(b)
Airport overlay zones. The county has adopted airport overlay zones in chapter 103. The airport overlay zones limit uses and height of structures within the overlay zones. The provisions of the airport ordinance shall be in addition to the provisions of this chapter. Where requirements in the airport ordinance impose greater restrictions than this chapter, the provisions of the airport ordinance shall apply.
(c)
Double-counting prohibited. No part of a yard or other open space, or off-street parking or loading space required in connection with any structure for the purpose of complying with this chapter, shall be included as a part of a yard, open space, or off-street parking or loading space similarly required for any other structure.
(d)
Minimum lot size variances prohibited. No yard or lot existing on the effective date of this chapter shall be reduced in dimension or area below the minimum requirements set forth herein. Yards or lots created after the effective date of this chapter shall meet at least the minimum requirements established by this chapter.
(e)
Minimum road frontage required. No newly created lot shall contain any building used in whole or in part for residential purposes unless such lot abuts for at least 66 feet on at least one street, road or private lane, except 50 feet minimum may be allowed where no further division or parcels or lots can be created, or if fronting on a private lane. Where a lot that meets qualifications of a legal lot of record as of the effective date of the ordinance from which this chapter is derived does not abut a street, road, or private lane, access may be provided to a public road by an exclusive, unobstructed private easement of access with a minimum width of 20 feet.
(f)
Measurement of distances. Unless otherwise stated, distances shall be measured as follows:
(1)
Fire service. Distance for fire service shall be measured from the approximate center of the fire station as the center of the maximum fire service radius.
(2)
Road access. Distance for purposes of road access shall be measured from the nearest boundary of the development tract to the nearest hard surfaced or paved road, as measured along the approximate road centerlines.
(3)
LESA, nearby development. Distance for purposes of assessing the percentages of like-development and lot size within a specified radius, shall be measured from the perimeter of the parent parcel proposed for development.
(4)
Other. All other distances shall be measured between nearest property lines.
(g)
RLUIPA. This chapter is written with the intent that no land use regulation or requirement of this chapter shall be enforced in a manner that violates the federal Religious Land Use and Institutionalized Persons Act (RLUIPA) of 2000, or subsequent amendments or reauthorizations.
(h)
Agricultural land use notification. No zoning verification permit, site plan review approval for a new single-family dwelling, nor subdivision approval in the agricultural areas of the rural land use map, or within the AG Agricultural Zoning District shall be issued until the landowner, or the landowner's agent, signs an agricultural land use notification on a form provided by the zoning administrator. This requirement shall also apply to land proposed to be rezoned from the agricultural district to another district as part of a development application. The landowner shall insure that such notification shall be attached to the deed and shall become a separate entry on the abstract of title for all the property that is the subject of the permit or development. If the notification is issued in conjunction with a building permit for a new dwelling, the zoning site plan review will not be released until the notification form has been recorded. Agricultural land use notification forms shall inform the landowner that:
(1)
The land that is the subject of the permit or development is located in an agricultural area where the county has determined that agricultural uses are primary uses.
(2)
Agricultural practices may be accompanied by noise, dust, odor, light, smoke, and other off-site impacts at any time of day and year.
(3)
Agricultural practices may include new or expanded feedlots that conform to all state or federal standards, operation of machinery, storage and disposal of manure, and application by spraying or otherwise of chemical fertilizers, soil amendments, herbicides and pesticides.
(4)
Agricultural uses are given preference over other uses in agricultural areas.
(5)
If you live near an agricultural area, you should be prepared to accept inconveniences or discomfort associated with agricultural practices as a normal and necessary aspect of living in an agricultural area.
(6)
If a parcel of land subject to the agricultural land use notification provisions is subsequently annexed into a municipality, the notification shall become null and void.
(i)
Planned unit development overlay district: conflict with other regulations. An approved planned unit development, and associated governing plan prevails over any conflicting regulations in this section.

(d)
Buffers for commercial and industrial uses. The use of buffers is considered a necessary requirement to allow for the transition from commercial and industrial zoning districts and land uses to non-commercial or non-industrial zoning districts and land uses. The following provisions apply to buffers for commercial and industrial uses and structures.
(1)
When required. A buffer shall be provided when commercial or industrial land uses abut non-commercial or non-industrial land uses or zoning districts.
(2)
Buffer width. The buffer shall be a minimum of 50 feet. The buffer width may be reduced up to ten percent through an administrative exception approved by the zoning administrator. An administrative exception may be granted when, because of an exceptional situation, topographical condition, surroundings, size, shape or other condition of the property, the strict application of the buffer width provision would result in peculiar and exceptional practical difficulties or particular hardship upon the owner of such property.
(3)
Buffer composition and landscaping. All buffer areas shall be landscaped or fenced so as to provide a complete visual screen, and shall not include any structures other than allowed fencing, parking areas, storage areas, playgrounds, or other similar facilities.
a.
Fencing. Fencing may be used to meet the buffer requirement but shall not exceed 50 percent of the total buffer distance required. In addition, fencing used for buffering shall meet the general requirements for fencing in section 107-94(d).
b.
Landscaping. Landscaping shall use native plant and tree species. A combination of plant and tree species shall be used to create a vegetative overstory and understory. Tree species shall have a minimum mature height of 25 feet, and shall have a height of at least six feet within three years of installation.
c.
Screening. Visual screening shall be measured under leaf-on conditions and shall be measured from the elevation of the shared property line.
d.
Stormwater management. Buffer areas may include drainage swales, stormwater retention or infiltration areas, or other stormwater management areas only if landscaping and visual screening requirements can also be met.
e.
Berms. Berms may only be used if native plant and tree landscaping requirements can also be met. Berms must be vegetated to minimize erosion and to slow stormwater runoff.
(4)
Maintenance. All buffer areas shall be kept free of litter, debris, noxious weeds, and species of plants identified by the state DNR as exotic or invasive. Landscaping vegetation in buffer areas shall meet the screening requirements of subsection (d)(3) of this section on a continual basis for as long as the commercial or industrial use and structure continues.
(e)
Off-street parking and loading. Off-street parking and loading areas shall be required according to the following provisions.
(1)
Off-street loading areas, commercial and industrial uses. The following off-street loading areas shall be provided and maintained in any district in which there is a building that is to be occupied in whole or in part by an allowed commercial or industrial use:
a.
For a building having a gross floor area of 10,000 square feet or less there shall be at least one off-street loading berth; and
b.
One additional loading berth shall be provided for each additional 20,000 square feet or fraction thereof of gross floor area.
(2)

(3)
Off-street parking areas required. In all districts, off-street parking shall be required based on the principal use of the lot. Where there is a combination of uses on the lot or, where a principal use includes a combination of clearly distinct functions, the required number of parking spaces may be the sum calculated for each use or district function.
(4)
Administrative exception for off-street parking area. The required off-street parking area may be reduced through an administrative exception approved by the zoning administrator. An administrative exception reducing the number of required off-street parking spaces may be granted if the applicant submits a parking needs analysis which demonstrates that a sufficient level of off-street parking for the proposed use will be provided.
Table 107-93 Off-street parking requirements by use group or use category
(5)
Off-street parking area design standards. Required off-street parking areas shall meet the following design standards:

Where a lot does not abut a public or private alley or easement of access there shall be provided an access drive not less than nine feet in width in the case of a dwelling, and not less than 18 feet in width in all other cases leading to the loading and unloading space and parking or storage areas required hereunder in such manner as to secure the most appropriate development of the property in question; except where provided in connection with a use permitted in a residence district, such easement of access or access drive shall not be located in any residential district.
e.
Surfacing, grading, drainage.
1.
In the urban service area, all commercial drives and parking areas are to be paved with an asphaltic or Portland cement binder pavement, or such other hard but permeable surfaces.
2.
In all other land use areas, dust-controlled gravel parking areas shall be permitted. In those instances where the access is onto a hard surfaced road, the driveway shall be hard surfaced at a minimum to the property line. In all cases where handicapped parking is required, the handicapped space shall be paved, along with the most direct route to public areas. Parking areas and drives shall be so graded and drained as to dispose of or infiltrate all surface water accumulation within the area; and shall be so arranged as to provide for orderly and safe loading or unloading and parking and storage of motor vehicles.

(3)
Associated with an allowed temporary use. Any temporary structure associated with a temporary use allowed under section 107-93(c), need not comply with district yard requirements but shall be set back from all lot lines and otherwise be located on the property as may be required by the county to reduce any potential safety hazards to vehicles and pedestrian traffic on adjacent public ways, and to also reduce any adverse effects on adjacent properties. No permanent structures shall be erected except in conformance with the regulations of the zoning district within which the property is located.
(h)
General standards for setbacks and building lines. All structures shall meet the following requirements for yard setbacks and building lines:
(1)
Building lines on approved plats. Whenever an approved and recorded plat of subdivision shows a building line along any frontage for the purposes of creating a front yard or side street yard line, the building line thus shown shall apply along such frontage in place of any other yard line required in this chapter unless specific yard requirements in this chapter require a greater setback.
(2)
Corner vision clearance. On a corner lot except as provided for elsewhere in this chapter, nothing shall be erected, placed, planted or allowed to grow in such a manner as to impede vision between a height of 2½ feet and ten feet above the centerline grades of the area described as follows: that triangular shaped area bounded by the street, road, railroad, or other public right-of-way lines of a corner lot or tract and a straight line joining points on said right-of-way lines that are 30 feet from the point of intersection of said right-of-way lines.
(3)
Front yard requirements. In any district there shall be a minimum front yard required as stated in the yard requirements for that particular district. The minimum front yard depth as specified in any district shall be measured from the established or proposed right-of-way line of the street on which the lot fronts.
(4)
Front yards on double frontage lots. In any district where a double frontage lot runs through from street to street and where a front yard is required, such front yard shall be provided along each street lot line. Allowed accessory structures, such as a garage may be located in one front yard, and the front yard chosen shall be the front yard where similar structures are located on a majority of the lots on the block, or if there is no majority trend, then on the yard fronting the street of lower classification, provided the setback requirements in subsection (c) of this section are met.
(5)
Front yards on corner lots. The front yard setback for all corner lots shall apply to one street side of the lot. The owner of the lot may determine the front lot line for setback requirements at the time of an application for a zoning permit. Once the front line is established the rear lot line shall then be opposite and most distant from the front lot line. If principal and accessory structures are established, and the front is uncertain, the zoning administrator will determine the front yard by one of the following: the location of accessory structures, access, configuration of the principal structure on the lot, original platting, intent, or other relevant site specific conditions.
(6)
Rear yards on triangular shaped lots. Rear setbacks on triangular shaped lots shall be determined by using the rear setback distance for the zoning district drawn along each leg of the triangle and then connected by a straight line.
(7)
Exceptions to yard setback requirements. A required yard setback shall be kept open except for the following:
a.
Fences or freestanding walls.
b.
Ordinary projections from buildings not to exceed 24 inches including roof overhang.
c.
For commercial and industrial buildings, up to 20 percent of the required front yard area may be covered by arcades, canopies, roofs, solar power systems, or similar architectural features.
(i)
Separation distance requirements for structures from feedlots. At the time of application, any proposed development shall be separated from any state department of natural resources (IDNR) permitted animal feeding operation by the distance required for the type of structure as provided for in appendix C of this chapter.
(j)
Sign regulations. The purpose of this section is to establish minimum requirements to regulate the location, use and bulk of signs within the various zoning districts provided for in this chapter. All signs in any district shall be located, erected and maintained in compliance with the following regulations, in addition to other local, state or federal regulations:
(1)
Sign area. Sign area shall include the combination of the writing, copy, message, emblem, illustrations or other display, together with any background material or color forming an integral part of the display, but not including the supporting framework. A sign face's surface area is typically computed by measuring the square footage of all the space enclosed within the extreme edges of a sign's face(s).
a.
Multiple-faced signs. One face of a multiple-faced sign is used in the calculation of the allowed cumulative sign area. If connecting sign faces are separated by more than 45 degrees, both sign faces shall count towards the cumulative sign area.
Example 1: Two separate signs on the same pole.
Example 2: The signs are separated by more than 45 degrees, so both sign 1 and sign 2 count towards maximum cumulative signage.
Example 3: Sign faces are separated by less than 45 degrees, therefor only sign 1, face 1 counts towards the maximum cumulative signage.
b.
Cumulative sign area. Cumulative sign area is the sum of the sign area of all signs on a parcel.
(2)
Height. Height shall be measured as the vertical distance from average ground level, exclusive of any filling, berming, mounding, or excavating solely for the purpose of locating the sign, to the highest point of the sign or support structure, whichever is tallest. If the average grade is more than two feet lower than the average grade of the nearest abutting street (if two streets are equidistant, the higher of the two), then the height of the detached sign shall be measured from the elevation of the street to the top of the higher of the sign face or sign structure.
(3)
Sign location. No part of a sign, including the furthest edge of a sign, shall encroach upon or extend beyond any lot line or required setback.
(4)
Zoning approval required. All new accessory and advertising signage requires a zoning site plan approval.
(5)
Exempt signs. The following signs are exempt from the regulations of this section:
a.
Miscellaneous traffic or other signs of a public agency, such as railroad crossing signs, and signs warning of danger, hazards, or unsafe conditions.
b.
Any sign which is located within a building but not visible from outside.
c.
Signs and notices required to be displayed, maintained, or posted by law or by any court or governmental order, rule, or regulation.
d.
Incidental signs, including no spraying, no hunting, seed variety, warning signs, and no trespassing signs.
(6)
Prohibited signs.
a.
In rights-of-way. Signs shall not be allowed on any road, street, or highway right-of-way except for official traffic, street, or related signs and structures approved for placement by the public agency controlling the right-of-way.
b.
Traffic hazard. No sign or sign structure shall be erected at any location where it may, by reason of its size, shape, design, location, content, coloring, or manner of illumination, constitute a traffic hazard or a detriment to traffic safety by obstructing the vision of drivers, by obscuring or otherwise physically interfering with any official traffic control device, or which may be confused with an official control device.
(7)
Signs within intersection sight triangles. Signs must be located in accordance with the corner vision clearance provisions of section 107-94(h)(2) and shall be so erected and maintained that an unobscured visual sight area is provided. Such unobscured area, at a minimum, shall extend from a distance of two feet above finished street grade to ten feet above said grade. No more than two pole or post supports no greater than ten inches in diameter shall be permitted within such unobscured area.
(8)
Home occupations. Lots where a conditional use home occupation has been approved by the board of adjustment are allowed one additional sign for the onsite home occupation use in accordance with the regulations in section 107-113(h).
(9)
Nonconforming signs. No nonconforming sign shall be altered or reconstructed, unless the alteration or reconstruction is in compliance with the provisions of this subsection (j). For the purpose of this subsection only, the term "altered or reconstructed" shall not include minor maintenance, minor repair, landscaping around the sign, or the replacement of bulbs, changeable letters or figures, or other embellishments if such changes do not increase the size of the sign or the degree of its nonconformance.
(10)

(g)
RLUIPA. This chapter is written with the intent that no land use regulation or requirement of this chapter shall be enforced in a manner that violates the federal Religious Land Use and Institutionalized Persons Act (RLUIPA) of 2000, or subsequent amendments or reauthorizations.
(h)
Agricultural land use notification. No zoning verification permit, site plan review approval for a new single-family dwelling, nor subdivision approval in the agricultural areas of the rural land use map, or within the AG Agricultural Zoning District shall be issued until the landowner, or the landowner's agent, signs an agricultural land use notification on a form provided by the zoning administrator. This requirement shall also apply to land proposed to be rezoned from the agricultural district to another district as part of a development application. The landowner shall insure that such notification shall be attached to the deed and shall become a separate entry on the abstract of title for all the property that is the subject of the permit or development. If the notification is issued in conjunction with a building permit for a new dwelling, the zoning site plan review will not be released until the notification form has been recorded. Agricultural land use notification forms shall inform the landowner that:
(1)
The land that is the subject of the permit or development is located in an agricultural area where the county has determined that agricultural uses are primary uses.
(2)
Agricultural practices may be accompanied by noise, dust, odor, light, smoke, and other off-site impacts at any time of day and year.

The following provisions apply to buffers for commercial and industrial uses and structures.
(1)
When required. A buffer shall be provided when commercial or industrial land uses abut non-commercial or non-industrial land uses or zoning districts.
(2)
Buffer width. The buffer shall be a minimum of 50 feet. The buffer width may be reduced up to ten percent through an administrative exception approved by the zoning administrator. An administrative exception may be granted when, because of an exceptional situation, topographical condition, surroundings, size, shape or other condition of the property, the strict application of the buffer width provision would result in peculiar and exceptional practical difficulties or particular hardship upon the owner of such property.
(3)
Buffer composition and landscaping. All buffer areas shall be landscaped or fenced so as to provide a complete visual screen, and shall not include any structures other than allowed fencing, parking areas, storage areas, playgrounds, or other similar facilities.

b.
Landscaping. Landscaping shall use native plant and tree species. A combination of plant and tree species shall be used to create a vegetative overstory and understory. Tree species shall have a minimum mature height of 25 feet, and shall have a height of at least six feet within three years of installation.
c.
Screening. Visual screening shall be measured under leaf-on conditions and shall be measured from the elevation of the shared property line.
d.
Stormwater management. Buffer areas may include drainage swales, stormwater retention or infiltration areas, or other stormwater management areas only if landscaping and visual screening requirements can also be met.
e.
Berms. Berms may only be used if native plant and tree landscaping requirements can also be met. Berms must be vegetated to minimize erosion and to slow stormwater runoff.
(4)
Maintenance. All buffer areas shall be kept free of litter, debris, noxious weeds, and species of plants identified by the state DNR as exotic or invasive. Landscaping vegetation in buffer areas shall meet the screening requirements of subsection (d)(3) of this section on a continual basis for as long as the commercial or industrial use and structure continues.
(e)
Off-street parking and loading. Off-street parking and loading areas shall be required according to the following provisions.
(1)
Off-street loading areas, commercial and industrial uses. The following off-street loading areas shall be provided and maintained in any district in which there is a building that is to be occupied in whole or in part by an allowed commercial or industrial use:
a.
For a building having a gross floor area of 10,000 square feet or less there shall be at least one off-street loading berth; and
b.
One additional loading berth shall be provided for each additional 20,000 square feet or fraction thereof of gross floor area.

(3)
Off-street parking areas required. In all districts, off-street parking shall be required based on the principal use of the lot. Where there is a combination of uses on the lot or, where a principal use includes a combination of clearly distinct functions, the required number of parking spaces may be the sum calculated for each use or district function.
(4)
Administrative exception for off-street parking area. The required off-street parking area may be reduced through an administrative exception approved by the zoning administrator. An administrative exception reducing the number of required off-street parking spaces may be granted if the applicant submits a parking needs analysis which demonstrates that a sufficient level of off-street parking for the proposed use will be provided.
Table 107-93 Off-street parking requirements by use group or use category
(5)
Off-street parking area design standards. Required off-street parking areas shall meet the following design standards:

Where a lot does not abut a public or private alley or easement of access there shall be provided an access drive not less than nine feet in width in the case of a dwelling, and not less than 18 feet in width in all other cases leading to the loading and unloading space and parking or storage areas required hereunder in such manner as to secure the most appropriate development of the property in question; except where provided in connection with a use permitted in a residence district, such easement of access or access drive shall not be located in any residential district.
e.
Surfacing, grading, drainage.
1.
In the urban service area, all commercial drives and parking areas are to be paved with an asphaltic or Portland cement binder pavement, or such other hard but permeable surfaces.
2.
In all other land use areas, dust-controlled gravel parking areas shall be permitted. In those instances where the access is onto a hard surfaced road, the driveway shall be hard surfaced at a minimum to the property line. In all cases where handicapped parking is required, the handicapped space shall be paved, along with the most direct route to public areas. Parking areas and drives shall be so graded and drained as to dispose of or infiltrate all surface water accumulation within the area; and shall be so arranged as to provide for orderly and safe loading or unloading and parking and storage of motor vehicles.

(3)
Associated with an allowed temporary use. Any temporary structure associated with a temporary use allowed under section 107-93(c), need not comply with district yard requirements but shall be set back from all lot lines and otherwise be located on the property as may be required by the county to reduce any potential safety hazards to vehicles and pedestrian traffic on adjacent public ways, and to also reduce any adverse effects on adjacent properties. No permanent structures shall be erected except in conformance with the regulations of the zoning district within which the property is located.
(h)
General standards for setbacks and building lines. All structures shall meet the following requirements for yard setbacks and building lines:
(1)
Building lines on approved plats. Whenever an approved and recorded plat of subdivision shows a building line along any frontage for the purposes of creating a front yard or side street yard line, the building line thus shown shall apply along such frontage in place of any other yard line required in this chapter unless specific yard requirements in this chapter require a greater setback.
(2)
Corner vision clearance. On a corner lot except as provided for elsewhere in this chapter, nothing shall be erected, placed, planted or allowed to grow in such a manner as to impede vision between a height of 2½ feet and ten feet above the centerline grades of the area described as follows: that triangular shaped area bounded by the street, road, railroad, or other public right-of-way lines of a corner lot or tract and a straight line joining points on said right-of-way lines that are 30 feet from the point of intersection of said right-of-way lines.
(3)
Front yard requirements. In any district there shall be a minimum front yard required as stated in the yard requirements for that particular district. The minimum front yard depth as specified in any district shall be measured from the established or proposed right-of-way line of the street on which the lot fronts.
(4)
Front yards on double frontage lots. In any district where a double frontage lot runs through from street to street and where a front yard is required, such front yard shall be provided along each street lot line. Allowed accessory structures, such as a garage may be located in one front yard, and the front yard chosen shall be the front yard where similar structures are located on a majority of the lots on the block, or if there is no majority trend, then on the yard fronting the street of lower classification, provided the setback requirements in subsection (c) of this section are met.
(5)
Front yards on corner lots. The front yard setback for all corner lots shall apply to one street side of the lot. The owner of the lot may determine the front lot line for setback requirements at the time of an application for a zoning permit. Once the front line is established the rear lot line shall then be opposite and most distant from the front lot line. If principal and accessory structures are established, and the front is uncertain, the zoning administrator will determine the front yard by one of the following: the location of accessory structures, access, configuration of the principal structure on the lot, original platting, intent, or other relevant site specific conditions.
(6)
Rear yards on triangular shaped lots. Rear setbacks on triangular shaped lots shall be determined by using the rear setback distance for the zoning district drawn along each leg of the triangle and then connected by a straight line.
(7)
Exceptions to yard setback requirements. A required yard setback shall be kept open except for the following:
a.
Fences or freestanding walls.
b.
Ordinary projections from buildings not to exceed 24 inches including roof overhang.
c.
For commercial and industrial buildings, up to 20 percent of the required front yard area may be covered by arcades, canopies, roofs, solar power systems, or similar architectural features.
(i)
Separation distance requirements for structures from feedlots. At the time of application, any proposed development shall be separated from any state department of natural resources (IDNR) permitted animal feeding operation by the distance required for the type of structure as provided for in appendix C of this chapter.
(j)
Sign regulations. The purpose of this section is to establish minimum requirements to regulate the location, use and bulk of signs within the various zoning districts provided for in this chapter. All signs in any district shall be located, erected and maintained in compliance with the following regulations, in addition to other local, state or federal regulations:
(1)
Sign area. Sign area shall include the combination of the writing, copy, message, emblem, illustrations or other display, together with any background material or color forming an integral part of the display, but not including the supporting framework. A sign face's surface area is typically computed by measuring the square footage of all the space enclosed within the extreme edges of a sign's face(s).
a.
Multiple-faced signs. One face of a multiple-faced sign is used in the calculation of the allowed cumulative sign area. If connecting sign faces are separated by more than 45 degrees, both sign faces shall count towards the cumulative sign area.
Example 1: Two separate signs on the same pole.
Example 2: The signs are separated by more than 45 degrees, so both sign 1 and sign 2 count towards maximum cumulative signage.
Example 3: Sign faces are separated by less than 45 degrees, therefor only sign 1, face 1 counts towards the maximum cumulative signage.
b.
Cumulative sign area. Cumulative sign area is the sum of the sign area of all signs on a parcel.
(2)
Height. Height shall be measured as the vertical distance from average ground level, exclusive of any filling, berming, mounding, or excavating solely for the purpose of locating the sign, to the highest point of the sign or support structure, whichever is tallest. If the average grade is more than two feet lower than the average grade of the nearest abutting street (if two streets are equidistant, the higher of the two), then the height of the detached sign shall be measured from the elevation of the street to the top of the higher of the sign face or sign structure.
(3)
Sign location. No part of a sign, including the furthest edge of a sign, shall encroach upon or extend beyond any lot line or required setback.
(4)
Zoning approval required. All new accessory and advertising signage requires a zoning site plan approval.
(5)
Exempt signs. The following signs are exempt from the regulations of this section:
a.
Miscellaneous traffic or other signs of a public agency, such as railroad crossing signs, and signs warning of danger, hazards, or unsafe conditions.
b.
Any sign which is located within a building but not visible from outside.
c.
Signs and notices required to be displayed, maintained, or posted by law or by any court or governmental order, rule, or regulation.
d.
Incidental signs, including no spraying, no hunting, seed variety, warning signs, and no trespassing signs.
(6)
Prohibited signs.
a.
In rights-of-way. Signs shall not be allowed on any road, street, or highway right-of-way except for official traffic, street, or related signs and structures approved for placement by the public agency controlling the right-of-way.
b.
Traffic hazard. No sign or sign structure shall be erected at any location where it may, by reason of its size, shape, design, location, content, coloring, or manner of illumination, constitute a traffic hazard or a detriment to traffic safety by obstructing the vision of drivers, by obscuring or otherwise physically interfering with any official traffic control device, or which may be confused with an official control device.
(7)
Signs within intersection sight triangles. Signs must be located in accordance with the corner vision clearance provisions of section 107-94(h)(2) and shall be so erected and maintained that an unobscured visual sight area is provided. Such unobscured area, at a minimum, shall extend from a distance of two feet above finished street grade to ten feet above said grade. No more than two pole or post supports no greater than ten inches in diameter shall be permitted within such unobscured area.
(8)
Home occupations. Lots where a conditional use home occupation has been approved by the board of adjustment are allowed one additional sign for the onsite home occupation use in accordance with the regulations in section 107-113(h).
(9)
Nonconforming signs. No nonconforming sign shall be altered or reconstructed, unless the alteration or reconstruction is in compliance with the provisions of this subsection (j). For the purpose of this subsection only, the term "altered or reconstructed" shall not include minor maintenance, minor repair, landscaping around the sign, or the replacement of bulbs, changeable letters or figures, or other embellishments if such changes do not increase the size of the sign or the degree of its nonconformance.
(10)
