Few Florida towns list much on the Register (a typical Florida town has 0.0 per 10,000 residents, the U.S. 2.4), so Atlantis’ 0.0 sits below most of its state (33% of Florida towns have fewer) while its 0 listings outnumber those of 23% of U.S. towns.
How sure. Graded on any two of the three inputs instead, the letter would range from D− to D. The pre-1940 share (±1.5 points) is firm at this size. Two sources give 1959.

What stands out about Atlantis’ past
Read from the archive, the National Register and the record. The page puts what stands out first.
The modern history of what became known as the city of Atlantis originates in a ranch called Mulberry Farms, owned by Philip D. Lewis, a former Florida state senator. Lewis's Mission Company raised Brahman cattle on the land. In 1958, real estate developers Nathan Hunt and Paul Kintz purchased the land, which was platted and began the construction of what became a gated golf and country club community. The residential development, combined with a small amount of adjacent land for commercial use, was incorporated on June 19, 1959. Its first council was appointed, consisting of James Kintz as mayor, Nathan Hunt as vice mayor, and councilmen Paul Kintz, Marjorie Hunt, and William Blakeslee.
In 1959, according to Wikidata. the census of 1960 counted 2 people here.
