Angel Island

Angel Island, in San Francisco Bay, has a long and storied history. It was a Miwok hunting ground three thousand years ago, and has since served in a number of capacities in the Civil War, Spanish-American War, and World War II. It also acted as a major immigration point for the west coast in the first half of the 20^th century. After World War II, the island served as a Nike missile site and remained this way until it was turned over to the State of California in 1962.

For this project, Campbell Grading Inc. was contracted to reconstruct the original contours of Mount Livermore on Angel Island and recover 80,000 cubic yards of fill that had been pushed over the island’s North slope. This fill was pushed over the slope in order to accommodate a radar stations at the top of the island.

Barth Campbell developed an innovative approach that created a series of 5 benches, reducing costs while stabilizing and establishing natural contours.  Heavy equipment was mobilized to the island via barge. This project involved protection of historic resources, hydrologic restoration, and coordination with multiple project partners. These partners included Sonoma County Probation crews, State Parks maintenance crews, and other contracted labor.  Erosion control was installed on 7 acres and the project was completed on time and within budget.
