There is concern that some cities along San Francisco Bay are sinking at an alarming rate, according to a new NASA-led study examining the shorelines.
Scientists used satellite radar to track more than 1,000 miles of California’s coast, pinpointing hot spots.
The study found four places in the Bay Area that are sinking the fastest: San Rafael, Corte Madera and Foster City, along with Bay Farm Island in Alameda, which is located next to Oakland International Airport. The land in those areas is subsiding at a rate of more than 0.4 of an inch per year.
Even though the changes are small, it can have a major impact on local flood risk.
NASA predicts the local sea levels could rise more than 17 inches by 2050. That's more than double the regional estimate of 7.4 inches.
