using highways as flood channels is a complete no-no until we started to bring out examples like the glasgow flooding and said for most of this event, the highways acted as flood channels. the interesting thing when you start to look at urban flooding, you start to learn some very important lessons. first is that water flows downhill. secondly, it accumulates in low spots. in the uk, it's very interesting what you find in those low spots. first of all, you find that's where the low income houses, that's where the poor people live, the people who have no say really in what goes on in the community. so i was really pleased you make the point about environmental justice. the second thing you find out in the uk it's almost always where we put our emergency services because the land is cheap. your fire departments, the ambulances, all that disappears in the first half hour of the storm. >> we use earthquake faults for that. >> okay, but i like the idea of the pilot project because people don't have to commit themselves so much. you get them working on the pilot project and then you expand it. >>
