After several years of controversy involving previous geotechnical peer review consultants, City Engineer, Mark Lander, of the City of Dublin turned to Cal Engineering & Geology to provide an independent third party review of the planned Fallon Village Development project in the east Dublin hills. CE&G met with the developer’s geotechnical consultant and the City to understand the scope of the project from a geotechnical perspective and then completed a geotechnical peer review of planned mass grading for the development which was to be completed over several years. Based on the review, the scope of remedial grading and monitoring of deep fills at the site were revised and grading permits were issued.
During the mass grading operations for the project, CE&G Principal Geologist, Mitch Wolfe, has been providing special geological observations on behalf of the City. The geologic observations have been focused on confirming subsurface conditions during grading and reviewing during–grading modifications proposed by the developer’s geotechnical consultant. Grading has taken place over several years and includes over 8 million cubic yards of earthwork and repair of numerous large ancient bedrock landslides in a hillside environment. After the completion of the project, a Geologic Hazard Abatement District (GHAD) will be created. CE&G has reviewed the proposed Plan of Control and Engineer’s Report which will form the basis of the GHAD formation and provided detailed recommendations to the City regarding suggested changes to the those documents prior to their approval and adoption.
