Project Experience:


Coyote Valley Specific Plan—San Jose, CA.

ENGEO provided the preliminary geotechnical/geological feasibility assessment for the Coyote Valley Specific Plan area (CVSP) which will consist of industrial, mixed-use urban, and open space preservation areas. The site will include roughly 25,000 new homes, park and school facilities, rail/light rail transit extensions and upgrades, emergency response sites and 1,400 acres of commercial facilities anticipated to bring 50,000 new jobs to the Coyote area.

Yosemite National Golf and Wetland Preserve Groundwater Study—Jamestown, CA.

ENGEO is providing a geotechnical and geologic groundwater resource and effluent disposal study for the proposed Grand Yosemite National Golf and Wetland Preserve.  The site consists of approximately 500 acres located near the intersection of Highway 108 and Highway 120.  The project will consist of constructing a golf course, a multi-story hotel, multiple vacation ownership buildings, approximately 60 one- to two-acre residential lots, a wastewater treatment facility and other related structures.

The Villages at Squaw Valley—Olympic Valley, CA.

ENGEO performed geotechnical studies for this world-class village and addressed environmental contaminants within the project area.

We conducted numerous ground water studies to solve earthwork and construction issues in advance, and developed a “one-of-a-kind” foundation solution for the parking garage saving our client over $750,000.
