Sustainable Urban Islands
A concept towards the future development of the earth’s coastlines as land suitable for urbanization becomes scarce and as the effects of global warming on sea levels and the coastal interface become apparent. It is the utilization of new and emerging technologies,
i.e. highly advanced materials and methods in combination with the techniques of the oil platform and the oceanic wind turbine farms to create self contained energy efficient islands of growth.
These structures would use the latest in solar generating materials to augment other sources in their goal of self-sufficiency in power and the latest in de-salinization in order to achieve the same for their water consumption needs. They would be capable of treating and disposing of a majority of their waste in an environmentally friendly manner.
They would also provide the least resistance to tidal action and would not be vulnerable to the destructive sea forces such as tidal waves and erosive turbulent storms as lower manmade islands. The strength of the construction, their height above the mean high tide and the design of the anchoring to the sea bottom, their footings, will ensure the stability of the construction.
Access would be provide by at least three modes of transportation. Small electric vehicles would run along the connecting causeways to the shore where an interface with a shoreline transit terminal provided access to rapid transit train trains and buses.
Boats with the latest hybrid diesel electric marine propulsion systems would be a second means of access. Seaplanes and marine helicopters would be a third means of access.
This is a systems concept where prefabricated components, i.e. integrated panels and structure, can be mixed and matched to create endless variants on a theme. Further, the components would be available in a many sizes allowing for changes in the scale of the development.
The concept allows that the relationship of each vertical element to the shore line can vary and the patterns of development can also vary in response to the particular coastal shapes and elevations.
The concept may be used in river developments as exist in many urban areas both along the coast and inland. They could for example extend the island of Manhattan into the Hudson River or spring from the lower area recently inundated by the hurricane Sandy. Traditional harbor areas such as along the Jersey shore could anchor such developments. See the illustration that shows two towers at the foot of 59th street and the Hudson River shoreline.
