Planning panel advances Trinity Plaza redevelopment with conditions after months of debate

The San Francisco Planning Commission on Aug. 3 certified the environmental impact report for the Trinity Plaza redevelopment and forwarded the project’s development agreement with amendments and conditions to the Board of Supervisors, after an extended public hearing that drew tenants, housing advocates and business groups.

The project sponsor proposes about 1,900 rental units, including 360 on‑site replacement rent‑controlled units for existing Trinity Plaza residents, roughly 60,000 square feet of commercial space and substantial new open space. Planning staff described nine separate entitlement actions the project requires, including zoning map and general plan changes, a special‑use district and a development agreement.

Why it matters: Supporters said the deal protects current tenants and injects private investment to revive a long‑troubled block of Mid‑Market. Opponents and community groups pressed the commission to limit commercial parking and to require more deed‑restricted affordable housing rather than relying on rent control and negotiated commitments.

The commission voted in a series of discrete motions. It found that net new shadow on Civic Center Plaza and Howard Langton Mini Park was not adverse after receiving the Recreation & Parks Commission’s recommendation. The body then certified the EIR unanimously and approved CEQA findings as modified to defer some numeric inclusionary‑housing language to the eventual development agreement. Commissioners amended several motions to make findings consistent and to record outstanding concerns for the Board of Supervisors’ review.

Tenants’ advocates framed the deal as a hard‑won tradeoff. Randy Shaw of the Tenderloin Housing Clinic told the commission the package ‘‘adds up to 34%’’ as a combination of the replacement rent‑controlled units plus the project’s on‑site affordability commitments. Supporters said the replacement units and other protections mean the project preserves housing that could otherwise be lost.

But critics and some commissioners urged caution on parking. Neighbors and transit‑advocacy groups warned that adding commercial parking would generate additional vehicle trips and could undermine the city’s transit‑first goals. Several commissioners asked staff and the developer to clarify whether commercial parking should be tied to the amount of commercial space rather than locked as a flat number in the development agreement.

The commission’s action forwards the development agreement and its recommended modifications — including revised language on change thresholds in unit counts and stricter linkage between changes in commercial floor area and non‑residential parking — to the Board of Supervisors. The board will consider the final terms and any material modifications.

The next step: The Board of Supervisors will review the development agreement and the Planning Commission’s recommendations; several technical and policy items remain to be finalized there, including the exact inclusionary percentage and whether certain parking provisions are to be fixed or tied to commercial floor area. The Planning Commission recorded its findings and transmitted them for the board’s consideration.
