Honoring climate change makers across the bay
The federal government has spent the past year dismantling the very foundation of American climate policy. When the EPA revoked its longstanding finding that greenhouse gases threaten public health, it signaled that we can no longer count on Washington to protect our communities from the accelerating consequences of climate change.
But here’s what that shift has made undeniable: local action has never mattered more.
Now in its sixth year, this celebration has become a powerful platform for amplifying those stories — and for reminding us that progress is still being made, right here, right now.
Join us in Oakland for an end-of-summer bash as residents, nonprofits, government, and businesses come together to honor this year’s honorees and reaffirm our collective commitment to the Bay Area we’re building together.

Nature-Based Adaptation Awardee
Miguel Marquez
Miguel is a Park Ranger for the U.S. Fish and Wildlife Service at the San Francisco Bay National Wildlife Refuge Complex. He was the first in his family to graduate college, earning a BA in Environmental Studies with an option in Natural Resource Land Use Management from Cal State University Hayward in 2006.
Miguel connects with the surrounding community through outreach, education programs, volunteer clean-ups, and outdoor recreation. He often visits local schools to speak with students about his career path and the importance of wildlife conservation and habitat restoration. Before joining the U.S. Fish and Wildlife Service about five years ago, Miguel was a Park Ranger with the National Park Service in Washington DC, Hot Springs Arkansas, and San Francisco, serving as a park guide, supervisory park ranger, and interpretive specialist. Being an Interpretive Ranger allows him to share stories of the past, work at historical sites, lead hiking, biking, and kayak tours, and inspire, educate, and connect with people from within his community and abroad.
Miguel enjoys connecting and sharing his passion for wildlife with others and building future stewards of public lands. From the West Coast to the East, and down south and back to the Bay, he continues to promote environmental education, build community, and share his love for the outdoors.

Department City and County of San Francisco
“The through lane for my work as an artist, community organizer, sustainability manager, policymaker is the three pillars that I orient my life around: community, connection, and creativity. I'm very much driven by that dedication to the broader good.”
“Having housing near jobs and reducing people's commute patterns and GHG emissions is positive for the climate. But what always excites me is it's actually positive for people's lives.”
“Part of prevention is changing someone's behavior. It isn't always about telling someone what they need to do. It is, how can someone do their part to be part of the solution.”
"People look to the Bay Area and to California as a place of innovation. We have the ability to pilot things to learn from that can be replicated elsewhere. I'm excited about the problem we have to solve but also the level of ingenuity and innovation when we bring nature into the recipe to develop our way forward."
"The whole idea of restoring watersheds—we started in that 30 years ago for the sake of nature, but now it’s nature-based solutions for the sake of climate change."
"Affordable housing along with sustainability go hand in hand. Building permanently affordable housing has been right up there as an agenda in (East Palo Alto) since the get-go. It's great to always live, work, and play in the same place."
“It’s critically important to focus on what we're leaving behind and the state that we're leaving it in. We have a responsibility to conserve land, community character, and a functional way of life for future generations.”
“The decision to preserve Coyote Valley was the last opportunity to say let's not continue with the sprawl from the 60s, 70s, 80s, and let's preserve what really was the last part of Santa Clara County and the valley that was agriculture and open space.”
“When you're looking at land use and transportation and how these interact with each other, if you layer on gender and race, you can see how they intersect with each other and then add on climate. Climate SMART housing is not just about designing a house or a building that's climate-smart. It has to be interconnected.”
Hidden Heroes of the Greenbelt is an annual benefit for Greenbelt Alliance that honors the often unseen yet remarkable government staff leading extraordinary work at the intersection of land use and climate change in the Bay Area.
Throughout our 65+ year history, we’ve worked alongside dedicated government staff catalyzing impact in their communities across the Bay Area. Many of these heroes are creating systemic change for our cities by taking on complex projects to increase housing opportunities while protecting nature, expanding outdoor access, and building climate resilience. From launching parklet plans during the pandemic to facilitating wildfire education and building living levees, these local climate champions are creating lasting change.
The Hidden Heroes of the Greenbelt event is a festive day when residents, nonprofits, government, and businesses come together and celebrate our collective commitment to this work. Over four years, this celebration has become a powerful platform amplifying the inspiring stories of those who transform how our region addresses its pressing environmental challenges.
