Before the Spanish entrada, the Tamyen people mined the area for chert, which was typically used for debitage and arrow points. On November 29, 1777, Juan Bautista de Anza selected the area to become the southernmost region in the first land tract of the San Jose pueblo. Although similarly named, the area was not part of the neighboring Rancho San Juan BautistaMexican land grant. Located in the northern area of Communications Hill, Oak Hill Memorial Park, the oldest secular cemetery operating in California, performed its first recorded burial in 1847. Cinnabar is believed to have been discovered in the San Juan Bautista Hills in 1847 by a member of the Chaboya family. Soon afterwards, the Hillsdale Mine was established. However, operations were unsuccessful and the mine ceased operations in 1907. Tyler Beach purchased the Dairy Hill area in the late 1860s and named it Beach Hill Farm, which was used to supply the former St. James Hotel. On March 2, 1886, Southern Pacific incorporated the San Jose & Almaden Railroad to build the Lick Branch from Hillsdale 7.7 miles to Almaden. The branch was opened on November 16, 1866 and ran for several years. However, the line was shortened due to an abandonment in 1937. The remainder of the Lick Branch was formally abandoned in January of 1981. Between 1887 and 1890, the San Jose Vineyard operated in the area. In 1916, Manuel Azevedo and Manuel Lewis operated a dairy farm known as the American Dairy Company. The property was bounded by Stone Avenue to the north, Oak Hill Cemetery and Monterey Road to the east, the Almaden Road to the west and Hillsdale Avenue to the south. The Azevedo Quarry was actively mined by Raisch Products from 1971 to 2006. An aggregate recycling facility remains on the land, but it is also expected to shutdown in 2023 and be redeveloped into an office park when the county use permit expires. Starting in 1984, the Government of San Jose began preparing Communications Hill, then largely barren, for development into a mixed-use, high density, urban neighborhood. This was formalized with the creation of the Communications Hill Specific Plan in 1992. MTA Properties, a family trust owned by the descendants of Manuel Azevedo, began the process of residential development in 2002. Annexation of parcels to the city of San Jose has occurred as recently as December 9, 2014. The area is currently undergoing significant construction, which has been divided into four phases. A "village center" is planned, which will include shops and restaurants positioned to have a view of the Downtown San Jose skyline.
