One more thing, here's what the law says:
From Idaho Code 50-2018 (10) "'Urban renewal project' may include undertakings and activities of a municipality in an urban renewal area for the elimination of deteriorated or deteriorating areas and for the prevention of the development or spread of slums and blight, and may involve slum clearance and redevelopment in an urban renewal area, or rehabilitation or conservation in an urban renewal area, or any combination or part thereof in accordance with an urban renewal plan."
Credit that to Sharon Ullman who added that to the 2007 Fairview/Main poll thread.

Finally, it seems the majority of this law was enacted in 1965. It's unclear to me how much of it as been amended. Like I said, the legislature is being lazy if they resort to ban them all. That law in its entirety is pretty lengthy and takes a long time just to read, let alone figure out how to improve it.
