Detroit, Highland Park, Pontiac and other Michigan cities face losing millions of dollars in federal aid to reclaim and rebuild neighborhoods riddled with abandoned and foreclosed properties unless they can spend it all in the next nine months. The cities already have had two years to put the money to use. Now, a February deadline looms for the State of Michigan’s Neighborhood Stabilization Program (NSP) to spend a $224-million grant from the federal government or return it. But many of the cities that are part of the program — Detroit in particular — have been extraordinarily slow to spend what was the single largest grant awarded under the federal program in 2010. As a result, Michigan was just one of two recipients nationwide to miss a February deadline to spend half of the funding. Three months later, the program still hasn’t hit the halfway mark.
