The Historical Heritage Commission (HHC) was established by the Board of Supervisors to protect, preserve, and promote historic resources within Santa Clara County. It is comprised of volunteer community representatives, with two commissioners representing each of the five County supervisorial districts and one member serving at-large.

The HHC ordinarily meets the third Thursday of each month at 6:30 PM in the Board of Supervisors Chambers.

Mt Umunhum

The Mt. Umunhum radar tower is the last remaining building of the former Almaden Air Force Station, located on Mt. Umunhum within the Sierra Azul Open Space Preserve. The radar tower has been nominated for listing on the County Heritage Resource Inventory.

The County has received two evaluations of the radar tower. One evaluation, provided by a historical consultant working for the Midpeninsula Regional Open Space District, concluded that the tower is not eligible for inclusion on the County’s Heritage Resource Inventory. The other evaluation, provided by a historical consultant working for the Umunhum Conservancy, concludes that it is eligible. The following third report, prepared by JRP Historical Consulting Inc. working under contract for the County Planning Office, provide a peer review of both previous evaluations, and provides a separate analysis regarding the eligibility of the tower for County listing.

On February 18, 2016, the Historical Heritage Commission will hold a public hearing to determine whether or not the Mt. Umunhum radar tower is eligible for listing on the County’s Heritage Resource Inventory, and will forward a recommendation to the Board of Supervisors. The public hearing will be held on:

Thursday, February 18, 2016 at 6:30 PM
