Welcome to the Conservancy

The Umunhum Conservancy is a non-profit corporation dedicated to the preservation and restoration of Mt. Umunhum and its historic Radar Tower.

The historic Radar Tower atop Mt. Umunhum will be demolished unless the Conservancy raises funds to preserve it.

Mt. Umunhum and the Radar Tower are owned by the Mid-Peninsula Regional Open Space District (MROSD).  MROSD is in the process of opening the summit of Mt. Umunhum to the public.  However, MROSD does not spend its funds on historic preservation.  Unless the Conservancy raises funds to save it, the Radar Tower will be demolished.

Support from Local Leaders

Numerous local political figures and other community leaders support preserving the Radar Tower atop Mt. Umunhum.  Check out the list, and thank them for their support!

Mid-Pen Open Space Bond Measure AA

The Mid-Peninsula Regional Open Space District placed Measure AA on the June 2014 ballot. The Measure authorized $300 million for various projects.  While several of those projects would be on or near Mt. Umunhum, none of the funds from the Bond Measure would go to preserve the Radar Tower.  See more details here.
