Coast, a fuse manufacturer, outgrew its Oakland plant and moved to Livermore in 1913. The 310 acre site in East Livermore provided room for the plant, test bunkers, and management housing, as well as fruit and walnut orchards.
Coast built and owned the management houses on Trevarno Road, and was responsible for all maintenance from light bulbs to additions. Three full-time gardeners were on site for the upkeep of lawns and trees.
Coast entered the textile industry in 1947 by weaving fiberglass fabric. The plant was first leased to, then sold to Hexcel Corporation in the 1960's. The "Avenue", as it was then called, was sold to a developer in the 1970's. The first house was purchased in 1976. Today all the houses are individually owned and occupied.
Trevarno is a Welsh word meaning, "head of the valley." It was the name of William Bickford's home in Cornwall, England. Bickford invented the spun rope safety fuse manufactured by Coast.
The houses were built from 1913 to 1915 in the Arts and Crafts style of architecture, which emphasizes native building materials, fine craftsmanship, and harmony with nature. Practical elements include overhanging eaves to shade the summer sun and many windows to let in light and air. Part of the charm of Trevarno Road is the openness of the area. The residents work through the homeowner's association to preserve the ambience and community feeling of this historic district.
