(a) 
Purpose.
Good outdoor lighting at night benefits everyone and enhances the City’s nighttime character. New lighting technologies have produced lights that are extremely powerful, and these types of lights may be improperly installed so that they create problems of excessive glare and light trespass that reduce residents’ privacy. Excessive glare can be annoying and may cause safety problems. There is a need for lighting regulations that recognizes the benefits of good outdoor lighting and provides clear guidelines for its installation so as to help maintain and complement the City’s character and which strives to provide linkage between the built and natural environment and acknowledges and sustains the unique nature of the City’s corporate-commercial, suburban and rural lifestyles. Appropriately regulated, and properly installed, outdoor lighting will contribute to the safety and welfare of the residents of the City.
(b) 
Objectives.
Outdoor lighting for nonresidential uses and multifamily uses has the following objectives:
(1) 
It is intended to reduce the problems created by improperly designed and installed outdoor lighting in those areas zoned for nonresidential uses and multifamily uses;
(2) 
It is intended to eliminate problems of glare and minimize light trespass by establishing regulations which limit the area that certain types of outdoor light fixtures can illuminate and by limiting the total allowable illumination of lots located in the City;
(3) 
All lighting installed in nonresidential uses and multifamily uses should be designed with the idea of being a good neighbor, thereby eliminating or reducing unnecessary direct light from shining onto abutting properties or streets;
(4) 
It is the declared purpose of this division that nonconforming luminaries be eliminated and be required to conform to the regulations of this division within a reasonable time.
(Ordinance 6051-12 adopted 5/17/12)
(a) 
New fixtures or additional lighting.
This division shall apply to all installations of new fixtures or additional lighting to any new or existing nonresidential or multifamily use or structure.
(b) 
Nonconforming Lighting.
Luminaries installed prior to the adoption of the Ordinance from which this division is derived shall immediately be re-aimed or shielded such that the fixture no longer creates a nuisance as defined in Article II SECTION 201.1. Shielding may be accomplished by louvers, baffles, visors, or shields placed on the luminaries, or any other method whereby the light therefrom does not constitute a nuisance as defined in ARTICLE II SECTION 201.1.
(c) 
Exemptions.
(1) 
Street lighting installed by a governmental agency for public benefit on public rights-of-way; and
(2) 
Public outdoor recreational sport fields and sport courts complex.

Any light or combination of lighting that creates an outdoor lighting nuisance as defined in Article II Section 201.1.
(i) 
Any lighting installed to illuminate an unimproved surface or private outdoor recreational activities that exceed requirements set forth in this Ordinance without an approved variance, as set forth in Article V DIVISION 4 Section 541.4.

(Ordinance 6051-12 adopted 5/17/12)
At all building entry points average projected footcandle readings as determined by the point method photometrics shall not exceed a measurement of five (5) footcandles.
(Ordinance 6051-12 adopted 5/17/12)

(a) 
A variance as to the height restriction may be permitted by the Zoning Board of Adjustment for the replacement of luminaries installed prior to the adoption of the Ordinance from which this division is derived if such luminaires are damaged, destroyed, or otherwise become inoperable.
(b) 
A variance is permissible for such replacement luminaries only in those situations where more than one luminaire existed prior to the adoption of the Ordinance from which this division is derived. The Zoning Board of Adjustment may grant a variance, upon application by the property owner or his designee, if the Zoning Board of Adjustment determines that the replacement of a damaged, destroyed, or otherwise inoperable luminaire with a luminaire conforming to the height requirement set forth in this division would:

(2) 
Be aesthetically inconsistent with the remaining luminaires[;] in determining whether a replacement luminaire would be aesthetically inconsistent, the Zoning Board of Adjustment may consider the following factors:
(A) 
The location of the replacement luminaire on the subject property;
(B) 
The type of construction material of the replacement luminaire;
(C) 
The location of the subject property; and

(d) 
The mounting height of landscape lighting shall not exceed twenty-five (25) feet.
