Cornerstone Earth Group, Inc. is providing environmental and geotechnical services for the City of San Jose on the planned Taxiway V extension at the San Jose Mineta International Airport in support of our client, Kimley-Horn. The project consists of the removal of the existing parallel taxiways, constructing new taxiways, extending Taxiway V into the current grass infield areas, and rehabilitating some of the existing connecting taxiways. Cornerstone evaluated the physical properties of sub-surface soils and furnished recommendations for site work, grading activities, and pavement.
