A section of the land was sold in 1907 by the Yorba family to Fullerton businessman Jacob Stern, who used the land for barley fields and sheep grazing. Stern subsequently sold the tract to the Janss Investment Company, which first called the area Yorba Linda, and proceeded to subdivide the land and sell it for agriculture and manufacturing. In 1910, the agricultural aspect of that endeavor materialized, and the first of many lemon and orange groves were planted: at the time, the population was still less than 50. A year later, The Pacific Telephone & Telegraph Company began serving Yorba Linda, and the first school was constructed.
