The California Trail at the Oakland Zoo won Engineering News Record's (ENR) Regional Best Project Award in the Cultural Category at the Julia Morgan Ballroom, San Francisco California, October 9, 2018. More than 20 years in the making, the $72 million project was a culmination of community collaboration and the perseverance of the Conservation Society of California. The project includes 26 structures on 22 acres of land and an aerial gondola system. Finished on time and under budget, the California Trail project doubles the size of the zoo complex to roughly 100 acres and furthers the zoo's mission of conservation, education and research with a focus on native California animals. Eight native engdangered and threatened California species - gray wolf, grizzly bear, black bear, mountain lion, bison, jaguar, California condor, and bald eagle - live amid rolling hills and oak habitat of the Oakland Zoo's California Trail.
