Every indicator was mapped with and without the storm surge overlays. Where possible, each indicator of vulnerability was mapped on the smallest census geography that was available. In this case, absolute number of households living below the poverty level was mapped at the census tract level.
Similarly to the vulnerabilities, capacities were mapped with storm surge overlays as well. In the above left example, medical capacities are mapped. To the right is the MTA New York City subway transit system, which shows that in a category 3 or higher storm, at least 2 subway stations are located in the storm surge area.
All of the vulnerabilities and capacities were combined together and weighted according to how much of an effect they may have on the community’s overall readiness. For example, we had considered “Pre 1939 construction” to be vulnerability, but we did not consider it to be as important of a vulnerability as the number of people aged 65 and older. The numbers were totaled together, and mapped with the storm surge overlay to create a “total” vulnerability analysis.
