See our November 2024 SF Voter Guide for a nonpartisan analysis of measures on the San Francisco ballot, for the election occurring Nov. 5, 2024. The following measure is on that ballot.
Proposition K would start a process that could, about a year later, permanently close a large section of San Francisco’s Great Highway to car traffic so that the city could later turn it into a park. The measure would not fund the design or creation of the park.
The measure would affect a section of roadway called the Upper Great Highway, a 2-mile stretch along Ocean Beach on the city’s western edge, from Lincoln Way to Sloat Boulevard.
Proposition K marks the latest chapter in a saga that began early in the COVID-19 pandemic. At that time, the Board of Supervisors closed the Upper Great Highway to vehicle traffic so that residents could walk and bike there while social distancing, to slow the disease’s spread — a move that was widely popular. In 2022, the board approved a pilot project that kept the street closed to cars on weekends but open to them during weekdays. The pilot project is set to end at the close of 2025, at which point the board would decide whether to change the road’s use.
If passed, Proposition K would decide the Upper Great Highway’s fate instead.
Listen to a summary of what this ballot measure would do.
Support
Five San Francisco supervisors co-sponsored Proposition K’s placement on the ballot: Myrna Melgar, Dean Preston, Rafael Mandelman, Matt Dorsey and Joel Engardio, who has been the most vocal of the measure’s advocates. Engardio represents the Sunset District, which contains the Upper Great Highway.
Proposition K is a “once-in-a-century opportunity” to transform the road into an iconic oceanside park that could bring the Sunset to life, Engardio has said.
Proponents say that the highway’s pilot project has been a success, drawing an average of 4,000 visitors per weekend day. Making the road a permanent park could boost business opportunities, reduce automobile pollution in the area and create more safe space for pedestrians and cyclists to enjoy the beach, they say. The park would also increase coastal access for people with mobility challenges, such as wheelchair users and those with physical disabilities.

Proposition K has secured support from prominent political figures, including Mayor London Breed, Speaker Emerita Nancy Pelosi, state Sen. Scott Wiener, BART Board director Janice Li and former District 1 Supervisor Eric Mar.
Friends of Great Highway Park, a group that hosts events and activities on the roadway during weekends, has advocated loudly for the proposition. Other supporters include a diverse array of organizations focused on urban planning, environmentalism and local politics, like Livable City, the San Francisco Bicycle Coalition, Sierra Club, SPUR, the San Francisco Democratic Party, San Francisco YIMBY and GrowSF.
Opposition
Since the proposition’s announcement, it has divided residents on San Francisco’s west side. Opponents expressed frustration that Engardio did not consult them before deciding to place it on the ballot. They argue that it’s unfair for voters citywide to decide their neighborhood’s future.
Opponents say the Upper Great Highway is vital for north-south travel, and permanently closing it to vehicles could worsen traffic and divert it into residential areas, as well as lengthen commutes — a recent study by the city’s transportation agency found a minor potential impact on commutes. Some merchants worry that these inconveniences would discourage long-time customers from continuing to patronize them.
District 1 Supervisor Connie Chan represents the Richmond District, home to many Great Highway commuters in the city’s northwest. She opposes the ballot measure, arguing that it’s too extreme; she has proposed converting only half the road into recreational space and keeping the rest of it open to cars.
Some prominent local groups representing Chinese and other Asian American residents oppose Proposition K, including the Edwin M. Lee Asian Pacific Democratic Club, Chinese American Democratic Club and Chinatown Merchants United Association of San Francisco.
Aaron Peskin, Board of Supervisors president and a mayoral candidate, also opposes Proposition K, calling it divisive and an “unfunded mandate.” Mayoral candidates Daniel Lurie and Mark Farrell oppose Proposition K, too.
Other detractors include Open The Great Highway, a group formed to oppose the road’s closure, and several neighborhood groups, including Planning Association for the Richmond, Coalition for San Francisco Neighborhoods and Neighborhoods United SF.
What it would do
Proposition K would not immediately and permanently close the Upper Great Highway to cars and transform it into a park.
Instead, the measure’s passage would begin a long bureaucratic process, involving numerous local and state government agencies, that would lead to that outcome.
Because the measure would not create funding for the park, officials would have to find a way to pay for it.
If voters passed Proposition K, then the San Francisco Planning Department would propose changes to the land-use rules governing the Upper Great Highway so that it could become a park. The Board of Supervisors would publicly review that proposal, and residents and concerned citizens could attend hearings and offer comment.
The board would likely approve the proposal, as rejecting it could be seen as “not implementing the will of the voters,” said Jonathan Goldberg, legislative aide to Supervisor Engardio. That would be “unheard of,” he added, and could expose the city to risk of lawsuit.
To proceed, the city would also need approval from state regulators.
At that point — possibly 10 months to a year after Proposition K’s passage, at the soonest — the San Francisco Recreation and Parks Department could start designing the new park, a process that might take several years, Goldberg said. In the meantime, the department could apply to close the road to vehicle traffic permanently, so that it could be used entirely for recreation.
The Recreation and Parks Department did not respond to requests for comment about its role in implementing Proposition K.
Cost
The San Francisco Controller’s Office analyzed what it would cost City Hall to manage the Upper Great Highway after permanently closing it to car traffic — a scenario that Proposition K’s passage would enable, but not immediately bring about.
The office’s analysis did not include the costs associated with obtaining regulatory approval for the closure. It also omitted design and construction costs for a new park.
By closing the Upper Great Highway to car traffic, the city would save an estimated $1.5 million in one-time infrastructure expenses, Deputy Controller ChiaYu Ma wrote in the office’s analysis. That factors in $4.3 million that the city would avoid spending on canceled road construction and traffic signal replacements, offset by $860,000 to $2.7 million in new costs for traffic calming measures and traffic lights to divert vehicles from the Upper Great Highway to alternative routes.
Keeping the road closed to cars may cause increased expenses for trash collection and other operations, Ma said. But overall, the city would save $350,000 to $700,000 each year in reduced road and traffic light maintenance, as well as sand removal.
Campaign finance
As of Oct. 7, the “Yes on K” campaign committee had raised $608,553, according to data from the San Francisco Ethics Commission.
Much of that money has come from leaders in tech and finance, including $350,000 from Yelp CEO Jeremy Stoppelman; $75,000 from Emmett Shear, a partner at venture capital firm Y Combinator; $50,000 from Anatoly Yakovenko, CEO of Solana Labs, a public blockchain platform developer; and $49,900 from the Benjamin Spero, managing director of Spectrum Equity, an investment firm.
The “No on K” campaign committee had raised $110,645. Matt Boschetto, a candidate in the District 7 supervisor race, created the committee.
By a quirk of election laws, the measure-focused committee lacks the per-person $500 contribution limit that applies to committees focused on getting candidates into office. Boschetto cannot legally use the funds from “No on K” for his supervisorial campaign. Boschetto’s father, Michael Boschetto, had contributed $50,000 to “No on K,” while the Boschetto Family Partnership added $10,000 and Matt Boschetto himself gave $5,000.
Anti-Proposition K group Open the Great Highway is the target of an ethics complaint, which alleges that it fundraised without first registering as a political action committee.
History and context
Proposition K is highly controversial. Both supporters and opponents have contested how it is presented to voters, from its title on the ballot to its official financial analysis. It has been the focus of numerous political demonstrations and media roundtables, and candidates in many supervisorial races have invoked the issue in their campaigns.
In 2022, San Franciscans considered a ballot measure that would have ended the Upper Great Highway pilot program and allowed cars back on the road seven days a week, as well as let cars resume driving on John F. Kennedy Drive in Golden Gate Park. Voters overwhelmingly rejected the measure, with 65.11% voting against it.
Closing the Upper Great Highway could leave the city’s Chinese American community feeling isolated, said Supervisor Chan at a recent debate on Proposition K, hosted by local radio station KALW. Chan, the only Asian American on the Board of Supervisors, said that Chinese residents frequently use the thoroughfare to travel between the Richmond and Sunset districts, both of which have historically served as cultural hubs for the community. But, of all drivers who take the Upper Great Highway, just 5% use it to commute between those districts, according to a 2021 study of pre-pandemic traffic data. Most drivers use it to get to the South Bay, the study found.
The section of road south of the Upper Great Highway, which is called the Great Highway Extension and connects the Sunset District to Daly City, has already been slated for closure due to coastal erosion. The Upper Great Highway faces a moderate risk of erosion, with its southern portion particularly affected.
