A dreamy bayside community is facing a tough reality as rising sea levels threaten to upend its waterfront culture and economy. Officials are asking the public to be part of the solution.
What’s happening?
As the Marin Independent Journal detailed, city consultants delivered “dreary news” at a community meeting in Sausalito, California. John Gibbs, an urban designer with the firm WRT, explained that the waterfront community could experience disruptions due to 10 inches of sea level rise over the next 25 years, in addition to the 5 inches it has seen since 1975.
The consultants zeroed in on zones they identified as particularly vulnerable, including Swede Beach, where they expect waves to eventually break beyond a promenade and flood buildings; New Town, where the city’s main waterfront thoroughfare of Bridgeway is only 12 feet above sea level on average; and Marinship, whose tourist attractions include World War II-era shipyards.
Why is this important?
Sea level rise is occurring as the climate warms because ice glaciers are melting and our oceans are absorbing more heat (a process called thermal expansion). Rising temperatures, driven higher primarily by heat-trapping pollution generated by dirty fuels, have also caused extreme weather events to become more deadly and dangerous.
For waterfront communities, this leads to more destructive storm surges. Gibbs explained that Sausalito’s bay levels could be 3 feet higher by 2100, meaning surges could exceed 6 feet.
What’s being done about this?
Sausalito revealed its Shoreline Adaptation Plan at the community meeting in September. Ultimately, while mitigation measures can be expensive, they can make the difference between disaster and preservation. The city’s “toolkit” suggests a multifaceted approach that involves sea walls, flood barriers, elevated infrastructure, and floating structures…
