Flooding's Grey Zone in NYC: Final Thoughts

Our graphic report below details the association between the geospatial official (and unofficial) models, actual flooding, and individual perception of flood risk. From the start, we had difficulty gathering information from the public and private individuals working most closely with these flood maps, and chose to make that facet of our subject one of the core components of our narrative.

Our final project thus ended up using both existing FEMA floodplain boundaries, building data from mapPLUTO, and the extent of Sandy Inundation from the City of New York. Then we gathered our own original data by surveying individuals on the streets of Tribeca in order better understand how these maps are perceived by those they impact.

At the end of the project, we came to the conclusion that flood maps poorly convey risk, and perceptions of flood risk are inconsistent and complicated by maps that don't tell the whole story.
