Siting Shrinkage: Comparative Urbanism in Shrinking City

URBAN DESIGN STRATEGY: The Green Archipelago
The Green Archipelago is an urban design concept used to describe ways urban areas actually function and how they should be conceived. The manifesto was introduced in 1977 by Oswald Mathias Ungers and Rem Koolhaas after a Cornell summer program in Berlin. This alternative model of urbanism challenged Urban Renewal and instead embraces depopulation in Western cities, imagining them as archipelagos of urban islands in seas of greenery, incorporating nature, agriculture, and infrastructure of contemporary suburbia. The idea is to weed out substandard areas and intensify fragments worth preserving. The substandard parts are left to be reclaimed by nature, while the intensified islands form an archipelago within the green “sea”.
Berlin was used as a testing ground for this alternative model of urbanism. When the manifesto was written, the Berlin Wall enclosed West Berlin (1961-1989), cutting it off from surrounding East Germany. Because of these existing political conditions, Berlin needed to develop strategies for the controlled decrease of its density to maintain overall urbanity.
The manifesto lists steps of actions that can be applied to other cities facing depopulation. However, because each city is unique, the approach must accommodate differences. When applying this to the city of Buffalo, NY, a difference is that becomes evident is that Berlin’s population was more culturally homogenous. Buffalo’s urban fabric is divided by Main St., separating the city into racially distinct neighborhoods. According to 2010 demographics, Buffalo is 50.4% White, 38.6% Black, 10.5% Hispanic and 3.2% Asian. Ranked second in the country for having the most vacant properties per capita, it has over 10,000 vacant homes. The vacancies in the city coincide mostly with poor, Black neighborhoods, many of which are adjacent to families with deep roots in Buffalo’s history. To apply the Green Archipelago’s methods in their purity, much of the entire East Side of Buffalo would be abandoned, and left to return to nature with remaining inhabited housing sprinkled in between. One cannot ignore the racist undertones to this action. It also does little to address the associated homelessness, crime, poverty, and general immobility that could result from the process. Remaining citizens in the area would be absorbed into a nature grid of farmland or parkland which the manifesto proposed would stimulate new forms of tourism, “such as hunting safaris.” The manifesto does propose that the Nature Grid accommodate modern infrastructure including connective transportation, super-markets, cinemas, churches and banks which may help to decrease isolation and increase opportunity in those areas.
The major distinctive issue of Berlin was the barrier of the Berlin Wall-limiting access. When applying the Green Archipelago to another city, borders must be considered differently. The city of Buffalo borders several suburbs to the north, east and south, a large source of down-town labor force and weekend event-goers easily accessed by roads and highways. To the west, Buffalo has an international border: the Peace Bridge to Canada, as well as an underused waterfront--currently industrial and recreational--with the attraction of Niagara Falls just to the north. Perhaps the archipelago could extend past the borders of the city and even into another country. Also, a city’s economy would need to be addressed in the design. In Buffalo, while manufacturing jobs are decreasing, educational and health services jobs are rising. These campus layouts translate easily into a “city within a city.”
Buffalo represents the American post-industrial Shrinking City. Its population peaked in the 1950’s at 580,000 and has since declined to about 259,000 people. Its current density is 7,205.8 people per square mile. Buffalo already has a robust park and park-way system designed by Olmsted. This makes absorbing vacant parcels into a nature grid a logical approach. Some of these ideas are already happening, manifesting in urban farming on vacant parcels such as the (Massachusetts Avenue Project, Urban Roots Cooperative Garden, Curbside Crofts, and Queen City Farm), large industrial relics left to be consumed by nature, and strategic demolition of blighted housing.
Some challenges for the Buffalo Green Archipelago would be the conversion of existing vacant land to productive use. Since Buffalo supported heavy industry for many years, much of the land is contaminated brown field sites that would be toxic for traditional farming. There are solutions to this; costs and benefits would have to be considered and alternative uses and opportunities should be explored. Unique characteristics of the city could be employed within the archipelago. Boasting eight colleges and universities, these could function as islands of their own, connected by an education infrastructure network so that students could share facilities as the city downsizes, and the general population could have increase access to supplemental education, culture and events on campuses.
The proposal identifies within existing networks and fabrics areas of vacancy and proposed demolition. Ideal areas are then absorbed into the park and parkway system forming a nature grid around urban islands. The urban islands were selected similarly to the original manifesto. Unique groupings of buildings that also support a strong identity or embodies values of the city were identified. These islands would be nurtured with stimuli and architectural intervention, while their surrounding areas might be left to naturally decay over time. As the city’s population shrinks, more functions can be rerouted to these buildings-such as libraries, gyms, temporary markets and shelters. Part of the process of the Urban Archipelago design strategy of intervention and completions might also be disassembly and reassembly- combining activities into fewer buildings, making some mobile and traveling rather than fixed, and rethinking times of operations of activities. The plan allows the city to react to change over time and maintain urbanity as population continues to decrease.
