Felta School was built near the confluence of Felta Creek and Mill Creek and named for Felta Miller, an early settler, who homesteaded his ranch about a mile up Felta Creek, and the green barn at the end of the county road that passed the school site was generally accepted as the original mill that Mill Creek was named for. It is believed to date from the Mexican era. Harmon Heald, a hand who worked in the mill, opened a store at a nearby crossroads, and began the town of Healdsburg. J.G. Mothorn, who founded Mill Stone Valley Ranch, on which the barn still stands, had portions of his property landscaped by his friend, Luther Burbank. Some of Burbank’s plantings, which included guavas, loquats, grafted plums, and a lily tree, survive unto the present day. Mothorn’s son used stones from a cobblestone quarry on the Mothorn ranch to build the foundation of Felta School. The school, while under construction, survived the 1906 earthquake.

On November 27, 1951, residents of the area west of the Russian River near Healdsburg voted to close their five one-room Sonoma County rural schools -- Felta, Daniels,Junction, Lafayette and Mill Creek. The 85 students from the former districts began the 1956-1957 school year at the new West Side Union School, located a short distance from the old Felta School.

Felta School has since been restored and is located at 1034 Felta Road, Healdsburg, California.
