For more information about the making of these maps and the NASA data used to create them visit: About Flood Maps. Please set the map to 1 meter for more realistic views. 1 meter is the maximum height predicted for the Bay Area due to Global Warming. (1 meter = 3.2808399 feet) This shows average sea level rise in the shaded color, it does not show what flooding results would look like during a flood event. According to the International Panel on Climate Change Summary for Policy Makers out in November 2007, we have already seen a 1.75 inch average global sea level rise since 1993. If development is allowed on the flood plain there we will face continued flooding, blocking of our water table recharge areas, more cars (and more greenhouse gas emissions) leading to increased global warming. This is a policy of poverty and suffering. There is no acceptable level of risk.
