The recession in Flint, as in many old-line manufacturing cities, is quickly making a bad situation worse. Firefighters and police officers are being laid off as the city struggles with a $15 million budget deficit. Many public schools are likely to be closed.

“A lot of people remember the past, when we were a successful city that others looked to as a model, and they hope. But you can’t base government policy on hope,” said Jim Ananich, president of the Flint City Council. “We have to do something drastic.”

In searching for a way out, Flint is becoming a model for a different era.

Planned shrinkage became a workable concept in Michigan a few years ago, when the state changed its laws regarding properties foreclosed for delinquent taxes. Before, these buildings and land tended to become mired in legal limbo, contributing to blight. Now they quickly become the domain of county land banks, giving communities a powerful tool for change.

Indianapolis and Little Rock, Ark., have recently set up land banks, and other cities are in the process of doing so. “Shrinkage is moving from an idea to a fact,” said Karina Pallagst, director of the Shrinking Cities in a Global Perspective Program at the University of California, Berkeley. “There’s finally the insight that some cities just don’t have a choice.”

While the shrinkage debate has been simmering in Flint for several years, it suddenly gained prominence last month with a blunt comment by the acting mayor, Michael K. Brown, who talked at a Rotary Club lunch about “shutting down quadrants of the city.”
