11. Key Findings American Institute of Architects Nationwide Voter Survey 2009 Thinking about energy in the United States -- how would you characterize the energy situation right now in this country? Would you say that: 2009 2007 We are doing well 4 5 We are doing okay 17 19 We are having some problems 29 34 We are on the verge of a crisis 28 28 We are in an energy crisis 21 13 COMMENT : Voters see the energy problem more negatively than they did two years ago, but not by large margins. Doing “well” and “okay” combined has declined from 24% to 21% and “verge of a crisis” combined with “in an energy crisis” has increased from 41% to 49%. All responses of a negative nature total 78% indicating that Americans believe that the energy situation is a problem of one degree or another.

70. Conserve Water “ The reality is that, over the 30-year life of a typical home mortgage, there is a 26% chance of a flood that exceeds the 100-year standard. Over the course of a century, there is a 63% chance that a flood greater than the 100-year standard will strike, a 26% chance of two such floods, and an 8% chance of three such floods. So it is hardly a statistical surprise that the upper Midwest suffered 100-year floods in 1993 and 2008.” WSJ Article 4-30-2011

71. Conserve Water Japan and the Netherlands, for example, protect against river floods to a 2,000-year standard for densely populated areas and a 200-year standard for rural zones.
