Sea-level rise action needed?

Though California has done more than most coastal states to prepare for rising sea levels, experts warn efforts need to be redoubled.

Former Gov. Arnold Schwarzenegger signed an executive order in 2008 mandating that the California Resources Agency and other entities study the possible effects of sea-level rise. The order also required state agencies to take sea-level projections into account when planning future projects, according to SFGate.com. But the executive order does nothing to address existing communities and shorelines at risk, and no single state agency is currently in place to oversee future management efforts like new levees, raised seawalls, expanded wetlands and improved drainage systems.

Projections have indicated hundreds of square miles of the Bay Area are in danger of flooding by 2050.
