Materials: Foam core and museum board base, plastic eggcrate louver, strap-ties, nuts, bolts, washers and reclaimed wires.
With a little more time, I might look into how other systems fit into the model (underground aquifers, sewage, etc.). In the meantime, check out The Welikia Project (an extension of the Mannahatta Project) and a diagram of Manhattan's changing shoreline over the course of the past 400 years.
UPDATE: this map from 1880 is quite interesting. It shows the street grid at the time with the original topography overlaid.
