§ 46-95. Existing development.  


Latest version.
  • The following artificial lighting standards shall apply to all existing development:

    (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 exceeding 50 watts.

    d.

    Replace nondirectional fixtures with directional fixtures that point down and away from the beach.

    e.

    Replace fixtures having transport 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.

    f.

    Replace pole lamps with low profile, low level luminaries so that the light source or any reflective surface 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 light 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 when possible. 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.

    j.

    Permanently remove or permanently disable any fixture which cannot be brought into compliance with the provisions of these standards.

    k.

    Extinguish the fixture(s) after 9:00 p.m. during the period of May 1 to October 31 of each year.

    (3)

    The following measures shall be taken to reduce or eliminate the negative effects or interior light emanating from doors and windows within line-of-sight of the beach.

    a.

    Apply window tint or film that meets the standards for tinted glass.

    b.

    Rearrange lamps and other moveable fixtures away from windows.

    c.

    Use window treatment (e.g., blinds, curtains) to shield interior lights from the beach.

    d.

    Turn off unnecessary lights.
