Left-click a point in the SLR data to show depth at that point in the bottom right corner of the map window.
The map illustrates the scale of potential flooding, not the exact location, and does not account for erosion,
subsidence, or future construction. Water levels are shown as they would appear during an average high tide.
Rising sea levels will cause daily high tides to reach farther inland.
Users should be cautious when obtaining the depths at point of interest. For some areas the shown depth is
less than the actual depth because the lidar-based DEM elevation is above the actual bare earth. Places where
the DEM elevation can be above the actual bare-earth elevation are where the DEM elevation is up in the
vegetation canopy and where it actually represents a water surface in a stream channel or bay
area and does not account for any depth below.
