Section 14-55. new development.
(a) It is the policy of the city to minimize artificial light illuminating within the jurisdictional boundaries of this article to reduce artificial light on the beaches. To meet this intent, building and electrical plans associated with parking lots, dune walkovers or other outdoor lighting for development of real property within the jurisdictional boundaries shall be in compliance with the following:
(1) Except as set forth in subsection (a)(2) of this section, no more than 0.5 footcandles of artificial illumination shall be cast upon the beach. Appropriate techniques for reducing artificial illumination include but are not limited to fitting lights with hoods or shields, screening artificial light with vegetation or other devices, directing light away from beach area, utilizing low-profile lighting and lowering the light intensity of the lamps.
(2) No more than two footcandles of artificial illumination shall be cast upon the beach when the spectral distribution of the light bandwidths is between 560 and 620 nanometers. commercially available lighting that satisfies the spectral criteria include low-pressure sodium lamps.
(3) No lamp shall be directly visible from the beach. The use of opaque materials for screening and hooding the lamps are techniques which may be used to limit visibility from the beach.
(4) parking lots where vehicle headlights may cast light onto the beach so as to be in violation of this article shall be screened to eliminate excess light on the beach.
(5) At the time building and electrical plans are submitted for public review, appropriate photometrics of the artificial lighting used shall be provided by the applicant. photometrics shall include horizontal isolux charts and spectral distribution charts if appropriate.
(b) This article shall not apply to any structure for which a building permit or development order has been issued prior to the effective date of the ordinance from which this section is derived.
