Unincorporated islands are pockets of County territory that are surrounded or adjacent to cities. The residents in these islands receive their services from the County. Currently, there are 33 unincorporated islands located in or adjacent to 18 different cities in Orange County.
In June 200, the Commission initiated the Unincorporated Island Program as part of its Strategic Plan. The program has resulted in the successful annexation of 43 unincorporated islands. The Program has been very successful in diminishing the number of unincorporated islands and will continue to be successful for the remaining islands. This webpage provides island location maps, island site photos and 2015 Census demographic and service data.
