SAN FRANCISCO -- City officials have temporarily evacuated a condominium building at the base of San Francisco's Telegraph Hill after several boulders slid down the hill and crushed a parked car, authorities said. The boulders, apparently loosened by the weekend rain, slid down the hill near Lombard and Montgomery streets around 9:30 a.m., officials said. No one was hurt. The bottom floors of a multistory condo complex at 240 Lombard St. next to the hill has been evacuated while engineers from the city determine if any more boulders could fall, officials said.
