Project Description: The Hyundai/Kia test track is part of a 4,300 acre, $60 million Hyundai/Kia test facility in California City. Vehicles are tested on a variety of surfaces including a 6.4 mile oval track, a 2 million square-foot Vehicle Dynamics Area, a 2.75 mile winding track and a 3.3 mile hill road, and various special surface roads designed to duplicate highway and road conditions. The Proving Ground also includes a 30,000 square-foot office complex for its 50 staff members. Diamond West provided engineering services for the site’s grading, road/street, and storm drain facilities, as well as the storm water pollution prevention plan.

In addition to the on-site development plans, Diamond West prepare the infrastructure design for all off-site improvements, including 2 miles of roadway, water supply pipelines, and storm drains in the road shoulder.

The project site included habitat for the federally and state protected desert tortoise and Mohave ground squirrel. Diamond West worked closely with the environmental consultant in the site design and preparation of a Habitat Conservation Plan that mitigated impacts to these habitats.

The project was completed in 2004 with much enthusiasm and has been featured in multiple print and television advertisements by the Hyundai / Kia Motor Company. "California City is honored to be the home of the Hyundai-Kia Motors California Proving Ground," said Larry Adams, mayor of California City. "For the past two years, Hyundai and Kia have been welcome neighbors, and we look forward to working with them in the years to come."
