Planning commission hears detailed Moscone Center expansion plan and broad neighborhood support
Summary
Planning Department and project designers presented a package to expand and reconnect Moscone Center—adding roughly 500,000–580,000 sq. ft. of contiguous exhibition space and street‑level public realm improvements. City staff and many neighborhood groups urged pedestrian safety measures and committed mitigation.
San Francisco planning staff and the Moscone Center project team gave commissioners an extended informational briefing on July 24 about a proposed expansion designed to keep the city competitive for professional conventions and better connect the complex to surrounding neighborhoods. Elizabeth Waddie, assistant director of current planning, told the commission the proposal “would increase the Moscone Center facility by about 20%,” a change the team says will create roughly 515,000–580,000 square feet of contiguous exhibition space.
The presentation, led by city architects and Skidmore, Owings & Merrill partner Craig Hartman, outlined a plan that unites below‑grade halls under Howard Street, adds above‑grade meeting and ballroom space, and introduces a new lightweight “bridge of light” between halls. Edgar Lopez, deputy director and city architect, said the design emphasizes new pedestrian connections, widened sidewalks and public realm work that would integrate Moscone with Yerba Buena Gardens and adjacent retail.
Why it matters: Officials and neighborhood advocates framed the expansion as more than a convention center project. Supporters argued it will bring sustained economic activity and jobs, strengthen nearby retail and cultural institutions, and generate public‑realm improvements often lacking in the convention corridor. Several commenters pressed the project team for detailed pedestrian‑safety planning during construction and future operations; staff and the sponsor committed to coordinating mitigation measures and impact fees with the Central SoMa plan.
What proponents said: Andrew Robinson of the Yerba Buena Community Benefit District and others praised street‑level activation and public art opportunities. Kevin Carroll of the Hotel Council emphasized the project’s role in protecting local jobs and a tourism economy that employs thousands. The developer and city staff pointed to outreach spanning more than two dozen community meetings and to design revisions made in response to concerns.
Open questions and conditions: Speakers from senior‑housing and disability‑advocacy groups, and some neighborhood advocates, asked for a detailed pedestrian safety plan and clarified commitments for improvements to the playground and adjacent gardens. Staff told commissioners that some pedestrian improvements will be implemented directly by Moscone while others will be addressed through Central SoMa impact fees and related planning efforts; the EIR and entitlement hearings will return with more detail and conditions in August.
Procedural next steps: Staff said the EIR certification and entitlement hearings are scheduled in mid‑August; commissioners asked for specific follow‑up on bicycle circulation, business access to the Yerba Buena terraces and how the project will coordinate with planned street conversions (such as two‑way Howard Street) to improve pedestrian safety.
The informational hearing did not include a project vote; staff urged commissioners to focus follow‑up questions on construction staging, pedestrian safety, retail access, and the draft mitigation measures ahead of the forthcoming EIR certification hearing.
