(A) Lighting standards: general.
(1) It is the intent of lighting standards to provide for illumination levels on individual lots which are adequate for the safe and efficient movement of individuals or vehicles to and from a lot and within a lot. Light intensity shall not be so great as to cause objectionable glare beyond any lot line.
(2) No use shall produce light or glare creating a nuisance or hazard perceptible from any point beyond the lot lines.
(3) A lighting plan for proposed development shall be filed as part of the development plan application, per § 194.126 of this chapter.
(4) New or replacement lighting fixtures. Lighting standards shall apply to the installation of new outdoor lighting fixtures or the replacement of existing outdoor fixtures. Replacement of a fixture shall mean a change of fixture type or change to the mounting height or location of the fixture. Routine lighting fixture maintenance, such as changing lamps or light bulbs, ballast, starter, photo control, housing, lenses and other similar components, shall not constitute replacement and shall be permitted provided such changes do not result in a higher lumen output.
(5) Wavelength. Light from fixtures shall be outputted at a wavelength at or above 500nm to limit blue light.
(6) Color temperature. Light from fixtures shall have a correlated color temperature at or above 3000 degrees kelvin and below 4000 degrees kelvin to aid in visibility at night and protect circadian rhythm of nocturnal environments.
(B) Lighting standards: Urban B-0 / B-1 / B-2 / B-3 / VBD / I-ORT /1-1 /1-2 /1-3 / R-V / SU / PUD / R-MF-1 / R-MF-2. All lighting in Business, Industrial, Special Use Districts, and Planned Unit Development Districts, as well as the R-MF-1 and RMF-2 Districts, and shall comply with the following regulations. PUD Planned Unit Development Districts shall comply with the following unless unique standards are identified in the adopted preliminary Planned Unit Development district or ordinance.
(1) Style.
(a) Lighting of all off-street parking areas, outside storage, or outdoor operations shall be a “shoebox” style lighting. Specific to B-l and VBD, bronze “shoebox” style lighting shall be used.
(b) All exterior lighting, including wall pack lighting, shall be of metal halide or LED.
(2) Uniformity.
(a) Light standards and fixtures on a lot, including free-standing light fixtures and those attached to buildings, security lights, and architectural lights, shall be of consistent design and materials.
(b) Parking lot lights shall be of uniform size, design and height.
(3) Cutoff. All free-standing lights shall be of either a “down lighting” style with the light element completely shielded on all sides and the top; or be equipped with a refractor so as to direct light downward onto the lot.
(4) Light trespass. Lighting shall not cause illumination beyond any lot line or onto any right-of-way, based upon the zoning district of the real estate on the opposite side of such lot line or right-of-way, in excess of:
(a) If adjoining business or industrial districts - one foot candle.
(b) If adjoining open land, residential or special use districts - one-half foot candle.
(5) Architectural or sign lighting. Lighting shall be so directed and shielded so that the light element is not visible from any point along an adjacent public right-of-way.
(6) Color temperature. VBD: Light from fixtures shall have a correlated color temperature at or above 3000 degrees Kelvin and at or below 3500 degrees Kelvin to aid in visibility at night and protect circadian rhythm of nocturnal environments.
(C) Lighting standards: MRO. All lighting in U.S. Highway 421 - Michigan Road Corridor Overlay District shall comply with the following regulations:
(1) Uniformity.
(a) Light standards and fixtures on a lot, including free-standing light fixtures and those attached to buildings, security lights, and architectural lights within the development area shall be of consistent and uniform design and materials.
(b) Parking lot streetlights shall also be of uniform height not to exceed 24 feet. Luminaries for such lights shall be in proportion to the pole diameter and height.
1. Poles up to 12 feet in height: Minimum diameter of six inches.
2. Poles between 12 and 24 feet in height: Minimum diameter of eight inches.
(2) Cutoff. All lights within gas station canopies and adjacent to residential areas shall be of a “down lighting” type with the light element completely shielded on all sides and top. The Plan Commission may approve decorative lighting should it be more appropriate to the overall site design.
(3) Light trespass. Lighting shall not cause illumination beyond any lot line or onto any right-of-way, based upon the zoning district of the real estate on the opposite side of such lot line or right-of-way, in excess of:
(a) If adjoining business or industrial districts - 0.3 foot candle.
(b) If adjoining open land, residential or special use districts - 0.1 foot candle.
(D) Lighting standards: rural.
(1) In any district, outdoor lighting, where provided, shall be shall be of a design and size that is harmonious with the design of the building, the type of land use, and the type of adjacent land uses.
(2) If external spot or flood lighting is used, the light source should be shielded and restrained in such a manner so as not to illuminate or intrude on surrounding properties.
(3) Excessive brightness, flashing lights, and brilliant colors are not permitted.
(4) Lighting provided to illuminate off-street parking areas shall be so arranged, shielded and directed upon the parking area in such a manner as to not reflect or cause glare into adjacent properties or interfere with street traffic.
