A new island: Hadid unveils radical plan for Bilbao:

The British-Iraqi architect Zaha Hadid has presented radical plans for the city’s neglected Zorrozaurre peninsula, part of a redevelopment that would see it converted into an island.
Once a crucial part of the port, the peninsula, in the estuary of the river Nervión, had been left to decay. With only around 450 people living there and a few small industries left, it seemed to have no part of Bilbao’s glowing future.

While urban renewal and reuse is certainly admirable, a quick google search shows that not all who live on the Zorrozaurre peninsula share Hadid’s vision. See Proyecto Zorrozaurre, Zaha Hadid. Bilbao for a exhaustive series of images of Hadid’s plan and Zorrozaurre Master Plan @ The Pritzker pdf. The Forum for a Sustainable Zorrozaurre is highly critical of the proposed plan (see Creating an Eco-Community In A Post-Industrial Wastelandfish pdf).
Below is a map of the Zorrozaurre peninsula:

The Zorrozaurre peninsula seems to be a cross between the High Line in Manhattan and Hog Island in Philadelphia. While Zorrozaurre is mostly industrial wasteland, not all of the Zorrozaurre peninsula is wasteland; some parts of the Zorrozaurre peninsula are quite picturesque.
What would have been really interesting is if Hadid had inverted the peninsula by using what ills the area most, decaying industry, as a tool for reclamation. One thought which struck me right away is the audacious idea to transform the Zorrozaurre peninsula into a giant filter; a filter which would clean both the river and the surrounding industrial wasteland. Hadid is already going to raise the base level of the new buildings; think of the possibility of living over a natural filter, be it a sponge or a series of reeds. As water passes through the city-filter it is slowly cleansed.

Thus the city would act as a massive reparative device, slowly cleansing the countryside of toxins which past industry and citizens inflicted upon the land. Now this massive industrial-ecological complex doesn’t necessarily require Archigram-type installations and technology. However, those 500 citizens who live in the Zorrozaurre peninsula already inhabit a territory which is the figural negative space of a massive industrial complex which has run its course. It would be all too fitting to use this negative industrial space as an archaeological foundation in order to clean the ills of that decayed industry.
