This book was absolutely incredible. Everyone in the state of California needs to read this!!
It was the perfect blend of facts and stories, history and present, problems and solutions, despair and hope. Xia did such a great job composing this and you can tell it took years of work and hundreds of conversations with people throughout California. As someone who lives in one of the cities referenced in this book, this book was extremely personal. I learned things about my home that I never knew and now I look at the coast with new eyes. Our coast is degrading, how will we fix it? No matter what we do, the ocean *will* rise and we can never beat it’s magnificent power. It was infuriating to read about people just wanting to reenforce sea walls — which destroy the beach, are only a temporary fix, and are extremely costly — just to protect their property value. It’s a huge privilege just to own a house! It’s devastating to hear about Marin City and Alviso — low income, predominately non-white communities — that are constantly neglected and suffer the worst consequences. But there are so many solutions already in the works! Sea walls are being banned, dunes and estuaries are being restored, “living” structures are being built, managed retreat is starting to be taken seriously. This book is the perfect balance of “something is wrong” and “this is how people are fixing it”.
Notes:
* Every 1 foot of sea level rise pushes the coast back as much as the length of a football field (300 feet).
* If businesses continue as usual and global temperatures continue to rise, more than $370 billion in property could be at risk of coastal flooding by the end of the century.
* In a few more decades, 2/3 of the beaches in Santa Barbara, Los Angeles, Orange County, and San Diego will be lost to the sea.
* Pacifica is the most eroded coastal town in California — they represent what much of California will look like soon.
* It cost Pacifica $16 million to respond to the devastation caused by the latest El Niño in 2016 — out of their $36 million operating budget that relies mostly on property taxes.
* Historical erosion rates of Pacifica indicate a long-term average of about two feet per year being eroded from the coast. With projected sea level rise of about a foot and a half by the year 2050, we could expect the erosion rates to approximately double.
* In just the next 20 years, even if the sea rose only by modest amount, armoring the entire state of California could cost home owners and taxpayers more than $22 billion.
* Choosing to protect homes, roads, and other critical infrastructure behind the seawall is a direct choice to sacrifice the beach in front.
* The Embarcadero in San Francisco safeguards more than $100 billion in businesses and buildings. There would be no port of San Francisco without this waterfront, which moves billions of dollars in goods and services in and out of the bay. There would be no San Francisco without this enormous seawall.
* The ferry building, were all transportation lines and the city come together, could flood every day if water rows three more feet — an extreme scenario that some study said could arrive before 2050. A report in 2016 also found that it wouldn’t take much more than a moderate sized earthquake to liquefy the soil holding up this fall.
* Without reinforcement, the Embarcadero could also slum into the fill in an instant. Updating the seawall would cost at least $2 billion, likely many billions more. But the cost of doing nothing would be even greater: studies estimate that on the northern end of the waterfront alone damages from earthquakes and flooding could total as much as $30 billion.
* “Never start a conversation with sea level rise as what we learned. Start the conversation with: ‘what do you care about? What do you want your community to look like?’ Uncovering the problem together and having time for the process to evolve is really important.” — Lindy Lowe, port of San Francisco’s resilience officer
* Project designs for a bigger seawall are nearly completed and construction is expected to begin in 2024.
* They are working on ways to make the sea wall more textured, reef-like habitat — a living seawall — with bumps and ridges that could support rock, weed, oysters, herring, and other rock-shore species.
* “Resilience is often about making sure we are strong enough to not be changed, but what if we should change? We’ve seen increasing gentrification and disparities in wealth. We’ve seen the cost of housing in the coastal zone go through the roof, and we’ve seen exposed, impoverished political system that in many cases is driven by power and vested interest, as opposed to larger interests of society, and the community. So my mind, we need to figure out how to adapt — but it’s deeper than that. So as a first step, I think we need to acknowledge and recognize and remember that social institutions are human created artifacts. They’re not rooted in some natural order. All of these debates that we’re having along the property of the shoreline: that’s really rooted in the original colonialism, and the taking of land — by the sovereign, and then passing it from the Spanish government to the Mexican government to the US government —and establishing the property lines that we are now fighting about up and down the coast.” — Charles Lester, lawyer, and political scientist, who was on the Coastal Commission
* Sea level rise means you also get salt water intrusion in the ground water from below, causing communities not immediate to the water like Marin City face flooding.
* Lower income communities of color are five times more likely than California’s general population to live within half a mile of a toxic site that could flood from rising water.
* It’s important to know that managed retreat is not a goal in itself. Ensuring that the community is safe is a goal. Providing social and environmental justice is a goal. Providing coastal, habitats and public open space is a goal. Managed retreat, many researchers have clarified, is simply one way to help a community achieve those goals.
* Even if the entire world stopped emitting carbon dioxide tomorrow, the sea will continue to rise for decades. Due to all the planet-warming gases already released in the atmosphere, the best and worst case scenarios look roughly the same between now and 2050. (imagine putting the engine of a speeding ship in neutral) there is still time to stop these shocks in the climate system after 2050 — every inch makes a difference and our actions today will determine how livable our planet will be in the final decades of the century.
