Water levels are relative to local Mean Higher High Water Datum. Click on icons in the map to view sea level rise simulations at specific locations. Use the vertical slider to simulate water level rise, the resulting inundation footprint, and relative depth. Oregon and Texas – Marsh tab updated with 2010 Coastal Change Analysis Program (C-CAP) land cover data Tillamook Bay, OR – Added elevation data and remapped to fill data gap Palm City, FL – Fixed elevation model and remappedĬharles and Mystic Rivers near Boston, MA – Fixed elevation model and remapped to fix dam protected area North Carolina/South Carolina border – Remapped to fix edge matching issue Maryland/Delaware border – Remapped to fix edge matching issue. Texas City, TX – Remapped to fix leveed area Port Arthur, TX – Remapped to fix leveed areaįreeport, TX – Remapped to fix leveed area Virgin Islands – Remapped with new elevation data based on 2013 lidar from NOAA San Francisco Bay, CA – Remapped to fix leveed areas. Northern South Carolina, North Carolina, Virginia, Maryland, Delaware, New Jersey, and New York – Remapped with new elevation data based on Post-Sandy lidar from USGS and NOAA National Geodetic Survey. The VDatum team is currently looking at resolving these uncertainties. These issues most likely can be attributed to subsidence, newly established datums, and changes to the understanding of NAVD88 based on new versions of the GEOID. Important – Transformation uncertainties in the "Louisiana/Mississippi–Eastern Louisiana to Mississippi Sound" regional model have been found to range from 20 to 50 centimeters in particular locations from the Mississippi River Delta north to Lake Pontchartrain.
