SAN JOSE, Calif. -- Officials at San Francisco-area locations that 2012 Olympics organizers have said would house athletes or host events at the games say they haven't guaranteed the sites are available.

Trustees with Santa Clara's Mission College say they were surprised to learn the nonprofit group trying to bring the games to Northern California told the United States Olympic Committee the campus would be home to its $47-million tennis venue.

"It is a completely false presentation," said trustee Jeffrey Schwartz.

The U.S. Army, which controls the former base where the Bay Area Sports Organizing Committee hopes to build an $830- million Olympic village for thousands of athletes and staff, say they've never said the land was available.

Maj. Jeff Cooper, the Army housing project manager for Moffet Field, said the land currently is earmarked for military housing.

"I hope they win if that's what the Bay Area wants. But my job as a housing project officer is to ensure the quality of life for military personnel in the South Bay. That's what the property is here for," Cooper told the San Jose Mercury News.
