California Geological Survey :
District Geologist for San Francisco Bay (1982-1988), and Senior Engineering Geologist (1989-2007) in Sacramento
Managed the San Francisco Bay regional office of the California Geological Survey (then located in the Ferry Building, the Embarcadero and Market Street, San Francisco). Supervised the Regional Geologic Mapping Program, the Alquist-Priolo Earthquake Fault Mapping Program, and the Timber Harvest Mapping Program (geologic mapping for California Department of Forestry). Moved the State Mineral Museum to Mariposa, near Yosemite National Park (a very controversial transfer, involving litigation from citizens in San Francisco). Supervised the field work on the 1983 Coalinga Earthquake and the 1983 landslides in Santa Cruz County. Moved 38 employees and the Geology Library to Pleasant Hill in 1984, in response to orders from Sacramento (= state budget cuts).
In 1988, was transferred to Sacramento headquarters of the California Geological Survey, and moved my family from Walnut Creek to Fair Oaks. Worked for months in Santa Cruz in the aftermath of the October 1989 Loma Prieta Earthquake. Was co-editor and author of Special Publication 104 on the Loma Prieta Earthquake, 140-page monograph. Worked 4 years with the California Strong-Motion Instrumention Program, performing geologic field work in the aftermath of the 1992 Cape Mendocino Earthquake, the 1992 Landers Earthquake, and the 1994 Northridge Earthquake. Transfered in 1994 to performing hospital and public school review work for OSHPD and DSA (respectively). Edited and prepared a new edition of Note 48 Checklist for Review of Hospitals, Public Schools, and Essential Services Buildings.
Retired in August 1997 after 25 years of state government service. Am now a consulting engineering geologist in private practice.
Worked four years on the Alaskan Natural Gas Pipeline. Spent summers in central Alaska and Atigun Pass in the Brooks Range; spent winters back home in Irvine, Orange County, California. Worked on geologic mapping of the 700-mile pipeline corridor in a swath that was 3 miles wide. Mapped permafrost and Quaternary geology formations in Central Alaska, plus rock-slope engineering at Atigun Pass. Was involved in mapping of active fault crossings for the proposed pipeline route. Worked on permafrost hydrogeology of how the chilled gas pipeline would create its own frozen annulus, with interruption of the summer seasonal cross-flow of surface water. Resigned in October 1982 to accept a promotion as the District Geologist for San Francisco of the California Geological Survey.
Leighton & Associates; Irvine, Orange County, California :
Staff Engineering Geologist
Worked principally on residential hillside development, with emphasis on landslides, deep foundations, and active faults. Work are was principally in the Puente Hills, the Santa Ana Mountains, San Mateo County, Santa Clara County, and the Riverside-San Diego area. Preprepared seismic safety elements for several cities and counties in California. Resigned to accept a promotion to become Orange County Geologist in 1977.
Mobil Oil Corporation, Alaska Division (based out of Anchorage, Alaska) :
Summer Field Geologist, Petroleum Exploration
Summer of 1970: Work in the Alaska Peninsula, Bristol Bay, and Cook Inlet areas as a summer field geologist for Mobil Oil Corporation. Summer 1970: worked in Central Alaska, on a voyage up the Yukon River, from Saint Mary's (on the Yukon Delta) all the way to Fort Yukon. Was part of a 22-man field crew of geologists and geophysicists. Work involved regional geologic mapping, measuring and sampling stratigrapic sections, collecting fossils, and performing a gravity survey. Each September, I returned to graduate school in the Department of Geological Sciences at the University of California, Riverside.
