(A) Purpose and intent. It is the purpose and intent of this Code to balance the goals of the City of Charlevoix's Master Plan to maintain its small-town character with the need to provide for safe lighting practices and to minimize light pollution for the enjoyment of Charlevoix's citizens and visitors.
(1) The use of outdoor lighting is often necessary for adequate nighttime safety and utility, but common lighting practices can also interfere with other legitimate public concerns. Principles among these concerns are:
(a) The degradation of the nighttime visual environment by production of unsightly and dangerous glare;
(b) Lighting practices that interfere with the health and safety of Charlevoix's citizens and visitors;
(c) Unnecessary waste of energy and resources in the production of too much light or wasted light; and
(d) Interference in the use or enjoyment of property which is not intended to be illuminated at night, and the loss of the scenic view of the night sky due to increased urban sky-glow.
(2) The concerns of safety, utility and aesthetic appearance need not compete. Good modern lighting practices can provide adequate light for safety and utility without excessive glare or light pollution. In nearly all cases, careful attention to when, where and how much nighttime lighting is needed will lead to better lighting practices.
(3) The topography and atmospheric conditions in northern Michigan are uniquely suited for commercial and private astronomical observation in the area. Unnecessary or excessive uses of outdoor nighttime lighting have an adverse impact on astronomical observation even at relatively distant observatories.
(4) Accordingly, it is the intent of this Code to require lighting practices and systems which will minimize light pollution, glare, light trespass, and conserve energy while maintaining nighttime safety, utility, security and productivity.
(B) Outdoor lighting. This definition includes the following terms and definitions:
(1) CLASS 1 LIGHTING. All outdoor lighting used for, but not limited to, outdoor sales or eating areas, assembly or repair areas, advertising and other signs, recreational facilities and other similar applications where color rendition is important to preserve the effectiveness of the activity.
(2) CLASS 2 LIGHTING. All outdoor lighting used for, but not limited to, illumination for walkways, roadways, equipment yards, parking lots and outdoor security where general illumination for safety and/or security of the grounds is the primary concern.
(3) CLASS 3 LIGHTING. Any outdoor lighting used for decorative effects including, but not limited to, architectural illumination, flag and monument lighting, and illumination of trees, bushes, and similar things.
(4) DIRECT ILLUMINATION. Illumination resulting from light emitted directly from a lamp, luminary, or reflector and is not light diffused through translucent signs or reflected from other surfaces such as the ground or building faces.
(5) DISPLAY LOT OR AREA. Outdoor areas where active nighttime sales activity occurs and where accurate color perception of merchandise by customers is required. To qualify as a display lot, one of the following specific uses must occur: automobile sales, boat sales, tractor sales, building supply sales, gardening or nursery sales, and assembly lots. Uses not on this list may be approved as display lot uses by the Zoning Administrator.
(6) FOOT-CANDLE. One lumen per square foot. Unit of illuminance. It is the luminous flux per unit area in the Imperial system. One foot-candle equals approximately 0.1 (0.093) lux.
(7) FULLY SHIELDED LIGHT FIXTURE. A light fixture that is shielded in such a manner that light rays emitted by the fixture, either directly from the lamp or indirectly from the fixture, are projected below a horizontal plane running through the lowest point on the fixture where light is emitted (see Figure 153.172)
Figure 153.172 Example of Fully Shielded Light Fixtures
(8) GLARE. The sensation produced by a bright source within the visual field that is sufficiently brighter than the level to which the eyes are adapted to cause annoyance, discomfort, or loss in visual performance and visibility; blinding light. The magnitude of glare depends on such factors as the size, position, and brightness of the source, and on the brightness level to which the eyes are adapted.
(9) INSTALLED. A light fixture attached or fixed in place, whether or not connected to a power source, of any outdoor light fixture.
(10) LIGHT POLLUTION. Any adverse effect of man-made light.
(11) LIGHT TRESPASS. Light spill falling over property lines.
(12) LUMEN. A unit used to measure the actual amount of visible light which is produced by a lamp as specified by the manufacture r.
(13) LUMINARY. The complete lighting assembly, less the support assembly.
(14) MOTION SENSING SECURITY LIGHTING. Any fixture designed, and properly adjusted, to illuminate an area around a residence or other building by means of switching on a lamp when motion is detected inside the area or perimeter and switching the lamp off when the detected motion ceases.
(15) MULTI-CLASS LIGHTING. Any outdoor lighting used for more than one purpose, for example security and decoration, such that its use falls under the definition of two or more classes as defined for Class 1, 2 and 3 lighting.
(16) NET ACREAGE. The remaining ground area of a parcel after deleting all portions for proposed and existing public rights-of-way and undeveloped area.
(17) OUTDOOR LIGHT FIXTURE. An outdoor illuminating device, outdoor lighting or reflective surface, lamp or similar device, permanently installed or portable, used for illumination, decoration, or advertisement. Such devices shall include, but are not limited to, lights used for:
(a) Buildings and structures;
(c) Parking lot lighting;
(e) Architectural lighting;
(f) Signs (advertising or other);
(h) Product display area lighting;
(i) Building overhangs and open canopies; or
(18) OUTDOOR RECREATION FACILITY. An area designed for active recreation, whether publicly or privately owned, including, but not limited to, parks, baseball diamonds, soccer and football fields, golf courses, tennis courts, and swimming pools.
(19) PARTIALLY SHIELDED LIGHT FIXTURE. A fixture shielded in such a manner that no more than 10% of the light emitted directly from the lamp or indirectly from the fixture is projected at an angle above the horizontal, as determined by photometric test or certified by the manufacturer. Luminaries mounted under canopies or other structures such that the surrounding structure effectively shields the light in the same manner are also considered partially shielded for the purposes of this Code.
(20) SECURITY LIGHTING. Lighting designed to illuminate a property or grounds for the purpose of visual security.
(21) UNSHIELDED FIXTURE. Any fixture that allows light to be emitted above the horizontal directly from the lamp or indirectly from the fixture or a reflector.
(22) WATT. The unit used to measure the electrical power consumption (not the light output) of a lamp.
(1) New uses, buildings and major additions or modifications. If the total cumulative increase in floor area is greater than 33% for single-family residential or greater than 25% for all other uses, then all outdoor lighting fixtures shall meet the requirements of this Code for the entire site, including previously installed and any new outdoor lighting. Cumulative modification or replacement of outdoor lighting constituting 25% or more of the permitted lumens for the parcel, no matter the actual amount of lighting already on a nonconforming site, shall constitute a major addition for purposes of this section.
(2) Minor additions. If the total cumulative increase in the floor area is 33% or less for single family residential or 25% or less for all other uses, then full conformance of the existing portion of the building or structure is not required. However, such projects shall require the submission of a complete inventory and site plan detailing all existing and any proposed new outdoor lighting.
(3) New lighting. Any new lighting on the site shall meet the requirements of this Code with regard to shielding and lamp type; the total outdoor light output after the modifications are complete shall not exceed that on the site before the modification, or that permitted by this Code, whichever is larger.
(4) Resumption of use after abandonment. If a property or use with nonconforming lighting is abandoned as defined in § 153.293, Nonconforming Buildings or Structures, then all outdoor lighting shall be reviewed and brought into compliance with this Code before the use is resumed.
(5) Public roadways. In general, this Code does not apply to city and state rights-of-way. However, the goal of the city is to have all such street lights fully shielded.
(D) Outdoor lighting standards.
(1) Light Emitting Diode Lighting (LED). Due to their high energy efficiency, long life and spectral characteristics, (LED) lamps are the preferred illumination source throughout the city. Their use is to be encouraged, when not required, for outdoor illumination whenever its use would not be detrimental to the use of the property.
(a) Class 1 Lighting. Light emitting diode (LED) lamps are not required. Businesses who choose to use LED as their primary lamps are eligible to apply for an additional 10% increase in the lumens per acre allowed for their site.
(b) Class 2 Lighting. Light emitting diode (LED) lamps are required. Up to 10% of the total lumens per acre allowed may be white light.
(2) Light trespass standard.
(a) All light fixtures, including security lighting, shall be aimed and shielded so that the direct illumination shall be confined to the property boundaries of the source.
(b) Particular care is to be taken to ensure that the direct illumination does not fall onto or across any public or private street or road. Motion sensing light fixtures shall be fully shielded and properly adjusted, according to the manufacturer's instructions, to turn off when detected motion ceases.
(3) Lamp and shielding. All light fixtures are required to be fully shielded and shall be installed in such a manner that the shielding complies with the definition of fully shielded light fixtures for all uses, including single-family and multi-family residential uses, except as provided below.

(c) Such lighting shall not include any light trespass as determined by a Michigan registered engineer as conforming to all applicable restrictions of this Code.
(d) Lighting time limitations. Outdoor display lot lighting shall conform to the hours of operation as established under Class 1 lighting standards. Any lighting on after the time limitations shall be considered Class 2 lighting and shall conform to all restrictions of this Code applicable to this class.
(3) Service station canopies.
(a) Class 2. Lighting for service station canopies shall be considered Class 2 lighting.
(b) Shielding. All luminaries shall be flush with the lower surface of canopies and utilize flat glass or plastic covers.
(c) Total under-canopy output. The total light output used for illuminating service station canopies, defined as the sum of under-canopy initial bare-lamp outputs in lumens, shall not exceed 40 lumens per square foot of canopy. All lighting mounted under the canopy, except internally illuminated signs, shall be included in the total. Fifty percent (50%) of the total lumen output of all lamps mounted within or under a canopy shall be included in the lumen per acre cap.
(4) Other lighting on parcels with special uses. All site lighting not directly associated with the special uses as permitted shall conform to all lighting standards described in this Code.
(F) Plan submittal and evidence of compliance.
(1) Plan submittal. Whenever a person is required to obtain a permit for outdoor lighting or signage, a conditional use permit, subdivision approval or any development plan approved by the city, including all city projects, or whenever a person requests a rezoning, the applicant shall, as part of the application process, submit sufficient information to enable the Zoning Administrator to determine whether proposed lighting complies with this Code. All applications may be subject to review and action by the Planning and Zoning Commission at the discretion of the Zoning Administrator.
(2) Applications. All applications shall include the following:
(a) A site plan indicating the location of all lighting fixtures, both proposed and any already existing on the site.
(b) A description of each illuminating device, fixture, lamp, support and shield, both proposed and existing. The description shall include, but is not limited to, manufacturer's catalog cuts and illustrations (including sections where required); lamp types, wattages and initial lumen outputs.
