Its foundation was directly linked to the Sunnyside Canal, a major irrigation project that transformed arid land into productive agricultural tracts, attracting settlers seeking economic opportunity in farming. The presence of early automobiles and unpaved roads indicates a period of development likely in the 1900s or 1910s, reflecting the town's nascent stage.
