Climate Central’s “Picturing Our Future” makes it clear that sea level rise will flood large areas of SF.  If San Francisco is going to survive, we must act now and work with nature instead of against it.  How do we work with nature in our mitigation efforts?  We build horizontal berms around the coasts, plant seagrass meadows and destroy urchin barrens to restore the kelp forests, create rain gardens and mini-polders, restore beaches, and elevate housing. 

At the same time, we need to alter a bunch of our infrastructure or move it uphill.  This infrastructure includes our wastewater treatment plants, a lot of transportation, the airport, and our water supply.  Sea level rise is here and increasing daily.  We can’t wait any longer; the mayor and city government must act now.
