Treasure Island is a man-made island, originally built for the World Fair, subsequently it became a Navy base, and has since gone through a number of different development plan attempts. We seem now to have a plan that has broad acceptance, dealing with the clean-up of the contamination on the island and delivering a model for sustainable living. The island will be developed with about 13,500 residents. There are lessons in a number of the things we have done in terms of planning. The orientation of the streets and the orientation and design of the buildings minimizes the energy used in heating and cooling and maximizes the capture of solar radiance on photovoltaic panels integrated into the buildings. The site plan and building orientations have been informed by the natural environment, and in times of maximum solar energy the development will export renewable power to the grid. This gives a 60 percent expected reduction on carbon emissions. On the transportation side, there is a ferr
