The purpose of this article is to establish standards for electrical lighting installed within the city in order to protect the public health, safety and welfare. More specifically, the standards in this article are intended to:

A.

Ensure that minimum lighting levels within off-street vehicular use areas and city streets are adequate for the safe operation of vehicles and other modes of travel for which certain streets may be designed.

B.

Contain illumination to areas for which such illumination is intended and minimize light.

C.

Promote the city's parklike setting, whereby lighting is generally subtle and compliments building architecture, architectural features, and landscaped areas.

(Ord. No. 2016-12, § 3, 12-7-2016)

The provisions of this article shall apply to all land uses, and all occupancy classifications under the building code, with the exception of lighting installed by public utilities in conformance with the Florida Public Service Commission Approved Utility Tariff for public street lights and public facilities, including, but not limited to, public parks and their associated lighted recreation areas, athletic areas, courts, and fields. New light poles and light fixtures and all modifications of existing light poles and light fixtures shall comply with the provisions of this article.

(Ord. No. 2016-12, § 3, 12-7-2016)

A.

For the purposes of this article, the following words and phrases shall have the meanings set forth below.

Color Rendering Index (CRI). A value from one (1) to one hundred (100) (with one hundred (100) being optimal) rating a light source's ability to render an object's true colors.

Electrical plan. A plan or drawing showing the electrical wiring of the luminaires, electrical load calculations, panel schedules, and other information in accordance with the Florida Building Code.

Footcandle. A unit of illuminance; a measurement of the amount of light falling onto a surface; One (1) footcandle is one (1) lumen per square foot (Lm/fc2).

Glare. The sensation in the eye produced by a more intense source of light that causes annoyance, discomfort, or loss of visibility.

Glare disability. Glare that produces discomfort and reduces visual performance.

Lamp (bulb). Generic term for a manmade source created to produce optical radiation (light); a light source.

LED. Light emitting diode.

Light trespass. Light that falls beyond the property it is intended to illuminate; also called "light spillage." For the purpose of compliance with this article, light trespass is measured at the property line.

Luminaire. Light fixture; a complete lighting assembly consisting of lamp(s), socket(s), ballast, reflectors, lenses, and a housing.

Luminaire classification system (LCS). Classification of outdoor luminaires based on angular light distribution; uses the backlight, uplight, and glare (BUG) ratings of a specific luminaire. This replaces "cutoff" and "full cutoff" definitions for new luminaires. (See Reference Code IES TM-15-11.)

Luminaire, cutoff. A luminaire with light output of less than two and one-half percent (2.5%) above ninety (90) degrees and less than ten (10) percent above eighty (80) degrees.

Luminaire, full cutoff. A luminaire with light output of zero (0) above ninety (90) degrees and less than ten (10) percent above eighty (80) degrees.

Nonresidential property. Any property other than residential property as defined herein.

Occupancy group. The classification as to use and occupancy of buildings and structures, and the spaces therein, under the building code.

Residential property. Any property that is located within a residential zoning district, or occupied by an assisted living facility or other group housing, or for which a development order or permit has been issued for such occupancy.

Trespass: see, "Light trespass."

B.

The following resources shall be used for the design and testing of parking facility lighting. The standards contained therein are hereby adopted by reference and shall apply unless standards contained within this article are more stringent, in which case the more restrictive standards shall apply.
