The Mount Umunhum Summit project is an excellent reflection of Midpen's three-part mission statement: to preserve open space, to protect and restore the natural environment, and to provide opportunities for ecologically sensitive public enjoyment and education.
A Sneak Peek at a Much-loved Peak
Here's a preview of what you'll see at the top of Mount Umunhum.
Location and Background
Mt. Umunhum, is located in the 18,000-acre Sierra Azul Open Space Preserve. At 3,486 feet, it’s the fourth-highest peak in the Santa Cruz mountains and features spectacular 360-degree views that extend from the Monterey Peninsula to Mt. Tamalpais, and include much of the Bay Area and even the Sierra Nevada on a clear day. The word “Umunhum” means “resting place of the hummingbird”. The hummingbird is a central figure in the Amah Mutsun creation story. Including the hummingbird, this peak is home to 63 native plant and animal species. From 1957 to 1979, the summit was the site of the former Almaden Air Force Station where it served as part of a network of radar stations. The square concrete structure at the top of the peak served as the support for a large Cold War-era radar sail. The summit has been closed since 1980 when the base was decommissioned. In 2009, Midpen received federal funding to clean up the site. Midpen removed 3,000 cubic yards of hazardous materials, including lead paint, asbestos, fuel storage containers and PCB transformers, and deconstructed 13,680 tons on concrete, asphalt, wood and other materials, 97% of which were recycled or reused.
In the 1950s, the Air Force graded and flattened the summit of Mount Umunhum to provide room for an early warning radar station. Over the past few years the Midpeninsula Regional Open Space District has been working with experts to remove old buildings, lead, and asbestos and restore the summit to a more natural condition. The new summit will include new trails, viewing area, and habitat to welcome visitors, wildlife, and native plants back to the peak. Midpen plans to open the summit to the public in the fall of 2016 so that people can enjoy and experience a restored Mount Umunhum up close.
- The Bald Mountain Parking Area is open to the public.
- Planning for ecological restoration and visitor amenities at the summit is underway.
- Much of the summit has been recontoured and returned to its natural state.
- Restoration will focus on naturalizing the topography and restoring native habitat. The summit will be fully accessible to visitors of all abilities and will feature a ceremonial circle, view points, shaded picnic areas, and interpretive features and programs.
- The Mount Umunhum Trail and the associated bridges are currently under construction. The trail will connect the Bald Mountain Parking Area to the summit of Mount Umunhum, and is expected to open for public use no later than fall of 2016, or as soon as possible following construction and once facilities at the summit have been completed.
The primary goal of the Mount Umunhum Summit Project is to establish a visitor destination that balances public access, enjoyment, and education with environmental restoration. This aligns with two directives of Midpen's Mission: to protect and restore the natural environment, and to provide opportunities for ecologically-sensitive public enjoyment and education. This goal will be achieved through the following:
- Create a destination that is accessible to and accommodates a broad range of user groups and introduces new visitors to open space.
- Remove or permanently cap physical hazards and restore the native landscape and habitat for wildlife as much as possible.
- Provide minimal visitor amenities that complement and highlight the world-class views and open space experience.
- Provide ample, rich, and diverse trail experiences for hikers, bicyclists, and equestrians.
- Highlight the rich natural and cultural history of the site through self-discovery and focused interpretive and educational opportunities.
In the near term, providing public access to the summit of Mount Umunhum as soon as possible (target: fall of 2016) is a primary goal of this project. Once completed, visitors to the summit will find an ADA-accessible interpretive trail, information about the area’s rich natural and cultural history, and expansive views of the entire Bay Area, Monterey Bay, Santa Cruz, and even the Sierra Nevada.
Midpen’s vision has always been for Mount Umunhum to join the ranks of the Bay Area’s great publicly-accessible peaks: Mount Tamalpais, Mount Diablo and Mount Hamilton. To achieve that, Midpen spent three years researching potential options for the summit, listening to the public, and distilling that information into its 2012 plan that includes widening and repaving the 5-mile road, new parking and staging areas, gorgeous multi-use trails, a Native American ceremonial space, a spectacular overlook and three options for the “Cube,” the five-story concrete structure that once supported a radar sail when the former Almaden Air Force Station was active and is currently a prominent feature on the summit.
On August 26, 2015, the Board of Directors approved 7 - 0 the Final Design Development Options for the Mount Umunhum Summit Project, and directed District staff to look for areas for additional shade structures at the summit. These design development options DO NOT include recommendations for the Radar Tower. This decision allows staff to proceed with final design development and production of construction documents, which will form the basis for permit submittals and a Request for Bids package. Full details available in Board Report R-15-126.
Visitor amenities at the summit will include parking, ADA accessible pathways and trails, vault toilets, and multiple viewing coves featured across the west and east summit, providing visitors with a vantage point for world class views of the valley below.
In addition to public access, the Summit Project provides for the restoration of natural landforms, and planting of native vegetation.
Options for the Cube
OPTION 1: RESTORE THE MOUNTAINTOP
As much as possible, the summit of Mount Umunhum would be returned to its natural state. The Cube would be removed and recycled; and the land would be revegetated. The 2,000-square mile, 360-degree views from the summit would be completely unobstructed. Interpretive materials would share the summit’s important cultural, military and natural histories with the public.
Estimated construction costs: $640,000*
OPTION 2: OPEN AIR GATHERING PLACE
In this option, the summit would be returned to a more natural state, but a portion of the Cube walls and columns would be retained for an open air structure with interpretive materials that protects visitors from the high winds and, at times, glaring sun. Visitors would be able to enjoy the views and interpretive materials and would also be able to see, touch and experience the Cube and its interior walls.
Estimated construction costs: $817,000*
OPTION 3: SEAL AND RETAIN
In this option, with the participation of a partner, the Cube would be kept and sealed for public safety. Structural damage would be repaired and a new roof installed. The Cube would continue to be the most prominent feature at the summit and would occlude much of the view at this vista point. Interpretive materials would be provided along its exterior walls.
Estimated construction costs: $1,106,000*
*Based on 2012 cost estimates
In order to protect public safety and guarantee security, some portions of Sierra Azul's Mount Umunhum area are closed until the site is fully remediated and secure public access can be established.
Please note that the Mount Umunhum and Mount Thayer areas, where remediation work is ongoing, are designated Hazardous Closed Areas. Anyone who trespasses into the area will be cited for a misdemeanor.
Areas that are adjacent to Mount Umunhum and Mount Thayer are declared Temporary Closed Areas. Trespassers will be cited for an infraction. Please refer to the attached map for details.
|October 2017||Deadline for proponents of the Cube to establish and develop partnerships, funding, and other resources to allow for implementation of Option 3, Retain and Seal (per Interim Action).|
