Neighbors demand DTSC, TNDC and City Hall
"Clean It Up Before You Build It Up"

In 2019 a series of environmental investigations—sparked by the potential sale of the Police Credit

Union building at 2550 Irving St. to affordable housing developer, TNDC—disclosed the presence of

hazardous levels of PCE, a cancer-causing solvent used by dry cleaners.

For three years the Mid-Sunset Neighborhood Association (MSNA) has asked city and state

agencies to address the contamination issue promptly and comprehensively. From the mayor’s

office to many media outlets, MSNA’s pleas have largely been ignored or dismissed as a NIMBY

tactic. The community has continually emphasized that its concerns are not aimed at stopping or

delaying the construction of the affordable housing project. Rather, their rallying cry is "Clean it up

BEFORE you build it up." (The SF Examiner published a good background article with the headline

“The First 100% Affordable Housing in the Sunset Sits on Contaminated Soil.”)

Cancer causing vapors found in Mid-Sunset homes. Experts say residents have been breathing toxic air for decades. The neighborhood demands cleanup.

Mid-Sunset Neighborhood Association - Press Release, January 12, 2022

For further information contact Paul Holzman —


The California Department of Toxic Substances Control (DTSC) recently sent letters to Mid-Sunset homeowners informing them of elevated toxic PCE (tetrachlorethylene) vapors in their homes. PCE is a dry cleaning solvent that even at low levels of exposure causes multiple types of cancer and neurological diseases such as Parkinson’s.


Lenny Siegel, director of the Center for Public Environmental Oversight (CPEO), said that after reviewing these letters as well as public documents that show soil gas contamination throughout the area, “it’s clear that the whole neighborhood should be subject to a full environmental review.”

The recent letters from DTSC confirm that toxic PCE gas above the State of California’s screening level was measured inside the homes adjacent to the Police Credit Union property at 2550 Irving St. The source is a soil gas plume created by toxic releases from the two dry cleaners that operated in the immediate area for decades.

TNDC sued for noncompliance with BOS resolution urging compromise on 2550 Irving Street.

Nearly one year ago, the Mid Sunset Neighborhood Association accidentally learned from their Supervisor, Gordon Mar, that the Mayor’s Office of Housing and Community Development had awarded part of the 2019 Prop A funding to the Tenderloin Neighborhood Development Corporation to build a seven story affordable housing project at 2550 Irving Street.


Despite pleas from the community for greater transparency and engagement, especially with the high numbers of non-English speaking neighbors and seniors left out of untranslated Zoom-only meetings, TNDC has ignored the community’s key concerns over PCE contamination, scale and density.


Supervisor Mar has repeatedly gone on record

stating the neighbors have legitimate concerns and expressing his disappointment that TNDC and MOHCD have been unwilling to discuss compromise.

PCE Contamination on Irving Street, San Francisco:What Is Acceptable?

by Lenny Siegel

September, 2021


On the surface, the plan to construct about 100 affordable apartments on the site of the San Francisco Police Credit Union (PCU) building on Irving Street is a solid step forward to address the Bay Area’s growing housing crisis. However, beneath the surface of the Mid-Sunset property lies a toxic plume of tetrachlorethylene (PCE) vapors that poses a health threat both to current neighbors and future residents.


Still, despite pleas from the neighborhood, California’s Department of Toxic Substances Control (DTSC) has chosen not to require remediation of the PCE property, relying on passive mitigation to prevent exposure.
