1941 Map of Prado

About this map

The Santa Ana River carves a critical path through this landscape, meeting the confluence of Chino Creek and Mill Creek near the settlement of Prado. This pre-war survey illustrates a region defined by its water management and transit infrastructure, including the Atchison Canal and Imperial Canal alongside the Atchison Topeka and Santa Fe Railway. To the north, the City of Chino expands through a rigid grid of avenues like Edison Avenue and Merrill Avenue, while the foothills of the Puente Hills remain dominated by agricultural and recreational interests such as Pelissier Ranch and the Los Serranos Country Club. Local educational history is anchored by the Junior Republic School and Pioneer Sch, providing a detailed record of the community's early social foundations before the major suburban shifts of the mid-20th century.
