20250507 09465600 1.0 TRUE SLR 1ft - Percent Land Area Percent Land Area in 1 Foot SLR Zone About the map: This depiction of sea level rise (SLR) zones across Puerto Rico utilizes outputs from a NOAA Coastal Services Center SLR viewer showing inundation above mean higher high water (MHHW) levels. 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 each seal level rise scenario (1ft., 4ft., and 10ft.) is calculated for each hexagonal grid, representing 0.5 sq. miles, and is symbolized using an equal interval classification scale.
