The Patterson Ranch Company was a livestock, dairy, and agricultural farm originally located on the Oxnard plains, near Wooley and Patterson Roads. Peter Hartveld, an immigrant from Holland, was the ranch foreman and responsible for much of the day-to-day running of the ranch. The 5,000-acre ranch was named for New York farmer John D. Patterson who arrived in California in 1854, and in 1866 he purchased land from Rancho El Rio de Santa Clara, or La Colonia. Patterson never lived on the ranch, but hired managers to run the farm.
