Atlantic Beach is located in Duval County, Florida and part of the Jacksonville Beaches communities. When the majority of communities in Duval County consolidated with Jacksonville in 1968, Atlantic Beach remained quasi-independent and still maintains its own municipal government today. Much of the development in the city has been residential, with single-family homes accounting for most of the developed land areas. The city is nearing build-out with less than 10% of the incorporated land area being undeveloped. The island is experiencing on-going development including a nature park with trails, a floating dock for launching kayaks and canoes, a fishing pier, camping sites and pavilions. Residents may now enjoy more than sixty-five acres of parkland.
