Yeah, this is already happening in Disney World: https://en.wikipedia.org/wiki/Reedy_Creek_Improvement_Distri...

> On March 11, 1966, these landowners, all fully owned subsidiaries of what is now The Walt Disney Company, petitioned the Circuit Court of the Ninth Judicial Circuit, which served Orange County, Florida, for the creation of the Reedy Creek Drainage District under Chapter 298 of the Florida Statutes. After a period during which some minor landowners within the boundaries opted out, the Drainage District was incorporated on May 13, 1966, as a public corporation. Among the powers of a Drainage District were the power to condemn and acquire property outside its boundaries "for the public use". It used this power at least once to obtain land for Canal C-1 (Bonnet Creek) through land that is now being developed as the Bonnet Creek Resort, a non-Disney resort.[3]

> However, Walt Disney knew that his plans for the land would be easier to carry out with more independence. Among his ideas for his Florida project was his proposed EPCOT, the Experimental Prototype Community of Tomorrow, which was to be a futuristic planned city (and which was also known as Progress City).[4] He envisioned a real working city with both commercial and residential areas, but one that also continued to showcase and test new ideas and concepts for urban living.[3] Therefore, the Disney Company petitioned the Florida State Legislature for the creation of the Reedy Creek Improvement District, which would have almost total autonomy within its borders. Residents of Orange and Osceola Counties did not need to pay any taxes unless they were residents of the district. Services like land use regulation and planning, building codes, surface water control, drainage, waste treatment, utilities, roads, bridges, fire protection, emergency medical services, and environmental services were overseen by the district,[3] and the only areas where the district had to submit to the county and state would be property taxes and elevator inspections.[1] The planned EPCOT city was also emphasized in this lobbying effort.

> On May 12, 1967, Governor Claude R. Kirk, Jr. signed the following statutes to implement Disney's plans:[5]

* Chapter 67-764 created the Reedy Creek Improvement District;

* Chapter 67-1104 established the City of Bay Lake; and

* Chapter 67-1965 established the City of Reedy Creek (later renamed as the City of Lake Buena Vista around 1970.)

> According to a press conference held in Winter Park, Florida, on February 2, 1967, by Disney Vice President Donn Tatum, the Improvement District and Cities were created to serve "the needs of those residing there", and the company needed its own government to "clarify the District's authority to [provide services] within the District's limits" and because of the public nature of the planned development. The original city boundaries did not cover the whole Improvement District; they may have been intended as the areas where communities would be built for people to live.[1][3]

> A five-member Board of Supervisors governs the District, elected by the landowners of the District. These members, senior employees of The Walt Disney Company, each own undeveloped five-acre (2.0 ha) lots of land within the District, the only land in the District not technically controlled by Disney or used for public road purposes. The only residents of the District, also Disney employees or their immediate family members, live in two small communities, one in each city. In the 2000 U.S. Census, Bay Lake had 23 residents, all in the community on the north shore of Bay Lake, and Lake Buena Vista had 16 residents, all in the community about a mile north of Disney Springs. These residents elect the officials of the cities, but since they don't actually own any land, they don't have any power in electing the District Board of Supervisors.

> The District headquarters are in a building in Lake Buena Vista, east of Disney Springs.[11] The District runs the following services, primarily serving Disney:

> Law enforcement – Officers from Orange County, Osceola County and the Florida Highway Patrol are contracted to police the district. In addition, the Walt Disney Company employs about 800 security staff in their Disney Safety and Security division. While Disney security maintains a fleet of private security Chevrolet Equinoxes equipped with flashing lights, flares, traffic cones, and chalk commonly used by police officers, arrests and citations are issued by the Florida Highway Patrol along with the Orange County and Osceola County sheriffs deputies.

> Disney security personnel are involved with traffic control and may only issue personnel violation notices to Disney and RCID employees, not the general public.[1] Security vans previously had red lightbars, but after public scrutiny following the death of Robb Sipkema,[12] were changed to amber to fall in line with Florida State Statutes.[13]

> Environmental protection: Many pieces of land have been donated to the Florida Department of Environmental Regulation and the South Florida Water Management District as conservation easements, and the District collects data and ensures that large portions remain in their natural wetland state.[11]

> Building codes and land-use planning – The "EPCOT Building Codes" were implemented to provide the sort of flexibility that the innovative community of EPCOT would require. The provisions contained therein, although rumored to be exceptionally stringent, have in fact never been far and above those of the Standard Building Code or the Florida Building Code (FBC) that is currently in force in the rest of Florida. In fact, since the inception of the International Building Code (IBC) in 2000, the EPCOT Building Code defers much of its design parameters to the IBC-based FBC, and many of the reference standards contained therein. Particularly with regard to wind design, today's standards are better than the ones that previously existed, and today's RCID buildings are built to withstand 110 mph (180 km/h) winds. Hurricane Charley (2004) reached maximum sustained winds estimated 85 mph (137 km/h) at the nearby Orlando International Airport but winds were lower on RCID property. Although the codes are ostensibly updated on a three-year cycle, the most recent and currently used version of the EPCOT Building Codes is the 2015 version.[14][11]

> Utilities – wastewater treatment and collection, water reclamation, electric generation and distribution, solid waste disposal, potable water, natural gas distribution, and hot and chilled water distribution, through Reedy Creek Energy Services, which has been merged with the Walt Disney World Company[11]

> Roads – Many of the main roads in the District are public roads maintained by the District, while minor roads and roads dead-ending at attractions are private roads maintained by Disney; in addition, state-maintained Interstate 4 and U.S. Highway 192 pass through the District, as does part of the right-of-way of County Road 535 (formerly State Road 535).[11]
Disney provides transportation for guests and employees in the form of buses, ferries, and monorails, under the name Disney Transport. In addition, several Lynx public bus routes enter the District, with half-hour service between the Transportation and Ticket Center (and backstage areas at the Magic Kingdom) and Downtown Orlando and Kissimmee, and once-a-day service to more points, intended mainly for cleaning staff. Half-hourly service is provided, via Lynx, to Orlando International Airport (MCO).[11]
