Flood Mitigation isn't rocket science.

FM officials MUST implement urban development policies/regulations that address some basic facts:

1) Every river will periodically occupy its flood plain (that's what river's do...)

2) Flooding is an unavoidable consequence of living where we live

City officials must understand that engineered "solutions" can and do fail (there's always a bigger flood looming). Officials should implement policies which build community resiliency - develop resources to better predict and understand flood events, move people out of harms way, and ensure future generations don't repeat past mistakes.
