Detroit has numerous neighborhoods suffering from urban decay, consisting of vacant properties resulting in low inhabited density, stretching city services and infrastructure. These neighborhoods are concentrated in the northeast and on the city’s fringes. The 2009 residential lot vacancy in Detroit was 27.8%, up from 10.3% in 2000, with the population continuing to shrink and foreclosures that exacerbate the problem. An estimated 20 to 30 percent of lots are vacant. A 2009 parcel survey found 33,527 or 10% of the city’s housing to be unoccupied, but recommended that only one percent or 3,480 of the city’s housing units be demolished. In 2010, the city began using federal funds on its quest to demolish 10,000 empty residential structures.
