Port St. Lucie, FL Outdoor Lighting: Billboard Lighting (2026)

08(S)(6) states the rule in a single sentence: lighting shall be shielded and shall not be directed at any area with residential, institutional, or commercial land use or zoning nor at any public or private road right-of-way. 08(S), whether the illumination comes from external floodlights aimed at a static print face or from an internally lit display; the shielding duty is about where the light lands, not how it is generated. Because subsection (S) also confines billboards to sites within 200 feet of the Florida Turnpike or I-95 right-of-way and at least 200 feet from residential land, the lighting rule works alongside the siting standard to keep highway advertising light from spilling into the adjacent uses the siting rule was already designed to buffer, including the very roadway the sign faces.

08(I)(4) requires ambient light sensors, automatic dimming, and numeric nighttime and daytime luminance ceilings for message boards on institutional freestanding signs, but the billboard subsection does not import those numeric caps for billboards. 137 of the zoning code, since a design that cannot demonstrate compliant shielding does not meet the regulations the special exception is conditioned on. The body reviewing the special exception can deny or condition approval on lighting fixtures, angle, and glare-control measures that satisfy the no-spillover standard before the billboard is ever built.
