Florida Water Management District as conservation easements, and the District collects data and ensures that large portions remain in their natural wetland state. 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 winds. Hurricane Charley (2004) reached maximum sustained winds estimated 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 2018 version. 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 are managed through Reedy Creek Energy Services, which has been merged with the Walt Disney World Company 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). 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). Fire department The Reedy Creek Fire Department (RCFD) was created in 1968 to provide fire suppression for RCID. Today, RCFD provides fire suppression, emergency medical services, 911 communications, fire inspections,
