David Greenawalt Farm, 14611 Almaden Expressway, San Jose, Santa Clara County, CA

Significance: The 19th century tank house is an architectural artifact that was once commonplace throughout the Santa Clara Valley, providing a constant supply of large volumes of water to fruit crops and the main house. As a result of more modernized irrigation systems, the tank house - a structure that was significant in the development of the fruit-growing industry during the 1870s in this area - is obsolete to large operations today, and is consequently vanishing from the county. The square, two-story frame structure built by David Greenawalt ca. 1877, covered with shiplap siding and trimmed at door and window openings and the roof eave to complement the main house's stylistic design, is a good example of many that filled the landscape in the second half of the 19th century.
