i (a)The point source of light or any reflective surface of the light fixture is not directly visible from the beack (b)Areas seaward of the frontal dune are not directly or indirectly illuminated;and (c)Areas seaward of the frontal dune are not cumulatively illuminated. (2)Exterior artificial light fixtures within direct line-of-sight ofihe beach are considered appropriately designed if (a) Completely shielded downlight only fixtures or recessed fixtures haying low wattage (i.e., SO watts or less) "bug"type bulbs and non-reflective interior surfaces are used:Other fixtures that have appropriate shields,louvers,or cut-off features may also be used if they are in compliance with paragraphs(1)(a),(b),and(c)above;and (b) All fixtures are mounted as low in elevation as possible through use of low--mounted wall fixtures, low bollards, and ground-level fixtures. (3)Floodlights, uplights or spotlights for decorative and accent purposes that are directly visible from the beach, or which indirectly or cumulatively illuminate the beach,shall not be used. (4)Exterior lights used expressly for safety or security purposes shall be limited to the minimum number and configuration required to achieve their functional role(s). The use of motion detector switches that keep lights off except when approached and that switch lights on for the minimum duration possible are preferred. (5)Only low intensity Iighbng shall be used in parking areas within line-of-sight of the beach.Such lighting shall be- (a)Set on a base which raises the source of light no higher than 48 inches off the ground;and (b)Positioned or shielded so that the light is cast downward and the source of light or any reflective surface of the light fixture is not visible from the beach and does not directly or indirectly illuminate the beach. (6) Parking areas and roadways, including any paved or unpaved areas upon which motorized vehicles will park or operate, shall be designed and located to prevent vehicular headlights from directly or indirectly illuminating the beach. (7) Vehicular lighting, parking area lighting, and roadway lighting shall be shielded from the beach through the use of ground-level barriers.Ground-level barriers must not interfere with marine turtle nesting or hatchling emergence,or cause short-or long-term damage to the beach/dune system. (8)Tinted glass shall be installed on all windows and glass doors of single or multi-story structures within line-of-sight of the beach. (9)Use of appropriately shielded low pressure sodium vapor lamps and fixtures shall be preferred for high-intensity lighting applications such as lighting parking areas and roadways,providing security,and similar applications_ (10)Temporary lighting of construction sites during the marine turtle nesting season shall be restricted to the minimal amount necessary and shall incorporate all of the standards of this section. Spe4fic Aruhority 161.63 FS.La►r Implemented 161.163 FS.History M",3-30-93,Formerly 16B-55.006. 62B-55.007 Model Standards For Existing Beachfront Lighting. In order to provide the highest level of protection for nesting marine turtles and their hatchlings,local governments should adopt all of the following standards for existing artificial beachfront lighting sources: (1)Existing artificial light fixtures shall be repositioned,modified,or removed so that: (a)The point source of light or any reflective surface of the light fixture is not directly visible from the beach; (b)Areas seaward of the frontal dune are not directly or indirectly illuminated;and (c)Areas seaward of the frontal dune are not cumulatively illuminated. (2)The following measures shall be taken to reduce or eliminate the negative effects of existing exterior artificial lighting: (a)Reposition fixtures so that the point source of light or any reflective surface of the light fixture is no longer visible from the beach; (b)Replace fixtures having an exposed light source with fixtures containing recessed light sources or shields; (c)Replace traditional light bulbs with yellow"bug"type bulbs not exceeding50 watts; (d)Replace non-directional fixtures with directional fixtures that point down and away from the beach; (e)Replace fixtures having transparent or translucent coverings with fixtures having opaque shields covering an arc of at least 180 degrees and extending an appropriate distance below the bottom edge of the fixture on the seaward side so that the I ight source or any reflective surface of the light fixture is not visible from the beach, (f) Replace pole lamps with low-profile, low-level luminaries so that the light source or any reflective surface of the light fixture is not visible from the beach; (g)Replace incandescent,fluorescent,and high intensity lighting with the lowest wattage low pressure sodium vapor lighting possible for the specific application; (h)Plant or improve vegetation buffers between the light source and the beach to screen light from the beach; (i)Construct a ground level barrier to shield light sources from the beach.Ground-level barriers must not interfere with marine turtle nesting or hatchling emergence,or cause short-or long-term damage to the beach/dune system; 6)Permanently remove or permanently disable any fixture which cannot be brought into compliance with the provisions of these standards. (3)The following measures shall be taken to reduce or eliminate the negative effects of interior light emanating from doors and windows within line-of-sight of the beach: B'ia TAGNMFj ` Jr 42 246
