Standard developed an indoor mall at the site, with the mall opening in 1975. In 1976, a library was opened in the community, and in 1990 the city of Hillsboro took over those operations and maintained the branch until 2007, when it was closed and a new main branch of the Hillsboro Public Library was opened farther west. In 1983, the county approved a master plan created by Standard to develop at Tanasbourne. Hillsboro annexed much of the Tanasbourne area in 1987. The next year plans were announced for an expansion of the old mall along with construction of new retail buildings in the area. The mall was never expanded.
