1974 Map of Tustin

About this map

Orange County land use undergoes a massive transition in this 1974 orthophotoquad, which captures the shifting patterns of agriculture and suburban development. The aerial imagery reveals an intricate patchwork of commercial orchards and large-scale agricultural plots as they yield to the expanding residential footprint of Newport Beach and the surrounding plains. The Orange County Board of Supervisors and the U.S. Geological Survey collaborated on this study, documenting the region's precise layout of early master-planned communities, winding suburban streets, and the industrial structures of the time. This visual record provides an unmatched perspective on the spatial history of the county, showing exactly which groves remained and which hillside developments were just beginning to take shape in the mid-1970s.
