California ports heard a report that the cost of defending the San Francisco Bay from sea level rise could cost $110 billion while the City of San Francisco may need an additional $13 billion to defend itself.
Even more ominously Brian Garcia, Warning Coordination Meteorologist, National Oceanographic and Atmospheric Administration (NOAA) noted that ice sheet losses in Antarctica and Greenland will add 13-14 feet to global sea level rise and is a certainty to occur. The only question is how soon.
The reports were presented at the Storms, Flooding & Sea Level Defense 2023 conference, a co-production of the Propeller Club of Northern California (PCNC) and the Society of American Military Engineers (SAME).
Rachael Hartofelis, Project Manager, Metropolitan Transportation Commission/ABAG and Dana Brechwald, Assistant Planning Director for Climate Adaptation at the Bay Conservation and Development Commission (BCDC) discussed findings of the report: “Sea Level Rise Adaptation for S.F. Bay Area Could Cost $110 Billion.”
Warner Chabot, Executive Director, San Francisco Estuary Institute, urged developing a strategy to pay for the $110 billion. He also urged more nature-based shore protections, that should include nearshore reefs, beaches, tidal marshes, green stormwater infrastructure and more.
