The Leisure World
About 90% of the city consists of Laguna Woods Village, a retirement community, formerly known as Leisure World. Incorporation efforts in the late 1990s were largely driven by the need for residents to have a stronger voice against the prospective construction of an international airport at the nearby decommissioned Marine Corps Air Station El Toro.
