Superintendent Alan Bersin has finally sold his Point Loma house and moved into a manse down the hill in La Playa overlooking San Diego Bay. The controversial school honcho got $1,250,000 in September, when he sold the house he bought for $535,000 ten years ago. He's moved into a home owned by greengrocer Ron Cohn, owner of Henry's market in Chula Vista. Cohn also owns another Point Loma home at 3250 McCall Street designed by renowned 84-year-old La Jolla architect Robert Mosher. Last February, the San Diego City Council voted 7-2 to approve Cohn's request that they block the 52-year-old house's official historical designation so that Cohn and his wife Guadalupe could tear it down or at least build a second story to take advantage of the view. "We instantly fell in love with the views and large lot," he told reporters before the council vote. Mosher said he was outraged by the mere suggestion of altering his masterpiece. "It didn't occur to me that someone would consider tearing it down," he told the Union-Tribune. "The idea was appalling to me." Reached by phone in his produce department last week, a busy Cohn said that he still hasn't done any work on the $1.6 million house; historical preservationists have managed to stymie his home-improvement plans by taking their case to the state historic preservation office, he said. Asked about his famous tenant, he hung up the phone.
