About this map

Covina and West Covina stand as established citrus-belt hubs in this survey conducted during the mid-1920s. The landscape is defined by the sharp contrast between the orderly grid of the San Jose Addition and the steep, complex terrain of the San Jose Hills. Early 20th-century institutional history is prominently marked by the Masonic Home and the Protestant Home For Boys, located along the fringes of the rising topography.

Transport and industry are dictated by the three major rail lines—the Pacific Electric, Southern Pacific, and Union Pacific—which funnel through the narrow corridor between the hills. In the southern portion of the map, the Diamond Bar Ranch and the small settlement of Spadra represent the rural holdings of eastern Los Angeles County before the era of intensive suburbanization, situated along the path of Walnut Creek and the San Jose Wash.
