Even though Dan Hoover’s been surveying the same stretch of San Francisco’s Pacific coast for 15 years on his ATV, it never looks the same. In summer it’s wider and in winter narrower. With El Niño the beach will erode more than ever.
Scientists discover why the Bay Area’s two populations of endangered salt marsh harvest mice differ, and it’s partly due to sea level change.
Can tides and waves move sediment placed in the shallows onto wetlands? The Army Corps is experimenting with how to do it.
Scientist and coastal engineer Kris May shares her views on global versus Bay Area climate experiences in 2023, and the Fifth National Climate Assessment.
Like Russian dolls, Bay Area preparations for sea level rise finally began fitting together this fall.
The futuristic radio play Forever Wave explores a San Francisco remade by 200 feet of sea level rise. The narrative floats in and out of the thoughts of more than 60 characters over 24 hours.
Ten months after the Port of San Francisco lowered 288 experimental tiles into the water, these bio-friendly seawall surfaces are already crawling with crabs and covered in kelp. This August, researchers are finally getting a good look at all the tile types in their experiment, which range from large to small, and from bumpy to smooth, and which were hung from the waterfront at three different locations and tidal elevations in October 2022.
A little-known tenet of California law may play a key role in preserving the state’s beaches—and the public’s access to them—as sea levels rise. “In a lot of places, the public trust boundary will move landward,” says Awbrey Yost…
Regional agencies made splashy headlines when they released a joint study on the likely cost of protecting Bay Area shores from rising seas: $110 billion. But the top-line number didn’t offer much insight into the complexities. A new inventory and map from the same agencies is much more revealing.
In San Mateo County, new planning guidance may help cities account for rising seas when approving new developments. OneShoreline’s proposals are stricter than current requirements from federal, state, and local agencies, but those are also evolving. “The intent is to go where we already see regulators are going,” says Makena Wong, a project manager.
The region is obsessing over beach-building. Whether it’s a degraded salt marsh in downtown San Rafael or a sliver of wetlands near the old San Francisco shipyards, local practitioners are adding beaches as nature-based buffers against waves and rising seas to adaptation projects around the Bay.
Coastal erosion in Pacifica, drought in Brentwood, fires in the North Bay, flooding in Union City, and urban heat in San Jose. Anissa Foster takes us on a revealing virtual tour.
