Port looks to bolster San Francisco shorelines against rising tides

Streets and buildings along San Francisco’s Embarcadero — including the iconic Ferry Building — could eventually be raised up to 7 feet, according to a sweeping draft plan unveiled Friday that would spend an estimated $13 billion to defend The City’s urban waterfront against rising seas and flooding.

The massive infrastructure scheme, spearheaded by the Port of San Francisco and the U.S. Army Corps of Engineers, sketches out potential measures for the 7½ miles of bayfront land under the port’s control.

The City’s waterfront would remain where it is currently. The levels of protection vary by location.
