Board upholds Planning Department exemption for Octavia Street project after lengthy hearing

The San Francisco Board of Supervisors voted unanimously on April 20 to uphold the Planning Department's issuance of a Class 1 categorical exemption under the California Environmental Quality Act for a renovation and rear addition at 2651–2653 Octavia Street, rejecting an appeal filed on behalf of neighbors and library supporters.

Appellants had urged the board to reverse what they called a second "inappropriately issued exemption" and require a full CEQA study before the project proceeds. "We request that the board overturned the second inappropriately issued exemption and require that the planning department not bypass CEQA but analyze the evidence in 1 document for public review," appellant Maureen Holt told the board during the hearing.

The board's decision followed presentations from the appeal supporters, the Planning Department, the San Francisco Public Library, and the project sponsor. Planning Department staff said they re-examined the board's prior direction, had an independent daylight study prepared, and found "the project would not substantially reduce the library's indoor illumination levels as compared to the existing conditions." Planning staff also told the board that, after reviewing historical reports and landmark work, "indoor light level or indoor quality inside the library's main reading room is not a character-defining feature of the library."

Why it matters: The Golden Gate Valley Branch Library is treated in the record as an historic resource and neighbors and preservation groups argued that reductions in natural light and new shading on the library's rooftop solar array could materially impair the library's character and energy function. The appellants submitted external expert critiques and said the Planning Department's studies contained methodological inconsistencies. The Planning Department and the project sponsor countered that multiple daylighting analyses, including vendor and sponsor-provided studies, showed only minimal changes in interior illumination and small effects on solar generation, and that the library already uses low-e windows and interior shades that significantly reduce daylight under typical conditions.

Key facts and technical findings cited at the hearing: - Planning and sponsor analyses examined daylight at multiple interior points across different sky conditions; sponsor-reported figures showed natural-light-only changes of roughly '24% (partly cloudy), —4% (clear) and smaller reductions under combined natural-plus-electric lighting. The sponsor's reported numbers included: minus 4% on overcast, minus 11% on partly cloudy, and minus 1.8% on clear days for natural light comparisons; combined natural+electric scenarios produced still smaller changes. (Project sponsor presentation.) - The Planning Department noted the library has 14 large windows and the proposed project would reduce daylight from five of those windows; it concluded the effect would not "materially alter the library's character-defining features." (Planning Department.) - Appellants pointed to independent reviews and an architectural historian, saying the library's design intentionally maximizes natural light and that "substantial evidence" supports further CEQA review. They also noted the library's solar installation is part of the San Francisco Public Library's green program and argued the city should evaluate shading impacts fully.

What the board decided: After hearing presentations and public comment from neighbors and preservation advocates, and reviewing the Planning Department's record and supplemental materials, the board voted to affirm the Planning Department's January 27, 2021 categorical exemption (Item 18 on the agenda). The motion to approve Item 18 passed unanimously (11 ayes); Items 19 and 20 (motions to conditionally reverse and to direct preparation of findings) were tabled. In making the motion, Supervisor Stephanie said she visited the site and library and concluded the record met the "substantial evidence" standard supporting the Planning Department's determination.

Voices during the hearing: Supporters of the appeal included library patrons, the Library Users Association, and the Golden Gate Valley Friends; callers described the library as a community center with frequent programs and noted donor-funded renovations and a solar array. The Planning Department and the San Francisco Public Library's facilities director told the board the library staff had "no concerns" about the project's effects on interior light levels or solar panels. Project owner Jane Cote Cook and counsel argued the appellants had not met the legal burden to overturn an exemption and emphasized extensive technical work by their consultant, Symphysis Bioclimatic Design.

Next steps: The board's action affirms the Planning Department exemption, clearing the way for the project sponsor to proceed under the existing approvals unless further legal action is filed. Because the board's previous 2020 motion required Planning to analyze the light issue, the department's new analysis and today's vote brought the matter to a final decision at the legislative level.

Ending note: The hearing drew substantial public participation: multiple experts and neighborhood advocates submitted reports and dozens of neighborhood residents spoke by phone in support of the appeal; the board's decision turned on the Planning Department's conclusion that the record contains "substantial evidence" that the project does not substantially and materially alter the library's historic features.
