History
Knightsen is a small, unincorporated community of 1,568 residents and 1,500 horses in far eastern Contra Costa County, California in the eastern San Francisco Bay Area closest to Oakley, California. The community was founded by George W. Knight, and its name is a portmanteau of his last name and his wife (Christina Christensen). Knightsen has the oldest chapter of the 4-H Club in California. The community worries about urban sprawl from expanding development in neighboring Oakley. However, a significant portion of the community lies within the agricultural conservation zone in the Brentwood, general plan.
During the 1880s, settlers began moving in and planting the first almond trees in the area. A few dairies also sprang up. Other crops, such as apricots, grapes and alfalfa were also planted. Until the railroad was built, farmers shipped their produce via water, using Babbes Landing off Dutch Slough, near the north end of what is now Sellers Avenue.
