John King, urban design critic for the San Francisco Chronicle, explores how San Francisco’s Ferry Building mirrors the city's evolution and broader urban American challenges in his book new "Portal." More than a historic transportation hub, the Ferry Building's journey from glory to neglect and resurgence symbolizes San Francisco's shifting narrative. King delves into the interplay of preservation, development, and adaptation, while addressing existential threats like climate change and seismic risks. He reveals how a single landmark encapsulates a city's history, growth, and future uncertainties.
