La Conchita landslides

"[1] La Conchita is a small community located on the southern California coastline between Ventura and Santa Barbara.

[2] It lies on a narrow strip of land about 250 meters (820 feet) wide between the shoreline and abutting a 180-meter (590 ft) high bluff.

The bluff above La Conchita has a slope of approximately 35 degrees and consists of poorly cemented marine sediments.

[4] In 1994–1995, the seasonal rainfall at Ojai (20 kilometers (12 miles) northeast of La Conchita) from October 1 through March 3 (the day before the landslide occurred) was 761 millimeters (29.96 inches), approximately twice the normal amount.

On March 4, 1995, the hill behind La Conchita failed, moving tens of meters in minutes, and buried nine homes with no loss of life.

[citation needed] Days later, on March 10, a subsequent debris flow from a canyon to the northwest damaged five additional houses in the northwestern part of La Conchita.

In March 2006, Governor of California, Arnold Schwarzenegger, allocated $667,000 for a scientific study to determine control measures to be taken to prevent future landslides.

[5] The Ranch was found 50% negligent because it did not provide for adequate drainage of its orchards during torrential rains and settled the suit.

Three years after the 2005 landslide, the owners of an avocado ranch agreed to turn over all 700 acres (280 ha) of their land and other assets to settle the suit.
