San Francisco Rising to Threat of Swelling Seas

The fog of uncertainty cast by rising seas is starting to lift from $25 billion worth of public projects planned in San Francisco.

The City by the (rising) Bay, where bayfront shorelines will continue to experience worsening high tide flooding, where the nearby international airport is among the nation’s most vulnerable to floods, and where Pacific Ocean shoreline erosion could be accelerated by sea level rise, has adopted a first-in-the-nation approach to assessing potential infrastructure risks posed by rising seas.

The new guidance, which includes a simple project checklist, will help officials incorporate sea level rise into decisions about building and upgrading everything from pipes to police stations to streets. Seas have risen 8 inches since industry started burning fossil fuels, although long-term ocean cycles have temporarily spared the West Coast from some of those impacts in recent decades. Two or three more feet of sea level rise is forecast globally this century.
