In order to provide the highest level of protection for nesting marine turtles and their hatchlings, the county hereby adopts all of the following standards for existing artificial lighting sources, including utility leased lighting, seaward of the CCCL.
(A) Existing artificial light fixtures shall be repositioned or modified so that:
(1) The point source of light or any reflective surface of the light fixture is not directly visible from the beach;
(2) Areas seaward of the frontal dune are not directly or indirectly illuminated; and
(3) Areas seaward of the frontal dune are not cumulatively illuminated.
(B) The following measures may be taken to comply with this section:
(1) Reposition fixtures so that the point source of light or any reflective surface of the light fixture is no longer visible from the beach;
(2) Replace fixtures having an exposed light source with fixtures containing recessed light sources or shields;
(3) Replace traditional light bulbs with yellow “bug” type bulbs not exceeding 25 watts;
(4) Replace non-directional fixtures with directional fixtures that point down and away from the beach;
(5) 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 light source or any reflective surface of the light fixture is not visible from the beach;
(6) 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;
(7) Replace incandescent, fluorescent and high intensity lighting with the lowest wattage low-pressure sodium-vapor lighting possible for the specific application;
(8) Permanently remove or permanently disable any fixture which cannot be brought into compliance with the provisions of these standards; and
(9) Disconnect utility leased lighting during the marine turtle nesting season.
(C) The following measures shall be taken as applicable to reduce or eliminate the negative effects of interior light emanating from doors and windows within line-of-sight of the beach:
(1) Apply window tint or film that meets the standards for tinted glass;
(2) Rearrange lamps and other moveable fixtures away from windows;
(3) Use window treatments (e.g., blinds, curtains) to shield interior lights from the beach; and
(4) Turn off unnecessary lights.
