11 Historic Integrity The California Register regulations define "integrity" as "the authenticity of a property's physical identity, evidenced by the survival of characteristics that existed during the property's period of significance." That is, a property must retain enough of its historic character or appearance to be recognizable as an historical resource. The “period of significance” has to date from fifty years ago or more. California Register regulations specify that integrity is a quality that applies to historic resources in seven ways: location, design, setting, materials, workmanship, feeling and association. A property must retain most of these qualities to possess integrity. The two houses at 11021 and 11033 Dublin Canyon Road retain a good level of historic integrity. The exterior and interiors of both houses retain integrity of design and materials from their original construction. The historic integrity of the Bungalow house at 11021 Dublin Canyon Road has been somewhat compromised because of its poor condition, which includes its sloping roof and the front porch tilting away from the house. This visual evidence of the house’s condition may indicate serious structural deficiencies. The Terra Ranch does not retain historic integrity as a ranch complex since none of the original barns and outbuildings associated with the property’s earlier use as a cattle and dairy ranch survive. The ranch lacks integrity of design, materials, feeling and association. The Four Criteria of Significance Criterion 1: The resource is associated with events or patterns of events that have made a significant contribution to the broad patterns of local and regional history. The house at 11021 Dublin Canyon Road is associated with cultural patterns such as ranching or agricultural history of the Dublin/Pleasanton. However the property is not eligible under California Register criterion 1 because of the loss of all the original barns and outbuildings associated with its original use as a ranch. The historic integrity as a ranch has been compromised. The house at 11033 Dublin Canyon Road is a suburban Ranch house not associated with the property’s use as a ranch. In conclusion, the houses at 11021-11033 Dublin Canyon Road do not appear to be historically significant because of its association with local history, thus the houses are not significant under California Register Criterion 1. Criterion 2: The resource is associated with the lives of persons important to the nation or to California's past. Historic research did not identify any significant persons in local history who had lived in the houses at 11021 and 11033 Dublin Canyon Road, thus the houses do not appear to be significant under California Register Criterion 2. The earliest occupants of the house at 11021 Dublin Canyon Road, Mary and Joseph Fernandes, a farmer, was not a significant person in local history. Beginning in circa 1940, Manuel Terra, Sr., followed by his son Manuel Terra, Jr., occupied 11021 Dublin Canyon Road. They were typical ranchers in the Dublin area and not
