Malibu

General Motors Corp. wants to build a 108,000-square-foot headquarters for its Advanced Concept Center on a 22.5-acre site in Malibu, at the southeast corner of Pacific Coast Highway and Malibu Canyon Road.

The center, established last September and temporarily based in Newbury Park near Thousand Oaks, employs 24 people “on a special mission to work on transportation concepts for the year 2000 and beyond,” said GM spokesman Harry Kelly.

Though it is run by GM’s design staff in Detroit, “we’re out here because we know the trends of the future start in California,” said center director Henry Haga. Eventually, the work force will expand to about 75.

GM has an option to buy the property, but the land may be rezoned from science and research to visitor-serving commercial under a proposal adopted by the California Coastal Commission last week. The Board of Supervisors must reach agreement with the commission, however, before the proposal takes effect.
