The purpose of the ResilientCity.org Design Ideas Competition is to stimulate thinking and discourse about how to increase the resilience of our cities as we move into a century where our cities will be subjected to the combined environmental and economic impacts of Peak Oil and Climate Change.

crisis. With large areas of Detroit abandoned and left to decay its time to re-evaluate the fundamental
structure of the city alongside recommendations for a new denser suburban grain to create a true resilient city.
As a starting point we have asked ourselves the simplest of questions; can we turn these abandoned parts
of the city to the advantage of all and instil a shift to localised urbanism and sustainable living post peak oil?
In answer we believe we can – by giving back swathes of land within the city to urban agriculture, bio fuel
crops and renewable energy resources such as solar farms. The subsequent reduced city area available for 2009
residential use enables the opportunity for the intensification and restructuring of the remaining suburban areas

how they want to live, whether to redevelop their plot of land on their own, or perhaps with a neighbor, or maybe
a developer, or to keep the big house and all the land. Broad choice of accommodation is at the heart of our
proposal to foster diverse social sustainability. It would be naïve to suggest successful regeneration by
forcing everyone into high density apartments.

We appreciate this brief submission is part of the starting point on a issue which
needs much more research, trial and error, before a workable solution is
found. Therefore this paper can only hint at a suggested direction in
relatively simplistic terms with some broad assumptions made.
