Lake Buena Vista is a city in Orange County, Florida, United States. It is mostly known for being the mailing address for the Walt Disney World Resort—although almost all of the resort facilities, including all four theme parks, are physically located in the adjacent city of Bay Lake. It is one of two Florida municipalities controlled by The Walt Disney Company, the other being Bay Lake. The permanent residential population of Lake Buena Vista was 10 at the 2010 census.Lake Buena Vista is part of the Orlando–Kissimmee–Sanford Metropolitan Statistical Area.HistoryChapter 67-1965 of the Laws of Florida, incorporating the City of Reedy Creek, was signed into law by Governor Claude R. Kirk, Jr. on May 12, 1967, the same day he also signed chapters 67-764 (creating the Reedy Creek Improvement District) and 67-1104 (incorporating the city of Bay Lake). It was located fully inside the Reedy Creek Improvement District. The city was controlled by the Walt Disney Company and allowed it powers that other area attractions had not had.Chapter 69-1527, which became a law on July 3, 1969, without the governor's approval, redefined the city boundaries. The city was completely moved, taking over some land that had been part of the City of Bay Lake (and was given up by Chapter 69-836, which became a law the same day) and including some other land that had formerly been unincorporated. Soon after, the City of Reedy Creek was renamed to the City of Lake Buena Vista to better reflect its new location, through which Reedy Creek did not flow. "Buena Vista" comes from the name of the street in Burbank, California, where the Walt Disney Company is headquartered.
