A. Photometric Plan Required: A photometric plan shall be required for all land development applications where outdoor lighting is required or proposed, except for single-family residential developments where all streets are in public rights of way. The plan must show the location, mounting height, orientation, manufacturer, model number, photograph or catalog cut, light output in initial lumens, shielding or glare reduction devices, lamp type, and control devices for all outdoor lighting including wall mounted lighting. The plan must show the levels of illumination in foot-candles (fc) at ground level over the entire impacted area of the subject property and to all property lines.
B. Shielding Requirement: Any luminaire used for outdoor lighting shall have a fully shielded fixture, except for those fixtures used for sports field lighting.
C. Light Source Requirement: On property abutting a residential use, no direct light source (bulb) shall be visible at the property line at ground level. Notwithstanding the foregoing, the above regulation shall not be applicable to the light source from public streetlights, common area street lighting abutting individual lots, units or buildings within that residential development, or sports field lighting.
D. High Pressure Sodium Requirement: Any luminaire used for outdoor lighting shall use high pressure sodium, except for those luminaires used for sports field lighting and other lighting required by county, state or federal law. High pressure sodium luminaires may be substituted with an alternative luminaire not exceeding four thousand Kelvin (4,000°K) for new or replacement lighting installations. New and replacement lighting sources are subject to the requirements provided in this chapter.
E. Illumination Requirements: All outdoor lighting shall be subject to the minimum security code in title 8 of this code. Except as otherwise provided elsewhere in this section for sports fields, for all nonresidential uses and residential uses in developments with common area lighting, exposed sources of light shall be controlled so that direct and indirect illumination from any source shall not exceed one- tenth (0.1) foot-candle at lot lines abutting residential uses or one foot-candle at lot lines abutting nonresidential uses. In residential developments with common area lighting, the lot line foot-candle requirements shall apply only to the perimeter of the development and shall not apply to individual lots, units or buildings within the development.
F. Entrance/Exit: The maximum allowable light level measured at the point of intersection of an entrance drive of a nonresidential use with an adjacent street shall not exceed four (4) footcandles.
G. Sports Fields: Lighting levels for sports fields in conjunction with parks, recreational areas and recreational establishments shall comply with the following provisions:
1. Sports field lighting may be lit only during the hours between dusk and eleven o'clock (11:00) P.M.
2. When the sports field lights are on, light levels shall not exceed a maximum of nine (9) footcandles measured at the lot line abutting both residential and nonresidential districts and an average of three (3) foot-candles over that portion of the lot line that is illuminated by the sports field lights abutting both residential and nonresidential districts.
3. When the sports field lights are not on, regardless of the time of day, and for those portions of the property line not illuminated by the sports field lights, the light levels shall not exceed two-tenths (0.2) foot-candle at lot lines abutting residential uses and one footcandle at lot lines abutting nonresidential uses.
H. Under Canopy Lighting: All under canopy lighting must be recessed to reduce glare on surrounding properties. The lighting level under canopies shall not exceed a maximum of fifty (50) foot-candles.
Example of fully shielded fixture
I. Exempt Outdoor Lighting: The following outdoor lighting applications are exempt from all requirements of this chapter:

3. Public streetlights on public rights of way as required by title 10 of this code;
4. Temporary lighting used for holiday decoration;
5. Decorative yard, landscaping, and security lighting in residential districts when the light output does not exceed one thousand one hundred (1,100) lumens.
J. Nonconforming Lighting: All lighting fixtures subject to this title shall be brought into conformity at such time as a fixture is replaced, changed or added, with the exception of routine maintenance and bulb replacement of equal light output. (Ord. 2024-6, 3-7-2024)
