About this map

The Prado Dam and the expansive Prado Flood Control Basin dominate this mid-century landscape where the Santa Ana River meets a network of drainage canals and industrial activity. To the north, the sprawling grounds of the California Institution for Men sit adjacent to several institutional and educational landmarks, including the Junior Republic School and the Casa Colinda Crippled Childrens Home. This era represents a significant transition for the region, noted by the presence of the Cal-Aero Flight Academy (Deactivated) and the Cal-Aero Primary Sch, reflecting the area's role in aviation training during and immediately after the war. Southward, the residential and recreational pockets of Los Serranos and the Los Serranos Country Club are carved into the hills. The map also records early water management and resource extraction through features like the Santa Ana Valley Canal and scattered Gravel Pit operations.
