Early California central valley settlers saw their beginnings centered around farming. Wheat was the main crop in the early days due to a lack of rain in summers. In the early 1900s, Manteca got its start when farmland was inexpensive and new irrigation methods, Historya railway, and river-system all created promise for growing multiple crops and getting them to market. A farming boom started, with almonds, alfalfa, grapes, pumpkins, walnuts and more. Dairy operations also became reality. Many would begin to prosper with availability of SSJID irrigation water in 1913.

Now, as the area’s growing farm population created a demand for more services, the village of Manteca began attracting new residents and businesses. By 1918 the town incorporated, and companies, large and small, began to discover Manteca.
