Philadelphia currently has the 5th highest population density of any
major US city. However, over 72% of the metropolitan population of
Philadelphia resides outside of the city limits (Philadelphia County).
Though Philadelphia's population decrease over the last 50 years has
been considerable (currently 70% of the 1950 population), as a
percentage change it pales in comparison to the intense growth
experienced by the surrounding suburbs where the population has
increased more than 220% over that same period of time.
Despite the numerous clear and present vacancies throughout,
Philadelphia County remains dense in terms of its overall population.
The broader metropolitan area as well – as defined the US census –
continues to densify. If population density alone is not an accurate
barometer of the quality of an urban fabric, what then differentiates
these two organizational structures?
Philadelphia County proper suffers from a pervasive absence of urban
programs and a deficiency in the urban infrastructure necessary to grow
and sustain a vibrant 21st century urban ecology.
Filling the numerous voids of Philadelphia with conventional park /
garden / recreation programs will superficially improve the urban fabric
of the city, but such a move alone will not structurally affect the
fundamental deficiencies of the metropolis.
The essential questions that this project aspires to answer are: “How
can Philadelphia generate the multiplicitous urban programs necessary
to take advantage of the social, cultural, economic and institutional
infrastructures already present at localized moments within the larger
conurbation?” and, “How can Philadelphia use these infrastructures to
grow and sustain a vibrant 21st century urban ecology?”
Philadelphia does not need a conventional master plan or
formal reconfiguration. As the archetypal post-industrial American
city, Philadelphia needs a tactical operative system by which to
navigate the shift from the collage urbanism of the 20th century to the
EMERGENT URBANISM of the 21st.
