Industrial expansion defines the landscape of Maricopa during the early 1940s, as the War Department and Corps of Engineers documented this vital oil-producing region. The map reveals an intricate network of energy infrastructure, including the Norwalk Oil Co Refinery, Standard Oil Gas Plant No 31 E, and multiple Oil Sump sites. This concentration of industrial activity is supported by a robust transportation and utility grid, notably the Sunset Railway and lines belonging to Pacific Gas and Electric Co.
