Commission votes intent to disapprove 2918 Mission housing project after shadow concerns at school playground

The commission on Sept. 27 took a motion of intent to disapprove the 2918 Mission Street housing project after a contentious hearing that focused on shadow impacts to adjacent school yards and the implications of invoking the state density bonus.

Planning staff described the project as a merger of three lots to permit an eight‑story mixed‑use building with 75 residential units that seeks concessions under California’s state density‑bonus law. Environmental planning staff updated the commission with a supplemental community plan evaluation and a shadow study that measured net new shadows on two school yards at Zaida T. Rodriguez early education school. The analysis found small annual increases in shadow on the pre‑K yard (0.2% annual theoretical sunlight) but a larger yearly increase for the transitional kindergarten yard (roughly 17% annual net new shadow), with the study showing the new shadow would cover substantial portions of the yard during early morning recess periods at certain times of the year.

Public commenters — including preschool directors, parents and neighborhood advocates — urged the commission to halt or reduce the project because students’ morning recess periods would lose sunlight, potentially affecting health and play time. “I don’t see how you can call a 63% increase in the shadow, insignificant,” Commissioner Melgar said during deliberations, quoting testimony about the transitional kindergarten yard’s morning coverage.

Commission action: On a motion for intent to disapprove, the commission voted 4–3 to register an intent to disapprove and to continue the item to Oct. 11 to allow staff to prepare a draft motion. Commissioners who opposed the motion cited the constraints of the state density‑bonus law and the limited tools available to deny projects that meet state entitlements. Staff noted that the applicant’s base‑density calculations were part of the administrative record (staff said the base calculation was included in an earlier packet), and the commission set a follow‑up to draft formal actions.

Context and next steps: The item illustrates a continuing tension in San Francisco planning: local inclusionary and design goals versus state density‑bonus rules that can reduce on‑site affordable housing percentages. The commission’s intent‑to‑disapprove vote indicates substantial concern about the proposed project’s impact on school yard sunlight; the Oct. 11 continuation will allow a formal motion to be drafted and further legal and factual review to be completed.
