Thursday, October 4th, 2007 — A landslide swept away a chunk of an upscale hilltop neighborhood Wednesday, opening up a 50-yard chasm in a four-lane road, damaging or destroying nine homes and forcing the evacuations of 111 houses. No one was hurt in the collapse, which occurred the morning after city officials warned residents of four homes in the La Jolla neighborhood not to sleep in them because the land might give way.
