SUBSURFACE EXPLORATION

Typically, it is necessary to see the subsurface soil to understand understand
what is causing cracks or other damage at the ground surface. Examination via
borings or trenches is used to do so.




AFTER CONSTRUCTION FAILURES

Some issues show up years after construction because active faulting,
landslides, soil creep or other engineering problems manifest over long periods.
As you can see from just a few pictures such problems show up in various ways.




HIGHWAY CONSTRUCTION PROJECTS

Design and construction of highways, bridges, dams and power generation and
transmission fascilities, water treatment plants, landfills, pipelines and other
engineering projects are preceded by geoloigc investigations.



I have conducted hundreds of site-specific geologic investigations involving
subsurface exploration regarding active faulting, land sliding, soil creep,
liquefaction, settlement, ground water contamination and other engineering
problems.  Many of the geologic studies I have conducted were done prior to
design and construction of projects as well as during construction and after
construction (performance problems)  involving residential subdivisions,
highways, bridges, dams, power-generation and transmission facilities, water
treatment plants, landfills, pipelines, and other civil engineering projects.

SUMMARY OF WORK EXPERIENCE: 



I have been responsible for:

 * coordinating and performing various types of field exploration,
 * supervising technical staff,
 * directing laboratory testing,
 * interpreting test results,
 * formulating conclusions and recommendations,
 * preparing illustrations,
 * writing reports.
 * testifying as an expert in public hearings, depositions, and courtrooms, and
 * addressing the public,
 * technical reviews of hundreds of geologic and geotechnical reports prepared
   by private consultants for project applications being processed by local
   governmental agencies.

As County Geologist in the Santa Clara County Planning Office, I reviewed
applications and plans for building permits and land use applications, required
submission of geologic reports, reviewed geologic and geotechnical reports,
determined compliance with State laws and local ordinances, and formulated
Conditions of Approval.  I compiled geologic map information and updated the
County Geologic Hazard Zones.  I facilitated public internet access to County
hazard maps and data.  I reviewed State Preliminary Seismic Hazard Zones Maps
and suggested revisions.  I used State Official Seismic Hazard Zones to revise
County Landslide and Liquefaction Hazard Zones.  I assisted applicants and
consultants by providing site-specific geologic information and access to
reports on file in the County Planning Office.
