In an effort to keep Boeing's world headquarters on the West Coast, representatives from Los Angeles Mayor Richard Riordan's office have suggested four potential real estate sites to Boeing in a variety of Southland areas.

Jeff Walden, Riordan's assistant deputy mayor and leader of the city's new business team, said a large piece of one of the sites - in the Harbor Gateway area near San Pedro – was already owned by Boeing. The company accumulated a significant amount of real estate when it merged with McDonnell Douglas in August 1977.

"There is some existing space already on the property," Walden said, "but Boeing could easily build another 400,000-500,000 square feet without any problem."
