ARTICLE XII
Lighting
§ 245-133 Outdoor lighting installations.
A.
Purpose and intent. The purpose of this article to minimize "light trespass" or "obtrusive light," or more specifically to regulate and reduce the nuisance caused by unnecessary intensity of artificial illumination of property and buildings, to mitigate the impact on ecosystems, to promote the safety and welfare of the citizens by restricting glare producing sources of light and generally establish proper levels of lighting.
B.
Scope.
(1)
The regulations in this article shall apply to all luminaries installed, erected or maintained in all districts except on parcels that contain a single-family or two-family dwelling unit, provided that the glare regulations set forth in § 245-143A do apply on single-family or two-family parcels where a luminary is not a fully shielded or full cut-off fixture and one or more neighboring parcels are affected by glare. The regulations apply in common areas of developments containing more than one main use on a lot, including condominiums regardless of the number of units per building. Examples of common areas include, but are not limited to, pathways, clubhouses, shared driveways, parking lots, and play areas.
(2)
New uses, buildings, and additions. All new land uses, developments, buildings, structures, or building additions of 25% or more in terms of gross floor area, either with a single addition or cumulative additions, subsequent to the effective date of this article shall meet the requirements of this section for the entire property. This provision includes additions of any size that increase the number of parking spaces by 25%. For building additions less than 25%, the applicant shall meet the provisions of this section for all new outdoor lighting installed.
(3)
Change of use. Any change of use to an existing building or structure, except in the case of a single tenant in a multitenant building, shall meet the requirements of this section for the entire property to the greatest extent possible as determined by the Zoning Administrator.
(4)
These regulations do not apply to the public right-of-way and shall not conflict with Village streetlights. The regulations do not apply to lighting necessary for emergency equipment or work conducted in the interest of law enforcement, or for the safety, health, or welfare of the community.

Minimum footcandles on pavement3 | 0.2 fc | 0.5 fc |
Maximum footcandles on pavement | 4.0 fc | 7.5 fc |
Uniform ratio maximum/minimum4 | 20:1 | 15:1 |
Maximum footcandles at five feet above pavement5 | 0.1 fc | 0.25 fc |
NOTES: | |
fc = footcandle | |
1 | For typical conditions. During periods of nonuse, the illuminance of certain parking facilities should be turned off or reduced to conserve energy. If reduced lighting is to be used only for the purpose of property security, it is desirable that the minimum (low point) value not be less than 0.1 footcandle. Reductions should not be applied to facilities subject to intermittent night use, such as at apartments, hospitals and transportation terminals. |
2 | The Plan Commission may allow increases from basic to enhanced security lighting levels, when personal security is an issue, such as where the parking facility is used during all hours of the day and night, where special security needs exist, or where vandalism or crime are possible. The Plan Commission may consider specific site characteristics, level of vehicle and pedestrian conflict, special security needs, and history or likelihood of crimes in making its determination. |
3 | Measured on the parking surface, without any shadowing effect from parked vehicles or trees at points of measurement. |
4 | The highest horizontal illuminance point at grade, divided by the lowest horizontal illuminance point or area should not be greater than the values shown. |
5 | Measured at 1.5 meters (five feet) above parking surface at the point of the lowest horizontal illuminance, excluding facing outward along boundaries. |

B.
Lighting levels shall be adequate to facilitate the activities taking place in such locations.
C.
In order to minimize the extent of direct glare, light fixtures mounted on canopies shall be recessed so that the lens cover is recessed or flush with the bottom surface (ceiling) of the canopy or shielded by the fixture or the edge of the canopy so that light is restrained to 85° or less from vertical.
D.
As an alternative (or supplement) to recessed ceiling lights, indirect lighting may be used where light is beamed upward and then reflected down from the underside of the canopy. When this method is used, light fixtures must be shielded so that direct illumination is focused exclusively on the underside of the canopy.
E.
Lights shall not be mounted on the top or sides (fasciae) of the canopy. The sides (fasciae of the canopy) shall not be illuminated in a manner other than that prescribed under the section of these regulations regulating signs.
F.
Areas around service station pump islands shall be illuminated so that the minimum horizontal illuminance at grade level is at least 1.0 footcandle and no more than 5.0 footcandles. The uniformity ratio (average illumination to minimum illumination) shall be no greater than 4:1. At the discretion of the Plan Commission, increased lighting levels may be permitted for enhanced security purposes only.
§ 245-146 Lighting of outdoor performance, sport and recreation facilities and playfields.
A.
Lighting levels for outdoor performance areas, sport and recreation facilities, and playfields shall not exceed by more than 5% the Illuminating Engineering Society of North America (IESNA) published standards for the proposed activity.

C.
The main lighting shall be turned off as soon as possible following the end of the event. The main lighting shall not remain on longer than 30 minutes following the end of the event. Where feasible, a low-level lighting system shall be used to facilitate patrons leaving the facility, cleanup, nighttime maintenance and other closing activities. The low-level lighting system shall provide an average horizontal illumination level at grade of no more than 3.0 footcandles, with a uniformity ratio (average illumination to minimum illumination) not exceeding 4:1.
§ 245-147 Security lighting.
A.
Security lighting is defined as "lighting designed and used to discourage crime and undesirable activity."
B.
Security lighting should use the lowest possible illumination to effectively allow surveillance.
C.
The use of sensor technologies, timers or other means to activate lighting during times when it will be needed may be required by the Plan Commission to conserve energy, provide safety, and promote compatibility between different land uses.
D.
In order to direct light downward and minimize the amount of light spill into the dark night sky, all security lighting fixtures shall be full cutoff fixtures as defined by the Illuminating Engineering Society of North America (IESNA).
E.
Security lighting shall be shielded and aimed so that illumination is directed to the designated areas.
F.
Where security lighting is proposed, the table below shall govern the range of permissible light levels for the listed applications. Where a proposed security lighting application is not identified in the table below, the table shall be used a guide for establishing the range of permissible light levels.
Security Lighting Application on Ground | Average Horizontal Illumination Level |

Buildings | 0.5 to 2.0 fc1 |
Perimeter fence | 0.5 fc2 |
Entrances | 10 fc3 |
Gatehouses | 30 fc4 |
Pedestrian pathways and access routes | 4 to 6 fc |
NOTES: | |
fc = footcandle | |
1 | The greater the brightness of the surrounding area, the higher the illuminance required to balance the brightness |
2 | Illuminance on the ground |
3 | Illuminance on the ground in the inspection area |
4 | Illuminance on the work-plane in the gatehouse. This lighting must be dimmable to low levels at night so the guard can see outside the gatehouse. |
§ 245-148 Architectural accent lighting.
A.
Fixtures used to accent architectural features, materials, colors, style of buildings, or art shall be located, aimed and shielded so that light is directed only on those features. Such fixtures shall be aimed or shielded so as to minimize light spill into the dark night sky. The Plan Commission may allow exceptions to this provision if minimal light escapes into the dark night sky or onto adjacent properties.
B.
Lighting fixtures shall not generate excessive light levels, cause glare, or direct light beyond the facade onto neighboring property, streets or the night sky.
C.
The maximum illumination of any vertical surface or angular roof surface in dark surroundings shall not exceed three footcandles.
D.
The maximum illumination of any vertical surface or angular roof surface in light surroundings shall not exceed five footcandles.
