Temporary Takings and the Adaptation Dilemma

Current law penalizes adaptation measures because of the risk of takings liability.

Is it unconstitutional for the government to build a levee that reduces the risk of urban flooding but diverts the water to nearby farmlands?  The answer could be yes, unless the government pays for flood easements on the rural lands.
