§ 5-91. Definitions.
Unless specifically defined herein, all words or phrases used in this article shall be ascribed the meaning which they have in common usage:
Artificial light or artificial lighting means the light emanating from a manmade point source of light (see Point source of light, below).
Beach means the zone of unconsolidated material that is contiguous with the waters of the Gulf of Mexico and extends landward from the mean low water line to the place where there is marked change in material or physiographic form, or to the line of permanent vegetation (usually the effective limit of storm waves).
Bug light means any bulb/lamp 480 lumens or less that is specifically designed so as not to attract insects to the light, which is ordinarily yellow in color. This does not include insect killing devices (bug zappers) that attract insects.
Candela means the basic, international unit for measuring luminous intensity.
Coastal construction control line means the line established pursuant to the provisions of Section 161.053, Florida Statutes.
County Code means the codification of the ordinances of Okaloosa County, Florida.
Cumulatively illuminated means illuminated by numerous artificial light sources that as a group illuminate any portion of the beach or dune system seaward of the crest of the primary dune.
Directly illuminated means illuminated by one or more point sources of light directly visible to an observer standing on the beach.
Disorientation means inability of hatchling or adult see turtles to orient properly to the ocean.
Dune means a natural or man-made mound or ridge of loose sediments, usually sand-sized sediments, lying landward of the beach.
Existing means in existence as of the effective date of the ordinance from which these provisions are derived.
Frontal dune means the first natural or human-made mound of sand which is located immediately landward of the beach.
Full cut-off fixture means a fixture with a flat, horizontally oriented lens and opaque sides that does not permit light distribution above a horizontal plane located at the bottom of the fixture.
Hatchling means any individual of a species of sea turtle, within or outside of a nest, which has recently hatched from an egg.
Indirectly illuminated means illuminated by one or more point sources of light not directly visible to an observer standing on the beach.
Lamp means the source of light within the luminaire.
LED means light emitting diodes.
Light fixture means the device that holds the point source of light.
Long wavelength means light with wavelengths greater than 580 nanometers.
Low-pressure sodium light means an electric discharge lamp containing sodium, neon, and argon, that when illuminated appears amber-yellow.
Lumen means a unit of light output or flux, equal to the amount of light flow from one candela through a unit solid angle.
Luminaire means a complete unit that artificially produces and distributes light. An artificial light source, including fixture, ballast, mounting, and lamp(s).
Nest means an area where sea turtle eggs have been naturally deposited or subsequently relocated by an authorized permittee of the Florida Fish and Wildlife Conservation Commission.
Nesting habitat means the beach, frontal dune, and those portions of the primary dune accessible to sea turtles.
Nesting season means the period from May 1 through October 31 of each year.
New construction means the installation or development of a structure on a property for which no building permits had been issued prior to the effective date of the ordinance from which this article is derived; this definition does not include renovations of or attached additions to buildings in existence as of the effective date of the ordinance from which this article is derived.
Point source of light means a manmade source emanating light, including, but not limited to incandescent, tungsten-iodine (quartz), mercury vapor, fluorescent, metal halide, neon, halogen, high pressure sodium, and low pressure sodium light sources, as well as natural gas lights, torches, camp and bonfires. When a lamp is contained within a translucent fixture, the entire fixture shall be considered the point source of light.
Pole lighting means a light fixture set on a base or pole which raises the source of light higher than 48 inches off the ground.
Primary dune means a significant dune which has sufficient vegetation, height, and alongshore continuity to offer protective value to upland properties. The primary dune may be separated from the frontal dune by an interdunal trough; however the primary dune may be considered the frontal dune if located immediately landward of the beach.
Public parking lot means a parking lot owned by Okaloosa County and available for by the public for general access purposes and not in conjunction with a specific private business or interest.
Sea turtle or marine turtle means any marine-dwelling reptile of the families Cheloniidae or Dermochelyidae found in Florida waters or using the beach as nesting habitat, including the species means Caretta caretta (loggerhead), Chelonia mydas (green), Dermochelys coriacea (leatherback), Eretmochelys imbricata (hawksbill), and Lepidochelys kempi (Kemp's ridley). For purpose of this rule, sea turtle is synonymous with marine turtle.
Sea turtle conservation zone means:
(1)
South of U.S. 98 (Miracle Strip Parkway) in unincorporated Okaloosa County east of its intersection with Santa Rosa Boulevard to the westernmost boundary of the Gulf Islands National Seashore/Unit; and
(2)
South of Santa Rosa Boulevard from its intersection with US 98 west to the easternmost boundary of the Gulf Islands National Seashore/Unit.
Shield means an opaque, non-reflective covering, canopy or other such device fitted over a light source that blocks the light source from being observed from the beach and prevents the light from illuminating the beach.
Skyglow means an increase in light levels in the sky above natural ambient levels.
Tinted glass means any tinted glass treated to achieve an industry-approved, inside-to-outside light transmittance value of 45 percent or less. Such transmittance is limited to the visible spectrum (400 to 700 nanometers) and is measured as the percentage of light that is transmitted through the glass.
Translucent fixture means a fixture consisting of a material (e.g., frosted glass) that transmits light but causes sufficient diffusion to prevent a distinct image of the lamp inside.
Up-lighting means Lighting fixtures that are directed upward, usually onto objects (flags, monuments, signs, buildings, landscape, etc.).
Wildlife lighting means artificial lighting that minimizes the potential for negative affects to the nocturnal behaviors of nesting and hatchling sea turtles and other wildlife the following criteria apply:
(1)
The light source is mounted as low to the ground or floor as possible through the use of fixtures such as, low-mounted wall fixtures, low bollards, and ground-level fixtures;
(2)
The lumens emitted by the light source are the minimal required for the intended application;
(3)
The light source is contained within a full cut-off or fully shielded fixture such that no light is broadcast above a horizontal plane and the point source of light and any reflective surfaces of the fixture are not directly visible from the beach;
(4)
Lamps emit only long-wavelength light (greater than 560 nanometers). These long-wavelength light sources include low pressure sodium vapor lamps 8,000 lumens or less, bug lamps and some color-filtered compact fluorescent lamps 480 lumens or less, amber and red LEDs (light emitting diodes), and true red neon;
(5)
Luminaires, light fixtures, lamps, and other light sources that have been certified as meeting the criteria of wildlife lighting can be found on the joint Florida Fish and Wildlife Conservation Commission and the U.S. Fish and Wildlife Service Wildlife Lighting Certification Program (LCP) website URL:

Window tinting means tinting or film that meets the standards for tinted glass.
