Du Bois Ranch Airport

The closure was due to the cessation of private aviation activities. As a private agricultural airstrip, its existence was tied to the needs of the ranch owner. The land was subsequently repurposed for its primary and more economically valuable use: agriculture. There is no evidence of military conversion or a specific accident causing the closure.

The site has been completely reclaimed for agricultural purposes. Satellite imagery of the coordinates shows the land is now occupied by an orchard or vineyard, with no visible remnants of the former runway, taxiways, or any airport-related structures. The land is indistinguishable from the surrounding farmland.

Du Bois Ranch Airport was a private airstrip, characteristic of many small airfields that supported California's agricultural industry in the mid-to-late 20th century. Its primary function was likely to support the operations of the Du Bois Ranch, including agricultural aviation (crop dusting), personal transportation for the owner, and other farm-related business. It featured a single, unpaved 2,600-foot runway and had no significant public or commercial operations. Its significance lies in being a typical example of a private 'ag strip' from that era.

There are no known plans or prospects for reopening the Du Bois Ranch Airport. The land has been fully converted to high-value agricultural use, which would make re-establishing an airport economically unfeasible. The airport holds no strategic or public importance that would warrant such an effort.
