Soka University of America(SUA), originally called Soka University of Los Angeles (SULA), initially operated a small ESL (English as a Second Language) school at the Calabasas campus, enrolling just under 100 students. In 1990, SUA announced plans to build a future liberal arts college on campus and plans to expand the facility over the next 25 years to an enrollment of as many as 5,000 students. SUA began making plans to expand the campus infrastructure to accommodate living quarters and classrooms for the proposed expansion, but ran into opposition from some local residents, the Santa Monica Mountains Conservancy, environmentalists, and government representatives. Opponents sought to protect the Chumash ancestral site, the natural habitats and ecology, and the expansive open space viewshed within the Santa Monica Mountains National Recreation Area, and to prevent a development of unprecedented urban density adjacent to Malibu Creek State Park.
