In conclusion, Hope Properties are a peculiar case compared to the percentage of flooded buildings in East and Central Harlem under current and future floodplain. Future research could: 1) Compare H&A properties to all vulnerable affordable housing in Coney Island, the Rockaways and the Lower East Side; 2) Repeat this analysis using the 500 Year Floodplain (0.2% annual chance storm) data; 3) Calculate social vulnerability (potential loss) of H&A properties and people at current and future projections; 4) Analyze the effect of inland flooding due to rainfall or blue-sky flooding that causes basement flooding.
