Restoration of Mt. Tamalpais’ West Peak Underway


The tallest of Mt. Tamalpais’ three pinnacles, West Peak was leveled in the 1950s to create an Air Force base to defend San Francisco against a Cold War nuclear attack. The military eventually closed the base in the 1980s, leaving just under 10 acres of concrete, buildings, power lines, metal fences, pipes, and other infrastructure within the peak’s sweeping 360-degree views and rare serpentine habitats. 

Thanks to a newly updated site analysis and renewed community engagement, that may all change. 

For the past year, a team of engineers, landscape architects, geologists, biologists, and community scientists have been researching, sampling, surveying, and analyzing Mt. Tam’s West Peak to envision what the future of this unique and little-known site might look like.

This restoration feasibility study—supported by $450,000 of philanthropic funds raised by the Marin Municipal Water District (MMWD) and the Golden Gate National Parks Conservancy—is the first comprehensive look at the site’s contamination levels, safety hazards, past soil movement and land disturbance, surface and groundwater flow patterns, habitat restoration options and remaining historic resources. 

At the same time, a series of public walks and an online survey have provided community members a way to learn more about West Peak and share their vision for its future. 

Parks Conservancy Project Manager Claire Mooney notes, “We’ve been working with a talented team of MMWD and Parks Conservancy staff, as well as folks that worked on a very similar project on Mt. Umunhum for the Midpeninsula Regional Open Space District. Thanks to their efforts we now have a tremendous amount of site-specific information to bring to bear on defining a set of restoration concepts for West Peak.”

As the agency responsible for managing West Peak, MMWD will be the first to review and provide direction on the range of possible restoration options at their September 21st Watershed Committee meeting. The vetted restoration concepts will then be shared with the public from 5 – 8pm on October 5th at “From Base to Peak: An evening of exploration and discussion about the future of Mt. Tamalpais’ West Peak” being hosted by MMWD and One Tam at the Mill Valley Community Center.

Rather than a fixed set of ideas to choose from, the restoration options presented on October 5th will include a suite of scenarios for habitat restoration and public access. Members of the public will have the opportunity to weigh in on each of these aspects to help shape where on the spectrum of alternatives the project lands. 

“Community engagement is vital and will inform a preferred restoration concept,” says MMWD Board Member Armando Quintero. “Even if you aren’t familiar with West Peak, there will be ample opportunities to learn more on October 5th, and we welcome and encourage anyone who loves Mt. Tam to come and be a part of shaping the future of this truly special place.” 

The evening will include an interactive exhibit on West Peak’s history and the proposed restoration effort, and offer opportunities to ask questions and leave comments. Presentations from a small panel of project managers and community members will share key details about the feasibility study, restoration alternatives, and the importance of this project to Mt. Tam and its community of supporters, past, present, and future.

As a member of the One Tam LINC summer high school program said when visiting West Peak for the first time, “I like the amazing view and the fact that it’s a place to get away from society. It’s also very quiet, which is nice. It gives me an opportunity to reflect on my own thoughts.”

For those who can’t make it on October 5th, the exhibit will be on display in the Mill Valley Community Center’s lobby beginning October 2nd. Comments are also welcome at through the end of October. This website provides more information about the project, meetings, technical study findings and the development of restoration alternatives. 

All of the community feedback received on October 5th and through the online survey will be considered in the development of the restoration alternative that will ultimately be selected by MMWD. Project managers are aiming to have a preferred alternative to present to the MMWD Board of Directors by the end of the year. 

The restoration of West Peak effort relies on the generous support from the community, and with the help of dedicated volunteers.
