GEOTECHNICAL EVALUATION OF OPEN SPACE LAND, PINOLE CA
Mr. Ryan prepared landslide and erosion maps of the open space land owned by the
MHOA based on aerial photograph interpretation and field reconnaissance. Based on the
information produced he was contracted by the MHOA Board of Directors to provide
input regarding methods to deal with the issues both politically and technically.
LANDSLIDE INVESTIGATION, CONTRA COSTA COUNTY, CA
Mr. Ryan was the principal investigator leading a team of five experienced licensed
engineering geologists in the investigation of ancient bedrock landslides. His role
included directing the field subsurface investigation, logging the core samples, and
producing the final subsurface geologic interpretation.
Mr. Ryan’s data and
interpretation were utilized in the successful stabilization of the landslides.
DESIGN-LEVEL GEOTECHNICAL INVESTIGATION, UOP PROPERTY,
PETALUMA, CA
Mr. Ryan performed the preliminary and design-level geotechnical investigations for this
project. He directed the field investigation and managed project budgets. Project results
included geotechnical recommendations for, site preparation and remedial grading,
keyway construction, sedimentation hazards and creek setbacks.
LANDSLIDE STABILIZATION FOR FALLON ROAD BRIDGE, DUBLIN, CA
Mr. Ryan conducted engineering geologic review of excavations performed during
remedial grading of ancient bedrock landslides in the Tassajara formation. The ancient
bedrock landslides were located within the alignment for the Fallon Road extension and
impacted construction of both bridge abutments. Mr. Ryan’s role was to determine when
the keyway excavations had penetrated to below the landslide slip surface and when
removal of the landslide materials had been achieved. He correctly identified the base of
the ancient landslide and approved the excavation for compliance with previous
geotechnical recommendations.
TASSAJARA CREEK BANK STABILITY EVALUATION, DUBLIN, CA
Mr. Ryan performed geomorphic mapping of a two-mile stretch of Tassajara Creek to
delineate erosional features such as meander scars and incised channels, terrace deposits,
