Mountain View, California
CE&G provided geotechnical engineering services for resurfacing of 6 miles of the San Francisco Bay Trail between Google’s headquarters in Mountain View and Highway 237 in Sunnyvale. The trail is situated atop existing levees owned by United States Fish and Wildlife Service’s Don Edwards San Francisco Bay National Wildlife Refuge and Santa Clara Valley Water District, and is surfaced with gravel. The trail is to be resurfaced with additional aggregate base as required to support PG&E maintenance vehicles and then capped with a smooth aggregate wearing course consisting of stabilized quarry fines. Work included site reconnaissance, 12 shallow hand-dug test holes, laboratory testing, engineering evaluations, and conclusions and recommendations for resurfacing of the trail and stabilizing eroded levee reaches.
