portions of districts surrounded by boundaries. Except as otherwise specifically provided, district symbols or names shown within district boundaries on the Official Zoning Atlas indicate that district regulations pertaining to the district extend throughout the entire area surrounded by the boundary line. 
4.1.3.2   Rules where uncertainty exists.  Where uncertainty exists as to the boundaries of districts as shown on the official zoning atlas, the following rules shall apply: 
1.   Centerlines.  Boundaries shown as approximately following the centerlines of dedicated streets, highways, alleys, or rights-of-way shall be construed as following such center lines as they exist on the ground, except where variation of actual location from mapped location would change the zoning status of a lot or parcel, in which case the boundary shall be interpreted in such a manner as to avoid changing the zoning status of any lot or parcel. In case of a street vacation, the boundary shall be construed as remaining in its location except where ownership of the vacated street is divided other than at its center, in which case the boundary shall be construed as moving with the ownership. 
2.   Lot lines.  Boundaries shown as approximately following lot lines or public property lines shall be construed as following such lines; provided, however, that where such boundaries are adjacent to a dedicated street, alley, highway, or right-of-way and the zoning status of the street, highway, alley, or right-of-way is not indicated, the boundaries shall be construed as running to the middle of the street, highway, alley, or right-of-way. In the event of street vacation, interpretation shall be as provided in [subsection] 1. above. 
3.   City or town limits.  Boundaries shown as approximately following city or town limits shall be construed to follow such city or town limits. 
4.   Railroad tracks.  Boundaries shown as following railroad tracks shall be construed to be midway between the main tracks. 
5.   Mean high water lines; centerlines of streams, canals, lakes, or other bodies of water.  Boundaries indicated as following mean high water lines or centerlines of streams, canals, lakes, or other bodies of water shall be construed as following such mean high water lines or centerlines. In case of a change in mean high water line, or of the course or extent of bodies of water, the boundaries shall be construed to move with the change, except where such move would change the zoning status of a lot or parcel. In such case, the boundary shall be interpreted in a manner as to avoid changing the zoning status of any lot or parcel. 
6.   Body of water.  Boundaries shown as entering any body of water but not continuing to intersection with other zoning boundaries or with the limits of jurisdiction of board of county commissioners shall be construed to continue in the direction in which they enter the body of water and intersection with another zoning boundary or with the limits of jurisdiction of the board of county commissioners. 
7.   Boundaries parallel.  Boundaries shown as parallel to or extensions of features indicated in [subsections] 1. through 6, above shall be construed to be parallel to or extensions of such features. 
8.   Measurement of district boundaries.  Distances not specifically shown on the official zoning atlas shall be determined by the scale of the map showing the property in question. 
4.1.3.3   Cases not covered by section 4.1.3.2.  In cases not covered by section 4.1.3.2 above, the land development regulation administrator shall interpret the official zoning atlas in accord with the intent and purpose of these land development regulations. Appeal from the interpretation of the land development regulation administrator shall be only to the board of adjustment in conformity with article 12 of these land development regulations. 
4.1.4.   Schedule of district regulations.  The restrictions and controls intended to regulate development in each zoning district are set forth in the schedule of district regulations within this article and are supplemented by section 4-2, Supplementary district regulations, and section 2.3, Non-conformities. 
4.1.5.   Application of district regulations.  The regulations set by these land development regulations within each district shall be minimum or maximum limitations, as appropriate to the use, and shall apply uniformly to each class or kind of structure, use, land, or water. Except as hereinafter provided: 
4.1.5.1   Zoning affects use or occupancy.  No structure, land, or water shall hereafter be used or occupied, and no structure or part thereof shall hereafter be erected, constructed, reconstructed, located, moved, or structurally altered except in conformity with the regulations specified in these land development regulations for the district in which it is located. 
4.1.5.2   Zoning affects height of structures, population density, lot coverage, yards, and open spaces.  No structure shall hereafter be erected or altered: 
1.   To exceed height, bulk, or floor area;
2.   To provide a greater number of dwelling units per acre;
3.   To provide less lot area per dwelling unit or to occupy a smaller lot; or
4.   To occupy a greater percentage of lot area; or to provide narrower or smaller yards, courts, or open spaces; or lesser separation between buildings or structures or portions of buildings or structures, than herein required; or in any other manner contrary to the provisions of these land development regulations.
4.1.5.3   Multiple use of required space prohibited.  No part of a required yard or other required open space, or off-street parking or off-street loading space, provided in connection with one structure or use shall be included as meeting the requirements for any other structure or use, except where specific provision is made in these land development regulations. 
4.1.5.4   Reduction of lot area prohibited.  No lot or yard existing at the effective date of these land development regulations shall thereafter be reduced in dimension or area below the minimum requirements set forth herein, except by reason of a portion being acquired for public use in any manner such as dedication, condemnation or purchase. Lots or yards created after the effective date of these land development regulations shall meet at least the minimum requirements established by these land development regulations.

No separate accessory building shall be located within five feet of any building.
4.2.5   Alcoholic beverages.  Indications in the schedule of district regulations that the sale of alcoholic beverages is permitted in any zoning district shall not in any way be deemed to limit, qualify, or repeal any other local regulations or regulations of the State of Florida relating to the licensing, dispensing, or sale of such beverages or the location of alcoholic beverage establishments. Notwithstanding anything herein to the contrary, no alcoholic beverage shall be consumed or permitted to be consumed on or about the premises of any commercial establishment located within 500 feet of any school, church, synagogue, or house of worship.

5.   An individual speaker shall be provided for each vehicle. All speakers shall be equipped with sufficient cord to permit the speaker to be placed inside the vehicle. Speakers must not be audible beyond the boundaries of the theater property lines.
4.2.8   Erection of more than one principal structure on a platted lot.  Whenever any land has been subdivided, whether recorded, unrecorded or by special permit for land divisions more than ten acres in size but less than 20 acres in size (refer to section 14.14), a building permit for the construction of a building or other principal structure (excluding commercial buildings under common ownership or unified control) shall not be issued for any such structure on less than a lot as platted within such subdivision or land divisions more than ten acres in size but less than 20 acres in size. (Refer to section 14.14.) This provision shall not apply to special family lots as provided in section 14.9 herein. 
(Ord. No. 2003-20, 1, 4-17-03)
4.2.9   Future land use plan amendment for public buildings and facilities.  Except as stated herein, public buildings and facilities, which do not meet the definition of "essential services" as stated in article 14 of these land development regulations, shall require an amendment to the future land use plan map of the county's comprehensive plan to "public land use," prior to consideration for approval as a special permit. 
Until such time as the county's comprehensive plan is amended in accordance with F.S. 163.377(6)(a) and 235.19(4), regarding school siting and selection, public schools shall require an amendment to the future land use plan map of the county's comprehensive plan to "public land use" prior to siting and construction of the public school. After such amendment, public elementary, middle and high schools sitings are not required to first have a "public land use" classification on the county's future land use plan map prior to the location of the school.
Subsequent to the county's comprehensive plan being amended in accordance with the above stated sections of Florida law, public schools sites and facilities shall be selected and sited as allowable within the individual zoning districts as provided within this article. In addition, prior to the siting and construction of a school or school facility a site and development plan (including a concurrency assessment) shall be reviewed and approved for compliance with the county's comprehensive plan and these land development regulations by the planning and zoning board (refer to section 14.3 of these land development regulations). Public or private high schools, junior or community colleges, colleges and universities if not located within the Commercial, General and Commercial, Intensive districts, may be located within Agricultural, Rural Residential, Residential Single Family, Residential Single Family/Mobile Home, Light Industrial and Industrial zoning districts after amending the future land use plan map of the county's comprehensive plan to "public land use" and review and approval of a site and development plan by the planning and zoning board. (Refer to section 14.13.)
4.2.10   Exclusions from height limitations.  The height limitations contained in the schedule of district regulations do not apply to spires, belfries, cupolas, antennas, water tanks, ventilators, chimneys, elevator shaft enclosures, airport control towers, observation towers, telecommunications towers or other appurtenances usually required to be placed above the roof level and, excepting airport control towers and observation towers, not intended for human occupancy; however, the heights of these structures or appurtenances thereto shall not exceed any height limitations prescribed by the Federal Aviation Agency, Florida Department of Transportation or airport zoning regulations within the flight-approach zone of airports. 
4.2.11   Fallout shelters.  Fallout shelters are permitted in all zoning districts. Individual structures in residential districts shall be considered as accessory structures. 
4.2.12   Fences, walls, and hedges.  Notwithstanding other provisions of these land development regulations, fences, walls, and hedges may be permitted in any required yard or along the edge of any yard; provided that no solid fence, solid wall, or hedge located within the required front yard shall constitute an obstruction to visibility between two and one-half and six feet above the centerline grade of the adjacent street. 
4.2.13   Landscaped buffer areas.  The use of properly planted and maintained buffer areas may reduce and ease potential incompatibility between or among different uses of land in proximity to each other. 
4.2.13.1   Requirements.  Where these land development regulations require a landscaped buffer area, the following requirements shall be met: 
1.   The landscaped buffer area width shall be measured at right angles to property lines and shall be established along the entire length of and contiguous to the designated property line or lines.
2.   The area shall be so designed, planted, and maintained as to be 80 percent or more opaque between two and six feet above average ground level when viewed horizontally; provided, however, that plantings located in the required front yard shall not exceed two and one-half feet in height.
3.   Types and numbers of plantings for landscaped buffers shall be submitted with application for building permit. No building permit shall be issued without such data, where these land development regulations require a landscaped buffer area or areas.
4.   Plantings shall be of a size and type which will insure the meeting of the 80 percent opacity requirement within no longer than 12 months of the date of first planting. Where questions may arise as to the suitability of proposed plant materials to meet this requirement, final determination of suitability shall be made by the land development regulation administrator.
5.   The remainder of the required landscaped buffer area not covered by planting shall be landscaped with grass, ground cover, or other landscape treatment; except as otherwise provided herein, structures including buildings and off-street parking and loading areas shall not be located in any required landscaped buffer area.
6.   The landscaped buffer area shall be maintained by the property owner and successors and continued so long as the main use continues. Failure to maintain the landscaped buffer area as set out above shall be a violation of these land development regulations.
4.2.13.2   Substitution for landscaped buffer area.  Except when otherwise specifically provided by these land development regulations, a six-foot-high masonry or wood opaque structure may be substituted for the six-foot-high planted buffer within these supplementary regulations; provided, however, that where the masonry or wood opaque structure is located in the required front yard, it shall not exceed two and one-half feet in height. 
4.2.13.3   Waiver by land development regulation administrator.  When the land development regulation administrator finds that the public safety requires, he or she may waive or modify the buffer requirements set out in section 4.2 at street and alley frontages adjacent to any entrance; the finding of the land development regulation administrator shall be in writing and shall be filed with the approved building permit. The finding shall demonstrate that the buffer is not required for a certain number of feet back from the street or alley entrance in order to afford protection to pedestrian or vehicular traffic entering or leaving the lot on which the landscaped buffer area is required by these land development regulations. 
4.2.13.4   Waiver by board of adjustment.  Where by the terms of these land development regulations a non-residential use is required to provide a landscaped buffer along a property line which is contiguous to another non-residential use, the board of adjustment may waive the landscaped buffer requirements if evidence is presented to the board that the buffer will serve no useful purpose. Such evidence shall be heard in the same manner as a request for other variances, and adjoining property owners must be notified in writing of the board of adjustment meeting when the request will be heard. 
4.2.13.5   Application where these land development regulations set out different requirements.  In those instances where these land development regulations set out a different buffering requirement (e.g., greater height of landscaped buffer, or a different type of buffer), then the specific provisions of these land development regulations applicable to the particular type of use shall govern. 
4.2.14   Minimum living area.  No one-family, two-family, or multiple-family dwelling shall be erected with less than 450 square feet of floor area devoted to living space per dwelling unit, exclusive of the area of any open porch or attached garage or similar space not suited or intended for occupancy as living quarters. The board of adjustment may waive the minimum living area requirements if evidence is presented to the board of adjustment that such a waiver will not adversely affect the public interest or the character of the surrounding neighborhood. Such evidence shall be heard in the same manner as other variances, and adjoining property owners must be notified in writing of the board of adjustment meeting when the request will be heard. 
4.2.15   Mobile home--Replacement of existing mobile homes.  For the purposes of these land development regulations, the phrase existing mobile homes shall mean mobile homes which existed as of the effective date of adoption or amendment of these land development regulations. In those districts which do not permit the erection of new mobile homes but do permit existing mobile homes as a principal use, such existing mobile homes may be removed and replaced by another mobile home, provided: 
1.   That a period of 12 consecutive months does not elapse between the removal of one mobile home and the erection of another mobile home. The land development regulation administrator may permit an additional 12-month period subject to the request being made by the applicant prior to the expiration of the initial 12-month period.
4.2.16   Moving of buildings and structures.  No building or structure shall be moved from one lot to another lot, or moved to another location on the same lot, unless such building or structure shall thereafter conform to all of the applicable provisions of these land development regulations and to all other regulations and ordinances of the county. 
4.2.17   Off-street parking and loading.  It is the intent of these land development regulations that the public interest, welfare, and safety requires that buildings and uses erected after the effective date of these land development regulations shall be provided with adequate off-street parking facilities (including in certain specified cases, off-street parking facilities for the handicapped) for the use of occupants, employees, visitors, customers, or patrons. It is also the intent of these land development regulations that the public interest, welfare, and safety require that certain uses provide adequate off-street loading facilities. Such off-street parking and off-street loading facilities shall be maintained and continued so long as the main use continues. (For definitions of "loading space, off-street," "parking space, handicapped," and "parking space, off-street," see Definitions, section 2.1.) 
4.2.17.1   Off-street parking and off-street loading: general.   
1.   Off-street parking and loading facilities shall be provided as set out in these land development regulations. Conforming buildings and uses existing as of the effective date of these land development regulations may be modernized, altered, or repaired without providing additional off-street parking or off-street loading facilities, providing there is no increase in floor area or capacity.
2.   Where a conforming building or use existed as of the effective date of these land development regulations and such building or use is enlarged in floor area, volume, capacity, or space occupied, off-street parking and off-street loading as specified in these land development regulations shall be provided for the additional floor area, volume, capacity, or space so created or used.
3.   Change in use of a building or use existing as of the effective date of these land development regulations shall require additional off-street parking and/or off-street loading facilities to the extent that the use shall provide additional parking spaces and/or off-street loading facilities amounting to the difference between the required number of parking spaces and/or off-street loading facilities for the new use and the required number of parking spaces for the previous use.
4.   The design, construction, and arrangement regulations herein set out for off-street parking and off-street loading facilities do not apply to one and two family (duplex) dwellings.
5.   Required off-street parking areas shall not be used for sales or display, dead storage, repair, dismantling, or servicing of any type or kind, nor shall areas devoted to such activities count as meeting off-street parking requirements.
6.   Unless otherwise specified and subject to meeting required landscaped buffer requirements, all required yards may be used for off-street parking.
4.2.17.2   Off-street parking and off-street loading facilities: identification, surfacing, drainage, lighting, access.  The required off-street parking and off-street loading facilities shall be: 
1.   Identified as to purpose and location when not clearly evident.
2.   Surfaced with one inch of type II asphaltic concrete surface course or the equivalent as approved as meeting standards established within article 5 of these land development regulations and maintained in a smooth, well-graded condition. Driveways, access aisles, and parking spaces for public and private schools offering academic courses, may be surfaced with grass or lawn. In addition, all special exceptions, as well as, churches and other houses of worship located in Conservation, Environmentally Sensitive and Agricultural zoning districts may be surfaced with grass or lawn.
3.   Drained so as not to cause any nuisance on adjacent property.
4.   So lighted as to prevent glare or excessive light on adjacent property.
5.   Arranged for convenient access and safety of pedestrians and vehicles.
6.   Designed to conform to curb break requirements (See Section 4.2.3).
7.   So arranged that no vehicle shall be required to back from such facilities directly onto public streets.
8.   Designed to provide curbs or motor vehicle stops or similar devices so as to prevent vehicles from overhanging on or into public right-of-way or adjacent property.
9.   Required off-street parking areas for three or more automobiles shall be designed, maintained, and regulated so that no parking or maneuvering incidental to parking shall be on a public street or walk, and sot that an automobile may be parked and unparked without moving another automobile.
4.2.17.3   Off-street parking: location.  The required off-street parking facilities shall be located on the same lot or parcel of land they are intended to serve, provided, however, that the board of adjustment may allow the establishment of such off-street parking facilities within 300 feet of the premises they are intended to serve when (1) practical difficulties prevent the placing of the facilities on the same lot as the premises they are designed to serve; (2) the owner of the said parking area shall enter into a written agreement with the board of county commissioners with enforcement running to the board of county commissioners providing that the land comprising the parking area shall never be disposed of except in conjunction with the sale of the building which the parking area serves so long as the facilities are required; and (3) the owner agrees to bear the expense of recording the agreement and agrees that the agreement shall be voided by the board of county commissioners if other off-street facilities are provided in accord with these land development regulations. 
4.2.17.4   Off-street parking: dimensional standards.  Each off-street parking space, with the exception of handicapped parking spaces, shall be a minimum of nine feet by 18 feet in size. Minimum aisle width shall be as follows: 
TABLE INSET:

 
      Aisle Width   
Angle of Parking    One Way    Two Way

60    18 feet    24 feet   
90    22 feet    24 feet   
For purposes of rough computation, an off-street parking space and necessary access and maneuvering room may be estimated at 300 square feet. However, off-street parking requirements will be considered to be met only where actual spaces meeting the requirements above are provided and maintained, improved in the manner required by these land development regulations, and in accordance with all ordinances and regulations of the board of county commissioners.
4.2.17.5   Off-street parking: handicapped parking spaces.  Except as otherwise specified herein, required off-street parking areas shall have a number of level parking spaces, as set forth in the following table, identified by above-grade signs as being reserved for physically handicapped persons. Each parking space so reserved shall be not less than 13 feet in width and 20 feet in length.

Parking spaces for the physically handicapped shall be located as close as possible to elevators, ramps, walkways, and entrances. These parking spaces should be located so that physically handicapped persons are not compelled to wheel or walk behind parked cars to reach entrances, ramps, walkways, and elevators. (See section 4.2.2 for additional provisions regarding accessibility for physically handicapped persons.)
4.2.17.6   Off-street parking: plans required.  A plan shall be submitted with every application for a building permit for any building or use that is required to provide off-street parking. The plan shall accurately designate the required parking spaces, access aisles, and driveways, and the relation of the off-street parking facilities to the uses or structures such facilities are designed to serve. 
4.2.17.7   Off-street parking: combined off-street parking.  Two or more owners or operators of buildings or uses requiring off-street parking facilities may make collective provision for such facilities, provided that the total of such parking spaces when combined or used together shall not be less than the sum of the requirements computed separately. Any arrangement for combined off-street parking shall be subject to the filing of a legal instrument satisfactory to the attorney for the board of county commissioners insuring that such off-street parking will be maintained in the future so long as a use or uses requiring such off-street parking continue. 
No part of an off-street parking area required for any building or use shall be included as a part of an off-street parking area similarly required for another building or use unless the board of adjustment shall find that the type of use indicates that the period of usage will not overlap or be concurrent with each other.
4.2.17.8   Off-street parking: fractional measurements.  When units or measurements determining number of required off-street parking spaces result in requirement of a fractional space, then such fraction equal or greater than one-half shall require a full off-street parking space. 
4.2.17.9   Off-street parking: minimum requirement.  Irrespective of any other requirement of these land development regulations, each and every separate individual store, office, or other business shall be provided with at least one off-street parking space, unless specific provision to the contrary is made herein. 
4.2.17.10   Off-street parking: landscaping requirements.  Wherever in any zoning district off-street parking facilities are provided, such off-street parking facilities shall conform to the minimum landscaping requirements set forth in this section, except that one-family and two-family (duplex) residential dwellings and multi-level parking structures shall be exempt from such requirements. 
1.   Except as otherwise noted herein, a minimum of ten percent of any off-street parking area shall be landscaped with grass, plants, shrubs, and/or trees. Required landscaping may, in part, be located around the periphery of the off-street parking area; however, where possible a portion of the required landscaping shall also be located within the interior of the off-street parking area and shall be located in such a manner as to divide and break up the expanse of paving and guide traffic flow and direction.
2.   Each separate landscaped area shall contain a minimum of 50 square feet and shall have a minimum dimension of at least three feet, and shall include at least one tree, with the remaining area adequately landscaped with shrubs, ground cover, or other landscaping material.

Trees shall be a minimum of four feet overall height immediately after planting. Trees shall not be planted closer than six feet to any public street or other public works, unless the tree root system is completely contained within a barrier for which the minimum interior dimensions shall be five feet square and five feet deep, and for which the construction requirements shall be four-inch-thick concrete reinforced with #6 road mesh (6 6 6) or equivalent.
4.   Required landscaped areas shall be maintained by the property owner and continued so long as the main use continues. Failure to maintain required landscaped area shall be a violation of these land development regulations.
5.   See also section 4.2.3, Visibility at intersections and curb breaks.
4.2.17.11   Off-street loading: specifications, amounts.  Off-street loading facilities are required by these land development regulations so that vehicles engaged in unloading will not encroach on or interfere with public use of streets and alleys by pedestrians and so that goods, materials, or things for delivery and shipping. Off-street loading facilities supplied to meet the needs of one use may not be considered as meeting the needs of another use. Off-street parking facilities may not be used or counted as meeting off-street loading requirements. 
When the use of a structure or land or any part thereof is changed to a use requiring off-street loading facilities, the full amount of off-street loading space required shall be supplied and maintained. When any structure is enlarged or any use extended so that the size of the resulting occupancy requires off-street loading space, the full amount of such space shall be supplied and maintained for the structure or use in its enlarged or extended size.
Each off-street loading space shall be directly accessible from a street or alley without crossing or entering any other required off-street loading space. Such loading space shall be arranged for convenient and safe ingress and egress by motor truck and/or trailer combination.

4.2.17.13   Off-street loading: plans required.  A plan shall be submitted with every application for a building permit for any use or structure required to provide off-street loading facilities. The plan shall accurately designate the required off-street loading spaces, access thereto, dimensions, and clearance. 
4.2.17.14   Off-street loading: combined off-street loading.  Collective, joint, or combined provisions for off-street loading facilities for two or more buildings or uses may be made, provided that such off-street loading facilities are equal in size and capacity to the combined requirements of the several buildings or uses and are designed, located, and arranged to be usable thereby. 
Any arrangement for combined off-street loading shall be subject to the filing of a legal instrument satisfactory to the attorney for the board of county commissioners insuring that such off-street loading will be maintained in the future so long as a use or uses requiring such off-street loading continue.

4.2.22.1   Intent.  Signs may unreasonably distract the attention of motorists and interfere with traffic safety. Indiscriminate erection and maintenance of signs seriously detract from the enjoyment and pleasure in the natural scenic beauty of the areas subject to these land development regulations and, in turn, injuriously affects the economic well being of the citizenry. Thus, it is the intent of these regulations to prevent the uncontrolled erection of signs. The provisions of this section are intended to provide for the regulation of types, sizes, and locations of signs in relation to the identification of various uses and activities on premises, to provide for certain types and locations of off-site signs, and to supplement the regulations set out in the schedule of district regulations.

Where permanent structures are involved in providing essential services, such structures shall conform insofar as possible to the character of the district in which the property is located, as to architecture and landscaping characteristics of adjoining properties.
The following standards shall apply to all new or expanded communications towers, except as exempted in subsection 4. above.
(1)   Location.  Communications towers are allowed in all land use districts including "Residential" districts when the following requirements are met: 
(a)   Every reasonable effort shall be made to locate the telecommunications tower in a non-residential land use district, including, but not limited to where feasible based on engineering and economic considerations;
(b)   Where the applicant seeks to locate a communication tower in a residential district the applicant shall demonstrate the no other industrial commercially or agriculturally zoned property is available to the applicant for this intended use;
(c)   If the proposed location is within a residential district, the proposed location will reasonably minimize the impact of the communication tower due to the height, use or appearance of the adjacent structures or surrounding area;
(d)   There are no existing building structures located within the area that are reasonably available to the applicant for this intended purpose and serve the applicants propagation needs;
(e)   No other existing communication tower meeting the applicants needs is located within the area is reasonably available to the applicant for purposes of collocation. Further, owners of communications towers must provide access and space for government-owned antennae where possible on a basis not less favorable than is required for private collocation;
(f)   The proposed height of the communication tower is the minimum necessary by the applicant to satisfy the applicant's communications system needs at this location;
(g)   No communication tower shall be located in violation of Columbia County Ordinance No. 77-6 (Lake City Airport Hazard Zoning Ordinance) as amended;
(h)   No communication tower shall be located or allowed which causes the existing airport license of any airport as defined herein or as "airport" as defined in F.S. chapter 330, (1995), as amended, to be limited, modified, restricted or otherwise changes as result of the siting of such communication tower; and,
(i)   The applicant must provide a written, notarized statement to the Building Department of Columbia County demonstrating compliance with [subsections] (1)(a) through (h). Requests to locate communications towers in land use districts can only be approved by the zoning board of adjustment at a duly noticed public hearing.
(2)   Design and construction.  The following criteria shall apply to the design and construction of communications towers. 
(a)   All other applicable permits must be obtained, including Federal Communication Commission (FCC) and Columbia County building permit approvals before construction. All tower facilities shall comply or exceed current standards and regulations of the FAA, the FCC and any other agency of the federal or state government with the authority to regulate towers and antennas. If such standards and regulations are changed, then the owner(s) shall bring such tower or antennas into compliance with such revised standards and regulations to the extent required by such governmental agency;
(b)   All communication towers shall be designed and constructed to EIA/TIA 222-E Standards or greater (at the option of the applicant) as published by the Electronic Industries Association, as may be amended from time to time. Communication tower owners shall be responsible for periodic inspections of such towers at least every two years to ensure structural integrity. Such inspections shall be conducted by a structural engineer with a current license issued by the State of Florida. The results of the inspection shall be provided in writing to the Columbia County Building Department Director upon request;
(c)   All towers shall be designed and constructed so that in the event of collapse or failure the tower structure will fall completely within the parcel or property where the tower is located. However, the applicant may apply for a waiver of this restriction upon showing of need and adequate safety of surrounding property;
(d)   All communication tower supports and peripheral anchors shall be located within the parcel or property where the tower is located;
(e)   Communication towers shall be marked and lighted as required by FCC, or other state or federal agency of competent jurisdiction;
(f)   All accessory buildings or structures shall comply with other applicable provisions of the zoning regulations and land use code;
(g)   Setbacks for communication tower accessory buildings and structures will comply with those required for the zoning district in which the tower is located. The board of adjustment may reduce this setback by 50 percent to allow placement of an additional equipment building or permitted accessory structure to encourage collocation/shared use of tower structures. Setbacks will be measured as provided within these zoning regulations; and
(h)   Advertising shall be in compliance with the sign regulations contained within these zoning regulations;
(i)   The perimeter base of all communication towers must be enclosed within a security fence no less than eight feet in height with access secured by a locked gate; and

Such identification shall also include the telephone number of a contact person.
Communication towers or antenna existing on the effective date of these land development regulations that are damaged or destroyed may be rebuilt and all such towers or antennas may be modified or replaced; provided the type, height, and location of the tower on site shall be of the same type and intensity (or lesser height or intensity (e.g., a monopole in substitution for a lattice tower)) as the original facility approved. Building permits to rebuild any such tower shall otherwise comply with the applicable county building code requirements together with the design and construction criteria required by section 21.9(2), entitled Design and Construction, subparagraphs (a), (b), (c) and (e), and shall be obtained within one year from the date the tower is damaged or destroyed. If no permit is obtained or said permit expires, the communication tower shall be deemed abandoned as specified in this Section.
Any communication tower or antenna found not to be in compliance with code standards, or found to constitute a danger to persons or property, upon notice to the owner of the communications facility, such tower or antenna shall be brought into compliance or removal within 90 days. In the event the use of any communication tower has been discontinued for a period of one year, the tower shall be deemed to be abandoned. Determination of the date of abandonment shall be made by the planning and zoning administrator who shall have the right to request documentation and/or affidavits from the communication tower owner/operator regarding the issue of tower usage. Upon such abandonment, the owner/operator of the tower shall have an additional 90 days within which to:
(1)   Reactivate the use of the tower or transfer the tower to another owner/operator who makes actual use of the tower; or
(2)   Dismantle and remove the tower.
At the earlier of one year from the date of abandonment without reactivation or upon completion of dismantling and removal, any special exception and/or variance approval for the tower shall automatically expire.
The procedure in connection with the application and granting of special exceptions for essential services shall generally conform to that outlined in sections 23.3 and 23.5 of these zoning regulations; provided, however, that the criteria for the granting of a special exception for essential services shall be limited to a showing of the need for such services in the requested location, that it is in the public interest that such special exception be granted, and in compliance with the other provisions heretofore set out in this Section.
Meeting the requirement of this section shall not excuse the applicant from otherwise complying with the Columbia County Comprehensive Plan and these zoning regulations. The board of adjustment shall have the right and authority to waive certain requirements of this section where it is found that a literal application or enforcement of this section would result in practicable difficulty or unnecessary hardship and relief granted would not be contrary to the public interest or intent of this section, but will do substantial justice and remain in accordance with the spirit of this section. As a minimum, any request for such waiver shall meet the criteria for a variance as specified in section 23.6 of these zoning regulations.
In addition, an application for a special exception for any Telecommunications Tower facility or use of an alternative tower structure shall be made to the Zoning Administrator. Incomplete applications shall not be considered. A complete application shall contain the following:
(1)   Inventory of existing communication towers owned/operated by applicant in Columbia County. Each applicant for a tower site shall provide the county with an inventory of its existing communication towers that are either within the jurisdiction of Columbia County or within one-half mile of the border thereof, including specific location, height and design of each tower. The county staff may share such information with the applicants seeking to locate communication towers within Columbia County.
(2)   Description of the communication tower's area of service identifying the use of the tower or antenna for coverage or capacity.
(3)   If required, photo simulations of the proposed telecommunications facilities illustrating the potential visual impact.
(4)   Site plan or plans to sale specifying the location of tower(s), guy anchors (if any), accessory buildings or uses, access, parking, fences, landscaped areas, and adjacent land uses.
(5)   Show legal description of the parent tract and leased parcel (if applicable). The location of the proposed communication tower in digital format compatible with the county's geographic information system, if the county has such system or similar system in place at the time. Certification by a Florida licensed land surveyor of the mean sea level elevation and topography.
(6)   Utilities inventory indicating the locations of all water, sewer, drainage, and power lines impacting the proposed tower site.
(7)   Report from a professional structural engineer, licensed in the State of Florida documenting the following:
(a)   Tower height and design, including technical engineering, and other pertinent factors governing the proposed tower design. A cross-section of the tower structure shall be included.
(b)   Total anticipated capacity of the structure, including number and types of antennas which can be accommodated.
(c)   Failure characteristics of the tower and demonstration that the site and setbacks are of adequate size to contain possible debris.
