New Street Tree Nursery Creates
an Urban Oasis

Construction on San Francisco’s new street tree nursery began this past June with a muscular shovel scoop of soil to break ground on a barren South of Market lot and culminated this month with a joyous celebration marking the opening of the transformative project.

State officials hold a press conference at the future tree nursery site in February 2022 to announce new Clean California grant-funded projects.

Construction of the transformative project moved quickly. But the idea for a public tree nursery in the heart of San Francisco emerged eight years ago as a recommendation in a government planning document. Turning that concept into reality, however, wasn’t easy.


When the Bureau of Urban Forestry's Jon Swae first started bringing early funders of the project to the proposed site, his vision of turning the patch of dirt and weeds next to roaring freeways ramps into a vibrant home for young trees and saplings was met with puzzled looks and skepticism.

Jon Swae, the Bureau of Urban Forestry grants manager, helped shepherd the project.

“You could see they were uncomfortable; in their faces, they had these uncertain looks,” said Swae, the Bureau of Urban Forestry grants manager who shepherded the project. “To which I replied, ‘Can you see it?’ They’d be like, ‘Maybe?’”


Despite the early reticence, the $6.5 million street tree nursery – the first of its kind in San Francisco – took root.

Freeway ramps and the San Francisco skyline frame the street tree nursery.

Located on Fifth Street, between Harrison and Bryant streets, and flanked by highway ramps near the western foot of the Bay Bridge, the budding street tree nursery provides space to grow up to 1,000 young trees at any given time. Once they grow big enough, they’ll be planted throughout the City’s neighborhoods – especially those lacking shade and plagued by polluted air.


The nursery is envisioned to deliver a locally based system of tree propagation and care, volunteer and educational programming and workforce development opportunities in the fields of urban forestry, environmental justice and climate protection. It will complement the Public Works StreetTreeSF program, which is responsible for the care of the City’s 125,000 street trees.

Public Works crews install native plants at the nursery.

“No one could’ve loved this land like Public Works,” said Swae who co-wrote the City’s Urban Forest Plan, which first proposed the nursery concept in 2015.

 

“It was such a challenging project and site. No other city or state department has quite the range of skills, talent and dedication required to transform this long-forgotten piece of San Francisco into a shining example of how community can come together to show that it’s possible to fight for the rebirth of San Francisco.”


The transformative effects of the 14,000-square-foot nursery are already noticeable. Where pigeons and rats used to rule the roost, pollinators – including hummingbirds, butterflies and California carpenter bees – are beginning to show up to stake their claim. 


A key benefit of the nursery is that tree species can be cultivated there that will fare better in San Francisco’s diverse microclimates. They include the California Buckeye, the Western Sycamore, the Coast Live Oak, the Ginko Tree, the Catalina Ironwood and the Strawberry Tree.

Clockwise from top right: California Buckeye, Ginko and Coast Live Oak are among the tree species that will be grown at the nursery.

The nursery’s slogan, “Justice, Jobs, Climate, Trees,” was carefully honed after considering not only San Francisco’s small tree canopy – 13.7% versus the national average of 27% – but also the need in underserved communities for meaningful work in local ecological restoration. Community members will be welcomed to the space to learn about urban forestry, environmental justice and climate protection.


Three former shipping containers – redesigned by UrbanBloc, a San Leandro-based firm that creates modular buildings from repurposed shipping containers – offer classroom space, an office and a breakroom for tree nursery volunteers and workforce development crews. Their job: Tend to saplings and young trees at the nursery until they are big enough to be planted in San Francisco’s low-canopy neighborhoods.

Native plants add life and beauty to the nursery grounds.

The street tree nursery will benefit people and ecosystems in San Francisco neighborhoods with the lowest tree canopy, communities that often bear the brunt of pollution from nearby industry or traffic-choked freeways and have less open space and greenery than others. 
 

“Scientific studies continue to show a strong correlation between greenery and race and greenery and socioeconomic status,” Jonathan Cordero, founder and executive director of the Association of Ramaytush Ohlone, told the crowd of elected officials, Public Works staff, community members and supporters during the nursery’s Nov. 9 ribbon cutting. 
 

“We know that being with nature has a positive impact on one’s physical, mental, emotional and spiritual health,” he said. “The street tree nursery makes a significant contribution to addressing these kinds of ecological injustices present in the City of San Francisco.”
 

The nursery project carries forward the ecological and social justice work of the Ramaytush Ohlone, the original peoples of the San Francisco Peninsula, said Cordero, as he stood in front of a small forest of more than 100 young trees growing in 15-gallon pots. 

“As native peoples, our primary responsibilities are to care for the natural world, and to care for the people who reside in our ancestral homeland, especially marginalized communities,” he said. “Any project at the intersection of ecology and equity counts as a high priority for us, and so it was easy to offer our unwavering support for this project.”
 

Working with its nonprofit grant partner, Friends of the Urban Forest, the Public Works street tree nursery will house the “New Roots” workforce development program, which will draw participants from the Bayview-Hunters Point, South of Market and Tenderloin neighborhoods for training in arboriculture jobs. 


The nursery “marries art, equity and ecology” into a project that is of service to all of San Francisco, said Swae. He’s particularly proud of the aesthetic elements, including murals and two porch swings, the communal gathering areas and the sweeping pergola over the shipping containers. Additionally, the site is completely powered by solar, so there will be no use of greenhouse gases to fuel operations.

 Gov. Gavin Newsom and Mayor London Breed lead the ribbon-cutting ritual.

During the ribbon-cutting ceremony, guests admired lush plants – methodically placed by Bureau of Urban Forestry landscape and cement crews – and the new solar-paneled office and classroom structures. Nearby, once drab gray freeway pillars had been emblazoned with bright green and yellow original artwork.


“This property has been pretty much not used,” Mayor London Breed said of the transformed Caltrans lot, as she took in the view of smiling faces gathered at the opening ceremony. “And now it’s going to be made into something exciting, something sustainable and something open and available for the community.”

 

The project received $3.8 million from the state Department of Transportation (Caltrans) by way of Gov. Gavin Newsom’s Clean California initiative. The California Department of Forestry and Fire Protection contributed $1.2 million and the City supported the effort with $1 million.

Public Works Director Carla Short, an arborist by training, said the street tree nursery will serve as an important hub “for elevating environmental and economic justice” through stewardship of San Francisco’s urban forest.

 

Getting the project ready in time was no easy feat.

It was a scramble to deliver the project by November, after breaking ground in June, said Ruby Yu, the Public Works construction manager for the project. Caltrans was an indispensable partner throughout, she added.

The nursery will be overseen by Public Works’ Bureau of Urban Forestry, with an on-site nursery specialist and volunteer and outreach coordinator. In the coming weeks, urban forestry landscape crews will be installing irrigation for platforms on which the young trees will grow. The Public Works carpentry and paint shop teams are building tables and seating for the nursery classroom, crafting the furniture from a felled 24th Street ficus tree.

Ramaytush Ohlone culture director Gregg Castro capped the ribbon-cutting ceremony with a blessing song.


"I went around and did a circle around the trees to let them know I’m here, and that we’re back, and we are going to take care of them,” Castro told the small group gathered for the blessing, while beating a rattle in the palm of his hand. “We are going to do that with the help of all of you. There’s only a few of us. We got pushed out a long time ago, but our sacred responsibility to take care of the land is still with us. And we are going to do that through you.”

APEC

A splash of delight adorns this Chinatown crosswalk at Stockton and Washington streets.

APEC Summit – A High-Stakes Event with Lasting Benefits

This month, San Francisco hosted the APEC summit – a week-long event that brought to town President Biden, nearly two dozen other world leaders and large contingents of corporate executives, journalists and government officials from across the globe.

APEC, officially known as the Asia-Pacific Economic Cooperation, kicked off on Nov. 11 and wrapped up a week later. 

This was a big deal for San Francisco, putting the City on the international stage. As a City, we strove to put our best foot forward with the goal of rebalancing the narrative that San Francisco is caught in a doom loop; we also wanted to highlight the bloom loop and show off our incredible city – the beauty, the diversity and the vibrancy.

“My hope is that people will have the opportunity to experience San Francisco for themselves and tell the whole story,” Mayor London Breed said during a press conference leading up to the summit.

The conference was expected to generate tens of millions of dollars in economic activity and highlight that San Francisco’s hospitality industry – one of the City’s most important economic sectors that creates jobs, supports local businesses and yields much-needed tax revenue – is welcoming and open for business.

Given the presence of the U.S. president and other heads of state, APEC was a high-security event – with federal law enforcement agencies taking the lead on that front. It necessitated temporary road closures and checkpoints that impacted travel and limited access in some areas of town.

The City had been preparing for this event for nearly a year, with work ramping up since early summer. The all-hands-on-deck effort involved Public Works, the San Francisco Municipal Transportation Agency, the Recreation and Park Department, the Port of San Francisco, San Francisco International Airport, the Office of Economic and Workforce Development, the Department of Emergency Management, the Department of Public Health, the Fire Department, the City Administrator’s Office and many others.

 

As we do for any large event, whether it’s a sports team’s victory parade or a Pride celebration, Public Works conducted focused cleaning operations in the high-activity areas. For APEC, that meant the South of Market, the downtown hotels, Chinatown, Nob Hill and the Outer Richmond. It’s important to note that crews continued to respond to service requests in the City’s other neighborhoods.

We also refreshed the landscaping near Moscone Center, pruned and planted trees and spruced up tree wells along Market Street and in the South of Market. Our skilled trades workers were dispatched to the Legion of Honor, the site of a gala dinner, to work on the bathrooms, the exterior fountain, the light poles and the electrical system. While driven by APEC, the benefits extend into the future.

 

The same is true for a trio of community-driven neighborhood beautification projects that we managed.

We brought in contractor crews to install two new decorative crosswalks – one, at Stockton and Washington streets in Chinatown, displaying a series of whimsical clouds; the other, at Stockton and Union streets in North Beach, boasting the colors of the Italian flag. They’re great additions to our city streetscape that will be enjoyed for years to come.

The pedestrian crossing over Geary Boulevard now pops with color.

The third beautification project is the new paint job on the Webster Street Pedestrian Bridge, which we feted with a joyous community celebration.  

The utilitarian bridge, which spans Geary Boulevard, is much more than a pedestrian crossing. At its core, it’s a connector between two communities – Japantown and the Fillmore/Western Addition, which were physically torn apart during the redevelopment era more than 50 years ago. 

Eyed for demolition just a few years back, neighborhood leaders, residents and merchants fought back. Not only did they prevail in preserving the bridge, but they advocated for improvements. And this month, they got their wish.

Community representatives and City officials pause on the bridge during their ceremonial walk.

The bridge, which was once bare gray concrete, now stands out in a radiant vermillion, chosen to resemble the color found on traditional torii gates in Japan that symbolize gratitude and harmony.

The refresh also included repairs to cracks in the concrete and the hanging lanterns that light the pathway.

This was a team effort through and through, with the Japantown Community Benefit District and the Japantown Merchants’ Association playing a big role in championing these improvements, Public Works delivering the job and the San Francisco Municipal Transportation Agency funding the improvement project.
 

We celebrated the completion of this beautification project on Nov. 2 with a ceremonial inaugural walk across the bridge. Mayor Breed, Consul General of Japan Osumi Yo and community leaders from Japantown and the Fillmore joined us for the event. It was an amazing, meaningful moment, with folks walking arm-in-arm across the bridge, cementing their deep connections and shared history. 

With APEC now over, Public Works is eager to keep the momentum going to keep our neighborhoods clean and beautiful. We are asking frontline staff what worked well and why and how our routine cleaning and maintenance operations could benefit. We also want to continue the effective coordination we experienced with other City agencies to make sure we leverage each other’s work to deliver high-quality services more effectively to San Francisco’s residents and visitors.

Mayor Breed Taps
Carla Short to Serve as
Public Works Director

Mayor London Breed announced on Nov. 8 the appointment of Carla Short as the new permanent director of San Francisco Public Works, calling her pick “the right person for what is one of the toughest jobs in the City.”

Short, a veteran of the department, had been serving as interim director since 2021.

“Carla Short has clearly demonstrated that she is hardworking, collaborative and committed to improving San Francisco,” Breed said in her announcement. “From the first day she stepped into this job, she never wavered from taking on challenges and embracing opportunities to move our City forward.”

Short – a native of St. Louis – first joined Public Works in 2004 as the City’s Urban Forester and soon rose through the ranks, moving into the Bureau of Urban Forestry’s top position in 2015. She filled in as the Department’s Deputy Director for Operations for eight months starting in the fall of 2019 and served as Deputy Chief of the Bureau of Street-use and Mapping.

A certified arborist, Short graduated from Yale University with a Master of Environmental Management and will be the first woman to lead Public Works in the department’s 123-year history.

Though she initially had planned to eventually return to her roots at the Bureau of Urban Forestry, Short said her two years at the helm of the department made her appreciate “what an amazing opportunity it has been working with the whole department” – witnessing the talent, professionalism, dedication, camaraderie and determination that Public Works staff bring to work every day.

“I am incredibly honored that Mayor Breed has confidence in me but that really reflects the confidence in the Public Works team,” she said.

Short emphasized her commitment to build on and expand the partnerships that Public Works has cultivated with residents, merchants and community groups, as well as other City agencies, to collectively improve our shared urban environment.

 

“I really believe San Francisco is moving in the right direction – let’s move beyond the doom loop narrative and focus on the bloom loop that’s developing,” Short said. “Public Works plays a big part in San Francisco’s march forward.”
