A new report by the state agency responsible for protecting the San Francisco Bay shows thousands of acres of shoreline may be in danger of flooding in coming decades if some climate change predictions prove correct.

The April 7 draft report of the San Francisco Bay Conservation and Development Commission includes maps of the Bay shoreline showing broad swaths of low-lying areas likely to be flooded by mid-century, and even greater areas by 2100, by rising sea levels due to global warming.

The areas include sections of the Bay shoreline in San Francisco and at the San Francisco International Airport, Alameda, Oakland, Berkeley, Richmond, Redwood City, Hayward, Fremont, San Jose, Sausalito, San Rafael, and north to the Petaluma and Napa rivers as well as east to Suisun Marsh, Grizzly Bay and Honker Bay.

“We hope this information will help government agencies, property owners and the general public better understand the impact of sea level rise along specific parts of the Bay shoreline,” commission executive director Will Travis said in a written statement.
