Mayor London Breed hopes to send a $360 million bond to San Francisco voters in November to fund a variety of infrastructure projects and public space improvements, including seismic safety work at the city’s public hospital and upgrades to two key transit plazas. 

Breed announced Monday that her proposal would provide $167 million to help finance retrofits at San Francisco General Hospital and the Laguna Honda public nursing home that recently survived a threatened closure by the federal government. The money would further help renovate and expand the decades-old Chinatown Public Health Center on Mason Street above the Broadway Tunnel.

Also included in the bond would be $70 million for road repairs and $50 million to help shelter and house homeless families, either by buying new sites or renovating existing ones. The city would further plan to use the bond to invest $25 million into a facelift of Harvey Milk Plaza at the Castro Muni station, as well as an elevator repair and other enhancements to Powell station’s Hallidie Plaza.

A spokesperson for Breed said the bond measure would not raise taxes and would instead maintain current tax levels. It comes as recent San Francisco bond measures have seen mixed results: Voters approved a $300 million affordable-housing bond in March but rejected a $400 million bond for transit improvements in June 2022.

Breed is proposing the latest bond for the same election in which she will try to fend off four serious challengers at a time when voters are discontent about the state of the city — and, potentially, questioning the high cost of public projects such as redesigned trash cans, cabins for homeless people and even a toilet in Noe Valley. 

Breed said in a statement that her new bond proposal was part of her efforts to “make San Francisco a vibrant and healthy city.”

“This bond will invest in our critical infrastructure and advance projects that create jobs and prioritize important civic needs,” Breed said. “It will create safer streets and smoother roads, deliver welcoming and vibrant plazas and public spaces, support families, and strengthen our public health institutions that serve all of our residents.”

Breed’s office said she expects the proposed bond will be sent to the Board of Supervisors for consideration in the coming weeks, after approval by a City Hall capital planning committee. A supermajority of eight supervisors would need to agree to put the measure on the Nov. 5 ballot, where it would then need approval from two-thirds of voters. 

The proposal already has support from a range of community leaders who said the projects the bond would pay for are sorely needed in San Francisco. 

Kim Meredith, CEO of the San Francisco General Hospital Foundation, said in a statement that the measure would fund earthquake-safety upgrades, “critical repairs and much needed renovations to deliver quality care … for all San Franciscans.” Similarly, Sarah Wan, executive director of the Community Youth Center of San Francisco, said the planned renovation of the Chinatown Public Health Center would help the facility continue providing essential services to the Chinese American community, as it has done for many years. 

“Our community needs a state-of-the-art medical center to fully meet the growing needs to provide health care services for the next generation of our youth, families, and growing AAPI senior population in San Francisco,” Wan said in a statement. 

LGBTQ-rights activist Cleve Jones, a close friend of the late Supervisor Harvey Milk, said the bond would help pay for a long-planned memorial that would make Milk’s namesake plaza at Castro and Market streets “a beacon to others all over the world.” 

“Its very existence will give hope to people who need it,” Jones said in a statement. “And it is my hope that it inspires others all across the world to become a hero in their own communities, because the world needs a lot more people like my friend, Harvey Milk.”

But some community leaders were critical of Breed’s proposal because it did not include improvements to the San Francisco City Clinic, a SoMa health facility that provides low-cost testing for sexually-transmitted infections and treatment as well as HIV prevention and treatment services. Officials had previously discussed including $29 million for the clinic as part of the November bond. 

Jeffrey Kwong, president of the Harvey Milk LGBTQ Democratic Club, said the clinic is “dilapidated” and in need of investment. He said the mayor appeared to favor the plaza projects and sidewalk improvements over the clinic and urged the capital planning committee to reconsider. 

“It’s irresponsible for the mayor, and I think it’s because she’s running for reelection,” Kwong said. “She wants to spread out political goodies, but that’s now how the bonds should work, and it’s indicative of a lack of planning on her part.”

Breed spokesperson Jeff Cretan said in a statement that the clinic is “an important public health resource and we are exploring options for (its) future.” The clinic will continue to operate while Breed’s administration works on “investments to improve the patient experience,” Cretan said.

Board of Supervisors President Aaron Peskin, who sits on the capital planning committee and is running for mayor against Breed, said he supports funding the clinic through the bond measure. 

“The city of San Francisco has a lot of ailing infrastructure and a well thought out 10-year capital plan that we have been chipping away at year after year,” Peskin said. “The mayor’s initial proposal, while all of the things in it are laudable… some of them are need-to-have’s and some of them are want-to-have’s.”

Peskin said he was “confident that we’ll have mature discussions in the intervening few weeks and we’ll put it back together again.” 

Supervisors have until late July to submit the bond measure to the elections department.
