Tackling the rise in SF Bay levels

Climate change-induced sea level rise will have a similar effect on San Francisco Bay, leaving planners, taxpayers, and environmentalists with a difficult problem in how to manage the rising Bay. The Chronicle covers some interesting and highly speculative ideas entered in a recent contest:
Once they would have been the stuff of science fiction: shimmering levees of
water that shield cities, or laser beams slicing across water through the

In fact, these are two of six winners announced Tuesday in a
design competition that responds to a real-life threat - scientific projections
that in the century to come, the sea level of San Francisco Bay could climb 55
inches beyond today's high tide.
"We need to rethink how we build along the
shoreline, but we didn't have the answers," said Will Travis, executive director
of the San Francisco Bay Conservation and Development Commission, which
organized the competition. "So we decided to cast the net for ideas."

The ideas can be seen here. I skimmed through a few, and any solution is going to be expensive. This is something that both San Mateo and Santa Clara Counties are going to have to deal with, soon.

It would be interesting to see how much could be saved if aggressive action on climate cut the Bay level increase in half.
