Florida City is situated mostly atop a limestone ridge called the Miami Rock Ridge that extends south from present day North Miami Beach to a location in Everglades National Park. The ridge, consisting of Miami limestone, serves as the higher ground within the community. The ridge extended from northeast to southwest across the city. The old location of the Florida East Coast Railway track marks the approximate boundary of the location of the limestone ridge south of Davis Parkway. The range of elevation of the ridge is from 5 to 8 feet (1.5–2.4 meters) above sea level.
