Most of the time historic preservation is in the news, it is the result of efforts to save a historic property from demolition. This important focus on struggles to save individual buildings often prevents us from seeing that historic preservation is a factor in the economic development of the city. Are you aware that in the past 20 years more than $1.5 billion has been invested in converting historic properties to contemporary use, ranging from housing to hotels to cultural facilities? And that investment has also produced more than 55,000 jobs. Even more remarkably, most of this has been accomplished through private investment with relatively little public funding. Here are some recent examples of historic preservation as economic development in four specific areas that are important to the future of Philadelphia.
