Using Data

Using data from surveys conducted in 2004 and 2006, we examine the work and earnings of drayage drivers at the ports of Los Angeles and Long Beach. Though possessing relatively low levels of education (most have a high school diploma or less), these drivers average approximately $35,000 in earnings net of truck expenses, working on average 11.2 hours per day. Owner operators experience increased net earnings once their trucks are fully paid for, leading them to buy older, more polluting trucks. This negative externality is currently being addressed by both ports by enacting new regulations regarding truck drayage in Southern California.

ABSTRACT The large number of oil refineries in Southern California, lack of deepwater port facilities for very large crude carriers, and the large amount of crude oil now available from the Alaska pipeline have necessitated the development of a full-time lightering operation in the lee of San Clemente Island. The three companies presently involved—Shell, Chevron, and Coastal States Gas Corporation—have submitted operation manuals for lightering and contingency plans for handling emergency situations and oil spills. The Southern California Pollution Contingency Organization, an oil cleanup cooperative based in Long Beach, has been contracted by the lightering companies to respond in the event of an oil spill. Each lightering operation consists of a number of phases and requires expert lightering masters and an experienced crew. Since the first lightering on July 22, 1976, Coast Guard boarding teams from both the Los Angeles Captain of the Port Office and the San Diego Marine Safety Office have boarded and monitored more than 70 lighterings. The safety record has been impressive: there have been no major spills and relatively few deficiencies uncovered during tankship examinations.

In 1916, Cornelius Birket Johnson, a Los Angeles fruit farmer, killed the last known grizzly bear in Southern California and the second-to last confirmed grizzly bear in the entire state of California. Johnson was neither a sportsman nor a glory hound; he simply hunted down the animal that had been trampling through his orchard for three nights in a row, feasting on his grape harvest and leaving big enough tracks to make him worry for the safety of his wife and two young daughters. That Johnson’s quarry was a grizzly bear made his pastoral life in Big Tujunga Canyon suddenly very complicated. It also precipitated a quagmire involving a violent Scottish taxidermist, a noted California zoologist, Los Angeles museum administrators, and the pioneering mammalogist and Smithsonian curator Clinton Hart Merriam. As Frank S. Daggett, the founding director of the Los Angeles County Museum of History, Science and Art, wrote in the midst of the controversy: “I do not recollect ever meeting a case where scientists, crooks, and laymen were so inextricably mingled.” The extermination of a species, it turned out, could bring out the worst in people.

Dependent Probability

The San Andreas fault has the highest calculated time-dependent probability for large-magnitude earthquakes in southern California. However, where the fault is multistranded east of the Los Angeles metropolitan area, it has been uncertain which strand has the fastest slip rate and, therefore, which has the highest probability of a destructive earthquake. Reconstruction of offset Pleistocene-Holocene landforms dated using the uranium-thorium soil carbonate and beryllium-10 surface exposure techniques indicates slip rates of 24.1 ± 3 millimeter per year for the San Andreas fault, with 21.6 ± 2 and 2.5 ± 1 millimeters per year for the Mission Creek and Banning strands, respectively. These data establish the Mission Creek strand as the primary fault bounding the Pacific and North American plates at this latitude and imply that 6 to 9 meters of elastic strain has accumulated along the fault since the most recent surface-rupturing earthquake, highlighting the potential for large earthquakes along this strand.
