Ted M. Sayre
Vice President
Principal Engineering Geologist/Geological Engineer
Registration
Registered Geologist in California, RG 5711
Certified Engineering Geologist in California, CEG 1795
Engineer in Training (EIT passed 1986)
Education
M.E., Geological Engineering: Colorado School
of Mines, Golden, Colorado, 1985
B.A., Geology: University of California, Berkeley, California, 1981
Areas of Specialty
Geotechnical peer review and investigation of
proposed development, primarily in hillside areas, potentially constrained
by slope instability, fault rupture, ground shaking and liquefaction
Representative Experience
Mr. Sayre has over 23 years of experience in the
fields of engineering geology, geological engineering, and hydrogeology.
As a principal engineering geologist with Cotton, Shires and Associates,
Inc., Mr. Sayre helps to administer a variety of projects. In this
capacity, he is responsible for overall project supervision and
coordination, compilation, collection and analysis of geologic and
geotechnical data, and preparation and presentation of technical
maps and reports. In addition, his duties include analysis of aerial
photographs, field mapping of bedrock and surficial deposits and
subsurface geologic exploration.
Mr. Sayre uses his combined background of engineering
geology and geological engineering to investigate and resolve interrelated
geologic and geotechnical issues. This background is especially
useful when investigating landslide or seismic hazards that require
close coordination between geologic characterization and engineering
mitigation of the hazard. As a geologist, he has worked on a variety
of projects in Alaska, California, Hawaii, Nevada, and Oregon. As
a geological engineer and hydrogeologist with the U. S. Geological
Survey Nuclear Hydrology Program, Mr. Sayre conducted research to
investigate water flux through the unsaturated zone at Yucca Mt.,
Nevada. This work was part of a detailed characterization program
to evaluate candidate sites for the nation's first high-level nuclear
waste repository.
Mr. Sayre currently is responsible for the coordination
of geotechnical peer review, including evaluation of proposed land
divisions and building permit applications, for several San Francisco
Bay Area communities. Proper recognition, characterization and mitigation
of unstable ground are topics Mr. Sayre critically examines in his
review capacity on a regular basis. In addition, evaluation of other
common Bay Area seismic hazards such as surface fault rupture, amplified
ground shaking, liquefaction and seismically induced slope failure
are also part of Mr. Sayre's responsibility as a quality control
reviewer of development safety. After the 1989 Loma Prieta earthquake,
Mr. Sayre worked with the Santa Cruz County Earthquake Recovery
Unit as a Supervising Engineering Geologist where he assisted in
technical review of hundreds of building permit applications for
repair of seismically damaged structures. More recently, Mr. Sayre
has completed many residential damage assessments for local communities
impacted by El Niño induced landslides.
