OCII changes Mission Bay South signage rules to allow taller highway‑facing signs

The commission on March 17 adopted environmental review findings pursuant to the California Environmental Quality Act and approved amendments to the Mission Bay South Design for Development and Signage Master Plan allowing wall signage on western facades of commercial/industrial buildings west of Owen Street to extend up to 80 feet in height (from the prior 45 feet) for better visibility from Interstate 280.

Assistant Project Manager Ethan Warsh told the commission that I‑280 runs adjacent to the western edge of several Mission Bay South blocks at roughly 45 feet elevation, which can block signage mounted at the previously permitted 45‑foot height. The proposed amendment raises the permitted western‑facing height to 80 feet while limiting that portion of the facade to a maximum of 200 square feet of the parcel’s 300 square‑foot signage allowance — the 200‑square‑foot limit mirrors the planning code’s highway sign cap. The amendment also contains an automatic adjustment clause to lower the permitted height back to 45 feet within one year if the freeway is removed or reduced in height.

Commissioners asked about visibility from different vantage points and which buildings would be affected; staff identified Kaiser, Kilroy/Block 40, Gladstone and certain Alexandria/UCSF buildings as likely beneficiaries where wayfinding to medical facilities is an important factor. Public commenter Ace Washington urged historical recognition within Mission Bay; the commission approved the signage amendments by roll call (3 ayes, 1 absent).
