Percent Land Area in 100-Year Flood Zone
About this map:
This depiction of 100-year flood zones across Puerto Rico utilizes preliminary federally designated zones provided by Puerto Rico’s Planning Board. The hexagonal grids utilized in this representation of flooding provide a standardized method for overlaying multiple hazards each with different spatial representations. The total land area inside the 100-year flood zone is calculated for each hexagonal grid, representing 0.5 sq. miles, and is symbolized using an equal interval classification scale. |
