The bill establishes a new section in the Florida Statutes, specifically section 258.603, which designates a mangrove island adjacent to the Intracoastal Waterway within Jupiter Sound as the Andrew Red Harris Spoil Island. This designation aims to recognize the island's significance and ensure its preservation.

Additionally, the bill mandates that the Department of Environmental Protection is responsible for erecting suitable markers to officially designate the Andrew Red Harris Spoil Island as outlined in the new section. The act is set to take effect on July 1, 2026.
