This map uses tile and elevation data from Mapbox, coupled with a GL shader to display potential sea level rise based on elevation. This approach does not take into account a variety of important factors such as tidal variability and hydrological connectivity. The mapping does not consider possible future changes in coastal geomorphology, and does not incorporate aspects of the built-environment such as ditches and other engineered attempts to channel water. Additionally, this mapping does not take into account the potential damages of storm surge and associated flooding. These types of analysis were beyond the scope of this project. For a resource that considers more factors, I would suggest climatecentral.com.
The interactive map should, consequently, not be used for planning, navigation, or scientific purposes.
Additionally, the population data from Climate Central is based on 2010 totals. The number of people affected, therefore, is based on 2010 data and does not take into account increases and decreases in population or potential future relocation.
In case anyone is interested in making something similar, I found the following technical resources useful:
