2018 Map of Patterson

About this map

The city of Patterson serves as the focal point of this map, positioned at the edge of the San Joaquin Valley where the flat agricultural basin meets the rising terrain of the Diablo Range. The landscape is defined by massive water infrastructure, most notably the Governor Edmund G. Brown California Aqueduct and the Delta-Mendota Canal, which cut diagonally across the terrain to support the region's intensive irrigation. These engineering works parallel natural drainages like Del Puerto Cr and Salado Cr. Residential expansion is evident in the burgeoning street networks of southern Patterson, while the western portion of the sheet remains dominated by the steep topography of Del Puerto Canyon and Black Gulch. The complex system of irrigation, including the Hirshfield Lateral and Lateral Six S, illustrates the transformation of this arid environment into a productive agricultural hub.
