Protecting our land for generations to come

At Campbell Grading, Inc., we are privileged to work in some of the most beautiful and sensitive areas in California. We have executed projects at sites ranging from remote backcountry to heavily trafficked urban areas. Our focus on all projects, from habitat restoration to trail design and construction, is on protecting the essence of these treasured spaces and ensuring their continued use by generations to come.

Campbell Grading, Inc., has a 30-year history of trail construction and habitat restoration projects throughout the greater Bay Area.  Barth Campbell started the company with the intent of providing clients with sound engineering, sustainable projects, and high-quality service.  Over the decades, this commitment to quality has fused with Barth’s deep and abiding respect for nature and the environment. Now we contract almost exclusively with public and nonprofit organizations to improve and protect the environment and the public’s access to it.


When Campbell Grading, Inc., employees were asked what they enjoy about their jobs, they all said the small size of the company. They like working closely with owner Barth Campbell and enjoy the company of their coworkers. In addition, our employees enjoy the locations they get to work in, and they like taking part in the transformation of these sites from start to finish.
