1954 Map of Corona North

About this map

The Santa Ana River carves through the heart of this mid-century landscape, separating the agricultural plains of the north from the emerging residential and military sectors to the south. During this era, the region maintained a strong agrarian character, evidenced by the presence of the Fuller Ranch and Silver Lakes Ranch, even as military infrastructure like the Naval Reservation and its associated Hospital and Ordnance Laboratory established a firm federal footprint. The Prado Flood Control Basin dominates the western view, a critical piece of water management infrastructure for the growing Inland Empire.
