Troy with 86,000 residents is running out of space and residents are miffed. Kurt Metzger, director of the Center for Urban Studies at WSU, said Troy has some built-in safeguards that will help it avoid the dwindling tax dollar situation that plagues some older suburbs. "Troy doesn't suffer from the same kind of issues that many other built-out suburbs have, such as a diminishing income," said Metzger.
