Sinking Bay Area could exacerbate risk of flooding in years to come

 

Researchers say that sinking land in the Bay Area will increase the risk of flooding predicted for 2100 due to rising sea levels.

Several locations, such as Treasure Island, Foster City and the San Francisco Airport could be at risk, according to researchers from University of California at Berkeley and Arizona State University.

These sinking land areas could nearly double the impact of flooding from sea level rise alone.

Original estimates predicted that 20 to 160 square miles of the San Francisco Bay could be flooded by 2100, based on the rate of sea level rise.

Taking into account subsidence, or the gradual sinking of land, researchers say this number could increase to between 48 and 166 square miles.

Even then, the number offered by scientists is only an average. If there are king tides, storms, or other scenarios of peak water-level change, scientists say the risk of flooding could be even higher.

"The ground goes down, sea level comes up and flood waters go much farther than either change would produce by itself," said author Manoochehr Shirza, a member of NASA's sea level change planning team and a former UC Berkeley postdoctoral fellow.

Researchers say city planners and local officials will use their findings to plan for the future and improve emergency response strategies.

Between hypothetical flooding in 2100 and the drug dealers with loaded AR-15s living in RV's in my neighborhood, I'm more worried about the latter.

If the water rises and the land sinks, common sense tells us that would lead to more rapid flooding. But is the land actually sinking? Did the land sink in the San Francisco earthquake or did it rise or was there any change in elevation of the land or only a large horizontal movement, northward on the west side of the fault and southward on the eastside of the fault?

Why do they high tech industries insist on building here?

I'm so glad we're going to fix our "housing imbalance" by building 10,000 housing units over land that will be flooded in a generations time. Way to go Mountain View City Council. You guys are so slick, nothing gets by you! ;)

Everyone should by a boat.

This city council has the chance to go down in history as the worst in city history. Not only did they give away our water rights for pennies on the dollar, they approved construction of thousands of new homes that will soon be flooded. These historically bad decisions will hurt Mountain View for decades and centuries to come.
