Nature-Based Solutions in San Diego

Nature-based solutions are actions to help protect, sustainably manage and restore natural or modified ecosystems that address societal challenges while simultaneously providing benefits for people and the environment. As the most biodiverse county in the continental United States, San Diego County is well positioned to utilize nature-based solutions. These actions can help reduce greenhouse gas emissions and achieve societal co-benefits.

Nature-based solutions aim to enhance the natural function of ecosystems to provide multiple societal co-benefits such as improved public health through cleaner air and water as well as the availability of open space, improvements to habitat for wildlife and plants, flood risk reduction and other ecosystem services that enhance the resiliency of our environment. Natural and working lands are vital in the carbon cycle in San Diego and throughout California. Healthy ecosystems that include vegetation and soil microbes capture and store carbon from the atmosphere. In contrast, changes that alter or damage ecosystems, including land use modifications, deforestation and wildfires, can release sequestered carbon back into the atmosphere, accelerating the climate crisis. To balance between carbon stored and carbon released determines whether natural lands and ecosystems function as net sources or net carbon sinks. Protection of natural environments from land use and disturbances helps promote the functioning of forests, wetlands and oceans as carbon sinks that absorb more carbon than they emit.

San Diego has initiated multiple nature-based solutions projects already. However, the need to develop and scale up these projects is ever increasing as San Diego and California face impacts of the climate crisis. The United States Economic Development Administration’s Economic Integrator helped catalyze a nature-based solution project focused on upstream improvements to reduce runoff and debris deposited into San Diego’s stormwater infrastructure. This project helps mitigate the impact of flooding in the urban center while enhancing outdoor recreation and economic development for the County. The project focuses on Maple Canyon, nestled between Balboa Park and San Diego International Airport, a green space that buffers business with nature inside the urban core of San Diego. As flooding during storm events occurs, runoff and debris impact the downstream commercial enterprises, transportation networks and natural habitats. Restoration efforts have minimized flooding and stormwater runoff, helping protect vital urban infrastructure and important urban and natural landscapes.

As a coastal city, enhancing the resiliency of our coast is vital to managing climate change impacts such as sea level rise, coastal erosion and storm surges. Coastal wetlands throughout San Diego County are essential ecosystems that not only help with flood protection but are also some of the most productive ecosystems that play an integral role in the ecology of our watershed. Coastal wetlands are also considered “blue carbon ecosystems,” which include habitats like salt marshes and seagrass meadows that help capture and store more atmospheric carbon per acre than terrestrial forests. Nature-based solutions that preserve and restore these wetlands help build community resilience to the impacts of climate change by sequestering carbon and helping enhance the resiliency to sea level rise and coastal flooding. The Blue Carbon Collaborative, founded by the nonprofit organization Wildcoast, is a network of organizations working on the conservation, research and policy developments for blue carbon ecosystems and nature-based solutions. 

Only 10 percent of California’s original wetlands remain, yet they are some of the best ecosystems on the planet for taking carbon out of the atmosphere and storing it in the ground for a long time. Restoration of these wetlands provides an opportunity to enhance these ecosystems' production and utilize their potential as a natural climate solution. Aligning nature based solutions with the 30x30 plan to conserve 30 percent of our land and coastal waters by 2030 to protect biodiversity will expand access to nature while lessening the impacts of the climate crisis.

Freedom Takes Root

Reflecting on Juneteenth, environmental justice and our shared responsibility to cultivate the conditions for life to thrive

“Even though the story has never been tidy, and Black folks have had to march and fight for every inch of our freedom, our story is nonetheless one of progress,” said Michelle Obama.

Today, we celebrate Juneteenth—the day in 1865 when the last enslaved Black Americans in Galveston, Texas learned they were free, more than two years after the Emancipation Proclamation had been signed. It is a day of remembrance, resilience, and unfinished work. A reminder that freedom delayed is freedom denied—and that liberation is something each generation is called to carry forward.

As we reflect today, we're invited to ask a deeper question: 

What does it truly mean to be free?

Perhaps freedom isn't only what we're liberated from.

Perhaps it's also what we're free to become.

To breathe deeply.

To drink clean water.

To take root.

To belong unapologetically.

To know that the place we call home has everything needed to sustain life—not only for ourselves, but for the countless beings with whom we share it.

Our lives are shaped by what's in the air.

By the water flowing through, around and beneath.

By the health of our soil and its smallest helpers.

By the canopies of our trees and all they shelter.

By the pollinators, fungi, oceans, rivers, and relationships—both human and more-than-human—that quietly make life possible every single day.

Liberation lives not only in our laws, but in our landscapes.

It lives in neighborhoods where children can safely play outside.

In rivers that run clean.

In forests of emerald green.

In communities resilient enough to weather storms together.

In the places we call home.

Because we have never existed apart from the living world.

When communities are burdened by pollution, chronic disinvestment or climate disasters, ecosystems suffer alongside them.

When forests disappear, waters are contaminated, species vanish, or soils are exhausted, people suffer too.

Our futures have always been intertwined.

Environmental justice reminds us that caring for people and caring for the Earth are not separate acts.

They are one and the same.

At Hammond Climate Solutions Foundation, we believe thriving is never the result of just one thing.

Healthy communities are built when clean energy, healthy ecosystems, affordable homes, public health, youth leadership, reliable transportation and strong relationships are woven together.

Because liberation is not simply the absence of injustice.

It is the presence of the conditions that allow life—in all its forms—to flourish.

This Juneteenth, may we honor those who fought for freedom by continuing to build a future where every person, every community, and every living being has the opportunity not only to survive, but to flourish and thrive.

Together. Ashe.

Community Members and Elected Officials Celebrate Clean Energy Resilience Project at Boys & Girls Clubs of South County's Imperial Beach Club

The new clean energy system will generate nearly half a million dollars in savings, strengthen emergency preparedness and support healthier futures for local youth and families.

Community leaders, elected officials, youth, labor partners, funders and local residents gathered Wednesday at the Boys & Girls Clubs of South County's Imperial Beach Club to celebrate the completion of a clean energy resilience project designed to strengthen community preparedness, reduce operating costs and create a healthier future for Imperial Beach families.

The project, a 25.5-kilowatt solar energy system paired with a 54-kilowatt-hour battery storage system, was installed by Aloha Solar Power, an International Brotherhood of Electrical Workers Local 569 union contractor, and made possible through a collaborative effort led by Hammond Climate Solutions Foundation and its partners. The system will help the Club continue serving youth and families during emergencies and power outages while strengthening community resilience and preparedness. The Club is expected to save approximately $12,000 in utility bills in its first year and more than $465,000 over the next 30 years, creating long-term financial benefits that will be reinvested into youth programs and services. 

"For many families, the Boys & Girls Club is much more than an after-school program — it's a safe and trusted space where young people learn, grow and build community," said Stephanie James,  chief executive director of the Boys & Girls Clubs of South County. "This investment strengthens our ability to support the children and families who rely on us every day while helping us prepare for whatever challenges the future may bring."

While Imperial Beach continues to face environmental challenges that have drawn regional, statewide and national attention, the event highlighted a different story — one of investment, partnership, dedication, community resilience and hope for a healthier future. Project partners celebrated a transformative investment that will create healthier environments, expand educational opportunities and strengthen long-term resilience for local youth and families.

"Today's ribbon cutting is about more than clean energy. It is about ensuring that this club can continue serving young people and families when they need it most," said Supervisor Paloma Aguirre, who represents District 1 on the San Diego County Board of Supervisors and previously served as mayor of Imperial Beach. "It also represents a commitment to environmental justice. Communities that have experienced the greatest environmental impacts should be among the first to benefit from clean energy investments and modern infrastructure, but we know that that is not always the case."

The project also creates opportunities for hands-on learning and workforce development, helping introduce young people to clean energy technologies and potential career pathways in sustainability and the skilled trades. Following the ribbon-cutting ceremony, Club youth participated in a hands-on solar oven demonstration led by Jim La Joie, inventor of the All Season Solar Cooker and founder of SolCook. The demonstration introduced youth to solar energy principles, solar cooking, and career opportunities in clean energy and sustainability.

While the ribbon-cutting marked the completion of the solar and battery project, partners emphasized that it also serves as a foundation for future investments in health, education and resilience that will benefit youth and families in Imperial Beach and beyond.

"While the ribbon-cutting marks the completion of an important project, the opportunities created by this investment extend far beyond today's celebration," said Tara Hammond, founder and executive director of Hammond Climate Solutions Foundation. "Through our Holistic Healthy Communities Pilot Program at the Club, we look forward to building on this foundation by advancing healthier indoor and outdoor environments, expanding climate education opportunities and helping create an even stronger, healthier and more resilient future for the youth and families served here."

The Boys & Girls Clubs of South County's clean energy resilience project was made possible through a collaborative effort involving Hammond Climate Solutions Foundation, BQuest Foundation, Aloha Solar Power, IBEW Local 569, San Diego Community Power in partnership with the San Diego Foundation and Calpine Community Energy, along with philanthropic partners, donors and community members committed to advancing equitable climate solutions in the South Bay.

Oceanside Greenhouse Gas Reduction Program Continues to Deliver Climate and Community Benefits

The Oceanside Greenhouse Gas Reduction Program is delivering measurable progress by advancing clean energy, reducing greenhouse gas emissions and investing in community-serving organizations across the city.

Oceanside, CA  — The Oceanside Greenhouse Gas Reduction Program is delivering measurable progress by advancing clean energy, reducing greenhouse gas emissions and investing in community-serving organizations across the city.

Launched in September 2025, the current phase  of the program is already nearing completion on multiple projects just six months in. Funded by Preserve Calavera in partnership with the San Diego Foundation and managed by Hammond Climate Solutions Foundation, the initiative is part of a broader effort to strengthen local climate action, build community resilience and advance equitable climate solutions. Funded projects include solar and battery installations for nonprofit facilities and low-income households, along with expanded food recovery efforts that reduce waste and emissions while increasing access to fresh, healthy food. 

At the Boys & Girls Clubs of Northwest San Diego’s Oceanside Clubhouse, critical pre-installation improvements have been completed, preparing the site for a solar and storage system that will reduce long-term electricity use and allow the organization to reinvest savings into youth programs. Investments in youth-serving organizations are also creating long-term community benefits and supporting local union jobs. “This gift is about so much more than solar panels. It’s an investment in our community, our future, and the young people who walk through our doors every day. By reducing our energy costs, we can direct more resources where they have the greatest impact supporting youth,” said Marineke Vandervort, CEO. 

Similarly, the North County Alano Club has begun installation of a solar and battery system that will significantly lower operating costs and emissions.

“Since the 1960s, the North County Alano Club has been helping alcoholics and other addicts recover from a seemingly hopeless state of mind and body — serving an average 4,000 people each month in 2025,” said Dan McSwain, a representative from the organization. “We rely 100% on donations, usually $1 at a time, and operate on a very tight budget. The result of this grant is reducing our overall expenses by 25 percent, allowing us to not only survive but thrive for decades to come.”

In addition to clean energy projects, the program is advancing climate and food equity through ProduceGood’s CropCircle Collective initiative, which has already recovered nearly 3,000 pounds of produce and is scaling operations across Oceanside.

“ProduceGood is focused on climate and social equity. Through the generous support of the Greenhouse Gas Reduction Program, the organization will increase food recovery by 100% in Oceanside while increasing access to fresh produce for hundreds of families.”

The program also expanded access to clean energy for low-income households. A few lucky families were able to have no-cost solar and battery systems installed in Oceanside’s Communities of Concern. These installations are expected to deliver more than 24 metric tons of annual greenhouse gas reductions while lowering energy bills and providing backup power during outages.

“Through the Oceanside Greenhouse Gas Reduction Program, this funding enables the delivery of no-cost solar plus battery systems to Oceanside households, directly reducing local emissions while strengthening community resilience,” said Ben Airth, Policy Director at Freedom Forever. “By keeping climate dollars in the community, the program helps lower electric bills and ensures families can maintain power when the grid is stressed. We are honored to work alongside Preserve Calavera and Hammond Climate Solutions Foundation to make these projects possible and hope this success paves the way for similar climate investments in other cities.”

These projects demonstrate how targeted, community-based climate investments can reduce emissions, lower costs, lessen stress on California’s aging electrical grid, offer energy resilience and deliver meaningful benefits to the community.

Additional announcements are expected as projects reach completion and further impacts are realized.
