Gentrification is a highly contested issue in modern urban planning and development.  While gentrification does have positives influences, such cleaning up neighborhoods and attracting amenities to once under-served areas, it often results in the displacement of existing communities.  Raising property and living cost in gentrified neighborhoods often alienate the people already living there and force them to leave their homes and their communities.  

The goal of this proposal is to encourage development and economic growth of under-served census tracts without displacing current residents through property tax subsidies.  Using a combination of GIS, Grasshopper, and census data team retroactively analyzed Manhattan census tracts that were ungentrified in 2000 to evaluate how much subsidized revenue could have been generated through development.  

The outcome leads to a better understand of the amount of tax required and the number of households that could be protected from displacement through such a tax.
