Board affirms planning department on Sharp Park pump-house project; environmental review debate continues

The San Francisco Board of Supervisors on Tuesday affirmed the Planning Department's decision to issue a mitigated negative declaration (MND) for the Sharp Park pump-house safety and habitat enhancement project and denied an appeal seeking a full environmental impact report (EIR).

Supporters of the appeal, led by Brent Plater of the Wild Equity Institute, urged supervisors to require a full EIR, saying the proposed work could release toxic acid sulfides from pond sediments and would have cumulative ecological effects. "We're here to ask you today to order a full environmental impact report for the Sharp Park pump house project," Plater told the board during an hours-long hearing.

The MND covers limited work at Horse Stable Pond and the connecting channel to Laguna Salata, including removing emergent vegetation and sediment, constructing a perennial pond, and replacing a pump-house retaining wall. Planning staff and the Recreation and Park Department said the work is required by a federal biological opinion intended to protect the federally listed California red-legged frog and San Francisco garter snake, and that the project does not change existing pump protocols. "The project does not change these protocols in any way," Open Space Manager Lisa Wayne told supervisors.

Why it matters: Opponents contend the MND does not adequately analyze potentially significant effects, including the release of acid sulfides when sediments are disturbed and the possibility that repeated dredging would be needed if water-level management is not changed. Backers say the proposed measures, along with a monitoring and mitigation program, will restore breeding habitat while keeping worker access and pump infrastructure safe.

Board discussion and vote: Supervisors debated whether the factual record contains "substantial evidence" supporting a fair argument that the project could cause a significant adverse environmental impact that would trigger an EIR. After more than three hours of testimony from scientists, community residents and golfers, Supervisor Scott Wiener moved to affirm the MND and table additional motions to reverse the Planning Commission; Supervisor Norman Yee seconded. The board voted 7-4 to affirm the environmental finding and to table the related items. Wiener said he believed Planning had conducted its review properly; opponents argued new information from U.S. Fish and Wildlife Service communication warranted further study. "I do move to affirm the mitigated negative declaration, specifically, to move item 20 and to table items 21 and 22," Wiener said before the vote.

Public testimony: More than 70 speakers filled the chamber. Environmental groups urged an EIR, citing expert declarations and the potential for long-term, cumulative harm. Speakers representing golfers, youth programs and the City of Pacifica urged the board to allow the project to proceed, saying the work would improve habitat and protect infrastructure while preserving public recreation.

Mitigation and agency roles: The MND includes specific mitigation measures and a Mitigation Monitoring and Reporting Program. Planning staff and Rec and Park said the city is accountable for implementing mitigations and will submit studies and remediation plans to federal and state wildlife agencies for review; U.S. Fish and Wildlife staff said in a separate exchange that, at the time of one email cited by appellants, they had not identified resources to implement a particular mitigation. Planning and Rec and Park maintain that the city can and must implement the mitigation measures through permit conditions and the MMRP.

Formal action: By roll call, the board approved item 20 (affirming the Planning Department's MND) with seven ayes and four noes. The recorded vote was: Chu, Cohen, Farrell, Tang, Wiener, Yi and Breed — aye; Campos, Kim, Mar and Avalos — no. The board also tabled items 21 and 22, which sought to reverse the Planning Commission and direct findings, respectively.

What comes next: The board's decision lets Rec and Park move toward implementing the project as conditioned by the MND and the federal biological opinion, while opponents said they will evaluate legal options. Rec and Park officials said they intend to proceed with the habitat work and infrastructure improvements required by the federal biological opinion.

Ending note: The dispute underscores a broader tension about Sharp Park's future ' balancing endangered-species protections, public recreation and shoreline dynamics along the Pacific Coast.
