SF YIMBY, a pro-housing group, is criticizing District 4 Supervisor Alan Wong, whom they endorsed, for his stance on a 100% affordable housing project at 2550 Irving St., due for completion in March 2026. They object to his concerns about toxins and his approach to a proposed senior affordable housing project, despite his initial support for upzoning and the group's endorsement. The chapter is considering rescinding the endorsement if the situation worsens.

The pro-housing group urged San Franciscans to celebrate Wong’s campaign-headquarters opening, and its members went out doorknocking for him on Irving Street and near McCoppin Square just last weekend. But now, the YIMBYs are publicly chastising their endorsed candidate, objecting to his position on toxins near one affordable housing project at “His decision to create an inflammatory, NIMBY petition purporting risks to public health is based on scientifically unfounded claims that were thoroughly disproven during the permitting process,” read aThe chapter urged the supervisor to withdraw his petition on 2550 Irving St. and fully support the project at 1234 Great Highway. If things get more heinous, said Dane Willette, a lead at the chapter, rescinding the endorsement could be on the table, though so far the chapter is still “comfortable” with its choice. calling for “a complete cleanup of toxic vapors” beneath a block of Irving Street between 26th and 27th avenues, where tenants will move into an affordable housing project at The developer and the California Department of Toxic Substances Control said they’ve installed a Vapor Intrusion Mitigation System — essentially, a barrier between the site’s foundation and the building to mediate the toxic vapors. But Wong and a Sunset neighborhood group want more thorough testing and cleaning on and around the site. , a group that has consistently moved to stop the project from breaking ground since 2021, citing inadequate monitoring of toxins. The goal, Wong wrote, is to ask the developer, the Tenderloin Neighborhood Development Corporation, and other stakeholders to “fund and support a comprehensive cleanup plan for the entire neighborhood.” to stop the development and asked for a complete soil cleanup to remove PCE, a chemical used by dry cleaning businesses that may increase risks of cancer at high concentrations The developer and the California Department of Toxic Substances Control said they have conducted extensive tests — though not the tests that the neighborhood groupBut those measures, Wong wrote in a statement, were only meant to protect residents of the building, but “neighbors in the surrounding affected areas remain concerned” and want “more than a narrow, site-only response.” With the project already built, Wong wrote, “we should do more than satisfying what is technically required and clean up contamination.”SF YIMBY is also disappointed at Wong’s position on a proposed senior affordable housing project at 1234 Great Highway in the Outer Sunset, which stalled due to funding challenges.if he would move the project forward, cited residents’ concerns over the formerly homeless population who may move in. The ambiguity wasn’t encouraging to YIMBYs, who wanted an enthusiastic yes. “We expect better from a city supervisor than peddling NIMBY conspiracy theories and opposing affordable housing projects in his district,” the YIMBY statement continued. When the SF YIMBY chapter was making its endorsements, the members voted firmly to endorse Wong, Willette said. None of the declared District 4 candidates have a huge pro-housing record to run on, and Wong, uniquely, supported the upzoning plan — a big factor in the endorsement decision. “To see it pop up again, especially from Wong, was a shock,” Willette said. Wong circulating the petition “disrupted our discussions in terms of how much more to push the candidates,” he said. The June elections in District 2 and District 4 are of higher priority for the YIMBYs. They are facing a similar dilemma in District 2, where Supervisor Stephen Sherrill, who supported the upzoning plan and won the chapter’s endorsement, is “We are a big constituency,” said Willette. “We hope that for Wong, being pro-housing is not just for election chances but for the future of our city.” “We do stand by Wong. We still believe he’s the best and most pro-housing candidate in District 4,” he said. “That could change if more things come out. But we are still confident.”Because of you, Mission Local reached and surpassed our $300,000 year-end fundraising goal.Thank you for choosing to invest in a local newsroom rooted in San Francisco’s communities — one that listens first and reports deeply.

Junyao lives in the Inner Sunset. You can find her skating at Golden Gate Park or getting a scoop at Hometown Creamery.MSNA’s first objection to the 2550 Irving project was the threat of crime from poor folks. When shamed for that, they switched to lawsuits over height and traffic. Only when those cases were dismissed, did we start hearing about toxins. That’s why the pretextual concern over an issue that the DTSC is already handling looks like a NIMBY in environmental clothing.Alan Wong is against toxic vapors? Someone tell Alan Wong, the guy who wants to bring machines that spew toxic vapors back next to Ocean Beach.Putting this work on TNDC, a non profit affordable housing builder that’s been supporting San Francisco’s most vulnerable citizens for going on 50 years is absolutely anti affordable housing. If Alan Wong wants to clean up the surrounding area then he can do this thing called “being a supervisor” and find the public funds to do that.If there’s no scientific basis that there’s a public health risk from PCE in the ground, if this a conspiracy theory – the question deserves asking how the developer and the California Department of Toxic Substances Control have come to find it necessary to install a Vapor Intrusion Mitigation System for the building. Yeah this hits a nerve of course. There’s a long history of gaslighting the Westside when operators from elsewhere don’t want to spend the money. Right off the top of the head: Letting Great Highway fall into the ocean and claim global warming is to blame for beach erosion , years of stonewalling on the expansion of the Auxiliary Water Supply System , BRT on Geary instead of a proper underground service .Yeah, except nobody said that “there’s no scientific basis that there’s a public health risk from PCE in the ground.” The links to prior articles in this article do a pretty solid job of explaining the actual situation out there.2550 Irving is already complete and ready for new residents. Alan Wong supports neighbors’ concerns about health risks, even after the project is finished. Calling his support for removing toxins a NIMBY move makes no sense. The project is done. Alan Wong cares about public health. The YIMBY group should move on instead of using this kind of rhetoric.The dry cleaning toxins in the soil were released by several neighborhood businesses decades ago. PCE can stay in the soil for decades, long after the original dry cleaning businesses that put in the soil have closed their doors. Making the affordable housing project pay for cleaning up the entire neighborhood is unreasonable because it would impose substantial costs on the project, rendering it infeasible. It’s a NIMBY trojan horse that would functionally stop the project, while still allowing proponents of this position to say that they aren’t opposed to affordable housing . If Alan Wong is serious about cleaning up the mess in the soil, he should get the city to pay for it, or track down the original proprietors of the dry cleaning businesses that contaminated the soil in the first place and make them pay for the clean up.That comment makes a lot of sense. Just because Supervisor Wong wants to clean-up toxins does not mean he’s against affordable housing. The building is already built. Why leave any toxins in the ground if you can remove them and protect the public?Please keep your comments short and civil. Do not leave multiple comments under multiple names on one article.
