History
The town began in 1905 with the founding of a large sugar beet processing plant, completed the following year by James Hamilton and the Alta California Sugar Beet Company (which changed its name in 1908 to Sacramento Valley Sugar Company). The plant later belonged to Holly Sugar Corporation and is known to this day as the Holly Sugar Plant. Holly Sugar was sold in 1936 to Spreckels Sugar Company and, in turn, Spreckels was later purchased by Imperial Sugar. The sugar plant closed in 2006, and in 2021 was acquired and renovated by Nutrien Company, a fertilizer producer.
