Since nature does not stand still, man-made landscapes are distinguished from buildings and artworks by the dimension of time, and taking the long view is what landscape architecture can contribute to urbanism. In two impressive industrial remediation projects, one in London's Greenwich Peninsula and the other in Bordeaux, Michel Desvigne shows a plan that extends over intervals of 10, 25, and 50 years. Another project that takes the long view is the Fresh Kills Lifescape, a conversion of the Staten Island landfill to parkland (at right). Instead of a conventional master plan, James Corner of Field Operations has designed a strategy for the next 30 years. Not simply phasing-in an extremely large (2,200 acres) site, it is a dynamic approach related to hydraulic systems, progressive planting, and soil remediation. This is landscape seen not as artifact or as artwork, but as process. Incidentally, Corner's earthwork monument, on the site of the World Trade Center debris, may turn out to be the 9/11 memorial that New Yorkers are waiting for.
