In 2002 the City of San José, in partnership with Santa Clara County Parks and Recreation, used a $900,000 grant from the Open Space Authority to purchase property to expand Santa Teresa County Park Historic Area. The 1.93-acre parcel adjoins the historic Bernal-Gulnac-Joice Ranch interpretive site and Santa Teresa Springs. The ranch buildings and surrounding 28-acre property are what remains of a nearly 10,000-acre tract granted to Jose Joaquin Bernal by the Mexican government in 1834.
