Commissions unanimously signal intent to raise Portsmouth Square shadow limit for senior‑housing project

The Planning Commission and Recreation and Park Commission unanimously expressed intent to allow a small increase in shadowing on Portsmouth Square to facilitate a proposed senior‑housing project at 740 Washington Street.

Planning staff described two linked requests: raise the park’s zero‑tolerance shadow budget and, later, allocate that additional budget to the proposed Self Help for the Elderly project. Staff said the project would demolish an existing building and construct a roughly four‑story building with about 18 affordable senior units and a ground‑floor senior center. Staff quantified the proposed increase as about 45,089 shadow square‑foot‑hours annually—approximately 0.0222% of the park’s potential annual sunlight—occurring in evening hours (roughly 6:30–7:30 p.m. between late April and mid‑August) and largely affecting a staircase/landscaped circulation area rather than the park’s primary program spaces.

Community testimony from Chinatown organizations and project supporters emphasized the project’s community benefit: donor intent for the property, the need for senior housing and an on‑site senior center, and that much of the new shadow would fall on a stair/planting area used for circulation. Community representatives submitted suggested criteria they want the commissions to consider before final allocation—such as limiting shadow during core daytime hours and prioritizing nonprofit projects with direct community benefits—but staff advised that an intent vote cannot be conditioned on a specific project and that allocations/conditions will be considered in later hearings.

After discussion, the Planning Commission moved an intent to increase Portsmouth Square’s cumulative shadow limit by 0.022% and voted unanimously in favor; the Recreation and Park Commission also voted unanimously to register intent. The commissions’ action was an intent to proceed and to provide staff direction for CEQA and future hearings; it is not a final change to the park’s criteria. Staff said it will return with CEQA materials and an updated shadow memorandum to clarify measurement and joint hearing procedures.

Next steps: Staff will incorporate the commissions’ intent into CEQA documents; any final allocation of shadow or conditions will occur at subsequent entitlement hearings where project design, community benefits and mitigation will be evaluated.
