Restoring some of those areas can help offset the impacts of sea level rise, but it’s a big, complex and expensive job. 

   The North Bay area can play a large part in future efforts to recreate extensive natural wetlands to help protect the greater Bay Area from rising sea levels, says Letitia Grenier from the San Francisco Estuary Institute.

One tool in this restoration work, Grenier explains, can be re-using the sediment that is dredged from the floor of San Francisco Bay.
