This is a seperate zoning layer from the rest of the county as it has different categories. Santa Catalina Island falls under a specific plan (22.46.050 et.al.), which designates land use districts for the unincorporated area of the island. These land use districts serve the same role as zones, but supersede the basic zones in Title 22. This has been in effect as of the adoption of the Santa Catalina Island Specific Plan in 1989.
