The bursting of the housing bubble wreaked havoc on cities across the United States causing widespread blight in once-thriving community economies. Foreclosed, abandoned and condemned homes continue to pockmark neighborhoods and communities, adding to the vacant lots of populous but affected cities like Philadelphia. The Mayor’s Office of Philadelphia approximates that there are nearly 40,000 vacant lots throughout the city of brotherly love, about 74% of which are privately owned, making them virtually inaccessible to rehabilitation. But the city has a strong drive to amend these conditions. With organizations like DesignPhiladelphia’s “Not a Vacant Lot” and the city’s Redevelopment Authority, some of this land is being put to good use.
