Three years after a devastating landslide killed 10 people in Ventura County, the owners of an avocado ranch above the coastal hamlet agreed Monday to turn over all 700 acres of their land and other assets to settle a lawsuit. The move effectively puts La Conchita Ranch Co. out of business... Monday's agreement follows an Aug. 19 jury verdict that found La Conchita Ranch Co. was 50% negligent in the landslide because it didn't provide for adequate drainage of its orchards during torrential rains that swept over Southern California... The jury exonerated ranch manager David Orr of any negligence.
