1947 Map of Tranquillity

About this map

Tranquillity and Mendota anchor this post-war landscape in the San Joaquin Valley, where the natural water systems of Fresno Slough were being heavily managed for agriculture. The map captures an era of expanding irrigation and systematic land division, evidenced by the dense grid of avenues including Washington Avenue and James Avenue that structure the valley floor. The Southern Pacific railroad cuts a diagonal line across the terrain, connecting the small siding of Ingle to the larger regional hubs. The presence of the Herminghaus Ranch and the Fresno Slough Bypass highlights the transition from traditional ranching to engineered water control. Large tracts are defined by these surveyed roads and sloughs, showing how the Central Valley's topography was being reshaped into one of the most productive farming districts in California during the late 1940s.
