California’s Legislative Analyst’s Office (LAO) warned this week that the state can’t afford to delay efforts to deal with sea level rise flooding because of the Covid-19 pandemic.
In a report titled “What Threat Does Sea-Level Rise Pose to California?”, the LAO said: “While the coronavirus disease 2019 (Covid-19) pandemic and resulting economic impacts have rightly drawn the focus of the Legislature’s and public’s attention since March 2020, other statewide challenges continue to approach on the horizon. Among these are the impending impacts of climate change, including the hazards that rising seas pose to California’s coast.”
Report authors quote scientific estimates that California could face a half-foot of sea level rise by 2030 and up to seven feet by 2100. The threat posed by sea level rise could be amplified by storm surges, exceptionally high king tides that occur in the fall, and El Nino events.
Many coastal communities are already experiencing the negative effects of sea level rise and the situation is only going to get worse. Cities and towns are dealing with nuisance flooding, beaches are eroding, cliffs are collapsing — often carrying homes with them — and public infrastructure is being wrecked or overwhelmed. Natural resources, water supplies and entire economies are also at risk.
The report predicts that California will see up to $10 billion worth of property underwater by 2050 and up to an additional $10 billion worth of property inundated during high tides. When sea level rises four feet, 28,000 socially vulnerable residents in the San Francisco region alone could experience daily flooding. Furthermore, by the end of this century, up to two-thirds of the state’s beaches could be completely eroded away.
LAO officials said in the report that they recognize the burden the pandemic is placing on government and the economy. “However, given the significant threats posed by sea level rise in the coming decades–and the additional public safety and economic disruptions that will result absent steps to mitigate potential impacts –the state and its coastal communities cannot afford to defer all preparation efforts until economic conditions have fully rebounded from the recent crisis,” they said. They recommend that the government undertake activities to address the threat posed by sea level rise that require little funding, such as continuing to draft plans, meet and share information.
In the U.S., federal, state and local governments are bending under the enormous administrative and economic burden posed by the Covid-19 pandemic. The California LAO’s insistence that efforts to address sea level rise continue even in these troubled times is on the mark. The fact that regardless of the pandemic, global warming continues to cause sea level rise, putting hundreds of billions of dollars worth of real estate and critical infrastructure at risk. Protecting property and infrastructure isn’t cheap and it can’t be accomplished overnight. Letting down our guard now, will have grave consequences in the future.
All coastal communities and real estate owners and buyers need to heed the California LAO’s warning.
