Launching big public initiatives has never been easy in Minneapolis, where a weak mayor-strong council system forces every new idea to be subjected to the will of dozens of elected officials and bureaucrats before becoming reality. The gridlock has particularly affected the arts, since nearly every bold proposal eventually falls victim to the endless bickering of the committee process. The city’s current mayor is hoping to galvanize support for any number of public design projects to complement an ongoing downtown boom, but wary of the failures of past administrations, even his pitches are vague and seemingly designed to accomodate the nitpicking that is certain to follow.
