1942 Map of Santa Ana

About this map

The Santa Ana region during the early 1940s reveals an intricate coastal and agricultural landscape before the massive suburban expansion of later decades. The Santa Ana River cuts through a grid of developing towns and specialized agricultural districts, where small settlements like Greenville, Sugar, and Delhi are interspersed with active rail lines. The Southern Pacific and Atchison Topeka and Santa Fe railroads provide the backbone for local commerce, connecting the inland citrus and bean fields to the coast. Along the shoreline, Newport Beach, Balboa, and Huntington Beach appear as distinct coastal hubs, while the elevations of the San Joaquin Hills rise sharply to the southeast. Unique features like the Twenty Ranch Gun Club and Airway 39 highlight the era's land use, from private sporting grounds to early aviation infrastructure.
