Methods & Analysis
In order to understand the vulnerability to coastal and stormwater flooding in Hope and Ascendant properties I illustrate two major relations to understand properties' exposure to floods and one correlation to understand properties vulnerability. The first relation is between the number of properties located in the current and future NYC floodplains, the second relation is between properties' exposure to current and future coastal flooding and the influence of topographic elevation of Central and East Harlem. Finally I will correlate the number of 311 service calls relating to flooding (filtered by ...) with 
I used the BBL instead of the building footprint because the Bf doesn't contain basements, there are too many assumptions to be made in relationship to future floodplain and I want to use the precautionary principle b
The first map displays the number of Hope and Ascendant properties mapped at the Bor that are in the current (2015) FEMA defined floodplain and the future floodplain as projected by the New York Panel on Climate Change (NYPCC, 2014) flood maps (20, 50, 80, 100 year floodplain).
