• Defining "directly visible" and "indirectly visible" light as it pertains to illumination of the beach, and regulating against both direct and indirect illumination of the beach. ; • Requiring all exterior light fixtures, on both new development and existing development structures, to be lamped with a long wavelength light source, such as amber or red light emitting diodes (LED), low pressure sodium, or true red neon. The FWC further recommends that no such light source emit light below 560 nanometers (nm), and that recommendation is stated in the proposed ordinance. The draft ordinance that was presented to the PZC at the PZC's June 11, 2015 public hearing has since been revised to incorporate the PZC's ordinance-related recommendations and also to address comments received by FWC staff. Attachment 6 to this report highlights (in yellow) the changes made in the proposed ordinance to address FWC comments. ANALYSIS The primary direction from the Board of County Commissioners to staff in revising the sea turtle protection lighting regulation focuses on how "illumination" is defined, measured, and applied to beachfront lighting, particularly relating to interior lighting, which was the specific issue in the citation appeal described herein. The proposed revisions address that issue, but also include other revisions explained later in this report. ! Comparison to State Model Ordinance and Other Local Ordinances j In drafting the proposed ordinance revisions, staff reviewed the state's model sea turtle lighting ordinance (Florida Administrative Code Chapter 6213-55, Attachment 5 to this report), as well as other local ordinances in the region. The following chart provides a comparison of the state model ordinance and other local sea turtle protection ordinances to Indian River County's current ordinance and to the proposed revisions, particularly relating to beach illumination and interior lighting restrictions on existing development. =u - /� ....n.,: W�,. �C.'�1��- p rison of`Sea Turtle;Protection Li htm' sR lations•�( � � of n j i f' 's + 5� _ �v ��i i (D t ons;oftllum�natioo adresfrict�ons o interior lighting) • ori- - `'f- r"+T'',��•-•'��}'-�irs-'��,:_:ti ��;�%�s.�,��}',j;;� ,,�n+t-%��- �r t'-�§ a4-`;' g� .._ :. ... :: - _-?'^d.':a�•x�-:e��C•nr14."ac.Ei--�. � Y�� ^�s�;'X�t�Rc",�M�.�'�S_�+ .�';$gt.1p J mute-___.r1i w.t�...•.
