Title: Bedrock Depth and the Formation of the Manhattan Skyline, 1890-1915 ∗
Abstract: Skyscrapers in Manhattan need to be anchored to bedrock to prevent (possibly uneven) settling. This can potentially increase construction costs if the bedrock lies deep below the surface. The conventional wisdom holds that Manhattan developed two business centers--downtown and midtown--because the depth to the bedrock is close to the surface in these locations, with a bedrock valley in between. We measure the effects of building costs associated with bedrock depths, relative to other important economic variables in the location of early Manhattan skyscrapers (1890-1915). We find that bedrock depths had very little influence on the skyline; rather its polycentric development was due to residential and manufacturing patterns, and public transportation hubs.
